Abstract

The invention relates to a primary mirror installing and adjusting mechanism, which comprises a support base, a primary mirror base, a connection assembly for connecting the primary mirror base with the support base and a primary mirror flexible support device arranged on the top surface of the support base and connected with a foundation, wherein a primary mirror is fixed in the primary mirror base through a pressure ring; a glue injection hole is formed in the primary mirror base; a glue guide ring is arranged between the primary mirror base and the primary mirror; the glue guide ring is communicated with the glue injection hole; the primary mirror base and the support base are concentrically arranged; the connection assembly comprises a primary mirror base insert embedded on the primary mirror base, a support base insert embedded on the support base, a spring arranged between the primary mirror base insert and the support base insert, and an adjusting screw connected with the support base and the primary mirror base; one end of the spring is fixed on the primary mirror base insert; and the other end of the spring is fixed on the support base insert. According to the invention, the technical problems of complexity and poor stability in the traditional adjustment manner can be solved. The adjusting mechanism provided by the invention has a simple and convenient adjustment manner and is capable of adjusting in six degrees of freedom without influence on the shape of the primary mirror surface shape.

Description

technical field [0001] The invention relates to a primary mirror installation and adjustment mechanism. Background technique [0002] The traditional primary mirror adjustment mechanism relies on mechanical repair methods or other poorly stable adjustment methods to achieve precise adjustment of the optical axis position of the primary mirror lens during the primary mirror assembly process, and has the following defects: [0003] 1. The adjustment method is complicated, which will affect the mirror surface, and the requirements for the adjustment personnel are relatively high; and only a few degrees of freedom can be adjusted. [0004] 2. The stability is not good, the existing primary mirror and the foundation are not well fixed, which affects the measurement accuracy; [0005] 3. Without isolation measures, the structural deformation of the installation base and the inability to isolate the heat flow will affect the primary mirror. Contents of the invention [0006] In...
