Der Adapter für eine motorisch angetriebene Werkzeugmaschine mit drehbar anzutreibendem Werkzeug, insbesondere für eine Handwerkzeugmaschine, weist an einer ersten Stirnseite Formschlussgegenstücke auf, die an die Formschlusselemente angepasst sind, die an der Stirnseite der Werkzeugwelle angeordnet sind. An der zweiten, gegenüberliegenden Stirnseite des Adapters sind über den Umfang verteilt mehrere axial überstehende Dorne angeordnet. Diese Dorne ermöglichen einen hohen Kraftschluss sowohl in Achsrichtung als auch inThe adapter for a motor-driven machine tool with rotatably driven tool, in particular for a hand tool, has on a first end face form-fitting counterparts, which are adapted to the interlocking elements, which are arranged on the end face of the tool shaft. At the second, opposite end face of the adapter distributed over the circumference a plurality of axially projecting mandrels are arranged. These mandrels allow a high adhesion both in the axial direction and in
Umfangsrichtung zwischen der Werkzeugwelle und dem Werkzeug, der groß genug ist, um die im laufenden Betrieb auftretenden Kräfte und Momente zwischen Werkzeugwelle und Werkzeug ohne Funktionseinschränkungen übertragen zu können. Die spitz zulaufenden Dorne an einer der Stirnseiten des Adapters dringen geringfügig in den Befestigungsabschnitt des Werkzeuges ein und stellen damit in Umfangsrichtung mindestens annähernd einen Formschluss her, zumindest aber sind aufgrund des Kraftschlusses die übertragbaren Kräfte groß genug für einen ordnungsgemäßen Betrieb unter Ausschluss von in Umfangsrichtung wirkendemCircumferential direction between the tool shaft and the tool, which is large enough to transfer the forces and moments occurring during operation between the tool shaft and tool without functional restrictions. The tapered mandrels on one of the end faces of the adapter penetrate slightly into the attachment portion of the tool and thus produce at least approximately a positive fit in the circumferential direction, but at least the transferable forces are large enough for proper operation to the exclusion of circumferentially acting due to the frictional connection
Schlupf zwischen Antriebs- bzw. Werkzeugwelle und Werkzeug.Slippage between drive or tool shaft and tool.
Da der Adapter auf der der Werkzeugwelle zugewandten Seite Formschlussgegenstücke besitzt, die an die Formschlusselemente der Werkzeugwelle angepasst sind, wird auf dieser Seite ein Formschluss realisiert. Die Dorne auf der gegenüberliegenden Stirnseite des Adapters können mit verschiedenartigen Befestigungsabschnitten diverser Werkzeuge verbunden werden, ungeachtet dessen, ob diese Befestigungsabschnitte selbst mit Formschlussgegenstücken ausgestattet sind.Since the adapter has form-locking counterparts on the side facing the tool shaft which are adapted to the positive-locking elements of the tool shaft, a positive connection is realized on this side. The mandrels on the opposite end of the adapter can with various types Attachment sections of various tools are connected, regardless of whether these attachment portions are themselves equipped with form-fitting counterparts.
