Abstract

The invention discloses a stirring friction welding device for a T-shaped reinforcement structure and a welding method thereof. The welding device comprises a power mechanism and a structure shaft sleeve, wherein the structure shaft sleeve is installed on the power mechanism; a stirring needle shaft sleeve penetrates through the structure shaft sleeve; the stirring needle shaft sleeve is rotatablysupported on the structure shaft sleeve through a bearing; the stirring needle shaft sleeve is installed on an output shaft of the power mechanism; a stirring needle is installed on the stirring needle shaft sleeve; an angular welding seam static shaft shoulder is arranged outside the stirring needle in a sleeving mode; the angular welding seam static shaft shoulder is arranged on a top sleeve; asealing ring is arranged between the stirring needle shaft sleeve and the structure shaft sleeve; and two ends of the structure shaft sleeve are sealed by the power mechanism and the sealing ring toform a cooling oil cavity. According to the welding device, the complexity of a main shaft structure of a machine tool is greatly reduced, and the application range of the stirring friction welding device is widened. Due to the split design and effective cooling of the stirring needle and the static shaft shoulder structure, the modularization of the static shaft shoulder and the stirring tool isachieved, the clamping is convenient, and the service life of the welding device is greatly prolonged.

Description

technical field [0001] The invention relates to the field of friction stir welding, in particular to a T-shaped reinforced structure friction stir welding device and a welding method thereof. Background technique [0002] There are a large number of T-shaped structures in ships, airplanes, rail transit panels, etc. In order to ensure the rigidity and stability of the structure, strict requirements are put forward for the dimensional accuracy of welding T-shaped profiles and the welding of T-shaped profiles and panel panels. When the disturbance is strict, it is necessary to control Within 5mm per meter. If the arc fusion welding method is used for welding, due to the large heat input and large post-weld deformation, it is difficult to control the welding deformation. Structural security. Friction stir welding is used for solid phase welding, which can realize low stress, small deformation and high precision welding. Friction stir welding mainly produces a large amount of f...
