ABSTRACT:
The bolt insertion apparatus includes a driver which is partially contained within an interior volume defined by an inner cylindrical sleeve which is secured at its front end to a forward mass portion of the apparatus. An actuator coil is also positioned within the interior volume for electromagnetic actuation of the driver. An outer cylindrical sleeve includes a recoil mass at the rear end thereof, with the coil extending forwardly from the recoil mass into the interior volume of the inner sleeve. The outer sleeve is movable longitudinally relative to the inner sleeve. A spacer element is selectively removable between a forward end of the apparatus and a clamp-up nosepiece member. The apparatus is initially positioned such that there is a gap between a tool on the end of the driver and the head of the bolt. The collar-swaging apparatus includes a driver element mounted for longitudinal movement. A collar transfer arm is mounted for rotational movement into and out of the longitudinal axis of movement of the driver, for insertion of a collar onto a die which is attached to the driver. A collar-swaging die includes two portions which are slidable relative to each other for alignment of the collar onto the exposed end of the bolt. A collar-swaging apparatus includes an inner sleeve and an outer sleeve which are arranged relative to each other so that recoil of the recoil mass, with corresponding movement of the inner sleeve and a hardstop element, results in contact between the hardstop and the driver, and subsequent rearward movement of the driver results in the removal of swaging tool from the collar.
