Description

Technical Field

[0001] This application relates to the technical field of motor housing grinding, and specifically relates to a housing grinding device for motor production. Background Art

[0002] As an important device for converting electrical energy into mechanical energy, motors cover most industrial and civil fields. In mechanical manufacturing, such as machine tools, presses, rolling mills, etc., motors are the core components of driving equipment. In the mining industry, motors are used to drive equipment such as hoists, conveyor belts, and fans inside mines to operate.

[0003] Since the surface of the housing after casting or machining may have burrs, scratches, or unevenness, it is necessary to grind the surface of the housing to make the appearance of the housing neat. And because some housings need to be painted, anodized, etc., grinding the surface of the housing can enhance the adhesion strength of the coating and avoid the situation of peeling or unevenness caused by rough surface.

[0004] Due to the different types of motors, the shapes of motor housings are inconsistent. When grinding a circular motor housing, the motor housing can be ground by driving the motor housing to rotate. When grinding a square motor housing, the motor housing needs to be clamped, and a driving roller is used to drive the abrasive belt to grind the side wall of the square motor housing.

[0005] Referring to the Chinese patent application document with the publication number CN117300840A and the theme name of a housing grinding device for motor production, this device is provided with a grinding mechanism that can be rotationally adjusted. When the motor housing needs to be ground, the motor housing is placed on the grinding mechanism, and after one end is ground, the grinding mechanism is driven to rotate so that all parts of the motor housing can be ground.

[0006] For the above technical solution, when grinding the motor housing, abrasive blocks or abrasive belts are usually used to grind the motor housing. Using an abrasive belt can apply uniform pressure to the motor housing, making the grinding process more uniform to reduce uneven grinding on the surface of the motor housing. When grinding the side wall of a square housing, since it is necessary to grind the installation groove on the side wall of the square housing, the square housing needs to be rotated. After rotation, the position of the abrasive belt or abrasive block needs to be adjusted to move the abrasive belt or abrasive block into the installation groove to grind the installation groove of the square housing. When grinding the installation groove, the positions of the square housing and the abrasive belt or abrasive block need to be adjusted, which affects the grinding efficiency. Summary of the Invention

[0007] In view of this, the present application provides a housing grinding device for motor production, aiming at solving the problem that the grinding of the installation groove of a square motor requires shutdown adjustment.

[0009] Place the square motor housing on the clamping mechanism, and make the clamping mechanism clamp the square motor housing. By rotating the cross connecting frame, make the two end points of the cross connecting frame contact the grinding belt, and make the middle position between the two end points abut against the side wall of the square motor housing to grind the side wall of the square motor housing. After grinding the side wall of the square motor housing, drive the cross connecting frame to rotate, make one end point of the cross connecting frame contact the grinding belt, and make the clamping mechanism rotate to drive the square motor housing to rotate, so that one end point of the cross connecting frame moves to the installation groove of the square motor housing to grind the installation groove.

Detailed implementation manners

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the Figures 1 - 8 of the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present application.

[0036] As Figure 1 shown, this embodiment provides a grinding device for the housing of a motor production, including a mounting frame 1, a clamping mechanism 2, a grinding mechanism, an abutting mechanism, an adjusting mechanism, a tensioning mechanism, a moving mechanism, and a driven mechanism. The clamping mechanism 2 is arranged at the middle position of the mounting frame 1. The clamping mechanism 2 is used to abut against the inner position of the motor housing, so that the motor housing is located in the middle of the mounting frame 1. The abutting mechanism is used to abut against the side wall of the motor housing. The grinding mechanism is used to grind the motor housing. The abutting mechanism is used to make the abrasive belt 36 in the grinding mechanism close to the side wall of the motor housing. The adjusting mechanism is used to drive the abutting mechanism to make fine adjustments when grinding the mounting groove of the motor housing. The tensioning mechanism is used to control the tension degree of the abrasive belt 36. The moving mechanism is used to drive the motor housing to move in the horizontal direction. The driven mechanism is used to make the abutting mechanism rotate synchronously with the rotation direction of the motor housing when adjusting the motor housing.

