Abstract

The invention discloses a precise adjustment device for the pose of a spacecraft. The precise adjustment device comprises adjustable supports, trundles, a fixed platform, electric cylinders, a movable platform and circular adapters. The four trundles are arranged below the fixed platform, the adjustable supports are located outside the trundles below the four corners of the fixed platform, the adapters are fixedly connected to the circular movable platform, the electric cylinders are installed between the movable platform and the fixed platform with every two electric cylinders forming one group, the tops of each group of electric cylinders are fixed to the bottom of the movable platform through two connected spherical hinges, and the bottoms of each group of electric cylinders are fixed to the top of the fixed platform through two connected Hooke joints. By means of the precise adjustment device, high-precision adjustment, in six degrees of freedom, of the spacecraft is achieved, complete decoupling in six degrees of freedom can be achieved in the adjustment process, and the requirement for high-precision butt joint, under most working conditions, of the spacecraft is met.

Description

technical field [0001] The invention belongs to the technical field of tooling for attitude adjustment of spacecraft. Specifically, the invention relates to a device based on the principle of a parallel mechanism to realize precise adjustment of attitude of a spacecraft. Background technique [0002] During the final assembly of the spacecraft, there is a high-precision docking process for key components such as solar wing installation, camera installation, and antenna installation. During the installation process of the solar wing, it is necessary to ensure the accuracy requirements of the solar wing and the sail panel driving mechanism in six degrees of freedom. At present, the spacecraft is placed on the two-axis turntable, and the attitude of the six degrees of freedom of the two-axis turntable is manually adjusted. To realize the installation process of the solar wing. The whole process is complicated and time-consuming, which seriously affects the reliability and prog...