Für eine sichere Befestigung insbesondere in Achsrichtung zwischen dem Werkzeug und der Werkzeugwelle ist der Adapter ringförmig ausgebildet und weist eine zentrale Ausnehmung zur Aufnahme eines Sicherungselementes, beispielsweise einer Sicherungsschraube auf. Diese zentrale Ausnehmung wird von einem Stutzen begrenzt, der sich vorteilhafterweise in Achsrichtung gesehen über die die Dorne aufweisende Stirnseite erhebt, wobei die Dorne vorzugsweise einen kleineren axialen Überstand gegenüber der Stirnseite aufweisen als der Stutzen. In der Betriebsposition ragt der überstehende Stutzen in eine korrespondierende Ausnehmung im Befestigungsabschnitt des Werkzeuges ein, so dass die Stirnfläche desFor a secure attachment, in particular in the axial direction between the tool and the tool shaft of the adapter is annular and has a central recess for receiving a securing element, for example a locking screw. This central recess is delimited by a neck, which advantageously rises in the axial direction beyond the mandrels having end face, wherein the mandrels preferably have a smaller axial projection relative to the end face than the neck. In the operating position, the projecting connecting piece protrudes into a corresponding recess in the fastening section of the tool, so that the end face of the
Befestigungsabschnittes in Anlage mit den Spitzen der Dorne gelangt. Der axiale Überstand des Stutzens bezogen auf die Dorne stellt zugleich eine Sicherheitsmaßnahme gegen unbeabsichtigtes Verkratzen empfindlicher Oberflächen für den Fall einer Ablage des Adapters mit den Dornen nach unten dar, da der Adapter auf dem Stutzen abgelegt wird und die Spitzen der Dorne mit geringfügigem Abstand zur Ablagefläche liegen.Attachment section comes into contact with the tips of the mandrels. The axial projection of the nozzle relative to the mandrels at the same time represents a safety measure against accidental scratching of sensitive surfaces in the event of a filing of the adapter with the thorns down, since the adapter is placed on the neck and the tips of the mandrels with a small distance to the shelf lie.
Die Dorne, welche bevorzugt einteilig mit dem Adapter ausgebildet sind, weisen zweckmäßig eine konische Form auf, wobei grundsätzlich auch andere Geometrien für die Dorne in Betracht kommen, solange diese mit einer Spitze versehen sind. Gemäß einer weiteren zweckmäßigen Ausführung sind die Dorne von einer ringförmigen Vertiefung umgeben, die bezogen auf die die Dorne aufweisende Stirnseitenebene axial zurückgesetzt ist. Diese Vertiefung ermöglicht die Aufnahme von Schmutz- und Staubpartikeln von dem Befestigungsabschnitt des Werkzeuges, wodurch ein besserer Kontakt zwischen den Dornen und der Oberfläche des Befestigungsabschnittes auch im verschmutztenThe mandrels, which are preferably formed integrally with the adapter, expediently have a conical shape, in principle, other geometries for the mandrels come into consideration, as long as they are provided with a tip. According to a further advantageous embodiment, the mandrels are surrounded by an annular recess which is axially set back relative to the mandrels having front side plane. This recess allows the inclusion of dirt and dust particles from the mounting portion of the tool, whereby a better contact between the spines and the surface of the mounting portion in the polluted
Zustand gewährleistet ist. Die axiale Tiefe der Vertiefung, die sich in Gegenrichtung zu den Dornen erstreckt, ist - A -Condition is guaranteed. The axial depth of the recess extending in the opposite direction to the spines is - A -
vorteilhafterweise geringer als dir axiale Überstand der Dorne und beträgt beispielsweise etwa die Hälfte der Erhebung der Dorne .advantageously less than you axial projection of the mandrels and is for example about half of the survey of the mandrels.
Um eine feste Verbindung zwischen Adapter und Werkzeug im Sinne eines Zwangs- bzw. Quasi-Formschlusses herzustellen, sind über den Umfang eine Mehrzahl insbesondere gleichartig aufgebauter Dorne am Adapter vorgesehen. Jeweils mehrere Dorne können in Radialrichtung gesehen hintereinander liegend angeordnet sein, und zwar über den Umfang verteilt in einer Mehrzahl derartiger radialer Reihen. Beispielsweise ist jeweils eine Radialreihe mit Dornen zwischen zwei benachbarten Formschlussgegenstücken im Adapter angeordnet, so dass die Anzahl der Reihen mit Dornen identisch ist mit der Anzahl an Formschlussgegenstücken im Adapter.In order to produce a firm connection between the adapter and the tool in the sense of a forced or quasi-positive connection, a plurality of in particular identically constructed mandrels are provided on the adapter over the circumference. In each case a plurality of mandrels can be arranged lying one behind the other in the radial direction, distributed over the circumference in a plurality of such radial rows. For example, in each case a radial row with thorns between two adjacent form-fitting counterparts is arranged in the adapter, so that the number of rows of thorns is identical to the number of form-fitting counterparts in the adapter.
