It is a place on the base that can be passed over 6 or more places that are not in A "relative part" is a part that is located in a component part connected to the reference point location part, and is a part that indicates the position of the reference part that has been positioned. The positioning work (in this specification, "reference part positioning work" refers to work other than placement work, which refers to the location where the positional relationship of the reference point position part to the normal position of the abnormal reference point is detected.) In order to accurately position the reference part at the required position relative to the vehicle body, move the base or vehicle body or the base and vehicle body back and forth,
Refers to work that involves moving left and right, up and down, or a combination of these directions. Furthermore, "placement work" refers to the work of arranging and arranging each component part of the vehicle body measuring machine in the required state in the vehicle body measuring machine, and the work of placing the component parts that support the weight of the base on the body measuring machine. The base is placed in a state in which the weight of the base is supported by six or more points other than the vehicle body measurement device that are not in a straight line, and the weight of the base is supported by six or more points that are not in a straight line. This refers to the work of installing a normal reference point part and a reference point position part on the car body as needed.

In this specification, "one reference point" refers to a reference point described in a commercially available vehicle body dimension diagram and a location that can serve as a reference for dimensions when measuring a vehicle body. Therefore, the edges of the frame, step sills, etc. that can serve as reference points for measurements also serve as reference points. Note that among these reference points, those located at normal positions are called normal reference points, and those that are deviated from the normal position due to an accident or the like are called abnormal reference points. ) is generally rotated in the three-dimensional space in a three-dimensional space by measuring with a body measuring device and returning the body to its original normal position, which is commonly done in the automobile body maintenance industry. ing.

In addition, there are base legs that are configured to be expandable and retractable by air pressure using cylinders (this base leg has the disadvantage of requiring an expensive compressor in addition to the vehicle body measurement device). ), those with casters etc. on the underside of the base legs, those placed on the car body modification machine, and the ones that insert supports etc. under the car body measuring machine to adjust the vertical angle etc. of the car body measuring machine. Some are configured to be adjusted, while others move the vehicle body to match the position and angle of the vehicle body to the vehicle body measurement device. 2. Example of usage Perform placement work. Select two sets (i.e., four locations) of normal reference points (lO) and one abnormal reference point (lυ) located symmetrically on the vehicle body, and select the normal reference points described in the plan view of the vehicle body dimension drawing. Corresponding to the arrangement of (10), select appropriate scales on the vertical bar (1d) and set two corresponding parts (25&), and select appropriate scales on each horizontal bar (1b). Set the corresponding part (25b") of each rod-shaped body (+5) corresponding to the height from the car body reference line written on the side view of the car body dimension drawing to each normal reference point (lO). Select an appropriate scale and display it on the display (26C)

), align the display parts (26a), (26b), and (26c) with each other, and match the display parts (26a), (26b), and (26c) with each other.
), (5C) and each relative part (6a), (6b), (6C)
By aligning and matching the four normal reference points (10) and one abnormal reference point (same as the normal arrangement of lυ, the four normal reference points (16) and one reference point) Place the point position part (7) at the car body measurement m.The car body measurement device in this state is placed on the ground below the car body via the base foot 0→.The placement work is completed here. .

Next, positioning work for each of the reference parts (5a), (5b), and (5c) is performed. Hold the vehicle body measurement device in your hand and move it back and forth and left and right to position the four normal reference point portions 06) approximately directly below the normal reference point α0). And said 4
The position of the normal reference point (10) at each location ζ The four normal reference point parts (16) are each accurately located (in order to accurately locate these, depending on the shape of the normal reference point on the vehicle body, etc.) , with the normal reference point part in contact with the normal reference point, and in other cases without contacting it.) With the goal of
→ gradually extend and lift the base (1), and once each normal reference point section 06) has been lifted to the height immediately in front of each normal reference point (10), stop the lifting operation once, and The position of the normal reference point part (16) of the part is
While carefully checking the positions of the four normal reference points θ0) and the four normal reference points 06), move the vehicle body gauge II (1) by hand so that they are located directly below the normal reference point (10). Hold it and move it forward and backward and left and right to align it, then gradually extend the four base legs (+4), lift the vehicle body measurement device, and place each normal reference point section (00) at each of the four normal reference points (00). 16) Position it accurately. At this point, each of the reference parts (5a), (5b), and (5C) is located at the required position H, and the positioning work of the reference parts (5a), (5b), and (5C) is completed. Then, the reference point position part (7) is the abnormal reference point (11
) is accurately located at the normal position N (Shizu), and the position of the abnormal reference point (11) is accurately located in the three-dimensional space due to the deviation of the position of the abnormal reference point (Jun) with respect to the reference point position part (7). Shows whether it is running or not.

