Description
Die Erfindung betrifft ein Verfahren zur Ankopplung eines Honwerkzeugs an eine Honspindel nach den Oberbegriff des Anspruchs 1, eine dazu geeignete Honspindel nach den Oberbegriff des Anspruchs 8 sowie ein dazu geeignetes Honwerkzeug nach den Oberbegriff des Anspruchs 13. Beispiele hierfür sind aus der
Honwerkzeuge werden zur präzisen Bearbeitung von vorzugsweise zylindrischen Innen- oder Außenflächen eingesetzt und werden zu diesem Zweck an eine Honspindel angekoppelt, die typischerweise Teil einer Honmaschine ist. Von der Honspindel können Kräfte und Drehmomente auf das Honwerkzeug übertragen werden, um die gewünschte Oberflächenbearbeitung durchzuführen.Honing tools are used for precise machining of preferably cylindrical inner or outer surfaces and are coupled for this purpose to a honing spindle, which is typically part of a honing machine. From the honing spindle forces and torques can be transferred to the honing tool to perform the desired surface treatment.
Für einen flexiblen Einsatz der Honeinrichtung ist es bekannt, eine Kupplungseinrichtung zwischen der Honspindel und dem Honwerkzeug vorzusehen, die ein Auswechseln des Honwerkzeugs ermöglicht. Dabei ist zu beachten, dass typische Honwerkzeuge an einem der Honspindel abgewandten Ende zumindest einen Schneidstoffkörper aufweisen, der während der Oberflächenbearbeitung mit einer Andruckkraft auf die Oberfläche gepresst wird. Die Andruckkraft wird typischerweise von einer in der Honspindel vorgesehenen Zustellstange auf eine Druckstange im Honwerkzeug und von dort auf den Schneidstoffkörper übertragen. In diesem Fall muss eine kraftübertragende Verbindung zwischen der Zustellstange und der Druckstange ebenfalls lösbar ausgeführt sein, um ein Auswechseln des Honwerkzeugs zu ermöglichen.For a flexible use of the honing device, it is known to provide a coupling device between the honing spindle and the honing tool, which allows a replacement of the honing tool. It should be noted that typical honing tools on an end facing away from the honing spindle have at least one cutting material body which is pressed onto the surface during the surface treatment with a pressure force. The pressure force is typically transmitted from a provided in the honing spindle feed rod on a push rod in the honing tool and from there to the cutting material body. In this case, a force-transmitting connection between the feed rod and the push rod must also be made detachable to allow replacement of the honing tool.
Um die bei einem Honvorgang geforderte Präzision der Oberflächenbearbeitung gewährleisten zu können, werden hohe Anforderungen an die lösbare Verbindung zwischen Honspindel und Honwerkzeug gestellt.In order to ensure the required during a honing process precision of surface processing, high demands are placed on the detachable connection between the honing spindle and honing tool.
Diese Anforderungen beziehen sich insbesondere auf die Rundlauftoleranz des Honwerkzeugs gegenüber einer Honspindelmittelachse. Um eine hohe Rundlauftoleranz sicherzustellen, ist es bekannt, die Honspindel endseitig mit einer zylindrischen, präzisionsgeschliffenen Oberfläche auszuführen und ein Spannfutter mit einer korrespondierenden Bohrung vorzusehen, die in der Art einer Steckverbindung miteinander verbunden werden können. Um eine zuverlässige Steckverbindung zu gewährleisten, kann eine Innenwandung der Bohrung im Spannfutter mittels einer im Spannfutter integrierten hydrostatischen Spanneinrichtung deformiert werden, so dass das Honwerkzeug zentriert an der Honspindel festgelegt werden kann. Eine Kopplung der Druckstange mit der Honspindel wird bei einem bekannten Honwerkzeug durch einen Bajonettverschluss verwirklicht. Zur Ankopplung des Honwerkzeugs muss zunächst der Bajonettverschluss der Druckstange manuell von einem Bediener verriegelt werden, anschließend kann das Honwerkzeug durch Betätigen der hydrostatischen Spanneinrichtung an der Honspindel festgelegt werden.These requirements relate in particular to the concentricity tolerance of the honing tool with respect to a Honspindelmittelachse. In order to ensure a high concentricity tolerance, it is known to carry out the honing spindle end with a cylindrical, precision ground surface and to provide a chuck with a corresponding bore, which can be connected to each other in the manner of a plug connection. To ensure a reliable plug connection, an inner wall of the bore in the chuck can be deformed by means of a hydrostatic clamping device integrated in the chuck so that the honing tool can be centered on the honing spindle. A coupling of the push rod with the honing spindle is realized in a known honing tool by a bayonet lock. To connect the honing tool, the bayonet lock of the push rod must first be manually locked by an operator, then the honing tool can be fixed to the honing spindle by actuating the hydrostatic clamping device.
