APPARATUS FOR TRANSMITTING MOTION TO WORK-SUPPORTING TABLES OF MACHINE TOOLS AND THE LIKE

摘要

The frame of a machine tool supports a feed screw which can be rotated by a reversible motor and meshes with a nut connected to the work-supporting table of the machine tool by a pair of links flanking the feed screw and disposed in planes which are parallel to the axis of the feed screw. The end portions of the links are pivotable without play about pins which are embedded in the underside of the table and about pins which are embedded in the nut. Such articulate connection between the table and the nut ensures that vibrations, flexure and/or other stray movements of the feed screw are not transmitted to the workpiece or workpieces on the table.
