Problems solved by technology

[0004] At present, the accuracy measurement of the two-dimensional pointing mechanism usually uses a total station / theodolite to measure the alignment of the cube mirror installed on the top of the antenna reflector at the end of the two-dimensional pointing mechanism. The alignment process of this measurement method consumes a lot of time and can only Realize the measurement of the single-point accuracy of the two-dimensional pointing mechanism, but cannot complete the continuous measurement of the accuracy of the two-dimensional pointing mechanism

Abstract

The invention provides a precision measuring device for a two-dimensional pointing mechanism, which relates to the technical field of satellite structure measurement and comprises an orientation adjusting device, a pitching adjusting device, an angle measuring device and a test table board. The orientation adjusting device comprises a supporting rotary mechanism and a pitching supporting frame, and the pitching supporting frame is installed on the supporting rotary mechanism. The pitching adjusting device comprises a mounting plate, a bearing, a first servo motor, a first speed reducer, a first rotating shaft and a second rotating shaft; the angle measuring device comprises a mounting bottom plate, a horizontal adjusting rod and an angle measuring instrument; and the pitching adjusting device is connected with the pitching supporting frame through a bearing, the bottom of the supporting swing mechanism is connected with the testing table top, and the angle measuring device is connected with the testing table top through a mounting bottom plate. According to the precision measuring device for the two-dimensional pointing mechanism, single-point measurement and continuous measurement of the precision of the two-dimensional pointing mechanism can be realized, the measurement process is simple, and the measurement time is greatly saved.

Description

technical field [0001] The invention relates to the technical field of satellite structure measurement, in particular to a two-dimensional pointing mechanism precision measurement device. Background technique [0002] In recent years, my country's aerospace technology has developed more and more rapidly. Space missions such as space exploration, space station and satellite docking have very complicated work content and operation processes, and higher and higher requirements have been put forward for the accuracy, life, and functions of space agencies. , but also put forward higher and higher requirements for the weight, energy consumption and volume of the mechanism. [0003] The two-dimensional pointing mechanism is a mechanism used for space satellites, which can realize the pointing function. The mechanism has two revolving pairs, which can complete the tracking and positioning functions of the target, so as to meet the needs of signal transmission between satellites and ...