Eine Aufgabe der Erfindung besteht darin, ein verbessertes Verfahren zur Ankopplung eines Honwerkzeugs an eine Honspindel zu schaffen. Insbesondere soll eine Automatisierung des Werkzeugwechsels ermöglicht werden. Weitere Aufgaben der Erfindung bestehen in der Schaffung einer verbesserten Honspindel und eines verbesserten Honwerkzeugs, die insbesondere die Anwendung des Verfahrens ermöglichen.An object of the invention is to provide an improved method for coupling a honing tool to a honing spindle. In particular, an automation of the tool change is to be made possible. Other objects of the invention are to provide an improved honing spindle and an improved honing tool, which in particular allow the use of the method.
Diese und andere Aufgaben werden durch ein Verfahren mit den Merkmalen von Anspruch 1, eine Honspindel mit den Merkmalen von Anspruch 8 sowie ein Honwerkzeug mit den Merkmalen von Anspruch 13 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben. Der Wortlaut sämtlichen Ansprüche wird durch Bezugnahme zum Inhalt der Beschreibung gemacht.These and other objects are achieved by a method having the features of
Gemäß einem ersten Aspekt der Erfindung ist ein Verfahren zur Ankopplung eines Honwerkzeugs an eine Honspindel vorgesehen, das folgende Schritte aufweist: Einsetzen des Honwerkzeugs in die Honspindel in eine Fügeposition, bei der eine Honwerkzeugmittelachse koaxial zur Honspindelmittelachse ausgerichtet ist; Arretieren des Honwerkzeugs an der Honspindel durch eine Betätigung einer der Honspindel zugeordneten Stelleinrichtung. Das Einsetzen des Honwerkzeugs in die Honspindel erfolgt zumindest in der Endphase der Einsetzbewegung normalerweise durch eine translatorische Bewegung parallel zur Honspindelmittelachse, bis die Funktionsposition erreicht ist.According to a first aspect of the invention, there is provided a method of coupling a honing tool to a honing spindle, comprising the steps of: inserting the honing tool into the honing spindle into a joining position in which a honing tool center axis is aligned coaxially with the honing spindle center axis; Locking the honing tool on the honing spindle by an actuation of an adjusting device associated with the honing spindle. The insertion of the honing tool into the honing spindle, at least in the final phase of the insertion movement, is normally effected by a translatory movement parallel to the honing spindle central axis until the functional position is reached.
Entscheidend bei der Durchführung des Verfahrens ist die Betätigung einer Stelleinrichtung, die der Honspindel zugeordnet ist, zur Arretierung des Honwerkzeugs. Die Stelleinrichtung tritt mit Kupplungsstrukturen des Honwerkzeugs und der Honspindel in einer Weise in Wechselwirkung, dass am Ende des Ankopplungsvorgangs eine präzise und stabile Ankopplung des Honwerkzeugs koaxial zur Honspindel gewährleistet ist. In Anbetracht des Umstands, dass jeweils das Honwerkzeug gewechselt wird, kann die Zuordnung der Kupplungseinrichtung zur Stelleinrichtung der Honspindel zu einer kostengünstigeren Gestaltung der Werkzeugspannung führen, da am Honwerkzeug eine teure Stelleinrichtung vermieden wird, ohne Abstriche bei der Präzision der Ankopplung des Honwerkzeugs an die Honspindel in Kauf nehmen zu müssen.Decisive in the implementation of the method is the actuation of an adjusting device, which is assigned to the honing spindle, for locking the honing tool. The adjusting device interacts with coupling structures of the honing tool and the honing spindle in such a way that a precise and stable coupling of the honing tool coaxially to the honing spindle is ensured at the end of the coupling process. In view of the fact that in each case the honing tool is changed, the assignment of the coupling device to the adjusting device of the honing spindle can lead to a more cost-effective design of the tool clamping, as the honing an expensive adjusting device is avoided without sacrificing the precision of the coupling of the honing tool to the honing spindle to have to accept.
