Abstract

The invention provides welding equipment for friction stir welding of an airframe. The welding equipment comprises a welding platform. A welding arm is fixedly arranged on the left side of the top of the welding platform. A welding head is mounted on the right side of the welding arm. A component positioning device is arranged on the right side of the top of the welding platform. An airframe structure component is clamped to a component positioning clamp. The welding platform is precise to position, the structure is simple, workpieces can be disassembled and assembled conveniently and fast, and the welding equipment is convenient to use. By applying a friction stir welding technology, no rivet connection is needed during the welding of the airframe component, the weight of an airplane is reduced, and the cost of the airplane is lowered as well; and besides, mostly, the aerodynamic environment of the airplane is improved, the oil consumption is reduced, the performance of the airplane is improved, and the structural strength of the airplane is enhanced.

Description

technical field [0001] The invention belongs to the field of welding equipment, and relates to friction stir welding equipment, in particular to welding equipment for friction stir welding of aircraft fuselage. Background technique [0002] The fuselage is an important part of the aircraft. Its main function is to fix the wings, empennage, landing gear and other components to connect them into a whole; at the same time, it is also used to load personnel (crew, passengers), cargo, Fuel and various equipment. The fuselage structure of a modern aircraft is composed of longitudinal elements (along the longitudinal axis of the fuselage) - stringers, girders and transverse elements perpendicular to the longitudinal axis of the fuselage - bulkheads and skins. Frame, monocoque and semi-monocoque. At present, the main structural parts of the fuselage of general-purpose aircraft are made of aluminum alloy. Due to the "difficult weldability" and "non-weldability" of aluminum alloy, a...
