Abstract

In a machine tool, the supply unit for the supply of cooling product and/or lubricant comprises an automatic control (11) which enables to automatically change the position of a nozzle (4) by means of a stepping motor (9) so that the nozzle (4), independently of the position of the workpiece or of the tool, has permanently such an orientation that a jet of a cooling and/or lubricant product impacts against the cutting edge of the tool, respectively the contact area between the tool and the workpiece.

Description

Werkzeugmaschine Machine tool
Die Erfindung bezieht sich auf eine Werkzeugmaschine mit einer lilerkzeughalterung für ein Werkzeug und einer zumindest eine Spritzdüse aufweisenden Zuführeinrichtung für ein Mittel zum Kühlen und/oder Schmieren. Solche Werkzeug- maschinen sind allgemein bekannt.The invention relates to a machine tool with a lilerkzeughalterung for a tool and a supply device having at least one spray nozzle for a means for cooling and / or lubrication. Such machine tools are generally known.
Bei der spanabhebenden Bearbeitung von Werkstücken auf Werkzeugmaschinen ist es meist erforderlich, einen Kühl- und/oder Schmiermittelstrahl oder mehrere auf die Schneide des Werkzeugs zu richten, damit diese und eϊforderlichen- falls das Werkstück gekühlt, die Spanelemente geschmiert und die abgetrennten Späne fortgespült wird. Auch bei der spanlosen Bearbeitung dient die Zuführeinrichtung dazu, die Hontaktzone zwischen Werkzeug und Werkstück zu kühlen und zu schmieren. Das geschieht in der Regel mittels eines flexiblen Schlauches, der vom Bediener der Werkzeugmaschine von Hand auf das Werkzeug gerichtet werden muß. Leider ist es nicht damit getan, den Schlauch zu Beginn eines Zer- spanungsprozesses in die richtige Stellung zu bringen, vielmehr ist ein ständiges Nachrichten des Schlauches von Hand erforderlich, da sich die Lage des Werkzeugs oder des Werkstückes während des Arbeitsprozesses ständig ändert. Die Form eines Werkstückes kann zum Beispiel erforderlich machen, daß zu Beginn des Zerspanungsprozesses von einer Seite und später von der anderen Seite auf die Werkzeugschneide gespritzt wird. Abgesehen davon, daß dieses Nachrichten des Schlauches ständige Überwachung erforderlich macht, entsteht durch die Handbedienung eine erhebliche Unfallgefahr, weil der Maschinenbediener sich bei der geringsten Unaufmerksamkeit an dem scharfen, rotierenden Werkzeug verletzen kann. Zu bedenken ist auch, daß Werkzeugmaschinen meist auto- matisch gesteuert sind. Abgesehen von der automatischen Steuerung der Werkzeugbeuiegungen findet sehr häufig ein automatischer Werkzeugwechsel statt. Die Werkzeugmaschine und der Werkzeugwechsler führen dabei Bewegungen aus, die vom Maschinenbediener nicht vorhersehbar sind und ihn er- heblich gefährden können, wenn er sich in die Maschine beugt und mit der Hand den Schlauch verstellen will.When machining workpieces on machine tools, it is usually necessary to point a jet of coolant and / or lubricant at the cutting edge of the tool so that it and, if necessary, the workpiece is cooled, the chip elements are lubricated and the separated chips are washed away. The feed device also serves to cool and lubricate the honing zone between the tool and the workpiece during non-cutting machining. This is usually done by means of a flexible hose that must be directed by the operator of the machine tool onto the tool. Unfortunately, it is not enough to put the hose into the correct position at the beginning of a machining process. Rather, it is necessary to constantly report the hose by hand, since the position of the tool or the workpiece changes constantly during the work process. For example, the shape of a workpiece may require spraying onto the cutting edge from one side at the beginning of the machining process and later from the other side. In addition to the fact that this notification of the hose requires constant monitoring, the manual operation creates a considerable risk of accident because the machine operator can injure himself at the slightest inattention of the sharp, rotating tool. It should also be borne in mind that machine tools are usually controlled automatically. Apart from the automatic control of the tool flexion, an automatic tool change takes place very often. The machine tool and the tool changer perform movements that are not foreseeable by the machine operator and can pose a considerable risk if he bends into the machine and wants to adjust the hose by hand.