Bevorzugt kann die Betätigung der Stelleinrichtung über eine Maschinensteuerung einer Honmaschine, der die Honspindel typischerweise zugeordnet ist, automatisch vorgenommen werden. Zudem wird durch die Zuordnung der Stelleinrichtung zur Honspindel eine Bereitstellung von Fremdkräften, beispielsweise in Form elektrischer oder hydraulischer Energie, zur Betätigung der Stelleinrichtung erleichtert, da derartige Fremdkräfte ohnehin für den Betrieb der Honmaschine zur Verfügung stehen. Das Honwerkzeug kann manuell von einem Benutzer oder automatisiert von einer Handhabungseinrichtung in die Fügeposition gebracht werden. Der weitere Fügevorgang zur Arretierung des Honwerkzeugs an der Honspindel kann manuell oder automatisiert ausgelöst und/oder durchgeführt werden.Preferably, the actuation of the adjusting device via a machine control of a honing machine to which the honing spindle is typically assigned, be made automatically. In addition, the provision of external forces, for example in the form of electrical or hydraulic energy, for actuating the adjusting device is facilitated by the assignment of the adjusting device to the honing spindle, since such foreign forces are available anyway for the operation of the honing machine. The honing tool can be manual by a user or automated be brought by a handling device in the joining position. The further joining process for locking the honing tool on the honing spindle can be triggered and / or performed manually or automatically.
In Ausgestaltung der Erfindung ist vorgesehen, dass die Stelleinrichtung längs der Honspindelmittelachse bewegt wird. Bei der Honspindel handelt es sich typischerweise um eine schlanke, säulenartige Struktur. Durch eine Gestaltung der Stelleinrichtung in der Art, dass die Stellbewegung längs der Honspindelmittelachse vorgenommen wird, kann gewährleistet werden, dass sich ein Querschnitt der säulenartigen Honspindel in einer Querschnittsebene orthogonal zur Honspindelmittelachse durch die Integration der Stelleinrichtung nicht verändert. Damit wird durch eine in Längsrichtung, insbesondere parallel zur Honspindelmittelachse bewegbare Stelleinrichtung eine automatisierbare und dennoch schlanke Gestaltung von Kupplungsstrukturen des Honwerkzeugs und der Honspindel ermöglicht.In an embodiment of the invention it is provided that the adjusting device is moved along the Honspindelmittelachse. The honing spindle is typically a slender, columnar structure. By designing the adjusting device in such a way that the adjusting movement is carried out along the Honspindelmittelachse, it can be ensured that a cross section of the columnar honing spindle does not change in a cross-sectional plane orthogonal to the Honspindelmittelachse by the integration of the adjusting device. Thus, an automatable and yet slender design of coupling structures of the honing tool and the honing spindle is made possible by a positioning device movable in the longitudinal direction, in particular parallel to the honing spindle center axis.
Erfindungsgemäß ist vorgesehen, dass die Arretierung des Honwerkzeugs an die Honspindel und die Ankopplung der Zustellstange an die Druckstange durch eine einzige Arbeitsbewegung der Zustellstange in Richtung des Honwerkzeugs bewirkt wird. Mit der Arbeitsbewegung der Zustellstange erfolgt auch die Stellbewegung der Stelleinrichtung. Die Translationsbewegung der Stelleinrichtung wird durch die Bewegung der Zustellstange bewirkt. Beispielsweise kann ein der Stelleinrichtung zugeordneter Energiespeicher, der für die Stellbewegung in Richtung des Honwerkzeugs vorgespannt ist, durch die Bewegung der Zustellstange in Richtung des Honwerkzeugs freigegeben werden und somit die Ankopplung des Honwerkzeugs an die Honspindel ermöglichen. Besonders bevorzugt findet die Stellbewegung der Stelleinrichtung wie auch die Bewegung der Zustellstange in Richtung des Honwerkzeugs statt. Dadurch lässt sich eine besonders vorteilhafte Gestaltung der Honspindel erreichen, da die Bewegungsrichtungen der Zustellstange und der Stelleinrichtung ähnlich oder identisch sind und keine Umlenkung von Bewegungen stattfinden muss, um eine zumindest abschnittsweise Kopplung einzelner Bewegungen zu gewährleisten. Durch die Stellbewegung der Stelleinrichtung kann zumindest eine Riegeleinrichtung für eine formschlüssige Verbindung des