Problems solved by technology

[0002] At present, there is no dedicated lapping machine for grinding extra-large bearings. The method of lapping large bearing rings is to use a polishing machine instead of a lapping machine. The polishing machine has a simple structure, only a chuck is installed on the main shaft, and manual wooden blocks apply force. , lapping with a polishing cloth can only polish the appearance, but cannot improve the roundness, waviness, and straightness of the bearing working surface

Abstract

The invention discloses a bearing convexity ultra-precision grinding head belonging to the technical field of large bearing ring precise grinding equipment, and discloses a bearing convexity ultra-precision grinding head which can finish the precise grinding of a large bearing with a maximum diameter of 600 mm after being mounted on a machine tool. The technical scheme is as follows: a lower base plate is located above a cushion block; a mounting plate is mounted on a dovetail-shaped guide rail of the lower base plate; a transverse adjustment lead screw is fixed on the lower base plate; a transmission seat on the transverse adjustment lead screw is fixed at the lower end of the mounting plate; a transverse feed oil cylinder is mounted in the middle of the mounting plate; a piston rod of the transverse feed oil cylinder is fixed on one side of a sliding platform; a longitudinal feed oil cylinder is mounted on one side of the sliding platform through a support plate; a piston rod of the longitudinal feed oil cylinder is mounted in the sliding platform; two pairs of second cross guide rails are longitudinally mounted on the sliding platform; and an oscillation generating box is fixed on the piston rod of the longitudinal feed oil cylinder through a platform. The bearing convexity ultra-precision grinding head disclosed by the invention can realize the precise grinding of large bearing rings.

Description

technical field [0001] The invention discloses a bearing convexity super-precision head, which belongs to the technical field of fine grinding equipment for large-scale bearing rings. Background technique [0002] At present, there is no dedicated lapping machine for grinding extra-large bearings. The method of lapping large bearing rings is to use a polishing machine instead of a lapping machine. The polishing machine has a simple structure, only a chuck is installed on the main shaft, and manual wooden blocks apply force. , lapping with a polishing cloth can only polish the appearance, but cannot improve the roundness, waviness, and straightness of the working surface of the bearing. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and discloses a bearing convexity superfine head, which can finely grind large bearings with a maximum diameter of 600mm after being installed on a machine tool. [0004] In order to solve the abov...