After that, perform the car body repair work until the abnormal reference point (11) is accurately located at the first position of the reference point position part (7), and visually check that it is accurately located. It is possible to instantly measure that the position of ) has returned to the normal position (]2).

6. The work of positioning the defect reference part is quite difficult as described above, and it is not the case that the work can be done exactly once as described above. In other words, the reference point is often located deep inside the frame on the back side of the car body, and it is not possible to see all four normal reference points at once, so the work of positioning the reference part is done for each normal reference point. However, if you try to accurately position one normal reference point at one normal reference point by moving the vehicle body measurement device back and forth or from side to side, or by extending the base foot with the handle, , other normal reference point parts that were previously accurately positioned at the positions of other normal reference points may also move and shift their positions, or the rod-shaped body may bend. Therefore, it is necessary to redo the work to accurately position the normal reference point portion. Therefore, the work is not finished just by locating the four normal reference points in order and going around once, but by repeating this several times, the four points will gradually become more accurate. is actually true. Moreover, even though the vehicle body measurement device has a size close to the vehicle body, the work of positioning the reference part is done in such a way that the position of the base and the position of the base must be adjusted so that the reference part is accurately positioned at the required position with an accuracy of mm. The angle has to be adjusted. This is because positioning the reference part is troublesome, but if you do it carelessly, for example, if you take measurements with the reference part positioned 6 degrees off from its normal position, the repaired car body will be damaged. That part will be finished with a 3 mm deviation and will move, so for safe driving of the car, to ensure that the openings and glue of each part are properly engaged, and for the accurate installation of other parts, This is because it becomes useless as a vehicle body measuring device for vehicle body repair work that requires precision. Therefore, the work of positioning the reference part is very difficult, takes a long time, and is troublesome.

[2] Laser beams are emitted from an L-shaped base with six retractable base legs that are in contact with the ground and installed slightly to the left and forward of the vehicle body, and the laser beams are transmitted to four normal reference points. This is a vehicle body measuring machine that positions the reference part by moving the base to a position and angle that accurately penetrates the ticket hanging from the vehicle.
A detailed explanation of this vehicle body measuring device will be omitted since it is considerably inferior to the vehicle body measuring device [1] in terms of difficulty in positioning the reference portion and other performance.

[6] 1 Configuration example A short center point display needle is set up in the center of a telescoping horizontal gauge to display a point on the center line of the vehicle body, and at both ends of the horizontal gauge are located symmetrically. A latching tool that can be latched to a reference point is provided in an upwardly extending state. The horizontal gauge of this configuration is 4 to 8 gauges, making it 1 set. Note that this measuring device is generally called a centering gauge.

2 Example of Usage Based on the body dimension drawing of the vehicle whose body center line has been bent or twisted due to an accident, etc., select appropriate reference points 4 to 81 (i) that should be in symmetrical positions, and Set the length of each horizontal gauge and hook according to the position of the reference point of each set, and hang 4 to 8 horizontal gauges by hooking them to the reference point of each set. If you look at the force directly in front of the vehicle, the center point display ◇1 of these scattered horizontal gauges will shift or tilt vertically and horizontally, so you can judge whether the center line of the vehicle is bent or twisted. . Car body repair work is carried out until these center point display needles appear lined up on a straight line.

6. Disadvantages The vehicle body measuring machines described in [1] and [2] above are based on the principle of measuring the distance between arbitrary reference points in the three-dimensional direction G, so there is no need to print the center line of the vehicle body. Therefore, there is no center point indicator needle that indicates a single point on the center line of the vehicle body, as is the case with centering gauges. On the other hand, the centering gauge is based on the principle of measuring the bending and torsion of one core wire of the car body.Therefore, it is completely useless as a J1 measuring instrument for car body repair. It is not used at all.