Honwerkzeugs mit der Honspindel betätigt werden. Die Riegeleinrichtung kann insbesondere für die Ausübung einer Kraft auf das Honwerkzeug gestaltet sein, die in Richtung der Honspindel gerichtet ist, um eine besonders feste und zuverlässige Ankopplung des Honwerkzeugs sicherzustellen. Bevorzugt ist die Riegeleinrichtung für eine formschlüssige Ankopplung des Honwerkzeugs an die Honspindel vorgesehen.According to the invention it is provided that the locking of the honing tool is effected on the honing spindle and the coupling of the feed rod to the push rod by a single working movement of the Zustellstange in the direction of the honing tool. With the working movement of the Zustellstange also takes place the adjusting movement of the adjusting device. The translational movement of the actuator is effected by the movement of the Zustellstange. For example, one of the actuator associated energy storage, which is biased for the adjusting movement in the direction of the honing tool, are released by the movement of the Zustellstange in the direction of the honing tool and thus enable the coupling of the honing tool to the honing spindle. Particularly preferably, the adjusting movement of the adjusting device takes place as well as the movement of the Zustellstange in the direction of the honing tool. This allows a particularly advantageous Achieve design of the honing spindle, since the directions of movement of the Zustellstange and the adjusting device are similar or identical and no diversion of movements must take place to ensure at least partially coupling individual movements. By the adjusting movement of the adjusting device, at least one locking device can be actuated for a positive connection of the honing tool with the honing spindle. The locking device may be designed in particular for the exercise of a force on the honing tool, which is directed in the direction of the honing spindle, to ensure a particularly firm and reliable coupling of the honing tool. Preferably, the locking device is provided for a positive coupling of the honing tool to the honing spindle.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass bei der Arretierung des Honwerkzeugs an der Honspindel eine Verriegelung einer Zustellstange der Honspindel an eine Druckstange des Honwerkzeugs vorgenommen wird. Die Verriegelung der Druckstange an die Zustellstange kann zeitgleich mit der Stellbewegung der Stelleinrichtung stattfinden oder auch zeitlich vor- oder nachgelagert sein. Bevorzugt kann die Verriegelung automatisch oder automatisierbar sein, so dass kein Zutun eines Bedieners notwendig ist, um das Honwerkzeug anzukoppeln. Damit kann ein vollständig automatisierter Ablauf der An- und Abkopplung von Honwerkzeugen an die Honspindel verwirklicht werden, wodurch sich eine größere Wirtschaftlichkeit für eine damit ausgerüstete Honmaschine verwirklichen lässt.In a further embodiment of the invention, it is provided that in the locking of the honing tool on the honing spindle, a locking of a feed rod of the honing spindle is made to a push rod of the honing tool. The locking of the push rod to the Zustellstange can take place at the same time with the adjusting movement of the adjusting device or also temporally upstream or downstream. Preferably, the lock can be automatic or automatable, so that no action of an operator is necessary to couple the honing tool. Thus, a fully automated sequence of coupling and decoupling of honing tools to the honing spindle can be realized, which can be realized a greater efficiency for a honing machine equipped with it.
Erfindungsgemäß ist vorgesehen, dass für die Ankopplung der Zustellstange an die Druckstange ausschließlich eine Translationsbewegung der Zustellstange in Richtung der Druckstange ausreicht, ohne dass eine Relativverdrehung zwischen Zustellstange und Druckstange zur Herstellung der kraftübertragenden Kopplung nötig ist. Dadurch wird eine Automatisierung der Ankopplung vereinfacht.According to the invention it is provided that only a translational movement of the Zustellstange in the direction of the push rod is sufficient for the coupling of the Zustellstange to the push rod, without a relative rotation between the feed rod and push rod for the production of force-transmitting coupling is necessary. This simplifies automation of the coupling.
