Automatic assembly machine with coordinately movable fastener driving gun and locating template

摘要

An automatic screwdriver is mounted on a coordinately movable slide structure to shift horizontally to various positions above a workpiece and also to shift vertically to drive screws into the workpiece. A stylus which moves with the slide structure coacts with an overhead template to locate the gun in precise preselected driving positions over the workpiece. Jaws hold the screw as the screwdriver is advanced downwardly and are cammed open during driving of the screw. A link stops the jaws a predetermined distance above the workpiece to permit the jaws to open in the event another screw or other obstruction is located closely adjacent the screw being driven.
