Improved Feed Mechanism for Roller Ball Base Surface Grinding and Its Using Method

Abstract

The invention relates to abrasive machining of spherical fiducial surface of a bearing roller and in particular relates to a feeding mechanism for improving abrasive machining of spherical fiducial surface of the roller and a use method of the feeding mechanism. The feeding mechanism comprises an abrasion wheel, a feeding drag plate, an air cylinder and a control device, wherein the abrasion wheel is assembled on the feeding drag plate by a shaft seat and is driven by the air cylinder for axial feeding; the air cylinder and a servo motor are arranged on a drag plate support; the feeding drag plate and the drag plate support adopt axial sliding assembly; a working end of the air cylinder is connected with a feeding push block arranged on the feeding drag plate; a trigger block is positioned between the feeding push block and the abrasion wheel; the servo motor drives the trigger block assembled on a screw nut to move in axial direction through a screw rod; and the trigger block, the feeding push block and the control device are electrically connected. The user method comprises steps of feeding the abrasion wheel, contacting the workpiece with the abrasion wheel, grinding the workpiece, resetting the abrasion wheel and the like. By utilizing the feeding mechanism, the problems that ullage of the abrasion wheel can not be detected by the prior art and peeling loss compensation of the abrasion wheel can not be carried out are solved. Size scattering difference of roller processing can be effectively reduced, and the processing efficiency and the surface quality of roller can be improved.

Description

technical field [0001] The invention relates to the grinding process of the base surface of the bearing roller, in particular to a feed mechanism for improving the grinding process of the base surface of the roller ball and a use method thereof. Background technique [0002] Bearings are the key components of national major technical equipment. With the development of roller bearing technology in China, especially the progress of mechanical equipment related to roller bearings in recent years, the demand for high-quality roller bearings is increasing day by day. At present, the manufacture of high-end bearings for cars, high-speed rail, wind power, precision machine tool spindles and other high-end bearings is blank in the domestic bearing industry and has long relied on imports. Since the development of my country's bearing industry cannot keep up, it has strongly stimulated the import of bearings. For example, in the great development of high-speed railways, all the rolle...

AI Technical Summary

Problems solved by technology

The surface finish of the workpiece after Fancheng method grinding is relatively high, but the efficiency is low, and at the same time, the loss of the grinding wheel cannot be detected, so it is not possible to compensate for the loss of grinding wheel peeling

The size of the processing is large, the feed rate is not well controlled, and it is very easy to cause processing burns or "crash", which will damage the grinding wheel
