Description

Doppelspindel- WerkzeugmaschineDouble spindle machine tool
Die Erfindung betrifft eine Doppelspindel-Werkzeugmaschine.The invention relates to a double-spindle machine tool.
Aus der DE 101 19 175 AI ist eine derartige Werkzeugmaschine bekannt, mittels derer zwei Werkstücke parallel bearbeitet werden können. Dieser Werkzeugmaschine weist einen Ständer auf, auf dem ein x-Schlitten horizontal angeordnet ist, auf dem wiederum zwei vertikal verfahrbare y-Schlitten angeordnet sind. Auf den y-Schlitten ist jeweils eine in z-Richtung verschiebbare Werkzeugspindel angeordnet. Im Arbeitsraum sind ortsfest zwei Werkstück-Träger vorgesehen, an denen zu bearbeitende Werkstücke aufgespannt werden. Bei langen Arbeitswegen in z-Richtung führt dies zu einem Durchhang der Werkzeugspindeln. Die negativen Auswirkungen dieses Durchhanges auf die Präzision des Bearbeitungsvor- ganges lassen sich nur durch komplizierte Kompensationsverfahren ausgleichen. Für Werkzeugmaschinen mit nur einer Werkzeugspindel ist es daher zur hochgenauen Bearbeitung insbesondere tiefer Bohrungen, die eine besonders genaue Bewegung in z-Richtung erfordern, bekannt geworden, die das Werkstück tragende Werkstückträger in z-Richtung verschieb- bar auszugestalten.Such a machine tool is known from DE 101 19 175 AI, by means of which two workpieces can be machined in parallel. This machine tool has a stand on which an x slide is arranged horizontally, on which in turn two vertically movable y slides are arranged. A tool spindle which can be displaced in the z direction is arranged on the y-slide. In the work area there are two fixed workpiece carriers on which workpieces to be machined are clamped. With long working distances in the z direction, this leads to a sag of the tool spindles. The negative effects of this sag on the precision of the machining process can only be compensated for by complicated compensation procedures. For machine tools with only one tool spindle, it has therefore become known for high-precision machining, in particular of deep bores, which require a particularly precise movement in the z direction, that the workpiece carrier carrying the workpiece can be displaced in the z direction.
Der Erfindung liegt die Aufgabe zugrunde, eine Doppelspindel- Werkzeugmaschine so auszugestalten, dass eine hochgenaue Bearbeitung möglich ist.The object of the invention is to design a double-spindle machine tool in such a way that highly precise machining is possible.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. Durch die erfindungsgemäßen Maßnahmen wird erreicht, dass eine hochpräzise Verschiebung des Werkstücks in z-Richtung erreicht wird, wohingegen die die spanende Bearbeitung ausführenden Werkzeuge in z-Richtung unverschiebbar sind. Durch die Weiterbildung nach An- spruch 2 wird erreicht, dass eine Dreh- beziehungsweise Schwenkbewegung des Werkstücks hochpräzise ausgeführt werden kann und eventuell notwendige Kompensationen leicht durchführbar sind.This object is achieved by the features of claim 1. The measures according to the invention ensure that a highly precise displacement of the workpiece in the z direction is achieved, whereas the tools performing the machining are immovable in the z direction. Through further training according to Claim 2 ensures that a rotating or swiveling movement of the workpiece can be carried out with high precision and any necessary compensations can be carried out easily.
Wenn gemäß Anspruch 4 zwei z-Schlitten vorgesehen sind, können eventuell notwendige Kompensationsbewegungen in dieser Richtung ebenfalls sehr leicht ausgeführt werden. Entsprechendes gilt, wenn entsprechend Anspruch 7 zwei y-Schlitten vorgesehen sind. Wenn schließlich auch noch entsprechend Anspruch 8 zwei x-Schlitten vorgesehen sind, können auch Kompensationen in dieser Richtung sehr einfach durchgeführt werden.If two z-slides are provided according to claim 4, any necessary compensation movements in this direction can also be carried out very easily. The same applies if two y-slides are provided according to claim 7. Finally, if two x-slides are also provided according to claim 8, compensations in this direction can also be carried out very easily.
Die Ansprüche 9 und 10 geben bevorzugte Antriebe wieder.Claims 9 and 10 represent preferred drives.

