Description

Werkzeugaufnahme an der Spindel einer Bohrmaschine od. dgl.Tool holder on the spindle of a drill or the like.

mit einem an der Spindel angeordneten Austreiberschlitz Die Erfindung bezieht sich auf die Werkzeugaufnahme an der Spindel einer Bohrmaschine od. dgl. zur Aufnahme von mit einem Mitnehmerlappen versehenen, konischen Werkzeugschäften mit einem an der Spindel angeordneten Austreiberschlitz.with an ejector slot arranged on the spindle. The invention relates to the tool holder on the spindle of a drill or the like. for holding conical tool shanks provided with a driver tab with an ejector slot arranged on the spindle.

Der Erfindung liegt die Aufgabe zugrunde, die Werkzeugaufnahme so auszubilden, daß Beschädigungen, die durch abgescherte Mitnehmerlappen auftreten, grundsätzlich verhindert werden.The invention is based on the object of the tool holder so to train that damage caused by sheared driving tabs, be prevented in principle.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Austreiberschlitz in der Spindel an den beiden Enden eine Sperre aufweist.This object is achieved according to the invention in that the ejector slot has a lock in the spindle at both ends.

In Weiterbildung des Erfindungsgegenstandes kann die Sperre aus an den Seitenflächen des Austreiberschlitzes angeordneten Wülsten, Kugeln oder Stiften bestehen.In a further development of the subject matter of the invention, the lock can be turned on the side surfaces of the ejector slot arranged beads, balls or pins exist.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt; es zeigt Fig. 1 einen Längsschnitt durch die Lagerung einer Bohrspindel mit Austreiberschlitz; Fig. 2 einen Schnitt nach der Linie A B der Fig. 1. Der Werkzeugschaft 1 ist in an sich bekannter Weise mit einem Konus 1' zum Befestigen in der Werkzeugspindel 2 versehen. Der konusförmige Schaftteil endet in einem Mitnehmerlappen 1", der im Austreiberschlitz 2' der Bohrspindel 2 mit Spiel sitzt und unter anderem die Aufgabe hat, vom Schlitz 2' der Bohrspindel 2 das Drehmoment auf den Werkzeugschaft zu übertragen.In the drawing, an embodiment of the subject of the invention is shown; 1 shows a longitudinal section through the mounting of a drilling spindle with an ejector slot; FIG. 2 shows a section along the line AB in FIG. 1. The tool shank 1 is provided in a manner known per se with a cone 1 ′ for fastening in the tool spindle 2. The conical shank portion terminating in a tang 1 ", the 'drilling spindle 2 sits with play and has, inter alia, the task of the slot 2' Austreiberschlitz 2 to transfer the drill spindle 2, the torque on the tool shaft.

Um nun zu erreichen, daß ein abgebrochener Mitnehmerlappen 1" nicht durch den Austreiberschlitz 2' zwischen Bohrspindel und Schlitz 3' des Lagergehäuses 3 gelangt und so durch Blockieren der Bohrspindel zu Beschädigungen dieses Lagergehäuses bzw. der ganzen Maschine, darüber hinaus zu Verletzungen der Bedienenden führt, wird erfindungsgemäß der Schlitz 2' nach außen bei 2" so verengt, daß ein abgebrochener Mitnehmerlappen 1" nicht mehr nach außen in den Schlitz 3' des Gehäuses 3 gelangen kann.In order now to ensure that a broken off driver tab 1 ″ does not through the ejector slot 2 'between the drill spindle and slot 3' of the bearing housing 3 arrives and so by blocking the drilling spindle to damage this bearing housing or the entire machine, also leads to injuries to the operator, the slot 2 'is according to the invention narrowed outwards at 2 "so that a broken off Driving tabs 1 ″ can no longer pass outwards into the slot 3 ′ of the housing 3 can.

Der Schlitz 2' wird bei 2" nur so weit verengt, daß der zugeordnete Austreiberkeil noch Verwendung finden kann. Die Versperrung des Austreiberschlitzes kann auf verschiedene Art, durch einen Wulst oder durch Anbringen entsprechender Körper im bzw. am Austreiberschlitz der Bohrspindel z. B. durch eingesetzte Kugeln. oder Stifte erfolgen.The slot 2 'is narrowed at 2 "only so far that the assigned Expeller wedge can still be used. The blocking of the expeller slot can be done in various ways, by means of a bead or by attaching the appropriate Body in or on the ejector slot of the drill spindle z. B. by inserted balls. or pens.
