As aircraft flight speeds increase, the aerospace industry places greater demands on the precision of aircraft assembly. In the process of airplane assembly, an airplane assembly jig is indispensable. The structural design of the fixture not only has direct influence on the manufacturing workload of the fixture, the length of the period, the cost and the assembly working condition, but also has a vital effect on the manufacture of the whole airplane.

During aircraft manufacturing, especially during aircraft mass production, the number of assembly profiles used is large. The design and the function of the assembly fixture determine whether the butt joint of each cabin section of the airplane is smooth, and meanwhile, the production efficiency of the whole airplane production line is greatly influenced.

Wooden bracket quality is lighter, the transportation of being convenient for, but its course of working has higher to the manpower requirement, and wooden bracket warp easily, is difficult for making the bracket of liftable. The structural steel welding bracket is widely applied at present, not easy to deform and good in rigidity. But the structural steel bracket has heavier mass and is inconvenient to move and not suitable for occasions with frequent movement.

With the diversification of airplane structures, the assembly fixture needs to be lifted according to the airplane assembly requirements. Furthermore, due to the aircraft test flight and maintenance requirements, a better movability and adjustability of the assembly carriage is required.

The assembly jig in the prior art is complex in structure, and the wooden assembly jig does not have lifting performance. The liftable structural steel assembly bracket is mostly connected by adopting a welding mode, and has the advantages of heavy volume, poor mobility and poor adjustability.

Therefore, the applicant provides an unmanned aerial vehicle assembly combined type bracket, and aims to provide an assembly fixture with a lifting function to meet the assembly requirements of an unmanned aerial vehicle.