Die Seiten-Stützen 2, 3 und die Quer-Holme 4, 5 sind durch Hohlprofile gebildet und umschließen einen Innenraum 6, der beidseitig offen ist, und zwar insbesondere zum Arbeitsraum 7 hin. Der Ständer 1 ist über ein Untergestell 8 auf dem Fundament 9 beziehungsweise einer Fundament-Platte 9 abgestützt.The first exemplary embodiment of a double-spindle machine tool shown in FIGS. 1 to 3 has a - seen in the horizontal z-direction - rectangular, approximately square, frame 1 formed by a frame, which extends vertically in the y-direction - kale side supports 2, 3 and in each case a connecting horizontal cross member 4 extending in the x direction and a lower cross member 5 is formed. The side supports 2, 3 and the cross bars 4, 5 are formed by hollow profiles and enclose an interior space 6 which is open on both sides, in particular towards the working space 7. The stand 1 is supported by a base frame 8 on the foundation 9 or a foundation plate 9.
An der dem Arbeitsraum 7 zugewandten Stirnseite des Ständers 1 ist ein ebenfalls rahmenartig ausgebildeter x-Schlitten 10 in x-Richtung verschiebbar angeordnet. Hierzu sind an den Quer-Holmen 4, 5 jeweils eine x-Führungsschiene 11 angebracht, auf denen der x-Schlitten 10 mittels x-Führungs-Schuhen 12 geführt ist. Der Antrieb des x-Schlittens 10 erfolgt mittels eines auf dem x-Schlitten 10 angebrachten x-Motors 13 über eine sich in x-Richtung erstreckende, in den Seiten- Stützen 2, 3 des Ständers 1 drehfest gelagerte x-Kugelrollspindel 14.On the front side of the stand 1 facing the working space 7, a likewise x-shaped slide 10 is arranged so as to be displaceable in the x-direction. For this purpose, an x-guide rail 11 is attached to the crossbars 4, 5, on which the x-slide 10 is guided by means of x-guide shoes 12. The x-carriage 10 is driven by means of an x-motor 13 mounted on the x-carriage 10 via an x-ball screw 14 which extends in the x-direction and is mounted in the side supports 2, 3 of the stand 1 in a rotationally fixed manner.
Auf der dem Arbeitsraum 7 zugewandten Stirnseite des x-Schlittens 10 ist ein in y-Richtung, also vertikal, verschiebbarer y-Schlitten 15 verschiebbar geführt. Hierzu sind an den Seitenbereichen des rahmenartigen x-Schlittens 10 jeweils eine y-Führungsschiene 16 angebracht, auf denen der y-Schlitten 15 mittels y-Führungs-Schuhen 17 verschiebbar geführt ist. Der Antrieb des y-Schlittens 15 erfolgt mittels eines ebenfalls auf dem x-Schlitten 10 angebrachten y-Motors 18 über eine y-Kugelrollspindel 19.On the front side of the x-carriage 10 facing the working space 7, a y-carriage 15 which is displaceable in the y-direction, that is to say vertically, is displaceably guided. For this purpose, a y-guide rail 16 is attached to the side regions of the frame-like x-slide 10, on which the y-slide 15 is guided so as to be displaceable by means of y-guide shoes 17. The y-carriage 15 is driven by means of a y-motor 18 likewise mounted on the x-carriage 10 via a y-ball rolling spindle 19.
Auf dem y-Schlitten 15 befinden sich im Abstand voneinander zwei Werkzeugspindeln 20, 21, die sich in z-Richtung erstrecken und nach vorn zum Arbeitsraum 7 hin und nach hinten durch den inneren Freiraum 22 des x-Schlittens 10 in den Innenraum 6 des Ständers 1 hineinragen. Die Werk- zeugspindeln 20, 21 sind jeweils um eine sich in z-Richtung erstreckende Achse 23, 24 mittels eines Antriebsmotors 25 antreibbar. Die z-Drehachsen 23, 24 weisen einen Abstand in x-Richtung auf. An ihrer dem Arbeitsraum 7 zugewandten Seite können sie jeweils ein spanendes Werkzeug 26 auf- nehmen. Die Werkzeugspindeln 20, 21 sind in x- und y-Richtung relativ zueinander ortsfest auf dem y-Schlitten 15 angebracht, in z-Richtung jedoch unverschiebbar ausgebildet.On the y-slide 15 there are two tool spindles 20, 21 at a distance from one another, which extend in the z-direction and forward to the working space 7 and backwards through the inner free space 22 of the x-slide 10 into the interior 6 of the stand Protrude 1. The factory Tool spindles 20, 21 can each be driven by means of a drive motor 25 about an axis 23, 24 extending in the z direction. The z axes of rotation 23, 24 are spaced apart in the x direction. On their side facing the working space 7, they can each hold a cutting tool 26. The tool spindles 20, 21 are fixed in place in the x and y directions relative to one another on the y slide 15, but are designed to be non-displaceable in the z direction.
