Abstract

The invention relates to the field of optical machining, in particular to polishing equipment for a large-rise deep concave spherical lens. The polishing equipment comprises a rack, a supporting mechanism, a limiting mechanism, a scrap removing mechanism, a linear driver, a polishing mechanism, a spraying mechanism, an overturning mechanism and a cleaning mechanism, wherein the supporting mechanism is used for supporting the placed concave spherical lens; the limiting mechanism is used for preventing the concave spherical lens from shaking in the polishing process; the scrap removing mechanism is used for removing scraps on the concave spherical lens after polishing; the spraying mechanism is used for sequentially spraying a protective layer and a filling layer on the first polished mirror face of the concave spherical lens; the overturning mechanism is used for overturning the concave spherical lens by 180 degrees to make the other mirror face polished after one mirror face of the concave spherical lens is polished; and the cleaning mechanism is used for cleaning and drying the finally machined concave spherical lens. According to the polishing equipment and method for the large-rise deep concave spherical lens, the problems that manual operation is needed in the traditional large-rise deep concave spherical lens polishing process, and the working efficiency is reduced are solved, the large-rise deep concave spherical lens polishing qualification rate is increased, and the manual labor is reduced.

Description

technical field [0001] The invention relates to the field of optical processing, in particular to a polishing device and method for a large-scale high-deep concave spherical lens. Background technique [0002] With the development of optical processing technology, the spherical lens numerical control polishing technology has been widely used. In the process of spherical lens numerical control polishing, there are generally two ways to support the spherical lens. One is to use the gas top pressure elastic rubber cup floating support The other way is to use rubber rings supplemented by liquid floating support. When the support surface is flat, convex or small high concave spherical surface, the use of flat cups or corresponding liquid floating tooling can meet the requirements and make it evenly stressed, but when the support surface is large high deep concave spherical surface , due to the limitation of the elastic deformation of the rubber cup and the elastic rubber sealing...
