Grinding disc set and grinding apparatus for finish machining of rolling surfaces of bearing rollers

Abstract

The application discloses a grinding disc set and a grinding equipment for bearing roller rolling surface finishing. The grinding equipment comprises the grinding disc set, a main machine and an external circulation system. The grinding disc set comprises a lower grinding disc, an upper grinding disc and a separation disc. The front surface of the lower grinding disc is a plane or a conical surface, and the front surface of the upper grinding disc is provided with a plane spiral groove or a conical surface spiral groove. The main machine comprises a rotating part and a loading part. The external circulation system comprises a material receiving subsystem, a material feeding subsystem, a material storage station, a plurality of material storage units and a position monitoring system, and the material storage units are used for temporarily storing the bearing rollers to be processed. During the grinding process, after the bearing rollers complete one grinding process in the grinding processing area, the bearing rollers are temporarily stored in the material storage units of the external circulation system and change the order of entering the grinding processing area, and then enter the grinding processing area again, so that the grinding process is continuously circulated until the specified technical index is reached. The application can improve the size consistency of the bearing roller rolling surface.
