Riveting machine

A riveting machine comprises a frame body, a first driving device, a second driving device, a rotating table, a mounting base, a fixing frame, a jacking mechanism, an inner hole tensioning mechanism, a pressing mechanism, a feeding mechanism, a discharging mechanism and a lifting mechanism. The rotating table is rotatably mounted on the frame body, the mounting base is mounted on the rotating table, the fixing frame is mounted on the frame body, the jacking mechanism is mounted on the fixing frame, the pressing mechanism is movably mounted on the fixing frame, the lifting mechanism is mounted on the pressing mechanism, the inner hole tensioning mechanism is mounted on the lifting mechanism, and the inner hole tensioning mechanism comprises a third driving device and an inner hole tensioning shaft. One end of the inner hole tensioning shaft is connected to the output end of the third driving device, the other end of the inner hole tensioning shaft sequentially penetrates through the lifting mechanism and the p
