Clamping and positioning mechanism for cutting bearing inner ring

Abstract

The invention discloses a clamping and positioning mechanism for cutting a bearing inner ring. The clamping and positioning mechanism comprises a housing, wherein a plurality of inner clamping blockswhich are distributed in a central symmetry mode are arranged at the top of the housing, a plurality of inner screw rods which are distributed in a central symmetry mode are arranged inside the housing, and inner sliding rods which are fixedly connected with the bottoms of the inner clamping blocks sleeve the surfaces of the inner screw rods. According to the clamping and positioning mechanism, the inner wall and the surface of the bearing inner ring can be switched for machining, the adjusting mode is relatively simple and convenient, the machining range of a clamp is expanded, the clamp doesnot need to be replaced, the machining time is saved, and the machining of the bearing inner ring is facilitated.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a clamping and positioning mechanism for cutting inner rings of bearings. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing ring is a radial bearing with one or several raceways. Annular parts of radial rolling bearings, in which the inner ring of the bearing belongs to the bearing ring. [0003] When the existing bearing inner ring is processed, forging, heat treatment and grinding are required. During the grinding process, the bearing inner ring needs to be processed by a lathe. When the existing bearing inner ring is processed by the lathe, the inner However, when the lathe is processing the workpiece, the lathe fixture can only clamp the inner or outer ring of...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a clamping and positioning mechanism for cutting the inner ring of a bearing, which solves the problem that in the prior art, when a lathe is processing a workpiece, the lathe clamp can only clamp the inner ring or outer ring of the bearing, and the processing range is narrow , the fixture needs to be replaced during processing, and the installation time is long, which affects the processing of the inner ring of the bearing
