High-precision silicon carbide lens rapid clamping device for polishing

Abstract

The invention belongs to the technical field of machining clamps, and particularly relates to a high-precision silicon carbide lens rapid clamping device for polishing. The clamping force of the high-precision silicon carbide lens rapid clamping device is adjustable; the clamping force is very small after being distributed to each clamping device, and damage to a precise silicon carbide lens is correspondingly reduced; deformation of the lens caused by the clamping force is small, or the integral deformation is in the same direction and is uniform, so that precision controllability at a clamping part is good; clamping devices on the same side of the placement table are driven by a linkage device, and clamping and releasing can be controlled with a very small force; resisting blocks of theclamping devices abut against corresponding first rockers during clamping, so that self-locking of the clamping devices on the same side is realized, and damage to the silicon carbide lens caused by overlarge pressure is avoided; screws are arranged on parts, which are above pressure sensors, in round barrels, so that clamping forces of different clamping devices can be adjusted; and optimum clamping forces at different positions of the silicon carbide lens are provided.

Description

technical field [0001] The invention belongs to the technical field of fixtures for machining, in particular to a fast clamping device for high-precision silicon carbide lenses for grinding. Background technique [0002] A fixture is a device that accurately supports, positions and clamps one or more workpieces to facilitate the processing, grinding, and cutting of the workpiece, or as a device for assembly, inspection, etc. The fixture can be used in a large number of During the production process, the waste of working hours can be reduced, the production efficiency can be improved, the quality of the product can be maintained, and the defect rate can be reduced. It is firmly clamped at this position to withstand the force exerted by the props during processing. The device used to fix the processing object in the production process so that it occupies the correct position to receive processing or testing is also called fixture. [0003] The authorized announcement number i...

AI Technical Summary

Problems solved by technology

Although the clamping force is adjustable, the silicon carbide to be processed is placed in the middle of the two rubber pads and clamped by the clamping piece. The clamping force is concentrated in one position. If the clamping force is too small, it is easy to be damaged during processing Spattering will cause damage to production and processing personnel, and if it is too large, it will cause certain damage to silicon carbide lenses
