[0020] In this embodiment, the friction welding device body 101 is a prior art, having two oppositely arranged welding parts 102, which can realize synchronous welding of both sides of the workpiece.

The two clamping blocks 110 are symmetrically arranged in the positioning frame 106, and the workpiece can be clamped and fixed on the positioning frame 106. The inner wall of the positioning frame 106 is provided with a sliding groove, and the two ends of the clamping block 110 have a protrusion that matches the sliding groove. Through the cooperation of the protrusion and the sliding groove, the clamping block 110 can slide in the positioning frame 106, and the clamping component is used to drive the two clamping blocks 110 to move in opposite directions at the same time. By arranging the positioning frame 106 between the two welding parts 102, the workpiece can be positioned and fixed, which solves the problem that although the existing technology can achieve double-sided synchronous welding, it does not have a fixing mechanism, which makes it inconvenient to place the workpiece and difficult to accurately position the workpiece.

[0022] Secondly, the guide rod 104 is fixedly connected to the support plate 103 and is located on the side of the support plate 103 close to the friction welding device body 101; the sliding sleeve 105 is slidably connected to the guide rod 104 and fixedly connected to the positioning frame 106.

Then, the workpiece is placed on the two clamping blocks 110, and the knob 112 is tightened so that the two clamping blocks 110 clamp the workpiece, thereby achieving positioning and fixing of the workpiece. By controlling the action of the drive motor 109, the horizontal position of the positioning frame 106 can be adjusted to meet different welding requirements.
