Abstract
The invention relates to a steady rest for clamping and/or for holding a workpiece (W) on a machine tool, comprising three holding members (3, 4, 5) mounted in a housing (2) and displaceable in a common plane, two of which are designed as two-armed levers pivotably supported in the housing (2), and the central holding member (5) is guided in a straight line. The two outer holding members (3, 4) are kinematically connected respectively to the central holding member (5) via an angle lever (10, 11) so that with an opening movement of the central holding member (5) the outer holding members (3, 4) are pivoted apart from one another. The angle levers (10, 11) are linked rotatably onto the central holding member (5), respectively the one leg of the angle levers (10, 11) being connected to the associated outer holding member (3, 4), and the other leg being connected to the housing (2) by means of gate/pin arrangements.