Durch die Ankopplung der Zustellstange an die Druckstange wird eine spielfreie, auf Zug und Druck beanspruchbare Verkupplung dieser Teile geschaffen, so dass auch bei den für Honbearbeitungen charakteristischen axial oszillierenden Bewegungen der Honwerkzeuge jederzeit eine hochpräzise Steuerung der Honbearbeitung, insbesondere der Position der Honleisten und/oder der Anpresskraft der Honleisten an die zu bearbeitende Oberfläche, möglich ist.By coupling the Zustellstange to the push rod a play-free, claimable on train and pressure coupling of these parts is created, so that even with the honing operations characteristic axial oscillating movements of honing tools at any time a high-precision control honing, especially the position of the honing stones and / or the contact pressure of honing stones to the surface to be machined, is possible.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass bei einem Auftreffen der Zustellstange auf die Druckstange eine Bewegung einer Kupplungshülse relativ zur Zustellstange stattfindet, durch die zumindest ein Kupplungskörper, insbesondere in radialer Richtung, kraftübertragend an der Druckstange verriegelt wird. Die Kupplungshülse und/oder die Zustellstange kann mit zumindest einer Steuerfläche versehen sein, die durch die Relativbewegung zwischen Kupplungshülse und Zustellstange eine Bewegung eines Kupplungskörpers hervorruft, der seinerseits für eine formschlüssige Kopplung der Druckstange mit der Zustellstange vorgesehen ist. Der Kupplungskörper kann dabei vorzugsweise in einen hinterschnittenen Bereich, insbesondere eine Ausnehmung, an der Druckstange und/oder an der Zustellstange eingreifen. Bevorzugt sind der zumindest eine Kupplungskörper und die korrespondierende Ausnehmung derart gestaltet, dass eine Selbsthemmung der formschlüssigen Verbindung vorliegt. Bei einem Anstieg der über den Kupplungskörper und die Ausnehmung zu übertragenden Kräfte findet auch ein Anstieg der Verriegelungskräfte statt, so dass sich die Verbindung zwischen Kupplungskörper und Ausnehmung selbsttätig festzieht.In a further embodiment of the invention, it is provided that upon impact of the feed rod on the push rod, a movement of a coupling sleeve takes place relative to the Zustellstange, is locked by the at least one coupling body, in particular in the radial direction, force transmitting to the push rod. The coupling sleeve and / or the feed rod may be provided with at least one control surface, which causes a movement of a coupling body by the relative movement between the coupling sleeve and feed rod, which in turn is provided for a positive coupling of the push rod with the Zustellstange. The coupling body can preferably engage in an undercut area, in particular a recess, on the push rod and / or on the feed rod. Preferably, the at least one coupling body and the corresponding recess are designed such that there is a self-locking of the positive connection. With an increase in the forces to be transmitted via the coupling body and the recess, there is also an increase in the locking forces, so that the connection between the coupling body and the recess is self-tightening.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Relativbewegung der Kupplungshülse von einem Energiespeicher bewirkt wird, der durch eine Bewegung der Zustellstange relativ zur Stelleinrichtung freigegeben wird. Damit kann ein einfacher Aufbau der Kupplungsstruktur zwischen Zustellstange und Druckstange verwirklicht werden, der eine zuverlässige Verriegelung bzw. bei entgegengesetzter Bewegung der Zustellstange auch eine zuverlässige Entriegelung der Kupplungsstruktur sicherstellt. Als Energiespeicher kann vorzugsweise eine Schraubenfeder eingesetzt werden, die eine Speicherung eines zur Verund Entriegelung ausreichenden Energiebetrags in einem kleinen, zylindrischen Volumenabschnitt, der vorteilhaft zwischen Zustellstange und Kupplungshülse vorgesehen werden kann, ermöglicht.In a further embodiment of the invention, it is provided that the relative movement of the coupling sleeve is effected by an energy storage, which by moving the Zustellstange relative to the adjusting device is released. Thus, a simple structure of the coupling structure between the feed rod and the push rod can be realized, which ensures a reliable locking or with opposite movement of the Zustellstange also a reliable unlocking of the coupling structure. As energy storage can preferably be used a coil spring, which allows a storage of Verund unlocking sufficient amount of energy in a small, cylindrical volume portion, which can be advantageously provided between the feed rod and coupling sleeve allows.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass beim Ankoppeln der Zustellstange an die Druckstange eine abgedichtete, kommunizierende Verbindung zwischen Fluidkanälen der Zustellstange und der Druckstange hergestellt wird. Durch einen von der Honmaschine mit einem oder mehreren gasförmigen und/oder flüssigen Fluiden, insbesondere Honöl, versorgten Fluidkanal, der sich auch längs der Honspindel und des Honwerkzeugs erstreckt und typischerweise im Bereich der Honleisten in die Umgebung mündet, kann eine vorteilhafte Versorgung der Honleisten mit einem Kühl- und/oder Schmiermittel gewährleistet werden.In a further embodiment of the invention, it is provided that when coupling the Zustellstange to the push rod a sealed, communicating connection between fluid channels of the Zustellstange and the push rod is made. By one of the honing machine with one or more gaseous and / or liquid fluids, in particular honing oil, supplied fluid channel, which also extends along the honing spindle and the honing tool and typically opens into the area in the field of honing stones, can provide an advantageous supply of honing stones a coolant and / or lubricant can be ensured.
