Description

Die Erfindung betrifft ein Befestigungssystem zur Befestigung eines Werkzeugs an einer Werkzeugaufnahme, umfassend das Werkzeug und einen Werkzeugschlüssel, wobei das Werkzeug ein Innengewinde aufweist, mittels dem es auf einen an der Werkzeugaufnahme vorgesehenen Gewindebolzen aufschraubbar ist und wobei das Werkzeug um seine Achse herum angeordnete Betätigungsabschnitte aufweist, die beim Aufschrauben des Werkzeugs zur Drehmomentübertragung mit am Werkzeugschlüssel vorgesehenen Vorsprüngen zusammenwirkenThe invention relates to a fastening system for fastening a tool to a tool holder, comprising the tool and a tool wrench, the tool having an internal thread by means of which it can be screwed onto a threaded bolt provided on the tool holder and wherein the tool has actuating sections arranged around its axis which interact with projections provided on the tool wrench for torque transmission when the tool is screwed on

Ein derartiges Befestigungssystem ist beispielsweise aus der DE 10 2014 225 909 B3 bekannt. Die Werkzeugaufnahme kann dabei an eine Antriebsspindel einer Werkzeugmaschine angeordnet werden. Das Werkzeug dient dann zur spanabhebenden Bearbeitung und weist Schneidelemente auf, die an der Stirnseite des Werkzeugs und/oder an dessen Umfang vorgesehen sein können. Zur sicheren Befestigung des Werkzeugs an der Werkzeugaufnahme wird das Werkzeug mit vergleichsweise hohen Drehmomenten auf die Werkzeugaufnahme aufgeschraubt. Je nach Durchmesser des vorzusehenden Werkzeuges können Drehmomente erforderlich werden, die im Bereich von 100 Nm oder höher liegen. Bei den Werkzeugen handelt es sich insbesondere um Präzisionswerkzeuge, mit denen eine hochgenaue Bearbeitung eines Werkstücks möglich ist. Insofern ist ein sicheres Austauschen des Werkzeugs an der Werkzeugaufnahme bereitzustellen, ohne dass das Werkzeug, bzw. dessen Betätigungsabschnitte beim Aufschrauben oder Abschrauben des Werkzeugs an der Werkzeugaufnahme beschädigt wird.Such a fastening system is for example from DE 10 2014 225 909 B3 known. The tool holder can be arranged on a drive spindle of a machine tool. The tool is then used for machining and has cutting elements that can be provided on the end face of the tool and / or on its circumference. For secure attachment of the tool to the tool holder, the tool is screwed onto the tool holder with comparatively high torques. Depending on the diameter of the tool to be provided, torques in the range of 100 Nm or higher may be required. The tools are, in particular, precision tools with which high-precision machining of a workpiece is possible. In this respect, a reliable exchange of the tool on the tool holder is to be provided without the tool or its actuation sections being damaged when the tool is screwed on or unscrewed from the tool holder.

Ein als geschlossener Ringschlüssel ausgebildeter Werkzeugschlüssel ist beispielsweise aus der DE 10 2014 225 916 B4 bekannt.A tool wrench designed as a closed ring wrench is, for example, from DE 10 2014 225 916 B4 known.

Weitere Werkzeugschlüssel sind beispielsweise bekannt aus der US 2 830 480 A , der US 2016/0339563 A1 , der US 9 452 511 B2 und der DE 24 56 668 A1 .Further tool keys are known, for example, from U.S. 2,830,480 A , the US 2016/0339563 A1 , the US 9 452 511 B2 and the DE 24 56 668 A1 .

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein eingangs beschriebenes Befestigungssystem bereitzustellen, bei dem das Werkzeug sicher und beschädigungsfrei an der Werkzeugaufnahme befestigt und wieder gelöst werden kann.The present invention is based on the object of providing a fastening system as described in the introduction, in which the tool can be fastened to the tool holder safely and without damage and can be detached again.

