Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Bearbeitung von Zapfenkreuzen oder ähnlichen Werkstücken mit rotationssymmetrischen Bereichen nach dem Oberbegriff des Patentanspruchs 1. Derartige Werkstücke, beispielsweise Armaturen oder Gelenksterne für Kardangelenke weisen mehrere Zapfen auf, deren Mantelflächen zu bearbeiten sind. Aus der
Es ist die Aufgabe der vorliegenden Erfindung ein Verfahren und eine Werkzeugmaschine anzugeben, womit Zapfenkreuze und ähnliche Werkstücke hochgenau gespannt und bearbeitet werden können.It is the object of the present invention to provide a method and a machine tool, with which journal crosses and similar workpieces can be clamped and processed with high precision.
Diese Aufgabe wird gelöst mit einem Verfahren nach Patentanspruch 1 und einer Werkzeugmaschine nach Patentanspruch 5. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This object is achieved by a method according to
Üblicherweise werden Zapfenkreuze zur Bearbeitung in einem Spannfutter aufgenommen und können um eine Schwenkachse, welche senkrecht zu einer Ebene durch die Längsachsen der Zapfen verläuft, geschwenkt werden. Zur Bearbeitung werden die Zapfen um ihre Längsachsen in Rotation versetzt. Nach Fertigstellung des ersten Zapfens wird das Werkstück zum nächsten zu bearbeitenden Zapfen weiter getaktet, bei Tripoden beispielsweise um 120°. Gemäß einem vorteilhaften Aspekt der Erfindung werden die Werkstücke in einer Bohrung auf einem Spreizelement aufgenommen und beim Spannen relativ zur Schwenkachse zentriert. Im Folgenden wird die Erfindung an Hand eines Ausführungsbeispiels näher erläutert.Usually spiked crosses are accommodated for machining in a chuck and can be pivoted about a pivot axis, which runs perpendicular to a plane through the longitudinal axes of the pins. For machining, the pins are set in rotation about their longitudinal axes. After completion of the first pin, the workpiece is further clocked to the next pin to be machined, for tripods, for example, by 120 °. According to an advantageous aspect of the invention, the workpieces are received in a bore on a spreader and centered during clamping relative to the pivot axis. The invention will be explained in more detail below with reference to an exemplary embodiment.
