Problems solved by technology

[0002] For the coating of large-diameter lens samples with small curvature radius, if only ordinary loading and clamping methods are used, the coating components may be installed unevenly, poor concentricity or slightly tilted during the vacuum and high-temperature coating process. Under the double influence of rotation and high-temperature thermal expansion, chipping, edge grinding and micro-cracks occur on the coating element, which affects the performance of the lens
The damage caused by this traditional clamping method is unbearable. How to improve and improve the installation method of coating samples is a problem that plagues users

Embodiment

[0021] Put the base 1 and the cylindrical base 2 through the corresponding counterbore on the base with 4 M3 cylindrical head screws 13, and then screw the screws into the corresponding 4 evenly distributed M3 screw holes to reach the base 1 and the cylinder. Shaped base 2 connection. When installing, the cylindrical base 2 should be turned over so that the side with the screw holes faces up, so as to ensure the successful connection between the base 1 and the cylindrical base 2. After installation, place the base 1 at the bottom, and the final effect will be achieved. It is the base that is in direct contact with the mounting platform.

[0022] Then screw the internal thread of the handwheel 3 onto the external thread on the cylindrical base 2, and simultaneously screw the 4 rotating handrails 4 to the handwheel 3 through the corresponding 4 M6 threaded holes on the handwheel 3 , and then operate the rotating armrest 4 to rotate the handle wheel 3 to the bottom. Then place ...

Abstract

The invention discloses a rotary disc for a large-diameter lens coating clamp. The rotary disc comprises a fixed part and a rotating part, wherein the fixed part comprises a base, an inner hexangular fillister head screw, a cylindrical base, an annular base and a polytetrafluoroethylene cushion block; the rotating part comprises a cylindrical hand wheel, more than two rotary handrails, a plurality of steel balls, a large tray, a limit ring and a tip puller screw. The rotary disc disclosed by the invention is a portable tool for installing a lens and a coating clamp and can be used for guaranteeing the stability, safety and good concentricity of the large-diameter lens coating clamp and the lens during installation so as to guarantee the success rate of coating. The rotary disc for the clamp is applicable to various mounting devices of which the concentricity, uniform contact or stable lifting need to be guaranteed.

Description

technical field [0001] The invention relates to the fields of machinery, vacuum and coating, etc., and relates to thin film preparation technology, in particular to a rotating disk of a large-diameter lens coating fixture under vacuum and high temperature coating conditions. Background technique [0002] For the coating of large-diameter lens samples with small curvature radius, if only ordinary loading and clamping methods are used, the coating components may be installed unevenly, poor concentricity or slightly tilted during the vacuum and high-temperature coating process. Under the double influence of rotation and high-temperature thermal expansion, edge chipping, edge grinding and micro-cracks will occur on the coating element, which will affect the performance of the lens. The damage caused by this traditional clamping method is unbearable. How to improve and improve the installation method of coating samples is a problem that plagues users.