Diese Aufgabe wird durch ein Befestigungssystem mit den Merkmalen des Patentanspruchs 1 gelöst. Folglich ist insbesondere vorgesehen, dass der Werkzeugschlüssel als einseitig offener Maulschlüssel ausgebildet ist, an dessen Innenumfang die Vorsprünge entlang einer Kreisbahn vorgesehen sind, wobei sich die Kreisbahn mit den Vorsprüngen über einen Winkelbereich erstreckt, der größer als 180° ist.This object is achieved by a fastening system with the features of claim 1. Consequently, it is particularly provided that the tool wrench is designed as a spanner open on one side, on the inner circumference of which the projections are provided along a circular path, the circular path with the projections extending over an angular range that is greater than 180 °.

Dadurch, dass der Werkzeugschlüssel als Maulschlüssel ausgebildet ist, kann er von der Seite her an das Werkstück herangeführt werden. Der Werkzeugschlüssel hat dabei die Besonderheit, dass die Vorsprünge sich nicht nur über einen Winkelbereich von 180° erstrecken, sondern über einen Winkelbereich, der größer als 180° ist. Dadurch kann ein Abrutschen des Werkzeugschlüssels am Werkstück sicher verhindert werden. Anders als bei einem Gabelschlüssel, der ein Maul mit zwei parallel zueinander vorgesehenen Anlageflächen aufweist, die sich letztlich über einen Winkelbereich von nur 180° erstrecken, wird hier das Werkstück, bzw. dessen Betätigungsabschnitte sicher umschlossen. Hierdurch kann das Werkstück mit entsprechend hohen Drehmomenten an der Werkstückaufnahme befestigt werden, ohne dass es zu Beschädigungen an den Befestigungsabschnitten und/oder am Werkzeugschlüssel kommt.Because the tool wrench is designed as an open-end wrench, it can be brought up to the workpiece from the side. The special feature of the tool wrench is that the projections not only extend over an angular range of 180 °, but also over an angular range that is greater than 180 °. This can reliably prevent the tool wrench from slipping on the workpiece. In contrast to an open-end wrench, which has a jaw with two contact surfaces provided parallel to one another, which ultimately extend over an angular range of only 180 °, this is the case here Workpiece or its actuation sections safely enclosed. As a result, the workpiece can be fastened to the workpiece holder with correspondingly high torques without damage to the fastening sections and / or to the tool wrench.

Vorteilhafterweise ist der Winkelbereich größer als 190° und liegt weiter vorzugsweise im Bereich zwischen 190° und 270° und weiter vorzugsweise im Bereich zwischen 200° und 250° und weiter im Bereich von 230°. Durch Vorsehen eines derartigen Winkelbereichs ergibt sich ein ausreichendes Umschließen des Werkzeugschlüssels um die Betätigungsabschnitte des Werkzeugs.The angular range is advantageously greater than 190 ° and is more preferably in the range between 190 ° and 270 ° and more preferably in the range between 200 ° and 250 ° and further in the range of 230 °. By providing such an angular range, the tool wrench is adequately enclosed around the actuation sections of the tool.

