Description

Technical Field

[0001] This utility model relates to the field of carbon brush polishing technology, and in particular to a carbon brush polishing device. Background Technology

[0002] A carbon brush is a mechanical sliding contactor used in electric motors. It is typically used to transmit current between the rotor and stator. Carbon brushes are made of graphite or carbon-containing materials and have high electrical conductivity and good lubrication properties. They transmit current through sliding contact in the rotating parts of the motor. During the carbon brush manufacturing process, the carbon brushes need to be polished. The main purpose of polishing the carbon brushes is to remove surface protrusions, burrs, and unevenness to ensure that the carbon brush surface is smooth and flat, thereby improving its performance and service life. When polishing carbon brushes, dust tends to accumulate on the base, affecting the cleanliness of the working environment and potentially impacting subsequent operations and product quality. Furthermore, dust can easily scatter and pollute the environment.

[0003] To address the aforementioned problems, this application proposes a carbon brush polishing device. Utility Model Content
