Abstract

The invention discloses a high-precision automatic measurement device for a batch equipment attitude angle matrix on a satellite. According to the device, a theodolite with CCD imaging and automatic collimation functions, a visual search camera, a precise rotary table, a precise guide rail and the like are integrated; a measured satellite is fixedly arranged on the precise rotary table; the measurement device is automatically positioned by virtue of the precise guide rail and the precise rotary table according to theoretical installation positions of multiple to-be-measured equipment on the satellite; a reference cubic mirror is subjected to image recognition and search in a narrow range by virtue of the visual search camera so as to realize automatic and precise collimation; and finally, automatic measurement of the batch equipment attitude angle matrix is realized. According to the high-precision automatic measurement device for the batch equipment attitude angle matrix on the satellite disclosed by the invention, the automatic measurement of the attitude angle matrix between different pieces of equipment by taking an optical cubic mirror as the reference can be realized under the condition that theoretical installation data exists, the measurement accuracy is superior to 5'', and the measurement efficiency can reach one item per minute.

Description

technical field [0001] The invention belongs to the field of industrial measurement, and specifically relates to a measuring device for performing high-precision automatic measurement of a large number of equipment with a cubic mirror as a reference coordinate system relative to a reference standard cubic mirror attitude angle matrix in the integrated assembly of a satellite system. The device is mainly used in aerospace Advanced industrial manufacturing such as device system-level assembly integration and precision optical system integration. Background technique [0002] In the integrated manufacturing process of modern large-scale precision systems represented by satellite assembly, it is necessary to precisely measure the attitude angle matrix of a large number of equipment relative to the reference reference. The reference of equipment requiring high-precision assembly generally adopts an optical reference cube mirror, and the mirror surface normal of the reference cube...
