Description

Technical Field

[0001] The utility model belongs to the technical field of commutator processing, and in particular relates to a commutator processing device. Background Art

[0002] The commutator, commonly known as the rectifier, is a component of the DC permanent magnet series motor that allows the motor to continue to rotate. Its working principle is that when the current passes through the coil, it will rotate under the action of the permanent magnet through attraction and repulsion. When it turns to balance with the magnet, the contact piece on the commutator corresponding to the coil that was originally energized will separate from the brush, and the brush will be connected to the contact piece corresponding to the group of coils that generate the driving force. This process is repeated continuously, and the DC motor will rotate.

[0003] In the prior art, a Chinese patent with application number CN202110375067.3 discloses a commutator processing equipment, including a commutator processing equipment body composed of a sleeve, a push plate and a special-shaped strip, the inside of the push plate is fixedly connected to the outside of the sleeve, the outside of the push plate is fixedly connected to the external pusher, the sleeve includes a tube body, the outside of the tube body is fixedly connected to the inside of the push plate, a hydraulic cavity is provided inside the tube body, the inside of the hydraulic cavity is filled with hydraulic oil, and the inner wall of the hydraulic cavity is slidably connected to a piston. This commutator processing equipment solves the problem that when processing large commutators in the prior art, the traditional method is to use turning processing to form the insulating gaps, the insulating gaps need to be processed one by one, the processing efficiency is low, and there are many processes, the operation is cumbersome, the precision is difficult to control, and it is easy to cause scrapping. At the same time, a large number of burrs remain in the insulating gaps after processing, which are not easy to clean.

[0004] Traditionally, turning is used for forming, and manual drilling is mostly used. It is difficult to clamp the workpiece stably, and the accuracy is difficult to control, which can easily lead to scrapping. At the same time, a large amount of debris remains in the insulating gap after processing, which is not easy to clean. For this reason, we propose a commutator processing device.
