Numerical control polishing mechanical hand of optical elements of large caliber

Abstract

The invention relates to a digital control polishing manipulator of an optical element with large caliber, which pertains to devices related to the technical filed of optical cold processing. The technical problem to be solved is to provide a digital control polishing manipulator of an optical element with large caliber; the technical proposal comprises a base system, a lifting digital control swinging plate system, a first hinge, a mechanical and manual flexible swing link system, a universal mechanism, a second hinge, a polishing head system, a swing link bracket system, an operating buttonstation and an electrical control system. The base system is the base of the manipulator; the bottom parts of the lifting digital control swinging plate system and the swing link bracket system are respectively fixed at the inclined left part and the inclined right part of the top of the base; the left part of the mechanical and manual flexible swing link system is fixedly connected with the top of the lifting digital control swinging plate system by the first hinges, while the middle part thereof is fixedly connected with the top part of the swing link bracket system by the universal mechanism and the right end thereof is fixedly connected with the polishing head system by the second hinge; the operating button station is arranged at the side surface of the base; the electrical control system is arranged in the interior of the base and is connected with the operating button station by a cable.

Description

technical field [0001] The invention belongs to the technical field of optical cold processing and relates to a device for performing numerical control polishing on large-diameter optical elements. Background technique [0002] With the rapid development of my country's national defense construction and aerospace and aviation industries, higher and more application requirements are put forward for large-aperture optical components, especially large-aperture aspheric optical components. In the optical technology field, the concept of large-aperture is generally Refers to optical elements with a diameter of more than 600mm. The diameter and relative aperture of aspheric optical elements are getting larger and larger, and the gradient of asphericity is increasing, which greatly increases the difficulty of processing. The processing method currently used is mainly the traditional tape repair and polishing method, which is divided into three stages: rough grinding, fine grinding, ...

AI Technical Summary

Problems solved by technology

Therefore, the workload in the polishing stage is very large, which makes the processing cycle very long and the efficiency is low. The elimination of local errors in the polishing process is mainly done by manual grinding by senior technicians, which is relatively dependent on people.

At present, no relevant information has been found on the large-diameter optical element numerically controlled polishing manipulator similar to the present invention
