A grinding head with controllable pressure distribution

Abstract

The invention discloses a grinding head capable of controlling pressure distribution, which belongs to the technical field of optical cold processing and solves the technical problem of the pressure distribution of the prior art grinding head; The cover plate, the upper cover plate of the bearing outer ring and the grinding head body; the cylinder of the slide table is threadedly connected with the support; multiple cylinders are evenly distributed on the support along the circumference, and the cylinders are hinged with the support; the cylinder and the upper cover plate of the bearing outer ring pass through Ball hinge connection; the motor is connected to the motor seat through threads, and the motor seat is connected to the bracket through threads; the upper cover plate of the inner ring of the bearing is connected to the grinding head body through screws and the inner ring of the bearing is pressed tightly; the output shaft of the motor is fixedly connected to the ball head The half part of the upper cover of the inner ring of the bearing is a cylinder with a hole in the center, and the side of the cylinder is symmetrically opened with a through groove along the vertical direction, and the cylindrical pins on both sides of the ball head are snapped into the through groove.

Description

technical field [0001] The invention belongs to the technical field of optical cold processing, and in particular relates to a grinding head capable of controlling pressure distribution. Background technique [0002] The polishing process is the last link in the optical cold processing. In the polishing process, the polishing mold is usually attached to the surface of the workpiece to form a stable polishing pressure. In this way, the removal of the polishing mold can be calculated and controlled by a simple formula. However, at the edge position, since a part of the grinding head leaves the workpiece surface, the pressure on the rest of the grinding head that is in contact with the workpiece changes greatly, and the removal amount is difficult to control, eventually forming an edge effect. In the current polishing process, the edge effect has a great influence on the surface shape of the component, but it is almost inevitable. The fundamental reason is that the pressure und...
