Description

Die Erfindung betrifft eine Steckhülse zur Aufnahme eines Werkzeugs wie z.B. eines Fräswerkzeug für eine Fräsmaschine oder eines Bohrers für eine Bohrmaschine. Die Steckhülse besteht aus einem inneren Hülsenteil und einem darauf aufschiebbaren, anliegenden äußeren Hülsenteil, wobei beide Hülsenteile eine Umfangswand und eine Bodenwand haben.The invention relates to a receptacle for receiving a tool, such as a tool. a milling tool for a milling machine or a drill for a drilling machine. The plug-in sleeve consists of an inner sleeve part and a push-on thereto, adjacent outer sleeve part, wherein both sleeve parts have a peripheral wall and a bottom wall.

Wenn aus den bisher bekannten Steckhülsen dieser Art das innen liegende Werkzeug entnommen werden soll, werden die beiden Hülsenteile in axialer Richtung auseinander gezogen und dadurch voneinander getrennt. Da die beiden Hülsenteile in der Ausgangslage durch den Eingriff von Rastnoppen lösbar fixiert sind, werden die beiden Hülsenteile häufig mit beträchtlicher Kraft rasch auseinander gezogen, wobei das Werkzeug aus der Steckhülse zu Boden fallen und dabei beschädigt werden kann.If the inner tool is to be removed from the previously known sockets of this type, the two sleeve parts are pulled apart in the axial direction and thereby separated from each other. Since the two sleeve parts are releasably fixed in the initial position by the engagement of locking knobs, the two sleeve parts are often pulled apart with considerable force quickly, the tool falling from the socket to the ground and can be damaged.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Steckhülse der betrachteten Art so weiter zu entwickeln, dass die Wahrscheinlichkeit eines derartigen Schadens signifikant verringert ist.The present invention has for its object to develop a receptacle of the type under consideration so that the likelihood of such damage is significantly reduced.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the dependent claims.

Die Erfindung sieht vor, dass eines der Hülsenteile wenigstens eine in Längsrichtung der Steckhülse verlaufende Nut aufweist, in die ein vorstehender Nocken des anderen Hülsenteils eingreift. Die Stirnwände an den Enden der Nut bilden dabei Anschläge für den wenigstens einen Nocken, so dass der Nocken nicht in axialer Richtung aus der Nut austreten kann. Außerdem sieht die Erfindung vor, dass nur an dem von dem Boden abgewandten Endbereich der wenigstens einen Nut Mittel ausgebildet sind, die einen seitlichen Austritt des Nockens aus der Nut ermöglichen, so dass nach einer Drehbewegung des äußeren Hülsenteils gegenüber dem inneren Hülsenteil der Nocken aus der Nut austritt und nun die beiden Hülsenteile in Längsrichtung voneinander trennbar sind. Die Steckhülse besteht dabei aus einem Material, das elastisch so verformbar ist, dass die beiden Hülsenteile diese Drehbewegung und das anschließende Auseinanderziehen der Hülsenteile zulässt. Ein geeignetes Material ist beispielsweise Polypropylen.The invention provides that one of the sleeve parts has at least one groove running in the longitudinal direction of the plug-in sleeve, into which groove a protruding cam of the other sleeve part engages. The end walls at the ends of the groove thereby form stops for the at least one cam, so that the cam can not escape from the groove in the axial direction. In addition, the invention provides that only at the end remote from the bottom end of the at least one groove means are formed, which allow a lateral exit of the cam from the groove, so that after a rotational movement of the outer sleeve member relative to the inner sleeve member of the cam of the Groove emerges and now the two sleeve parts are separable from each other in the longitudinal direction. The socket consists of a material that is elastically deformable so that the two sleeve parts this rotational movement and the subsequent pulling apart of the sleeve parts allows. A suitable material is for example polypropylene.

Um die beiden Hülsenteile voneinander zu trennen, muss demnach zunächst das äußere Hülsenteil bis zu dem Anschlag in axialer Richtung von dem inneren Hülsenteil zurück gezogen werden, wobei dann unter Aufbringung einer gewissen Kraft die Drehbewegung und das anschließende axiale Abziehen des äußeren Hülsenteils erfolgen kann. Bei diesem Vorgang trennen sich die beiden Hülsenteile in einer Weise, in der praktisch ausgeschlossen ist, dass das Werkstück unbeabsichtigt zu Boden fällt.In order to separate the two sleeve parts from each other, therefore, first the outer sleeve member must be pulled back to the stop in the axial direction of the inner sleeve member, in which case with the application of a certain force, the rotational movement and the subsequent axial withdrawal of the outer sleeve member can take place. In this process, the two sleeve parts separate in a manner in which it is virtually impossible that the workpiece falls unintentionally to the ground.

