Abstract

Bei der Vorrichtung zum Aufspannen von Werkstücken aufWerkzeugmaschinentischen, insbesondere als Rundfutter auf Drehmaschinen mit einer Spannplatte werden die Nuten durch eine Spirale gebildet, deren Windungen von einem festen Punkt ausgehen. In vorteilhafter Weise ist in diesem Punkt die Unterdruckquelle angeschlossen. Hierdurch ist es beim Aufspannen eines Wekstückes grundsätzlich nur noch erforderlich, an einer Stelle eine kleine elastische Dichtung einzusetzen, um den Teil der spiralförmigen Nut von der Unterdruckquelle zu trennen, der nicht mehr im Projektions­ bereich des Wekstückes liegt. In the device for clamping workpieces on machine tool tables, especially as round chucks The grooves are machined on lathes with a clamping plate formed by a spiral, the turns of one going out fixed point. It is advantageous in this Point the vacuum source is connected. This is it basically only when clamping a workpiece required a small elastic seal at one point insert the part of the spiral groove from the Separate vacuum source that is no longer in the projection area of the workpiece.
