The invention relates to an on-rail forming device for space structure rods, which includes an installation platform, a pipe winding and forming demoulding mechanism, a feeding mechanism, a welding mechanism and a pipe clamping and pushing mechanism, and the pipe winding and forming demoulding mechanism is arranged on the On the installation platform, a bracket is provided on one side of the pipe winding and forming demoulding mechanism, and the feeding mechanism, welding mechanism and pipe clamping and pushing mechanism can all move along the axial direction of the pipe winding and forming demoulding mechanism. On the bracket, the discharge port of the feeding mechanism corresponds to the pipe winding and forming demoulding mechanism, and the welding mechanism and the pipe clamping and pushing mechanism are respectively located at the ends of the pipe winding and forming demoulding mechanism. above. Using the on-rail forming device of the present invention, ultrasonic welding can be used to quickly wind and form regular super-long tubular structures with stable mechanical properties on rail, which can then be used to continue to build large-scale space structures such as space trusses.
Description
technical field [0001] The invention relates to the related technical field of space structure construction and molding, in particular to an on-rail forming device for space structure rods. Background technique [0002] The development mode of the existing spacecraft is ground manufacturing, and the rocket is launched and assembled after being carried to the orbit. Due to the limitation of the launch vehicle and technical level, it is very difficult to construct space large-scale facilities such as space solar cell arrays, space large-scale antennas, and space platforms. It is even technically unrealizable, so the construction of large-scale space structures in orbit is a disruptive technology that changes the size and carrying constraints of future spacecraft. In the existing research, based on thermoplastic composite material strips as raw materials, rods and space trusses are processed by means of heat source heating and pultrusion, and large-scale truss structures on the...
