Automatic assembly machine with steering/up-down control handle

摘要

An automatic screwdriver is mounted on a cantilevered support to move horizontally to various positions above a workpiece and also to move vertically to drive screws into the workpiece. A depending handle with a hand grip is used to steer the screwdriver horizontally. Up and down movement of the handle relative to the screwdriver causes a power actuator to shift the screwdriver vertically to drive a screw and to retract the screwdriver preparatory to driving of the next screw. The handle may be selectively pivoted between positions enabling either right-hand or left-hand operation of the handle.