Um bei automatisch arbeitenden Werkzeugmaschinen auf eine Überwachung und manuelle Regulierung der Zufuhr des Mittels zum Mühlen und/oder Schmieren verzichten zu können, ist es auch schon bekannt, feststehende Düsen oder Düsenkränze vorzusehen, aus denen aus verschiedenen Richtungen Schneid- flüssigkeit auf das Werkzeug spritzt. Das Werkzeug arbeitet dann in einem Regen von Schneidflüssigkeit. Die Praxis hat jedoch gezeigt, daß auch bei einer solchen Zuführeinrichtung für Schneidflüssigkeit oftmals keine ausreichende Menge an Schneidflüssigkeit gegen die Werkzeugschneide spritzt, viel- mehr der größte Schneidflüssigkeitsanteil daneben geht. Dadurch wird die Werkzeugschneide unzureichend gekühlt und geschmiert, so daß die Standzeit des Werkzeugs sich verringert oder es sogar zu einem Werkzeugbruch und einer Beschädigung des Werkstückes kommt. Der Erfindung liegt die Aufgabe zugrunde, eine Werkzeug- maschine der eingangs genannnten Art derart auszubilden, daß auch hei automatischer Steuerung der Werkzeugmaschine . ohne Überwachung und Manipulation des Bedieners der Werkzeugmaschine stets ausreichend viel Kühl - und/oder Schmier- mittel die Werkzeugschneide bzw. Hontaktzone zwischen Werk stück und Werkzeug gelangt.In order to be able to dispense with monitoring and manual regulation of the supply of the means for milling and / or lubrication in automatic machine tools, it is also known to provide fixed nozzles or nozzle rings from which cutting fluid sprays onto the tool from different directions. The tool then works in a rain of cutting fluid. Practice has shown, however, that even with such a feed device for cutting fluid, a sufficient amount of cutting fluid often does not spray against the tool cutting edge, rather the largest proportion of cutting fluid goes wrong. As a result, the tool cutting edge is insufficiently cooled and lubricated, so that the service life of the tool is reduced or there is even tool breakage and damage to the workpiece. The object of the invention is to design a machine tool of the type mentioned at the outset in such a way that the machine tool is also controlled automatically. without monitoring and manipulation of the operator of the machine tool, sufficient coolant and / or lubricant always gets the tool cutting edge or honing zone between the workpiece and the tool.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zuführeinrichtung eine automatische Steuerung zur Steuerung des Kühl - und/oder Schmiermittelstrahls oder der Strahlen in Abhängigkeit von der Position der Werk- zeugschneide oder des Werkstücks hat.This object is achieved according to the invention in that the feed device has an automatic control for controlling the coolant and / or lubricant jet or the jets as a function of the position of the tool cutting edge or the workpiece.
Dank dieser erfindungsgemäßen automatischen Steuerung der Zuführeinrichtung für das Kühl und/oder Schmiermittel wird die Werkzeugmaschine erst zu einer voll automatisch arbeitenden Maschine, die auch längere Zeit ohne Überwachung und Eingreifen durch den Bediener arbeiten kann. Da dank der Erfindung eine ausreichende Kühlung und Schmierung des Werkzeugs unabhängig von der Sorgfalt des Bedieners sicher- gestellt ist, erhöht sich die Standzeit das Werkzeugs und die Bearbeitungsqualität des Werkstücks. Weiterhin ver- mindert sich die Unfallgefahr für den Bediener ganz erheblich, weil er nicht mehr zum Nachrichten des Strahls von Kühl - und/oder Schmiermittel in die laufende Maschine greifen muß. Durch die Erfindung wird es zudem möglich, die Werkzeugmaschine während ihres Arbeitens vollständig abzu- kapseln, so daß auch ein versehentliches Inberührungkommen mit laufenden Maschinenteilen ausgeschlossen ist.Thanks to this automatic control of the supply device for the coolant and / or lubricant according to the invention, the machine tool only becomes a fully automatic machine which can also work for a long time without monitoring and intervention by the operator. Since, thanks to the invention, sufficient cooling and lubrication of the tool is ensured independently of the care of the operator, the tool life and the machining quality of the workpiece are increased. Furthermore, the risk of accidents for the operator is reduced considerably because he no longer has to reach into the running machine to report the jet of coolant and / or lubricant. The invention also makes it possible to completely encapsulate the machine tool while it is working, so that accidental contact with running machine parts is also ruled out.
