The stator winding of a motor is usually composed of multiple coils, and each coil is wound by many turns of wire. These coils are arranged on the stator of the motor according to a certain rule to form different numbers of magnetic pole pairs and phases. When the existing stator winding of a motor is offline, the winding is manually held and sleeved on the stator of the motor.

Wearing gloves will reduce the flexibility of the installation and affect the quality and efficiency of the winding offline. To this end, the utility model proposes a mechanism for offline winding of the stator winding of a motor. Utility Model Content

[0028] like Figure 2 and Figure 3 As shown, the downline assembly 3 includes a connecting frame 31 arranged at the output end of the first cylinder 2, and the connecting frame 31 is a "cross" structure. A fixing ring 32 is fixedly provided on one side of the connecting frame 31, which can be stably connected to the fixing ring 32. A rotating groove 33 is opened on the side wall of the fixing ring 32. A ring 34 is movably sleeved in the rotating groove 33, which can make the ring 34 rotate stably. A toothed ring 35 is fixedly sleeved on the outer wall of the ring 34, and a limiting assembly 36 for positioning the winding is fixedly provided on the inner wall of the ring 34, which can position the stator windings of motors of different lengths to improve practicality.

[0029] Furthermore, the downline assembly 3 also includes a support frame 37, which is fixedly arranged on one side of the fixed ring 32. A first motor 38 is fixedly installed on the support frame 37, and the first motor 38 is a servo motor. A gear 39 is fixedly arranged at the output end of the first motor 38, which can transmit the rotation of the sleeve ring 34 and accurately adjust the angle of the limit assembly 36.

[0030] Furthermore, the limiting assembly 36 includes a fixing frame 361 fixedly arranged on the inner wall of the fixing ring 32, a second motor 362 is fixedly installed on one side of the fixing frame 361, a threaded rod 363 is fixedly arranged on the output end of the second motor 362, the threaded rod 363 is rotatably arranged between the fixing frame 361 through a bearing, and a sleeve block 364 is movably sleeved on the outer wall of the fixing frame 361, and the sleeve block 364 is threadedly sleeved with the threaded rod 363, so that the sleeve block 364 can slide stably, and one end of the sleeve block 364 is fixed An outer sleeve rod 365 is fixedly connected thereto, and the interior of the outer sleeve rod 365 is hollow. A first clamping rod 366 is fixedly connected to one side of the outer sleeve rod 365. A sleeve connecting rod 367 is movably sleeved on one end of the outer sleeve rod 365, and the sleeve connecting rod 367 is a "U"-shaped structure. A second clamping rod 368 is fixedly connected to one side of the sleeve connecting rod 367. A second cylinder 369 is fixedly installed on the outer sleeve rod 365, and the output end of the second cylinder 369 is fixedly connected to the second clamping rod 368, which can stably and tightly support the stator winding of the motor.

[0031] like Figure 4As shown in the figure, the clamping assembly 4 includes a frame 41 fixedly arranged on the support base 1. A fixed clamping plate 42 is fixedly arranged on the frame 41 through a mounting seat. A third cylinder 43 is arranged through the top of the frame 41. The output end of the third cylinder 43 is fixedly provided with a movable clamping plate 44, and the movable clamping plate 44 is located directly above the fixed clamping plate 42, which can clamp motor stators of different sizes and improve the stability of positioning.

[0032] Secondly, the support base 1 and the frame 41 are arranged in a "U" - shaped structure, which has good stability.

[0033] Finally, protective pads are arranged on the opposite surfaces of the fixed clamping plate 42 and the movable clamping plate 44, and the protective pads are made of rubber material, which can increase the friction force with the outer wall of the motor stator, make the clamping more stable, and avoid scratching at the same time.

This can accurately control the position and angle of the winding offline, ensure the accuracy and consistency of the winding offline, and avoid the risk of hand scratches during manual operation, thereby improving work safety and ensuring the quality and stability of the winding offline.
