Description

Technical Field

[0001] This utility model belongs to the field of torsion cylinder technology, specifically relating to a self-cleaning mechanism for torsion cylinders. Background Technology

[0002] In the field of motor stator manufacturing, the torsion cylinder is a key piece of equipment for forming the stator end windings. Its core function is to twist and deform the stator end leads, which have already been fitted with pins, in an alternating "outer layer first, then inner layer" sequence, so that the winding ends form a regular radial structure that meets insulation and heat dissipation requirements. In existing technology, the torsion cylinder is usually connected to a Z-axis drive mechanism. During operation, the Z-axis descends continuously and uniformly, while the torsion disc moves sequentially from the outside to the inside according to a preset program, maintaining a specific synchronous relationship with the Z-axis descent, thereby achieving precise torsion of different layers of leads.

[0003] However, this torsion forming process has a significant technical drawback: copper slag remains inside the torsion cylinder during operation. This copper slag mainly originates from metal fragments generated by friction and scraping during the torsion deformation of the leads. Due to the complex internal structure of the torsion cylinder, with numerous fitting gaps and dead corners, these fine copper slags are difficult to completely remove using conventional air blowing or simple cleaning methods. Therefore, there is an urgent need for a self-cleaning mechanism integrated into the torsion cylinder that can efficiently remove internal copper slag online, ensuring the quality stability of stator production and the continuity of equipment operation. Utility Model Content

[0005] The technical solution of this utility model is as follows: A self-cleaning mechanism for torsion cylinders includes a positioning seat, on which multiple torsion cylinders are stacked sequentially from the inside out. The outermost torsion cylinder is fitted with a connecting ring, which is fixedly installed on the upper surface of the outermost torsion cylinder. The connecting ring contacts and seals with the torsion cylinder to form a sealed cavity. Each of the multiple torsion cylinders has a suction hole of the same height, and the suction hole of the outermost torsion cylinder is located inside the cavity. Each torsion cylinder has a copper wire slot that communicates with the suction hole on the same torsion cylinder. The positioning seat is fixed with a vacuum suction device that communicates with the cavity.

[0006] Furthermore, the connecting ring is provided with sealing rings that contact the torsion cylinder on both the upper and lower sides of the cavity.

[0007] Furthermore, a sealing ring is provided at the top of the connecting ring, and circular steps are provided at both the top and bottom of the connecting ring. A sealing groove is formed between the steps, the sealing ring, and the torsion cylinder for placing the sealing ring. The sealing groove contacts and seals with the sealing ring.

[0008] Furthermore, a mounting plate is fixedly installed on the positioning seat, and the vacuum suction device is mounted on the mounting plate.

[0009] Furthermore, a collection bag is installed at the output end of the vacuum pump.

[0010] Furthermore, the connecting ring has several through holes on its peripheral wall, the through holes are connected to the cavity, and the through holes are fixedly connected to a straight connector, which is connected to a vacuum suction device.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a suction hole to extract copper wires at the stator end and copper slag inside the torsion cylinder, avoiding the impact of residual copper slag on stator production quality. The copper slag is collected through the cooperation of a vacuum suction device and a collection bag, achieving a convenient use effect. Attached Figure Description
