Description

Die Erfindung betrifft eine Hochgeschwindigkeits-Honmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a high-speed honing machine according to the preamble of patent claim 1.

Auf Honmaschinen werden vor allem Bohrungen durch eine Feinbearbeitung der Innenoberfläche hinsichtlich ihrer Maß- und Formgenauigkeit durch eine Feinbearbeitung der Innenoberfläche verbessert.On Honmaschinen especially bores are improved by a fine machining of the inner surface with respect to their dimensional and dimensional accuracy by a fine machining of the inner surface.

Bei bekannten Honmaschinen wird das Honwerkzeug rotierend angetrieben, in die zu bearbeitende Bohrung eingeführt und oszillierend in Längsrichtung der Bohrung hin und her bewegt. Dadurch entsteht an der Innenoberfläche der Bohrung ein Kreuzschliff oder ein Sinusschliff. Die Drehzahl und die Oszillationsgeschwindigkeit müssen dabei genau aufeinander abgestimmt werden. Da das Honwerkzeug in einer Werkzeugspindel gespannt ist, muss diese einschließlich des Rotationsantriebs der Spindel ebenfalls oszillierend angetrieben werden. Die dabei zu bewegenden Massen sind relativ groß, sodass einer Steigerung der Oszillationsgeschwindigkeit und damit auch der Drehzahl des Honwerkzeugs Grenzen gesetzt sind.In known honing machines, the honing tool is rotationally driven, introduced into the bore to be machined and reciprocated in the longitudinal direction of the bore. This results in a cross-cut or a sine cut on the inner surface of the hole. The speed and the oscillation speed must be exactly matched. Since the honing tool is clamped in a tool spindle, it must also be driven in an oscillating manner, including the rotational drive of the spindle. The masses to be moved are relatively large, so that an increase in the oscillation speed and thus the speed of the honing tool are limited.

In der DE 10 2007 045 045 A1 ist bereits generell vorgeschlagen worden, das Werkstück oszillierend anzutreiben.In the DE 10 2007 045 045 A1 It has already been proposed in general to drive the workpiece in an oscillating manner.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Honmaschine vorzuschlagen, mit der noch höhere Bearbeitungsgeschwindigkeiten als mit der bekannten Honmaschine möglich sind.The present invention has for its object to provide a honing machine, with even higher processing speeds than with the known honing machine are possible.

Die Aufgabe wird gelöst mit einer Honmaschine mit den Merkmalen des Anspruchs 1.The object is achieved with a honing machine having the features of claim 1.

Bei der erfindungsgemäßen Honmaschine wird nicht die Werkzeugspindel mit dem Honwerkzeug oszillierend angetrieben, sondern der Werkstückträger mit dem Werkzeug, die in aller Regel eine deutlich geringere Masse aufweisen als die Werkzeugspindel mit ihrer Antriebseinrichtung und dem Honwerkzeug. Es lassen sich somit für den Werkstückträger mit dem Werkzeug deutlich höhere Oszillationsgeschwindigkeiten erreichen als für das Honwerkzeug bei Honmaschinen mit feststehendem Werkzeugträger. Aufgrund der höheren Oszillationsgeschwindigkeiten kann auch die Drehzahl des Honwerkzeugs gegenüber den Maschinen nach dem Stand der Technik erhöht werden, sodass sich insgesamt deutlich geringer Bearbeitungszeiten für die Werkstücke ergeben. Die Verwendung eines Linearmotors zum Antrieb des Werkstückträgers hat dabei den Vorteil, dass auf Getriebe verzichtet werden kann und hohe Beschleunigungen erreichbar sind.In the honing machine according to the invention, the tool spindle is not driven in an oscillating manner with the honing tool, but the workpiece carrier with the tool, which as a rule has a significantly lower mass than the tool spindle with its drive device and the honing tool. Thus, significantly higher oscillation speeds can be achieved for the workpiece carrier with the tool than for the honing tool in honing machines with a stationary tool carrier. Due to the higher oscillation speeds, the speed of the honing tool can be increased compared to the state-of-the-art machines, resulting in significantly shorter machining times for the workpieces. The use of a linear motor for driving the workpiece carrier has the advantage that can be dispensed with transmission and high accelerations are achievable.

