ABSTRACT:
A rivet system (10) locks separate parts (12, 14) of an assembly (13) together on a support fixture (20) with the clamping devices (28); which prevents release of the parts (12, 14) from the fixture (20) until a required number of rivets (51) have been counted. A rivet setting tool (50) provides insertion of the rivets (51) between the parts (12, 14), and which disposes spent rivet mandrels (62) through a vacuum tube (58) to be sensed and counted. A controller (100) automatically locks the parts in the support fixture and counts the sensed mandrels (62) to allow release of the assembly (13) only upon a predetermined count of mandrels (62).
