Die Erfindung betrifft eine Vorrichtung zur Finishbearbeitung einer insbesondere gekrümmten Werkstückoberfläche, umfassend eine Antriebseinrichtung zur Erzeugung einer oszillierenden Schwenkbewegung eines Finishwerkzeughalters zum Halten eines Finishwerkzeugs, wobei eine Wirkfläche des Finishwerkzeugs nicht um eine konstruktiv realisierte Schwenkachse sondern um eine virtuelle Schwenkachse verschwenkbar ist.The invention relates to a device for finishing a particularly curved workpiece surface, comprising a drive device for generating an oscillating pivoting movement of a finishing tool holder for holding a finishing tool, wherein an effective surface of the finishing tool is not pivotable about a structurally realized pivot axis but about a virtual pivot axis.
Die finishende Bearbeitung eines Werkstücks ist ein auch als "Superfinishen" oder "Feinstbearbeitungsverfahren" bezeichnetes Verfahren zur Oberflächenbearbeitung eines Werkstücks. Bei diesem Verfahren wird ein abrasiv wirkendes Finishwerkzeug, beispielweise ein Finishstein oder ein Finishband, auf die zu bearbeitende Werkstückoberfläche gedrückt. Dabei rotiert die zu bearbeitende Werkstückoberfläche. Der Rotation der zu bearbeitenden Werkstückoberfläche wird eine oszillierende Bewegung überlagert, bei welcher sich das Finishwerkzeug und die zu bearbeitende Werkstückoberfläche in zu der Rotationsachse parallelen oder geneigten Richtungen relativ zueinander bewegen.Finish finishing of a workpiece is a method of surface machining a workpiece, also referred to as "superfinishing" or "microfinishing". In this process, an abrasive Finish tool, such as a finishing stone or a finishing tape, pressed on the workpiece surface to be machined. The workpiece surface to be machined rotates. The rotation of the workpiece surface to be machined is superimposed on an oscillating movement, in which the finishing tool and the workpiece surface to be machined move relative to each other in directions parallel or inclined to the axis of rotation.
Die finishende Bearbeitung von Werkstücken wird auch zur Bearbeitung von im Profil gekrümmten Werkstückoberflächen genutzt. Beispiele für Werkstücke mit solchen Werkstückoberflächen sind Wälzlagerringe oder Wälzlagerkörper. Gekrümmte Werkstückoberflächen werden mittels Finishwerkzeugen, insbesondere mittels Finishsteinen, bearbeitet, die um eine Schwenkachse hin- und herverschwenkt werden. Hierzu wird eine Antriebseinrichtung verwendet, die eine Antriebsbewegung erzeugt, welche mittels einer Getriebeeinrichtung in eine Schwenkbewegung des Finishwerkzeugs übersetzt wird. Vorrichtungen dieser Art werden auch als "Kreisschwinger" bezeichnet.The finishing machining of workpieces is also used to machine profile surfaces that are curved in profile. Examples of workpieces with such workpiece surfaces are roller bearing rings or bearing bodies. Curved workpiece surfaces are processed by means of finishing tools, in particular by means of finishing stones, which are pivoted back and forth about a pivot axis. For this purpose, a drive device is used, which generates a drive movement, which is translated by means of a transmission device into a pivoting movement of the finishing tool. Devices of this type are also referred to as "circular oscillators".

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Vorrichtung zu schaffen, welche eine möglichst einfache Bearbeitung von Werkstücken mit unterschiedlichen Geometrien ermöglicht.On this basis, the present invention has the object to provide a device which allows the simplest possible processing of workpieces with different geometries.
Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass die Antriebseinrichtung eine Koppel zum Antrieb des Finishwerkzeughalters umfasst, dass die Koppel jeweils verdrehbeweglich mit zwei gestellfest gelagerten Schwingen verbunden ist und dass eine Abstandseinstelleinrichtung zur Einstellung des Abstands der gestellfesten Lager der beiden Schwingen vorgesehen ist.This object is achieved in a device of the type mentioned in the present invention, that the drive means comprises a coupling for driving the finish tool holder, that the coupling is rotatably connected to two frame-mounted wings and that a Abstandseinstelleinrichtung for adjusting the distance of the frame-fixed bearings of the two Swing is provided.
