Problems solved by technology
A stirring head is required, which is inserted into the workpiece to be welded by rotation. Through the friction between the stirring head and the workpiece, the metal is softened and undergoes plastic flow, and a reliable connection is formed through the forging pressure exerted by the stirring head. In this process, the welder to be welded The parts are firmly fixed, but the spot welding machine in the prior art has deviations in the welding position due to the inability to stably fix the workpiece to be welded, and the fixing components need to be customized according to the shape of the workpiece to be welded, which increases the cost. The prior art has not yet solved such a problem question

The invention discloses a stirring friction spot welding machine. The stirring friction spot welding machine comprises a rotating motor, a stirring head connected to the rotating motor, a workpiece to be welded, a fixing assembly used for fixing the workpiece to be welded, an installation hole plate and an air cylinder connected to the installation hole plate, wherein the workpiece to the welded is in contact with the stirring head, and the installation hole plate is connected with the fixing assembly and can change the position of the fixing assembly. The installation hole plate is provided with a plurality of threaded holes connected with the fixing assembly. The stirring friction spot welding machine is capable of stably fixing the workpiece to be welded, so that operation stability is ensured, and the welding quality is high. By means of the stirring friction spot welding machine, the position of the fixing assembly can be changed to adapt to different specifications of workpieces to be welded, and thus cost is saved.
Description
technical field [0001] A spot welding machine, in particular a friction stir spot welding machine. Background technique [0002] Friction stir spot welding is a low-temperature solid-phase joining technology that forms firmly connected point joints under the action of frictional heat and plastic deformation energy. A stirring head is required, which is inserted into the workpiece to be welded by rotation. Through the friction between the stirring head and the workpiece, the metal is softened and undergoes plastic flow, and a reliable connection is formed through the forging pressure exerted by the stirring head. In this process, the welder to be welded The parts are firmly fixed, but the spot welding machine in the prior art has deviations in the welding position due to the inability to stably fix the workpiece to be welded, and the fixing components need to be customized according to the shape of the workpiece to be welded, which increases the cost. The prior art has not ye...
