During the production process, multiple processing steps are required for the motor end caps, such as drilling, milling, boring, and tapping, in order to meet the precision and performance requirements of motor assembly.

[0003] Currently, after long-term observation and use, it has been found that if the motor end cover is not positioned beforehand during the clamping and processing of the motor end cover, the end cover cannot be in a fixed and precise position during processing. This results in an uncertain position of the tool relative to the end cover, and the dimensions such as the hole diameter and shaft diameter after processing exceed the tolerance range. This leads to problems in subsequent assembly with bearings, machine bases, and other components, and also causes inconsistencies in the position of each end cover on the fixture during batch processing, resulting in differences in the processing of the motor end cover. Therefore, a motor end cover positioning and processing fixture is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides a motor end cap positioning and processing fixture, including a processing table 1; characterized in that: multiple sets of support legs 11 are fixedly connected to the bottom end of the processing table 1; a wrapping frame 12 is fixedly connected to the inner side wall of the processing table 1; a motor 13 is fixedly connected to the inner side wall of the wrapping frame 12; a rotating rod 14 is provided at the output end of the motor 13; a motor mounting plate 15 is fixedly connected to the top end of the motor 13; the rotating rod 14 is rotatably connected to the side wall of the motor mounting plate 15; an assembly plate 16 is detachably connected to the inner side wall of the motor mounting plate 15; multiple sets of guide grooves 17 are opened on the side wall of the assembly plate 16; the guide grooves 17 are arranged in a circumferential array; a filling groove 18 is opened on the side wall of the assembly plate 16; and a filling groove 18 is fixedly connected to the side wall of the filling groove 18. A ring-shaped tension spring 19 is included; a slider 101 is slidably connected to the side wall of the guide groove 17; a fastening groove 102 is provided on the side wall of the slider 101; the ring-shaped tension spring 19 is placed in the fastening groove 102; a clamping block 103 is slidably connected to the inner side wall of the slider 101; an adjusting groove 104 is provided on the side wall of the clamping block 103; a first spring assembly 105 is fixedly connected to the side wall of the adjusting groove 104; a positioning pin 106 is fixedly connected to the end of the first spring assembly 105; the positioning pin 106 is slidably connected to the side wall of the adjusting groove 104; a support plate 107 is placed on the side wall of the clamping block 103; a ten-pointed cam 108 is fixedly connected to the end of the rotating rod 14; and a bearing 109 is rotatably connected to the side wall of the slider 101.During operation, the motor 13 is first started to drive the rotating rod 14 to rotate according to the set angle of the protrusion of the decagonal cam 108, thereby driving the decagonal cam 108 to rotate. During the rotation of the decagonal cam 108, when the protrusion of the decagonal cam 108 contacts the bearing 109, the bearing 109 transmits the pushing force of the decagonal cam 108 to the slider 101. At this time, the slider 101 moves. Because the guide groove 17 and the support plate 107 restrict the movement trajectory of the slider 101, the slider 101 can only move outward in the direction of the guide groove 17. During horizontal movement, as the slider 101 moves outward, each group of sliders 101 drives the annular tension spring 19 connected to its respective fastening groove 102 to perform a stretching motion. Through the joint movement of each group of sliders 101, the effective diameter of the slider 101 can be expanded. At this time, after the motor end cover is placed on the support plate 107, the motor 13 drives the rotating rod 14 to reverse. At this time, with the rotation of the ten-corner cam 108, the pushing force of the protrusion of the ten-corner cam 108 on each group of sliders 101 is reduced, thereby allowing the slider 101 to return to its original sliding position. During the process, the positioning pin 106 is limited by the height of the motor end cover surface and is retracted into the adjusting groove 104 by the first spring assembly 105. Since the edge of the motor end cover is provided with a cylindrical hole, when the positioning pin 106 slides to the cylindrical hole of the motor end cover, the first spring assembly 105 can drive the positioning pin 106 to insert into the cylindrical hole of the motor end cover. By positioning the cylindrical hole at the edge of the motor end cover, the horizontal movement and rotational freedom of the end cover can be restricted, thereby positioning and fixing the motor end cover. When the ten-corner cam 108 rotates and the bearing 10... During the contact process, the rotatable bearing 109 allows for adjustment of the thrust force generated at the protrusion of the ten-corner cam 108, thereby improving the stability of the thrust force. This design, through the engagement of the locating pin and the cylindrical hole on the end cover, accurately determines the position of the motor end cover in the fixture, restricting the end cover's degrees of freedom in multiple directions. This ensures the end cover remains in a fixed and precise position during processing, reducing product quality variations caused by inaccurate positioning, guaranteeing high consistency of the processed end cover, and improving the overall product quality and interchangeability.