Die erfindungsgemäße Antriebseinrichtung ermöglicht eine schnelle und einfache Verlagerung der virtuellen Schwenkachse, um die Vorrichtung an die Geometrie einer jeweils zu bearbeitenden Werkstückoberfläche anzupassen zu können. Die Verlagerung der virtuellen Schwenkachse geht mit der Einstellung des Abstands der gestellfesten Lager von zwei Schwingen einher. Diese Schwingen sind verdrehbeweglich mit einer Koppel verbunden, welche den Finishwerkzeughalter mit dem daran gehaltenen Finishwerkzeug antreibt.The drive device according to the invention allows a quick and easy displacement of the virtual Swivel axis to adapt the device to the geometry of each workpiece surface to be machined can. The displacement of the virtual pivot axis is accompanied by the adjustment of the distance of the frame-fixed bearings of two wings. These wings are rotatably connected to a coupling which drives the finish tool holder with the finishing tool held thereon.
Erfindungsgemäß wurde nicht nur erkannt, dass eine Viergelenkkette in Form einer Doppelschwinge als Antrieb für einen Finishwerkzeughalter geeignet ist, sondern auch, dass ein solches Getriebe eine besonders einfache Anpassung einer virtuellen Schwenkachse der Wirkfläche des Finishwerkzeugs ermöglicht.According to the invention, it has not only been recognized that a four-bar chain in the form of a double rocker is suitable as a drive for a finish tool holder, but also that such a gear allows a particularly simple adaptation of a virtual pivot axis of the effective surface of the finishing tool.
Wenn z.B. eine im Profil konvexe Werkzeugoberfläche bearbeitet werden soll, wird der Abstand der gestellfesten Schwingenlagern so eingestellt, dass er größer ist als der Abstand zwischen den koppelfesten Schwingenlagern.If e.g. a convex tool surface is to be processed in the profile, the distance between the frame-fixed swing bearings is set so that it is greater than the distance between the coupling-fixed swing bearings.
Wenn eine im Profil konkave Werkstückoberfläche bearbeitet werden soll, wird der Abstand der gestellfesten Schwingenlager so eingestellt, dass er kleiner ist als der Abstand zwischen den koppelfesten Schwingenlagern.If a concave workpiece surface is to be machined in the profile, the distance between the frame-fixed rocker bearings is set so that it is smaller than the distance between the coupling-fixed rocker bearings.
In einem speziellen Anwendungsfall ist es auch möglich, den Abstand zwischen den gestellfest Schwingenlagern so einzustellen, dass er gleich dem Abstand zwischen den koppelfesten Schwingenlagern ist, sodass im Profil geradlinige Werkstückoberflächen bearbeitet werden.In a special application, it is also possible to set the distance between the frame-fixed swingarm bearings so that it is equal to the distance between the coupling-fixed swingarm bearings, so that rectilinear workpiece surfaces are machined in the profile.
Es versteht sich, dass es für eine erfindungsgemäße Vorrichtung nicht erforderlich, jedoch bevorzugt ist, dass sämtliche der vorstehend beschriebenen Abstände eingestellt werden können, sodass die Bearbeitung von im Profil konvexer, konkaver und geradliniger Werkstückoberflächen ermöglicht wird.It is understood that it is not necessary for a device according to the invention, but it is preferred that all of the distances described above are set can be machined to allow profile convex, concave and straight workpiece surfaces to be machined.
Bei einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Abstandseinstelleinrichtung eine Spindel umfasst, mit einem ersten Gewinde, welches mit einem ersten Schwingenlagerträger für das gestellfeste Schwingenlager einer ersten Schwinge zusammenwirkt und mit einem zu dem ersten Gewinde gegenläufigen zweiten Gewinde, welches mit einem zweiten Schwingenlagerträger für das gestellfeste Schwingenlager einer zweiten Schwinge zusammenwirkt. Diese Abstandseinstelleinrichtung hat den Vorteil, dass lediglich ein Antrieb erforderlich ist, welcher auf die Spindel wirkt. Bei diesem Antrieb kann es sich um einen Handantrieb oder um einen motorischen Antrieb handeln. Wenn die Spindel in einer bestimmten Betätigungsrichtung verdreht wird, werden gleichzeitig beide gestellfeste Schwingenlager entlang der Spindelachse bewegt, und zwar zueinander gegenläufig, sodass eine Einstellung des Abstands der gestellfesten Lager der Schwingen lediglich mit einer Verlagerung der virtuellen Schwenkachse in Richtung auf die Koppel oder hierzu entgegengesetzt einhergeht und nicht zusätzlich auch mit einer seitlichen Verlagerung der virtuellen Schwenkachse.In a preferred embodiment of the invention it is provided that the Abstandseinstelleinrichtung comprises a spindle having a first thread which cooperates with a first swing bearing support for the frame-fixed swing bearing a first rocker and with a counter to the first thread second thread, which with a second swing bearing carrier for the frame-fixed swing bearing a second rocker cooperates. This Abstandseinstelleinrichtung has the advantage that only one drive is required, which acts on the spindle. This drive can be a hand drive or a motor drive. When the spindle is rotated in a certain direction of actuation, both frame-fixed rocker bearings are simultaneously moved along the spindle axis, namely counter to each other, so that an adjustment of the distance of the frame-fixed bearings of the rockers only with a displacement of the virtual pivot axis in the direction of the coupling or opposite thereto goes along and not additionally with a lateral displacement of the virtual pivot axis.
