Description
Technical Field
[0001] This utility model relates to the field of motor coil winding technology, specifically a positioning tool for motor coil winding processing. Background Technology
[0002] In motor production, coil winding is a critical process, and its winding accuracy directly affects motor performance. Traditional winding relies on manual positioning or simple tooling, which can easily lead to loose windings and misalignment between layers due to coil position deviation and uneven winding tension, resulting in loud noise, low efficiency, or even burnout during motor operation.
[0003] Existing positioning fixtures are mostly adapted to a single model of motor, which has poor versatility. Changing the model requires re-adjustment, which increases the production cycle and cost. At the same time, manual positioning is time-consuming and labor-intensive, which is difficult to meet the accuracy and efficiency requirements of large-scale production. Therefore, it is necessary to develop a dedicated positioning fixture to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a positioning fixture for motor coil winding processing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning fixture for motor coil winding processing, comprising a worktable, a coil winding mechanism provided on the surface of the worktable, the coil winding mechanism comprising a bobbin fixing component and a winding component, and an auxiliary mechanism provided on the surface of the worktable;
[0006] The winding assembly includes a fixing block fixedly connected to the center of the right end of the top of the workbench. Connecting plates are fixedly connected to the front and rear ends of the top of the fixing block. A rotating shaft is rotatably connected to the surface of the connecting plates. A first servo motor is installed inside the connecting plates. A fixing frame is fixedly connected to the outer end of the rotating shaft. A bidirectional screw is rotatably connected to the inner end of the fixing frame. A second servo motor is installed on the right end of the fixing frame. A slide is provided on the surface of the bidirectional screw. A threaded post is fixedly connected to the surface of the slide. A winding cylinder is provided on the surface of the threaded post. A baffle is fixedly connected to the surface of the winding cylinder. A limit nut is provided on the surface of the threaded post. The bidirectional screw is driven by the second servo motor. It can move the slide and threaded column left and right to adjust the position of the winding cylinder and adapt to the width requirements of different coil windings. The slides at both ends of the bidirectional screw surface can move synchronously in opposite directions to ensure uniform coil distribution during winding and improve winding accuracy. The winding cylinder is fixed by the threaded column and the limit nut. Loosening the limit nut allows for quick replacement of winding cylinders of different specifications to meet diverse coil production needs. The baffle can effectively limit the coil winding range, prevent the wire from falling off during winding, and ensure the coil shape is regular. The first servo motor drives the fixed frame to rotate through the rotating shaft, providing stable power for winding. The precise control of the first servo motor can achieve accurate control of the number of coils wound.
[0007] Preferably, the rotating shaft is fixedly connected to the output end of the first servo motor, and the bidirectional screw is fixedly connected to the left output end of the second servo motor.
[0008] Preferably, the second servo motor is threaded to the left and right ends of the bidirectional screw surface, and the limiting nut is threaded to the surface of the threaded column.
[0009] Preferably, the bobbin fixing assembly includes a fixing plate, which is fixedly connected to the front and rear ends of the left side of the top of the workbench. A support column is fixedly connected to the outer end of the fixing plate, and a spring column is fixedly connected to the surface of the support column. A rubber pad is fixedly connected to the surface of the spring column, and a bobbin is installed on the surface of the support column. The spring column on the surface of the support column has elastic expansion and contraction characteristics, which, together with the rubber pad, can tightly fit the inner wall of the bobbin. This can achieve a stable fixation for bobbins of different diameters, preventing the bobbin from shaking during winding. The rubber pad increases the friction with the bobbin, further improving the fixing effect, while preventing damage to the surface of the bobbin due to compression. The elastic design of the spring column makes the installation and removal of the bobbin simple, without the need for complicated tools, saving time for replacing bobbins and improving production efficiency. The stable fixation of the bobbin can ensure that the wire is output evenly during the winding process, reduce the tension fluctuation of the wire caused by the bobbin shaking, avoid wire breakage or loosening, and ensure the quality of coil winding.
[0010] Preferably, the auxiliary mechanism includes a fixed frame, which is fixedly connected to the middle section of the top of the workbench. A first electrically controlled lifting column is installed at the front and rear ends of the top left end of the inner end of the fixed frame. A cleaning brush is installed at the bottom end of the first electrically controlled lifting column. A second electrically controlled lifting column is installed at the front and rear ends of the top right end of the inner end of the fixed frame. A cutting blade is installed at the bottom end of the second electrically controlled lifting column.