[0027] Furthermore, such as Figure 4As shown, the clamping block 103 has symmetrically formed fixing grooves 2 on its sidewalls; a hydraulic damper 21 is fixedly connected to the sidewall of the fixing groove 2; a second spring assembly 22 is fixedly connected to the sidewall of the fixing groove 2; a connecting sleeve 23 is fixedly connected to the output end of the hydraulic damper 21; the connecting sleeve 23 is slidably connected to the sidewall of the fixing groove 2; the second spring assembly 22 and the connecting sleeve 23 are fixedly connected; a flexible clamping plate 24 is fixedly connected to the end of the connecting sleeve 23; during operation, when the cylindrical hole at the edge of the motor end cover is fixed by the positioning pin 106, the flexible clamping plate 24 fixed to each set of clamping blocks 103 can contact the motor end cover and perform a clamping function, depending on different The shape of the cylindrical hole edge of the motor end cover varies. The buffering effect of the hydraulic damper 21 and the second spring assembly 22 can buffer and adjust the connecting sleeve 23, thereby adapting it to the shape and length of the cylindrical hole edge. At the same time, since the flexible clamping plate 24 is deformable, it can enhance the contact area with the cylindrical hole edge, thereby improving the clamping force. This design allows the flexible clamping plate to be adaptively adjusted according to the different edge shapes of the cylindrical hole at the motor end cover, making it adaptable to the edge of the motor end cover with different shapes, sizes and specifications, increasing the contact area with the edge of the motor end cover, and thus improving the overall clamping force of the motor end cover.

[0028] Furthermore, such as Figure 4 As shown, the slider 101 has a disassembly groove 3 on its side wall; the clamping block 103 has an insertion groove 31 on its side wall; both the disassembly groove 3 and the insertion groove 31 have a pull groove 32 slidably connected to their side walls; a plug rod 33 is fitted onto the side wall of the pull groove 32; the plug rod 33 is fixedly connected to the side wall of the disassembly groove 3; during operation, by pulling out the pull groove 32 to make it slide out of the insertion groove 31, the pin fixing effect on the clamping block 103 can be released. During the pulling process, the plug rod 33 will be compressed. When the clamping block 103 inserts into the slider... When the clamp 103 is engaged, releasing the pull groove 32 allows the pull groove 32 to slide into the embedding groove 31 through the rebound force of the insert rod 33, thus fixing the clamp 103 with a pin. This completes the flexible disassembly and fixing operation of the clamp 103. This design, through the flexible disassembly and fixing setting of the clamp 103, allows the clamp to be quickly removed from the fixture when the clamps are worn, damaged, or need to be replaced with different types of clamps to adapt to different workpieces. This flexible disassembly operation saves time by eliminating the need for complicated tools or cumbersome steps.

[0029] Furthermore, such as Figure 3As shown, a collection tray 4 is slidably placed on the side wall of the support plate 107; an outlet groove 41 is opened on the side wall of the collection tray 4; during operation, by setting the collection tray 4 at the bottom of the motor end cover, and the height setting of the collection tray 4 does not affect the processing, the collection tray 4 can collect the chips and debris generated during the processing of the motor end cover. This design can reduce the accumulation of chips and debris and improve the collection efficiency by collecting the chips and debris generated during the processing of the motor end cover.

[0030] Furthermore, such as Figure 3 As shown, a filter disc 5 is fixedly connected to the inner wall of the collection disc 4. During operation, when various processing steps are performed on the motor end cover, the chips that fall off will fall into the collection disc 4. At this time, the filter disc 5 can isolate the larger chips and allow the smaller chips and debris to fall into the collection disc 4. This design isolates and collects the chips and debris generated during the processing of the motor end cover by shape and size, reducing the need for subsequent separation of larger chips and debris, and improving recycling efficiency and speed.

