Abstract

Es wird eine elektrimechanische Spannvorrichtung mit hydraulischer Unterstützung beschrieben. Ein von einem Elektromotor (25) angetriebenes Schubgetriebe (26), verschiebt zwei Spannbacken (11, 13) entlang einer Führungseinrichtung (12) gegeneinander. Die eine Spannbacke (13) ist in zwei (16, 17) gegeneinander verschiebbare Teilbacken (16, 17) geteilt. Zwischen (20) den Teilbacken ist eine Kammer (20) für die Aufnahme von Druckmittel gebildet. Die erste Teilbacke (16) ist entlang der Führungseinrichtung (12) verschiebbar und gegenüber dieser verriegelbar. Eine Teilbacke (17) ist mit einem ersten Zylinder (33) versehen, der mit dem Antrieb des Schubgetriebes (26) gekoppelt ist. Zum Schliessen der Spannvorrichtung zieht das Schubgetriebe in einem ersten Schritt die Teilbacken (16, 17) gegen die andere Spannbacke (11), in einem zweiten Schritt fördert das Schubgetriebe (26) bei gegenüber der Führungseinrichtung (12) verriegelter erster Teilbacke (16) Druckmittel aus dem ersten Zylinder (33) in die Kammer (20) zwischen den beiden Teilbacken (16, 17). Zum Öffnen der Spannvorrichtung zieht ein zweiter, zwischen den beiden Teilbacken (16, 17) angeordneter Zylinder (41) in einem ersten Schritt bei gegenüber der Führungseinrichtung (12) verriegelter erster Teilbacke (16) die Teilbacken (16, 17) gegeneinander, danach drückt das Schubgetriebe (26) in einem zweiten Schritt bei von der Führungseinrichtung (12) entriegelter erster Teilbacke (16) die mit ihm gekoppelte Teilbacke (17) unter Mitnahme der anderen Teilbacke (16) in Öffnungsrichtung.
