Device and method for grinding and polishing inner and outer walls of tubular optical parts

Abstract

The invention provides a device and method for grinding and polishing the inner and outer walls of a tubular optical part, which are used to solve the problems in the prior art that the grinding and polishing of the tubular optical part cannot be mass-produced, and the grinding and polishing precision is not high and uneven. The grinding and polishing device is composed of an inner wall grinding and polishing part and an outer wall grinding and polishing part. When grinding and polishing the inner wall, fix the part on the outer base, insert the inner wall grinding and polishing assembly into the tubular optical part, release the spring so that the convex surface of the convex grinding and polishing pad is in close contact with the inner wall of the part, put in the grinding liquid or polishing liquid, and drive the inner The connecting shaft rotates around the axis and translates along the axis, drives the outer bonding base to rotate and is opposite to the rotation direction of the inner connecting shaft, and completes the grinding and polishing of the inner wall; when the outer wall is polished, the outer wall grinding and polishing assembly surrounds the outside of the tubular optical part . The invention performs mechanical grinding and polishing on the inner and outer walls of the tubular optical parts, has large working surface contact area, high processing efficiency, and can realize mass production.

Description

technical field [0001] The invention belongs to the field of optical precision parts processing, in particular to a device and method for grinding and polishing the inner and outer walls of a tubular optical part. Background technique [0002] In precision optical equipment, tubular optical parts are a common part structure. The requirements of precision equipment for optical parts are relatively high, both in terms of the accuracy of the external dimensions and the state of the surface of the parts, and the requirements for the preparation process of optical parts and ordinary parts are more stringent. In order to reduce the friction between equipment and improve the transparency and dimensional accuracy of optical parts, it is necessary to grind and polish the inner and outer walls of tubular optical parts at the same time. When the polished surface is flat, it is generally ground and polished by a polishing machine; while the inner and outer walls of the tube are non-pla...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the tube-shaped optical parts are generally ground and polished by hand, or manually assisted by equipment, but the contact surface of the existing equipment is linear contact or the contact area is relatively small, and it is applied to large-diameter tubes. When polishing tubular optical parts, the effect is poor and the processing efficiency is low, which is not conducive to mass production
