Abstract

The quick change drill head for a machine tool has a stub (2) extending axially to form the mounting. The stub is engaged by a sprung detent in the machine too, spindle. The stub is cylindrical with flats (3) formed on its periphery and recesses (5) angularly offset from the flats. The recesses receive the locking detent and have guide grooves (4) leading to them.

Description

Die Erfindung betrifft ein, zum Verbinden mit einer angetriebenen Schnellwechsel­ aufnahme geeignetes, Bohrwerkzeug mit den Merkmalen des Oberbegriffs des An­ spruchs 1.The invention relates to a, for connecting to a driven quick change Suitable drilling tool with the features of the generic term of the An saying 1.

Ein derartiges Werkzeug ist, z. B. aus der DE 44 22 342 A1 Fig. 9 bekannt. Dort ist die Vertiefung innerhalb der Fläche angeordnet.Such a tool is e.g. B. from DE 44 22 342 A1 Fig. 9 known. There the depression is arranged within the surface.

Der Erfindung liegt die Aufgabe zugrunde eine weitere mögliche Ausbildung des Werkzeugschafts zu schaffen.The invention has for its object a further possible training of To create tool shank.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Die Unteransprüche beinhalten weitere Ausgestaltungen der Erfindung.The subclaims contain further refinements of the invention.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbei­ spiels näher erläutert.The invention is based on an exemplary embodiment shown in the drawing explained in more detail.

In der Zeichnung zeigt:The drawing shows:

Fig. 1 eine perspektivische Darstellung des Werkzeugs Fig. 1 is a perspective view of the tool

Fig. 2 eine Seitenansicht und Fig. 2 is a side view and

Fig. 3 einen Schnitt durch den Schaft entlang der. Linie AA Fig. 3 shows a section through the shaft along the. Line AA

In der Zeichnung ist ein Werkzeug mit 1 bezeichnet. Sein Schaft 2 mit an sich kreis­ förmigem Querschnitt weist an seinem Umfang drei um 120° gegeneinander ver­ setzte Flächen 3, eine umlaufende Rille 4 und im Winkel von 60° gegenüber den Flä­ chen 3 versetzt drei Vertiefungen 5 auf. In the drawing, a tool is designated 1. His shaft 2 with a circular cross-section per se has on its circumference three by 120 ° mutually ver surfaces 3 , a circumferential groove 4 and at an angle of 60 ° to the surfaces 3 offset three wells 5 .

Die Anordnung der Flächen 3 und der Vertiefungen 5 ist besser aus der Schnitt­ zeichnung der Fig. 3 erkennbar, wobei sich aus der Zeichnung ergibt, dass die Tiefe der Riffe 4 gleich dem Abstand des tiefsten Punkts der Flächen 3 vom Umfang des Schafts 2 ist. Dies ist auch aus der Seitenansicht der Fig. 2 erkennbar.The arrangement of the surfaces 3 and the recesses 5 can be seen better from the sectional drawing of FIG. 3, which shows from the drawing that the depth of the reefs 4 is equal to the distance of the lowest point of the surfaces 3 from the circumference of the shaft 2 . This can also be seen from the side view of FIG. 2.

In Fig. 3 ist ein Arretierkörper 6 einer nicht gezeichneten aber, z. B. aus der eingangs genannten DE 44 22 342 A1 bekannten Schnellwechselaufnahme mit eingezeichnet und zwar in der Stellung die er bei der Verriegelung einnimmt.In Fig. 3 is a locking body 6 a not shown but, for. B. from the above-mentioned DE 44 22 342 A1 known quick-change receptacle with in the position he occupies when locking.

Zum Einsetzen des Bohrwerkzeugs in die Schnellwechselaufnahme wird das Bohr­ werkzeug 1 von Hand in die Öffnung der Schnellwechselaufnahme in Achsrichtung eingeführt. Hierbei werden die etwas in die Öffnung der Schnellwechselaufnahme vorstehenden Arretierkörper 6 nach einem eventuell notwendigen Verdrehen, bzw. Ausrichten des Werkzeugs zur Schnellwechselaufnahme zurückgedrängt. Die Arre­ tierkörper 6 gleiten dann entlang den Flächen 3 bis nach einem gewissen Einführweg die Rille 4 erreicht ist und ein Verdrehen des Werkzeugs 1 um 60° möglich wird. Hierbei gleiten die Arretierkörper entlang der Rille 4. Werden die Vertiefungen 5 er­ reicht, so rasten die Arretierkörper 6 ein und sie können verriegelt werden. Beim Ent­ koppeln laufen die Vorgänge in umgekehrter Reihenfolge ab.To insert the drilling tool into the quick-change holder, the drilling tool 1 is inserted by hand into the opening of the quick-change holder in the axial direction. In this case, the locking bodies 6 protruding somewhat into the opening of the quick-change receptacle are pushed back after a necessary twisting or alignment of the tool for the quick-change receptacle. The Arre carcass 6 then slide along the surfaces 3 until the groove 4 is reached after a certain insertion path and a rotation of the tool 1 by 60 ° is possible. The locking bodies slide along the groove 4 . If the wells 5 it reaches, the locking bodies 6 snap into place and they can be locked. When decoupling, the processes take place in reverse order.
