Abstract

The invention discloses a space large truss structure on-orbit manufacturing device which comprises a middle shaft, a base plate, a 3D printing assembly and a heating component. The middle shaft is sleeved with the base plate, the base place can move in the axial direction of the middle shaft, the 3D printing assembly comprises a supply device and a sprayer, the supply device is arranged to push materials into the sprayer, the sprayer is arranged above the base plate, the supply device and the sprayer are arranged to rotate around the middle shaft, and the heating component is used for heating the materials in the sprayer. By means of the space large truss structure on-orbit manufacturing device, a truss structure can be printed in space, and limitations on the size of the truss structure can be broken through.

Description

technical field [0001] The invention relates to the field of truss structures, in particular to an on-rail manufacturing device for a large-scale space truss structure. Background technique [0002] In related technologies, the manufacturing technology of the space truss structure is made on the ground, and then unfolded in space after being folded up and launched. The size of the large space truss structure is limited by the space of the launch vehicle. In order to reach a length of hundreds or even thousands of meters, a very high expansion ratio is required, the design is difficult, and the transportation cost is high. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a device for manufacturing large space truss structures on orbit, which can print truss structures in space, thereby reducing the weight of the structure and ...
