Multi-arm forming device for space on-orbit composite braiding

A multi-arm forming device for space on-orbit composite braiding, comprising a shell, wherein a ring rail is provided on an outer ring of the shell, a plurality of magnetic levitation motion stages uniformly arranged in a circumferential array are provided on the ring rail, a combination of the plurality of magnetic levitation motion stages moves circumferentially along the ring rail, and the plurality of magnetic levitation motion stages are mounted with mechanical arm laying apparatuses, respectively;

• a retractable multi-segment connection pipe is provided at a center of the shell, and a gasbag mold is connected to an end of the retractable multi-segment connection pipe, wherein the gasbag mold achieves deformation operations of inflation and deflation through a first compressed gas source, and the first compressed gas source and a second compressed gas source are both arranged inside the shell;
• the first compressed gas source is connected to a retractable filling pipe through a first filling pipe segment, and the retractable filling pipe is arranged inside the retractable multi-segment connection pipe;
• the second compressed gas source is used for supplying gas to a spray pipe at a bottom of the shell.
