Description
Technical Field
The invention relates to the technical field of shaft coupling disassembly and assembly, in particular to a disassembling device of a linear transmission cap.
Background
The coupler is a mechanical part used for coupling a driving shaft and a driven shaft in different mechanisms to enable the driving shaft and the driven shaft to rotate together to transmit torque, and couplers with different structures can be adopted in different use environments and requirements. In order to ensure sufficient transmission torque, a linear drive cap is often provided in the coupling. The linear drive cap is provided at one end thereof with a coupling groove extending in a linear direction and having a small width so that the groove shape is substantially in a linear shape, and thus the coupling groove is also referred to as a linear groove and the name of the linear drive cap is derived therefrom.
The diesel engine pump set is equipment which takes a diesel engine as power and drives pump equipment to convey a liquid medium. The diesel engine water pump takes the diesel engine as power, and the pump set is connected with the diesel engine through the elastic coupling, so that the diesel engine water pump has the advantages of advanced and reasonable structure, high efficiency, small vibration, low noise, stable and reliable operation, convenience in assembly and disassembly and the like.
The connection between the pump shaft and the coupling of the belt water pump of the diesel engine is usually realized by connecting one end of a linear transmission cap, which is back to a linear groove, with the pump shaft through threads. In order to prevent the linear drive cap and the pump shaft from loosening, when the linear drive cap and the pump shaft are connected through screw threads, a screw thread locking glue is usually coated at the joint of the linear drive cap and the pump shaft. After the pump group runs for a long time, the threads of the linear driving cap and the threads of the pump shaft are tightly meshed and difficult to disassemble.
When the linear transmission cap is disassembled in a traditional mode, the pump shaft needs to be fixed, and then the linear transmission cap is rotated to realize the disassembly of the linear transmission cap. When the pump shaft is positioned, the pump shaft is usually clamped by the aid of the cloth tape clamp to prevent the pump shaft from rotating and moving, and the pump shaft is clamped by the cloth tape clamp, so that the pump shaft is easy to slip and damage. When the inline drive cap is rotated, since the width of the inline groove is narrow, it is common to adapt to the shape of the inline groove by inserting a sheet-shaped tool having a thin thickness into the inline groove and then rotate the inline drive cap by rotating the sheet-shaped tool, and since the sheet-shaped tool is thin, operability is poor when the inline drive cap is rotated by the sheet-shaped tool.
In summary, the conventional way of disassembling the linear driving cap has difficulty in the process of disassembling the linear driving cap.

The embodiment of the application provides a dismounting device of a line transmission cap. The dismounting device of the linear transmission cap is used for dismounting the linear transmission cap from the pump shaft. One end of the linear transmission cap, which is back to the linear groove, is in threaded connection with the pump shaft. The outer peripheral surface of the pump shaft is provided with a plurality of teeth along the circumferential direction, and tooth sockets are formed between adjacent teeth.
Referring to fig. 1 and 2, the dismounting device for the in-line driving cap includes a positioning assembly 100 and a rotating assembly 200. In the process of removing the inline drive cap from the pump shaft, the positioning assembly 100 is used to position the pump shaft and the rotating assembly 200 is used to assist in rotating the inline drive cap.
As shown in fig. 1, the positioning assembly 100 includes: a first positioning arm 110 and a second positioning arm 120. The second positioning arm 120 is disposed opposite to the first positioning arm 110, so that an accommodating space 103 is formed between the first positioning arm 110 and the second positioning arm 120. A side surface of the first positioning arm 110 facing the second positioning arm 120 has at least one first protrusion 111, and a side surface of the second positioning arm 120 facing the first positioning arm 110 has at least one second protrusion 121.
