Fastening and disassembling device for lens clamping ring

Abstract

The invention belongs to the field of spaceflight lens clamping ring loading and unloading, and particularly relates to a fastening and disassembling device for a lens clamping ring. The problems that an ordinary wrench cannot meet the size requirement of the fastening and disassembling of the clamping ring; the work effect is not stable enough; and the lens surface is easily scratched in the prior art are solved. The device comprises a rotary handle, a torsion bar, a clamping ring chuck, a positioning sleeve and cards. The rotary handle is fixedly connected with the middle part of the clamping ring chuck through the torsion bar. The positioning sleeve sleeves the torsion bar and is located between the rotary handle and the clamping ring chuck. The inner wall of the positioning sleeve matches the outer wall of a frame. At least two card slots are arranged in the outer periphery of the clamping ring chuck, and the cards are arranged in the card slots.

Description

technical field

[0001] The invention belongs to the field of assembly and disassembly of aerospace lens rings, in particular to a fastening and dismounting device for lens rings. Background technique

[0002] At present, the lens diameter of ultra-high-precision aerospace lenses is relatively large, and ordinary wrenches cannot meet the size requirements for fastening and dismounting of the pressure ring. At the same time, optical glass has very high requirements for preventing scratches. In the middle, it is easy to cause scratches on the surface of the lens. The Chinese patent with publication number 203311070U (publication date: 2013-11-27) solves the multi-size adaptation problem in the working condition through the movable clamping plate, but it cannot guarantee stable rotation and non-slip during the working process, and still exists Risk of scratching the lenses.