In einer bevorzugten Ausführungsform ist die wenigstens eine Nut bzw. rinnenförmige Vertiefung außen an bzw. in der Umfangswand des inneren Hülsenteils ausgebildet, während der wenigstens eine Nocken bzw. Vorsprung innen an der Umfangswand des äußeren Hülsenteils ausgebildet ist. Der wenigstens eine Nocken befindet sich ebenfalls an dem von dem Boden abgewandten Endbereich des äußeren Hülsenteils.In a preferred embodiment, the at least one groove or trough-shaped recess is formed on the outside or in the peripheral wall of the inner sleeve part, while the at least one cam or projection is formed on the inside of the peripheral wall of the outer sleeve part. The at least one cam is also located on the end region of the outer sleeve part facing away from the bottom.

Die Anordnung kann auch umgekehrt getroffen sein, indem der wenigstens eine Nocken außen von der Umfangswand des inneren Hülsenteils absteht, während die wenigstens eine Nut innen an bzw. in der Umfangswand des äußeren Hülsenteils ausgebildet ist.The arrangement may also be reversed, in that the at least one cam protrudes outwardly from the peripheral wall of the inner sleeve part, while the at least one groove is formed on the inside or in the peripheral wall of the outer sleeve part.

Es ist bevorzugt, dass wenigstens zwei Nuten und zwei Nocken ausgebildet sind. Diese zwei Nuten und zwei Nocken sind an gegenüber liegenden Abschnitten der Umfangswände vorgesehen.It is preferred that at least two grooves and two cams are formed. These two grooves and two cams are provided on opposite portions of the peripheral walls.

In einer besonders bevorzugten Ausführungsform, bei der die Hülsenteile eine quadratische Querschnittsform haben, sind in allen vier Wandabschnitten Nuten vorgesehen, während das andere Hülsenteil zwei Nocken enthält. Diese Ausbildung hat den Vorteil, dass die beiden Hülsenteile auf besonders einfache Weise wieder zusammengesetzt werden können, da die Nocken in jeder Umfangslage der beiden Hülsenteile beim Zusammenschieben selbsttätig in zwei Nuten gelangen bzw. einschnappen.In a particularly preferred embodiment, in which the sleeve parts have a square cross-sectional shape, grooves are provided in all four wall sections, while the other sleeve part contains two cams. This design has the advantage that the two sleeve parts can be reassembled in a particularly simple manner, since the cams in each circumferential position of the two sleeve parts when pushing together automatically get into two grooves or snap.

Die Mittel, die den Austritt des wenigstens einen Nockens aus seiner Nut ermöglichen, bestehen aus wenigstens einem schrägen Seitenwandabschnitt der Nut und/oder wenigstens einer schrägen Seitenwand des Nockens. Damit kann der Nocken bei der Drehbewegung des äußeren Hülsenteils gegenüber dem inneren Hülsenteil aus der Nut heraus gleiten, wobei sich die zugehörigen Abschnitte der Umfangswände leicht nach innen und außen verformen. Die übrigen Seitenwandabschnitte der Nut und deren Stirnwände können im rechten Winkel zur Umfangswand verlaufen. Die Ausbildung ist jedenfalls so getroffen, dass der Nocken nur in der am weitesten vorgeschobenen Lage des äußeren Hülsenteils aus der Nut austreten kann.The means which allow the exit of the at least one cam from its groove, consist of at least one oblique side wall portion of the groove and / or at least one oblique side wall of the cam. Thus, the cam during the rotational movement of the outer sleeve member relative to the inner sleeve member from sliding out of the groove, wherein deform the associated portions of the peripheral walls easily inward and outward. The remaining side wall portions of the groove and their end walls may extend at right angles to the peripheral wall. The training is in any case made such that the cam can escape from the groove only in the most advanced position of the outer sleeve part.

