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.

The invention relates to a clamping device with a fixed clamping jaw (1), a movable clamping jaw (2) and a drive for adjusting the movable clamping jaw (2) relative to the fixed clamping jaw (1), wherein the drive is a threaded spindle (7) and a reinforcing mechanism ( 8) for enhancing the clamping force. In order to allow optimal accessibility with high clamping precision, the threaded spindle (7) as a telescopic spindle and the reinforcing mechanism (8) for exerting a tensile force on the movable clamping jaw (2) is formed.
