Automatic grinding device for bearing outer rings and grinding method

Abstract

The invention discloses an automatic grinding device for bearing outer rings, and relates to the technical field of bearing machining. The automatic grinding device comprises a first telescopic structure, a material pushing plate, a conveying table, synchronous holders, a positioning table, a supporting assistor and a driving holder. According to the automatic grinding device for the bearing outerrings, rotating arms are extruded forwards through the first telescopic structure, the frequency of the bearing outer rings falling into the conveying table is controlled, clamping pieces are controlled to clamp the bearing outer rings, then the rotating arms are extruded backwards through the first telescopic structure, the clamped bearing outer rings are sleeved with the driving holder to be fixed, bearings on the conveying table are pushed to a designated position, and the clamping pieces are made to loosen the bearing outer rings (under cooperation of first sliding grooves), so that the whole outer surfaces of the bearing outer rings can be ground through the external grinding device; and the tight fit transportation between the bearing outer rings can be guaranteed, the situation that the attached bearing outer rings are independently taken out to be ground through an additional clamping mechanism is avoided, high synchronism is achieved, and economical and efficient grinding ofthe bearing outer rings is achieved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to an automatic grinding device for the outer ring of a bearing. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings. [0003] Bearings are mainly composed of bearing inner rings, bearing outer rings, ball...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the inner peripheral surface of the inner ring of the bearing has special grinding equipment for grinding it, but the outer peripheral surface of the outer ring of the bearing does not have special equipment for grinding its outer circumference

In addition, in the prior art, before grinding the bearings, it is usually necessary to control the distance between the bearings during transmission, so that when one of the bearings is processed (the transmission needs to be stopped during processing, and the processing needs to be completed), the other bearing will not be affected ( When machining the bearing, it may be necessary to rotate the bearing when machining the bearing, and the debris from grinding will fall into another unprocessed bearing, affecting its machining quality)

Or before grinding the bearings, in order to speed up the production efficiency, keep the bearings tightly fit during transportation, but this method requires an additional mechanical arm to extract a bearing and process it separately

Therefore, the existing grinding device is difficult to achieve economical and efficient grinding
