Description

Die vorliegende Erfindung betrifft eine Abrichtrollenmontageeinrichtung zur Montage einer Abrichtrolle auf einer Abrichterwelle einer Schleifscheibenabrichteinheit.The present invention relates to a dressing roll mounting device for mounting a dressing roll on a dresser shaft of a grinding wheel dressing unit.

Schleifscheibenabrichteinheiten dienen zum Profilieren von Schleifscheiben und sind häufig direkt in Schleifmaschinen integriert. Sie verfügen über eine eigene Antriebseinheit zum Antreiben einer Abrichterwelle, auf der die Abrichtrolle montiert ist. Durch Einsenken der sich drehenden Abrichtrolle in die sich drehende Schleifscheibe erfolgt eine Abrichtung des Schleifscheibenprofils. Das Abrichten kann intermittierend oder kontinuierlich während der Bearbeitung eines Werkstückes durch die Schleifscheibe erfolgen, wobei ein kontinuierliches Abrichten dahingehend von Vorteil ist, dass ein Zusetzen der Schleifscheibe mit Metallpartikeln verhindert und damit eine ständig scharfe Schleifscheibe garantiert wird. Die Schleifscheibendurchmessenverminderung, die durch den Schleifscheibenverschleiß bei der Bearbeitung und durch den Abrichtprozess entsteht, wird mit Hilfe einer entsprechenden Zustellung der Abrichtrolle kompensiert.Grinding wheel dressing units are used for profiling grinding wheels and are often integrated directly into grinding machines. They have their own drive unit for driving a dresser shaft on which the dressing roller is mounted. By sinking the rotating dressing roller into the rotating grinding wheel, a dressing of the grinding wheel profile takes place. The dressing can be done intermittently or continuously during the processing of a workpiece by the grinding wheel, wherein continuous dressing is advantageous in that clogging of the grinding wheel with metal particles is prevented and thus a constantly sharp grinding wheel is guaranteed. The grinding wheel diameter reduction caused by the grinding wheel wear during machining and by the dressing process is compensated by means of a corresponding feed of the dressing roller.

Beim Tiefschleifprozess von Turbinenschaufeln müssen besonders enge Toleranzen gefertigt werden. Zur Profilierung der eingesetzten Schleifscheiben werden in der Regel galvanisch gebundene Diamantabrichtrollen eingesetzt. Diese werden mittels Übergangspassung auf Abrichterwellen gefügt und so in der Schleifmaschine montiert bzw. angetrieben. Dabei werden sehr hohe Toleranzanforderungen zur Erzielung eines ordnungsgemäßen Rund- und Planlaufs gestellt. Die Montage der Abrichtrollen an den Abrichterwellen erfolgt normalerweise entweder direkt im Bearbeitungsraum der Schleifmaschine oder in einem Werkstattumfeld, wobei im letzteren Fall der Ausbau der Abrichterwelle samt Abrichtrolle und der Transport in die Werkstatt erforderlich sind. Bei der Montage sowie bei der Demontage der Abrichtrolle an bzw. von der Abrichterwelle sind derzeit zusätzliche Abrichtrollenmontageeinrichtungen erforderlich, wie beispielsweise Wärmeschränke, Kälteschränke, Eindruckpressen oder dergleichen. Trotzdem kann ein Verkanten von Abrichtrolle und Abrichterwelle während der Montage bzw. Demontage häufig nicht verhindert werden, weshalb die hoch präzise gefertigten Wellen und/oder Bohrungen der zu fügenden Bauteile beschädigt werden.In the deep grinding process of turbine blades, particularly tight tolerances must be produced. For profiling the grinding wheels used usually galvanically bonded diamond dressing rolls are used. These are joined by means of transition fit on dresser shafts and so mounted or driven in the grinding machine. In this case, very high tolerance requirements for achieving a proper round and plan run are made. The installation of the dressing rolls on the dresser shafts is usually carried out either directly in the processing room of the grinding machine or in a workshop environment, in the latter case, the removal of the dresser shaft including dressing roller and transport to the workshop are required. During assembly as well as during disassembly of the dressing roller to or from the dresser shaft Additional dressing roll fixtures are currently required, such as thermal cabinets, refrigerators, impression presses, or the like. Nevertheless, tilting of the dressing roller and the dresser shaft during assembly or disassembly can often not be prevented, which is why the highly precisely manufactured shafts and / or bores of the components to be joined are damaged.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Abrichtrollenmontageeinrichtung der eingangs genannten Art zu schaffen, bei der eine Beschädigung der hoch präzise gefertigten Welle und/oder Bohrung der zu fügenden Bauteile verhindert wird. Zudem soll eine problemlose Abrichtrollenmontage und gegebenenfalls auch Demontage von Abrichtrollen im Bearbeitungsraum von Schleifmaschinen ermöglicht werden. Noch eine weitere Aufgabe besteht darin, eine Abrichtrollenmontageeinrichtung zu schaffen, bei der auf aufwendige Montagehilfsmittel, insbesondere auf Wärmeschränke und Kälteschränke verzichtet werden kann.It is an object of the present invention to provide a Abrichtrollenmontageeinrichtung of the aforementioned type, in which damage to the highly precisely manufactured shaft and / or bore of the components to be joined is prevented. In addition, a trouble-free Abrichtrollenmontage and possibly also disassembly of dressing rolls in the processing room of grinding machines to be made possible. Yet another object is to provide a Abrichtrollenmontageeinrichtung in which can be dispensed with expensive installation tools, in particular on heat cabinets and refrigerators.

