Five-axis aspheric polishing machine tool

Abstract

The invention discloses a five-axis aspheric surface polishing machine tool, which belongs to the technical field of optical processing, and adopts a novel structure, the five-axis aspheric surface polishing machine tool comprises a base, an X-axis control unit, an XB-axis connecting table, a B-axis control unit, a main shaft control unit, a Z-axis control unit, a ZC-axis connecting table, a C-axis control unit and other structures, and each unit can independently and accurately work. Loads needing to be overcome by movement of all dimensions are remarkably reduced, and the torque and control cost of the motor are reduced. In addition, in the scheme, the B shaft is not limited by other shaft systems and can move by 0-360 degrees, so that the f number of a machinable free-form surface is as small as possible and even exceeds a hemisphere. Compared with the prior art, the optical aspherical lens polishing machine tool is light in weight, low in cost and high in precision, the machining requirements of different optical aspherical lenses can be met, and the machining efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of optical processing, and in particular relates to a five-axis aspheric surface polishing machine tool. Background technique [0002] With the development of artificial intelligence, smart cars, and the competition of great powers, the competition between great powers tends to be more high-tech competition. As an extension of the human eye, the lens is developing towards higher precision and wider viewing angle. As an indispensable and important part of an excellent optical design scheme, aspherical lenses are gradually being used by designers, but it is difficult to manufacture optical aspherical lenses, so polishing equipment that can produce optical aspherical lenses has become a key issue. In order to achieve the purpose of polishing the optical aspheric surface, the multi-axis linkage function must be realized, and the quasi-alignment processing method must be used in order to achieve the machining acc...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the structure of the aspheric polishing machine is complex, the manufacturing cost is high, and the f-number of the free-form surface is greatly limited

Although some technicians have designed a new type of optical free-form surface polishing device and method, improved the transmission structure, loaded the X and Y axes on the B axis, loaded the C axis on the Y axis, and moved the Z axis independently, the above scheme still has a structure Complexity, heavy load on the B-axis, too small swing of the B-axis, the f-number of the machinable aspheric surface should not be too small, which cannot meet the market demand of aspheric surface polishing machine tools