[0037] As Figure 5 、 Figure 6 and Figure 7As shown, the clamping mechanism 2 includes a sliding plate 21, a clamping cylinder 22, an inclined cutting block 23, a clamping plate 24, a clamping block 241 and an abutting block 25. The sliding plate 21 is slidably connected to the mounting frame 1. The clamping cylinder 22 is rotatably connected to the sliding plate 21. The output shaft of the clamping cylinder 22 penetrates through the sliding plate 21. The inclined cutting block 23 is fixedly connected to the output shaft of the clamping cylinder 22. There are multiple inclined cutting blocks 23, and the multiple inclined cutting blocks 23 are axially arranged in an array on the output shaft of the clamping cylinder 22. The clamping plate 24 is rotatably connected to the sliding plate 21, and the clamping plate 24 is arranged in a frustum shape. The clamping block 241 is slidably connected to the clamping plate 24, and there are multiple clamping blocks 241. The number of clamping blocks 241 corresponds to the number of inclined cutting blocks 23. The clamping blocks 241 are axially arranged in an array on the clamping plate 24. There are multiple abutting blocks 25. A single abutting block 25 is fixedly connected to the clamping block 241 and is arranged toward the side close to the output shaft of the clamping cylinder 22.

[0038] When it is necessary to clamp the motor housing, place the motor housing on the side of the sliding plate 21 away from the clamping cylinder 22, and start the clamping cylinder 22 to move the output shaft of the clamping cylinder 22 toward the side close to the motor housing. When moving to a certain extent, the inclined cutting block 23 on the output shaft of the clamping cylinder 22 abuts against the abutting block 25. At this time, the inclined cutting block 23 pushes the abutting block 25 and the clamping block 241 to move toward the inner wall of the motor housing, so that the inner wall of the motor housing abuts against the clamping block 241. Due to the axial array distribution of the clamping blocks 241, when all the clamping blocks 241 abut against the inner wall of the motor housing, the centering of the motor housing is completed.

[0039] As Figure 5 and Figure 6 As shown, the moving mechanism includes a moving motor 26, a moving lead screw 27, a rotating motor 28, a rotating gear 29 and a driven gear 291. The moving motor 26 is fixedly connected to the mounting frame 1 and is arranged at the middle position of the mounting frame 1. The moving lead screw 27 is fixedly connected to the output shaft of the moving motor 26. The moving lead screw 27 and the sliding plate 21 are connected by a threaded connection. The rotating motor 28 is fixedly connected to the sliding plate 21. The rotating gear 29 is fixedly connected to the output shaft of the rotating motor 28. The driven gear 291 is fixedly connected to the clamping cylinder 22 and is fixedly connected to the clamping plate 24.

[0040] When it is necessary to drive the motor housing to move, start the moving motor 26 to make the output shaft of the moving motor 26 rotate. The rotation of the output shaft of the moving motor 26 drives the moving lead screw 27 to rotate. Due to the threaded connection between the moving lead screw 27 and the sliding plate 21, the moving lead screw 27 can drive the sliding plate 21 to move in the horizontal direction during rotation. When it is necessary to adjust the angle of the motor housing, start the rotating motor 28 to make the output shaft of the rotating motor 28 rotate. The rotation of the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate. The rotation of the rotating gear 29 drives the driven gear 291 to rotate, so that the driven gear 291 drives the clamping cylinder 22 and the clamping plate 24 to rotate, thereby realizing the adjustment of the angle of the motor housing.

[0041] As Figure 2 and Figure 3 shown, the grinding mechanism includes a connecting plate 3, a grinding belt 36, a driving roller 7 and a driving motor 71. The connecting plate 3 is fixedly connected to the mounting frame 1. The grinding belt 36 is sleeved on the connecting plate 3. The driving roller 7 is rotatably connected to the connecting plate 3. The driving motor 71 is fixedly connected to the connecting plate 3, and the output shaft of the driving motor 71 and the driving roller 7 are connected by a belt drive. When it is necessary to drive the grinding belt 36 to rotate, start the driving motor 71. The driving motor 71 drives the driving roller 7 to rotate, and the driving roller 7 drives the grinding belt 36 to rotate.