Diese Aufgabe wird gemäß der vorliegenden Erfindung dadurch gelöst, dass die Abrichtrollenmontageeinrichtung eine an einem freien Ende der Abrichterwelle positionierbare Montagehülse aufweist, deren Außenfläche mit einem konischen Montagebereich versehen ist, der als Zentrier- und Aufschiebehilfe bei der Montage der Abrichtrolle auf der Abrichterwelle dient, wobei ein maximaler Außendurchmesser des konischen Montagebereiches kleiner als ein Abrichtrollenaufnahmedurchmesser der Abrichterwelle ist oder diesem entspricht.This object is achieved according to the present invention in that the Abrichtrollenmontageeinrichtung has a positionable at a free end of the dresser shaft mounting sleeve whose outer surface is provided with a conical mounting portion, which serves as centering and Aufschiebehilfe during assembly of the dressing roller on the dresser shaft a maximum outer diameter of the tapered mounting portion is smaller than or equal to a dressing roll receiving diameter of the dresser shaft.

Entsprechend wird die Abrichtrollenbohrung nicht direkt auf das Ende der Abrichterwelle aufgeschoben, sondern zunächst auf den konischen Montagebereich der Abrichtrollenmontageeinrichtung, dessen Durchmesser kleiner als oder gleich dem Abrichtrollenaufnahmedurchmesser der Abrichterwelle ist. Auf diese Weise kann ein Verkanten der Abrichtrolle der Abrichterwelle beim Aufsetzen der Abrichtrolle auf die Abrichterwelle und entsprechend eine Beschädigung der hoch präzise gefertigten Bohrung bzw. Welle sicher verhindert werden. Entsprechend kann eine Montage bzw. Demontage der Abrichterwelle auch verhältnismäßig problemlos im Bearbeitungsraum einer Schleifmaschine erfolgen. Ferner kann die automatische Zentrierung der Abrichtrollenbohrung zur Abrichterwelle beim Aufschieben auf den konischen Montagebereich der erfindungsgemäßen Abrichtrollenmontageeinrichtung und die damit einhergehende optimierte Ausrichtung der zu fügenden Bauteile den Einsatz von Wärme- und/oder Kälteschränken überflüssig machen. Entsprechend können Montage-/Demontagezeiten sowie Kosten verringert werden.Accordingly, the dressing roll bore is not slid directly onto the end of the dresser shaft, but first onto the conical mounting region of the dressing roll assembly, the diameter of which is less than or equal to the dressing roll take-up diameter of the dresser shaft. In this way, a tilting of the dressing roller of the dresser shaft when placing the dressing roller on the dresser shaft and, accordingly, damage of the highly precisely manufactured Hole or shaft can be safely prevented. Accordingly, a mounting or dismounting of the dresser shaft can also take place relatively easily in the processing space of a grinding machine. Furthermore, the automatic centering of the dressing roll bore to the dresser shaft when pushed onto the conical mounting region of the dressing roll mounting device according to the invention and the associated optimized alignment of the components to be joined make the use of heat and / or cold cabinets superfluous. Accordingly, assembly / disassembly times and costs can be reduced.