Let me explain the reason. Accident cars that require open sides often have their bodies shortened considerably in length and width. In many cases, the distance 11 between the respective reference points shrinks considerably and becomes shorter in the composite direction below -. Even if such a car body is measured using a centering gauge, there is no reference part, relative part, or other structure to measure the shortening of the distance between the respective reference points, so it is difficult to measure the shortening of the distance between the respective reference points. This is because it is impossible to measure at all, so it is completely impossible to judge how much the length and width of the car body has shrunk.

The conventional car body measuring machine J1 shown in [1] and [2] above is excellent in its measurement principle and is said to be the most advanced and easy-to-use car body measuring machine.

However, as mentioned above, in these vehicle body measuring machines,
Although the placement work and measurement work are easy and can be done in a short time, the positioning work of the reference part is extremely difficult, takes a long time, and is troublesome.

Therefore, in the automobile body maintenance industry, there is a need for a body measuring machine that can more easily and quickly perform the work of positioning the reference part, which is the cause of the long time it takes to complete a measurement. ing. In order to meet this demand, the automotive tool and measuring instrument manufacturing industry has made efforts for many years to develop such a vehicle body measuring instrument, but has not been able to do so.

SUMMARY OF THE INVENTION An object of the present invention is to provide the above-mentioned vehicle body measuring instrument, which has been the target of development efforts in the above-mentioned industries.

An embodiment of the present invention will be described with reference to FIGS. 2 and 6. In addition, Figure 2 shows the stand for car body repair work (2→
FIG. 3 is a side view showing a state in which the vehicle body (9) is fixed to the ground (13) via the vehicle body (9). FIG. 6 is a perspective view of the same, in which only the reference points of the vehicle body are shown by dotted lines, and other parts are omitted.

Configure. On the top surface of the base (1), there is a scale (not shown) consisting of a large number of vertical and horizontal lines representing positions in the front-rear and left-right directions.Select an appropriate scale from among these and paste dots of adhesive tape on it. A corresponding part) and a reference part (5) are respectively provided, and the corresponding part) and reference part (5) are attached to the corresponding part at least through the base (1), the hanging body (4) and the base foot (14). It is constructed so as to be supported at six appropriately placed locations on the vehicle body (9) and the ground (13) that are not in a straight line. A normal reference point part (]6) of a single-shaped metal fitting that can be latched to a reference point and a display part (c) made up of the lower end of a conical weight are connected by a stretchable string-like body (32), A reference point position part (7) of a T-shaped metal fitting that is configured to be suspended from the vehicle body (9) and can similarly be locked to a reference point, and a relative part (6) that is composed of the lower end of a conical weight. are connected by an extensible string-like body (8) and suspended from the vehicle body (9).Next, the usage and effect of this method will be explained.

The arrangement work is completed by locking the metal fittings (2), the normal reference point portion (16), and the reference point position portion (7) in 4) at predetermined reference points.

Next, the positioning work of the reference part (5) is performed. Hold the base (1) in your hand and move it back and forth and left and right, and adjust the length of the base legs (14) so that the corresponding part (to the corresponding part) accurately and lightly contacts the display part (to the display part). At this point, the reference part (5) is accurately located at the required position, and the positioning work of the reference part (5) is completed. And a relative part (6) to the reference part (5)
It is displayed how far the position of the abnormal reference point (11) has shifted in the three-dimensional space in the direction of , depending on the positional shift of .

All that is left to do is to repair the car body until the relative part (6) lightly contacts the reference part (5), and visually check that the contact has been made so that the abnormal reference point (11) is in its normal position (I
2) can be measured in an instant (this state is shown by a dotted line).

Note that, instead of the reference part (5) made of dotted adhesive tape shown in the embodiment of the present invention, as shown in FIG.
A long vertical rail (19) is provided on the right end of the base (1) from front to back, and a laser oscillator ψυ that emits a laser beam (c) to the left parallel to the top surface of the base (1) is attached to one side of the base (1). The base (1) is movable along the vertical rail 09).
A long horizontal rail (goods) is provided on the front end of the base (1) to emit a laser beam backward parallel to the top surface of the base (1). The front and rear reference parts (5a) and the vertical reference parts (5C) are installed movably along the
) degree, and by forming the horizontal reference part (5b) and the vertical reference part (5c) with the laser beam Q9), the reference parts (5a), (5b), and (5c) are placed on the base (
1) may be provided. In this case, the relative part (6) is easily visible by forming dotted marks on a transparent plate (b).

