ABSTRACT:
An improved apparatus for driving threaded fasteners into workpieces. The apparatus includes means for successively feeding workpieces to the first of two spaced apart work stations. A power drilling means drills holes into opposite ends of each workpiece at the first work station. The workpieces are then successively advanced to the second work station where a driving operation is performed. The driving operation is accomplished by successively feeding the threaded fasteners to a transfer station, transferring the fasteners from the transfer station to a loading station axially aligned with the second work station, loading the fasteners into the chuck of a power stud driver, and then driving the threaded fasteners into one of the pre-drilled holes. Transfer of the threaded fasteners between the transfer and loading stations is accomplished by pivotal movement of a placing arm and a finger attached to the placing arm. All operations are performed automatically and in timed relation to one another.
