Abstract: The riveting machine for riveting two parts has a motorized-drive system (2) with an output shaft, a set (3) of mutually articulated link rods, with a first link rod (31) mounted to rotate with the output shaft and a second link rod (32) articulated to the first link rod (31), a ram (4) articulated to the second link rod (32) at one of its ends and equipped at its opposite end with an upper rivet die (5), a guide device (6) having a through-orifice in which the ram (4) is engaged, and a lower rivet die (9), able to collaborate with the upper rivet die (5) to upset the rivet, when the rivet is placed inside an orifice pierced through the parts, between the upper and lower rivet dies. The rotation of the output shaft drives the movement of the ram (4) to allow, through the link rods (31, 32) moving from a folded position to a deployed position, lowering the upper rivet die (5) to bring the rivet into the orifice.

Abstract: The invention relates to a riveting machine comprising a piercing tool (52), an upper sheet clamp (71), and a lower sheet clamp (21), mounted movable relative to each other in the direction of bringing said sheet clamps (71, 21) closer to each other, an upper riveting tool (51) and a lower riveting tool (29) for flaring a rivet disposed inside an orifice formed through the parts (8) to be riveted. The upper sheet clamp (71) has a passage opening (72) facing which the drilling tool (52) is adapted to be positioned to enable said drilling tool (52) to pierce an area of said parts (8) clamped between the upper sheet clamp (71) and the lower sheet clamp (21). The upper sheet clamp (71) and the lower sheet clamp (21) are mounted movable relative to each other along a direction transverse to the piercing axis. The invention also relates to a riveting method.