[0011] Preferably, the workbench is fixedly connected to a base at its four corners, and the top right end of the workbench has through openings at both the front and rear ends.
[0012] Compared with the prior art, this utility model provides a positioning fixture for motor coil winding, which has the following advantages:
[0013] 1. The positioning fixture for motor coil winding is equipped with a winding assembly.

The slides at both ends of the bidirectional screw can move synchronously in opposite directions to ensure uniform coil distribution during winding and improve winding accuracy. The winding cylinder is fixed by the threaded post and limit nut. Loosening the limit nut allows for quick replacement of winding cylinders of different specifications to meet diverse coil production needs. The baffle effectively limits the coil winding range, prevents wires from falling off during winding, and ensures a regular coil shape. The first servo motor drives the fixed frame to rotate through the shaft, providing stable power for winding. The precise control of the first servo motor enables accurate control of the number of coils wound.
[0014] 2. The positioning fixture for motor coil winding is equipped with a spool fixing component. The spring column on the support surface has elastic expansion and contraction characteristics. Together with the rubber pad, it can tightly fit the inner wall of the spool, achieving a stable fixation for spools of different diameters and preventing the spool from shaking during winding. The rubber pad increases the friction with the spool, further improving the fixing effect, while preventing damage to the spool surface due to compression. The elastic design of the spring column makes the installation and removal of the spool simple, requiring no complicated tools, saving time for spool replacement, improving production efficiency, and ensuring stable fixing of the spool. This ensures uniform output of the conductor during winding, reduces tension fluctuations caused by spool shaking, prevents conductor breakage or loosening, and guarantees the quality of coil winding.

[0024] This utility model provides the following technical solution:
[0025] Example 1
[0026] Please see Figure 1-5 A positioning fixture for motor coil winding processing includes a worktable 1, a coil winding mechanism 4 is provided on the surface of the worktable 1, the coil winding mechanism 4 includes a bobbin fixing component 41 and a winding component 42, and an auxiliary mechanism 5 is provided on the surface of the worktable 1.
[0027] The winding assembly 42 includes a fixing block 421, which is fixedly connected to the center of the right end of the top of the workbench 1. Connecting plates 422 are fixedly connected to the front and rear ends of the top of the fixing block 421. A rotating shaft 423 is rotatably connected to the surface of the connecting plate 422. A first servo motor 424 is installed inside the connecting plate 422. A fixing frame 425 is fixedly connected to the outer end of the rotating shaft 423. A bidirectional screw 426 is rotatably connected to the inner end of the fixing frame 425. A second servo motor 427 is installed on the right end of the fixing frame 425. A slide block 428 is provided on the surface of the bidirectional screw 426. A threaded post 429 is fixedly connected to the surface of the slide block 428. A winding cylinder 4201 is provided on the surface of the threaded post 429. A baffle 4202 is fixedly connected to the surface of the winding cylinder 4201. A limit nut 4203 is provided on the surface of the threaded post 429. The bidirectional screw 426 is driven by the second servo motor 427. The rod 426 can drive the slide block 428 and the threaded column 429 to move left and right, thereby adjusting the position of the winding cylinder 4201 to adapt to the width requirements of different coil windings. The slide blocks 428 at both ends of the surface of the bidirectional screw 426 can move synchronously in opposite directions to ensure uniform coil distribution during winding and improve winding accuracy. The winding cylinder 4201 is fixed by the threaded column 429 and the limit nut 4203. Loosening the limit nut 4203 allows for quick replacement of winding cylinders 4201 of different specifications to meet diverse coil production needs. The baffle 4202 can effectively limit the coil winding range, prevent the wire from falling off during winding, and ensure the coil shape is regular. The first servo motor 424 drives the fixed frame 425 to rotate through the rotating shaft 423, providing stable power for winding. The precise control of the first servo motor 424 can achieve precise control of the number of coils wound.
[0028] The rotating shaft 423 is fixedly connected to the output end of the first servo motor 424, and the bidirectional screw 426 is fixedly connected to the left output end of the second servo motor 427.
