Description

A kind of frock of square oblique square piece

Technical field

The utility model relates to optics package technique field, particularly relates to a kind of frock of square oblique square piece.

Background technology

In high volume production process, how to ensure that the angle precision of prism is the key problem that each process technology scheme must solve.Because every procedure in the fabrication process all may affect angle precision, so to the control of angle precision all the time through whole manufacture process, also require that the influence factor to every procedure all should have the method for solution simultaneously.If this problem not can solve, even if there is process equipment advanced again, also can cause a large amount of reprocessed products because of the overproof of angle, workload is increased, can completely does not embody the feature of High-efficient Production.

Square oblique square piece is a kind of semi-finished product being used for making prism, and need to carry out grinding or cut the prism carrying out being processed into technological requirement, due to relatively thin, and do not have suitable frock, easy cut in the square oblique square piece process of lapping of monolithic, scrappage is high; The error of aperture, angle, size causes greatly qualification rate low.Therefore, in plane High-efficient Production, the grinding of square oblique square piece and cutting accuracy (comprising size and angle) can not lean on single-piece manually to ensure, should be realized by the guarantee of several frock clamp do.So the reasonability of Fixture designing and the accuracy of manufacture ensure whole manufacture process high efficiency production and make product keep the essential condition of high qualification rate.If the inconsistent or angle precision inaccuracy by body rise size, so just also can vary by its rise of prism that it is produced, angle also can be overproof, and defective work will be made to roll up.So the major requirement of Fixture designing is: rely on the precision of frock clamp to the requirement of the size and angle precision that ensure prism; The design rationality of frock clamp is relied on to enhance productivity.

China Patent Publication No.: 202572201U, publication date: 2012.12.05, invention and created name: the processing tool of special-shaped glass prism.This utility model discloses a kind of processing tool of special-shaped glass prism, comprise base plate, described base plate has a smooth upper surface, the surrounding of described base plate is provided with and keeps vertical side with upper surface, the bottom of described base plate is installed with terminal pad, the material of the glass plate that described base plate employing surface smoothness is good or other surfacings.This utility model operating process is simple, production efficiency is high, product gives up, and loss rate is low.But this utility model is applicable to the processing to the lower special-shaped glass prism of required precision, and singlely can only process, do not reach the requirement of the frock of the higher square oblique square piece of required precision.
