Abstract
Auf einer Vorrichtung zum Schleifen des Profils eines rotierenden Werkstücks (5) wird ein axial und quer zur Werkstückspindel (4) verschieblich auf einem Schwenktisch (6) angeordnetes rotierbares Werkstück (5) erfindungsgemäß vor dem Schleifen gegenüber einer Schwenktischachse (D) so positioniert, dass der Mittelpunkt eines kreisbogenförmigen mit hoher Präzision zu schleifenden Werkstückprofilabschnitts (7) auf der Schwenkachse (D) des Schwenktisches (6) zu liegen kommt. Die hierdurch erreichte Reduktion der Anzahl simultaner Achsbewegungen beim Schleifen dieses Profilabschnitts (7) auf nur eine einzige Maschinenachse ermöglicht eine optimale Profilgenauigkeit.On a device for grinding the profile of a rotating workpiece (5), a rotatable workpiece (5) arranged displaceably on a pivot table (6) axially and transversely to the workpiece spindle (4) is positioned according to the invention before grinding relative to a pivot table axis (D) such that the center of a circular arc-shaped workpiece profile section (7) to be ground with high precision comes to lie on the pivot axis (D) of the pivoting table (6). The resulting reduction in the number of simultaneous axis movements during the grinding of this profile section (7) to only a single machine axis enables optimum profile accuracy.
Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Schleifen eines Profils eines Werkstücks.The The present invention relates to a method and an apparatus for grinding a profile of a workpiece.
Die Erfindung betrifft insbesondere das Schleifen von annähernd bzw. genau kreisbogenförmigen Werkstückprofilabschnitten. Die Erfindung ist geeignet zum Schleifen von Werkstückprofilabschnitten am Werkstückumfang mit einem Profilradius von weniger als 2 mm, die hinsichtlich ihrer Formabweichung Toleranzen von weniger als 4 – 5 μm unterworfen sind und stetig, d.h. tangential, in die an sie angrenzenden geraden oder bogenförmigen Konturabschnitte des Profils übergehen.The The invention particularly relates to the grinding of approximate or exactly circular arc Part profile sections. The invention is suitable for grinding workpiece profile sections on the workpiece circumference with a profile radius of less than 2 mm, which in terms of their Form deviation tolerances of less than 4 - 5 microns are subjected and steady, i.e. tangentially, in the adjacent to them straight or arcuate contour sections go over the profile.
Stand der TechnikState of technology
Es existiert auf dem Markt ein breites Angebot universeller vielachsiger numerisch gesteuerter Schleifmaschinen, welche eine hohe Fertigungsgenauigkeit aufweisen und zum Präzisionsschleifen des Profils rotierender Werkstücke aus hochfestem, gehärteten oder ungehärtetem Material für die verschiedensten Anwendungszwecke geeignet sind. Dieses Präzisionsschleifen unterliegt hohen Anforderungen an die Profilgenauigkeit und Oberflächenqualität der Werkstücke. Die Maschinen sind sich in ihrem Aufbau und der Konfiguration ihrer Bewegungsachsen zumeist sehr ähnlich.It exists on the market a wide range of universal multi-axis numerically controlled grinding machines, which a high manufacturing accuracy and for precision grinding of the Profile of rotating workpieces made of high-strength, hardened or uncured Material for the most diverse applications are suitable. This precision grinding is subject to high demands on the profile accuracy and surface quality of the workpieces. The machines are in their structure and the configuration of their axes of motion mostly very similar.

dem Maschinenständer
Alle Bewegungsachsen bzw. Bewegungen sind NC-gesteuert. Je nach dem herzustellenden Werkstückprofil sind während des Schleifens mehrere NC-Achsen, d.h. die X , Y, Z- und/oder B-Achse, gleichzeitig in Bewegung. Die unvermeidbaren achsgeschwindigkeits-, achsbeschleunigungs- und achslastabhängigen Lageabweichungen führen zu geringfügigen Konturabwei chungen des Werkstückprofils, die in Fällen extremer Toleranzanforderungen jedoch die zulässige Grenze übersteigen.All Motion axes or movements are NC-controlled. Depending on the workpiece profile to be produced are during grinding several NC axes, i. the X, Y, Z and / or B axis, simultaneously moving. The unavoidable axle speed, axle acceleration and axle load dependent Position deviations lead to slight Contour deviations of the workpiece profile, in cases extreme tolerance requirements, however, exceed the permissible limit.
