The invention discloses a static double-shaft-shoulder stirring friction head used for a stirring friction welding machine. The static double-shaft-shoulder stirring friction head comprises a stirring needle, an upper shaft shoulder and a lower shaft shoulder assembly, wherein the upper shaft shoulder is sleeved at the upper portion of the stirring needle, and the lower shaft shoulder assembly is sleeved at the lower end of the stirring needle. The lower shaft shoulder assembly comprises a lower shaft shoulder, an installation block with an internally-embedded bearing, a plane bearing and a locking nut, wherein the lower shaft shoulder is connected with the installation block and is sleeved at the lower end of the stirring needle, the plane bearing is sleeved at the tail end of the stirring needle and can rotate along with the stirring needle, and the locking nut is sleeved on the stirring needle and locks the plane bearing tightly. The upper shaft shoulder is fixed on a machine head of the welding machine. The upper shaft shoulder and the lower shaft shoulder are static relative to the stirring needle, thermal input of the stirring friction head on a welding seam is reduced effectively, and welding quality is further improved.
Description
technical field [0001] The invention belongs to the technical field of technical material processing and welding, and in particular relates to the improvement of a water double-shaft shoulder stirring friction head. Background technique [0002] Double-shoulder friction stir welding is a new type of friction stir welding technology. During the welding process, the workpiece is clamped by the upper and lower shoulders. The lower shoulder replaces the backing plate device of conventional friction stir welding, so it does not need welding equipment to provide a lot At the same time, this friction stir head structure makes the upsetting force of the upper and lower shoulders equal in opposite directions, and the resultant force on the entire workpiece in the direction perpendicular to the plate is zero, which is very suitable for the welding of hollow components. Therefore, this method It has broad application prospects in shipbuilding, aerospace, rail transit and other fields. ...