Die erfindungsgemäße Honmaschine hat weiter den Vorteil, dass durch die höheren möglichen Drehzahlen mit einem relativ groben Reibbelag des Honwerkzeugs eine relativ feine Bearbeitung der Bohrungsoberfläche möglich ist, sodass zur Bearbeitung der Bohrung weniger unterschiedliche Honwerkzeuge eingesetzt werden müssen. Neben der Ersparnis an Werkzeugkosten sind dadurch weitere Verkürzungen der Bearbeitungszeit des Werkstücks erreichbar.The honing machine according to the invention has the further advantage that a relatively fine machining of the bore surface is possible by the higher possible speeds with a relatively coarse friction lining of the honing tool, so that less different honing tools must be used for machining the bore. In addition to the savings Tool costs are thereby achievable further shortening of the machining time of the workpiece.

Der Werkstückträger ist an einem mit dem Läufer des Linearmotors verbundenen Schlitten angeordnet. Der Schlitten lässt sich relativ reibungsarm beispielsweise an einer Schienenanordnung an der Maschine führen, was die erreichbaren Geschwindigkeiten zusätzlich erhöht. Schlitten und Läufer des Linearmotors können dabei auch einteilig ausgebildet sein, d. h. der Schlitten kann den Läufer des Linearmotors bilden. Die zu bewegenden Massen können dadurch weiter reduziert werden.The workpiece carrier is arranged on a slide connected to the rotor of the linear motor. The carriage can be relatively low friction, for example, lead to a rail assembly on the machine, which additionally increases the achievable speeds. Carriage and rotor of the linear motor can also be integrally formed, d. H. the carriage can form the rotor of the linear motor. The masses to be moved can thereby be further reduced.

Die Werkzeugspindel ist relativ zum Werkstückträger verstellbar angeordnet. Auf diese Weise lässt sich der Freiraum zwischen der Werkzeugspindel und dem Werkstückträger verkürzen oder verlängern, sodass ohne den Einsatz von Werkzeugverlängerungen unterschiedlich hoch bauende Werkstücke mit der Honmaschine bearbeitet werden können. Die Umstellung der Maschine auf unterschiedliche Werkstücke ist ebenfalls ausgesprochen einfach.The tool spindle is arranged relative to the workpiece carrier adjustable. In this way, the space between the tool spindle and the workpiece carrier can be shortened or lengthened, so that workpieces of different heights can be processed with the honing machine without the use of tool extensions. The conversion of the machine to different workpieces is also extremely simple.

Eine weitere Steigerung der Leistungsfähigkeit der Maschine ist dadurch möglich, dass auch die Werkzeugspindel oszillierend antreibbar ausgestaltet werden kann. Die Oszillationsbewegungen des Werkstückträgers und der Werkzeugspindel lassen sich dann derart überlagern, dass nochmals eine Steigerung der Drehzahl des Honwerkzeugs möglich ist, um auf der Innenseite der bearbeiteten Bohrung das gewünschte Schliffbild zu erzeugen. Die Werkzeugspindel kann hierzu an einem mittels eines Linearantriebs antreibbaren Schlitten angeordnet sein. Als Linearantrieb kommen neben einem Linearmotor prinzipiell auch Hydraulik- oder Pneumatikzylinder oder Gewindetriebe infrage.A further increase in the performance of the machine is possible because the tool spindle can also be made to oscillate drivable. The oscillatory movements of the workpiece carrier and the tool spindle can then be superimposed in such a way that once again an increase in the speed of the honing tool is possible in order to be able to move on Inside the machined hole to create the desired microsection. For this purpose, the tool spindle can be arranged on a carriage which can be driven by means of a linear drive. As a linear drive in addition to a linear motor in principle also hydraulic or pneumatic cylinders or screw drives in question.