Im Arbeitsraum 7 ist vor dem Ständer 1 auf dem Fundament beziehungs- weise der Fundament-Platte 9 ein Werkstück-Träger-Bett 27 gelagert, auf dem ein z-Schlitten 28 in z-Richtung verschiebbar gelagert ist. Hierzu sind auf dem Bett 27 z-Führungsschienen 29 angebracht, auf denen der z-Schlitten mittels z-Führangs-Schuhen 30 verschiebbar abgestützt ist. Der Antrieb erfolgt mittels eines am Werkstück-Träger-Bett 27 angebrachten z-Motors 31 über eine z-Kugelrollspindel 32.In the working space 7, a workpiece carrier bed 27 is mounted on the foundation or the foundation plate 9 in front of the stand 1, on which a z-slide 28 is mounted so as to be displaceable in the z direction. For this purpose, z-guide rails 29 are mounted on the bed 27, on which the z-slide is slidably supported by means of z-guide shoes 30. The drive takes place by means of a z-motor 31 attached to the workpiece carrier bed 27 via a z-ball screw 32.
Auf dem z-Schlitten 28 sind zwei y-Drehtische 33, 34 angebracht, die jeweils mittels eines am z-Schlitten 28 angebrachten Dreh- Antriebsmotors 35, 36 um eine vertikale, also in y-Richtung verlaufende, Drehachse 37, 38 drehantreibbar sind. Die y-Drehachsen 37, 38 haben ebenfalls einen Abstand voneinander.Mounted on the z-slide 28 are two y rotary tables 33, 34, each of which can be driven in rotation by means of a rotary drive motor 35, 36 attached to the z-slide 28 about a vertical axis of rotation 37, 38 which runs in the y direction. The y axes of rotation 37, 38 are also at a distance from one another.
Auf den y-Drehtischen 33, 34 ist jeweils ein Werkstück-Träger 39, 40 angebracht, der ein zu bearbeitendes Werkstück 41, 42 aufnehmen kann.A workpiece carrier 39, 40 is mounted on the y rotary tables 33, 34, which can accommodate a workpiece 41, 42 to be machined.
Die gleichzeitige Bearbeitung der grundsätzlich identischen Werkstücke 41, 42 mittels eines Werkzeugs 26 erfolgt in der Weise, dass die identischen Bewegungen der Werkzeugspindeln 20, 21 in x- und y-Richtung mittels des x-Schlittens 10 und des y-Schlittens 15 ausgeführt werden. Die insoweit ebenfalls identischen Bewegungen der Werkstücke 41, 42 in z-Richtung werden mittels des z-Schlittens 28 ausgeführt. Lediglich die Bewegungen der Werkstücke 41, 42 um die vertikalen y-Drehachsen 37, 38 werden zwar in der Praxis grundsätzlich auch identisch sein, können aber zumindest theoretisch aufgrund des eigenständigen Drehantriebs der Werkstück-Träger 39, 40 um die y-Drehachsen 37, 38 unterschiedlich sein.The simultaneous machining of the fundamentally identical workpieces 41, 42 by means of a tool 26 takes place in such a way that the identical movements of the tool spindles 20, 21 in the x and y directions are carried out by means of the x slide 10 and the y slide 15. The Insofar as identical movements of the workpieces 41, 42 in the z direction are carried out by means of the z slide 28. Only the movements of the workpieces 41, 42 about the vertical y-rotation axes 37, 38 will in principle also be identical in practice, but can at least theoretically, due to the independent rotary drive of the workpiece carriers 39, 40 about the y-rotation axes 37, 38 be different.