Bei einer weiteren bevorzugten Ausführungsform ist eine Andrückeinrichtung zum Andrücken der Wirkfläche des Finishwerkzeugs an die Werkstückoberfläche vorgesehen, insbesondere entlang einer radial zu der virtuellen Schwenkachse verlaufenden Achse. Auf diese Weise ist gewährleistet, dass die Wirkfläche des Finishwerkzeugs auch bei längeren Bewegungswegen (Bewegungsweg ist gleich Kreisbogenlänge zwischen den Umkehrpunkten der oszillierenden Schwenkbewegung) der Wirkfläche des Finishwerkzeugs an der Werkstückoberfläche anliegt.In a further preferred embodiment, a pressing device for pressing the active surface of the finishing tool is provided on the workpiece surface, in particular along an axis extending radially to the virtual pivot axis. In this way, it is ensured that the effective surface of the finishing tool even with longer movement paths (movement is equal arc length between the reversal points of the oscillating pivoting movement) of the effective surface of the finishing tool rests against the workpiece surface.
Insbesondere in Verbindung mit einer vorstehend beschriebenen Andrückeinrichtung ist es bevorzugt, dass das Finishwerkzeug längs einer Achse verschiebbar gelagert ist und dass die Achse bezogen auf die virtuelle Schwenkachse radial verläuft.In particular, in conjunction with a pressure device described above, it is preferred that the finishing tool is slidably mounted along an axis and that the axis extends radially relative to the virtual pivot axis.
Bei einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass die Antriebseinrichtung einen auf die Koppel wirkenden motorischen Antrieb umfasst und das eine hierdurch erzeugte Bewegung der Koppel von der Koppel auf die beiden Schwingen übertragen wird. Dies hat den Vorteil, dass eine Antriebsbewegung eines Motors in ein zentrales Bauteil der Viergelenkkette eingeleitet werden kann und asymmetrische Antriebskräfte vermieden werden können.In a further preferred embodiment, it is provided that the drive device comprises a motor drive acting on the coupling and that a movement of the coupling thus generated is transmitted from the coupling to the two wings. This has the advantage that a drive movement of an engine can be introduced into a central component of the four-bar chain and asymmetrical drive forces can be avoided.
Bei dem motorischen Antrieb handelt es sich vorzugsweise um einen Exzenterantrieb. Dieser hat den Vorteil, dass eine kontinuierliche Drehbewegung in einfacher Weise in eine oszillierende Schwingbewegung umgesetzt werden kann.The motor drive is preferably an eccentric drive. This has the advantage that a continuous rotational movement can be implemented in a simple manner in an oscillating oscillatory motion.
Bevorzugt ist es, dass der Finishwerkzeughalter oder die Koppel einen Aufnahmeraum zur Aufnahme eines Exzenters aufweist, welcher innerhalb des Aufnahmeraums in einer Richtung quer zu der Längserstreckung der Koppel bewegbar ist. Dies hat den Vorteil, dass eine Antriebsbewegung des Exzenterantriebs unmittelbar in eine oszillierende Bewegung der Koppel umgesetzt wird, welche im Wesentlichen tangential zu der zu bearbeitenden Werkstückoberfläche verläuft.It is preferred that the finishing tool holder or the coupling has a receiving space for receiving an eccentric, which is movable within the receiving space in a direction transverse to the longitudinal extent of the coupling. This has the advantage that a drive movement of the eccentric drive is converted directly into an oscillating movement of the coupling, which runs substantially tangentially to the workpiece surface to be machined.
Für eine möglichst reibungsarme Ausgestaltung des Exzenters ist es bevorzugt, dass der Exzenter eine durch eine Laufrolle gebildete Kontaktfläche aufweist. Diese wirkt vorzugsweise mit einer Wandung des vorstehend beschriebenen Aufnahmeraums zusammen.For a possible low-friction design of the eccentric, it is preferred that the eccentric one by one Has roller formed contact surface. This preferably cooperates with a wall of the receiving space described above.