Zweckmäßigerweise kann an der Honmaschine außerdem eine Steuerungseinrichtung vorgesehen sein, mit der die vom Werkstückträger ausführbare Oszillationsbewegung und die Drehzahl der Werkzeugspindel aufeinander abstimmbar sind, sodass sich der gewünschte Schliff am Werkstück bildet und Bedienungsfehler praktisch ausgeschlossen sind. Außerdem können auch die oszillierenden Bewegungen des Werkstückträgers und der Werkzeugspindel mittels der Steuerungseinrichtung aufeinander abgestimmt bzw. synchronisiert werden. Die Steuerungseinrichtung erleichtert zudem die Einstellung der Maschine auf neue Honaufgaben.Expediently, a control device can also be provided on the honing machine with which the oscillation movement executable by the workpiece carrier and the rotational speed of the tool spindle can be matched to one another, so that the desired grinding is formed on the workpiece and operating errors are virtually ruled out. In addition, the oscillating movements of the workpiece carrier and the tool spindle can be matched or synchronized by means of the control device. The control device also facilitates setting the machine to new honing tasks.

Bei einer weiteren vorteilhaften Ausgestaltung der Honmaschine kann die Werkzeugspindel ein Hydrodehn-Spannfutter mit innen liegender Kühlmittelzufuhr aufweisen. Hydrodehn-Spannfutter sorgen für eine hydraulische Schwingungsdämpfung des gespannten Werkzeugs. Aufgrund der höheren Rundlaufgenauigkeiten der Werkzeuge können dadurch höhere Standzeiten für diese erreicht werden. Die innen liegende Kühlmittelzufuhr vermeidet frei liegende Schlauchleitungen für das Kühlmittel an der Maschine.In a further advantageous embodiment of the honing machine, the tool spindle can have a hydraulic chuck with an internal coolant supply. Hydraulic chucks provide hydraulic vibration damping of the tensioned tool. Due to the higher concentricity of the tools higher service life for these can be achieved. The internal coolant supply prevents exposed hose lines for the coolant on the machine.

Außerdem kann in die Werkzeugspindel ein Honwerkzeug mit einem zylindrischen Reibbelag, der einen Längsschlitz aufweist und radial aufweitbar ist, einsetzbar sein. Standard-Honwerkzeuge, die natürlich ebenfalls eingesetzt werden können, weisen Leisten mit Reibbelägen auf, wobei sich diese Leisten jedoch bei der Bearbeitung eines Werkstücks nach außen biegen und dadurch zu einer Unwucht des rotierend angetriebenen Werkzeugs führen können. Das Werkzeug gerät dadurch in Schwingungen, die sowohl zu einer Zerstörung des Werkstücks als auch des Werkzeugs führen können. Bei Honwerkzeugen mit zylindrischem Reibbelag werden diese Probleme vermieden.In addition, in the tool spindle, a honing tool with a cylindrical friction lining, which has a longitudinal slot and is radially expandable, can be used. Standard honing tools, which of course can also be used, have strips with friction linings, but these strips are in the machining of a workpiece to the outside bend and thereby can lead to an imbalance of the rotary driven tool. As a result, the tool vibrates, which can lead to destruction of both the workpiece and the tool. When honing tools with cylindrical friction lining these problems are avoided.

Die Honmaschine kann zusätzlich mit einer Mess- und/oder Entgratstation ausgerüstet sein. Diese Bearbeitungsschritte des Werkstücks können somit ebenfalls innerhalb der Honmaschine durchgeführt werden.The honing machine can additionally be equipped with a measuring and / or deburring station. These processing steps of the workpiece can thus also be carried out within the honing machine.