Gemäß einem weiteren Aspekt der Erfindung weist eine Honspindel einen Schaft zur Übertragung von Kräften und Drehmomenten auf einen Werkzeugkörper eines Honwerkzeugs auf. Dem Schaft ist eine Zustellstange zugeordnet, die für eine Bereitstellung einer Bearbeitungskraft auf eine Druckstange des Honwerkzeugs vorgesehen ist. Weiterhin ist endseitig am Schaft eine Werkzeugaufnahme vorgesehen, die für eine lösbare Ankopplung des Honwerkzeugs gestaltet ist, wobei der Werkzeugaufnahme zumindest eine Stelleinrichtung zugeordnet ist, die für eine Festlegung des Werkzeugkörpers am Schaft ausgebildet ist. Eine insbesondere automatisierbare Festlegung des Werkzeugkörpers des Honwerkzeugs am Schaft mittels einer dem Schaft zugeordneten Stelleinrichtung ermöglicht eine vorteilhafte Auswechslung von Honwerkzeugen, da alle die Ankopplung des Honwerkzeugs betreffenden Abläufe durch Manipulationen an der oder in der Honspindel vorgenommen werden können und keine Synchronisation mit einer externen Betätigungseinrichtung notwendig ist, wie sie bei einer Ausübung von Stellbewegungen am Honwerkzeug notwendig wären. Damit lässt sich eine vorteilhafte Synchronisierung und Integrierung des Ankopplungs- oder Abkopplungsvorgangs mit den weiteren, im Rahmen einer Honbearbeitung auftretenden Prozessschritten verwirklichen.According to a further aspect of the invention, a honing spindle has a shaft for transmitting forces and torques to a tool body of a honing tool. The shank is associated with a feed bar, which is provided for providing a processing force on a push rod of the honing tool. Furthermore, a tool holder is provided on the end of the shaft, which is designed for a releasable coupling of the honing tool, wherein the tool holder is associated with at least one adjusting device which is designed for fixing the tool body on the shaft. A particularly automatable fixing of the tool body of the honing tool on the shaft by means of an adjusting device associated with the shaft allows an advantageous substitution of honing tools, since all the coupling of the honing tool related operations by manipulation of the or in the honing spindle can be made and no synchronization with an external actuator is necessary, as would be necessary in an exercise of positioning movements on the honing tool. This can be an advantageous synchronization and integration of the coupling or decoupling process with the other, occurring in the context of honing process steps realize.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Werkzeugaufnahme zumindest eine, zumindest abschnittsweise kegelförmig gestaltete Ausnehmung zur Aufnahme eines korrespondierend geformten Kupplungsabschnitts des Honwerkzeugs aufweist. Damit kann eine hochpräzise und kostengünstig zu fertigende Kupplungsstruktur zwischen Honwerkzeug und Honspindel verwirklicht werden. Insbesondere kann die Werkzeugaufnahme der Honspindel für die Aufnahme eines als Hohlschaftkegel (HSK) geformten Kupplungsabschnitts des Honwerkzeugs gestaltet sein. Die kegelförmigen Kupplungsstrukturen an Honspindel und Honwerkzeug können weitgehend selbstzentrierend gestaltet sein, so dass bereits durch das Einstecken des Honwerkzeugs in die Ausnehmung der Honspindel eine Vorzentrierung mit weitgehend oder vollständig koaxialer Ausrichtung von Honspindelmittelachse und Honwerkzeugmittelachse und gegebenenfalls auch eine Vorfixierung des Honwerkzeugs verwirklicht werden kann.In a further embodiment of the invention it is provided that the tool holder has at least one, at least partially conical shaped recess for receiving a correspondingly shaped coupling portion of the honing tool. Thus, a high-precision and inexpensive to be produced coupling structure between honing tool and honing spindle can be realized. In particular, the tool holder of the honing spindle can be designed for receiving a coupling portion of the honing tool shaped as a hollow shaft cone (HSK). The cone-shaped coupling structures on honing spindle and honing tool can be designed largely self-centering, so that already by the insertion of the honing tool in the recess of the honing spindle pre-centering with largely or completely coaxial alignment of honing spindle center axis and honing tool center axis and optionally also a prefixing of the honing tool can be realized.