Description

VERFAHREN UND VORRICHTUNG ZUR FERTIGUNG METHOD AND DEVICE FOR PRODUCTION
VON WERKSTÜCKENOF WORKPIECES
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Fertigung von Werkstücken, insbesondere zur Komplettfertigung komplexer Werkteile .The invention relates to a method and a device for the production of workpieces, in particular for the complete production of complex workpieces.
Zur Herstellung von Werkstücken, insbesondere von Werkstücken mit aufeinanderfolgenden unterschiedlichen Bearbeitungsschritten, ist es bisher notwendig, die Werkstücke für die einzelnen Bearbeitungsschritte umzuspannen oder gegebenen- falls auf eine weitere Werkzeugmaschine zu bringen, was den Arbeitsaufwand erhöht und der Präzision abträglich ist.For the production of workpieces, in particular workpieces with successive different machining steps, it has hitherto been necessary to reclamp the workpieces for the individual machining steps or, if necessary, to bring them to another machine tool, which increases the workload and detracts from precision.
Es ist zur Herstellung komplexer Werkteile, das sind aus mehreren Teilen zusammengesetzte Baugruppen, bekannt die Aus- gangsteile dieser Werkteile durch Urformen oder Umformen aus einem Ausgangsmaterial zu formen, um dann über die Verfahrensschritte des Trennens, Fügens, Beschichtens und des Vorganges der Stoffeigenschaftsänderung den Endzustand und die hierfür erforderlichen Stoffeigenschaften herzustellen. Dabei werden für j eden dieser Verfahrensschritte spezielle Vorrichtungen in Form von Werkzeugmaschinen verwendet. Die Verkettung der Arbeitsvorgänge auf den einzelnen Maschinen erfolgt hierbei manuell oder automatisch . Im Falle der manuellen Verknüpfung ist der Arbeitsaufwand beträchtlich und im Falle der automatischen Verkettung sind häufig Fertigungsstraßen mit erheblichem Platzbedarf erforderlich . Aufgabe der Erfindung ist es, eine Fertigung von Werkstücken und eine Komplettfertigung komplexer Werkteile sowohl hinsichtlich des Arbeitsaufwandes als auch hinsichtlich des Platzbedarfes der einzusetzenden Maschinen zu vereinfachen.It is known for the production of complex work parts, that is, assemblies composed of several parts, to form the starting parts of these work parts by means of primary shaping or shaping from a starting material, in order to then use the process steps of separating, joining, coating and the process of changing the material properties to achieve the final state and to produce the required material properties. Special devices in the form of machine tools are used for each of these process steps. The process operations on the individual machines are linked manually or automatically. In the case of manual linking, the workload is considerable and in the case of automatic linking, production lines with considerable space requirements are often required. The object of the invention is to simplify the manufacture of workpieces and the complete manufacture of complex workpieces both in terms of the amount of work involved and in terms of the space required for the machines to be used.
Diese Aufgabe wird bei einem Verfahren zur Fertigung von Werkstücken erfindungsgemäß dadurch gelöst, dass verschiedene Bearbeitungseinrichtungen im Funktionsbereich minde- stens einer multifunktionalen Werkzeugmaschine einsetzbar sind und die zu fertigenden Werkstücke mittels einer Maschineneinheit mit schwenkbarer und nach dem pick-up-Prinzip arbeitenden Arbeitsspindel der Werkzeugmaschine in die für die Bearbeitung günstigste Lage gebracht werden.In a method for manufacturing workpieces, this object is achieved according to the invention in that different machining devices can be used in the functional area of at least one multifunctional machine tool and the workpieces to be manufactured by means of a machine unit with a pivoting work spindle of the machine tool working according to the pick-up principle the most convenient location for processing.
Hinsichtlich eines Verfahrens zur Komplettfertigung komplexer Werkteile wird die Aufgabe erfindungsgemäß dadurch gelöst, dass verschiedene Bearbeitungseinrichtungen im Funktionsbereich mindestens einer multifunktionalen Werkzeugmaschine einsetzbar sind und die aus mindestens zwei Werkstücken zu fertigenden Werkteile mittels einer Maschineneinheit mit schwenkbarer und nach dem pick-up-Prinzip arbeitenden Arbeitsspindel der Werkzeugmaschine in die für die jeweilige Bearbeitung günstigste Lage gebracht werden.With regard to a method for the complete production of complex workpieces, the object is achieved according to the invention in that different machining devices can be used in the functional area of at least one multifunctional machine tool and the workpieces to be manufactured from at least two workpieces by means of a machine unit with a pivoting work spindle which works according to the pick-up principle Machine tool can be brought into the most favorable position for the respective processing.
