Abstract
Description
Die Erfindung betrifft einen Doppelschrägschieberkopf und ein Verfahren zur Bearbeitung von Ventilbohrungen gemäß Oberbegriff der Ansprüche 1 und 2.The The invention relates to a Doppelschrägschieberkopf and a method for machining valve bores according to the preamble of claims 1 and Second
Die Ventilbearbeitung an Zylinderköpfen wird derzeit zum einen auf Bearbeitungszentren zum anderen auf Sondermaschinen respektive Transferstraßen durchgeführt.The Valve processing on cylinder heads is currently on the one hand on machining centers on the other on special machines respectively transfer roads carried out.
Bei der flexiblen Fertigung auf Zentren werden für die einzelnen Bearbeitungsschritte die aufeinander folgenden Werkzeuge sequenziell und automatisch in die Hauptspindel ein- und ausgewechselt. Dabei besteht ganz nebenbei die Möglichkeit, flexibel auf unterschiedliche Werkstücktypen bis hin zur Losgröße „ein Stück" zu reagieren, indem auf die dem Werkstücktyp zugeordneten Werkzeuge zurückgegriffen wird.at The flexible manufacturing centers will be responsible for the individual processing steps the sequential tools sequentially and automatically changed into the main spindle and replaced. It is incidentally the possibility, to respond flexibly to different workpiece types up to batch size "one piece" by on the workpiece type recourse to assigned tools becomes.
Soll
die Fertigung hingegen auf Transferstraßen oder Sondermaschinen mit
der Vorgabe der Verwendung von Doppelschrägschieberköpfen, wie beispielsweise in
der
Der Erfindung liegt die Aufgabe zu Grunde, einen Doppelschrägschieberkopf und ein Verfahren zur Bearbeitung von Ventilbohrungen gemäß Oberbegriff der Ansprüche 1 und 2 vorzuschlagen, bei dem man auch auf Transferstraßen und Sondermaschinen einen automatischen Werkstück-Typenwechsel vollziehen kann.Of the Invention is based on the object, a Doppelschrägschieberkopf and a method for machining valve bores according to the preamble the claims 1 and 2 to propose, in which one also on transfer roads and Special machines carry out an automatic workpiece type change can.
Dazu wird der im Anspruch 1 beschriebene Doppelschieberkopf bzw. das im Anspruch 2 beschriebene Verfahren vorgeschlagen.To is described in claim 1 double slide head or the proposed in claim 2.
Es handelt sich dabei um einen mit der Hauptspindel der Maschine verbundenen Doppelschrägschieberkopf, welcher durch Interpolation mit der Z-Achse der Maschine mit einem Werkzeug zum Fertigbearbeiten des Ventilsitzes wie bereits beschrieben die unterschiedlichen Fasen der Ventilbohrungen zu bewerkstelligen hat. Dieser Doppelschrägschieberkopf ist kombiniert mit einem Ventilführungswerkzeug, welches über eine automatisch zu betätigende Werkzeugschnittstelle ebenfalls in der Hauptspindel der Maschine sitzt. Die automatisch zu betätigende Werkzeugschnittstelle eröffnet zum einen die primär notwendige Möglichkeit, Werkzeuge unterschiedlichen Durchmessers bzw. unterschiedlicher Länge einzuwechseln, zum anderen bietet sie den Vorteil, Werkzeuge für die Bearbeitung eines Pilotdurchmessers, welcher eine mechanische Werkzeugführung zu umgehen hilft, einwechseln zu können.It this is one connected to the main spindle of the machine Double helical slide head, which by interpolation with the Z-axis of the machine with a Tool for finishing the valve seat as already described to accomplish the different chamfers of the valve bores Has. This double bevel pusher head is combined with a valve guide tool, which over an automatically operated Tool interface also in the main spindle of the machine sitting. The automatically operated Tool interface opened on the one hand the primary necessary possibility Load tools of different diameters or different lengths, on the other hand, it offers the advantage of tools for machining a pilot diameter, which helps to bypass a mechanical tool guide to be able to.
