A Catching Mechanism Suitable for General Structure Surface of Spacecraft

Abstract

The invention relates to an arresting mechanism suitable for a spacecraft universal structure surface, and belongs to the technical field of on-orbit service and robots. The arresting mechanism comprises a support assembly, a drive assembly, a push disk, a sliding plate, an arresting assembly, a spring and a locking and releasing assembly. The arresting assembly comprises a connecting rod and a claw spine. Under the triggering preparatory condition, the sliding plate locked in the first position is unlocked from the first position, the sliding plate is enabled to move towards the arresting target direction by using the spring, and thus the connecting rod is driven to move, so that the connecting rod drives the claw spine stabs towards the arresting targets, whether space cooperative targetor non-cooperative targets, most surfaces of a spacecraft is covered with the universal structure surfaces, that is, aluminum honeycomb plates, the claw spine can pierce the arresting target surfaceto realize arresting. The arresting mechanism is suitable for various spacecraft, has high universality and wide range of application without the need for providing cooperative arresting feature position, and the arresting mechanism can carry out repeated and effective arresting connection and releasing separation.

Description

technical field [0001] The invention relates to a capture mechanism suitable for the surface of a general structure of a spacecraft, which belongs to the field of on-orbit service and robot technology. Background technique [0002] Failure or failure of satellites in orbit will cause a huge waste of space assets. Capture and implement on-orbit service operations such as maintenance or de-orbiting, so that the mission capacity of the failed satellite can be continued, or important orbital resources can be released. important economic and social benefits. The capture of satellites is a prerequisite for on-orbit service operations, and the design of the capture mechanism is the core component of satellite capture and one of the important factors that affect the normal on-orbit service operations of satellites. [0003] At present, the on-orbit service technology for space cooperation targets has reached a certain degree of maturity, and some on-orbit verifications have been ca...

Problems solved by technology

At present, typical foreign technical solutions include the American FREND robotic arm + replaceable end effector solution, the German DEOS and the European SMART-OLEV cone-rod capture mechanism solutions, all of which require the capture target to have specific characteristic parts that can be captured. It is difficult to apply to the capture of non-cooperative targets in space
