A high-precision bearing ring surface grinding device

Abstract

The invention discloses a plane grinding device for a high-precision bearing ring, which relates to a grinding device. The plane grinding device consists of supporting seats (7), support rods (1), bearing frames (2) and support frames (6), wherein the supporting seats (7) are arranged on both sides of a workbench (4); a plurality of fixing holes (8) are formed in the supporting seat (7); each supporting seat (7) is provided with a bearing frame (2); each bearing frame (2) is provided with a support frame (6); and the support frames (6) are connected with the bearing frames (2) through the support rods (1). The problem of plane grinding of the high-precision bearing ring within phi1000mm is solved, and plane processing of a high-precision and large-sized bearing ring as well as single end face processing of a high-precision bearing ring are realized; and the plane grinding device has the advantages of high practicability, better convenience in installing, maintaining and operating and capability of ensuring safe and reliable grinding of the bearing ring under a non-magnetizing rotary table.

Description

technical field [0001] The invention relates to a grinding device, in particular to a high-precision bearing ring plane grinding device. Background technique [0002] As we all know, the plane of the bearing ring is the most important datum plane, which is the basis for the subsequent processing. The flatness, curvature and parallel difference of the high-precision bearing ring are very demanding. The bearing ring with a size within φ400mm The flatness, curvature, and parallelism are often required to be within 1~2μm; the flatness, curvature, and parallelism of bearing rings with a size of φ1000mm are often required to be within 2~3μm. [0003] Bearing rings belong to disk parts. At present, double-end grinding machines and plane lapping machines are often used in the industry to process high-precision bearing ring planes, but bearing rings exceeding the size of φ200mm cannot be processed with high precision on double-end grinding machines; The lapping machine can only achi...