Mit großem Vorteil ist ferner vorgesehen, dass die Umfangswand des inneren Hülsenteils eine Anleitung zum Trennen der beiden Hülsenteile enthält, die erst dann frei liegt, wenn das äußere Hülsenteil bis zum axialen Anschlag vorgeschoben ist. Diese Anleitung zum Trennen der beiden Hülsenteile kann beispielsweise die Worte "turn and pull" enthalten oder aus zwei Pfeilen bestehen, die das Drehen und anschließende axiale Verschieben andeuten. Diese Anweisung ist erst dann sichtbar, wenn die beiden Hülsenteile tatsächlich gegeneinander drehbar sind.With great advantage, it is further provided that the peripheral wall of the inner sleeve part includes a guide for separating the two sleeve parts, which is only exposed when the outer sleeve part is advanced to the axial stop. For example, these instructions for separating the two sleeve parts may include the words "turn and pull" or consist of two arrows indicating the rotation and subsequent axial displacement. This instruction is only visible when the two sleeve parts are actually rotatable against each other.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, dass die beiden Hülsenteile einen eingezogenen Boden mit einem äußeren Steg aufweisen. Dieser Steg verläuft bevorzugt diagonal über den Boden. Wenn - wie dies bevorzugt ist - die Hülsenteile im Extrusionsblasformverfahren hergestellt werden, bewirkt diese diagonale Formtrennung mit einem entsprechend dimensionierten Quetschsteg einen wirkungsvollen Aufschlagschutz für verpackte Werkzeuge, da der Quetschbalken unter dem eingezogenen Boden einen Schlag abfedern kann.In a further embodiment of the invention it is proposed that the two sleeve parts have a recessed bottom with an outer web. This bridge preferably runs diagonally across the ground. If - as is preferred - the sleeve parts are produced in the extrusion blow molding process, this diagonal mold separation with a suitably sized Quetschsteg causes an effective impact protection for packaged tools, since the Quetschbalken can absorb a shock under the retracted soil.

Wie bereits oben erwähnt, haben die Hülsenteile bevorzugt eine quadratische Querschnittsform, deren Ecken abgeschrägt sein können. Grundsätzlich kann die Steckhülse aber auch eine andere Querschnittsform haben, beispielsweise rund, oval oder allgemein rechteckig sein.As already mentioned above, the sleeve parts preferably have a square cross-sectional shape, the corners of which can be bevelled. In principle, however, the plug-in sleeve can also have a different cross-sectional shape, for example round, oval or generally rectangular.

An den abgeschrägten Ecken des inneren Hülsenteils sind zweckmäßigerweise voneinander beabstandete Rastnoppen vorgesehen, während an den Ecken des äußeren Hülsenteils mehrere kleine Stege ausgebildet sein können. Die Rastnoppen und Stege greifen ineinander ein, wodurch die jeweils ausgewählte Länge der Steckhülse lösbar fixiert ist, d.h. die Stege können über die Rastnoppen in die gewünschte Position gleiten. Damit kann die Steckhülse an die Länge des jeweiligen Werkzeugs angepasst werden.At the beveled corners of the inner sleeve member expediently spaced locking nubs are provided, while at the corners of the outer sleeve member a plurality of small webs may be formed. The locking nubs and webs engage each other, whereby the respective selected length of the plug-in sleeve is releasably fixed, i. the webs can slide over the locking knobs in the desired position. Thus, the socket can be adapted to the length of the respective tool.

Der Vorteil einer quadratischen oder rechteckigen Querschnittsform der Steckhülse besteht darin, dass die Steckhülse nicht auf einer Unterlage rollen und evtl. von einem Tisch fallen kann und dass solche Steckhülsen gut stapelbar sind.The advantage of a square or rectangular cross-sectional shape of the receptacle is that the receptacle does not roll on a pad and may possibly fall from a table and that such receptacles are well stackable.

Das in Figur 1 dargestellte innere Hülsenteil 1 hat eine im wesentlichen quadratische Zylinderform mit abgeschrägten Ecken 2. In allen vier Seitenwandabschnitten 3 ist eine in Längsrichtung verlaufende Nut bzw. rinnenförmige Vertiefung 4 ausgebildet, die im Abstand von der Bodenwand 5 und dem freien Ende 6 des Hülsenteils 1 endet. Die stirnseitigen Enden 7 der Nuten 4 verlaufen etwa im rechten Winkel zu den seitlichen Wandabschnitten 3. Zumindest eine Längswand 8 der Nuten 4 verläuft ebenfalls senkrecht zur Umfangswand. Dies ist die Seitenwand der Nuten 4, aus der die weiter unten beschriebenen Nocken 9 austreten können, indem im Bereich der als Anschlag dienenden Stirnwand 7 der Nuten 4 schräge Wandabschnitte 10 ausgebildet sind, über die die Nocken 9 durch Drehen des äußeren Hülsenteils 11 gleiten können.This in FIG. 1 In all four side wall sections 3, a groove extending in the longitudinal direction or groove-shaped recess 4 is formed, which ends at a distance from the bottom wall 5 and the free end 6 of the sleeve part 1. The front ends 7 of the grooves 4 extend approximately at right angles to the lateral wall sections 3. At least one longitudinal wall 8 of the grooves 4 also extends perpendicular to the peripheral wall. This is the side wall of the grooves 4, from which the cam 9 described below can emerge by 4 inclined wall sections 10 are formed in the region of serving as a stop end wall 7 of the grooves over which the cam 9 can slide by rotating the outer sleeve member 11 ,

