specific Embodiment approach 1

[0024] Specific implementation mode 1. Combination Figure 1 to Figure 7 Describe this embodiment, the main mirror installation adjustment mechanism, including the reflector 1, the support base 4, the main mirror chamber 5, the adjustment assembly connecting the main mirror chamber and the support base, the locking assembly, and the main mirror chamber and the support base. flexible diaphragm components such as image 3 with Figure 5 As shown, the reflector 1 is bonded to three support bosses 4-1 uniformly distributed on the support base, and the support points are provided with glue guide grooves 4-2. The support boss is located at 0.68 of the diameter of the bearing seat. The bottom of the primary mirror chamber 5 is provided with a through hole 5-1 opened at the bottom of the primary mirror chamber for connecting the primary mirror chamber 5 and the adjustment assembly. A through hole 5-3 for realizing the reference transfer, and for realizing the connection with the ma...

Abstract

The invention relates to a primary mirror mounting regulating mechanism. The problems that the existing telescope primary mirror is complicated in regulating mode and bad in stability, and has the axial and radial intercoupling are solved. A reflecting mirror is adhered on three support lug bosses on a bearing seat; a primary mirror chamber and the bearing seat are concentrically arranged; an adjusting component comprises a primary mirror chamber insert inlaid on the primary mirror chamber, a stacking ball socket inlaid on the bottom of the bearing seat, an adjusting screw arranged in the primary mirror chamber insert, a screw ball socket inlaid on the upper end part of the adjusting screw, a steel ball arranged between the stacking ball socket and the screw ball socket, and a lock nut mounted on the bottom of the adjusting screw; a lock component comprises a roller inlaid on the bearing seat, a wane mounted on the roller, a lock ball, and a lock ball socket which are mounted on a lock bolt, and a butterfly-shaped gasket. The mechanism disclosed by the invention can adjust the primary mirror with three degrees of freedom without influencing the shape of the primary mirror plane.

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...
