Abstract
An expansion tool includes a housing, a motor supported within the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel. The drive mechanism includes a cam and a drive shaft coupled to the cam. The expansion tool further includes a frame including a hub and a neck extending from the hub and having an opening. A working element is coupled to the neck and has a plurality of jaws movable from a closed position toward an expanded position in response to movement of the mandrel from a retracted position toward an extended position. The mandrel extends through the opening to engage the jaws, and the drive shaft is rotatably supported by the hub.