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Stelleinrichtung für eine Auslenkung zumindest eines der Werkzeugaufnahme zugeordneten Riegelelements vorgesehen ist, das für eine Arretierung des Werkzeugkörpers am Schaft gestaltet ist. Mit Hilfe des Riegelelements kann eine formschlüssige Verbindung zwischen dem Honwerkzeug und der Honspindel geschaffen werden. Dazu wird das Riegelelement von der Stelleinrichtung aus einer Ruhestellung in eine Verriegelungsstellung ausgelenkt, in der es in das Honwerkzeug, insbesondere in eine hinterschnittene Ausnehmung des Honwerkzeugs, eingreift. Zu diesem Zweck kann die Stelleinrichtung mittels einer Translationsbewegung in Richtung des Honwerkzeugs die gewünschte Verriegelung herbeiführen, eine Aufhebung der Verrieglung zur Abkopplung des Honwerkzeugs erfolgt durch eine entgegengesetzte Stellbewegung der Stelleinrichtung.In a further embodiment of the invention it is provided that the adjusting device is provided for a deflection of at least one of the tool holder associated locking element, which is designed for a locking of the tool body on the shaft. With the help of the locking element, a positive connection between the honing tool and the honing spindle can be created. This is the locking element deflected by the adjusting device from a rest position into a locking position, in which it engages in the honing tool, in particular in an undercut recess of the honing tool. For this purpose, the adjusting device can bring about the desired locking by means of a translatory movement in the direction of the honing tool, a cancellation of the locking for decoupling of the honing tool is effected by an opposite adjusting movement of the adjusting device.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass sich das Riegelelement zumindest im Wesentlichen längs der Honspindelmittelachse erstreckt und jeweils endseitig angeordnete Vorsprünge zur formschlüssigen Verriegelung am Schaft und/oder am Honwerkzeug aufweist, wobei die Vorsprünge insbesondere paddelförmig gestaltet sind. Durch eine Erstreckung des Riegelelements längs der Honspindelmittelachse kann eine besonders schlanke Gestaltung der Honspindel erreicht werden. Die endseitigen Vorsprünge des Riegelelements erlauben die gewünschte formschlüssige Ankopplung des Werkzeugkörpers, wobei die dem Werkzeugkörper zugewandten Vorsprünge mit Schrägflächen versehen sein können, die bei einer durch die Stelleinrichtung hervorgerufenen Riegelbewegung, die im Wesentlichen in radialer, also orthogonaler Richtung zur Honspindelmittelachse stattfinden kann, eine axiale Bewegung des Honwerkzeugs in Richtung der Honspindel bewirken können. Somit wird die Zentrierungswirkung der kegelförmigen Kupplungsstrukturen an Honwerkzeug und Honspindel verstärkt und der Reibschluss der kegelförmigen Kupplungsstrukturen vergrößert.In a further embodiment of the invention, it is provided that the locking element extends at least substantially along the Honspindelmittelachse and each end arranged projections for positive locking on the shaft and / or the honing tool, wherein the projections are designed in particular paddle-shaped. By extending the locking element along the Honspindelmittelachse a particularly slim design of the honing spindle can be achieved. The end-side projections of the locking element allow the desired form-fitting coupling of the tool body, wherein the tool body facing projections may be provided with inclined surfaces, which in an induced by the actuator latch movement, which may take place substantially in the radial, ie orthogonal direction to the Honspindelmittelachse, an axial Can cause movement of the honing tool in the direction of the honing spindle. Thus, the centering effect of the cone-shaped coupling structures is reinforced on honing tool and honing spindle and increases the frictional engagement of the conical coupling structures.
Gemäß einem weiteren Aspekt der Erfindung weist ein Honwerkzeug zur Durchführung eines Honvorgangs an einem Werkstück einen Werkzeugkörper und zumindest einem relativ zum Werkzeugkörper beweglich angebrachten Schneidstoffkörper sowie eine Druckstange auf, die zur Ansteuerung der Honleiste längs einer Mittelachse des Werkzeugkörpers bewegbar ist und die mit einer Kupplungseinrichtung für eine lösbare, kraftübertragende Verbindung mit einer Zustellstange einer Honspindel versehen ist. Der Werkzeugkörper weist an seinem dem Schneidstoffkörper abgewandten Endbereich einen zumindest abschnittsweise kegelstumpfförmigen Kupplungsabschnitt zur Ankopplung an eine korrespondierend geformte Werkzeugaufnahme der Honspindel auf. Ein derartiges Honwerkzeug ist im Vergleich zu herkömmlichen Honwerkzeugen in gleicher oder verbesserter Präzision kostengünstiger herzustellen, da lediglich starre Kupplungsstrukturen für den Werkzeugkörper und die Druckstange vorgesehen werden müssen. Zudem ist ein derartiges Honwerkzeug automatisiert auswechselbar, was die Gestaltung eines Honverfahrens maßgeblich verbessert, da ein schneller und sicherer Honwerkzeugwechsel vorgenommen werden kann, ohne auf einen Bediener angewiesen zu sein. Dies ist insbesondere in der Massenfertigung von Bedeutung, da in der Honmaschine ein Magazin mit mehreren Honwerkzeugen vorgesehen werden