Abstract

The invention relates to a space capturing device, in particular to a space butt-joint capturing device for non-cooperative target satellites, and aims at solving the problems that a conventional non-cooperative target butt-joint mechanism has higher requirements for motion control accuracy, and a sensitive sensor and an accurate spray pipe gesture recognition technology are required. The device is characterized in that the lower surface of an upper casing is fixedly connected with the upper surface of a lower slide body which is inserted into a lower casing; a lower motor is fixedly mounted on the bottom surface in the lower casing; an output shaft of the lower motor is connected with the lower surface of the lower slide body through a first screw nut mechanism; an upper motor is fixedly mounted on the bottom surface in the upper casing; an output shaft of the upper motor is connected with a connecting plate through a second screw nut mechanism; a mechanical arm is mounted on the upper surface of each angle of the equilateral triangle; a torsional spring is arranged in a connecting joint of each mechanical arm. The space butt-joint capturing device is used for capturing the non-cooperative satellites.

Description

technical field [0001] The invention relates to a space capture device, in particular to a docking capture device for a space non-cooperative target satellite. Background technique [0002] The non-cooperative target docking technology is different from the previous docking technology. Its docking target is a satellite without a specific docking interface, so the apogee recoil engine (AKM) nozzle of the satellite is generally selected as the docking interface. The main disadvantage of the existing non-cooperative target docking mechanism using the apogee recoil engine as the docking interface is: before the tension pin enters the throat, the docking mechanism easily collides with the nozzle, causing the target satellite to fly away from the docking position, resulting in The whole docking fails. Therefore, it requires extremely high motion control precision, and requires sensitive sensors and accurate nozzle attitude recognition technology. Contents of the invention [0...