Erfindungsgemäß ist ferner vorgesehen, dass das Werkzeug in dem den Betätigungsabschnitten benachbarten Bereichen eine Einschnürung aufweist, die einen Durchmesser vorsieht, der geringfügig kleiner ist als das Öffnungsmaß des Maulschlüssels ist. Das Öffnungsmaß des Maulschlüssels ist folglich das Maß des geringsten Abstandes der beiden freien Endbereich der Maulöffnung. Dadurch kann erreicht werden, dass der Maulschlüssel von der Seite her im Bereich der Einschnürung auf das Werkstück aufgeschoben werden kann, und dann, wenn der Maulschlüssel die Einschnürung umgibt, in axialer Richtung hin zu den Betätigungsabschnitten bewegt werden kann, so dass letztlich die Vorsprünge mit den Betätigungsabschnitten in Eingriff gelangen. Dadurch können insbesondere Werkzeuge vorgesehen werden, die eine Aufnahme für die Schneidelemente aufweisen, welche einen Durchmesser aufweist, der deutlich größer sein kann als der Durchmesser des Werkzeugs im Bereich der Betätigungsabschnitte. Folglich können insbesondere kelchartige Werkzeuge bereitgestellt werden, die im Bereich ihrer Schneidelemente einen vergleichsweise großen Durchmesser und die im Bereich der Betätigungsabschnitte einen deutlich geringeren Durchmesser aufweisen. Dennoch können diese Werkzeuge mit dem entsprechenden Werkzeugschlüssel mit vergleichsweise hohen Drehmomenten an der Werkzeugaufnahme befestigt werden.According to the invention it is further provided that the tool has a constriction in the areas adjacent to the actuating sections, which provides a diameter that is slightly smaller than the opening dimension of the open-ended wrench. The opening dimension of the wrench is consequently the dimension of the smallest distance between the two free end regions of the mouth opening. It can thereby be achieved that the wrench can be pushed onto the workpiece from the side in the area of the constriction and, when the wrench surrounds the constriction, can be moved in the axial direction towards the actuation sections, so that ultimately the projections with engage the operating sections. As a result, tools can in particular be provided which have a receptacle for the cutting elements which has a diameter which can be significantly larger than the diameter of the tool in the area of the actuating sections. As a result, cup-like tools in particular can be provided which have a comparatively large diameter in the area of their cutting elements and which have a significantly smaller diameter in the area of the actuating sections. Nevertheless, these tools can be attached to the tool holder with the corresponding tool wrench with comparatively high torques.

Weiterhin ist der Werkzeugschlüssel so aufgebaut, dass die Vorsprünge auf der Kreisbahn entlang eines in axialer Richtung betrachteten, ersten Abschnitts liegen und dass sich an diesen ersten Abschnitt in axialer Richtung ein zweiter Abschnitt anschließt, welcher keine Vorsprünge aufweist. Dieser zweite Abschnitt kann zur Stabilität des Werkzeugschlüssels und einer homogenen Kraftverteilung beim Aufbringen des Drehmoments im Werkzeugschlüssel beitragen.Furthermore, the tool wrench is constructed in such a way that the projections lie on the circular path along a first section viewed in the axial direction and that this first section is followed in the axial direction by a second section which has no projections. This second section can contribute to the stability of the tool wrench and a homogeneous force distribution when applying the torque in the tool wrench.

Gemäß der Erfindung ist ebenfalls vorgesehen, dass die axiale Erstreckung des Maulschlüssels mit dem ersten Abschnitt und dem zweiten Abschnitt größer ist als die axiale Erstreckung der Einschnürung.According to the invention, it is also provided that the axial extent of the open-end wrench with the first section and the second section is greater than the axial extent of the constriction.

Das Öffnungsmaß des Maulschlüssels ist vorzugsweise im Bereich von 0,1 mm bis 2 mm und weiter vorzugsweise im Bereich von 0,2 mm bis 0,5 mm größer als der Durchmesser der Einschnürung. Als besonders vorteilhaft hat sich ein Wert von 0,3 mm herausgestellt. Dadurch kann zum einen der Maulschlüssel sicher in die Einschnürung eingeführt werden; dennoch können die Vorsprünge zur Übertragung des Drehmoments sicher mit den Betätigungsabschnitten zusammenwirken.The opening dimension of the wrench is preferably in the range from 0.1 mm to 2 mm and more preferably in the range from 0.2 mm to 0.5 mm larger than the diameter of the constriction. A value of 0.3 mm has proven to be particularly advantageous. In this way, on the one hand, the wrench can be safely inserted into the constriction; nevertheless, the projections for transmitting the torque can safely interact with the actuating sections.