[0029] The second servo motor 427 is threaded to the left and right ends of the surface of the bidirectional screw 426, and the limit nut 4203 is threaded to the surface of the threaded post 429;
[0030] The spool fixing assembly 41 includes a fixing plate 411, which is fixedly connected to the front and rear ends of the left side of the top of the workbench 1. A support column 412 is fixedly connected to the outer end of the fixing plate 411. A spring column 413 is fixedly connected to the surface of the support column 412, and a rubber pad 414 is fixedly connected to the surface of the spring column 413. A spool 415 is mounted on the surface of the support column 412. The spring column 413 on the surface of the support column 412 has elastic expansion and contraction characteristics, and can fit tightly against the inner wall of the spool 415 in conjunction with the rubber pad 414, so as to achieve a stable fixation for spools 415 of different diameters. To prevent the spool 415 from shaking during winding, the rubber pad 414 increases the friction with the spool 415, further improving the fixing effect. At the same time, it avoids damage to the surface of the spool 415 due to compression. The elastic design of the spring column makes the installation and removal of the spool 415 simple, without complicated tools, saving time for replacing the spool 415 and improving production efficiency. The stable fixing of the spool 415 can ensure that the wire is output evenly during the winding process, reduce the tension fluctuation of the wire caused by the shaking of the spool 415, avoid wire breakage or loosening, and ensure the quality of coil winding.
[0031] Example 2
[0032] Please see Figure 1-5 Furthermore, based on Embodiment 1, the auxiliary mechanism 5 includes a fixed frame 51, which is fixedly connected to the top middle section of the workbench 1. A first electrically controlled lifting column 52 is installed at the front and rear ends of the top left end of the inner end of the fixed frame 51. A cleaning brush 53 is installed at the bottom end of the first electrically controlled lifting column 52. A second electrically controlled lifting column 54 is installed at the front and rear ends of the top right end of the inner end of the fixed frame 51. A cutting blade 55 is installed at the bottom end of the second electrically controlled lifting column 54.
[0033] The workbench 1 has bases 2 fixedly connected to the four corners at the bottom, and through openings 3 are provided at the front and rear ends of the right top of the workbench 1.
[0034] In actual operation, when this device is used, a winding cylinder 4201 of appropriate size is placed on the surface of the threaded post 429 according to the work requirements, and fixed by the limiting nut 4203. Then, a suitable wire spool 415 is placed on the surface of the support post 412 for installation. Then, the first turn of cable is manually wound onto the surface of the winding cylinder 4201, and the winding assembly 42 is started to perform the winding process.
[0035] The second servo motor 427 drives the bidirectional screw 426, which can move the slide 428 and the threaded column 429 left and right to adjust the position of the winding cylinder 4201 to adapt to the width requirements of different coil windings. The slides 428 at both ends of the surface of the bidirectional screw 426 can move in opposite directions synchronously to ensure uniform coil distribution during winding and improve winding accuracy. The winding cylinder 4201 is fixed by the threaded column 429 and the limiting nut 4203. Loosening the limiting nut 4203 allows for quick replacement of winding cylinders 4201 of different specifications to meet diverse coil production needs. The baffle 4202 can effectively limit the coil winding range, prevent the wire from falling off during winding, and ensure the coil shape is regular. The first servo motor 424 drives the fixed frame 425 to rotate through the rotating shaft 423, providing stable power for winding. The precise control of the first servo motor 424 can achieve precise control of the number of coils wound.
[0036] The spring post 413 on the surface of the support post 412 has elastic expansion and contraction characteristics. Together with the rubber pad 414, it can fit tightly against the inner wall of the spool 415, which can achieve a stable fixation for spools 415 of different diameters, preventing the spool 415 from shaking during winding. The rubber pad 414 increases the friction with the spool 415, further improving the fixing effect, while avoiding damage to the surface of the spool 415 due to compression. The elastic design of the spring post makes the installation and disassembly of the spool 415 simple, without complicated tools, saving time for replacing the spool 415 and improving production efficiency. The stable fixation of the spool 415 can ensure that the wire is output evenly during the winding process, reduce the tension fluctuation of the wire caused by the shaking of the spool 415, avoid wire breakage or loosening, and ensure the quality of coil winding.
[0037] During the winding process, the first electrically controlled lifting column 52 can be controlled to lower the cleaning brush 53 to clean the coil and prevent residual dust on the surface from affecting the quality of the coil. After the winding is completed, the second electrically controlled lifting column 54 can be controlled to lower the cutting blade 55 to cut the coil, thus completing the processing work.