In addition, the normal reference point portion (16
), on the display part) and the string-like body (62) may be replaced by the following embodiment. That is, as shown in FIG.
A cylindrical indicator (1e) is provided as a part of the base (1), and a horizontal display part (26b) is located at the center of the rear end of the magnet (17) of the indicator (1e). Similarly, there is a display section (26a) in the front and back direction at the center of the right end, and a needle-shaped normal reference point section at the upper end that fits concentrically with the indicator (1e) and can slide up and down. A rod-shaped body α5) having a diameter of 06) is provided, and a scale (not shown) indicating the position in the vertical direction is provided on the side surface of the rod-shaped body α5).

), and select an appropriate scale from among them to set the vertical display section (26c). An appropriate scale on the base (1) is selected to set a corresponding portion in the front-rear direction (25a) and a corresponding portion in the left-right direction (25b).

In this specification, "six appropriately spaced locations that are not on a straight line" are located at a distance from each other that is sufficient to support the base stably to the extent that measurements can be made in the plan view. A point that includes six points that are not on a straight line. Therefore, for example, as shown in FIG.
Insert a bolt (not shown) into the body and tighten it with a nut (not shown) to close the gap (not shown) on the car body. At the left end of the base (1), install a hanging body (4) that is clamped over an appropriate length with 18), and
Those with a base foot (14) on the right end are also available with a base foot (14).
4) It is one of the bases (1) that are supported at 6 or more locations.

Furthermore, as shown in Fig. 6, the hanging body (4) may be shaped like a plate or a rod, or the hanging body (4) may be configured to maintain perpendicularity to the base (1), or the hanging body (4) may be configured to maintain perpendicularity to the base (1). ) may be composed of a vertical bar (1d) and horizontal bars (1a) and (1b).

In the present invention, it is sufficient to construct a base that can support more weight than a space on the ground and the vehicle body in a straight line at an appropriate distance by passing a bridge between the base foot and the hanging body. Therefore, two or more base legs may be provided to reduce the number of hanging bodies to one, or more hanging bodies may be provided than in the embodiments of the present invention. Further, other configurations in the embodiments of the present invention may be added as necessary.

Since the vehicle body measurement device of the present invention may be used on a vehicle body modification machine, the term "ground" in this specification includes a vehicle body modification machine and the like. In addition, in this specification, "1 base foot"
refers to a component that supports the weight of the base in contact with the ground, so for example, when a suspension body is provided at one end of the base and the other end is in contact with and supported on a car body modification machine, etc. teeth,
The contact point at the other end of the base becomes the base foot.

In the embodiment of the present invention, one of the configurations consisting of the normal reference point section, the rod-shaped body, the display section, the corresponding section, and the indicator stand, and the configuration consisting of the reference point position section, the string-shaped body, the relative section, and the reference section are different from the other. It may also be used for the other, or one may be constructed in the form of the other.

In the prior art example and the embodiment of the present invention, in order to simplify the explanation, the case where one abnormal reference point is opened is explained, but in actual vehicle body measurement work, four or more abnormal reference points are opened. It is often necessary to measure

In that case, the configurations of the reference part, relative part, reference point position part, etc. may be increased as necessary.

Depending on the placement of the hanging body and the position of the center of gravity of the base, the base may become unbalanced, so in such cases, you may place a weight at an appropriate position on the base to stabilize the base. .

The base may have any shape, structure, or combination as long as it can connect the required hanging body, base foot, corresponding part, and reference part.

Some auto body repair shops only handle specific car models, and in that case, the car body measurement equipment must be configured in advance to a certain positional relationship, length, etc. according to the car model, and then used as is. Sometimes it's okay. Therefore, the positional relationship, length, etc. of each component in the vehicle body measuring device may be configured to be unadjustable. In addition, in other cases, examples of configurations that allow adjustment of the distance between the reference point position part and the relative part, the length of the hanging body, etc., include winding up a string-like body and adjustment with screws. There are methods that change the connection position of the object or the base to the hanging body, but there is too much to list, so the others will be omitted.

