Super-finishing machine for spherical bearing roller

Abstract

The invention discloses a super-finishing machine for a spherical bearing roller, belonging to the field of super-finishing of a bearing part. The conventional super-finishing machine for the spherical roller is low in machining accuracy; a workpiece driving device, a tool driving device, a workpiece supporting mechanism and an electrical control system are arranged on a working table of a body of a machine tool; the workpiece driving device comprises a motor and a clamping mechanism; the clamping mechanism comprises a workpiece backup plate and a pressing mechanism; the workpiece backup plate is driven to rotate by the motor; the pressing mechanism comprises a pressing wheel and a pressing wheel driving mechanism; a workpiece clamping region is formed between the pressing wheel and the workpiece backup plate; the workpiece supporting mechanism is positioned below the workpiece clamping region; the tool driving device comprises a sliding mechanism and a swinging mechanism; the swinging mechanism comprises a swinging motor, a tool chuck, a chuck seat and a swinging rotating shaft; the tool chuck is arranged on the swinging rotating shaft and is positioned above the workpiece clamping region; a rotating shaft of the swinging motor is connected with the swinging rotating shaft through a crank-rocker mechanism; and the left-right position, the front-back position and the up-down position of the tool chuck are adjusted through the sliding mechanism. The machining accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of superfinishing of bearing parts, in particular to a spherical bearing roller superfinishing machine. Background technique [0002] A spherical roller is a roller whose outline is a circle and whose generatrix is ​​a convex arc, and the curvature centerlines of all generatrixes form a curvature center plane. Roller accuracy is a key factor affecting the quality of roller bearings, and the main accuracy indicators of rollers are the roughness and curvature shape of the rollers. In the prior art, there are mainly two ways to ensure the roughness and curvature shape requirements of spherical rollers, logarithmic curve rollers and outer spherical bearing rings. One is light finishing and the other is superfinishing. The current superfinishing machine generally includes a vibrating mechanism and a hyperbolic roller mechanism. The vibrating mechanism drives the oilstone to swing, and the double guide roller or...
