Batch chamfering jig for acousto-optic crystal block

Abstract

The invention discloses a batch chamfering clamp of acousto-optic crystal blocks. The batch chamfering clamp comprises an outer frame, a locating block, an end baffle, pressing plates and rubber pads, wherein an installation groove is formed in the upper surface of the outer frame and the locating block is fixedly installed inside the installation groove; a T-shaped protrusion structure composed of an end protrusion and a central protrusion is formed on the upper surface of the locating block, and crystal block placement areas are formed on two sides of the central protrusion on the upper surface of the locating block; the end baffle is movably arranged on the outer frame through adjusting mechanisms and can transversely move so that the crystal blocks placed in the crystal block placement areas can be clamped between the end baffle and the end protrusion; the pressing plates are detachably arranged on the central protrusion and are used for simultaneously and vertically pressing the crystal blocks placed in the crystal block placement areas on the two sides of the central protrusion; and the rubber pads are arranged on the lower surfaces of the pressing plates and can increase vertical pressing force on the crystal blocks and transverse friction force after the crystal blocks are pressed. According to the batch chamfering clamp, the processing accuracy can be guaranteed, and the processing efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a jig for product processing, in particular to a batch chamfering jig for acousto-optic crystal blocks, and belongs to the technical field of core material processing of acousto-optic tunable filters. Background technique [0002] At present, the acousto-optic crystal materials used in military electronic equipment are mainly tellurium oxide crystals, lead molybdate crystals, artificial quartz crystal materials and gallium phosphide crystals. Each acousto-optic crystal material has its own characteristics and applications. To make the core material of the acousto-optic tunable filter, it is necessary to chamfer the 12 edges of each acousto-optic crystal block to remove the chipping and chipping caused by the grinding and polishing process, reduce stress concentration, and strengthen the crystal block material strength etc. At present, the chamfering is mainly manual chamfering. The operator holds the acousto-optic crystal blo...

AI Technical Summary

Problems solved by technology

At present, the chamfering is mainly manual chamfering. The operator holds the acousto-optic crystal block and grinds it on the rotating grindstone. This manual chamfering method can only chamfer one edge of a product at a time, which is not only cumbersome in process, but also efficient. Low

In addition, the amount of grinding depends entirely on the experience of the operator. Different operators have different grinding amounts, even if the same operator has different grinding amounts at different times, resulting in poor processing uniformity.
