Welding tool and method of elbow short pipe workpiece with installing seats

Abstract

The invention relates to an aircraft engine workpiece welding tool and method, in particular to a welding tool and method of an elbow short pipe workpiece with installing seats. The welding tool comprises an adapter, a protective barrel and the first installing seat. The adapter is arranged at the left end of the protective barrel in a sleeving mode and connected with the protective barrel. The adapter is used for being matched with a seam allowance of calipers of a welding machine, and the effect that the center of the adapter is coaxial with the center of the calipers is guaranteed. The first installing seat is detachably installed at the right end of the protective barrel. A part installing and positioning surface is arranged on the side face, facing the protective barrel, of the first installing seat. The included angle between the part installing and positioning surface and the axis of the protective barrel is identical to the included angle between the second installing seat of the elbow short pipe workpiece and an elbow short pipe of the elbow short pipe workpiece. After the second installing seat is positioned and installed on the part installing and positioning surface, the elbow short pipe is coaxial with the protective barrel. By the adoption of the welding tool and method, the effect that manual argon arc welding is replaced with automatic argon arc welding can be achieved, the welding quality is improved, and the labor intensity is relieved.

Description

[0001] 【Technical field】 [0002] The invention relates to an aero-engine workpiece welding tool and method, in particular to a welding tool and a welding method for an elbow short tube workpiece with a mounting seat. [0003] 【Background technique】 [0004] The interconnection of aero-engine conduits is generally argon-arc welding. With the development of the aviation manufacturing industry, automatic argon-arc welding is widely used in aero-engine conduit welding. However, for the welding connection between the elbow short pipe workpiece with the mounting seat and other pipes or joints, due to the structural shape limitation of the workpiece, manual argon arc welding has been used. Factors such as welding speed, relative position and distance between the welding torch and the workpiece need to be controlled manually. It is greatly affected by the experience and skill level of the operator, which may easily cause unstable product quality. [0005] 【Content of invention】 [0...
