in X-Richtung verfahrbaren Gantry, einer auf der Gantry in Y-Richtung verfahrbaren Traverse und einer von er Traverse in Z-Richtung verfahrbar gehaltenen Pinole.Gantry that can be moved in the X direction, a traverse that can be moved on the gantry in the Y direction and a spindle held by the traverse that can be moved in the Z direction.
Bei derart ausgebildeten BearbeitungsZentren ist es möglich, das Werkstück innerhalb eines umschriebenen Raumes, dessen Volumen viele Kubikmeter beinhalten kann, mit einem Werkzeug von den verschiedenen Seiten aus zu erreichen.With machining centers designed in this way, it is possible to reach the workpiece from different sides with one tool within a defined space, the volume of which can include many cubic meters.
Das Problem bei derartigen großen Bearbeitungszentren besteht darin, daß aufgrund der großen zu bewegenden Massen die erreichbare Geschwindigkeit nicht ausreichend ist. Der Versuch, die Massen zu verringern, scheiterte bisher daran, daß dann eine ausreichende Steifigkeit und Schwingungsresistenz nicht erreichbar war.The problem with such large machining centers is that the achievable speed is not sufficient due to the large masses that have to be moved. Attempts to reduce the masses have so far failed because sufficient rigidity and vibration resistance could not be achieved.
Der Erfindung liegt die Aufgabe zugrunde, ein Bearbeitungszentrum der eingangs genannten Art zu schaffen, das bei einer Verringerung der bewegten Massen hochsteif ist und schwingungsfrei arbeitet.The invention is based on the object of creating a machining center of the type mentioned at the beginning, which is highly rigid and operates without vibration while reducing the moving masses.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Gantry als ein vorgespanntes Leichtbau-Strebengerüst ausgerichtet ist, das vorzugsweise über Leichtmetall-Muffen miteinander verbundene Kohlefaserrohre gebildet wird.According to the invention, this object is achieved in that the gantry is designed as a prestressed lightweight strut framework, which is preferably formed by carbon fiber tubes connected to one another via light metal sleeves.
Eine weitere Verringerung der bewegten Massen können dadurch erreicht werden, daß die Traverse aus einem Honey-comb-Sandwich-Material gefertigt ist.A further reduction in the moving masses can be achieved by manufacturing the traverse from a honeycomb sandwich material.
Die Erfindung wird anhand einer Zeichnung erläutert. Dabei zeigt:The invention is explained using a drawing. It shows:
Fig. 1 eine Seitenansicht auf ein derartiges Bearbeitungszentrum, undFig. 1 is a side view of such a machining center, and
Fig. 2 eine Draufsicht auf ein derartiges Bearbeitungszentrum. Fig. 2 is a plan view of such a machining center.
Das Bearbeitungszentrum besteht aus einer Mehrzahl von in zwei Reihen aufgestellten Ständern 10 und einem Paar von auf den Ständern 10 ruhenden Linerf ührungen 12. Auf den Linearführungen 12 ist eine X-Richtung verfahrbare Gantry angeordnet. Auf der Gantry 14 wiederum ist eine Traverse 16 in Y-Richtung verfahrbar angeordnet. Die Traverse 16 hält eine in Z-Richtung verfahrbare Pinole 18.The machining center consists of a plurality of columns 10 arranged in two rows and a pair of linear guides 12 resting on the columns 10. A gantry that can be moved in the X direction is arranged on the linear guides 12. A traverse 16 that can be moved in the Y direction is arranged on the gantry 14. The traverse 16 holds a sleeve 18 that can be moved in the Z direction.
Die Figuren machen deutlich, daß die Gantry I^ als ein Leichtbau-Strebengerüst ausgebildet ist. Dabei besteht das Leichtbau-Strebengerüst aus Kohlefaserrohren 20, die über Leichtmetall-Muffen 18 miteinander vorgespannt verbunden sind.The figures make it clear that the gantry I^ is designed as a lightweight strut frame. The lightweight strut frame consists of carbon fiber tubes 20, which are prestressed and connected to one another via light metal sleeves 18.
Die bei der Ausbildung der Gantry als vorgespanntes Leichtbau-Strebengerüst erreichte Steifigkeit entspricht derjenigen, die bisher durch die Verwendung von massiven und schweren Bauelementen erreicht wird. Es hat sich weiter gezeigt, daß jedwede Schwingung einer derart ausgebildeten Gantry vermieden werden kann.The rigidity achieved by designing the gantry as a prestressed lightweight strut structure corresponds to that previously achieved by using massive and heavy structural elements. It has also been shown that any vibration of a gantry designed in this way can be avoided.
Bei einem bevorzugten Ausführungsbeispiel ist die Traverse aus einem leichten Honey-coinb-Sandwich-Material gefertigt, also einem Material, das bei einem sehr geringen Gewicht eine Festigkeit erreicht, das derjenigen eines metallischen Materials nicht nachsteht.In a preferred embodiment, the cross member is made of a lightweight honeycomb sandwich material, i.e. a material that achieves a strength that is not inferior to that of a metallic material at a very low weight.
Durch die Verwendung derartig leichter Materialien sind die bewegte Masse um viele Größenordnungen geringer als bei den bekannten Bearbeitungs&zgr;entren. Die erreichtbaren Bearbeitungsgeschwindigkeiten sind damit um eine Größenordnung höher, der Energieverbrauch um entsprechende Größenordnungen geringer.By using such light materials, the mass moved is many orders of magnitude smaller than in the known processing centers. The achievable processing speeds are therefore an order of magnitude higher, and the energy consumption is correspondingly orders of magnitude lower.