When the pump shaft is positioned, the first positioning arm 110 and the second positioning arm 120 are disposed on different sides in the radial direction of the pump shaft, so that the pump shaft can be confined in the accommodation space 103. The first protruding part 111 of the first positioning arm 110 is matched with a tooth groove on one side of the pump shaft, the second protruding part 121 of the second positioning arm 120 is matched with a tooth groove on the other side of the pump shaft, and the position of the first positioning arm 110 and the position of the second positioning arm 120 are kept fixed, so that the fixed position of the pump shaft can be limited, and the pump shaft can be prevented from rotating along the circumferential direction of the pump shaft through the matching of the first protruding part 111 and the second protruding part 121 with the tooth groove of the pump shaft respectively. Therefore, when the linear transmission cap is disassembled, the pump shaft is prevented from rotating around the axis of the pump shaft by the fact that the first protruding parts 111 and the second protruding parts 121 are respectively matched with tooth grooves of the pump shaft, and therefore the defect that the traditional cotton tape clamp is easy to slip is overcome.
As shown in fig. 2, the rotating assembly 200 includes: plug-in components 210 and supplementary rotating part 220, plug-in components 210 one end be used for cooperating with a word groove of a word transmission cap, and the other end is connected with supplementary rotating part 220 to, the rotatory supplementary rotating part 220 of accessible drives plug-in components 210 rotation, and then can drive a word transmission cap rotation, in order to dismantle a word transmission cap.
With the direction in which the insertion part 210 is inserted into the linear groove as the first direction yy', the ratio of the dimension of the auxiliary rotating part 220 in the second direction to the dimension thereof in the third direction is greater than or equal to 1/2 and less than or equal to 2, wherein the second direction and the third direction are any two different directions perpendicular to the first direction. It is to be understood that, taking the first direction yy 'as a longitudinal direction, any direction along the cross section of the auxiliary rotating portion 220 is perpendicular to the first direction yy', that is, the second direction and the third direction are respectively any two different directions along the cross section of the auxiliary rotating portion 220. In the embodiment of the present application, since the ratio of the size of the auxiliary rotating portion 220 in the second direction to the size thereof in the third direction is greater than or equal to 1/2 and less than or equal to 2, the size of the auxiliary rotating portion 220 in any two different directions in cross section is more balanced (not too thin compared to a sheet-shaped tool), thereby facilitating the operation when the auxiliary rotating portion 220 is rotated manually or by means of a tool.
When the dismounting device of the linear transmission cap is used for dismounting the linear transmission cap and positioning the pump shaft by adopting the positioning assembly 100, the defect that the traditional cloth tape clamp is easy to slip is overcome because the pump shaft is prevented from rotating around the axis of the pump shaft by respectively matching the first protrusion part 111 and the second protrusion part 121 with the tooth grooves of the pump shaft. When the inline rotatable cap is rotated by means of the rotating assembly 200, since the ratio of the size of the auxiliary rotating portion 220 in the second direction to the size thereof in the third direction is greater than or equal to 1/2 and less than or equal to 2, the size of the auxiliary rotating portion 220 in any two different directions in cross section is more balanced (not too thin compared to a sheet-shaped tool), thereby being easy to operate when the auxiliary rotating portion 220 is rotated manually or by means of a tool. Therefore, the linear driving cap is easy to disassemble through the disassembling device of the linear driving cap.
In an embodiment, a side surface of the first positioning arm 110 facing the second positioning arm 120 has a plurality of first protrusions 111 arranged at intervals, and a first groove 101 is formed between adjacent first protrusions 111. A side surface of the second positioning arm 120 facing the first positioning arm 110 has a plurality of second protrusions 121 disposed at intervals, and a second groove 102 is formed between adjacent second protrusions 121.
Specifically, as shown in fig. 1, since the first protruding portions 111 are disposed at intervals, a first groove 101 is formed between adjacent first protruding portions 111, when the pump shaft is positioned, the first protruding portions 111 are engaged with the tooth spaces on one side of the pump shaft, and then the first groove 101 can be engaged with the tooth spaces on one side of the pump shaft, and similarly, when the pump shaft is positioned, and the second protruding portions 121 are engaged with the tooth spaces on the other side of the pump shaft, then the second groove 102 can be engaged with the tooth spaces on the other side of the pump shaft, so that the pump shaft can be more effectively and reliably prevented from rotating along the circumferential direction.
