Riveting machine and corresponding method

A riveting machine to rivet two parts to one another, the machine comprising:

• a motorization system comprising an output shaft;
• a set of connection rods articulated on one another, comprising a first connection rod fitted to be integral in rotation with the output shaft of the motorization system, and a second connection rod articulated on the first connection rod;
• a ram articulated on the second connection rod at a first end of the ram, and provided at a second end of the ram opposite the first end with an upper rivet die, the upper rivet die being a tool for retention of a rivet and for positioning the rivet;
• a guide device configured to guide the displacement of the ram along a guide axis;
• a lower rivet die, the lower rivet die being a thrust element able to be displaced in a direction parallel to the guide axis of the guide device, in order to cooperate with the upper rivet die to upset the rivet when the rivet is positioned inside an orifice pierced through the parts to be riveted, between the upper and lower rivet dies;
• and
• a control unit configured to rotate the output shaft of the motorization system (2), to make the connection rods go from a folded position to a deployed position in which the connection rods are aligned along an axis which intersects the axis of the output shaft of the motorization system.
