ABSTRACT:
A device for aligning and supporting a nutplate against the workpiece to ch it is to be fastened during the entire fastening cycle of an automatic riveting machine. The device has a base that may be mounted on the lower ram of an automatic riveting machine. A nutplate elevator moves vertically within a sleeve extending upwardly from the base. The end of the sleeve supports the workpiece lower surface. A driver anvil has pins that may be forced against the rivet tails in response to motion of the lower ram driving pin.
In operation, the lower ram rises, clamping the workpiece between the end of the sleeve and the upper pressure foot. The nutplate elevator is lowered by applying air pressure to the top of a piston, which is contained within the anvil. A nutplate is placed on the elevator. The nutplate is raised by applying air pressure to the bottom of the piston, forcing the nutplate against the workpiece. The automatic riveting machine is programmed to drill a number of holes corresponding to the number of rivet holes in the nutplate being fastened. The riveting machine then executes a normal riveting cycle, drilling holes in the workpiece and installing rivets in the holes. The nutplate installation device may include one or more compressed air supply tubes directed towards the rivet holes for clearing debris from the holes during drilling.
