Abstract

Die Erfindung betrifft eine Spannvorrichtung mit einer festen Spannbacke (1), einer beweglichen Spannbacke (2) und einem Antrieb zur Verstellung der beweglichen Spannbacke (2) gegenüber der festen Spannbacke (1), wobei der Antrieb eine Gewindespindel (7) und einen Verstärkungsmechanismus (8) zur Verstärkung der Spannkraft enthält. Um eine optimale Zugänglichkeit bei gleichzeitig hoher Spannpräzision zu ermöglichen, ist die Gewindespindel (7) als Teleskopspindel und der Verstärkungsmechanismus (8) zur Ausübung einer Zugkraft auf die bewegliche Spannbacke (2) ausgebildet.