[0031] Furthermore, such as Figure 4 As shown, the flexible clamping plate 24 has a rubber sheet 6 on its side wall. During operation, when the flexible clamping plate 24 clamps the edge of the motor end cover, the rubber sheet 6 enhances the friction between the motor end cover and the clamping plate. This design improves the clamping and positioning stability of the motor end cover by enhancing the friction between the clamping plate and the motor end cover.

[0032] Furthermore, such as Figure 1 As shown, a suction cup seat 7 is provided at the bottom of the support leg 11; during operation, the suction cup seat 7 can generate suction between the support leg and the ground, thereby improving the stability between the support leg and the ground. This design enhances the stability between the support leg and the ground, thereby improving the stability effect when processing the motor end cover.

[0033] Working principle: First, the motor 13 is started, driving the rotating rod 14 to rotate according to the set angle of the protrusion of the decagonal cam 108. This, in turn, drives the decagonal cam 108 to rotate. During the rotation of the decagonal cam 108, when the protrusion of the decagonal cam 108 contacts the bearing 109, the bearing 109 transfers the pushing force of the decagonal cam 108 to the slider 101. At this time, the slider 101 moves. Because the guide groove 17 and the support plate 107 restrict the movement trajectory of the slider 101, the slider 101 can only move horizontally outward in the direction of the guide groove 17. During the outward movement of the slider 101, each group of sliders 101 will drive the annular tension spring 19 connected to its respective fastening groove 102 to perform a stretching motion. The combined movement of each set of sliders 101 expands the effective diameter of the sliders 101. When the motor end cover is placed on the support plate 107, the motor 13 drives the rotating rod 14 to reverse. As the decagonal cam 108 rotates, the pushing force exerted on each set of sliders 101 by the protrusion of the decagonal cam 108 is reduced, causing the sliders 101 to return to their original position. During this process, the positioning pin 106, limited by the height of the motor end cover surface, is retracted into the adjusting groove 104 by the first spring assembly 105. Since the motor end cover has a cylindrical hole on its edge, when the positioning pin 106 slides to the cylindrical hole of the motor end cover, the first spring assembly 105 drives the positioning pin 106 to insert into the cylindrical hole of the motor end cover. This allows the motor end cover to return to its original position. The cylindrical holes on the edge of the motor end cover serve a positioning function, thereby restricting the horizontal movement and rotational freedom of the end cover, thus positioning and fixing the motor end cover. During the rotation of the ten-corner cam 108 and its contact with the bearing 109, the rotatability of the bearing 109 allows for adjustment of the thrust force generated at the protrusion of the ten-corner cam 108, thereby improving the stability of the thrust force. During the pinning and fixing of the cylindrical holes at the edge of the motor end cover by the positioning pin 106, the flexible clamping plates 24 fixed to each set of clamping blocks 103 can contact the motor end cover and perform a clamping function. Depending on the shape of the cylindrical hole edge of different motor end covers, the hydraulic damper 21 and the buffering adjustment effect of the second spring assembly 22 can provide a buffering effect on the connecting sleeve 23. The clamping mechanism adjusts to accommodate different cylindrical hole edge shapes and lengths. The flexible clamping plate 24, being deformable, enhances the contact area with the cylindrical hole edge, thus increasing clamping force. Pulling out the pulling groove 32 allows it to slide out of the embedding groove 31, releasing the pin fixing effect on the clamping block 103. During the pulling process, the insert rod 33 is compressed. When the clamping block 103 inserts into the slider 101, releasing the pulling groove 32 allows the rebound force of the insert rod 33 to drive the pulling groove 32 into the embedding groove 31, fixing the clamping block 103 with the pin. This completes the flexible disassembly and fixing operation of the clamping block 103. A collecting tray 4 is provided at the bottom of the motor end cover, and the height of the collecting tray 4 does not affect the processing.The collection tray 4 collects chips and debris generated during the processing of the motor end cover. During various processing steps on the motor end cover, chips fall into the collection tray 4. The filter tray 5 separates larger chips, allowing smaller chips and debris to fall into the collection tray 4. When the flexible clamping plate 24 holds the edge of the motor end cover, the rubber sheet 6 enhances the friction between the clamping plate and the end cover, and the suction cup seat 7 generates suction with the ground, thus improving stability.
