Abstract

The invention relates to a capturing device, in particular to an underactuation self-adaptive capturing device capable of being folded and unfolded. The underactuation self-adaptive capturing device capable of being folded and unfolded aims to solve the problems that an existing space robot is high in weight, complex in structure and poor in reliability and is provided with a great number of driving motors. According to the underactuation self-adaptive capturing device capable of being folded and unfolded, a single-finger root joint shaft is arranged on the upper surface of one end of a substrate, a two-finger root shared joint shaft is arranged on the upper surface of the other end of the substrate, a driving assembly is arranged on the lower surface of the substrate, a first transmission shaft is arranged on the lower surface of the substrate through a first bearing block, the single-finger root joint shaft is sleeved with a first synchronous belt wheel, the first transmission shaft is sleeved with a second synchronous belt wheel, the first synchronous belt wheel is connected with the second synchronous belt wheel through a synchronous belt, the middle of the two-finger root shared joint shaft is sleeved with a first gear, and the first gear is connected with the driving assembly. The underactuation self-adaptive capturing device capable of being folded and unfolded is used for the aerospace field.

Description

technical field [0001] The invention relates to a capture device, in particular to a foldable under-actuated self-adaptive capture device, which belongs to the field of aerospace. Background technique [0002] With the development of aerospace technology, the competition in space has become increasingly fierce, and more and more spacecraft have been launched into space to perform various tasks. When the fuel carried by the spacecraft itself is exhausted or the functional units are aging and fail, the service life of the spacecraft will end. How to improve the survivability of spacecraft in space orbit and enhance its control efficiency is a difficult and hot issue for future spacecraft on-orbit service. The development of remote control and network communication technology provides the possibility to solve the above problems. Space vehicles can provide various on-orbit services with the help of remote control technology, including the capture, refueling, maintenance and re...