Die Außenfläche der Montagehülse kann mit einem konischen Demontagebereich versehen sein, der als Abstreifhilfe bei der Demontage der Abrichtrolle von der Abrichterwelle dient. Auf diese Weise wird auch die Demontage wesentlich erleichtert.The outer surface of the mounting sleeve may be provided with a conical disassembly area, which serves as Abstreifhilfe during disassembly of the dressing roller from the dresser shaft. In this way, the disassembly is much easier.

Der Montagebereich und der Demontagebereich sind vorteilhaft derart angeordnet, dass sie ineinander übergehen. Der Demontagebereich ist im bestimmungsgemäßen Zustand der Abrichtrollenmontageeinrichtung bevorzugt der Abrichterwelle zugewandt, während der Montagebereich der Abrichterwelle abgewandt ist.The mounting area and the disassembly area are advantageously arranged such that they merge into one another. The dismantling area is preferably in the intended condition of Abrichtrollenmontageeinrichtung facing the dresser shaft, while the mounting region of the dresser shaft is facing away.

Der Montagebereich und, falls vorhanden, der Demontagebereich, erstrecken sich bevorzugt über die gesamte Länge der Montagehülse, so dass diese optimal genutzt wird.The mounting area and, if present, the disassembly area, preferably extend over the entire length of the mounting sleeve, so that it is used optimally.

Die Montagehülse ist bevorzugt derart ausgebildet, dass sie an einem Spindelzapfen der Abrichterwelle befestigbar ist. In diesem Fall lässt sich die Abrichtrollenmontageeinrichtung besonders einfach an der Abrichterwelle montieren.The mounting sleeve is preferably designed such that it can be fastened to a spindle journal of the dresser shaft. In this case, the Abrichtrollenmontageeinrichtung particularly easy to mount on the dresser shaft.

Die Montagehülse ist bevorzugt aus einem Material mit großer Härte hergestellt, wie beispielsweise aus einer vorteilhaft gehärteten Chrom-Nickel-Legierung.The mounting sleeve is preferably made of a material having a high hardness, such as, for example, an advantageously hardened chromium-nickel alloy.

