Problems solved by technology

However, it ignores the problem that the airbag polishing head produces different pressures at different positions when it is in contact with the workpiece. This problem directly brings about the edge effect problem, that is, the edge is prone to warping or collapse during processing. This phenomenon is especially

Abstract

The invention discloses an air bag polishing head mechanism capable of adjusting pressure in sections and an air bag polishing device. The polishing head mechanism comprises a backboard, a diaphragm, an air bag group and a fixed connecting structure, wherein, the backboard and the periphery of the diaphragm are connected together, a sealed cabin is formed between the backboard and the diaphragm, and the bottom of the diaphragm is a circular plane; each air bag of the air bag group is concentrically and annularly arranged in the sealed cabin, the air bag group at least comprises a main pressure air bag and a side pressure air bag, each air bag is provided with an air valve, the air valves penetrate through holes in the backboard to be connected with air pipes and then are connected with different air pumps, and an electromagnetic overflow valve capable of controlling inflation and deflation or controlling air pressure is arranged on a pipeline for connecting the air pipes with the air pumps. The air bag polishing device further comprises a transmission mechanism, an air path mechanism and a fixing mechanism. The annular air bag group mechanism can control the air pressure of the annular air bag group in real time, so that the air pressure of each position of the polishing head can be adjusted in real time, and the edge effect problem is solved.

Description

technical field [0001] The invention relates to the technical field of airbag polishing, in particular to an airbag head mechanism and an airbag polishing device capable of stepwise pressure regulation. Background technique [0002] High-quality optics are very important in modern technology. Especially high-quality aspheric optics. The machining of huge ground-based telescopes is a major technical challenge, especially for the fabrication of the optical components necessary to achieve very demanding performances. Very large ground-based telescopes require many high-quality large-diameter optical elements to construct. [0003] The use of ultra-precision optical polishing is based on computer-controlled optical surface fabrication. Compared to other polishing methods, an air-filled polishing head is used as a precise polishing tool that is flexible and adapts well to the shape of the part. As with other polishing techniques, edge quality is a key factor affecting the per...
