Grinding head capable of controlling pressure distribution

Abstract

The invention discloses a grinding head capable of controlling pressure distribution and belongs to the technical field of optics cold processing, and a technical problem of pressure distribution of a grinding head in the prior art is solved. The grinding head capable of controlling the pressure distribution comprises a sliding table air cylinder, a rack, a motor, air cylinders, a bearing, an upper cover plate of a bearing inner ring, an upper cover plate of a bearing outer ring, and a grinding head body, wherein the sliding table air cylinder is in threaded connection with the rack; the multiple air cylinders are uniformly distributed on the rack along the periphery of the rack, and the air cylinders are hinged to the rack; the air cylinders are connected with the upper cover plate of the bearing outer ring through spherical hinges; the motor is connected with a motor seat through a thread, and the motor seat is connected with the rack through a thread; the upper cover plate of the bearing inner ring is connected with the grinding head body through screws and tightly presses the bearing inner ring; an output shaft of the motor is fixedly connected with a ball head, the upper half portion of the upper cover plate of the bearing inner ring is a cylinder with a hole in the center, vertical through grooves are symmetrically formed in the side surfaces of the cylinder, and cylindrical pins on the two sides of the ball head are clamped into the through grooves.

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...