Figur 1 zeigt eine Abrichtrollenmontageeinrichtung 10 während der Montage einer Abrichtrolle 12 auf einer Abrichterwelle 14 einer nicht näher dargestellten Schleifscheibenabrichteinheit. Die Abrichtrollenmontageeinrichtung 10 besteht aus einer länglichen Montagehülse 16, die zentrisch mit einer Durchgangsbohrung 18 versehen ist. In dem in Figur 1 dargestellten Zustand ist diese Montagehülse 16 am Spindelzapfen 20 der Abrichterwelle 14 befestigt, der während des Normalbetriebs der Schleifmaschinenabrichteinheit in einer entsprechenden Lagerung aufgenommen ist. Zur Erleichterung der Montage der Abrichtrolle 12 auf dem Abrichtrollenaufnahmedurchmesser D der Abrichterwelle 14 ist die Außenfläche der Montagehülse 16 entlang ihrer gesamten Länge L mit einem konischen Montagebereich 22 versehen, dessen Außendurchmesser sich ausgehend von einem maximalen Außendurchmesser dmax in Richtung des freien Endes 23 des Spindelzapfens 20 bis hin zu einem minimalen Außendurchmesser dmin verjüngt, wobei dmax ≤ dem Abrichtrollenaufnahmedurchmesser D ist. Entsprechend wird die Abrichtrolle 12 beim Aufziehen auf die Montagehülse 16 durch das Zusammenwirken der Außenfläche der Montagehülse 16 und der Wandung der Abrichtrollenbohrung 25 automatisch in Bezug auf den Abrichtrollenaufnahmendurchmesser D der Abrichterwelle 14 zentriert, auf dem die Abrichtrolle 12 letztendlich befestigt werden soll. Durch diese Zentrierung erfolgt eine optimale Ausrichtung der Abrichterwelle 14 und der Abrichtrolle 12 zueinander, so dass beim Aufziehen der Abrichtrolle 12 auf den Abrichtrollenaufnahmedurchmesser D der Abrichterwelle 14 kein Verkanten der Bauteile auftritt. Mithin wird auch eine Beschädigung der hoch präzise gefertigten Abrichtrollenbohrung 25 und Abrichterwelle 14 verhindert. Zudem kann auf den Einsatz von Wärme- und/oder Kälteschränken verzichtet werden. Auch ist es möglich, die Montage der Abrichtrolle 12 innerhalb des Schleifmaschinenarbeitsraums durchzuführen, wie es in Figur 1 durch das Vorhandensein der Schleifscheibe 26 angedeutet ist. FIG. 1 shows a Abrichtrollenmontageeinrichtung 10 during installation of a dressing roller 12 on a dresser shaft 14 of a grinding wheel dressing unit, not shown. The Abrichtrollenmontageeinrichtung 10 consists of an elongate mounting sleeve 16 which is centrally provided with a through hole 18. In the in FIG. 1 illustrated state, this mounting sleeve 16 is attached to the spindle pin 20 of the dresser 14, which is received during normal operation of the grinding machine dressing in a corresponding storage. To facilitate the installation of the dressing roller 12 on the dressing roll receiving diameter D of the dresser shaft 14, the outer surface of the mounting sleeve 16 along its entire length L is provided with a conical mounting portion 22 whose outer diameter, starting from a maximum outer diameter d max in the direction of the free end 23 of the spindle pin 20 is tapered to a minimum outside diameter d min , where d max ≤ the dressing roll take-up diameter D. Accordingly, the dressing roller 12 when mounted on the mounting sleeve 16 by the interaction of the outer surface of the mounting sleeve 16 and the wall of Abrichtrollenbohrung 25 automatically with respect to the Abrichtrollenaufnahmendurchmesser D of the dresser shaft 14 centered on which the dressing roller 12 is to be finally attached. By this centering an optimal alignment of the dresser shaft 14 and the dressing roller 12 to each other, so that when mounting the dressing roller 12 on the Abrichtrollenaufnahmedurchmesser D of the dresser shaft 14 no tilting of the components occurs. Consequently, damage to the highly precisely manufactured dressing roller bore 25 and dresser shaft 14 is prevented. In addition, can be dispensed with the use of heat and / or refrigeration cabinets. It is also possible to carry out the mounting of the dressing roller 12 within the grinding machine working space as shown in FIG FIG. 1 is indicated by the presence of the grinding wheel 26.

Sobald die Abrichtrolle 12 ordnungsgemäß an der Abrichterwelle 14 positioniert ist, kann die Montagehülse 16 vom Spindelzapfen 20 abgezogen werden, so dass der Spindelzapfen 20 wieder in seiner Lagerung aufgenommen werden kann (nicht gezeigt). Zuvor wird die Abrichtrolle 12 noch mit entsprechenden Befestigungselementen (nicht gezeigt) gesichert, von denen eines auf das Außengewinde 27 der Abrichterwelle 14 aufgeschraubt wird.Once the dressing roller 12 is properly positioned on the dresser shaft 14, the mounting sleeve 16 can be withdrawn from the spindle pin 20 so that the spindle pin 20 can be re-stored (not shown). Previously, the dressing roller 12 is still secured with corresponding fastening elements (not shown), one of which is screwed onto the external thread 27 of the dresser shaft 14.