Dabei ist eine multifunktionale Werkzeugmaschine eine Maschine , bei der aufgrund der beschriebenen Eigenschaften, nämlich die Arbeitsmöglichkeit nach dem pick-up-Prinzip und die schwenkbare Anordnung der Arbeitsspindel, ein Werkstück oder auch ein bereits zusammengesetztes Werkteil den unterschiedlichsten Bearbeitungsvorgängen in den verschiedensten Positionen unterworfen werden können. Durch die Verwendung einer solchen multifunktionalen Werkzeugmaschine ist es möglich das zu bearbeitende Teil in die für die jeweilige Bear- beitung günstigste Lage zu bringen. Dies ist deshalb besonders vorteilhaft, weil hierdurch die Bearbeitungseinrichtungen einfach gestaltet werden können und auch in einfacher Weise in dem Funktionsbereich dieser Werkzeugmaschine einsetzbar sind, was sowohl die stationäre Anordnung solcher Bearbei- tungseinrichtungen in dem Funktionsbereich der Werkzeugmaschine als auch den verfahrbaren Einsatz solcher Bearbeitungseinrichtungen umfasst. Ebenso ist es möglich, den Arbeitsablauf günstiger zu gestalten.A multifunctional machine tool is a machine in which, due to the properties described, namely the possibility of working according to the pick-up principle and the swiveling arrangement of the work spindle, a workpiece or an already assembled workpiece can be subjected to a wide variety of machining processes in a wide variety of positions , By using such a multifunctional machine tool, it is possible to bring the part to be machined into the most favorable position for the respective machining. This is why it is special This is advantageous because the machining devices can be designed in a simple manner and can also be used in a simple manner in the functional area of this machine tool, which includes both the stationary arrangement of such machining devices in the functional area of the machine tool and the movable use of such machining devices. It is also possible to make the workflow cheaper.
Eine Vorrichtung zur Fertigung von Werkstücken, insbesondere solcher bei denen mehrere aufeinanderfolgende Arbeitsschritte erforderlich sind oder zur Komplettfertigung komplexer Werkteile , die insbesondere zur Durchführung der oben erläuterten Verfahren dienen kann, ist erfindungsgemäß da- durch gekennzeichnet, dass sie mindestens eine multifunktionale Werkzeugmaschine mit einer Maschineneinheit umfassend eine Arbeitsspindel, die in einem schwenkbar gelagerten Träger zur Durchführung des pick-up-Prinzips in Spindelachsrichtung verschiebbar gehalten ist, aufweist, dass die Maschineneinheit über einem Transportsystem für die Werkteile bzw. Werkstücke und Bearbeitungseinrichtungen für die Werkstücke angeordnet ist und dass die Bearbeitungseinrichtungen in dem Funktionsbereich der Arbeitsspindel einsetzbar ausgebildet sind.A device for the production of workpieces, in particular those in which several successive work steps are required or for the complete production of complex workpieces, which can be used in particular to carry out the methods explained above, is characterized according to the invention in that it comprises at least one multifunctional machine tool with a machine unit A work spindle, which is held in a pivotably mounted carrier for carrying out the pick-up principle in the spindle axis direction, has that the machine unit is arranged above a transport system for the workpieces or workpieces and processing devices for the workpieces and that the processing devices in the Functional area of the work spindle are designed to be used.
Dabei können die Arbeitseinrichtungen im Funktionsbereich der Werkzeugmaschine stationär angeordnet sein oder entsprechend einer anderen weiteren Ausgestaltung können die Bearbeitungseinrichtungen in den Funktionsbereich der Werkzeugmaschine hineinfahrbar ausgebildet sein.In this case, the working devices can be arranged in a stationary manner in the functional area of the machine tool or, according to another further embodiment, the machining devices can be designed to be movable into the functional area of the machine tool.
Nach einer weiteren Ausgestaltung der Erfindung ist jede Maschineneinheit quer zur Schwenkachse des Trägers für die Arbeitsspindel in horizontaler Richtung verfahrbar. Diese Ausgestaltung erweitert die Anwendungsmöglichkeit der Werkzeug- maschine in beträchtlichem Maße, wobei dieser Vorteil sich bei der Ausführungsvariante mit den in den Funktionsbereich der Werkzeugmaschine hineinfahrbaren Bearbeitungseinrichtungen noch stärker auswirkt.According to a further embodiment of the invention, each machine unit can be moved in the horizontal direction transversely to the pivot axis of the carrier for the work spindle. This configuration extends the application possibilities of the machine tool to a considerable extent, this advantage being evident in the embodiment variant with the machining devices that can be moved into the functional area of the machine tool has an even greater impact.
Eine platzsparende Ausgestaltung der Werkzeugmaschine ergibt sich dadurch, dass die Arbeitsspindel als Motorspindel ausgebildet ist.A space-saving design of the machine tool results from the fact that the work spindle is designed as a motor spindle.