Des Weiteren kann es zweckmäßig sein, die Formschlussgegenstücke im Adapter als Ausnehmungen auszubilden, die zur Aufnahme der üblicherweise als Erhebungen ausgebildeten Formschlusselemente an der Stirnseite der Werkzeugwelle dienen. Um den Adapter an verschiedenartige Werkzeugwellen mit unterschiedlichen Formschlussmustern an der Stirnseite anschließen zu können, weisen die den Formschlusselementen zugeordneten Ausnehmungen im Adapter vorteilhafterweise eine in Radialrichtung längliche Form auf, so dass unterschiedlich geformte Erhebungen an der Stirnseite der Werkzeugwelle bzw. Erhebungen in unterschiedlichem radialen Abstand zur Wellenachse von dem Lochmuster im Adapter aufgenommen werden können. Um in Umfangsrichtung jegliches Spiel zu vermeiden, ist die Erstreckung der Ausnehmungen in Umfangsrichtung an die entsprechende Erstreckung der Erhebungen an der Stirnseite der Werkzeugwelle angepasst.Furthermore, it may be expedient to form the form-fitting counterparts in the adapter as recesses which serve to receive the form-locking elements, which are usually formed as elevations, on the end face of the tool shaft. In order to be able to connect the adapter to various tool shafts with different positive locking patterns on the front side, the recesses in the adapter assigned to the interlocking elements advantageously have an elongate shape in the radial direction, so that differently shaped elevations on the front side of the tool shaft or elevations at different radial distances from the Shaft axis can be absorbed by the hole pattern in the adapter. In order to avoid any play in the circumferential direction, the extent of the recesses in the circumferential direction is adapted to the corresponding extension of the elevations on the end face of the tool shaft.

The task of the adapter 9 is to connect different tools with different mounting portions with the abutment flange 2 of the tool shaft.
Hierzu weist der Adapter 9 Ausnehmungen 10 auf, die die Funktion von Formschlussgegenstücken haben und zur Aufnahme der als Erhebung ausgeführten Formschlusselemente 3 am Anlageflansch 2 der Werkzeugwelle 1 dienen. Die Ausnehmungen 10 sind über den Umfang verteilt gleichmäßig angeordnet und besitzen jeweils eine in Radialrichtung längliche Form, die Ausnehmungen 10 sind somit in Radialrichtung länger ausgebildet als die Erhebungen 3, wohingegen in Umfangsrichtung die Breite der Ausnehmungen 10 an den Durchmesser der Erhebungen 3 angepasst ist. Dadurch kann der Adapter 9 mit unterschiedlich ausgebildeten Anlageflanschen verbunden werden, die sich beispielsweise im Hinblick auf die Form der Formschlusselemente 3 oder im radialen Abstand der Formschlusselemente zur Wellenachse unterscheiden. Die Ausnehmungen 10 im Adapter 9 durchdringen in Achsrichtung die Wandung des Adapters 9 vollständig.For this purpose, the adapter 9 recesses 10, which have the function of form-fitting counterparts and are used to hold the designed as a survey form-locking elements 3 on the abutment flange 2 of the tool shaft 1. The recesses 10 are distributed uniformly over the circumference and each have a radially elongated shape, the recesses 10 are thus formed longer in the radial direction than the elevations 3, whereas in the circumferential direction, the width of the recesses 10 is adapted to the diameter of the elevations 3. As a result, the adapter 9 can be connected to differently shaped abutment flanges which, for example, with regard to the shape of the interlocking elements 3 or in the radial distance of Distinguish positive-locking elements to the shaft axis. The recesses 10 in the adapter 9 penetrate in the axial direction, the wall of the adapter 9 completely.
