Furthermore, for stators of different diameters, specialized limiting devices are often required. This not only increases equipment investment costs but also makes equipment changeover time-consuming during production, severely impacting production efficiency and the company's economic benefits.

[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. This utility model uses a motor to rotate a first gear, which in turn rotates an L-shaped rod via a meshing second gear. The L-shaped rod then rotates a winding drum. Rotating a first handwheel rotates a first lead screw, which in turn moves a threaded moving block. Rotating a second handwheel rotates a transmission rod, which in turn rotates a round rod via a combination of a first and second bevel gear. The round rod then rotates the drum. The winding direction can be adjusted by rotating the motor in both directions, and the rotation of the drum allows for flexible adjustment of the winding span to meet different winding requirements.
[0012] 2. This new type of device rotates by rotating the third handwheel to drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the threaded slider to move closer to each other. The slider drives the arc plates on both sides to move further apart through the connecting rod. At the same time, the telescopic rod is extended, thereby adapting to stators with different inner ring diameters and improving the versatility of the device. Attached Figure Description

A movable block 10 is screwed to the outside of the first lead screw 9. A U-shaped frame 11 is fixedly connected to the top of the movable block 10. A vertical plate 12 is fixedly connected inside the U-shaped frame 11. A transmission rod 17 is rotatably connected inside the vertical plate 12. A first bevel gear 13 is fixedly connected to one end of the transmission rod 17. A round rod 14 is rotatably connected inside the U-shaped frame 11. A second bevel gear 15 that meshes with the first bevel gear 13 is fixedly sleeved on the outside of the round rod 14. The top end of the round rod 14 extends through to the top of the U-shaped frame 11 and is provided with a limiting mechanism 16.
[0021] The limiting mechanism 16 includes a cylinder 1601, which is fixedly installed at the top of the round rod 14. A bidirectional lead screw 1602 is rotatably connected inside the cylinder 1601. The top of the bidirectional lead screw 1602 extends through to the top of the cylinder 1601 and is fixedly connected to a third handwheel 1603. Slider blocks 1604 are threadedly connected to both sides of the bidirectional lead screw 1602. Connecting rods 1605 are rotatably connected to both sides of the two sliders 1604. The two connecting rods 1605 extend through to the outside of the cylinder 1601 on the opposite side and are fixedly connected to an arc plate 1606. Telescopic rods 1607 are fixedly connected to the top and bottom of the corresponding sides of the two arc plates 1606. One side of the telescopic rod 1607 is fixedly connected to the cylinder 1601.
[0022] Rotating the third handwheel 1603 will drive the arc plates 1606 on both sides to open and close through the transmission of the two-way lead screw 1602, slider 1604, and connecting rod 1605.
[0023] One end of the first lead screw 9 extends through to the outside of the support frame 8 and is fixedly connected to the first handwheel 18.

Then, the copper wire spool is fitted onto the outside of the support column 21, and the copper wire is passed through the winding spool 7 and fixed to the stator. Rotating the first handwheel 18 drives the first screw 9 to rotate. 9 drives the threaded moving block 10 to move, adjusting the stator position. Rotating the second handwheel 19 drives the transmission rod 17 to rotate. The transmission rod 17 drives the round rod 14 to rotate through the cooperation of the first bevel gear 13 and the second bevel gear 15. The round rod 14 drives the cylinder 1601 to rotate, adjusting the winding span. The rotation of the motor 3 drives the first gear 4 to rotate. The first gear 4 drives the L-shaped rod 6 to rotate through the meshing second gear 5. The L-shaped rod 6 drives the winding cylinder 7 to rotate. The stator is wound through the cooperation of the guide frame 22 and the guide block 20. The reverse motor 3 can be used to wind in the opposite direction.
