Ultra-miniature bearing inner ring polishing device

Abstract

The ultra-miniature bearing inner ring polishing device comprises an operation main body, the operation main body comprises a driving seat, a slide way fixedly connected to the top of the driving seat, a lifting part slidably mounted in the slide way and an extrusion part, and the extrusion part comprises a high-pressure box which is detachably and fixedly communicated to the outer side of the lifting part; the invention relates to the technical field of bearing machining. According to the ultra-miniature bearing inner ring polishing device, the problem that in the prior art, abrasive flow machining has a strong cutting effect on a restrictive section can be effectively solved, burrs are removed, then sharp corners at intersecting lines are rounded, and meanwhile, the burrs and cuts ground by abrasive flow are contained in an abrasive flow medium and taken away along with the abrasive flow. However, for a bi-directional circulating abrasive particle flow, when the flowing abrasive is repeatedly used, more and more burrs are contained in the abrasive, and the burrs squeezed to the periphery of the abrasive are prone to scratching the surface of a workpiece, damaging the workpiece and unfavorable for long-term repeated use of the abrasive.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a polishing device for the inner ring of a superminiature bearing. Background technique [0002] Abrasive flow refers to a polishing and deburring process, also known as fluid polishing, or extrusion grinding and polishing, which is a process of polishing and deburring through a semi-fluid medium, mainly for inner holes and small and medium-sized workpieces with irregular shapes. . [0003] According to Chinese patent CN113211293A, the present invention relates to a device for precision machining of the encoder bearing inner ring by abrasive flow, which is composed of a pneumatic cylinder, a locking nut, a connecting block, an abrasive channel, a clamping structure, a worktable and an encoder. It is characterized in that: the pneumatic cylinder is installed on the connecting block, the abrasive channel is installed on the connecting block, the locking nut is installed...

AI Technical Summary

Problems solved by technology

However, for the two-way circulating abrasive flow, when the flowing abrasive is used reciprocally, more and more burrs are contained in the abrasive, and the burrs that are pushed out to the periphery of the abrasive are likely to scratch the surface of the workpiece and damage the workpiece, which is not conducive to long-term repeated use of the abrasive.