Des Weiteren sind am Adapter 9 die Dorne 11 angeordnet, die über Ebene der Stirnseite 13 (Fig. 4) axial überstehen. Über den Umfang verteilt sind eine Vielzahl derartiger Dorne 11 vorgesehen; wie aus Fig. 3 ersichtlich, können jeweils mehrere Dorne 11 in einer Radialreihe hintereinander liegend angeordnet sein, wobei jeweils eine derartige, sich in Radialrichtung erstreckende Reihe von Dornen 11 zwischen je zwei benachbarten Ausnehmungen 10 zur Aufnahme der Formschlusselemente liegen.Furthermore, the mandrels 11 are arranged on the adapter 9 and protrude axially beyond the plane of the end face 13 (FIG. 4). Distributed over the circumference a plurality of such mandrels 11 are provided; As can be seen from FIG. 3, a plurality of mandrels 11 can each be arranged lying one behind the other in a radial row, wherein in each case one such radially extending row of mandrels 11 is located between each two adjacent recesses 10 for receiving the interlocking elements.
In den Adapter 9 ist eine zentrale Ausnehmung 12 eingebracht, die an die Gewindebohrung 4 im Anlageflansch 2 der Werkzeugwelle 1 angepasst ist. Diese zentrale Ausnehmung 12 ist von einem Stutzen 14 eingefasst, der sich axial ebenfalls über die die Dorne 11 aufnehmende Stirnseite 13 erhebt. Der Stutzen 14 weist bezogen auf die Ebene der Stirnseite 13 eine größere axiale Erhebung auf als die Dorne 11.In the adapter 9, a central recess 12 is inserted, which is adapted to the threaded bore 4 in the abutment flange 2 of the tool shaft 1. This central recess 12 is bordered by a connecting piece 14 which also rises axially above the end face 13 receiving the pins 11. The nozzle 14 has, relative to the plane of the end face 13, a larger axial elevation than the mandrels 11.
Auf der der Stirnseite 13 gegenüberliegenden Seite ist am Adapter 9 ein Kragen 15 angeordnet, der radial außen liegend positioniert ist und an der Stirnseite 16 des Adapters einen Aufnahmeraum radial begrenzt, der zur Aufnahme desOn the opposite side of the end face 13, a collar 15 is arranged on the adapter 9, which is positioned radially outwardly and radially bounded on the end face 16 of the adapter a receiving space, which is for receiving the
Anlageflansches 2 der Werkzeugwelle 1 vorgesehen ist.Investment flange 2 of the tool shaft 1 is provided.
Wie der Ausschnittvergrößerung gemäß Fig. 5 zu entnehmen, besitzen die Dorne 11 Konusform. Außerdem ist eine die Dorne 11 umgreifende, ringförmige Vertiefung 17 in die Stirnseite 13 eingebracht, die gegenüber der Ebene der Stirnseite 13 axial zurückgesetzt ist. Diese Vertiefung 17 besitzt - bezogen auf die Ebene der Stirnseite 13 - eine geringere axiale Erstreckung als der Dorn 11. Bezogen auf die Stirnseite 13 ist die Tiefe der Vertiefung 17 etwa halb so groß wie die Erhebung des Dornes 11. Zweckmäßigerweise besteht der Adapter 9 aus einem magnetischen Werkstoff, wodurch die Montage des Adapters am Anlageflansch der Werkzeugwelle einerseits sowie die Befestigung des Werkzeugs am Adapter andererseits vereinfacht wird. As can be seen from the detail enlargement according to FIG. 5, the mandrels 11 have a cone shape. In addition, a mandrel 11 encompassing, annular recess 17 is introduced into the end face 13, which is axially offset from the plane of the end face 13. This recess 17 has - with respect to the plane of the end face 13 - a smaller axial extent than the mandrel 11. Based on the end face 13, the depth of the recess 17 is about half as large as the elevation of the mandrel eleventh Conveniently, the adapter 9 is made of a magnetic material, whereby the mounting of the adapter on the abutment flange of the tool shaft on the one hand and the attachment of the tool to the adapter on the other hand is simplified.
