を特徴とするワーク台盤の昇降装置。[Scope of Claim for Utility Model Registration] A device for lifting and lowering a workpiece platform on which a workpiece is placed, in which stopper protrusions are arranged on both sides of the top surface of the base, on which an anti-tilt base is laid under the base. Vertical shaft-shaped guide sliders are erected on both sides between the top plate frame facing upward, and a work base plate having each of the guide sliders slidably penetrated is arranged horizontally,
A recess into which an internal screw nut having an annular flat plate part with a cylindrical part with parallel side surfaces is removably inserted is formed in the center of the lower surface of the workpiece base, and a screw plate serving as an elevating drive shaft is formed. The screw shaft has upper and lower ends formed into smooth circumferential shaft portions with a small diameter, and is threadedly engaged with the internal thread of the internal screw nut to be rotatably supported and erected on the base and the top plate frame. A work table characterized in that an elastic body is provided around the outer periphery of the smooth circumferential shaft portion at the lower end to press upwardly an internal screw nut that descends due to the rotation of the work table and falls out from the recessed portion of the work table. Panel lifting device.
