Description

TECHNICAL FIELD

[0001] The utility model relates to a winding equipment field, especially a winding shaft quick threading structure. BACKGROUND

[0002] In the winding equipment, with the miniaturization of stator (of course also has some requirements special stator) therefore so as to realize corresponding inductance, the diameter of enameled wire is also required to be smaller, then the hardness of enameled wire will reduce accordingly.

[0003] Therefore, in the actual wire guiding process, it is also difficult to guide the enameled wire to the position of the flying fork, the existing design is to set the whole wire guide tube to a smaller inner diameter, thereby achieving the stable guiding of the enameled wire with small diameter or low hardness, and the threading process is more troublesome, especially the end of the wire guide tube is provided with a bending area, so the threading process needs to spend more time.

[0004] Then there is also a design of winding the enameled wire by using a wire guide tube with a larger inner diameter (for example, Chinese patent CN202220103626.5, the wire guide tube is integrally provided), because the wire diameter is smaller, when the inner diameter of the wire guide tube exceeds the preset value, the problems of flying fork jumping or wire breakage often occur (the main factor is that the guide seat is relatively slidably arranged on the main shaft, so a gap is generated between the two wire guide tubes, so the general method is to reduce the winding speed to improve the stability). SUMMARY

[0005] The main purpose of the utility model is to provide a winding shaft quick threading structure, which aims to improve the structure of the wire guide tube and facilitate the threading of the enameled wire with small wire diameter while ensuring the stability of the wire conveying.

[0007] A rack is provided with a pivotally arranged main shaft, the main shaft is provided with a main pipe deviating from the shaft center, and the main pipe is provided with a wire guiding cavity;

[0008] A wire seat is slidably installed at the rear end position of the main shaft, the wire seat is provided with a wire guide tube matched with the main pipe, and the outer diameter of the wire guide tube is matched with the inner diameter of the main pipe.

[0009] The wire guide tube can slide between the position of extending into the wire guiding cavity and the position of withdrawing from the wire guiding cavity.

[0010] In the actual winding process, the wire seat can rotate with the main shaft, the wire seat can slide along the length direction of the main shaft, and the tightness of the enameled wire can be adjusted.

[0011] The present integrated wire passing pipe is divided into a main pipe and a wire pipe, the outer diameter of the wire pipe is adapted to the inner diameter of the main pipe, that is, a small pipe is sleeved with a large pipe, so that the coil of the enameled wire can be stably conveyed at the end, the looseness caused by the too large inner diameter of the wire passing pipe is avoided, the stability of the conveying is ensured, at the same time, the length of the wire pipe is short, so that the wire pipe can be directly threaded, the main pipe can adopt a conventional threading device (such as the cooperation of two balls and the wire body as shown in the figure), which is convenient for threading and ensures the stability of the wire conveying.
