[0032] A retaining ring 11 is arranged at the inner side of the winding drum 1 , and a limiting block 15 is arranged at the upper side of the motor frame 2 .

[0033] A positioning piece 13 is disposed at the inner side of the winding drum 1 , and a positioning groove 19 is disposed at the outer side of the motor frame 2 . The positioning groove 19 is nested and connected with the positioning piece 13 .

[0035] In the present embodiment, a specific implementation step of a motor coil winding tool is as follows: when in use, the stator is placed in the winding cup 5 tool, and then the winding reel 1 is placed on the stator, and the lead-out wire column 4 is fixed to the winding reel 1 with screws. When the height difference caused by the stator replacing the motor frame 2 of different heights is adjusted, the length specification of the lead-out wire column 4 is changed, and at the same time, a groove is opened at the bottom of the winding reel 1 tool, and a rubber strip 14 is placed, and it is clamped and fixed to the winding reel 1 through the bottom of the clamp rod 3, which is also convenient for disassembly and subsequent polishing, grinding and maintenance.

[0036] like Figure 1-5 As shown, a handle 7 is provided at the top of the winding cup 5, clamping rods 3 are respectively provided at the left and right sides of the winding cup 5, fixing holes 6 are respectively provided at the upper and lower sides of the winding drum 1, a limiting rod 9 is provided at the lower position of the clamping rod 3, the winding drum 1 and the winding cup 5 are connected with the clamping rod 3 through the fixing holes 6, and compression springs 12 are respectively provided at the upper and lower sides of the bottom of the winding cup 5, the compression spring 12 is connected to the upper part of the clamping rod 3, a rubber strip 14 is provided at the bottom of the winding drum 1, the winding drum 1 is connected to the rubber strip 14 by snapping, and the lead-out wire column 4 is plug-connected with the winding drum 1.

[0037] Preferably, the setting of the handle 7 makes it more convenient to move and carry the winding cup, and the design of the clamping rod 3 and the limit rod 9 helps to fix and adjust the position of the tooling, thereby improving the convenience of operation. The mutual connection and fixation of the fixing hole 6, the clamping rod 3, the limit rod 9 and the clamping spring 12 and other components can ensure the stability and firmness between the winding reel 1 and the winding cup 5, thereby ensuring the stable winding operation. The setting of the clamping spring 12 and the rubber strip 14 helps to maintain the stability of the tooling and prevent it from loosening.

Through the cooperation between the positioning member 13 and the positioning groove 19, the connection stability between the tooling components can be increased, and position displacement or movement during the winding process can be prevented, thereby ensuring the consistency and quality of the winding and the accuracy of the positioning. It can also make the assembly and disassembly process more convenient and efficient, thereby improving work efficiency. Accurate positioning can effectively reduce the coil winding error caused by position deviation, ensuring that each wound coil has the same specifications and performance.

[0041] Optional, copper wire cable groove 16 design, during the coil winding process, the cable groove 16 can make the copper wire regularly wound, the wound coil will also become neat due to the cable groove 16, and after the cable arrangement is optimized, this skeleton can be used to make products with high slot fill rate. During the coil winding process, the first wire will interfere with the subsequent cable arrangement. The inner side of the skeleton adopts a groove-shaped copper wire avoidance groove 17 design, which can make the dead wire fall into the avoidance groove 17 without affecting the subsequent cable arrangement. At the same time, it also plays a role in fixing the dead wire, and will not cause loose dead wire due to vibration and other conditions. This skeleton is equipped with a binding position 18. Through the wire binding equipment, the motor lead copper wire and the resin skeleton binding are integrated to prevent the lead wire from loosening and shaking, which can effectively reduce the motor noise and make the motor durable.
