Abstract

A rotating device for fuselage assembly of a helicopter is disclosed. The rotating device has a split structure, and comprises a main body, a lower component, a rotating bracket and a hydraulic positioning mechanism. The rotating device of the invention solves the problems that the helicopter fuselage is difficult to be positioned and fixedly connected in the rotating device due to the large sizeand the heavy weight; the relative distance between the roller and the guide rail can be effectively adjusted when the rotating bracket is installed on the main body of the tooling; the rotating device has good openness, so that the rotating device can cooperate with a robot automatic assembly system to carry out hole drill, riveting and the like, can improve assembly speed and assembly quality, and can realize automatic assembly of the fuselage.

Description

technical field [0001] The invention belongs to the technical field of automatic assembly of helicopters, and in particular relates to a rotating device for assembling a helicopter fuselage. Background technique [0002] The shape of the helicopter is complex, the number of parts is huge, the internal space is compact, and the coordination relationship is complicated. Therefore, the assembly and installation cycle of the helicopter is long and the quality requirements are stricter. [0003] At present, traditional rigid tooling is still used in helicopter assembly, with a complex structure and dense tooling frames and positioning parts. Positioning and docking are performed by manually adjusting the attitude of each part of the fuselage. The operation process is time-consuming and laborious, and the positioning accuracy is not high. This kind of rigid tooling has poor opening performance and cannot cooperate with the robot hole making system to complete drilling, riveting a...
