Primary mirror installation adjustment mechanism

Abstract

The main mirror installation and adjustment mechanism relates to a main mirror installation and adjustment mechanism, which solves the problems of complex adjustment methods, poor stability, and axial and radial mutual coupling of existing telescope main mirrors. On the three supporting bosses on the top, the main mirror chamber and the support seat are concentrically arranged, and the adjustment assembly includes the main mirror chamber insert embedded in the main mirror chamber, the receiving ball socket embedded in the bottom of the support seat, and the main mirror chamber set in the main mirror chamber. The adjusting screw in the insert, the screw ball socket embedded in the upper end of the adjusting screw, the steel ball installed between the receiving ball socket and the screw ball socket, and the lock nut installed at the bottom of the adjusting screw, the locking assembly includes The roller on the seat, the seesaw installed on the roller, the locking ball head and the locking ball socket installed on the locking screw and the butterfly gasket, the mechanism described in the present invention can adjust three degrees of freedom, And it has no effect on the shape of the primary mirror.

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 less stable adjustment methods to realize the tilt adjustment of the optical axis position of the primary mirror during the assembly process of the primary mirror, and has the following defects: [0003] 1. The adjustment method is complicated, it 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 is not well fixed, which affects the measurement accuracy. After the adjustment is completed, there may be subsequent jumps. [0005] 3. Axial and radial interference must be avoided during the adjustment process. When adjusting the tilt, it will bring about a lateral adjustment of the o...
