Description

zugszeichen wie in Fig. 1 verwendet worden. Wie Fig.2 erkennen läßt, sind die Innenspannbacken7 auf den schrägen Führungsflächen 6 entgegen der Kraft der Federn 9 verschoben worden, und zwar werden sie so lange verschoben, bis die Futterplatten 8 der Innenspannbacken 7 die Winkelprofile 13 mit ihren Außenflächen fest gegen die Futterplatten 12 der Spannbrücke 11 drücken. Da es sich nach Fig.2 um zwei Winkelprofile 13 gleicher Abmessungen handelt, bleibt das Spannbacken-Führungsstück 3 in der Symmetriemitte stehen.Marks as in Fig. 1 have been used. As can be seen in FIG. 2, the inner clamping jaws 7 have been moved on the inclined guide surfaces 6 against the force of the springs 9, and they are shifted until the lining plates 8 of the inner clamping jaws 7 hold the angle profiles 13 with their outer surfaces firmly against the lining plates 12 the clamping bridge 11 press. Since, according to FIG. 2, there are two angle profiles 13 of the same dimensions, the clamping jaw guide piece 3 remains in the center of symmetry.

Haben die Winkelprofile 13 ungleiche Abmessungen oder wird nur ein Winkelprofil 13 eingespannt, so passen sich die Innenspannbacken 7 in jedem Falle dem oder den einzuspannenden Werkstücken) an.If the angle profiles 13 have unequal dimensions or only one angle profile 13 is clamped, so the internal clamping jaws 7 fit the work piece (s) to be clamped in any case) on.

Fig.3 zeigt die Einspannvorrichtung mit nur einem eingespannten Winkelprofil 13. In diesem Falle hat sich das Spannbacken-Führungsstück 3 um das Maß der Schichtstärke des Winkelprofils 13 seitlich aus der Symmetrieebene verschoben. Fig.3 läßt eindeutig erkennen, daß sich die Einspannvorrichtung jedem Einspannfall selbsttätig anpaßt. Würde auf der rechten Seite in Fig. 3 ein kleineres Winkelprofil 13 als auf der linken Seite eingespannt, so würde die seitliche Verschiebung des Spannbacken-Führangsstücks3 der Differenz der Schichtstärken der beiden unterschiedlichen Winkelprofile 13 entsprechen. In jedem Falle aber wird die Einspannvorrichtung in Spannstellung zwangläufig starr verriegelt, und zwar durch den Druckmitteldruck, der auf den Spannstößel 1 einwirktFig.3 shows the jig with only a clamped angle profile 13. In this case, the clamping jaw guide piece 3 has to the measure of the layer thickness of the angle profile 13 shifted laterally out of the plane of symmetry. Fig.3 leaves clearly recognize that the clamping device automatically adapts to each clamping case. Would on the right side in Fig. 3 a smaller angle profile 13 than clamped on the left side, so The lateral displacement of the clamping jaw guide piece 3 would be the difference in the layer thicknesses the two different angle profiles 13 correspond. In any case, however, the jig Inevitably rigidly locked in the clamping position, through the pressure of the pressure medium on the clamping ram 1 acts
