Abstract

Die Erfindung bezieht sich auf ein Zentrierspannelement zum Spannen von Werkstücken über Umlenkbolzen (4, 5), die zwischen einem Antriebselement und Zentrierspannschiebern (21) wirken. In einer zur Aufstellfläche des Elementes parallel liegenden Ebene sind in einem Gehäuse (1) in Ausnehmungen (2, 3) die Umlenkbolzen (4, 5) paarweise eingebracht, die mit Aussparungen (7) versehen sind, in denen Mitnahmeprismen (18, 19) angeordnet sind. Die Mitnahmeprismen (18, 19) besitzen Keilflächen(17), die in den Aussparungen (7) der Umlenkbolzen (4, 5) gleitend geführt sind. Die Umlenkbolzen (4, 5) werden von Kolben (13, 14) gesteuert, die in der gleichen Ebene jedoch quer zu den Umlenkbolzen (4, 5) angeordnet sind. Die Kraftübertragung erfolgt vom Kolben (13, 14) ausgehend über die Umlenkbolzen (4, 5) auf die Mitnahmeprismen (18, 19) und dann auf die mit den Mitnahmeprismen (18, 19) verbundenen Zentrierspannschieber(21), welche die Spannbacken (28, 29) bewegen.
