Abstract

Die Erfindung betrifft eine Spanneinheit (1) mit Spannzylinder (2) zum Spannen von Werkstücken, die auf einer Aufnahmeplatte (6) festsetzbar ist. Um die Spanneinheit (1) auf einfache Weise auf einer Aufnahmeplatte oder dergleichen auch bei einer sehr engen Bestückung mit Werkstücken festsetzen zu können, ist die erfindungsgemäße Spanneinheit (1) dadurch gekennzeichnet, dass der Spanneinheit (1) an ihrer Unterseite ein Zapfen (5) zugeordnet ist, der in eine Aufnahmebohrung (7) der Aufnahmeplatte (6) einführbar ist und in dieser mittels einer Druckschraube (9), die in einer in der Aufnahmeplatte (6) geneigt eingebrachten Seitenbohrung (8) geführt ist, festsetzbar ist.

The invention relates to a clamping unit (1) with clamping cylinder (2) for clamping workpieces, which can be fixed on a receiving plate (6). In order to fix the clamping unit (1) in a simple manner on a receiving plate or the like even with a very tight assembly with workpieces, the clamping unit (1) according to the invention is characterized in that the clamping unit (1) on its underside a pin (5) is assigned, which in a receiving bore (7) of the receiving plate (6) is insertable and in this by means of a pressure screw (9) which is guided in a in the receiving plate (6) inclined introduced side bore (8) can be fixed.
