Description
Technical Field
[0001] This utility model relates to the field of motor stator coil winding technology, and in particular to a winding tool for stator core winding. Background Technology
[0002] Motors are classified as either internally rotating or externally rotating. In an internally rotating motor, the rotating parts are located on the inside, while the stationary parts are on the outside. The stator coils are typically inside a stamped stator core, with copper wire wound around the teeth of the stator core using a specific method. This process can generally be divided into manual winding and machine winding; machine winding (hereinafter referred to as machine winding) is more efficient and less expensive. For machine winding of stator cores in internal rotary motors, there are requirements regarding the length of the lead wire (limited by the required three-phase wire length and wiring method of the stator coil). Therefore, during machine winding, after winding a certain number of teeth, the wire is usually trimmed manually (involving labor and high cost) or the machine is rotated a certain number of times to leave sufficient wire length. When the required lead wire length is very long, the number of machine rotations is also large. After winding one coil, due to the large number of copper coils, copper wire may slip out of the hanging pin at the hanging pin, thus affecting the efficiency of machine winding. Furthermore, due to the presence of the machine winding nozzle, the hanging pin cannot be made very long. Therefore, we propose a winding fixture for stator core winding to solve the above problems.

[0026] The working principle of the winding fixture for stator core winding mentioned in this utility model: In use, by installing the second hanging pin 320 onto the surface of the winding base 110, the copper wire 330 can be constrained at multiple points. When winding, the cylinder 326 on the second hanging pin 320 can be rotated downwards at 90°, so that the second hanging pin 320 and the cylinder 326 can form a "7" shape, thereby preventing the copper wire wrapped around the second hanging pin 320 from slipping out. After winding is completed, the cylinder 326 on the second hanging pin 320 can be rotated upwards at 90°, so that the second hanging pin 320 and the cylinder 326 can form a "1" shape, thereby easily removing the wound copper wire and improving the winding efficiency of the machine. Meanwhile, the circular boss 321 on the second hanging pin 320 is embedded into the second blind hole 113, making the second hanging pin 320 and the winding base 110 a detachable structure, which makes the second hanging pin 320 easy to install and remove. The second hanging pin 320 can be installed or removed at will according to the required quantity. Then, the first wire-hanging pin 310 can be used to tighten the wire when winding between the teeth of the stator core 200, and the first wire-hanging pin 310 is installed into the first blind hole 112 through the bottom of the first wire-hanging pin 310, so that the first wire-hanging pin 310 is a detachable structure.
[0027] Then, by installing the positioning block 140 into the inner diameter notch concave surface 116 and adapting the arc-shaped protrusion 141 into the pin groove 210, the stator core 200 can be circumferentially limited and fixed, and the stator core 200 can move during winding.
[0028] Then, by installing the pad 130 inside the inner diameter 114, the stator core 200 installed inside the inner diameter 114 can be raised so that one end of the stator core 200 is at the same level as the surface of the winding base 110.
