AI Technical Summary

Technical Problem

The prior art is difficult to process conical lenses when ensuring eccentricity, especially when the arc surface diameter with a large taper is too small, clamping and correction of eccentricity cannot be completed, resulting in poor appearance processing.

Method used

A conical lens processing method is adopted, including processing the mechanical shaft of the semi-finished double-convex lens, and correcting the overall edge thickness difference through precision grinding and pasting of the plate, and mechanical centering and edge grinding are carried out in each step of processing to ensure accurate eccentricity. Finally, Use a grinding wheel to process the cone surface to ensure the accuracy of the cone angle and spherical radius.

Benefits of technology

It effectively solves the problem of processing conical workpieces when ensuring eccentricity, ensures the finish of the finished product and the integrity of the tapered surface processing, and realizes the previously unfinished conical mirror processing.

Abstract

The machining method comprises the following steps that a biconvex lens semi-finished product is machined according to an existing conventional mode, and the mechanical axis of the biconvex lens semi-finished product is determined by an outer cylindrical surface; a matching disc for containing the biconvex lens semi-finished product is machined, the matching disc is subjected to accurate grinding, and the biconvex lens semi-finished product and the matching disc are pasted together from top to bottom through rosin beewax; by taking the part as a reference, processing the bottom plane of the matching disc, modifying the overall edge thickness difference of the biconvex lens semi-finished product and the matching disc, and correcting the overall thickness of the biconvex lens semi-finished product and the matching disc; the biconvex lens semi-finished product and the whole matching disc are arranged in an edge grinding connector from the bottom; and the conical surface of the top of the biconvex lens semi-finished product is machined through a grinding wheel. Conical workpieces can be machined under the condition that eccentricity is qualified, the smoothness of the A face and the B face of a finished product is effectively prevented from being affected, and conical mirrors which cannot be machined before can be machined.
