Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aircraft assembly, in particular to an aircraft body assembly tool. Background Art
[0002] A multi-rotor aircraft is a special unmanned helicopter with three or more rotor cantilevers. The head of each cantilever is fixed to the wing, and an independent motor is installed on the tail. The motor on each cantilever rotates to drive the rotor, thereby generating lift thrust. A multi-rotor aircraft includes a skeleton structure and a skin structure. The skin structure surrounds the skeleton structure to form the fuselage of the aircraft. During assembly, it is necessary to first install the beams and ribs separately, rivet the ribs to the beams through tooling positioning to form the skeleton of the wing, and finally glue the skin to the skeleton composed of the beams and ribs. At present, the skeleton structure has its own set of positioning tooling, and the outer skin also has corresponding assembly tooling. After the two are assembled separately, they need to be put on the shelf for the second time to realize the overall assembly. However, after the outer skin and the skeleton are put on the shelf for the second time, coordination errors may occur, and the number of tooling used in the entire assembly process is large, and the assembly cost is high.