Ferner ist vorteilhaft, wenn die Vorsprünge eine radial innere, eben ausgebildete Anlagefläche zur Anlage an die Betätigungsabschnitte aufweisen, die in einem Winkel von etwa 1° bis 3° und vorzugsweise in einem Winkel von 2° zur Mittelachse geneigt sind. Dies hat den Vorteil, dass dann, wenn der Maulschlüssel von der Einschnürung in axialer Richtung hin zu den Betätigungsabschnitten verlagert wird, die plan ausgebildeten Anlageflächen der Vorsprünge sicher an den vorzugsweise dazu komplementär ausgebildeten Betätigungsabschnitten zum Anliegen kommen.It is also advantageous if the projections have a radially inner, planar contact surface for contact with the actuating sections, which is at an angle of approximately 1 ° to 3 ° and preferably at an angle of 2 ° to the central axis. This has the advantage that when the open-ended wrench is displaced from the constriction in the axial direction towards the actuating sections, the planar contact surfaces of the projections reliably come to rest on the actuating sections, which are preferably complementary thereto.

Dabei ist vorteilhaft, wenn die Betätigungsabschnitte komplementär zu den Anlageflächen ausgebildete Ausnehmungen aufweisen. Die Ausnehmungen sind dann vorzugsweise ebenfalls eben bzw. plan ausgebildet und sind zur Mittellängsachse entsprechend geneigt. Die Vorsprünge können dann auf besonders geeignete Art und Weise in axialer Richtung in die Betätigungsabschnitte einrutschen und dort aufgrund insbesondere der geneigten und ebenen Anlageflächen sowie Ausnehmungen sicher und spielfrei zur Anlage kommen. DIt is advantageous if the actuating sections have recesses designed to be complementary to the contact surfaces. The recesses are then preferably also of planar or planar design and are correspondingly inclined to the central longitudinal axis. The projections can then slide into the actuating sections in an especially suitable manner in the axial direction and come to rest there safely and without play, in particular due to the inclined and flat contact surfaces and recesses. D.

Ferner ist vorteilhaft, wenn die Vorsprünge in Umfangsrichtung von Kanten begrenzt werden und wenn die Ausnehmungen in Umfangsrichtung von Schultern derart begrenzt werden, dass bei einer Drehmomentübertragung die Kanten mit den Schultern zusammenwirken. Hierdurch kann eine günstige Kraftübertragung bereitgestellt werden, insbesondere dann, wenn, wie oben beschrieben, geneigte Anlageflächen und entsprechend komplementär ausgebildete Ausnehmungen vorgesehen sind.It is also advantageous if the projections are delimited by edges in the circumferential direction and if the recesses are delimited by shoulders in the circumferential direction in such a way that the edges interact with the shoulders when a torque is transmitted. This makes it possible to provide a favorable force transmission, in particular when, as described above, inclined contact surfaces and correspondingly complementary recesses are provided.

Zudem ist denkbar, dass zwischen den Vorsprüngen des Werkzeugschlüssels Ausbuchtungen vorgesehen sind, wobei die Ausbuchtungen die Vorsprünge wenigstens abschnittsweise in Umfangsrichtung hinterschneiden. Dadurch kann erreicht werden, dass die Betätigungsabschnitte, und insbesondere deren Kannten, beim Aufsetzen und Abnehmen des Werkzeugschlüssels nicht beschädigt werden.It is also conceivable that bulges are provided between the projections of the tool wrench, the bulges undercut the projections at least in sections in the circumferential direction. It can thereby be achieved that the actuating sections, and in particular their Known not to be damaged when putting on and taking off the tool wrench.

Die eingangs genannte Aufgabe wird auch gelöst durch ein Werkzeug und/oder durch einen Werkzeugschlüssel eines erfindungsgemäßen Befestigungssystems.The object mentioned at the beginning is also achieved by a tool and / or by a tool wrench of a fastening system according to the invention.

Weitere Einzelheiten und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung zu entnehmen, anhand derer ein Ausführungsbeispiel der Erfindung näher beschrieben und erläutert ist.Further details and advantageous embodiments of the invention can be found in the following description, on the basis of which an exemplary embodiment of the invention is described and explained in more detail.

With the internal thread 22, the tool 10 can be screwed onto the workpiece carrier, which has a threaded bolt. When the workpiece 10 is screwed on, its underside 24 facing away from the cutting elements 12, which provides a centering cone 26, is acted upon against a complementary mating cone on the tool holder.

