[0002] Riveting is a process of connecting and fixing two workpieces by squeezing rivets to deform them. Rotary riveting is one of the riveting processes and is usually achieved using a rotary riveting machine. A traditional rotary riveting machine mainly includes a frame and a lifting module and a rotating module arranged on the frame. The lifting module mainly uses an air cylinder or an oil cylinder, and the rotating module can be driven by the air cylinder or the oil cylinder to achieve up and down movement.
