Abstract
An apparatus for suctioning chips cut by a drill, mist lubrication of the drill, and cooling the coil of an electromagnetic riveter includes a movable shuttle body having a drill/suction cavity open at the top to receive a drill dit, and having a tapered opening at the bottom through which the drill descends to drill a hole in a workpiece clamped by a pressure foot attached to a carrier in which the shuttle body slides. A port opening in the side of the cavity is connected to a vacuum hose through which drill chips cut by the drill bit are suctioned away from the workpiece as they are made. A second port opening in the side of the cavity aligns with a nozzle through which mist lubrication is blown on the drill bit before it starts drilling, and through which air is blown into the cavity to swirl the chips as they are being cut by the drill to facilitate their removal through the vacuum port. The coil of an electromagnetic riveter is cooled by conduction to a transducer with which the coil is in contact. The transducer is cooled by unconditioned plant air blown across a set of fins in the sides of the transducer.
