A compact space docking mechanism with internal and external clamping

Abstract

The invention relates to an internal and external clamping type compact space docking mechanism. An outer ring transmission motor works to drive an outer ring transmission gear to rotate, the outer ring transmission gear rotates to drive an outer ring rotating disc to rotate, the outer ring rotating disc rotates to enable claws to be opened or closed, and the outer wall of a target object to be clamped can be clamped when the claws are closed. An inner ring transmission motor works, the other end of an inner ring transmission screw rod is connected with one end of a nitrogen spring through a nut, the other end of the nitrogen spring is connected with an inner ring, and the rotation of the inner ring transmission screw rod can drive the inner ring to rise and fall. The initial state of thenitrogen spring is in a maximum extension state, and the nitrogen spring can compress to provide flexible clamping force to support the target object to be clamped. When the outer ring is closed and clamps the outer wall of the object to be clamped, the inner ring transmission screw rod rotates to drive the inner ring to rise. When the inner ring is in contact with the inner wall of the target object to be clamped, the nitrogen spring compresses to provide flexible clamping force to support the inner wall of the target object to be clamped, so that the requirement of synchronous clamping of the inner ring and the outer ring is met, and the internal and external clamping type compact space docking mechanism is used for docking and clamping a spacecraft nozzle.

Description

technical field [0001] The invention relates to an internal and external clamping compact space docking mechanism, that is, a compact bidirectional clamping clamping mechanism, which belongs to the technical field of space docking. Background technique [0002] The grasping of the traditional docking mechanism is directly grasped by the claws. Although it can grasp the object, it cannot guarantee the posture and precise position of the object in the claw. For non-cooperative targets, it is required to be able to grasp accurately and have enough The clamping force cannot be achieved by the existing docking mechanism. It cannot not only have the function of grasping and positioning, but also have a certain holding force and torque, and cannot guarantee the accurate position and posture of the target object, and cannot achieve accurate grasping. Contents of the invention [0003] The technical problem solved by the present invention is: to overcome the deficiencies of the pri...
