Abstract

The invention discloses a device for on-rail manufacturing of a large space truss structure. The device for manufacturing a large space truss structure on rail comprises: a base plate; an outer shell, the outer shell is located above the base plate, and a mechanical Arm, the base plate is set to move along the length direction of the mechanical arm relative to the mechanical arm; 3D printing assembly, the 3D printing assembly is located in the housing and includes a feeding device and a nozzle, the feeding device It is arranged to push materials into the shower head, the shower head is arranged above the substrate, the feeding device and the shower head are arranged to be movable in a plane parallel to the substrate; the heating element, the heating The element is used to heat the material in the spray head. The device for on-orbit manufacturing of a large space truss structure according to the embodiment of the present invention can print the truss structure in space, and can break through the limitation of the device on the size of the truss structure.

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 ...
