A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

The present invention discloses a riveting robot, comprising: a robot part provided on a chassis, and detachably coupled with a riveting tool part through a hydraulically quick change disk; a visual position identification part provided on a side of the hydraulically quick change disk and secured on the sixth axis of the front end of the robot part; an automatic rivet feeding part provided on a mounting baseplate which is secured on a chassis through a two-stage vibration damping structure; a riveter tailing material collection part used for collecting tailing materials produced during riveting; a riveting quality judgment part used for collecting riveting data, and processing and generating a riveting curve to realize judgment of the riveting quality.

A system and method for drilling a hole in a vehicle structure and installing a fastener in the hole. A drill plate having openings and associated machine-readable elements is positioned on the structure. A drill gun is positioned in a particular opening and reads hole information from the associated element, and a computer determines whether the drill gun is properly set-up to drill the hole. A fastener insertion gun is positioned in the particular opening and reads fastener information from the element, and the computer determines whether the hole has been drilled and, if so, whether the fastener insertion gun is properly set-up to insert the fastener. A fastener delivery subsystem stores, tracks, and delivers fasteners to the fastener insertion gun. A system computer monitors the drilling of every hole, the insertion of every fastener, and the overall operation of the fastener delivery subsystem.
