A spacecraft on-orbit servicing mechanism

Abstract

The present application relates to linear motion mechanism technical field, specifically to a kind of spacecraft on-orbit maintenance mechanism, including support assembly, linear motion guide rail assembly, connecting assembly and locking assembly, support assembly includes support gasket and pedestal, first installation slot is opened in pedestal;Linear motion guide rail assembly is slidably installed in first installation slot, and can release freedom along Z axis;Connecting assembly is used to connect the maintenance piece;Locking assembly is used to detachably connect the connecting assembly on the linear motion guide rail assembly. Thus, Z axis bidirectional freedom release, other direction high bearing can be realized, and one-way freedom release of Z axis is realized by cooperating with stop block, and Z axis direction bearing is realized by cooperating with flexible joint, to provide support, bearing, thermal deformation release and other functions for the maintenance piece, facilitate the on-orbit maintenance of the maintenance piece, so as to achieve integrated breakthrough design: a set of mechanism realizes launch bearing, kinematic installation, on-orbit maintenance upgrade three functions.
