ABSTRACT:
Apparatus is disclosed for supplying and installing plastic expansion rivets with breakaway mandrels in holes in a workpiece. It comprises a hand-held, trigger actuated, pneumatically-operated installation tool; a rivet-supply mechanism for supply rivets one-by-one to the tool on a timely basis; and a vacuum-operated, mandrel-removal mechanism for removing broken away mandrels from the tool. The installation tool has a hollow barrel with a nose piece at its working end for receiving and releasably holding each rivet delivered thereto. Two piston assemblies are slidably mounted in the hollow barrel: one maintains the rivet body stationary against the workpiece and the other has jaws thereon for gripping and pulling on the rivet mandrel to expand the rivet body and break away the mandrel. The hollow barrel also contains a vacuum tube through which broken-away mandrels are expelled. A control system comprising pilot pressure operated control valves supplies compressed air to the tool to effect sequential movement of the piston assemblies. Other control valves in the control system supply air to operate the rivet supply mechanism. The various control valves are operated in proper timed sequence by a pneumatic logic circuit which is responsive to actuation of a trigger-operated valve on the tool.
