Abstract

The invention relates to a sealing tool for machining a perforated optical element, and belongs to the technical field of optical machining. The sealing tool comprises a sealing tool body, sealing rubber rings and screws with sealing rubber rings, wherein grooves and the sealing rubber rings matched with the grooves are formed in the side wall of a sealing disc in the sealing tool body, so that the sealing disc can be in sealed connection with through holes of a to-be-machined perforated optical element. The screws with the sealing rubber rings are matched with threaded through holes, so thatthe overall sealing performance of the to-be-machined perforated optical element is achieved. The to-be-machined perforated optical element with good overall sealing performance is arranged on opticalmachining equipment with a vacuum adsorption function, so that firm adsorption of the to-be-machined perforated optical element can be realized. The screws with the sealing rubber rings are disassembled after machining is finished, and the overall sealing performance of the perforated optical element is damaged, so that the separation of the sealing tool and the perforated optical element is realized.

Description

technical field [0001] The invention relates to the technical field of optical processing, in particular to a sealing tool for processing optical elements with holes. Background technique [0002] The current medium and large-caliber optical components often have a design with through holes, which brings great difficulties to the processing equipment to absorb and fix the optical components with holes. If the processing equipment is not firmly adsorbed on the optical element with holes, it will cause relative displacement between the optical element with holes and the processing equipment during the processing, which will eventually lead to an increase in the processing error of the optical element, and the tooling of general metal materials will be processed for a long time. Finally, the machining fluid will remain on the surface of the tooling, which is not only difficult to clean, but also causes corrosion to the tooling and reduces the processing accuracy of optical comp...
