Abstract
An automatic riveting machine produces squeezed precision rivet connections in any working direction, including an overhead working direction, while using rivets of different lengths. A rivet bore having a precision fit and linear squeezing motions result in a precision rivet connection. The rivets are also pressed into the rivet bore by a linear motion. For this purpose, the automatic riveting machine includes a drilling unit (2) with a drill bit (212), a lubricator (204), a rivet supply unit (3) including a rivet feeder pipe (302) and rivet transfer tongs (302) journalled to a journal axis (304), and a squeezing rivet setter (4). The rivet transfer unit (3) is held in a fixed position on a support console (5) which in turn is docked to a positioning robot PR. The drilling unit (2) and the rivet setter (4) are movable along the support console (5) on guides for positioning in a working position or in a back rest position. The riveting arms (403, 404) of the rivet setter (4) perform the linear squeezing motion. The upper arm (403) has a rivet clamp (405) for receiving a rivet from the supply unit (3) and for transporting a received rivet into position in alignment with a drilled rivet hole into which the rivet is pressed with a press fit.
