Abstract

The invention discloses a friction welding device for an automobile hub. The friction welding device comprises a workbench and a motor, a mounting plate is installed at the upper end of the workbench,and the motor is installed on the left side of the upper end of the mounting plate; a stirring head is arranged on the left side of a scraping piece, an inner threaded hole is located in the middle of the side surface of a movable block, telescopic rods on first hydraulic cylinders penetrate through second vertical plates, a flow dividing block is arranged in the middle of the part between firstclamping plates, and the flow dividing block is fixedly connected with a third vertical plate through a fixing rod; and an air inlet is reserved in the flow dividing block, limiting grooves are reserved on the periphery inside the flow dividing block, moreover, movable rods are installed inside the limiting grooves, and second clamping plates are installed on the outer sides of the movable rods. According to the friction welding device for the automobile hub, when the outer wheel rim of the automobile hub is welded, the automobile hub can be effectively fixed, and molten metal residues on thestirring head can be conveniently cleared.

Description

technical field [0001] The invention relates to the technical field of friction stir welding equipment, in particular to a friction welding device for automobile wheel hubs. Background technique [0002] Friction welding is a way to use two different workpiece contact surfaces to rub against each other, so that the friction surfaces can be thermoplastic, and then apply relative pressure to complete fast welding; with the rise of friction welding, all walks of life began to use Friction welding to replace traditional laser welding. There are still some problems in the current friction welding device for automobile wheels. For example, before the current wheel hub is formed, the sheet-shaped rim is bent into a circle, and then the weld seam is butt-jointed by friction stir welding. However, during the butt joint, The wheel hub cannot be effectively fixed, and there will be molten metal residue on the stirring head and the stirring needle. If it is not removed, it will affect ...
