Abstract
Description
Die Erfindung betrifft eine Werkzeugmaschine zum Bearbeiten von Werkstücken in einem Bearbeitungsraum.The invention relates to a machine tool for machining workpieces in a processing room.
Eine derartige Werkzeugmaschine nach
der Gantry-Bauart ist z. B. aus der
Gemäß der
Um die Auswirkungen von Temperaturänderungen auf die Einstellwerte möglichst gering zu halten, sind die Bauteile in der Regel aus Stahl hergestellt. Dennoch ist eine numerische Kompensation der Einstellwerte der verschiedenen Achsen aufgrund der thermischen Ausdehnung der einzelnen Bauteile über eine entsprechende Steuereinrichtung erforderlich.To the effects of temperature changes to the setting values if possible to keep it low, the components are usually made of steel. Nevertheless, a numerical compensation of the setting values of the various Axes due to the thermal expansion of the individual components over a appropriate control device required.
Der Erfindung liegt die Aufgabe zu Grunde, eine schnelle und sicher einstellbare, mit geringen Kosten und geringem Aufwand herstellbare Werkzeugmaschine zu schaffen.The invention is based on the object Basically, a quick and safely adjustable, with low cost and to create machine tool that can be produced with little effort.
Diese Aufgabe wird durch eine Werkzeugmaschine nach Anspruch 1 gelöst. Die Unteransprüche beschreiben bevorzugte Weiterbildungen.This task is done by a machine tool solved according to claim 1. The subclaims describe preferred further training.
Der Erfindung liegt der Gedanke zu Grunde, anstelle der aufwändigen numerischen Kompensation der temperaturbedingten Längenänderungen die Temperatur im Betrieb möglichst konstant zu halten. Erfindungsgemäß wird hierdurch eine überraschend kostengünstig und mit geringem Aufwand herstellbare Lösung geschaffen, indem der Spindelkörper auf seiner Außenseite gekühlt wird. Dem liegt die Erkenntnis zu Grunde, dass die zu relevanten Längenänderungen führende Wärmeentwicklung von dem Spindelkörper ausgeht und dementsprechend durch eine geeignete Kompensation direkt an der wesentlichen Wärmequelle die aufwendige numerische Kompensationen der Einstellwerte entfallen kann.The idea lies with the invention Basically, instead of the elaborate one numerical compensation of the temperature-related changes in length the temperature in operation as possible to keep constant. According to the invention, this is a surprisingly inexpensive and Solution created with little effort by the spindle body on its outside chilled becomes. This is based on the knowledge that the too relevant changes in length premier heat generation from the spindle body goes out and accordingly directly by a suitable compensation at the essential heat source there is no need for complex numerical compensation of the setting values can.
Eine besonders vorteilhafte erfindungsgemäße Kombination ergibt sich bei der zusätzlichen Verwendung von Linearantrieben bzw. Direktantrieben zur Verstellung des auf den Längsschienen geführten Transportschlittens und des auf den Querschienen des Transportschlittens geführten Bearbeitungsschlittens, da die Linearantriebe bzw. Direktantriebe keine nennenswerte Wärmeentwicklung aufweisen und somit keine nennenswerte und dauerhafte Erwärmung dieser Bauteile der Längs- und Querverstellung auftritt, so dass sämtliche Achsen ohne Kompensation angesteuert werden können.A particularly advantageous combination according to the invention results from the additional use of linear drives or direct drives to adjust the the longitudinal rails out Transport carriage and the on the cross rails of the transport carriage out Processing slide, because the linear drives or direct drives no significant heat development have and therefore no significant and permanent heating of these Components of the longitudinal and cross adjustment occurs so that all axes without compensation can be controlled.
Indem nun durch die erfindungsgemäße Kühlung auf der Außenseite des Spindelkörpers eine gleichbleibende Temperatur erreicht wird, kann als Material für den Spindelkörper und vorteilhafterweise auch die weiteren zu verstellenden Elemente ein Leichtmetall gewählt werden, insbesondere Aluminium. Hierdurch ergibt sich eine weitere vorteilhafte Kombination mit einem hohen Synergieeffekt, da die Direktantriebe nur noch geringe Massen verstellen müssen, so dass eine sehr schnelle Verstellung möglich ist, bei der entsprechend auch eine zu vernachlässigende Wärmeentwicklung auftritt.Now by the cooling according to the invention the outside of the spindle body A constant temperature can be reached as a material for the spindle body and advantageously also the other elements to be adjusted selected a light metal be, especially aluminum. This results in another one advantageous combination with a high synergy effect, because the direct drives only need to adjust small masses, so that a very fast Adjustment possible is, in which there is also negligible heat development.
Die erfindungsgemäße Werkzeugmaschine ist somit überraschend einfach aufgebaut, erfordert keine numerische Kompensation der Einstellwerte und vermag auf Grund der schnellen und genauen Verstellbarkeit und Positionierbarkeit der Spindel eine schnelle Bearbeitung zu ermöglichen.The machine tool according to the invention is therefore surprising simply constructed, does not require numerical compensation of the setting values and due to the quick and precise adjustability and positionability to enable the spindle to be processed quickly.
Die Kühleinrichtung kann insbesondere als schraubenförmiges Gewinde auf der Außenseite des Spindelkörpers ausgebildet sein. Eine Abdichtung des z. B. gefrästen schraubenförmigen Kühlkanals bzw. der mehreren Kühlkanäle nach außen kann insbesondere direkt durch die Innenfläche der umgebenden Spindelkörperaufnahme erfolgen.The cooling device can in particular as a helical Thread on the outside of the spindle body be trained. A seal of the z. B. milled helical cooling channel or of the several cooling channels Outside can in particular directly through the inner surface of the surrounding spindle body receptacle respectively.
