一种光学元件加工治具及其加工使用方法
By setting a symmetrical reference system and an array-type toothed groove structure on the optical element processing fixture, stable clamping and posture switching of cylindrical optical elements for multi-plane grinding under the same fixture are achieved. This solves the problems of low efficiency and poor consistency caused by repeated clamping and calibration in the prior art, and improves processing efficiency and accuracy.

AI Technical Summary
In the existing technology, cylindrical optical elements require repeated clamping and calibration during multi-plane grinding, resulting in low processing efficiency and poor batch processing consistency. In particular, when forming a cross-sectional structure with an angle, it is difficult to ensure both processing efficiency and accuracy and consistency.
By setting a first reference surface, a second reference surface, a first parallel reference surface, and a second parallel reference surface on the fixture body, a symmetrical reference system that can be used in both directions is formed. Different grinding postures can be switched by fitting different reference surfaces with the processing platform, reducing the number of clamping and calibration times. An array-type toothed groove structure is used to stably clamp multiple cylindrical optical elements.
It enables multi-plane grinding under the same fixture clamping conditions, reduces repeated clamping and calibration processes, and improves processing efficiency and consistency. It is particularly suitable for high-throughput precision machining of small or ultra-small optical components.