The normal reference point section, the display section, the corresponding section, the reference point position section, the reference section, or the relative section may have an arrowhead shape, needle shape, cone shape, pyramid shape, hole shape, or dot shape. In addition, by marking appropriate positions on the base or other components with a writing instrument such as chalk, magnets, adhesive tape, screws, bottles, etc., or by memorizing the scale of the position, it is possible to mark the display section, corresponding section, reference section, etc. Alternatively, a configuration may be provided in which a relative portion is provided.

The structure that connects the normal reference point part and the display part, the structure that connects the reference point position part and the relative part, or the suspended body, which may include a stay extending in the horizontal direction, etc. as a reference point. In addition to the above examples, the locking structure may be hook-shaped, ring-shaped, hole-shaped, mushroom-shaped, etc., adhesive tape, screws, clamps, etc.
Any structure may be used as long as it can be locked to a reference point, such as a structure made of bolts, holes, holes, etc.

In this specification, "locking to a reference point" includes locking to a vehicle body using the reference point as a reference. for example,
As shown in Figs. 5a and 5b, the hanging body (4) is composed of a magnet 00 whose upper part is branched and has a vertically long needle (31) in its center. The magnet 0@ may be attracted and locked to the vehicle body so that the needle (61) points to the reference point. In this case, the distance between the tip of the branch-like magnet l30) and the tip of the needle (filter 1) may be quite long.

The display part, the corresponding part, the reference part, or the relative part need not be configured to be directly visible. For example, the base portion and the relative portion may be constructed so as not to be visible, and the positional relationship between them may be displayed using a digital display mechanism or the like connected to them.

Although the normal reference point section and the display section, or the reference point position section and the relative section are configured to be connected, they may be configured to be able to be separated and combined. Similarly, a hanging body may be constructed in which the part that is attached to the reference point and the other parts can be separated and connected.

The car body autopsy instrument of the present invention may be provided with scales in the front and rear, left and right, and downward directions, or may be used without providing scales and using a commercially available tape measure or the like each time. Alternatively, the measurement may be performed by using reference points located at symmetrical positions on the vehicle body, without using the vehicle body dimension drawing. Alternatively, the vehicle body may be opened while remaining on the ground.

In the embodiment of the present invention, the structure that connects the normal reference point section and the display section, the structure that connects the reference point position section and the relative section, and the hanging body have appropriate lengths in the vertical direction, and the base has vertical and horizontal directions. Although it has an appropriate length, the length may be extremely shorter or longer than the exemplified length, as long as the intended purpose can be achieved. For example, a part of the base may have an appropriate vertical length, and the hanging body connected thereto may have an extremely short Q1 configuration with only a magnet latched to a reference point.

The base is composed of two or more stages and may be a part of the base.O JL' The base may be made of aluminum, plastic, resin, etc. to make it lightweight. In this case, the base and the hanging body can be connected by using adhesive tape on the bottom of the hanging body, or by drilling a number of screw holes on the base and fixing the bottom of the hanging body with screws. Alternatively, the hanging body may be connected by providing a base having a plurality of hanging parts and hooking the hanging part at the lower end of the hanging body onto a suitable hanging part. Alternatively, the hanging body and the base may be connected together by fitting them into the base.
This may be formed.

As is clear from the above explanation, in the conventional technology, positioning the C reference part was very difficult, took a long time, and was troublesome.However, in the present invention, the work of positioning the C reference part is very difficult and takes a long time. Since the base is constructed by providing a corresponding part and a reference part on a base that supports the weight at six or more locations that are not in a straight line and are appropriately spaced from the ground and the vehicle body, the work of positioning the reference part is easy. can be carried out easily and in an extremely short time, and has the outstanding effect of being able to complete accurate J1 measurements simply and clearly in an extremely short time compared to conventional vehicle body measuring machines.

We ourselves were skeptical that the simple positioning process of the reference part as described above would accurately position the reference part at the required position, but our experiments using various car bodies showed that I would like to add that the results confirmed that there were no errors.
