The invention relates to the technical field of friction stir welding, in particular to a stirring friction welding main shaft inclination angle adjusting structure. The stirring friction welding mainshaft inclination angle adjusting structure comprises a fixing shell, a first gear, a connecting mechanism, a first driving mechanism, a clamping and fixing mechanism, a friction welding head, a second driving mechanism and a compression cooling mechanism, wherein the first gear is rotationally connected in a spherical groove in the fixing shell in a clamped mode, moreover, the first gear is of aspherical structure, the first driving mechanism which is used for driving is arranged in the fixing shell, the connecting mechanism which is used for driving the first gear in a connecting mode is connected between a first piston and the first gear, the clamping and fixing mechanism which is used for clamping and fixing the friction welding head is connected to one end, deviating from a fixing block, of a main shaft, and the compression cooling mechanism which is used for forming cold air and cooling a workpiece while welding is carried out is arranged in the fixing shell. According to the stirring friction welding main shaft inclination angle adjusting structure, the welding angle of friction welding can be adjusted, and the welding quality can be improved.
Description
technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a structure for adjusting the inclination angle of a friction stir welding main shaft. Background technique [0002] Friction stir welding refers to the use of heat generated by the friction between the high-speed rotating welding tool and the workpiece to locally plasticize the welded material. When the welding tool moves forward along the welding interface, the plasticized material acts on the rotational friction of the welding tool The bottom flows from the front of the welding tool to the rear, and forms a dense solid-phase weld under the extrusion of the welding tool. The friction stir welding method is the same as conventional friction welding. Friction stir welding also uses friction heat and plastic deformation heat as welding heat source. The difference is that the welding process of friction stir welding is that a cylinder or other shape (such as a threa...
