Abstract

The invention discloses a reverse mounting type locking device for large aperture vacuum sealing elements, relates to a locking device for vacuum sealing elements, and aims at solving the problem that corresponding devices lack currently so as not to realize vacuum sealing and rapid locking mechanisms of large aperture optical elements. The device comprises a vacuum isolating component, a vacuum isolating guide component, an unloosening screw baffle and N unloosening screws, wherein the vacuum isolating guide component comprises two guide frames and two guide grooves; the guide groove is fully arranged along the inner side of the guide frame; openings of the two guide grooves in the two guide frames are opposite to each other and are respectively and fixedly connected with two opposite side ends of a lens module casing; and the vacuum isolating component gets in/out of the cavity of the lens module casing through the guide grooves. The locking device has the advantages that the problem that large optical path space is occupied by positive mounting type dismounting, the dismounting opening in the device is small, limited dismounting space in a large aperture optical focusing and frequency converting system is sufficiently utilized, the system stiffness is enhanced, and the device is time-saving and labor-saving. The device is applicable to online rapid dismounting and locking of vacuum isolating components.

Description

technical field [0001] The invention relates to a vacuum sealing element locking device. Background technique [0002] In the vacuum controllable high-throughput large-aperture optical focusing and frequency conversion system, the vacuum sealing element is used to isolate the optical element in the system from the outside world, so that the optical element in the system works in a vacuum environment of 1000Pa, and the chemical film of the optical element is improved. service life. In addition, when the optical components used for vacuum isolation need to be repaired or replaced, they need to be quickly disassembled and assembled in a limited space to minimize the impact on system running time. At present, there is a lack of corresponding devices to realize the vacuum sealing and fast locking mechanism of large-aperture optical components. Contents of the invention [0003] The purpose of the present invention is to provide a rear-mounted locking device for large-diameter...
