A mechanical arm differential friction stir welding

Abstract

The invention relates to the technical field of friction stir welding equipment, and discloses a mechanical arm differential friction stir weld. The mechanical arm differential friction stir weld includes a base; a driving motor is fixedly mounted on the bottom surface of an inner cavity of the base, an output shaft of the driving motor is fixedly connected with a driving roller in a sleeved mode,and the inner wall of the inner activity of the base is movably connected with a rotating rod located directly above the driving motor in a sleeving mode; and the exterior of the rotating rod is fixedly connected with a driven roller in a sleeved mode. According to the mechanical arm differential friction stir weld, the driving roller is driven to rotate through the driving motor, the driving roller can drive the rotating rod to rotate through the combination of a conveying belt and the driven roller, the rotating rod can drive the conveying belt to rotate through a transmission roller accordingly, the conveying belt can push the machined parts to move rightwards through a pushing plate, and finally, the purpose of continuous feeding is realized; and the welding efficiency of the mechanical arm differential friction stir weld is improved, and the practicability of the mechanical arm differential stirring friction weld is improved.

Description

technical field [0001] The invention relates to the technical field of friction stir welding equipment, in particular to a mechanical arm differential friction stir welding. Background technique [0002] Friction welding is a method of using the heat generated by the mutual movement and friction of the workpiece ends to make the ends reach a thermoplastic state, and then quickly upset to complete the welding. According to the different forms of friction welding, it can be divided into ordinary friction welding and friction stir welding. In addition to the advantages of ordinary friction welding technology, friction stir welding can also be used to connect various joint forms and different welding positions. [0003] However, the existing friction stir welding requires workers to use a wrench to turn the fixing bolts to fix the workpieces when welding the workpieces. After welding, they need to use a wrench to turn the fixing bolts to disassemble the welded workpieces. Contin...

Problems solved by technology

[0004] The invention provides a mechanical arm differential friction stir welding, which has the advantages of high welding efficiency and wide applicability, and solves the problem that the existing friction stir welding requires workers to use a wrench to turn the fixing bolt to fix the workpiece when welding the workpiece After the welding is completed, it is necessary to use a wrench to turn the fixing bolt to disassemble the welded workpiece. The material cannot be fed continuously, and it is very troublesome to replace the workpiece, resulting in low welding efficiency. At the same time, the welding head of the friction stir welding is directly fixed on the beam. , only for linear welding, not suitable for welding of special-shaped workpieces
