Self-oriented large-fault-tolerance isomorphic interface for spacecraft and using method thereof

Abstract

The invention provides a self-oriented large-fault-tolerance isomorphic interface for a spacecraft and a using method thereof. A gear wheel is driven to rotate by a motor by means of a worm, a supporting sleeve is driven to rotate by the gear wheel by means of a gear wheel key, the supporting sleeve rotates to drive an inner rotating cylinder to rotate firstly, for the movement of the inner rotating cylinder, a guide plate is pushed out through a meshed guide plate driving rod, a guide plate pushing rod and a rotating pin, meanwhile, a locking positioning pin is pushed out by the supporting sleeve, after the locking positioning pin and the supporting sleeve reach a limit station, the motor stops, after the interface is aligned, the motor is started again, the supporting sleeve drives a meshed telescopic sleeve to move through the driving rod, and a connecting key is used for clamping a concave part of the locking sleeve so as to complete locking. According to the interface and the method in the invention, self-oriented fault-tolerant butt joint with large butt joint initial deviation between spacecrafts can be achieved, multi-angle butt joint under the condition of multi-face connection is achieved, the interface structure is simple, the locking force is large, the size is compact, and high-reliability and large-fault-tolerance butt joint of the spacecraft can be met; meanwhile, the control is simple, the energy consumption is low, and the task cost of actual spacecraft butt joint can be saved.

Description

technical field [0001] The invention relates to the field of spacecraft docking, in particular to a spacecraft isomorphic interface. Background technique [0002] Modular spacecraft, with its low cost, high reliability, great flexibility, and fast R&D cycle, has become the trend of future spacecraft development. The interface is responsible for the important tasks of physical connection and separation of modular spacecraft, communication, heat exchange, etc., and is the focus of modular spacecraft research. With the increasing requirements of future modular spacecraft and space assembly technology for quick change, integration, general purpose, high reliability, and large fault tolerance, the fully isomorphic docking interface with good versatility and high integration has become an important direction for the development of future interface technology.

[0003] The latest fully isomorphic integrated interface solutions, such as "Design and Qualification of a Multifunctional Interface for Modular Satellite Systems (Martin Kortmanna, 2018)", "Concepts of active payload modules and end-effectors suitable for standard interface for Robotic Manipulation of Payloads in Future SpaceMissions interface (Marko Jankovic, 2018)" and "Multi-Functional Interface for Flexibility and Reconfigurability of Future European Space Robotic Systems (Javier Vinals, 2018)", although it has realized functions such as electromechanical digital thermal integration, multi-angle docking, and complete isomorphism, However, the docking error tolerance is poor, and the current docking error tolerance does not exceed ±3mm / 5°, so a high initial docking accuracy is required, and hand-eye vision or arm-eye vision must be used, which increases the control difficulty of the space manipulator
