On-orbit Additive Manufacturing Device for Rods

Abstract

The invention discloses a rod piece on-orbit additive manufacturing device comprises an installation frame, two clamping devices arranged on the installation frame, and two sets of first driving devices, second driving devices and third driving devices; the two clamping devices are arranged in the vertical direction; the clamping devices comprise clamping plate assemblies used for vertically clamping a rod piece; the two first driving devices are separately used for driving the two clamping devices to move in the first horizontal direction; the two second driving devices are separately used for driving the two clamping devices to move in the second horizontal direction; the two third driving devices are separately used for driving the two clamping devices to move in the third horizontal direction; the first horizontal direction is perpendicular to the second horizontal direction; the top portion of the installation frame is provided with a spraying device and a spraying driving device;and the spraying driving device is used for driving the spraying device to move in the horizontal plane. The rod piece on-orbit additive manufacturing device can produce a truss rod in the space orbit, especially the manufacture of a super long rod, and provides the condition for the truss structure in the space orbit.

Description

technical field [0001] The invention relates to the technical field of truss manufacturing, in particular to an on-rail additive manufacturing device for rods. Background technique [0002] There are a large number of truss structures in orbital vehicles, which are mainly used for antennas, solar panels, etc. [0003] At present, the launch method of the truss is to design and manufacture a large foldable truss on the ground first, and then send it into orbit by a launch vehicle after folding, unfold it on the orbit, and deform it into a predetermined shape. [0004] This method is limited by the size of the launch vehicle, and it is difficult to realize the launch of a super-large truss. In addition, the force of the truss in space is very small, and the structural strength can be designed with a small amount. However, in order to withstand the large overload condition during the rocket launch, the folded truss must have great strength, resulting in an increase in the weig...

Problems solved by technology

[0004] This method is limited by the size of the launch vehicle, and it is difficult to realize the launch of a super-large truss

In addition, the force of the truss in space is very small, and the structural strength can be designed with a small amount. However, in order to withstand the large overload condition during the rocket launch, the folded truss must have great strength, resulting in an increase in structural weight and increased launch. cost

Since the truss requires a large expansion ratio, the structure is often more complicated, and failures often occur during expansion, resulting in greater losses

[0005] In addition, the manufacture of trusses on the ground is limited by the working space of the manufacturing equipment, and the size of the workpiece cannot be larger than the size of the equipment, which is not suitable for the manufacture of super long rods in the truss
