Abstract

Die Erfindung bezieht sich auf ein Spann- und Stützelement zum Halten von leicht verformbaren Werkstücken, mittels eines in einem Zylinder geführten Kolben, der hydraulisch beaufschlagt wird. Der Zylinderraum ist so gestaltet, daß zwischen Zylinder und Kolben eine Reibungskraft aufbaubar ist, die sich zur Haltekraft addiert. Der Hohlkolben wird in seinem mittleren Bereich mit einer verjüngten Wandung versehen, so daß durch einen separat aufgebauten Hydraulikdruck diese verformbare Wandung gegen die Innenwandung des Zylinders pressbar ist. In einer anderen Ausführung ist der Zylinder innen über einen vorgegebenen Bereich mit einer Aussparung versehen, so daß ein Druckraum ensteht. In diesem Bereich ist eine elastisch verformbare Hülse eingebracht. Durch einen Druckaufbau in dem Druckraum wird die Hülse gegen den Kolben gepresst.
