Abstract

The invention relates to a machine tool with a machine housing (8) and a machining unit (1), displaceable in several dimensions, on which a tool revolver (2), with a number of tools (3), is arranged, each of which may be brought into a working position (5), by means of a rotation of the tool revolver (2) about a revolver axis (4). The tool revolver (2) is provided with a pivot unit (6), for pivoting the tool revolver (2) about a pivot axis (7) which is oriented in a direction which is not parallel to the revolver axis (4).

Description

Werkzeugmaschinemachine tool
Die Erfindung betrifft eine Werkzeugmaschine mit einem Maschinengehäuse und einer mehrdimensional verfahrbaren Bearbeitungseinheit, auf der ein Werkzeugrevolver mit einer Mehrzahl von Werkzeugen angeordnet ist, von denen jeweils eines durch Drehung des Werkzeugrevolvers um eine Revolverachse in eine Arbeitsposition bringbar ist,The invention relates to a machine tool with a machine housing and a multi-dimensionally movable machining unit, on which a tool turret with a plurality of tools is arranged, one of which can be brought into a working position by rotating the tool turret about a turret axis.
Derartige Werkzeugmaschinen sind aus der Praxis bekannt, die verwendet werden, um Werkstücke möglichst flexibel mit unterschiedlichen Werkzeugen und an unterschiedlichen Stellen bearbeiten zu können. Allerdings ist durch die festgelegte Einspannung des Werkstücks und die vorgegebene Orientierung des Werkzeugs in der Arbeitsstation bei den bekannten Werkzeugmaschinen die mögliche Bearbeitung eingeschränkt, die im wesentlichen parallel zu den Achsen eines kartesischen oordinatenssyste s erfolgt entsprechend der mehrdimensionalen Verfahrbarkeit der Bearbeitungseinheit .Such machine tools are known from practice, which are used to be able to machine workpieces as flexibly as possible with different tools and at different locations. However, due to the fixed clamping of the workpiece and the predetermined orientation of the tool in the work station in the known machine tools, the possible machining is restricted, which takes place essentially parallel to the axes of a Cartesian coordinate system in accordance with the multi-dimensional movability of the machining unit.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Werkzeugmaschine der eingangs genannten Art so auszubilden, daß deren Flexibilität gesteigert ist.The invention is therefore based on the object of designing a machine tool of the type mentioned in the introduction in such a way that its flexibility is increased.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß dem Werkzeugrevolver eine Schwenkeinheit zugeordnet ist zum Verschwenken des Werkzeugrevolvers um eine nicht parallel zur Revolverachse orientierten Schwenkachse.This object is achieved according to the invention in that the tool turret is assigned a pivot unit for pivoting the tool turret by one Swivel axis oriented parallel to the turret axis.
Dadurch ist der Vorteil erreicht, daß die Drehachse des Werkzeugs in der Arbeitsposition auch so orientiert werden kann, daß ohne weiteres beispielsweise geneigt verlaufende Bohrungen in das Werkstück eingebracht werden können, oder allgemein die Bearbeitungsrichtung nicht parallel zu den durch die Bearbeitungseinheit vorgegebenen Verstellrichtungen liegen muß, sondern auch durch eine Superposition von Komponenten der Verstellrichtungen gebildet werden kann.This has the advantage that the axis of rotation of the tool in the working position can also be oriented such that, for example, inclined bores can easily be drilled into the workpiece, or generally the machining direction does not have to be parallel to the adjustment directions specified by the machining unit, but can also be formed by a superposition of components of the adjustment directions.
Zur Vereinfachung der Kontrolle der Bewegungsabläufe ist dabei vorgesehen, daß die Schwenkachse orthogonal zur Drehachse des Werkzeugs in der Arbeitsposition steht.To simplify the control of the movements, it is provided that the pivot axis is orthogonal to the axis of rotation of the tool in the working position.
Eine große und auch ausreichende Flexibilität ist erreicht, wenn die Drehachse des Werkzeugs in der Arbeitsposition horizontal orientiert ist und der Schwenkbereich der Schwenkeinheit +/- 90° beträgt.A great and sufficient flexibility is achieved if the axis of rotation of the tool is oriented horizontally in the working position and the swivel range of the swivel unit is +/- 90 °.
Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert; die einzige Figur zeigt die erfindungsgemäße Werkzeugmaschine in einer perspektivischen Darstellung.The invention is explained in more detail below using an exemplary embodiment shown in the drawing; the single figure shows the machine tool according to the invention in a perspective view.
In der Figur 1 ist von einer Werkzeugmaschine eine mehrdimensional verfahrbare Bearbeitungseinheit 1 gezeigt, auf der ein Werkzeugrevolver 2 mit einer Mehrzahl von Werkzeugen 3 angeordnet ist, von denen jeweils eines durch Drehung des Werkzeugrevolvers 2 um eine Revolverachse 4 in eine Arbeitsposition 5 bringbar ist, wobei dem Werkzeugrevolver 2 eine Schwenkeinheit 6 zugeordnet ist zum Verschwenken des Werkzeugrevolvers 2 um eine nicht parallel zur Revolverachse 4 orientierten Schwenkachse, gekennzeichnet durch den Pfeil 7, die bei dem in der Zeichnung dargestellten Ausführungsbeispiel orthogonal zur Drehachse des Werkzeugs 3 in der Arbeitsposition 5 steht. Die Drehachse des Werkzeugs 3 in der Arbeitsposition 5 ist horizontal orientiert und der Schwenkbereich der Schwenkeinheit 6 beträgt +/- 90°. 1 shows a multi-dimensionally movable processing unit 1 of a machine tool, on which a tool turret 2 with a plurality of tools 3 is arranged, one of which can be brought into a working position 5 by rotating the tool turret 2 about a turret axis 4, whereby a swivel unit 6 is assigned to the tool turret 2 for pivoting the tool turret 2 about a pivot axis which is not oriented parallel to the turret axis 4, characterized by the arrow 7, which in the embodiment shown in the drawing is orthogonal to the axis of rotation of the tool 3 in the working position 5. The axis of rotation of the tool 3 in the working position 5 is oriented horizontally and the swivel range of the swivel unit 6 is +/- 90 °.
