Vapor seal liquid-suction non-contact type hydrojet grinding wheel for numerical control polishing

Abstract

The utility model relates to a non-contact liquid-jet grinding head for gas-sealed liquid pumping for numerical control polishing, which belongs to the liquid-jet grinding head involved in the technical field of optical cold processing. The technical problem to be solved is to provide a non-contact liquid jet grinding head for gas-sealed liquid pumping for numerical control polishing. The technical solutions to be solved include hollow grinding head, polishing liquid outlet hole, collecting plate connecting frame, polishing liquid collecting plate, air inlet hole, air curtain groove, liquid pumping hole, liquid collecting tank, etc.; the polishing liquid collecting plate connects with the collecting plate connecting frame The shaft sleeve of the grinding head is fixedly connected and set on the hollow grinding head; the first air inlet hole of the polishing liquid collecting plate communicates with the first air curtain groove, and the first air curtain groove communicates with the gap between the hollow grinding head and the polishing liquid collecting plate; The second air inlet hole of the polishing liquid collecting plate communicates with the second air curtain groove, and the second air curtain groove communicates with the lower working surface of the polishing liquid collecting plate; The liquid pumping hole communicates with the space outside the polishing liquid collection plate; the polishing liquid outlet holes are distributed on the working surface of the hollow grinding head.

Description

technical field [0001] The invention belongs to the technical field of optical cold processing and relates to a gas-sealed liquid pumping non-contact liquid spray grinding head for numerical control polishing. Background technique [0002] In the field of optical technology, the optical lenses that make up various optical systems, such as lenses, plane mirrors, spherical mirrors, various aspheric mirrors, etc., need to be subjected to rough grinding, fine grinding, fine grinding, polishing and other grinding according to the technical requirements of optical design. Production, this process is called optical cold processing in the optical field. [0003] Optical cold processing machine tools have grinding heads for grinding and manufacturing optical lenses. In general, the grinding head used for CNC polishing is smaller than the grinding head for mechanical polishing, and they are all solid grinding heads. [0004] The closest existing technology to the present invention i...

AI Technical Summary

Problems solved by technology

[0005] The main problem of the liquid jet grinding head is that the polishing liquid used in the processing process cannot be collected in time, which will erode the non-polishing area of ​​the processed optical element and affect the polishing accuracy
