Aircraft section docking device

The invention relates to the field of aircraft manufacturing equipment, in particular to an aircraft section butt joint device. The aircraft section butt joint device comprises a fixed section supporting mechanism and a butt joint section supporting mechanism, and at least one of the fixed section supporting mechanism and the butt joint section supporting mechanism is provided with a movable supporting device capable of moving towards the other one in the axial direction of the section. And at least one of the fixed part section supporting mechanism and the butt joint part section supporting mechanism is provided with a rotary supporting device capable of driving the corresponding part section to rotate. When the butt joint device is used, after the sections to be connected are centered, the sections can be driven to be close to each other by moving the supporting device, and the sections are driven to be screwed tightly by rotating the supporting device, so that butt joint of the sections in threaded connect
