Abstract

An automatic drilling and riveting machine comprising a frame having a main body portion and having a front end portion disposed in a first plane, means for defining a drilling and riveting axis in the frame closely adjacent and substantially parallel to the first plane, and a ram and clamp assembly carried by the frame for holding a workpiece relative to the frame in a second plane substantially perpendicular to the first plane during drilling and riveting and for applying force for heading a rivet inserted in the workpiece. A transfer assembly carried by the frame main body portion selectively moves a drilling means and a rivet inserting and forming means each into and out of positional alignment with the drilling and riveting axis and when in such alignment toward and away from the workpiece for drilling a rivet-receiving hole in the workpiece and for inserting a rivet in the hole and forming a head on the inserted rivet in co-operation with the holding and force applying means. A rivet receiving and holding means receives rivet blanks from a supply tube and maintains them in a predetermined orientation for subsequent injection into the rivet inserting and forming means independent of the orientation of the machine.