Die Erfindung betrifft außerdem ein Verfahren zum Betreiben der vorstehend beschriebenen Vorrichtung. Vorteile und Ausgestaltungen des Verfahrens sind bereits vorstehend unter Bezugnahme auf die erfindungsgemäße Vorrichtung beschrieben worden.

Der motorische Antrieb 28 ist fest mit dem Gestell 12 verbunden.In order to generate a movement of the finishing
Die Antriebseinrichtung 26 umfasst außerdem eine Vierlenkkette. Dieses setzt sich aus dem Gestell 12, zwei Schwingen 32 und 34 sowie einer Koppel 36 zusammen.The
Die erste Schwinge 32 ist mittels eines ersten, gestellfesten Schwingenlagers 36 schwenkbar an dem Gestell 12 gelagert. Die zweite Schwinge 34 ist über ein zweites, gestellfestes Schwingenlager 38 schwenkbar an dem Gestell 12 gelagert. Die Schwingen 32 und 34 sind jeweils über koppelfeste Schwingenlager 40 und 42 verdrehbeweglich mit der Koppel 36 verbunden.The
Eine durch die koppelfesten Schwingenlager 40 und 42 verlaufende, gedachte Achse 44 verläuft im Wesentlichen parallel zu einer gedachten Achse 46, welche durch die gestellfesten Schwingenlager 36 und 38 hindurch verläuft. Die Koppel 36 dient zur Befestigung des Finishwerkzeughalters 14, welches sich während des Betriebs der Antriebseinrichtung 26 gemeinsam und gleichförmig mit der Koppel 36 bewegt.An
Die gestellfesten Schwingenlager 36 und 38 sind nicht fest mit dem Gestell 12 verbunden. Vielmehr ist (längs der Achse 46 gesehen) ein Abstand zwischen den gestellfesten Schwingenlagern 36 und 38 einstellbar. Hierfür ist eine Abstandeinstelleinrichtung 48 vorgesehen.The frame-fixed
Die Abstandseinstelleinrichtung 48 umfasst einen fest mit dem Gestell 12 verbundenen Spindelträger 50 zur Drehlagerung einer sich längs einer Spindelachse 52 erstreckenden Spindel 54. Vorzugsweise erstreckt sich die Spindelachse 52 parallel zu der Achse 46.The
Der Spindelträger 50 ist längs der Spindelachse 52 gesehen vorzugsweise auf derselben Höhe wie der Finishwerkzeughalter 14 angeordnet. Beidseits des Spindelträgers 50 weist die Spindel 54 Gewinde auf, nämlich ein erstes Gewinde 56 und ein zweites Gewinde 58. Die Gewinde 56 und 58 sind vorzugsweise gegenläufig und wirken jeweils mit einem zugeordneten Schwingenlagerträger 60, 62 zusammen. Die Schwingenlagerträger 60 und 62 sind längs einer Führung 64 verschieblich und zu der Spindelachse 52 parallel an dem Gestell 12 gelagert. Jeder der Schwingenlagerträger 60 und 62 dient zur Anordnung eines der gestellfesten Schwingenlagers 36 bzw. 38.The
Zum Antrieb der Spindel 54 ist ein Spindelantrieb 66 vorgesehen, bspw. für einen manuellen Antrieb in Form eines Handrads 68 oder auch in Form eines (nicht dargestellten) zu motorischen Spindelantriebs.To drive the

Zur finishenden Bearbeitung des Werkstücks 84 wird das Werkstück 84 um die Rotationsachse 86 in Drehrichtung angetrieben. Hierfür ist ein an sich schematisch dargestellter Drehantrieb 90 vorgesehen. Der Drehbewegung des Werkstücks 84 wird die mit dem Doppelpfeil des Finishwerkzeughalters 14 angedeutete Oszillationsbewegung 92 überlagert, welche tangential zu dem Profil der Werkstückoberfläche 88 verläuft.For finishing machining of the

Wie vorstehend bereits erläutert, ist der Abstand 94 zwischen den stellfesten Schwingenlagern 36 und 38 einstellbar. In
Es ist auch denkbar, den Abstand 94 so einzustellen, dass er gleich dem Abstand 96 ist. Für diesen Fall verlagert sich die virtuelle Schwenkachse 98 in einen unendlich von der Vorrichtung 10 entfernten Bereich. Dies ermöglicht die Verwendung der Vorrichtung 10 als Linearschwinger, bei welchem eine (ungekrümmte) Wirkfläche 20 eines Finishsteins 18 parallel zu einer im Profil ungekrümmten Werkstückoberfläche verschwenkt wird.It is also conceivable to set the