Das in den Fig. 4 bis 6 dargestellte zweite Ausführungsbeispiel einer Doppelspindel-Werkzeugmaschine ist mit dem Ausführungsbeispiel nach den Fig. 1 bis 3 insoweit identisch, als es sich um den Ständer 1 mit dem x-Schlitten 10 und dem y-Schlitten 15 und den Werkzeugspindeln 20, 21 handelt. Insofern wird insgesamt auf die obige Beschreibung verwiesen.The second exemplary embodiment of a double-spindle machine tool shown in FIGS. 4 to 6 is identical to the exemplary embodiment according to FIGS. 1 to 3 insofar as it concerns the stand 1 with the x-slide 10 and the y-slide 15 and the Tool spindles 20, 21 acts. In this respect, reference is made to the above description as a whole.
Auf dem Fundament beziehungsweise der Fundament-Platte 9 ist ein Werkstück-Träger-Bett 43 angeordnet, auf dem zwei - bezogen auf eine y-z-Mittelebene - spiegelsymmetrisch zueinander angeordnete z-Schlitten 44, 45 angeordnet sind. Hierzu ist auf dem Bett 43 jeweils ein Paar von z-Führungs-Schienen 46 angebracht, auf denen jeder z-Schlitten 44 beziehungsweise 45 mittels z-Führungs-Schuhen 47 in z-Richtung verschiebbar geführt ist. Der Antrieb jedes z-Schlittens 44, 45 erfolgt mittels jeweils eines am Bett 43 angebrachten z-Motors 48, 49 über eine z-Kugelrollspindel 50.A workpiece carrier bed 43 is arranged on the foundation or the foundation plate 9, on which two z-carriages 44, 45, which are arranged mirror-symmetrically with respect to one another, are arranged — with respect to a y-z center plane. For this purpose, a pair of z-guide rails 46 is mounted on the bed 43, on which each z-slide 44 or 45 is guided so as to be displaceable in the z-direction by means of z-guide shoes 47. Each z-carriage 44, 45 is driven by means of a z-motor 48, 49 attached to the bed 43 via a z-ball screw 50.
An die z-Schlitten 44, 45 ist auf der dem jeweils anderen z-Schlitten 45 beziehungsweise 44 zugewandten Seite ein x-Dreh tisch 51 beziehungsweise 52 angebracht, der mittels eines x-Drehantriebs-Motors 53 beziehungsweise 54 um eine in x-Richtung verlaufende x-Drehachse 55 beziehungsweise 56 drehantreibbar ist. Der jeweilige Drehantriebs-Motor 53 beziehungsweise 54 ist auf dem zugeordneten z-Schlitten 44 beziehungsweise 45 angebracht. Auf jedem x-Drehtisch 51, 52 ist ein Werkstück-Träger 57, 58 angebracht, die - wie die Zeichnung erkennen lässt - aufeinander zu gerichtet sind. Sie können jeweils ein Werkstück 59, 60 aufnehmen.On the z-slide 44, 45 on the side facing the other z-slide 45 or 44, an x rotary table 51 or 52 is attached, which extends by means of an x rotary drive motor 53 or 54 in the x direction The x-axis of rotation 55 or 56 can be driven in rotation. The respective rotary drive motor 53 or 54 is on the assigned z-slide 44 or 45 attached. A workpiece carrier 57, 58 is attached to each x rotary table 51, 52 and, as the drawing shows, is directed towards one another. You can take up one workpiece 59, 60 at a time.
Für die Bearbeitung jedes Werkstücks 59 gilt wiederum, dass die Bewegungen der Werkzeuge 26 in x- und y-Richtung ausschließlich auf der Seite des Ständers 1 erfolgen, wie es oben bereits geschildert wurde. Die Bewegungen der Werkstücke 59, 60 in z-Richtung könnten grundsätzlich unabhängig voneinander erfolgen. Gleiches gilt für die Dreh- beziehungswei- se Schwenkbewegung um die x-Drehachsen 55, 56. In der Praxis ist dies regelmäßig aber nicht erwünscht, da üblicherweise gleiche Werkstücke auf gleiche Weise bearbeitet werden.For the machining of each workpiece 59, it is again the case that the movements of the tools 26 in the x and y directions take place exclusively on the side of the stand 1, as has already been described above. The movements of the workpieces 59, 60 in the z direction could in principle take place independently of one another. The same applies to the rotating or swiveling movement about the x-rotating axes 55, 56. In practice, however, this is not usually desirable, since the same workpieces are usually machined in the same way.
