Space camera reflecting mirror center support device

Abstract

A space camera reflecting mirror center support device relates to the technical field of a space camera. The space camera reflecting mirror center support device solves the problem of a poor reflecting mirror surface deformation resulted from a large adhesion area, which exists in an existing reflecting mirror support structure, of a reflecting mirror, the problem of low installation precision resulted from poor axial and radial positioning, which exist in the existing reflecting mirror support structure, when the reflecting mirror and the support structure are adhered, and other problems. The space camera reflecting mirror center support device comprises a flexible support structure, and the flexible support structure is directly obtained through a machining mode; the flexible support structure comprises a support structure and three flexible structures uniformly distributed in the circumferential direction of the support structure; and a reflecting mirror is accurately positioned and installed, and, through design of six glue grooves, adhesive stresses are small, and an influence of assembly on a surface shape of the reflecting mirror is reduced. Through design of multiple radial and axial flexile links, dynamic structural rigidity and static structural rigidity are guaranteed, influences of a borne force and a deformation of a machine body of the space camera on the reflecting mirror can be effectively eliminated, and influences of a temperature change, the gravity and other factors on the surface shape of the reflecting mirror are reduced.

Description

technical field [0001] The invention relates to the technical field of space cameras, in particular to a mirror center support technology for space cameras. Background technique [0002] The optical mirror is the core component of the space camera. Its support method and installation accuracy will directly affect the surface shape accuracy of the mirror, thereby affecting the imaging quality of the optical system. Therefore, the reasonable design of the support structure of the mirror will be very important. When working in a space environment, the complex thermal environment and mechanical environment will cause temperature changes in the structure of the camera mirror assembly and deformation of the corresponding connecting parts, which will cause the surface shape of the optical mirror to be out of tolerance, resulting in deterioration of the imaging quality of the optical system. Therefore, it is necessary to make the support structure of the space camera reflector have ...
