Embodiment 1

[0020] A lens clamping ring fastening and dismounting device, comprising a lens fixing disc 1 and a positioning pin 2, the lens fixing disc 1 is provided with a positioning hole 3 matching the positioning pin 2, and the lens fixing disc 1 is provided with a fixing assembly . The lens fixing disc 1 is fixedly connected to the fixed working surface 13 through a fixing assembly. There are usually three threaded holes evenly distributed on the circumference of the lens 12. A part of the positioning pin 2 is inserted into the threaded hole, and the other part is inserted into the positioning hole 3. The positioning pin 2 Realize the limitation of the lens 12, so that the lens 12 cannot rotate, and realize the fixing of the horizontal direction of the lens 12. The disassembly and installation of the pressure ring can be realized by turning the pressure ring through the movable clamp. The fixed assembly includes a one-way bearing 4 and a base 5, the outer ring of the one-way bearing...

Abstract

The invention provides a lens pressing ring fastening and disassembling device which comprises a lens fixing disc and positioning pins. The lens fixing disc is provided with positioning holes matchedwith the positioning pins, and the lens fixing disc is provided with a fixing component. Through the ingenious design of the lens pressing ring fastening and disassembling device, the problem that a lens fixing device matched with a movable clamping plate is absent in the prior art is solved.

Description

technical field [0001] The invention relates to the field of lens dismounting tools, in particular to a lens pressure ring fastening and dismounting device. Background technique [0002] The pressure ring in the thermal imaging lens is used to fix the optical parts inside the lens, and the pressure ring and the lens body are connected by a screw structure. The Chinese patent with the application number CN201120506817.8 discloses a movable clip, which is used to fasten and disassemble the clamping ring. When the clamping ring is rotated, since its moving seat can move along the cross arm of the ruler base, it can be applied to different radii. Various lenses. The lens body needs to be fixed when the lens clamp is fastened and disassembled, and then the clamp is rotated with a movable clamp. The prior art lacks a lens fixing device that cooperates with the movable clamp. Contents of the invention [0003] The invention provides a lens clamping ring fastening and dismountin...
