摘要：Friction stir fastener equipment and method in which a ries of friction stir rivets are rotatably mounted in a supply station and a computer controlled arm
terminating in a rotating working head having special gripping jaws that precily locates耗子头
and grips a lected rivet. The arm then moves the rotating rivet and progressively drives it into the work until a frictionally heated and plasticized zone of material around the shank of the rivet begins to solidify. The jaws then relea the rivet from the drive so that the rivet rotation decelerates to zero. Sufficient hardening of the zone effects the completion of one stir riveting cycle which may be automatically repeated.
