Description
Gegenstand der Erfindung ist ein verstellbarer Bohrkopf bei dem schwenkbare Messerträger oder Messer an Kurven geführt sind, deren Drehung um die Achse des Bohrkopfes die Verstellung der Messer bewirkt.The subject of the invention is an adjustable drill head with the pivotable knife carrier or knives are guided on curves, their rotation around the axis of the drill head the adjustment of the knife causes.
Das Neue der Erfindung besteht darin, daß der Träger der Führungskurve für jedes Messer auf einem exzentrischen Ansatz, des Hauptkörpers derart drehbar ist, daß sich bei der Verstellung die Exzentrizitäten der Führungskurve und des Ansatzes addieren.The novelty of the invention is that the carrier of the guide curve for each Knife on an eccentric attachment, the main body is rotatable in such a way that at add the eccentricities of the guide curve and the approach to the adjustment.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Auf einer Bohrwelle 1 sitzt ein auf beiden Seiten exzentrisch ausgebildeter Hauptkörper 2. Dieser Hauptkörper trägt auf jeder Seite ein mit Führungszapfen 6 versehenes Segment 3, in denen die Messer 4 befestigt sind. Die Segmente sind durch die Führungskurven 7 in den exzentrisch gelagerao ten, exzentrisch ausgebildeten Kurvenscheiben S an den Zapfen 6 im Durchmesser verstellbar. Die Kurvenscheiben werden durch Ritzel 8 und Zahnkranz 9 verstellt. Die Federn ι ο bringen die Zapfen 6 auf der Füha5 rungskurve 7 stets zur Anlage. Nach EinsteHung der Kurvensclieiben werden durch. Anziehen der Muttern. 11 die Preßscheiben 12 gegen die Kurvenscheiben und diese gegen die Segmente gedruckt. Die Segmente werden nach auf den Preßscheiben befindlichen Skalen 13 eingestellt.An exemplary embodiment is shown in the drawing. Sitting on a drilling shaft 1 a main body 2 eccentrically formed on both sides. This main body carries on each side a segment 3 provided with a guide pin 6, in which the knife 4 is attached are. The segments are eccentrically gelagerao through the guide curves 7 th, eccentrically designed cams S on the pin 6 adjustable in diameter. The cams are adjusted by pinion 8 and ring gear 9. The springs ι ο bring the pin 6 on the Füha5 curve 7 always to the plant. Once the curve closes are through. Tightening the nuts. 11 the press disks 12 printed against the cams and these against the segments. The segments are according to the scales 13 located on the press disks.