[0042] As Figure 2 shown, the abutting mechanism includes an abutting cylinder 31, an abutting plate 32, a connecting shaft 33, a cross connecting frame 34 and an abutting roller 35. The abutting cylinder 31 is fixedly connected to the connecting plate 3. The abutting plate 32 is fixedly connected to the output shaft of the abutting cylinder 31 and is arranged on the side of the output shaft of the abutting cylinder 31 away from the abutting cylinder 31. The connecting shaft 33 is rotatably connected to the abutting plate 32. The cross connecting frame 34 is rotatably connected to the connecting shaft 33. The abutting roller 35 is rotatably connected to the cross connecting frame 34 and is arranged at the end point position of the cross connecting frame 34.

[0043] When grinding the side wall of the circular motor, drive the grinding belt 36 to rotate through the driving motor 71, and start the abutting cylinder 31 to make the abutting cylinder 31 drive the cross connecting frame 34 to move toward the side close to the grinding belt 36. Rotate the cross connecting frame 34 so that two of the end points of the cross connecting frame 34 abut against the inner side wall of the grinding belt 36, and make the grinding belt 36 at the middle position between the two end points of the cross connecting frame 34 abut against the side wall of the circular motor housing, and grind the side wall of the circular motor housing driven by the driving motor 71. When grinding the side wall of the square motor, repeat the above operation.

[0044] When grinding the installation groove of the square motor, start the rotating motor 28, so that the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate. The rotation of the rotating gear 29 drives the driven gear 291 to rotate, and the rotation of the driven gear 291 drives the clamping cylinder 22 to rotate, so that the cross connecting frame 34 changes from contacting the grinding belt 36 at two endpoints to contacting the grinding belt 36 at only one endpoint. After the contact, start the transmission motor 71, so that the transmission motor 71 drives the grinding belt 36 to rotate, and grind the installation groove of the square motor through the grinding belt 36.

[0045] As Figure 4 shown, the adjustment mechanism includes a first adjustment block 4, an adjustment ring 41, a second adjustment block 42, an adjustment spring 43 and an adjustment motor 9. The first adjustment block 4 is fixedly connected to the cross connecting frame 34. The adjustment ring 41 is detachably connected to the first adjustment block 4. The second adjustment block 42 is fixedly connected to the connecting shaft 33, and the second adjustment block 42 and the adjustment ring 41 are detachably connected. The adjustment spring 43 is sleeved on the adjustment ring 41, and both ends of the adjustment spring 43 are fixedly connected to the first adjustment block 4 and the second adjustment block 42 respectively. The adjustment motor 9 is fixedly connected to the connecting plate 3, and the output shaft of the adjustment motor 9 and the connecting shaft 33 are connected by a gear transmission method.

[0046] When it is necessary to drive the cross connecting frame 34 to rotate, start the adjustment motor 9, so that the output shaft of the adjustment motor 9 rotates, and drives the connecting shaft 33 to rotate through a gear transmission method. Since the connecting shaft 33 and the cross connecting frame 34 are rotationally connected, the connecting shaft 33 cannot drive the cross connecting frame 34 to rotate at the beginning of rotation. At this time, the adjustment spring 43 at the middle position between the first adjustment block 4 and the second adjustment block 42 is in a compressed state. After rotating to a certain extent, make the cross connecting frame 34 located at the middle position of the installation groove, and turn off the adjustment motor 9, so that the two side walls of the installation groove push the cross connecting frame 34 to make the cross connecting frame 34 located at the middle position of the installation groove.

[0047] As Figure 4 shown, the tensioning mechanism includes a tensioning block 5, a tensioning rod 51, a tensioning spring 52 and a tensioning roller 53. The tensioning block 5 is fixedly connected to the connecting plate 3. The tensioning rod 51 is slidably connected to the tensioning block 5. The tensioning spring 52 is fixedly connected to the tensioning block 5, and one end of the tensioning spring 52 is fixedly connected to the tensioning block 5. The tensioning roller 53 is rotationally connected to the tensioning rod 51 and is arranged at the end of the tensioning rod 51 away from the tensioning block 5. The tensioning roller 53 abuts against the inner side wall of the grinding belt 36.