Zur Demontage der Abrichtrolle 12 wird die Montagehülse 16 wieder am Spindelzapfen 20 der Abrichterwelle 14 positioniert, so dass die Abrichtrolle 12 geführt von der Montagehülse 16 von der Abrichterwelle 14 abgezogen werden kann. Auch hierbei wird eine Beschädigung der Abrichtrollenbohrung 25 der Abrichterwelle 14 dank der Führung durch die Montagehülse 16 verhindert.To disassemble the dressing roller 12, the mounting sleeve 16 is again positioned on the spindle pin 20 of the dresser shaft 14, so that the dressing roller 12 can be pulled out of the mounting sleeve 16 guided by the dresser shaft 14. Again, damage to the Abrichtrollenbohrung 25 of the dresser shaft 14 is prevented thanks to the guide through the mounting sleeve 16.

Figur 2 zeigt eine Anordnung ähnlich wie Figur 1, wobei jedoch anstelle der Abrichtrollenmontageeinrichtung 10 eine alternative Abrichtrollenmontageeinrichtung 30 gemäß einer zweiten Ausführungsform der vorliegenden Erfindung vorgesehen ist. Die Abrichtrollenmontageeinrichtung 30 ist in Form einer länglichen Montagehülse 32 aus einer gehärteten Chrom-Nickel-Legierung vorgesehen, durch die sich zentrisch eine Durchgangsbohrung 34 erstreckt. Ebenso wie die Montagehülse 16 ist auch die Montagehülse 32 an einem Spindelzapfen 20 der Abrichterwelle 14 befestigt. Zur Erleichterung der Montage ist die Außenfläche der Montagehülse 32 mit einem konischen Montagebereich 36 versehen, der sich ausgehend von einem freien Ende der montierten Montagehülse 32 über etwa ¾ der Länge L der Montagehülse 32 erstreckt und nach und nach bis zu einem maximalen Außendurchmesser dmax aufweitet, wobei dmax ≤ dem Abrichtrollenaufnahmedurchmesser D ist. An den Montagebereich 36 schließt sich übergangslos ein Demontagebereich 38 an, dessen Außendurchmesser sich bis zum Ende der Montagehülse 32 wieder verjüngt. Der Montagebereich 36 der Montagehülse 32 entfaltet im Wesentlichen die gleiche Wirkung wie der Montagebereich 22 der Montagehülse 16 der in Figur 1 dargestellten Abrichtrollenmontageeinrichtung 10, weshalb hierauf nicht erneut eingegangen wird. Der Demontagebereich 38 der Montagehülse 16 erleichtert das Abziehen der Abrichtrolle 12 von der Abrichterwelle 14 bei der Demontage. FIG. 2 shows an arrangement similar to FIG. 1 However, instead of the dressing roll mounting device 10, an alternative dressing roll mounting device 30 according to a second embodiment of the present invention is provided. The Abrichtrollenmontageeinrichtung 30 is in the form of an elongated mounting sleeve 32 made of a hardened chromium-nickel alloy provided through which extends centrally a through hole 34. Like the mounting sleeve 16 and the mounting sleeve 32 is attached to a spindle pin 20 of the dresser 14. To facilitate assembly, the outer surface of the mounting sleeve 32 is provided with a conical mounting portion 36 extending from a free end of the assembled mounting sleeve 32 over about ¾ of the length L of the mounting sleeve 32 and gradually widens up to a maximum outer diameter d max where d max ≤ the dressing roll take-up diameter D. A disassembly area 38, whose outer diameter tapers again until the end of the mounting sleeve 32, adjoins the mounting area 36 without transition. The mounting portion 36 of the mounting sleeve 32 unfolds substantially the same effect as the mounting portion 22 of the mounting sleeve 16 of FIG FIG. 1 shown Abrichtrollenmontageeinrichtung 10, which is why will not be discussed again. The disassembly portion 38 of the mounting sleeve 16 facilitates the removal of the dressing roller 12 from the dresser shaft 14 during disassembly.