Denkbar wäre es, beim Programmieren der Steuerung einer Werkzeugmaschine zugleich die erforderlichen Bewegungen der Zuführeinrichtungen für das Kühl - und Schmiermittel mit zu programmieren. Einfacher ist es allerdings, wenn die automatischeIt would be conceivable to also program the necessary movements of the supply devices for the coolant and lubricant when programming the control of a machine tool. However, it is easier if the automatic
Steuerung gemäß einer vorteilhafter Ausgestaltung der Erfindung eine unabhängig von der Steuerung der Werkzeugmaschine zu programmierende Einheit ist. In einem solchen Fall kann eine automatisch arbeitende Werkzeug- maschine auch leicht nachträglich in die erfindungsge- mäße Werkzeugmaschine umgewandelt werden. Oftmals ge- nügt auch zur Steuerung der Zuführeinrichtung ein sehr einfaches Programm, weil nicht jede Werkstück- oder Werk- zeugbewegung eine Verstellung der Zuführeinrichtung er- forderlich macht.Control according to an advantageous embodiment of the invention is a unit to be programmed independently of the control of the machine tool. In such a case, an automatically working machine tool can also be easily converted into the machine tool according to the invention. A very simple program is often sufficient to control the feed device, because not every workpiece or tool movement requires an adjustment of the feed device.
Eine ganz besonders einfache automatische Steuerung er- hält man, wann diese zeitabhängig arbeitet. Der Bediener kann beim Bearbeiten des ersten einer Serie von Werkstücken die Zuführeinrichtung manuell steuern und die Steuerbewegung sowie die Zeitpunkte der Steuerbewegungen in einem Programmspeicher abspeichern, so daß bei den weiteren Werkstücken die Zuführeinrichtung automatisch arbeitet, sofern nur darauf geachtet wird, daß die Steuerung für die Zuführeinrichtung stets synchron zum Maschinenprogramm erfolgt.A particularly simple automatic control is obtained when it works time-dependent. When processing the first of a series of workpieces, the operator can manually control the feed device and store the control movement and the times of the control movements in a program memory, so that the feed device works automatically for the further workpieces, provided that only care is taken to ensure that the control for the Feeding device is always synchronized with the machine program.
Ganz besonders gering wird der bauliche Aufwand für die erfindungsgemäße Werkzeugmaschine, wenn die Zuführein- ridhtung mehrere Spritzdüsen hat, welche durch die automatische Steuerung wahlweise einschaltbar sind. Die Spritzdüsen können relativ weit vom Werkzeug angeordnet werden, da durch die automatische Steuerung jeweils gerade diejenige Spritzdüse angesteuert werden kann, durch die ein Strahl des Kühl - und/oder Schmiermittels aus- reichend genau zum Schneidwerkzeug bzw. zur Kontaktzone gelangt. In vielen Fällen kommt man schon mit einer einzigenThe structural outlay for the machine tool according to the invention becomes particularly low if the feed device has a plurality of spray nozzles which can be optionally switched on by the automatic control. The spray nozzles can be arranged relatively far from the tool, since the automatic control can control the spray nozzle through which a jet of the coolant and / or lubricant reaches the cutting tool or the contact zone with sufficient accuracy. In many cases, you can come with just one
Spritzdüse oder zwei Spritzdüsen aus, wenn die Zuführ- einrichtung zumindest eine Spritzdüse hat, welche mittels eines Motors durch die automatische Steuerung verstellbar ist. Durch die Uerstellmöglichkeit kann man auch bei größerem Abstand der Spritzdüse vom Werkzeug hinreichend genau gegen das Werkzeug spritzen, so daß die Spritzdüsen relativ weit außerhalb des Arbeitsbereiches der Werkzeug- maschine angeordnet werden können und dadurch das Arbeiten der Werkzeugmaschine nicht behindern, insbesondere auch dann nicht, wann die Maschine eine automatische Werkzeug- oder Werkstückwechseleinrichtung hat.Spray nozzle or two spray nozzles if the feed device has at least one spray nozzle which is adjustable by means of a motor by the automatic control. As a result of the possibility of adjustment, it is possible to spray sufficiently precisely against the tool even when the spray nozzle is at a greater distance from the tool, so that the spray nozzles can be arranged relatively far outside the working area of the machine tool and thus do not hinder the work of the machine tool, in particular not even then, when the machine has an automatic tool or workpiece changing device.