Das Werkzeug 10 weist im Bereich seiner Unterseite eine Mantelfläche 28 auf, an der, um die Mittelachse 14 herum angeordnete Betätigungsabschnitte 30 vorgesehen sind.In the area of its underside, the tool 10 has a lateral surface 28 on which actuating sections 30 arranged around the central axis 14 are provided.

Wie aus dem Schnitt gemäß Figur 1 deutlich wird, sind im Werkzeug 10 zudem Kühlkanäle 32 vorgesehen, durch welche im Betrieb Kühlflüssigkeit zur Kühlung des Werkzeugs 10, der Schneidelemente 12 und des zu bearbeitenden Werkstücks dienen. Die Kühlmittelkanäle 32 münden dabei in Kühlöffnungen 34.As shown in the cut Figure 1 As is clear, cooling channels 32 are also provided in the tool 10, through which cooling liquid is used to cool the tool 10, the cutting elements 12 and the workpiece to be machined during operation. The coolant channels 32 open into cooling openings 34.

Zur sicheren Befestigung des Werkzeugs 10 ist dieses mit einem entsprechend hohen Drehmoment auf die Werkzeugaufnahme aufzuschrauben. Dazu ist, wie in den Figuren 2 bis 6 dargestellt, ein Werkzeugschlüssel 36 vorgesehen.For secure fastening of the tool 10, it must be screwed onto the tool holder with a correspondingly high torque. This is how in the Figures 2 to 6 shown, a tool wrench 36 is provided.

In den Figuren 2, 3 und 4 ist das Werkzeug 10 ohne die Schneidelemente 12 gezeigt. Deutlich zu erkennen sind Plattensitze 38, an welchen die Schneidelemente 12 befestigt werden können.In the Figures 2 , 3 and 4 the tool 10 is shown without the cutting elements 12. Can be clearly seen Insert seats 38 to which the cutting elements 12 can be attached.

Wie aus den Figuren 2 bis 5 deutlich wird, ist der Werkzeugschlüssel 36 als offener Maulschlüssel, der ein Öffnungsmaß M vorsieht, ausgebildet, an dessen Innenumfang Vorsprünge 40 entlang einer Kreisbahn 42 vorgesehen sind. Insgesamt sind bei der Ausführungsform, die in den Figuren gezeigt ist, fünf Vorsprünge 40 gezeigt, die sich über einen Winkelbereich α erstrecken, der größer als 180° ist. Bei der in den Figuren gezeigten Ausführungsform beträgt der Winkelbereich α ca. 230°. Die Vorsprünge 40 sind äquidistant auf der Kreisbahn 42 zueinander angeordnet. Jeder Vorsprung 40 erstreckt sich, wie aus Figur 5 deutlich wird, über einen Winkelbereich β, der im Bereich von 25° liegt.As from the Figures 2 to 5 As is clear, the tool wrench 36 is designed as an open spanner which provides an opening dimension M, on the inner circumference of which projections 40 are provided along a circular path 42. Overall, in the embodiment shown in the figures, five projections 40 are shown, which extend over an angular range α which is greater than 180 °. In the embodiment shown in the figures, the angular range α is approximately 230 °. The projections 40 are arranged equidistantly from one another on the circular path 42. Each protrusion 40 extends, as from Figure 5 becomes clear over an angular range β which is in the range of 25 °.

Zum Ansetzen des Werkzeugschlüssels 36 am Werkzeug 10 weist das Werkzeug 10 eine in axialer Richtung benachbart zu den Betätigungsabschnitten 30 angeordnete Einschnürung 44 auf. Die Einschnürung 44 weist einen Durchmesser D auf, der geringfügig kleiner ist als das Öffnungsmaß M des Werkzeugschlüssels 36. Der Außendurchmesser A des Betätigungsabschnitts 30 ist dabei größer als der Durchmesser D sowie größer als das Öffnungsmaß M.In order to apply the tool wrench 36 to the tool 10, the tool 10 has a constriction 44 arranged in the axial direction adjacent to the actuating sections 30. The constriction 44 has a diameter D which is slightly smaller than the opening dimension M of the tool wrench 36. The outer diameter A of the actuating section 30 is greater than the diameter D and greater than the opening dimension M.

