Abstract

The invention relates to a clamping tool applied to manufacturing of a spherical surface curved crystal and a manufacturing method. The clamping tool comprises a sleeve assembly, an external metal clamping piece and a micrometer caliper, wherein the external metal clamping piece is of a half frame structure, the sleeve assembly is clamped in a half frame of the external metal clamping piece, and the micrometer caliper is connected with the sleeve assembly; and the sleeve assembly comprises a metal sleeve, a metal base, a metal pressing block and a metal cushion block, wherein the metal sleeveis used for containing a spherical base and a crystal material, the metal sleeve is connected with a metal air suction nozzle, the metal base and the metal pressing block are arranged at the two endsof the metal sleeve and are in contact with the spherical base, and the metal cushion block is arranged between the metal pressing block and the external metal clamping piece and is connected with themicrometer caliper. Compared with the prior art, the clamping tool and the manufacturing method have the advantages of being simple, reliable, low in cost and the like, and the optical resolution ofa final optical element is ensured.

Description

technical field [0001] The invention relates to an instrument for making spherical curved crystals, in particular to a clamping tool and a manufacturing method for making spherical curved crystals. Background technique [0002] Spherical Bending Crystal Manufacturing Instrument is an important instrument and equipment for finishing crystal materials. It is an instrument that bends two spherical bases with the same radius of curvature and crystal materials and fits them closely. Spherical curved crystals need to bend the crystal material to a spherical shape during the manufacturing process, and the radius of curvature of the crystal is uniform everywhere, otherwise the resolution will be greatly reduced in the subsequent use of the curved crystal. The technology commonly used at present is to bond the required crystal and the spherical base with a transparent adhesive. Harmony and so on. In addition, when using UV-curable optical glue for bonding, the upper and lower sides...