Die Zuführeinrichtung gestaltet sich besonders einfach, wenn die Spritzdüse radial an einem schwenkbaren Spritz- düsenkopf vorgesehen ist, welcher zum Antrieb einen Motor hat. Denkbar ist es natürlich auch, die Spritzdüse in zwei Ebenen automatisch zu verstellen oder sogar auf einem Kreuz- schlitten verfahrbar anzuordnen.The feed device is particularly simple if the spray nozzle is provided radially on a pivotable spray nozzle head which has a motor for driving. It is of course also conceivable to automatically adjust the spray nozzle in two levels or even to arrange it on a cross slide.
Eine andere vorteilhafte Möglichkeit der Steuerung des Strahls besteht darin, daß eine Spritzdüse vorgesehen wird, deren Querschnitt durch die automatische Steuerung veränderbar ist. Bei dieser Ausgestaltung kann man beispielsweise durch Ver- kleinerung des Düsenquerschnittes erreichen, daß diese weiter spritzt als mit einem größeren Querschnitt. Deshalb ist auch auf diese Weise eine Regulierung der Auftreffstelle des Strahls möglich.Another advantageous possibility of controlling the jet is to provide a spray nozzle whose cross section can be changed by the automatic control. In this embodiment, it can be achieved, for example, by reducing the nozzle cross-section that it injects more than with a larger cross-section. It is therefore also possible to regulate the point of impact of the beam in this way.
Die Erfindung läßt zahlreiche Ausführungsmöglichkeiten zu. Zur Verdeutlichung ihres Grundprinzips ist in der Zeichnung schematisch eine Zuführeinrichtung für Kühl - und/oder Schmiermittel dargestellt und wird nachfolgend beschrieben.The invention allows numerous design options. To illustrate their basic principle is in the Drawing schematically shows a supply device for coolants and / or lubricants and is described below.
Die Zeichnung zeigt eine U-förmige Konsole 1, die um eine Welle 2 schwenkbar einen Spritzdüsenkopf 3 lagert. Am Spritzdüsenkopf 3 ist eine Spritzdüse 4 angebracht. Schneidflüssigkeit strömt bei Betrieb der Zuführein- richtung von einem Anschluß 5 der Konsole 1 durch eine Leitung 6 in einen Ringraum 7, von dort durch Löcher 8 in das Innere der Achse 2 und anschließend durch denThe drawing shows a U-shaped bracket 1, which supports a spray nozzle head 3 pivotably about a shaft 2. A spray nozzle 4 is attached to the spray nozzle head 3. Cutting fluid flows during operation of the feed device from a connection 5 of the console 1 through a line 6 into an annular space 7, from there through holes 8 into the interior of the axis 2 and then through the
Spritzdüsenkopf 3 und die Spritzdüse 4. Je nach Stellung des Spritzdüsenkopfes 3 spritzt Schneidflüssigkeit mehr oder minder weit aus der Sppitzdüse 4. Zum Verstellen des Spritzdüsenkopfes 3 dient ein Motor 9, der über eine Kupplung 10 die Welle 2 des Spritz- düsenkopfes 3 antreibt. Zur Steuerung des Motors 9 dient eine automatische Steuerung 11, durch die je nach Steuer- Programm der Motor 9 veranlaßt wird, den Spritzdüsenkopf 3 um einen bestimmten Winkelbetrag zu verdrehen. Spray nozzle head 3 and the spray nozzle 4. Depending on the position of the spray nozzle head 3, cutting fluid sprays more or less far out of the spray nozzle 4. A motor 9, which drives the shaft 2 of the spray nozzle head 3 via a coupling 10, is used to adjust the spray nozzle head 3. An automatic control 11 is used to control the motor 9, by means of which, depending on the control program, the motor 9 is caused to rotate the spray nozzle head 3 by a certain angular amount.