[0048] When the cross connector 34 changes from the abutting rollers 35 at both ends abutting against the side wall of the abrasive belt 36 to the abutting roller 35 at a single end abutting against the side wall of the abrasive belt 36, the abrasive belt 36 is in a slack state due to the lack of part of the support. Since the abrasive belt 36 is in a slack state, the tensioning roller 53 lacks the pulling of the abrasive belt 36, and under the push of the tensioning spring 52, the tensioning roller 53 moves towards the side close to the abrasive belt 36, so that the tensioning roller 53 pushes the abrasive belt 36 to be tightened.

[0049] As Figure 3 and Figure 8 shown, the driven mechanism includes an abutting rod 6, an abutting spring 61, a receiving plate 62, a sliding groove 8 and a sliding block 81. The abutting rod 6 is fixedly connected to the abutting plate 32, the abutting spring 61 is fixedly connected to the abutting rod 6, the receiving plate 62 is fixedly connected to the abutting cylinder 31 and is arranged on the side of the abutting cylinder 31 close to the output shaft. The abutting rod 6 and the receiving plate 62 are slidably connected, the side of the abutting spring 61 away from the abutting rod 6 is fixedly connected to the receiving plate 62, the sliding groove 8 is formed in the connecting plate 3, and the sliding block 81 is fixedly connected to the abutting plate 32 and is slidably connected in the sliding groove 8.

[0050] When the cross connector 34 changes from the abutting rollers 35 at both ends abutting against the side wall of the abrasive belt 36 to the abutting roller 35 at a single end abutting against the side wall of the abrasive belt 36, due to the limitation of the length of the cross connector 34, the abutting plate 32 moves towards the side away from the side wall of the square motor, so that the abutting rod 6 pushes the abutting spring 61 to be compressed, and the sliding block 81 located on the abutting plate 32 slides in the sliding groove 8.

[0051] When the present application is in use, the motor housing is placed on the side of the sliding plate 21 away from the clamping cylinder 22, and the clamping cylinder 22 is started, so that the output shaft of the clamping cylinder 22 moves towards the side close to the motor housing. When moving to a certain extent, the inclined cutting block 23 on the output shaft of the clamping cylinder 22 abuts against the abutting block 25, and at this time, the inclined cutting block 23 pushes the abutting block 25 and the clamping block 241 to move towards the inner side wall of the motor housing, so that the inner side wall of the motor housing abuts against the clamping block 241. Due to the axial array distribution of the clamping blocks 241, when all the clamping blocks 241 abut against the inner side wall of the motor housing, the centering of the motor housing is completed.

[0052] Start the moving motor 26 to rotate the output shaft of the moving motor 26. The rotation of the output shaft of the moving motor 26 drives the moving lead screw 27 to rotate. Due to the threaded connection between the moving lead screw 27 and the sliding plate 21, the moving lead screw 27 can drive the sliding plate 21 to move horizontally during rotation. When it is necessary to adjust the angle of the motor housing, start the rotating motor 28 to rotate the output shaft of the rotating motor 28. The rotation of the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate. The rotation of the rotating gear 29 drives the driven gear 291 to rotate, so that the driven gear 291 drives the clamping cylinder 22 and the clamping plate 24 to rotate, thereby realizing the adjustment of the angle of the motor housing.

[0053] When grinding the side wall of the circular motor, drive the abrasive belt 36 to rotate through the drive motor 71, and start the abutting cylinder 31 to drive the cross connecting frame 34 to move toward the side close to the abrasive belt 36. Rotate the cross connecting frame 34 so that two of the endpoints of the cross connecting frame 34 abut against the inner side wall of the abrasive belt 36, and make the abrasive belt 36 at the middle position between the two endpoints of the cross connecting frame 34 abut against the side wall of the circular motor housing, and grind the side wall of the circular motor housing driven by the drive motor 71. When grinding the side wall of the square motor, repeat the above operation.

