Abstract
The invention discloses a split-type friction stir welding stirring head, which relates to the technical field of friction stir welding equipment and includes a shaft shoulder, a connecting mechanism, and a clamping mechanism. A stirring probe is arranged at one end of the shaft shoulder, and the shaft shoulder is far away from One end of the stirring probe is provided with a connecting column, the side of the outer wall of the shaft shoulder close to the connecting column is provided with a heat sink hole, the end of the connecting column far away from the shaft shoulder is provided with a positioning block, and the end of the connecting column close to the shaft shoulder Blocks are arranged on the side of the outer wall. In the present invention, connecting pipes, casing pipes, intake chambers, limiting plates, vent holes, compression chambers, telescopic chambers, limiting grooves, air intake pipes, piston blocks, telescopic columns, connecting holes, connecting rods, connecting threads, arc The clamp block and the limit slider can quickly realize the installation and disassembly of the shaft shoulder and the stirring probe, and the connection mechanism will not be worn during the installation and disassembly process, which can effectively improve the stability of the stirring device.
Description
technical field [0001] The invention relates to the technical field of friction stir welding equipment, in particular to a split type friction stir welding stirring head. Background technique [0002] Friction stir welding (FSW) was invented in 1991 and is effectively used as a solid-state welding process for aluminum alloy welding. The conventional friction stir welding process is to insert a non-consumable stirring head into the butt surface of the workpiece in rotation, through the shaft The rotating friction heat of the shoulder and the stirring needle and the metal plastic deformation heat heat the material in the surrounding area to a plastic state, and the temperature is lower than the melting point during welding. At the same time, the stirring head moves along the interface to be welded at a certain welding speed, and the thermoplastic material is continuously stirred. The front of the head is shifted to the rear to form a dense weld seam. Compared with the traditio...
