The invention relates to the technical field of a friction stir welding constant pressure structure device, in particular to a friction stir welding constant pressure structure device, which includes a device body, the device body includes a screw rod, and adjustment washers are fixedly installed on both sides of the screw rod A plane ball bearing is fixedly installed on the top end of the adjusting washer, and a strain gauge pressure sensor is fixedly installed on the top end of the plane ball bearing. Compared with the main shaft pressure sensor or other pressure bearing sensors, the present invention is provided with a connecting mechanism and a bearing seat, has a simpler structure, lower cost, better welding effect, and no constant pressure system has many welding build-ups and large flash. After constant pressure welding, the weld seam is straight and free of burrs. During the welding process, follow-up tracking is realized. According to the pressure value fed back by the sensor, the downward pressure of the stirring tool shoulder is automatically controlled. The surface of the workpiece is more beautiful and there is almost no welding burr. , reducing the subsequent flash grinding process steps.
Description
technical field [0001] The invention relates to the technical field of friction stir welding constant pressure structural devices, in particular to a friction stir welding constant pressure structural device. Background technique [0002] In the process of friction stir welding, the pressure exerted by the stirring needle on the workpiece has an important influence on the welding quality. In actual production, due to the unevenness of the weld surface and the deformation of the workpiece, the contact between the stirring needle and the workpiece changes continuously during welding, resulting in unstable pressure. When the welding pressure is too small, the welded joint cannot form a dense structure, resulting in a decrease in joint strength; when the welding pressure is too high, the friction between the stirring needle and the workpiece will generate too much heat, and defects such as holes and tunnels will easily form inside the joint. Therefore, it is difficult to obtain...
