Description

A carbon brush surface grinding processing equipment

technical field

The invention relates to the technical field of carbon brush processing equipment, in particular to a carbon brush surface grinding processing equipment.

Background technique

Carbon brush (Carbonbrush), also called electric brush, is widely used in many electrical equipment as a sliding contact. Carbon brushes are mainly used in graphite, fat-impregnated graphite, and metal (copper, silver) graphite. A carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery. It is generally made of pure carbon and a coagulant. A spring presses it tightly on the rotating shaft. When the motor rotates, the electric energy is transmitted to the coil through the commutator. Because its main component is carbon, it is called a carbon brush, which is easy to wear. It should be regularly maintained and replaced, and carbon deposits should be cleaned. The carbon brush looks a bit like the rubber strip of a pencil, and there are wires leading out from the top. The volume is large or small. As a sliding contact, carbon brushes are widely used in many electrical equipment. The product materials mainly include electrochemical graphite, fat-impregnated graphite, and metal (copper, silver) graphite.

In the process of carbon brush production or post-maintenance, it is necessary to polish the carbon brush to make its surface smooth. However, since the carbon brush is generally in the shape of a cube, when the surface of the carbon brush is polished, it needs to be manually turned over to make the overall grinding The efficiency is low, and the grinding mechanism cannot be automatically adjusted during the turning process, which may easily cause the carbon brush to be damaged during the grinding process, thereby affecting the grinding effect.
