On-rail tooling system for truss assembly with variable scale and complex configuration

Abstract

The invention relates to an on-rail tooling system for truss assembly with variable scale and complex configuration, which includes a mounting plane mechanism, a folding support mechanism and a drawing bottom plate mechanism, and the two folding support mechanisms are respectively installed on two sides on the same side of the drawing bottom plate mechanism. Two installation plane mechanisms are respectively installed on the inner sides of the upper parts of the two folding support mechanisms. The installation plane mechanism includes the head frame, the movable support arm, the push-up support arm and the head fixed lock. , the middle floor, the bottom floor and the turntable bearing, the installation plane mechanism, the folding support mechanism and the drawing bottom plate mechanism can all be folded and unfolded by themselves. The invention has the advantages of large folding-expanding ratio, fewer drives, compact structure, etc., and can assist tooling equipment for high-precision on-rail assembly of various complex configuration trusses.

Description

technical field [0001] The invention belongs to the field of on-rail assembly tooling equipment, and in particular relates to an on-rail tooling system for truss assembly with variable scale and complex configuration. Background technique [0002] With the development of aerospace technology, the demand for large-scale space structures continues to increase. However, due to the limited loading capacity provided by vehicles, heavy-duty or large-scale space structures must be assembled in space. [0003] The on-orbit construction methods of large-scale space structures mainly include three types: expandable structure construction, space-forming structure construction and upright structure construction. application. There are many ways to realize the construction of upright structures. Most of the overlapping methods proposed so far are to install the truss on the base, and complete the on-orbit overlapping by multiple small robots, which effectively solves the problems caused...

Problems solved by technology

There are many ways to realize the construction of upright structures. Most of the overlapping methods proposed so far are to install the truss on the base, and complete the on-orbit overlapping by multiple small robots, which effectively solves the problems caused by manual assembly of astronauts. low safety, low efficiency, and high resource consumption. However, when it is used to overlap large and complex structures, it needs to go back and forth to fetch materials multiple times, which makes the efficiency of lapping slower and the control is complicated. It is still difficult to achieve; in addition In addition, there is another lap joint method, which is to first fix multiple truss joints on the base in sequence, then connect the truss rods between the joints to form a truss sub-unit structure, and then splice several sub-unit structures to achieve multiple The splicing of truss structures of various specifications, but there is no auxiliary tooling equipment for this method