Darstellung der Erfindungpresentation the invention
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, mittels welchen sich unerwünschte Profilabweichungen am bearbeiteten Werkstück reduzieren lassen.It is therefore an object of the present invention, a method and to provide a device of the type mentioned by means of which is undesirable Allow profile deviations to be reduced on the machined workpiece.
Diese Aufgabe wird durch ein Verfahren und eine Vorrichtung gemäss den Patentansprüche 1 bzw. 8 gelöst.These The object is achieved by a method and a device according to claims 1 or 8 solved.
Im erfindungsgemässen Verfahren bzw. in der erfindungsgemässen Vorrichtung zum Schleifen eines annähernd kreisbogenförmigen oder eines kreisbogenförmigen Profilabschnitts eines Werkstücks auf einer Schleifmaschine wird das Werkstück auf eine Werkstückspindel gespannt, wobei die Werkstückspindel auf einem um eine Schwenkachse schwenkbaren Schwenktisch angeordnet ist. Das aufgespannte Werkstück wird zusammen mit der Werkstückspindel in eine Position verschoben, in welcher der Mittelpunkt des Profilabschnitts zur Schwenkachse des Schwenktischs einen Abstand aufweist, welcher minimiert ist. Anschliessend wird dieser Profilabschnitt geschliffen.in the invention Method or in the inventive device for grinding a nearly circular or a circular arc Profile section of a workpiece On a grinding machine, the workpiece is placed on a workpiece spindle cocked, with the workpiece spindle arranged on a pivotable about a pivot axis pivoting table is. The clamped workpiece gets along with the workpiece spindle moved to a position in which the center of the profile section to the pivot axis of the pivot table has a distance which is minimized. Subsequently, this profile section is ground.
Die Erfindung macht sich zunutze, dass insbesondere bei hohen Verfahrgeschwindigkeiten und Beschleunigungen der an der Erzeugung eines Werkstückprofils beteiligten Bewegungsachsen die Profilabweichungen am kleinsten werden, wenn möglichst nur eine einzige NC-Achse bewegt werden muss, um einen mit extremer Genauigkeit zu fertigenden Profilabschnitt zu erzeugen.The Invention makes use of that, especially at high speeds and accelerating the production of a workpiece profile involved motion axes the profile deviations smallest if possible Only a single NC axis needs to be moved to one with extreme Accuracy to produce profile section to produce.
Die erfindungsgemässe Anordnung der Bewegungsachsen auf der Maschine erlaubt, das Werkstück mit hoher Genauigkeit so zu positionieren, dass kritische kreisbogenförmige Werkstückprofilabschnitte mittels Schwenkung als einziger Achsbewegung erzeugt werden können. Die Schwenkung wird dabei mittels eines Schwenktisches erzeugt, auf welchem die Werkstückspindel angeordnet ist.The invention Arrangement of the axes of movement on the machine allows the workpiece with high Accuracy positioning so that critical arcuate workpiece profile sections can be generated by pivoting as the only axis movement. The Pivoting is generated by means of a swivel table, on which the workpiece spindle is arranged.
Ist der zu schleifende Werkstückprofilabschnitt nicht genau kreisbogenförmig, so wird der Abstand eines ungefähren Mittelpunkts des Profilabschnitts zur Schwenkachse minimiert bzw. es wird die Position des Werkstücks so eingestellt, dass die Beschleunigungen der übrigen, nun doch am Schleifen beteiligten Maschinenachsen minimiert sind.If the workpiece profile section to be ground is not exactly circular-arc-shaped, then the Ab the position of the workpiece is set such that the accelerations of the other machine axes involved in the grinding are minimized.
