ABSTRACT:
Method and apparatus is provided for monitoring the installation of a blind rivet to attach together top and bottom members. The blind rivet installation tool includes a housing having an anvil seated on the rivet head. A collet is reciprocable within the tool housing and carries jaws for gripping the mandrel of the blind rivet. Retraction of the jaws by the collet displaces the jaws and the mandrel axially and causes the mandrel head to axially collapse and radially expand the hollow shank of the blind rivet into engagement with the bottom member so that the rivet attaches the top member and the bottom member. A cut off tool is actuated by an actuator to cut off the mandrel flush with the rivet head. Transducers and a process controller monitor the installation process and actuate the cut off blade upon determining that the blind rivet is properly installed.