As shown in fig. 1, in the present embodiment, the number of the first protrusion 111 and the second protrusion 121 is four. Of course, the number of the first protrusions 111 may also be two, three, five, etc. in other numbers. The number of the second protrusions 121 may also be two, three, five, etc. in other numbers.
As shown in fig. 1, in the present embodiment, the first protrusion 111 has a helical tooth shape, the first groove 101 has a helical groove shape, the second protrusion 121 has a helical tooth shape, and the second groove 102 has a helical groove shape. Because the teeth of the pump shaft are oblique teeth, and the tooth sockets are oblique tooth sockets, the first protruding part 111 and the second protruding part 121 can be better matched with the tooth sockets of the corresponding pump shaft, and the first groove 101 and the second groove 102 can be better matched with the tooth sockets of the corresponding pump shaft.
Referring to fig. 1, in an embodiment, the positioning assembly 100 further includes a first connecting portion 130. One end of the first connecting portion 130 is rotatably connected to one end of the first positioning arm 110, the other end of the first connecting portion 130 is rotatably connected to one end of the second positioning arm 120, and the first connecting portion 130 is located at the same end of the first positioning arm 110 and the second positioning arm 120.
Specifically, in fig. 1, the first connection portion 130 is located at the upper ends of the first and second positioning arms 110 and 120. Since the first connecting portion 130 is located at the same end of the first positioning arm 110 and the second positioning arm 120, the accommodating space 103 defined by the first connecting portion 130, the first positioning arm 110 and the second positioning arm 120 is in a groove shape.
Because one end of the first connecting portion 130 is rotatably connected with one end of the first positioning arm 110, and the other end of the first connecting portion 130 is rotatably connected with one end of the second positioning arm 120, the first positioning arm 110 can rotate relative to the first connecting portion 130 and/or the second positioning arm 120 can rotate relative to the first connecting portion 130, so that the first positioning arm 110 and the second positioning arm 120 are relatively opened to enlarge the accommodating space 103, thereby facilitating the entry of the pump shaft from the opening of the accommodating space 103, and then the first positioning arm 110 and the second positioning arm 120 are relatively closed through manual operation or by means of tool operation, reducing the accommodating space 103, so that the first positioning arm 110 and the second positioning arm 120 clamp the pump shaft to position the pump shaft, and facilitating operation.
In one embodiment, the strength of the material used for the insertion part 210 is greater than that of the material used for the auxiliary rotating part 220.
Specifically, when the insertion part 210 drives the linear driving cap to rotate, the insertion part 210 receives acting forces from the auxiliary rotating part 220 and the linear driving cap, respectively. Because the insertion part 210 is used for being matched with the straight groove, the shape of the insertion part is matched with that of the straight groove, and the thickness of the insertion part is thinner, so that the stress area of the insertion part 210 is relatively smaller, and the insertion part 210 is made of a material with higher strength and is not easy to damage.
Because the auxiliary rotating portion 220 is along the comparatively balanced of arbitrary two different direction's size on the cross section to when rotating auxiliary rotating portion 220 through manual or with the help of the instrument, when the manual effort that auxiliary rotating portion 220 received or the effort of instrument, the atress area of auxiliary rotating portion 220 is great relatively, and consequently, the less material of auxiliary rotating portion 220 intensity can save cost.
Referring to fig. 2, in an embodiment, the inserting portion 210 includes: the insertion portion 211 and the second connection portion 212 fixedly connected with the insertion portion 211, the insertion portion 211 is used for being matched with the straight groove. The auxiliary rotating portion 220 is provided with a fitting groove 201, and the opening of the fitting groove 201 faces a direction (i.e., the first direction yy') in which the insertion portion 211 is inserted into the linear groove, and the second connection portion 212 is fitted with the fitting groove 201.