Die Vorsprünge 40 weisen jeweils eine radial innere, ebene und plane Anlagefläche 46 auf. Die Anlageflächen 46 sind dabei zur Mittelachse 48 der Kreisbahn 42 unter einem Winkel β von 1° bis 3° und insbesondere von 2° geneigt angeordnet. Dazu ist in der Figur 3 eine Gerade 50 gezeigt, die in der Ebene der Anlagefläche 46 liegt und die Mittelachse 48 unter dem Winkel β, der vorzugsweise 2° beträgt, schneidet.The projections 40 each have a radially inner, flat and planar contact surface 46. The contact surfaces 46 are inclined to the central axis 48 of the circular path 42 at an angle β of 1 ° to 3 ° and in particular 2 °. This is in the Figure 3 a straight line 50 is shown which lies in the plane of the contact surface 46 and intersects the central axis 48 at the angle β, which is preferably 2 °.

Wie ebenfalls aus den Figuren 2 und 3 deutlich wird, weisen die Betätigungsabschnitte 30 Ausnehmungen 52 auf, die komplementär zu den Vorsprüngen 40 ausgebildet sind. Die Ausnehmungen weisen folglich ebenfalls jeweils eine ebene und plane Fläche auf, die um den Winkel β zur Mittelachse 14 geneigt ist.As also from the Figures 2 and 3 As is clear, the actuating sections 30 have recesses 52 which are designed to be complementary to the projections 40. The recesses consequently also each have a flat and planar surface which is inclined at the angle β to the central axis 14.

Die werkzeugschlüsselseitigen Vorsprünge 40 sind in Umfangsrichtung von Kanten 54 begrenzt. Die werkzeugseitigen Ausnehmungen 52 sind ihrerseits in Umfangsrichtung von Schultern 56 begrenzt. Die Kanten 54 und Schultern 56 sind derart angeordnet, dass sie bei einer Drehmomentübertragung zusammenwirken.The projections 40 on the tool wrench side are delimited in the circumferential direction by edges 54. The tool-side recesses 52 are in turn bounded in the circumferential direction by shoulders 56. The edges 54 and shoulders 56 are arranged such that they cooperate in transmitting torque.

Aufgrund der beschriebenen Neigung der Anlageflächen 46 und der Flächen der Ausnehmungen 52 sowie aufgrund des passgenauen Zusammenwirkens der Kanten 54 mit den Schultern 56 kann erreicht werden, dass beim Einsetzen des Schlüssels 36, bzw. deren Vorsprünge 40, die Vorsprünge 40 auf geeignete Art und Weise in die Ausnehmungen 52 einrutschen bzw. dort sicher verharren.Due to the described inclination of the contact surfaces 46 and the surfaces of the recesses 52 as well as the precisely fitting interaction of the edges 54 with the shoulders 56, it can be achieved that when the key 36 or its projections 40 are inserted, the projections 40 are appropriately positioned slide into the recesses 52 or remain there safely.

Zum Ansetzen des Werkzeugschlüssels 36 am Werkzeug 10 wird der Werkzeugschlüssel 36 mit seiner Öffnung über die Einschnürung 44 geschoben. Danach wird der Werkzeugschlüssel 36, wie in Figur 4 dargestellt, nach axial unten verlagert, so dass die Vorsprünge 40 in die komplementär dazu ausgebildeten Ausnehmungen 52 eingreifen. Aufgrund des "satten" Anliegens der Vorsprünge 40 in den Ausnehmungen 52 kann dann in einem nächsten Schritt der Werkzeugschlüssel 36 um die Mittelachse 14 bzw. 48 zur Aufbringung eines Drehmoments verdreht werden.To apply the tool wrench 36 to the tool 10, the tool wrench 36 is pushed with its opening over the constriction 44. Then the tool wrench 36, as in Figure 4 shown, displaced axially downward, so that the projections 40 engage in the recesses 52 designed to be complementary thereto. Because the projections 40 fit snugly in the recesses 52, the tool wrench 36 can then be rotated about the central axis 14 or 48 in a next step in order to apply a torque.