An den schrägen Ecken 2 des inneren Hülsenteils 1 sind zahlreiche voneinander beabstandete Noppen 12 ausgebildet, die mit drei kleinen Stegen 13 zusammenwirken, um die jeweils gewünschte Länge der zusammengesetzten Steckhülse lösbar fixieren zu können.At the oblique corners 2 of the inner sleeve part 1 numerous spaced nubs 12 are formed, which cooperate with three small webs 13 to fix the respective desired length of the composite socket detachably.

Die dargestellte Ausführungsform ist im Extrusionsblasformverfahren hergestellt mit einer diagonalen Formtrennung 14, bei der unter der leicht nach innen gewölbten Bodenwand 15 ein Quetschsteg 16 ausgebildet ist (Figur 7). Der verhältnismäßig lange Quetschsteg 16 ermöglicht zusammen mit der eingezogenen Form des Bodens 15 eine Federwirkung, die ein in die Steckhülse aufgenommenes Werkzeug bei einem harten Aufprall vor Beschädigung schützt.The illustrated embodiment is produced by an extrusion blow molding process with a diagonal mold separation 14 in which a pinch web 16 is formed under the slightly inwardly curved bottom wall 15 ( FIG. 7 ). The relatively long Quetschsteg 16 allows together with the retracted shape of the bottom 15 has a spring action that protects a tool received in the receptacle in a hard impact from damage.

Das äußere Hülsenteil 11 hat ebenfalls eine quadratische Zylinderform mit etwas größeren Abmessungen, so dass das äußere Hülsenteil 11 so auf das innere Hülsenteil 1 aufgeschoben sein kann, dass die Teile praktisch aneinander anliegen. Das äußere Hülsenteil 11 enthält an zwei gegenüberliegenden Seitenwänden jeweils nach innen ragende Nocken 9, deren Position mit zwei Nuten 4 in Umfangsrichtung übereinstimmt. Die Nocken 9 haben eine im rechten Winkel zur Umfangswand verlaufende Stirnwand 17 und an der gegenüber liegenden Seite eine Schräge 18. Die Stirnwand 17 begrenzt das anfängliche Auseinanderziehen der Hülsenteile 1 und 11, indem sie an der vorderen Stirnwand 7 der jeweiligen Nut 4 anstößt. Die rückwärtige Schräge 18 erleichtert hingegen das Zusammensetzen der Hülsenteile.The outer sleeve part 11 also has a square cylindrical shape with slightly larger dimensions, so that the outer sleeve part 11 can be pushed onto the inner sleeve part 1 so that the parts practically abut each other. The outer sleeve member 11 includes on two opposite side walls in each case inwardly projecting cam 9, the position of which coincides with two grooves 4 in the circumferential direction. The cams 9 have a right angle to the peripheral wall extending end wall 17 and on the opposite side a slope 18. The end wall 17 limits the initial pulling apart of the sleeve parts 1 and 11 by abutting the front end wall 7 of the respective groove 4. The rear slope 18, however, facilitates the assembly of the sleeve parts.

Wenn das in der Steckhülse befindliche Werkzeug entnommen werden soll, wird das äußere Hülsenteil bis zum Anschlag axial verschoben, was in den Figuren 3, 6 und 8 dargestellt ist. In dieser Lage wird die Aufschrift "turn and pull" an einer Außenwand 3 des inneren Hülsenteils 1 sichtbar. Wenn nun das äußere Hülsenteil 11 gegenüber dem inneren Hülsenteil 1 in Richtung des Pfeils 19 in Figur 8 gedreht wird, gleiten die Noppen 9 über die schrägen Abschnitte 10 am Endbereich der Nuten 4 hinweg. Nun kann das äußere Hülsenteil 11 in Richtung des Pfeils 20 in Figur 8 von dem inneren Hülsenteil 1 abgezogen werden.When the tool located in the receptacle is to be removed, the outer sleeve member is displaced axially to the stop, which in the Figures 3 . 6 and 8 is shown. In this position, the inscription "turn and pull" on an outer wall 3 of the inner sleeve part 1 is visible. Now, if the outer sleeve member 11 relative to the inner sleeve member 1 in the direction of arrow 19 in FIG. 8 is rotated, the nubs 9 slide over the inclined portions 10 at the end portion of the grooves 4 away. Now, the outer sleeve member 11 in the direction of arrow 20 in FIG. 8 be deducted from the inner sleeve part 1.
