[0002] The self-piercing rivet process, also known as self-tapping riveting, is a method that uses the special design of rivets to quickly connect two workpieces of different materials or thicknesses. The head and tail of the rivets in this process have sharp cuts, which can automatically cut out holes of a certain size during the process of the rivet penetrating the workpiece, thereby achieving connection. The self-piercing rivet process does not require prior drilling, reducing the processing and connection steps and significantly improving production efficiency.

The two sides of the two stacked plates are placed inside the U-shaped plate 9, and the second knobs 8 on both sides are rotated. Under the connection of the second screw hole 20 and the second screw 21, the second clamping plate 19 is driven to descend, which is convenient for fixing the two plates. Then, the servo motor 15 is controlled to start, driving the reciprocating lead screw 7 to rotate, thereby driving the ball screw nut pair 16 and the connecting block 18 to move to the left, and further driving the U-shaped plate 9 and the two plates inside it to move to the left, thereby realizing the effect of feeding and improving the processing efficiency.

[0030] In some examples, the positioning mechanism includes a first screw hole 5 opened on the right side of the frame 4.