[0054] When grinding the installation groove of the square motor, start the rotating motor 28 to drive the rotating gear 29 to rotate through the output shaft of the rotating motor 28. The rotation of the rotating gear 29 drives the driven gear 291 to rotate. The rotation of the driven gear 291 drives the clamping cylinder 22 to rotate, so that the cross connecting frame 34 changes from abutting against the abrasive belt 36 at both endpoints to contacting the abrasive belt 36 at a single endpoint. After contact, start the drive motor 71 to drive the abrasive belt 36 to rotate, and grind the installation groove of the square motor through the abrasive belt 36.

[0055] When it is necessary to drive the cross connecting frame 34 to rotate, start the adjustment motor 9 to rotate the output shaft of the adjustment motor 9, and drive the connecting shaft 33 to rotate through a gear transmission method. Since the connecting shaft 33 and the cross connecting frame 34 are rotationally connected, the connecting shaft 33 fails to drive the cross connecting frame 34 to rotate at the beginning of rotation. At this time, the adjustment spring 43 at the middle position between the first adjustment block 4 and the second adjustment block 42 is in a compressed state. After rotating to a certain extent, make the cross connecting frame 34 located at the middle position of the installation groove, and turn off the adjustment motor 9 to make the two side walls of the installation groove push the cross connecting frame 34 so that the cross connecting frame 34 is located at the middle position of the installation groove.

[0056] When the cross connecting frame 34 changes from the abutting rollers 35 at both ends abutting against the side wall of the abrasive belt 36 to the abutting roller 35 at a single end abutting against the side wall of the abrasive belt 36, due to the limitation of the length of the cross connecting frame 34, the abutting plate 32 moves towards the side away from the side wall of the square motor, causing the abutting rod 6 to push and compress the abutting spring 61, and the sliding block 81 on the abutting plate 32 slides in the sliding groove 8.

[0057] After the cross connecting frame 34 changes from the abutting rollers 35 at both ends abutting against the side wall of the abrasive belt 36 to the abutting roller 35 at a single end abutting against the side wall of the abrasive belt 36, the abrasive belt 36 is in a slack state due to the lack of part of the support. Since the abrasive belt 36 is in a slack state, the tensioning roller 53 lacks the pulling force of the abrasive belt 36, and under the push of the tensioning spring 52, the tensioning roller 53 moves towards the side close to the abrasive belt 36, causing the tensioning roller 53 to push and tension the abrasive belt 36.

[0058] In this embodiment, when grinding the square motor housing, the cross connecting frame 34 is used to grind the square motor housing. After grinding the side wall of the square motor housing, by driving the cross connecting frame 34 to rotate, one end of the cross connecting frame 34 moves to the installation groove of the square motor housing to grind the installation groove of the square motor housing. Grinding the installation groove of the square motor housing can make the surface treatment quality of the motor housing consistent, and can reduce the time for replacing the grinding tool, thereby improving the grinding efficiency.

[0059] In this embodiment, by centering and clamping the motor housing, the position of the motor housing during grinding can be accurate, reducing the positioning error, ensuring the consistency of the grinding size, and the clamped and fixed motor housing will not move during grinding, thereby improving the stability during grinding and reducing the grinding marks caused by vibration.

[0060] In this embodiment, by driving the abrasive belt 36 to be tensioned, the abrasive belt 36 can better fit on the surface of the workpiece, improving the grinding efficiency, reducing the grinding time, and enabling the abrasive belt 36 to maintain a good working state, reducing the frequency of replacing the abrasive belt 36, and reducing the downtime and replacement cost.

[0061] In the embodiment of the present application, the implementation principle of a grinding device for the housing in motor production is as follows: Place the motor housing on the side of the sliding plate 21 away from the clamping cylinder 22, and start the clamping cylinder 22. Move the output shaft of the clamping cylinder 22 towards the side close to the motor housing. When it moves to a certain extent, the inclined cutting block 23 on the output shaft of the clamping cylinder 22 abuts against the abutting block 25. At this time, the inclined cutting block 23 pushes the abutting block 25 and the clamping block 241 towards the inner wall of the motor housing, so that the inner wall of the motor housing abuts against the clamping block 241. Due to the axial array distribution of the clamping blocks 241, when all the clamping blocks 241 abut against the inner wall of the motor housing, the centering of the motor housing is completed.

