Abstract

Die Erfindung betrifft eine Spannvorrichtung zum Spannen von Gegenständen, insbesondere Werkstücken (30), Werkzeugen oder Vorrichtungen, in Bearbeitungsmaschinen, mit einer Basis (17) mit Befestigungsmitteln (18,35) zum Befestigen der Spannvorrichtung an einem Maschinentisch der Bearbeitungsmaschine und mit einem zum Spannen des Gegenstandes auf die Basis zu bewegbaren Spanneisen (13). Um Verformungen infolge von durch die Spannkräfte in den Maschinentisch eingeleitete Biegekräfte zu vermeiden, ist die Spannvorrichtung dadurch gekennzeichnet, daß die Basis (17) ein Auflager (20) für den Gegenstand aufweist, derart, daß der Gegenstand beim Spannen zwischen dem Spanneisen (13) und dem Auflager (20) gespannt ist.

Figure imgaf001
The invention relates to a clamping device for clamping objects, in particular workpieces (30), tools or devices, in processing machines, with a base (17) with fastening means (18,35) for securing the clamping device to a machine table of the processing machine and with a for clamping of the object on the base to movable clamps (13). In order to avoid deformations as a result of bending forces introduced into the machine table by the clamping forces, the clamping device is characterized in that the base (17) has a support (20) for the object, such that the object is clamped between the clamping iron (13). and the support (20) is tensioned.
