AI Technical Summary

Technical Problem

When grinding the outer groove end face of existing high-speed spindle bearings, metal debris is easily left inside the bearing, which leads to increased roller friction and affects the bearing's stability and lifespan.

Method used

A high-speed spindle bearing outer groove end face ultra-precision machine was designed, which adopts a grinding component and an adsorption shell structure. The grinding head scrapes off the debris and the adsorption shell is used to adsorb it into the shell. At the same time, a self-rotating clamping component is used to reduce friction and wear.

Benefits of technology

It effectively removes metal chips generated during the grinding process, avoids roller wear, improves bearing stability and service life, ensures the stability of the machining process, and has the ability to clamp different types of bearings.

Abstract

The invention belongs to the technical field of superfinishing machines, and particularly relates to an outer groove end face superfinishing machine of a high-speed main shaft bearing. The overturning protection cover is arranged at the top of the supporting part, and an operation screen is arranged on the front face of the overturning protection cover; the machining bearing is arranged in the supporting component; the clamping parts are symmetrically arranged on the upper side and the lower side of the supporting part. According to the device, surrounding type grinding work can be conducted on the end face of an outer groove of a bearing through matched grinding tool bits on the two sides, the rough surface and impurity particles in the outer groove of the bearing are ground, the end face of the outer groove of the bearing is smoother, but metal chippings generated by grinding are likely to remain in the bearing, and a roller in the bearing is abraded; due to the fact that the long connecting plate is attached to the outer groove of the bearing, after grinding is completed, grinding work is carried out smoothly under the condition that the long connecting plate is not moved, chippings in the outer groove of the bearing are accurately sucked out through the adsorption shell which is attached to the machined bearing and rotates in a surrounding mode, and therefore the chippings mixed in the roller are eliminated, and the problem that the roller is abraded is solved.
