KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Vorliegende Erfindung betrifft eine Einspannvorrichtung für Platten, welche sich gegenüber den bekannten Vorrichtungen dieser Art dadurch auszeichnet, daß das Werkstück innerhalb bestimmter Grenzen in jeder Lage sicher festgespannt werden kann.The present invention relates to a clamping device for plates which face each other the known devices of this type characterized in that the workpiece within certain limits in any position can be securely clamped. Fig. ι zeigt den Schnitt A -B durch- den Werkzeugtisch mit dem Befestigungselement, Fig. 2 den Grundriß dazu, und Fig. 3 das Exzenter.FIG. 1 shows the section A -B through the tool table with the fastening element, FIG. 2 shows the plan for this, and FIG. 3 shows the eccentric. Wie aus Fig. 2 ersichtlich, sind die in den Nuten des Werktisches verschiebbaren Befestigungsschrauben α im Durchmesser bedeutend kleiner als die Bohrungen des festzuspannenden Stückes b. Letzteres kann daher in eine beliebige Lage gebracht werden, und sobald die erforderliche Stellung des Stückes erreicht ist, werden die Exzenter c, welche in Fig. 2 nur an zwei Stellen eingezeichnet sind, in die Bohrungen des festzuspannenden Stükkes eingelegt, wobei die Schrauben a so weit zu verschieben sind, daß die erförderliche exzentrische Lage der Schraube α zur Bohrung erreicht wird. Das Stück sitzt nach dem Anziehen der Schrauben genau und sicher in der erwünschten Lage.As can be seen from FIG. 2, the fastening screws α displaceable in the grooves of the work table are significantly smaller in diameter than the bores of the piece b to be clamped. The latter can be placed in any position, therefore, and as soon as the required position of the track is reached, the eccentrics are c, which are located in only two places in Fig. 2, inserted in the holes of the to be clamped Stükkes, said coil a so are to be shifted far so that the necessary eccentric position of the screw α to the hole is reached. After the screws have been tightened, the piece sits precisely and securely in the desired position. Pat ε nt-An Spruch:Pat ε nt-An saying: Einspannvorrichtung für mit Bohrungen versehene Platten 0. dgl., dadurch gekennzeichnet, daß in den Spielraum zwischen den in den Nuten des Werktisches verschiebbaren Befestigungsschrauben (a) und den Bohrungen der Platte (b) Exzenter (c) eingelegt sind, welche die einzuspannende Platte innerhalb bestimmter Grenzen in der gewünschten Lage festhalten.Clamping the like for provided with bores plates 0.., Characterized in that there are inserted into the clearance between the sliding in the grooves of the work table fastening screws (a) and the bores of the plate (b) eccentric (c) disposed within the chucked disk hold certain limits in the desired position.
