Description
Befestigung für Reibahlen, Bohrköpfe, Messerköpfe o. dgl. Der Erfindungsgegenstand betrifft eine Befestigung für Reibahlen, Bohrköpfe o. dgl. mit kegeligem Schaft, durch die das Werkzeug sowohl bei radialer als auch bei axialer Bewegung der Einspannhülse, mit dieser umverschiebbar verbunden ist. Dies wird dadurch erreicht, daß winklige, mit schräg zur Achsrichtung verlaufenden Anschlagflächen versehene Zacken am Kegelansatz sich gegen gleichartige Gegenzacken ,der Einspannhülse legen, deren Winkel dem der Zacken entgegengesetzt gerichtet ist. Erfindungsgemäß werden ferner die Zacken dreieckförmig ausgebildet.Attachment for reamers, drill heads, cutter heads or the like. The subject of the invention relates to a fastening for reamers, drill heads or the like with a tapered shaft, which allows the tool to move both radially and axially of the clamping sleeve, is connected to this relocatable. This is achieved in that angular, Serrations on the cone base with stop surfaces running obliquely to the axial direction lie against similar opposing prongs of the clamping sleeve, the angle of which corresponds to that of the Point is directed in the opposite direction. According to the invention, the prongs also become triangular educated.
Befestigungen für Bohrer, Fräser usw. sind bekannt, durch die der Werkzeugschaft in der Einspan.nhülse derart gehalten wird, daß das Werkzeug sowohl bei radialer als auch bei axialer Bewegung des Werkzeughalters mit der Einspannhülse nnversichiebbar verbunden ist. Bei .diesen bekannten Vorrichtungen kann jedoch das Werkzeug nur in einer Drehrichtung mitgenommen werden. j Bei ,der neuen Befestigung erfolgt Mitnahme in beiden Drehrichtungen. Die dreieckige Ausbildung der Zacken ermöglicht ein k-rafts:chlüssiges Nachspannen :der Befestigung. Für Reibahlen, .die beiderseits Schäfte haben, bietet sich dabei der große Vorteil, daß sowohl mit ziehendem Antrieb in der einen als auch mit drückendem Antrieb in der anderen Drehrichtung gerieben werden kann. Das Festspannen und Lösen des Werkzeuges ist einfach und leicht. Trotzdem ist die Befestigung und Führung der Reibahle genau zentrisch.Fasteners for drills, milling cutters, etc. are known through which the Tool shank is held in the Einspan.nhülse such that the tool both with radial as well as axial movement of the tool holder with the clamping sleeve is connected in an insurable manner. In the case of these known devices, however, this can Tool can only be taken in one direction of rotation. j With the new fastening takes place in both directions of rotation. The triangular shape of the prongs enables a k-rafts: conclusive retensioning: the fastening. For reamers, .the have shafts on both sides, there is the great advantage that both with pulling Drive in one direction of rotation as well as with a push drive in the other direction of rotation can be rubbed. Clamping and loosening the tool is simple and easy. Nevertheless, the fastening and guidance of the reamer is exactly centric.
Der Gegenstand der Erfindung ist auf der Zeichnung in. beispielsweiser Ausführung veranschaulicht. Es stellt dar: Fig. i eine einstellbare Reibahle, Fig. 2 das Stangenende im teilweisen Längsschnitt, Fig.3 das Stangenende in Vorderansicht. Die Reibahle i hat an beiden Enden einen kegelförmigen Schaft 7, der .an seinem größeren Durchmesser zwei Zacken 8 aufweist. Die aufzuschiebende Stange 2 hat Aussparungen 12 und eine zum Schaft 7 passende Bohrung io, an deren vorderem Ende Gegenzacken i i sitzen. Wenn die Reibahle an einer Stange befestigt werden soll, werden die Zacken 8 in Aussparungen 12 eingeführt. Durch leichtes Verdrehen gelangen die Zapfen 8 in die Gänge 13 und legen sich gegen die Gegenzacken i i und damit an die kegelige Wandung fest und genau an. Dabei ist es vollkommen gleichgültig, ob die Stange nach rechts oder nach links gedreht wird.The object of the invention is on the drawing in. For example Demonstrates execution. It shows: Fig. I an adjustable reamer, Fig. 2 the rod end in a partial longitudinal section, FIG. 3 the rod end in a front view. The reamer i has a conical shaft 7 at both ends, the .an his has two prongs 8 larger diameter. The push-on rod 2 has recesses 12 and a hole io matching the shaft 7, at the front end of which there are opposing teeth i sit i. If the reamer is to be attached to a rod, the Prongs 8 introduced into recesses 12. The pegs can be reached by turning them slightly 8 in the gears 13 and lie against the opposing prongs i i and thus against the conical Wall firmly and precisely. It is completely irrelevant whether the rod is after is rotated right or left.
