Process method for eliminating bending of thin-wall bearing ring face

Abstract

The invention discloses a processing method to remove the camber of the end face of a thin-walled bearing ring, comprising a plurality of steps: use a fast adhesive to fix the thin-walled ring with planer camber and a magnetic disk into one body under natural state; do face-grinding to remove the planer camber; put the processed thin-walled bearing ring (1) horizontally at a magnetic disk (5) and make the thin-walled bearing ring keep natural state; use the fast adhesive (3) to smear uniformly around the ring; after drying, the adhesive (3) makes the bearing ring (1) and a grinding disc (2) of a grinder combine into one body; after a datum plane (4) of the bearing ring (1) is grinded by the grinding disc (2), take off the adhesive (3); then put another end face of the bearing ring (1), that is the non-datum plane on the magnetic disk (5); the datum plane (4) is surface-contacted with the magnetic disk (5), matching very well; thus, non-datum plane can be grinded according to the plane grinding method of normal ring. The method has the advantages that the method greatly improves the processing precision of thin-walled bearing ring and reduces greatly the rejection rate.

Description

Technical field: [0001] The invention belongs to the technical field of bearing processing, in particular to a processing method for eliminating the curvature of the end face of a thin-walled bearing ring. Background technique: [0002] In the bearing processing process, after the heat treatment process is completed, the first process to enter the machining process is the grinding process of the end face of the bearing ring. This process determines the processing positioning, measurement benchmark and processing accuracy of the bearing ring, and has a direct impact on the subsequent processing processes. It even affects the precision of the finished bearing. [0003] The usual end face grinding of the bearing ring is to place the bearing ring flat on the disk of the surface grinder, and then turn on the magnetic system of the disk. Under the action of the magnetic force, the bearing ring is adsorbed on the disk, and when the disk rotates Won't fall off. During the end gri...

Problems solved by technology

But it can only reduce the curvature of the bearing ring, but cannot solve the problem fundamentally

[0006] When the magnetic field force is very small, the magnetic disk has a small suction force on the thin-walled bearing ring. Under the action of the abrasive tool grinding force in the end face grinding process, it will break away from the adsorption of the magnetic disk and be thrown out of the magnetic disk, which will cause safety for the operator. Hidden danger

When the adsorption force is small, there will be abrasive particles in the gap between the ferrule and the grinding disc, which will affect the parallelism of the ferrule
