ABSTRACT:
A torch reamer includes a reamer assembly having a reamer bit and a motor which are movable toward and away from a work station. A clamping arm is pivotally mounted to a frame and is movable from an inoperative position to an operative position adjacent the work station. Movement of the clamp arm toward the work station causes a clamp member to clamp a torch nozzle and hold it in the work station while the reamer assembly rotates the reamer bit within the inside of the torch nozzle. Lifting of the torch nozzle causes the release of the clamp, the deactuation of the motor, and the retraction of the motor and reamer bit to an inoperative position.
