Description
Die Erfindung betrifft eine hydrostatische Linearführung eines Schlittens am Maschinenbett eines Großbearbeitungszentrums zur qualitätsgerechten spanenden Bearbeitung von großen Werkstücken.The The invention relates to a hydrostatic linear guide of a Sleigh on the machine bed of a large machining center for the quality-oriented machining of large Workpieces.
Aus
dem Stand der Technik sind bereits Führungen von Schlitten
unterschiedlicher technischer Funktionalität bekannt, die
die Arbeitsgenauigkeit und das Leistungsvermögen einer
Werkzeugmaschine verbessern. So werden Eigenschaften, wie eine geringe
Reibung und eine stick-slip freie Bewegung des Schlittens auf den
Führungsschienen zur exakten Positionierung mit geringen
Verstellkräften und guter Dämpfung, ein geringer
Verschleiß der Führungsschienen zur Gewährleistung
der Arbeitsgenauigkeit sowie eine hohe Steifigkeit und Spielfreiheit
mit geringen Lageänderungen bei Belastung gefordert. Diese
Führungen sind nach ihrer technischen Funktionalität
vorrangig in werkstoffabhängige Linearführungen,
hybridische Führungsmechanismen und hydrostatische Linearführungen
einzuordnen. Für die werkstoffabhängigen Linearführungen
ist kennzeichnend, dass die Führungsbahnen einen schwingungsdämpfenden
und/oder verschleißfesten Gleitbelag mit teilweise auch
oberflächenstrukturiertem Aufbau für das Schmiermittel
aufweisen, wobei der Gleitbelag z. B. aus einem kalthärtenden
Epoxidharz (
Die
Aufgabe der Erfindung besteht deshalb darin, eine hydrostatische
Linearführung eines Schlittens am Maschinenbett eines Großbearbeitungszentrums
vorzuschlagen, die mit einem geringen anlagentechnischen und materiellen
Aufwand bei Umge bungstemperaturen von minus 5 Grad Celsius bis plus
40 Grad Celsius funktionssicher arbeitet und so eine qualitätsgerechte
spanende Bearbeitung von großen Werkstücken garantiert.
Erreicht wird dies durch die Merkmale des Schutzanspruchs. Die Vorteile
der Erfindung bestehen darin, dass durch den Einsatz von viskositätsabhängigen
Stromregelventilen für die hydrostatische Linearführung
das aufwendige Ölversorgungssystem „eine Pumpe
für jede Lagerasche" entfällt, damit der steuerungstechnische Aufwand
und der Platzbedarf geringer sind und die Betriebssicherheit des
Großbearbeitungszentrums durch eine ständige elektrotechnische Überwachung der
hydraulischen Linearführung verbessert wird. Die Erfindung
soll an einem Ausführungsbeispiel näher erläutert
werden. Hierzu zeigt die zugehörige Zeichnung die hydrostatische
Linearführung eines Schlittens am Maschinenbett eines Großbearbeitungszentrums
in der Seitenansicht im Schnitt mit einer schematischen Darstellung
des Ölversorgungssystems. Erkennbar ist, dass zwei Stütz-/Führungsflächen
