Abstract
A workpiece holding means for machine tools and more particularly for milling and/or drilling machines, comprising a pivoting bridge supported between two bearing walls. The bearing walls respectively laterally delimit a working area. At least one drive motor serves for pivoting the pivoting bridge, such motor being arranged outside the working area on at least one outer side of the bearing walls. The pivoting bridge is provided with a gear ring adjacent to one or both of the inner sides of the bearing walls, such gear ring being drivingly connected with the drive gear wheel driven by at least one drive motor. The bearing points or bearing pins of the pivoting bridge accordingly do not have to transmit any drive torque and are not subjected to any torque load so that more precise running and more precise positioning is possible.
