An existing vertical grinder is suitable for grinding a workpiece. The vertical grinder includes a base, a working plate, a tool magazine, two linear slides, a spindle device, and a grinding wheel dressing device. The base includes a worktable, two uprights arranged on the worktable at intervals along a left and right direction, and a beam spanning the uprights. The top of the worktable defines a trimming area, a working area and a tool changing area in order from left to right along the left and right direction. The working plate is rotatably arranged in the working area and used for placing the workpiece. The tool magazine is arranged in the tool change area and includes a plurality of grinding wheels. The linear slide rails are arranged on the beam. The main shaft device is reciprocally arranged on the linear slide rails along the left and right directions, and is used for clamping any selected grinding wheel and driving the grinding wheel to rotate. The grinding wheel dressing device is arranged in the dressing area. When in use, the workpiece is vertically fixed on the work plate, and the work plate drives the work to rotate. The spindle device moves to the work area by the linear slide rails so that the grinding wheel can contact the work The inner diameter, outer diameter and end face are ground. However, the grinding wheel is prone to wear problems after multiple grinding processes. At this time, the grinding wheel dressing device can be used to re-dress the grinding wheel surface to restore its grinding performance.

However, the arrangement of the existing vertical grinder makes the movement stroke of the spindle device during grinding wheel processing, dressing, and tool change almost equal to the length of the worktable in the left-right direction, and the longer movement stroke causes the beam to sag and deform. The larger the amount, the problem of structural deformation is prone to occur.

Therefore, the object of the present invention is to provide a vertical grinding machine with a grinding wheel dressing device that shortens the moving stroke of the spindle device.

Therefore, the new vertical grinder with a grinding wheel dressing device includes a base, a working plate, a tool magazine, a spindle device, a moving device, and a grinding wheel dressing device.

In this embodiment, the grinding wheel dressing device 7 uses the single-point dressing pen 75 to dress the grinding wheel 41. However, in other embodiments, a roller-type dressing spindle 76 may be installed, or the single-point dressing spindle 76 may be installed at the same time. The type dressing pen 75 and the roller type dressing spindle 76 (see FIG. 2).

A first axis L1 parallel to the Z-axis direction and passing through the rotating disk 72 is defined, and a second axis L2 perpendicular to the X-axis direction and the first axis L1 is defined.

The device body 71 has a first accommodating cavity 711 arranged around the first axis L1 and opened upward, and a second accommodating cavity 712 extending along the second axis L2 and communicating with the first accommodating cavity 711 . The rotating disk 72 has a rotating part 721 arranged around the first axis L1 and located above the first accommodating cavity 711, and a rotating part 721 deviated from the first axis L1 and arranged on the side of the rotating part 721 for the trimming seat 73 set of the bearing portion 722. The transmission unit 74 can be controlled to drive the rotating disk 72 to rotate around the first axis L1, and has a rack 741 disposed in the second accommodating cavity 712 and movable along the second axis L2, and a rack A gear 742 arranged in the first accommodating cavity 711 connected to the rotating disk 72 and meshing with the rack 741 and capable of cooperating with the rack 741 for transmission. The gear 742 can convert the linear motion of the rack 741 into rotation movement. In this embodiment, the transmission unit 74 drives the rack 741 to move by a hydraulic pump, but it is not limited to this.

1, 4, 5, 6, the rotating disk 72 can be driven by the transmission unit 74, and together with the trim seat 73 and the avoidance space 77 relative to the device body 71 in a first position (as shown in Figure 4 ), a second position (as shown in Figure 5), and a third position (as shown in Figure 6). In the first position, the dressing seat 73 is close to the working plate 3, the avoiding space 77 is close to the tool magazine 4, and in the third position, the dressing seat 73 is close to the tool magazine 4, and the avoiding space 77 is close to the tool magazine 4 When the working plate 3 is in the second position, the trimming seat 73 is far away from the beam 22 and is located between the first position and the third position, and the avoidance space 77 is close to the beam 22.

When in use, the workpiece is fixed to the working plate 3, and the spindle device 5 is moved to the working area 211, and the grinding wheel 41 can contact the workpiece and perform grinding processing on the workpiece.

1 and 4, when the selected grinding wheel 41 is to be replaced, the spindle device 5 will perform tool change between the dressing area 212 and the tool change area 213. At this time, the dressing seat 73 is moved to the first A position, and the avoidance space 77 is close to the tool magazine 4 so that the grinding wheel dressing device 7 avoids interfering with the operation of the spindle device 5 and the tool magazine 4 and other mechanisms.

1 and 6, when the inner diameter and outer diameter of the workpiece are to be grinded, the spindle device 5 will move between the dressing area 212 and the working area 211 to target the workpiece fixed to the working plate 3. The workpiece is processed. At this time, the dressing seat 73 is moved to the third position and the avoiding space 77 is brought close to the work plate 3, so that the grinding wheel dressing device 7 avoids interfering with the spindle device 5, the work plate 3 and the Operation between artifacts.

For the configuration of another spindle device 5, please refer to Figures 1, 5 and 7. When you want to grind the end face of the workpiece, you need to replace another spindle device 5 capable of end face processing (as shown in Figure 7). 5 The grinding wheel 41 can be arranged at 90 degrees so that the grinding wheel 41 itself is axially parallel to the X axis direction and the outer peripheral surface can touch the workpiece along the Z axis direction to grind the end surface of the workpiece. , Moving the dressing seat 73 to the second position can make the dressing seat 73 leave the path of the grinding wheel 41 and make the avoidance space 77 relatively close to the beam 22 to prevent the grinding wheel dressing device 7 from interfering with the spindle device 5, The operation of the grinding wheel 41 and the working plate 3.

Referring to Figures 1, 4, and 6, when the grinding wheel 41 is to be dressed, the dressing seat 73 can be moved to the first position or the third position, and the spindle device 5 can drive the grinding wheel 41 to move to the avoidance space 77 , So that the single-point dressing pen 75 contacts the outer peripheral surface of the grinding wheel 41 and dressing the grinding wheel 41.

It is worth noting that after the present invention sets the grinding wheel dressing device 7 between the tool magazine 4 and the work plate 6, even when the spindle device 5 has the longest movement stroke, that is, when the inner diameter grinding process is performed, the The spindle device 5 needs to move to the side of the working area 211 adjacent to the trimming area 212. Compared with the previous proposal, the movement stroke is almost equal to the length of the working table 21. This proposal can still effectively reduce the movement stroke and improve the beam 22 The situation of sagging deformation under force.

Based on the above description, the advantages of the foregoing embodiment can be summarized as follows: The grinding wheel dressing device 7 is arranged in the dressing area 212 and is located between the tool magazine 4 and the working plate 3, which can shorten the movement stroke required by the spindle device 5 , And can improve the structural deformation of the beam 22. The grinding wheel dressing device 7 can rotate around the first axis L1, and the position of the avoidance space 77 can be adjusted according to the use situation, and the grinding wheel dressing device 7 can be prevented from interfering with the operation of other mechanisms due to the setting in the dressing area 212.

However, the above-mentioned are only examples of the present model. When the scope of implementation of the present model cannot be limited by this, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