Der Werkzeugschlüssel 36 sieht dabei einen Betätigungsabschnitt 58 vor, an welchem beispielsweise ein Drehmomentmesshebel zur Aufbringung und Kontrolle eines geeigneten Drehmoments angesetzt werden kann.The tool wrench 36 provides an actuation section 58 on which, for example, a torque measuring lever for applying and checking a suitable torque can be attached.

Wie aus den Figuren 5 und 6 deutlich wird, weist der Werkzeugschlüssel 36 in axialer Richtung gesehen einen ersten Abschnitt 60 auf, an welchem die Vorsprünge vorgesehen sind. Daran anschließend ist ein zweiter Abschnitt 62 vorgesehen, welcher frei von Vorsprüngen 40 ist. Die axiale Erstreckung x des Maulschlüssels mit dem ersten Abschnitt 61 und dem zweiten Abschnitt 62 größer ist als die axiale Erstreckung y der Einschnürung.As from the Figures 5 and 6 As is clear, the tool wrench 36, viewed in the axial direction, has a first section 60 on which the projections are provided. A second section 62, which is free of projections 40, is then provided. The axial extension x of the wrench with the first section 61 and the second section 62 is greater than the axial extension y of the constriction.

Wie ferner insbesondere aus Figur 5 deutlich wird, ist zwischen zwei Vorsprüngen 40 jeweils eine radial zurückversetzte Ausbuchtung 64 vorgesehen, wobei die Ausbuchtungen 64 derart sind, dass sie die Vorsprünge 40 in Umfangsrichtung geringfügig hinterschneiden. Hierdurch können beim Aufsetzen die Kanten 52 an den Betätigungsabschnitten 30 geschont werden.How further in particular from Figure 5 becomes clear, a radially set back bulge 64 is provided between two projections 40, the bulges 64 being such that they undercut the projections 40 slightly in the circumferential direction. As a result, the edges 52 on the actuating sections 30 can be spared when they are put on.

Das erfindungsgemäße Befestigungssystem mit dem Werkzeug 10 und dem zugehörigen Werkzeugschlüssel 36 hat den Vorteil, dass die Vorsprünge des Werkzeugschlüssels 36 über den Winkelbereich von 230° angeordnet sind, so dass ein Abrutschen des Schlüssels 36 von den Befestigungsabschnitten beim Betätigen des Schlüssels 36 nicht erfolgen kann. Dennoch kann der Schlüssel seitlich, über die Einschnürung 42, am Werkzeug 10 angesetzt werden und muss nicht, wie beispielsweise ein Ringschlüssel von oben oder unten in axialer Richtung, auf den entsprechend ausgebildeten Gegenabschnitt aufgesetzt werden.The fastening system according to the invention with the tool 10 and the associated tool wrench 36 has the advantage that the projections of the tool wrench 36 are arranged over the angular range of 230 °, so that the key 36 cannot slip off the fastening sections when the key 36 is actuated. Nevertheless, the key can be placed laterally, via the constriction 42, on the tool 10 and does not have to be placed on the correspondingly designed counter-section from above or below in the axial direction, for example, like a ring spanner.

Insgesamt können durch das erfindungsgemäße Befestigungssystem vergleichsweise hohe Drehmomente sicher übertragen werden. Dies hat zudem den Vorteil, dass der Bereich des Werkzeugs 10, an dem die Schneidelemente 12 vorgesehen sind, einen weitaus größeren Durchmesser aufweisen kann, als der Bereich der Einschnürung 44 bzw. der Bereich, an dem die Betätigungsabschnitte 30 vorgesehen sind.Overall, comparatively high torques can be safely transmitted by the fastening system according to the invention. This also has the advantage that the area of the tool 10 on which the cutting elements 12 are provided can have a much larger diameter than the area of the constriction 44 or the area on which the actuation sections 30 are provided.