Da der Werkstückträger bei der erfindungsgemäßen Honmaschine nicht feststehend angeordnet ist, ist es außerdem von Vorteil, wenn die Maschine eine Robotereinrichtung zum Be- und Entladen des Werkstückträgers und/oder der Messstation und/oder der Entgratstation aufweist. Die Robotereinrichtung kann beispielsweise eine Sechs-Achs-Robotereinrichtung sein, mit der ein beliebig geformtes Werkstück erfasst und auf beliebigem Wege durch den Bearbeitungsraum bewegt und an der gewünschten Stelle abgesetzt werden kann.Since the workpiece carrier is not fixedly arranged in the honing machine according to the invention, it is also advantageous if the machine has a robot device for loading and unloading the workpiece carrier and / or the measuring station and / or the deburring station. The robot device can be, for example, a six-axis robot device with which an arbitrarily shaped workpiece can be detected and moved through the processing space in any desired way and deposited at the desired location.

Sollen große Stückzahlen von Werkstücken bearbeitet werden, so können dazu mehrere erfindungsgemäße Honmaschinen eingesetzt werden. Sie lassen sich dabei unmittelbar nebeneinander anordnen. Insbesondere für diesen Fall ist es von Vorteil, wenn die Maschine ein Gehäuse mit verschließbaren Öffnungen aufweist, durch die der Bearbeitungsraum des Werkstücks durch Robotereinrichtungen benachbart angeordneter Honmaschinen oder anderer Bearbeitungsmaschinen oder Transporteinrichtungen zugänglich ist. So kann beispielsweise mit der ersten Honmaschine eine Grobbearbeitung der Bohrungen, mit einer zweiten Maschine eine feinere Bearbeitung und mit einer dritten Maschine die Endbearbeitung der Bohrungen vorgenommen werden. Die Werkstücke lassen sich dabei von den Robotereinrichtungen der Maschinen von einer Maschine in die nächste bewegen, oder es kann ein neues Werkstück geladen werden, während gerade bearbeitete Werkstücke vermessen und/oder entgratet werden.If large numbers of workpieces are to be processed, several honing machines according to the invention can be used for this purpose. They can be arranged directly next to each other. In particular, in this case, it is advantageous if the machine has a housing with closable openings, through which the processing space of the workpiece by robot means adjacent arranged honing machines or other processing machines or transport facilities is accessible. Thus, for example, with the first honing machine, a rough machining of the holes, with a second machine finer machining and with a third machine, the finishing of the holes are made. The workpieces can be from move the robotic devices of the machines from one machine to the next, or a new workpiece can be loaded while measuring and deburring just machined workpieces.

Nachfolgend wird eine bevorzugte Ausführungsform einer erfindungsgemäßen Honmaschine anhand der Zeichnung näher beschrieben.Hereinafter, a preferred embodiment of a honing machine according to the invention will be described in more detail with reference to the drawing.

Die Honmaschine 10 gemäß Fig. 1 weist ein Untergestell 11 auf, auf dem ein Ständer 12 angeordnet ist, der eine Werkzeugspindeleinrichtung 13 sowie einen Schlitten 14, an dem ein Werkstückträger 15 befestigt ist, angeordnet sind. Der Schlitten 14 ist mittels eines hier nicht näher dargestellten Linearmotors in vertikaler Richtung oszillierend antreibbar. Dabei kann der Schlitten 14 vorzugsweise gleichzeitig der Läufer des Linearmotors sein. Die Werkzeugspindel 13, an deren Spannfutter 16 ein Honwerkzeug befestigbar ist, ist rotierend antreibbar und kann am Ständer 12 bezüglich des Werkstückträgers 15 verstellt werden. Es ist außerdem möglich, auch die Spindel 13 in vertikaler Richtung oszillierend anzutreiben.The honing machine 10 according to Fig. 1 has a base 11, on which a stand 12 is arranged, which a tool spindle device 13 and a carriage 14, on which a workpiece carrier 15 is attached, are arranged. The carriage 14 is driven to oscillate in the vertical direction by means of a linear motor, not shown here. In this case, the carriage 14 may preferably be simultaneously the rotor of the linear motor. The tool spindle 13, on the chuck 16 a honing tool can be fastened, is rotatably driven and can be adjusted on the stand 12 with respect to the workpiece carrier 15. It is also possible to drive the spindle 13 in the vertical direction oscillating.

