Abstract

The invention relates to a satellite dynamic angle adjusting mechanism in a low-temperature vacuum environment. The mechanism contains a satellite coupling square frame and a crossbeam positioned below the coupling square frame. A bracket vehicle used for supporting is arranged below the crossbeam. The coupling square frame is connected to the crossbeam through rotating shafts at two ends of the square frame and a spiral elevator. Lifting motion of a lead screw of the spiral elevator drives the coupling square frame to rotate along the axis. The crossbeam is connected to the bracket vehicle through a rotating shaft positioned on a short arm and a spiral elevator positioned at one side of the rotating shaft. Elevation angle of the coupling square frame is realized when the spiral elevator pushes a long arm of the crossbeam. Angle adjustment of a satellite in two directions is realized, mutual interference during motions in the two directions is eliminated, and an adaptive design is performed in allusion to the vacuum low-temperature operating environment so as to make the mechanism meet the requirement of being used in vacuum at low temperature.

Description

technical field [0001] The invention belongs to the technical field of thermal tests in low-temperature vacuum environments. Specifically, the invention relates to a special tooling for satellite vacuum thermal tests, in particular to a satellite dynamic inclination adjustment mechanism specially used in low-temperature vacuum environments. Background technique [0002] It is specially used for satellite dynamic tilt adjustment mechanism in low temperature vacuum environment, and is a special tool for satellite vacuum thermal test. It is installed in a small and medium-sized space environment simulator, and works in a low-temperature vacuum environment during the satellite vacuum thermal test process, and is used to dynamically adjust the angle of satellite roll and pitch. The series of deep space exploration satellites, especially the spacecraft for the purpose of landing and walking, after landing, the spacecraft will experience various working conditions such as stationar...
