Die Neuerung geht von bekannten Mehrspinde 1 werkzeugköpfen, insbesondere Mehrspindelbohrkopfen aus, bei denen auf einem Gehäuse eine Vielzahl von Bohrspindeln vorgesehen sind. Das Gehäuse wird innerhalb einer Ebene auf eine Sollposition verfahren.Dann werden die nun gerade einzusetzende oder einzusetzenden Spindeln wenigstens um die Bearbeitungstiefe gegenüber den anderen Spindeln in Bohrrichtung vorgeschoben. Zum Bohrvorgang wird dann der das Gehäuse tragende schwere Support in Bearbeitungsrichtung bewegt.The innovation is based on known multi-spindle 1 tool heads, in particular multi-spindle drilling heads, in which a large number of drilling spindles are provided on a housing. The housing is moved to a target position within a plane. The spindles that are currently being used or are to be used are then advanced in the drilling direction by at least the machining depth compared to the other spindles. The heavy support carrying the housing is then moved in the machining direction for the drilling process.
Dem gegenüber wird der Support bei der Neuerung nur in der einen Ebene verfahren und für das Einbringen der Bohrung (oder den sonstigen Bearbeitungsvorgang) werden nur die leichten Werkzeugspindeln verschoben. Damit lassen sich genauere Bohrungen erzielen. Weitere Ausbildungen der Neuerung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.In contrast, the support in the new design is only moved in one plane and only the light tool spindles are moved to create the hole (or other machining operations). This allows more precise holes to be made. Further developments of the new design can be found in the subclaims and the drawing description.
Anhand der Zeichnung wird ein Ausführungsbeispiel der Erfindung beschr ieben.An embodiment of the invention is described with reference to the drawing.
Fig 1 zeigt einen Schnitt durch ein Bohrkopfgehäuse 13. Auf dem Gehäuse ist eine Hülse 12 mittels zweier Kugellager 14 drehbar gelagert. Mit der Hülse ist eine Zahnriemenscheibe 11 verbunden; ein nicht gezeigter Zahnriemen treibt die Hülse 12 an. Mittels Gleitlager ist in der Hülse 12 eine Bohrspindel 10 in Achsrichtung verschiebbar gelagert. Die Bohrspindel 10 trägt ein Spannfutter und einen Bohrer 18. Die Hülse 12 weist eine ausgedehnte Nut 16 auf. An der Bohrspindel 10 ist eine Passfeder 15 befestigt, die in die Nut 16 paßt und bewirkt, daß Spindel und Hülse drehfest miteinander verbunden sind, jedoch die Spindel in der Hülse verschiebbar ist.Fig. 1 shows a section through a drill head housing 13. A sleeve 12 is rotatably mounted on the housing by means of two ball bearings 14. A toothed belt pulley 11 is connected to the sleeve; a toothed belt (not shown) drives the sleeve 12. A drill spindle 10 is mounted in the sleeve 12 so that it can be displaced in the axial direction by means of a plain bearing. The drill spindle 10 carries a chuck and a drill 18. The sleeve 12 has an extended groove 16. A key 15 is attached to the drill spindle 10, which fits into the groove 16 and ensures that the spindle and sleeve are connected to one another in a rotationally fixed manner, but the spindle can be displaced in the sleeve.
Die Bohrspindel 10 ist mittels eines Kugellagers 9 auch drehbar an einem Verbindungsteil 7 gelagert. Dieses führt die Spindel (ist Mitnehmer) und nimmt den Bohrdruck auf.Zur Führung des Verbindungsteils 7 ist eine Führungsachse 5 mit dem Verbindungsteil 7 verbunden. Dieses ist in Gleitlagern 8 im Gehäuse 13 längsverschieblich gelagert, sodaß das Verbindungsteil 7 samt der Führungsachse 5 zusammen mit der Bohrspindel relativ zum Gehäuse 13 verschiebbar sind.The drilling spindle 10 is also rotatably mounted on a connecting part 7 by means of a ball bearing 9. This guides the spindle (is a driver) and absorbs the drilling pressure. To guide the connecting part 7, a guide axis 5 is connected to the connecting part 7. This is mounted in sliding bearings 8 in the housing 13 so that the connecting part 7 together with the guide axis 5 can be moved together with the drilling spindle relative to the housing 13.
Die Verschiebbarkeit wird durch eine am Gehäuse 13 drehbar gelagerte Gewindespindel 4 und eine mit dieser zusammenarbeitenden Gewindemutter 3 bewirkt, wenn die Gewindespindel angetrieben wird. Der Antrieb erfolgt überVZahnriemenscheiben 1 und über eine Kupplung 2, durch die die Gewindespindel an den immer laufenden Antrieb 1 zeitweise ankoppelbar ist. Der bei Ankupplung erzielte Vortrieb der Bohrspindel wird durch einen aus einem Zahnrad 19 und einem Geber 20 bestehenden Drehgeber kontrolliert und mittels eines Steuergeräts wird gemäß einer Vorgabe gesteuert gebohrt.The ability to move is achieved by a threaded spindle 4 that is rotatably mounted on the housing 13 and a threaded nut 3 that works with it when the threaded spindle is driven. The drive is via toothed belt pulleys 1 and a coupling 2, by means of which the threaded spindle can be temporarily coupled to the constantly running drive 1. The propulsion of the drilling spindle achieved when coupled is controlled by a rotary encoder consisting of a gear 19 and a sensor 20, and drilling is controlled according to a specification using a control device.
