Thrust ball bearing ring end surface groove grinding method and device

Abstract

The invention provides a thrust ball bearing sleeve ring end surface groove grinding method and a device realizing the method, and belongs to the technical field of bearing sleeve ring processing. According to the method provided by the invention, a grinding wheel trimming pen is arranged in the feeding direction of a grinding cutter, when a bearing sleeve ring is replaced, the grinding cutter returns until the grinding cutter is abutted against the pen point part of the grinding wheel trimming pen, and the grinding wheel trimming pen trims the grinding cutter. The device for realizing the method comprises a machine body, a workpiece main shaft device, a grinding wheel device, a grinding wheel feeding mechanism and a grinding wheel trimming device, wherein the workpiece main shaft device drives the bearing sleeve ring to rotate, the grinding wheel device is positioned between the bearing sleeve ring and the grinding wheel trimming device and drives a circular disc type grinding wheel to rotate at a high speed, the trimming pen of the grinding wheel trimming device performs swinging rotation along a swinging rotation track corresponding to the groove circular arc of the bearing sleeve ring through being driven by the motor, and the grinding wheel returns back onto the trimming pen for trimming during the bearing sleeve ring replacement. The method and the device provided by the invention solve the problems that the grinding wheel trimming operation of the existing thrust ball bearing sleeve ring end surface groove grinding is complicated, and the processing precision and the production efficiency can be easily influenced.

Description

technical field [0001] The invention belongs to the technical field of bearing ring processing, and in particular relates to a method and a device for grinding the end surface groove of a thrust ball bearing ring. Background technique [0002] The end surface groove of the thrust ball bearing ring is an arc-shaped groove, and the intersection line between the end surface groove and the longitudinal section passing through the center line of the ring is an arc line. After the end surface groove is formed by cutting, it needs to be ground to improve the precision of the groove. The existing grinding machines used for grinding the grooves of the end faces of thrust ball bearing rings all adopt the workpiece spindle device fixed on the top surface of the bed, the grinding wheel dresser is set at a position away from the workpiece spindle, and the grinding wheel spindle is controlled by the X-axis, Y-axis The feed mechanism with axes crossed and stacked is driven to move in the ...