Weiter sind auf dem Untergestell eine Robotereinrichtung 17, hier ein Sechs-Achs-Roboter sowie eine Messeinrichtung 18 angeordnet. Mithilfe der Robotereinrichtung 17 kann ein hier nicht näher dargestelltes Werkstück auf dem Werkstückträger 15 platziert, von diesem entnommen und der Messstation 18 zugeführt werden. Von der Messstation 18 kann das Werkstück beispielsweise an eine benachbart angeordnete Honmaschine oder eine andere Bearbeitungsmaschine übergeben werden.Next, a robot device 17, here a six-axis robot and a measuring device 18 are arranged on the base. By means of the robot device 17, a workpiece (not shown here in detail) can be placed on the workpiece carrier 15, removed therefrom and fed to the measuring station 18. From the measuring station 18, the workpiece can be transferred, for example, to an adjacently arranged honing machine or another processing machine.

Die Honmaschine 10 weist außerdem einen Schaltschrank 19 auf, in dem neben der Stromversorgung auch die Steuerungseinrichtung der Maschine angeordnet ist. Weiter ist ein Kühlaggregat 20 vorgesehen, mit dessen Hilfe der Werkzeugspindel 13 ein Kühlmittel zugeführt werden kann.The honing machine 10 also has a control cabinet 19, in which in addition to the power supply and the control device of the machine is arranged. Next, a cooling unit 20 is provided, with the aid of the tool spindle 13, a coolant can be supplied.

Wie Fig. 2 zeigt, weist die Honmaschine 10 außerdem ein Gehäuse 21 auf, das den Bearbeitungsraum 22 für das Werkstück, den Bereich zwischen dem Ständer 12 und dem Schaltschrank 19 (Fig. 1) sowie den Bereich des Ständers 12 und des Kühlaggregats 20 nach außen hin abschließt. Im Bereich des Arbeitsraums weist das Gehäuse 21 nach vorne eine Sichtscheibe 23 und seitlich durch hier nicht dargestellte Gehäuseteile verschließbare Öffnungen 24 auf. Werden mehrere Hohnmaschinen 10 nebeneinander gestellt, so kann die Robotereinrichtung 17 durch die Öffnungen 24 Werkstücke von dem Bearbeitungsraum 22 einer Maschine zum Bearbeitungsraum 22 der benachbarten Maschine oder umgekehrt transportieren.As Fig. 2 shows, the honing machine 10 also has a housing 21, the processing space 22 for the workpiece, the area between the stator 12 and the control cabinet 19 (FIGS. Fig. 1 ) and the region of the stator 12 and the cooling unit 20 to the outside closes. In the area of the working space, the housing 21 has a viewing window 23 at the front and openings 24 which can be closed laterally by housing parts (not shown here). If several machines Hohnmaschinen 10 placed side by side, so the robot device 17 can transport through the openings 24 workpieces from the processing space 22 of a machine to the processing space 22 of the adjacent machine or vice versa.

Die Gehäuseteile 25, 26 im Bereich des Zwischenraums zwischen dem Schaltschrank 19 einerseits und dem Ständer 12 sowie dem Kühlaggregat 20 andererseits sind als Türen ausgebildet. Durch sie sind sowohl der Schaltschrank 19 als auch die Antriebe für die Spindel 13 und den Werkzeugschlitten 14 für Reparaturarbeiten zugänglich. Werden mehrere Honmaschinen nebeneinander angeordnet, so können die Türen 25, 26 zwischen den einzelnen Maschinen 10 entnommen werden, wodurch ein durchgehender Revisionsbereich für sämtliche Maschinen entsteht.The housing parts 25, 26 in the region of the gap between the cabinet 19 on the one hand and the stand 12 and the cooling unit 20 on the other hand are formed as doors. Through them, both the control cabinet 19 and the drives for the spindle 13 and the tool carriage 14 are accessible for repair work. Become several Honing machines arranged side by side, so the doors 25, 26 can be removed between the individual machines 10, creating a continuous inspection area for all machines.
