Roller superfinishing machine

Abstract

The invention relates to a roller superfinishing machine. The roller superfinishing machine comprises a roller, a roller positioning device, a rocker arm, a rocker arm motion control device, an oil stone and an oil stone feeding control device, all of which are mounted on a machine tool; the roller is a spherical roller, the roller is positioned through the roller positioning device, the rocker arm is arranged on one side of the roller spherical face, the rocker arm is controlled by the rocker arm motion control device to do reciprocated swing around the swing center, and the oil stone feeding control device is arranged on the rocker arm, and controls the oil stone to do motion close to or away from the roller spherical face. According to the roller superfinishing machine, the roller surface roughness value can be effectively reduced, through superfinishing machining, the surface roughness value of the spherical roller reaches Ra0.05 micrometer, meanwhile, the deviation from circular form of the roller can be obviously avoided through the roller superfinishing machine, and the service life of a bearing can be greatly prolonged.

Description

technical field [0001] The invention belongs to the field of special processing equipment for special process of parts, and relates to a roller superfinishing machine. Background technique [0002] When the self-aligning roller bearing is running, the contact stress of the roller is very large, and its quality has an important impact on the life and performance of the bearing. At present, the domestic demand for superfinishing of spherical rollers is increasing day by day. [0003] The traditional way to reduce the surface roughness of spherical rollers is finishing, but generally it can only reach about Ra0.2μm, and the surface geometry cannot be improved, and there may be some grinding burns. [0004] The existing roller superfinishing machine has a double-roller structure. The rollers need to be replaced when the tooling is replaced. The tooling is more complicated. Each roller needs to prepare a tooling, which is costly. The demand for spherical rollers has increased si...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a roller superfinishing machine in order to overcome the problems that the prior art cannot perform superfinishing on the roller, resulting in high surface roughness of the roller and the inability to improve the surface geometry.
