Description
Die Erfindung betrifft eine Einrichtung zur Kompensation der Winkelabweichungen einer horizontalen Spindeleinheit eines Bearbeitungszentrums oder eines Bohrwerkes.The The invention relates to a device for compensating the angular deviations a horizontal spindle unit of a machining center or a boring machine.
Aus
dem Stand der Technik ist bekannt, dass Verformungen an Werkzeugmaschinen
nach der spanenden Bearbeitung zu Maß-, Form- oder Lageabweichungen
am Werkstück
führen.
Ein spezifisches Problem an horizontalen Bearbeitungszentren und
Bohrwerken ist die lastabhängige
Durchbiegung der Spindeleinheit in Abhängigkeit von ihrer Auskraglänge und
vom Gewicht der daran befestigten Bearbeitungseinheit. Diese Durchbiegung
führt zu
Winkelabweichungen des Werkzeuges, die zu kompensieren sind. In
Die Aufgabe der Erfindung besteht deshalb darin, eine Einrichtung zur Kompensation der Winkelabweichungen einer horizontalen Spindeleinheit eines Bearbeitungszentrums oder eines Bohrwerkes vorzuschlagen, die die Winkelabweichungen durch ein hydrostatisches Lager während des Betriebes kompensiert. Die Lösung des vorhandenen Problems besteht in einer Einrichtung mit den Merkmalen des Patentanspruchs. Die neue Einrichtung hat den Vorteil, dass verschiedene Winkelabweichungen des Werkzeuges während des Betriebes eines Bearbeitungszentrums oder eines Bohrwerkes kompensierbar sind und somit eine qualitätsgerechtere Herstellung von Werkstücken erfolgt. Das Prinzip der hydrostatischen Lagerung gewährleistet eine verschleißfreie, schwingungsdämpfende und platzsparende Führung des Spindelkastenschlittens.The The object of the invention is therefore to provide a device for Compensation of the angular deviations of a horizontal spindle unit to propose a machining center or boring mill, the angular deviations through a hydrostatic bearing during the Operation compensated. The solution The existing problem is a device with the features of the claim. The new facility has the advantage that different angular deviations of the tool during the operation of a machining center or a boring mill can be compensated and thus a better quality Production of workpieces he follows. The principle of hydrostatic bearing ensures a wear-free, antivibration and space-saving leadership of the spindle box carriage.
Die Erfindung soll am Beispiel einer Einrichtung in einem Bearbeitungszentrum näher erläutert werden. Hierzu zeigen die zugehörigen Zeichnungen inThe The invention is based on the example of a device in a machining center be explained in more detail. For this show the associated Drawings in

Zur
Kompensation der Winkelabweichungen der horizontalen Spindeleinheit
Winkelabweichungen, die durch Bearbeitungskräfte entstehen, können ebenfalls kompensiert werden. Die auftretenden Bearbeitungskräfte sind als feste Werte bei der Erfassung der Daten eingegangen. Auch für den Fall, dass die horizontale Spindeleinheit eingefahren ist, werden Winkelkompensationen vorgenommen, da sich die Spindeleinheit auf der dem Werkzeug entgegengesetzten Spindelseite unter der eigenen Last durchbiegt. Diese Verformung der Spindeleinheit hat auch einen Einfluss auf die Lage des werkzeugseitigen Spindelendes. Die neue Einrichtung kann in beliebigen Werkzeugmaschinen mit horizontal verstellbarer Spindeleinheit, wie z. B. Fräs-, Dreh- und Schleifmaschinen, integriert werden.Angular deviations, the by machining forces can arise also be compensated. The occurring processing forces are as fixed values in the collection of the data received. Also in case that the horizontal spindle unit is retracted become angular compensations made because the spindle unit on the tool opposite Spindle side bends under its own load. This deformation of the Spindle unit also has an influence on the position of the tool side Spindle end. The new facility can be used in any machine tools horizontally adjustable spindle unit, such. Milling, turning and grinding machines, to get integrated.
