Abstract
A rivet system (10) locks separate parts (12, 14) of an assembly (13) together on a support fixture (20) with clamping devices (28) and prevents release of the parts (12, 14) from the fixture (20) until a required number of rivets (51) have been placed. A rivet setting tool (50) provides insertion of the rivets (51) between the parts (12, 14), and disposes spent rivet mandrels (62) through a vacuum tube (58) to be sensed. A detector (72) detects the spent rivet mandrels (62) and provides a signal to a controller (100), which measures the length of the mandrel to determine proper crushing or installation of the rivet (51).
