Abstract

Die Erfindung bezieht sich auf eine Spannvorrichtung zum Spannen von Werkstücken auf Maschinentischen. Ein hydraulisch betätigtes Spannkrafthalteelement, bei dem ein Spannbolzen (2) und dessen Haltekolben (5) annähernd senkrecht zu einander stehen und bei dem die Haltekraft über Elemente erzeugt wird, die mit Keilflächen (8) versehen sind die aufeinander gleiten, besitzt in seinem Haltekolben eine Keilnut (9), in deren Keilnutgrund eine Bohrung (10) eingebracht ist. Zwischen Keilnut und Bohrung ist ein Spalt (11) gebildet, so daß eine Führungsbahn entsteht. Ein Spannbolzen ist an einem Ende mit Keilflächen (14) versehen, die spitzwinklig auf einander zulaufen und in einem Nocken (15) enden. Der Spannbolzen bildet damit ein Führungsstück, das in die Führungsbahn des Haltekolbens einfügbar ist. Der Haltekolben ist über seiner Führungsbahn mit einer Keilschräge und im unteren Bereich mit einer Abflachung (16) versehen. Die an der Abflachung entstehenden Kanten (25,26) dienen zur Abstützung des Haltekolbens an der Zylinderwandung.
