Problems solved by technology

The traditional assembly and adjustment mode needs to overcome the influence of the earth's gravity because it is carried out on the ground. The installation interface of all parts of the remote sensor is basically a screw hole and a light hole, relying on the connection method of fasteners such as through screws. It takes a lot of time and labor costs to repair the flatness of the surface, and inevitably produces over-constraint and assembly stress after installation.
As the caliber of the remote sensor gradually increases, the sensitivity of the optical lens to the assembly stress also gradually increases. Excessive assembly stress will directly affect the surface shape of the mirror, thus affecting the imaging quality of the remote sensor.
Therefore, the existing traditional assembly mode has been difficult to adapt to the assembly requirements of ultra-large aperture optical remote sensors. On-orbit assembly has become an inevitable direction for the development of ultra-large-aperture remote sensors in the future, and the quick-installation interface adapted to automatic assembly in the orbit environment has become an in-orbit A key technology that rail assembly must break through

Abstract

The invention relates to an in-orbit segmented mirror assembly device, belongs to the technical field of precision mechanical engineering, and relates to a high-precision and high-reliability quick-installation interface which can be used for remote sensor in-orbit segmented mirror assembly. The quick-installation interface can be used for in-orbit remote sensor assembly, and can also be used forhigh-precision and high-reliability in-orbit assembly of other products. In such installation mode, the six degrees-of-freedom of a product can be completely constrained, and no statically indeterminate or hyper-static phenomenon can occur. The in-orbit segmented mirror assembly device can solve the interface problem of the in-orbit assembly, and has novel structure, simple and efficient assemblymethod, high precision and high stability compared with a traditional remote sensor connection mode.

Description

technical field [0001] The invention relates to an assembly device for an on-orbit segmented mirror, which belongs to the technical field of precision mechanical engineering, and relates to a high-precision, high-reliability quick-installation interface that can be applied to a remote sensor for on-orbit assembly of a segmented mirror, and can be applied to remote sensing It can also be used for high-precision and high-reliability on-orbit assembly of other products. Background technique [0002] At present, the means to improve the spatial resolution of space optical remote sensors are mainly to increase the focal length and increase the light aperture, but the increase in focal length and aperture also means that the size of the remote sensor increases, and the corresponding cost of parts manufacturing, product assembly and remote sensor launch Increase. Therefore, it is a direction of future development to divide the remote sensor into parts and launch it into orbit, and...