kann, auf die beispielsweise bei Verschleiß des in Benutzung befindlichen Honwerkzeugs ohne Weiteres zugegriffen werden kann.According to a further aspect of the invention, a honing tool for performing a honing process on a workpiece has a tool body and at least one cutting material body movably mounted relative to the tool body and a push rod which for controlling the honing stone along a central axis of the tool body is movable and which is provided with a coupling device for a releasable, force-transmitting connection with a feed rod of a honing spindle. The tool body has at its end region facing away from the cutting material body an at least partially frusto-conical coupling section for coupling to a correspondingly shaped tool holder of the honing spindle. Such a honing tool is cheaper to produce compared to conventional honing tools with the same or improved precision, since only rigid coupling structures for the tool body and the push rod must be provided. In addition, such a honing tool is automatically interchangeable, which significantly improves the design of a honing process, since a faster and safer Honwerkzeugwechsel can be made without relying on an operator. This is particularly important in mass production, since in the honing machine, a magazine with several honing tools can be provided, which can be easily accessed, for example, in wear of the honing tool in use.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der abschnittsweise kegelförmige Kupplungsabschnitt als Hohlschaftkegel ausgeführt ist. Mit einem Hohlschaftkegel wird eine hochpräzise Werkzeugschnittstelle zur Verfügung gestellt, die beispielsweise aus dem Bereich der Fräswerkzeuge grundsätzlich bekannt ist und daher mit etablierten Fertigungsprozessen kostengünstig hergestellt werden kann. In die Gestaltung des Hohlschaftkegels ist ein erheblicher Erfahrungsschatz eingeflossen, der zumindest teilweise für die spezifischen Belange des Honverfahrens übernommen werden kann.In a further embodiment of the invention it is provided that the sectionally conical coupling portion is designed as a hollow shaft taper. With a hollow shaft cone, a high-precision tool interface is made available which, for example, is basically known from the field of milling tools and can therefore be manufactured cost-effectively with established manufacturing processes. In the design of the hollow shaft cone a considerable wealth of experience has been incorporated, which can be at least partially adopted for the specific needs of the honing process.

Die Kupplungshaken 8 erstrecken sich in der Ruhestellung gemäß der
Die Zustellstange 5 ist zweiteilig aufgebaut und hat einen antriebsseitigen oberen Teil und einen mit dem oberen Teil verschraubten unteren Teil, der an seinem Endbereich in der Werkzeugaufnahme 4 eine zweistufige zylindrische Verdickung aufweist, wobei eine in der Verdickung vorgesehene Bohrung eine Druckstangenaufnahme 10 bildet. An die Druckstangenaufnahme 10 schließt sich eine als Fluidkanal ausgeführte Fluidbohrung 35 an, die sich längs der gesamten Länge der Zustellstange 5 erstreckt und für eine Versorgung der Druckstange 19 mit einem Fluid, insbesondere mit einem Honöl, vorgesehen ist. An einer Stirnfläche der Druckstangenaufnahme 10 ist eine umlaufende Dichtnut 36 zur Aufnahme einer als O-Ring ausgeführten Kupplungsdichtung 12 vorgesehen. Die Verdickung wird von einer Kupplungshülse 14 umschlossen, die relativbeweglich zur Zustellstange 5 angeordnet ist, wobei durch die zweistufige Gestaltung der Verdickung eine ringförmige Stirnfläche zur Verfügung steht, die als Auflagefläche für eine Kupplungsfeder 11 vorgesehen ist. Die Kupplungsfeder 11 ist in der dargestellten Ruhestellung der Honspindel 1 durch die Einwirkung des Steuerrohrs 6 vorgespannt und stützt sich an einer Innenfläche der Kupplungshülse 14 ab. In einem Endbereich der Druckstangenaufnahme ist eine Querbohrung orthogonal zur Honspindelmittelachse 23 angebracht, in die jeweils ein als Kupplungskugel 13 ausgeführter Kupplungskörper eingesetzt ist. Um ein Herausfallen der Kupplungskugeln 13 zu verhindern, ist die Querbohrung jeweils an einer Innenfläche der Druckstangenaufnahme 10 mit einer den Bohrungsdurchmesser reduzierenden Einprägung versehen. In radialer Richtung nach außen werden die Kupplungskugeln 13 durch die Kupplungshülse 14 in ihrer Bewegung begrenzt und liegen auf nach radial nach innen gewandten Steuerflächen 15 der Kupplungshülse 14 auf, die jeweils einen spitzen Winkel mit der Honspindelmittelachse 23 einschließen. Damit kann bei einer translatorischen Relativbewegung der Kupplungshülse 14 gegenüber der Zustellstange 5 eine translatorische, gegensinnige Bewegung der Kupplungskugeln 13 in Querrichtung zur Honspindelmittelachse 23 hervorgerufen werden.The
