Problems solved by technology

[0003] The assembly of the mirror support has always been the focus of the mechanical designer's design work. High-precision assembly tooling is an important guarantee for the assembly of the mirror support; among many mirror support methods, the mirror assembly supported by the back is the most mirror Supporting method, when assembling the back-supported reflector assembly, the reflective surface of the reflector is usually facing down and the back is facing up, and the support is installed on the back of the reflector. The previous assembly method did not take into account the gravity of the support itself on the reflector surface. shape, because there is no gravity in the space environment, and the gravity of the support when the mirror is assembled has an impact on the surface shape of the mirror. With the continuous improvement of the resolution of the ground pixel of the space camera, the gravity of the support The influence on the surface shape of the mirror can not be ignored more and more

Abstract

The invention discloses a single-degree-of-freedom self-adaptive balance assembly mechanism. The single-degree-of-freedom adaptive balance assembly mechanism includes: a precision platform, an adaptive balance device, a string, a bracket, and a position adjustment device; the mirror and the bracket are all arranged on the precision platform, and the The precision platform is a reference leveling; the self-adaptive balance device is connected to the support of the mirror; the position adjustment device is arranged on the support through the string, and the position adjustment device is connected to the The self-adaptive balancing device is connected, and the pulling force exerted by the position adjusting device on the string is equal to the sum of the gravitational force of the supporting member of the reflector and the self-adapting balancing device. The single-degree-of-freedom self-adaptive balance assembling mechanism provided by the invention can eliminate the influence of the support member of the reflector on the surface shape of the reflector during assembly.

Description

technical field [0001] The invention relates to the technical field of space optics, in particular to a single-degree-of-freedom self-adaptive balance assembly mechanism. Background technique [0002] Reflector is the most critical optical component in the optical system of space remote sensing camera, and its surface shape accuracy has a direct impact on imaging quality. The accuracy of its surface shape depends on two points, one is the design of the support, and the other is the assembly of the reflector. If the support design of the reflector is good, if the assembly is not good, the surface shape will drop a lot. If the design of the support is not in place, To a certain extent, if the assembly is good, the surface shape can also be improved a lot. [0003] The assembly of the mirror support has always been the focus of the mechanical designer's design work. High-precision assembly tooling is an important guarantee for the assembly of the mirror support; among many mir...
