Tool holding apparatus |
摘要 |
An apparatus for providing a reciprocating motion. The apparatus has a housing block that contains two movable arms in spaced apart relationship to one another. The movable arms each contain a rack gear connected to a common pinion gear. One movable arm is driven by a fluid actuated cylinder. The driven movable arm then produces an equal and opposite motion in the other arm because of the interconnection of the pinion gear. Tools for altering of a workpiece may be attached to one or both ends of the movable arms. An embodiment utilizes the rotation of the pinion gear shaft to cause a translation of the entire apparatus away from a workpiece.