Specifically, since the material of the insertion part 210 is different from that of the auxiliary rotating part 220, the two parts may be separately processed and then assembled. The second connection portion 212 is engaged with the engagement recess 201, so that the insertion portion 210 is easily assembled with the auxiliary rotation portion 220.
Referring to fig. 2, in an embodiment, the second connection portion 212 is provided with a first insertion hole 202. The auxiliary rotation portion 220 is provided with a second insertion hole 203, and the second insertion hole 203 corresponds to the first insertion hole 202. The rotating assembly 200 further comprises: the third connecting part 230, the third connecting part 230 is inserted and matched with the second jack 203 and the first jack 202 respectively.
Specifically, the third connecting portion 230 is, for example, a connecting column, a connecting pin, etc. and the third connecting portion 230 is respectively inserted into and engaged with the second insertion hole 203 and the first insertion hole 202, so as to ensure that the insertion portion 210 is reliably engaged with the auxiliary rotating portion 220.
In one embodiment, the hole wall of one of the first receptacle 202 and the second receptacle 203 is tightly fitted to the third connecting portion 230, and the hole wall of the other receptacle is spaced from the third connecting portion 230.
Specifically, in the present embodiment, the hole wall of the first insertion hole 202 is tightly fitted to the third connection portion 230, and a gap is provided between the hole wall of the second insertion hole 203 and the third connection portion 230, so that the inner diameter of the second insertion hole 203 is larger than that of the first insertion hole 202, and thus, when the third connection portion 230 is respectively fitted to the first insertion hole 202 and the second insertion hole 203, even if there is a certain dimensional error and a certain positional error between the first insertion hole 202 and the second insertion hole 203, the first insertion hole 202 and the second insertion hole 203 of the third connection portion 230 can still be easily fitted to each other, thereby facilitating the third connection portion 230 to be completely fitted to the second connection portion 212 and the auxiliary rotation portion 220.
In other embodiments, the hole wall of the second socket 203 may be tightly fitted with the third connecting portion 230, and a gap is formed between the hole wall of the first socket 202 and the third connecting portion 230, so that the inner diameter of the first socket 202 is larger than that of the second socket 203, which also facilitates the third connecting portion 230 to be assembled with the second connecting portion 212 and the auxiliary rotating portion 220.
In one embodiment, the device for detaching the in-line drive cap further comprises: a rotary output assembly (not shown). The rotary output assembly includes: sleeve and driving medium. The transmission part is used for driving the sleeve to rotate. The sleeve is sleeved on the auxiliary rotating portion 220 and is adapted to the auxiliary rotating portion 220. The auxiliary rotating portion 220 has a polygonal cross-section with the first direction as a longitudinal direction.
Specifically, since the auxiliary rotary part 220 has a polygonal cross-section, the sleeve and the auxiliary rotary part 220 can coaxially rotate when the sleeve and the auxiliary rotary part 220 are fitted. At this time, the sleeve can be driven by the driving member, so as to indirectly drive the auxiliary rotating portion 220 to rotate, thereby facilitating the operation.
As shown in fig. 2, in the present embodiment, the cross section of the auxiliary rotating portion 220 is a regular hexagon, but it is understood that the cross section of the auxiliary rotating portion 220 may be a triangle, a quadrangle, a pentagon, an octagon, etc., and the auxiliary rotating portion 220 may be a regular polygon or a non-regular polygon.
In other embodiments, the removal device for the inline drive cap may not include a rotary output assembly, but rather a rotary output assembly may be separately configured or otherwise procured.
In one embodiment, the direction of extension of the transmission member is arranged at an angle to the axial direction of the sleeve. For example, the transmission member may be a handle by which the sleeve is conveniently manually rotated.
In other embodiments, the transmission member may also be a transmission shaft, and the transmission shaft is coaxially connected to the sleeve, and can drive the transmission shaft to rotate by means of the motor, so as to drive the sleeve to rotate.
In one embodiment, the device for detaching the in-line drive cap further comprises an electric heating device for heating the in-line drive cap.
Specifically, the electric heating device is, for example, an electric blower.