[0062] Start the moving motor 26 to rotate the output shaft of the moving motor 26. The rotation of the output shaft of the moving motor 26 drives the moving lead screw 27 to rotate. Due to the threaded connection between the moving lead screw 27 and the sliding plate 21, the moving lead screw 27 can drive the sliding plate 21 to move in the horizontal direction during rotation. When the angle of the motor housing needs to be adjusted, start the rotating motor 28 to rotate the output shaft of the rotating motor 28. The rotation of the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate. The rotation of the rotating gear 29 drives the driven gear 291 to rotate, so that the driven gear 291 drives the clamping cylinder 22 and the clamping plate 24 to rotate, thereby realizing the adjustment of the angle of the motor housing.

[0063] When grinding the side wall of a circular motor, drive the abrasive belt 36 to rotate through the driving motor 71, and start the abutting cylinder 31 to drive the cross connecting frame 34 to move towards the side close to the abrasive belt 36. Rotate the cross connecting frame 34 so that two of the endpoints of the cross connecting frame 34 abut against the inner wall of the abrasive belt 36, and make the abrasive belt 36 at the middle position between the two endpoints of the cross connecting frame 34 abut against the side wall of the circular motor housing. Then, under the drive of the driving motor 71, grind the side wall of the circular motor housing. When grinding the side wall of a square motor, repeat the above operation.

[0064] When grinding the installation groove of a square motor, start the rotating motor 28 to drive the rotating gear 29 to rotate through the output shaft of the rotating motor 28. The rotation of the rotating gear 29 drives the driven gear 291 to rotate. The rotation of the driven gear 291 drives the clamping cylinder 22 to rotate, so that the cross connecting frame 34 changes from two endpoints abutting against the abrasive belt 36 to a single endpoint contacting the abrasive belt 36. After the contact, start the driving motor 71 to drive the abrasive belt 36 to rotate, and grind the installation groove of the square motor through the abrasive belt 36.

[0065] When it is necessary to drive the cross connecting frame 34 to rotate, start the adjustment motor 9 to make the output shaft of the adjustment motor 9 rotate, and drive the connecting shaft 33 to rotate through the way of gear transmission. Since the connecting shaft 33 and the cross connecting frame 34 are rotationally connected, the cross connecting frame 34 cannot be driven to rotate when the connecting shaft 33 starts to rotate. At this time, the adjustment spring 43 at the middle position between the first adjustment block 4 and the second adjustment block 42 is in a compressed state. After rotating to a certain extent, the cross connecting frame 34 is located at the middle position of the installation groove. Then turn off the adjustment motor 9, and make the two side walls of the installation groove push the cross connecting frame 34 to make the cross connecting frame 34 located at the middle position of the installation groove.

[0066] When the abutting rollers 35 at the two end points of the cross connecting frame 34 abut against the side wall of the abrasive belt 36 and are changed to the abutting rollers 35 at a single end point abutting against the side wall of the abrasive belt 36, due to the limitation of the length of the cross connecting frame 34, the abutting plate 32 moves towards the side away from the side wall of the square motor, so that the abutting rod 6 compresses the abutting spring 61, and the sliding block 81 on the abutting plate 32 slides in the sliding groove 8.

[0067] After the abutting rollers 35 at the two end points of the cross connecting frame 34 abut against the side wall of the abrasive belt 36 and are changed to the abutting rollers 35 at a single end point abutting against the side wall of the abrasive belt 36, the abrasive belt 36 lacks a part of support. At this time, the abrasive belt 36 is in a slack state. Since the abrasive belt 36 is in a slack state, the tensioning roller 53 lacks the pulling of the abrasive belt 36. Under the push of the tensioning spring 52, the tensioning roller 53 moves towards the side close to the abrasive belt 36, so that the tensioning roller 53 pushes the abrasive belt 36 to be tightened.

[0068] The above is the preferred implementation mode of the present application. It should be pointed out that for those of ordinary skill in the art of the present technology, without departing from the principle described in the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
