Abstract

The invention belongs to the technical field of machining of optical elements, and particularly relates to a large-caliber optical part elastic chucking tool and method for numerical-control grinding and polishing. By utilizing a clamp fixing apparatus, a foundation support and a spring, a large-caliber optical part is elastically installed and clamped, and the large-caliber optical part elastic chucking tool is suitable for the numerical-control grinding and polishing of an optical surface. The tool is simple and reasonable in structure and convenient to operate, and not only has a vacuum sealing function, but also can enable the optical part to have appropriate elasticity in the machining process. By adopting the apparatus and the chucking method, the close lamination of a machined surface and a polishing (accurate grinding) disc can be realized, the technical bottle neck that the numerical-control grinding and polishing cannot be adopted for the large-caliber optical surface can be solved, and the labor intensity is alleviated.

Description

technical field [0001] The invention belongs to the technical field of optical element processing, and in particular relates to a large-diameter optical part elastic clamping tool and method for numerical control grinding and polishing. Background technique [0002] On the CNC machine tool, when the optical surface is processed by the pellet fine grinding disc or the polishing disc, the processed surface must be closely attached to the polishing (finishing) disc. The traditional method is to place the part on the rubber pad, and the rubber pad is expanded by air pressure to lift the part to achieve a close fit between the processed surface and the polishing (finishing) disc. But this method requires the size of the polishing (finishing) disc to be larger than 1.5 times the diameter of the part. For large-diameter parts, the polishing (finishing) disc of 1.5 times the diameter often exceeds the working range of the CNC machine tool and cannot be clamped. Therefore, the preci...
