Docking ring capturing and locking mechanism and capturing and locking method

Abstract

A docking ring capturing and locking mechanism comprises at least three capturing handles; each capturing handle comprises a movable paw, a motor, a ball screw, a transmission gear, a movable paw switching piece, a linear guide rail and a shell; the motors drive the ball screws to rotate through the transmission gears; the movable paws are mounted on the ball screws through the movable paw switching pieces; the ball screws drive the movable paws to move along the linear guide rails; the ball screws and the linear guide rails are mounted on the shells; and the movable paws are used for capturing and locking external docking rings. The docking ring capturing and locking mechanism can directly cooperate with a control sub system to finish all capturing, docking and locking tasks without othermechanisms such as a mechanical arm to carry out preliminary assisted capturing and connection and is especially suitable for on-orbit and follow-up uncustomized satellites to realize on-orbit services.

Description

technical field [0001] The invention relates to a docking ring capture and lock mechanism and a capture and lock method, belonging to the technical field of space capture and docking. Background technique [0002] At present, space capture or docking in the field of domestic and foreign on-orbit services mainly adopts the following methods: 1) The universal multi-joint manipulator completes the capture and docking. The manipulator system is complex, the cost is high, and the connection It is used for space operations such as satellite maintenance; 2) The problems of the flying net docking mechanism include: the flying net cannot be separated after capture, and is mainly used for dragging off-orbit, etc.; 3) The problems of other space capture docking mechanisms include: during the docking process The impact force is large, which can damage the spaceborne scientific instruments. And it is mainly aimed at cooperation targets, and requires the target satellite to arrange insta...

AI Technical Summary

Problems solved by technology

[0002] At present, space capture or docking in the field of on-orbit service at home and abroad mainly adopts the following methods: 1) The general-purpose multi-joint manipulator completes the capture and docking. It is used for space operations such as satellite maintenance; 2) The problems of the flying net docking mechanism include: the flying net cannot be separated after capture, and is mainly used for dragging off-orbit, etc.; 3) The problems of other space capture docking mechanisms include: during the docking process Large impact, damage to spaceborne scientific instruments

And it is mainly aimed at cooperation targets, which requires the target satellite to arrange installation handles, and cannot be applied to target satellites already in orbit
