technical field [0001] The invention relates to the field of mechanical assembly, and in particular proposes an auxiliary device for realizing six-degree-of-freedom precision adhesive assembly of a star sensor detector, which is also suitable for mechanical assembly of parts that adopt adhesive assembly and have three-axis pointing accuracy requirements. Background technique [0002] The star sensor takes the star in the celestial inertial coordinate system as a reference. The star is imaged on the detector through the optical lens to obtain the image point coordinates, and the star sensor is calculated in the celestial inertial coordinate system according to the image point coordinates. The opto-mechanical assembly is the execution part of star sensor imaging, mainly composed of detector and optical lens. In addition to the aberration of the optical lens, the factors that cause the measurement error of the image point coordinates of the star sensor are mainly caused by the ...

Problems solved by technology

However, in this method, the control of the assembly process is not strict, and the process parameters are not quantitatively controlled, resulting in poor consistency of product assembly accuracy, uncontrollable assembly and adjustment cycle, etc., and poor assembly process, which is not conducive to the improvement of product quality and production efficiency.

[0004] In addition, since the three-axis pointing accuracy requirements of the measurement coordinate system on the detector and the installed reference coordinate system on the prism are transmitted through the base, if the assembly accuracy of the detector is low, the installation offset error of the star sensor will be uncontrollable