Besonders vorteilhaft ist eine weitere Ausgestaltung der Erfin- düng, die darin besteht, dass der schwenkbar gelagerte Träger für die Arbeitsspindel kurbelwellenartig ausgebildet ist. Diese Ausgestaltung ist dann besonders vorteilhaft, wenn sich der Kurbelteil in der Vertikalstellung der Arbeitsspindel oberhalb des Lagerteiles des Trägers befindet, weil dann ein besonders hoher Arbeitsraum unterhalb der Arbeitsspindel zur Verfügung steht.A further embodiment of the invention is particularly advantageous, which consists in that the pivotably mounted carrier for the work spindle is designed like a crankshaft. This configuration is particularly advantageous when the crank part is in the vertical position of the work spindle above the bearing part of the carrier, because then a particularly large work space is available below the work spindle.
Eine sehr häufig einsetzbare Ausgestaltung der erfindungsgemäßen Vorrichtung besteht darin, dass eine Bearbeitungsein- richtung als ein Werkzeugträger zur Aufnahme von Dreh-, Bohr- und/ oder Fräswerkzeugen ausgebildet ist. Hierdurch können die verschiedensten spanabhebenden Bearbeitungen eines Werkstückes oder eines bereits zusammengesetzten Werkteiles ausgeführt werden.A configuration of the device according to the invention that can be used very frequently is that a machining device is designed as a tool carrier for receiving turning, drilling and / or milling tools. As a result, a wide variety of machining operations can be carried out on a workpiece or an already assembled workpiece.
Weiterhin kann eine Bearbeitungseinrichtung eine Schleifeinrichtung sein.Furthermore, a processing device can be a grinding device.
Eine vorteilhafte Ausgestaltung besteht darin, dass eine Bear- beitungseinrichtung eine Halte- und Positioniereinrichtung für eines der zusammenzufügenden Teile eines herzustellenden komplexen Teiles ist und die Arbeitsspindel ein anderes Teil haltend zur Durchführung eines Fügevorganges oder Pressvorganges dient. Hierdurch können innerhalb des Funktionberei- ches der Werkzeugmaschine zumindest zwei Teile eines komplexen Werkteiles zusammengefügt werden .An advantageous embodiment consists in that a processing device is a holding and positioning device for one of the parts to be assembled of a complex part to be produced and the work spindle holding another part serves to carry out a joining process or pressing process. As a result, within the functional area ches of the machine tool at least two parts of a complex workpiece are joined.
Um im Nachgang nach einem Fügevorgang die einzelnen Teile eines komplexen Teiles fest miteinander verbinden zu können oder eines der Teile härten zu können, ist es vorteilhaft, wenn eine Bearbeitungseinrichtung eine Laser- Schweißeinrichtung oder Laser- Härteeinrichtung umfasst, da die Verbindungsvorgänge und Härtevorgänge innerhalb des Funktionsbereichs der Werkzeugmaschine durchgeführt werden können, wofür es bisher notwendig war, die einzelnen Teile auf unterschiedlichsten Werkzeugmaschinen zu fertigen .In order to be able to firmly connect the individual parts of a complex part to one another or to harden one of the parts after a joining process, it is advantageous if a processing device comprises a laser welding device or laser hardening device, since the connection processes and hardening processes are within the functional range the machine tool can be carried out, for which it was previously necessary to manufacture the individual parts on a wide variety of machine tools.
Im Sinne der Konzentration der verschiedenen Bearbeitungs- Vorgänge im Funktionsbereich der Werkzeugmaschine liegt es auch, wenn eine Bearbeitungseinrichtung eine Bürsteinrichtung ist, so dass die Werkzeuge beispielsweise nach dem Schweißen oder Härten gereinigt werden können.In terms of the concentration of the various machining processes in the functional area of the machine tool, it is also appropriate if a machining device is a brush device, so that the tools can be cleaned, for example, after welding or hardening.
Wenn außer einem Fügevorgang die Arbeitsspindel auch an einem Pressvorgang beteiligt ist, so ist es wegen der dabei auftretenden hohen Kräfte die auf die Lagerung der Arbeitsspindel einwirken vorteilhaft, wenn die Arbeitsspindel in ihrem Träger festklemmbar ist. Hierdurch ist es möglich die beim Pressvorgang auftretenden hohen Kräfte von den Lagern der Arbeitsspindel fern zu halten. Beim Pressvorgang ist dann erforderlich, das Transportsystem mit speziellen Einrichtungen zu versehen, damit der Gegendruck aufgenommen werden kann.If, in addition to a joining process, the work spindle is also involved in a pressing process, it is advantageous, because of the high forces that occur, which act on the bearing of the work spindle if the work spindle can be clamped in its carrier. This makes it possible to keep the high forces occurring during the pressing process away from the bearings of the work spindle. During the pressing process, it is then necessary to provide the transport system with special devices so that the counter pressure can be absorbed.