Das in den Fig. 7 und 8 dargestellte dritte Ausführungsbeispiel unterschei- det sich von den zuvor geschilderten Ausführungsbeispielen in der Ausgestaltung des Ständers mit den x- und y-Schlitten. Die Gesamtanordnung und -ausgestaltung des z-Schlittens 28 entspricht der des ersten Ausführungsbeispiels nach den Fig. 1 bis 3. In gleicher Weise könnten selbstverständlich auch die z-Schlitten 44, 45 nach dem zweiten Ausführungsbei- spiel gemäß den Fig. 4 bis 6 eingesetzt werden. Soweit bei dem Ausführungsbeispiel einer Doppelspindel- Werkzeugmaschine nach den Fig. 7 und 8 mit den vorherigen Ausführungsbeispielen identische Teile vorhanden sind, werden die selben Bezugsziffern verwendet. Soweit funktionell gleiche und konstruktiv nur geringfügig abweichende Teile vorgesehen sind, werden die selben Bezugsziffern mit einem hochgesetzten Strich verwendet, ohne dass es jeweils einer gesonderten erneuten Beschreibung bedürfte. Der am Ständer V angeordnete x-Schlitten 10' weist mittig einen vertikalen Zwischensteg 61 auf, so dass nebeneinander zwei Paare von y-Führungs-Schienen 16 an der der Arbeitsseite 7 zugeordneten Stirnseite des x-Schlittens 10' angebracht werden können. Auf diesen y-Führungs- Schienen 16 sind zwei y-Schlitten 62, 63 mittels y-Führungs-Schuhen 17 verschiebbar angeordnet. Der Antrieb der y-Schlitten 62, 63 in y-Richtung erfolgt mittels y-Linear-Motoren 64, 65, deren durch Spulen gebildete Primärteile 66 an den y-Schlitten 62, 63 angebracht sind, während die durch Permanentmagnete gebildeten Sekundärteile 67 am x-Schlitten angebracht sind.The third exemplary embodiment shown in FIGS. 7 and 8 differs from the previously described exemplary embodiments in the configuration of the stand with the x and y slides. The overall arrangement and design of the z-carriage 28 corresponds to that of the first exemplary embodiment according to FIGS. 1 to 3. In the same way, the z-carriages 44, 45 according to the second exemplary embodiment according to FIGS. 4 to 6 could of course also be used become. To the extent that identical parts to the previous exemplary embodiments are present in the exemplary embodiment of a double-spindle machine tool according to FIGS. 7 and 8, the same reference numbers are used. Insofar as functionally identical and structurally only slightly different parts are provided, the same reference numerals are used with a prime, without the need for a separate new description. The x-slide 10 ' arranged on the stand V has a vertical intermediate web 61 in the center, so that two pairs of y-guide rails 16 can be attached next to one another on the end face of the x-slide 10' assigned to the working side 7. Two y-slides 62, 63 are arranged displaceably on these y-guide rails 16 by means of y-guide shoes 17. The y-carriages 62, 63 are driven in the y-direction by means of y-linear motors 64, 65, the primary parts 66 of which are formed by coils are attached to the y-carriages 62, 63, while the secondary parts 67 formed by permanent magnets are on the x -Slides are attached.
Der Antrieb des x-Schlittens 10' erfolgt mittels oberer und unterer x-Linear-Motoren 68, deren durch Spulen gebildete Primärteile 69 am x-Schlitten 10' und deren durch Permanentmagnete gebildete Sekundärteile 70 am Ständer 1' angebracht sind. Auf jedem y-Schlitten 62, 63 ist eine der Werkzeugspindeln 20, 21 angeordnet.The x-carriage 10 'is driven by means of upper and lower x-linear motors 68, the primary parts 69 of which are formed by coils are attached to the x-carriage 10' and the secondary parts 70 of which are formed by permanent magnets are attached to the stand 1 '. One of the tool spindles 20, 21 is arranged on each y-slide 62, 63.
Hinsichtlich der Arbeitsweise ist gegenüber den ersten und zweiten Ausführungsbeispielen aus den Fig. 1 bis 3 beziehungsweise 4 bis 6 nur zu er- ganzen, dass aufgrund der voneinander unabhängigen Verfahrbarkeit der y-Schlitten 62, 63 und damit der von ihnen getragenen Werkzeuge 26 in y-Richtung auch die Bearbeitungsbewegungen in y-Richtung voneinander unabhängig sind.With regard to the mode of operation, in comparison with the first and second exemplary embodiments from FIGS. 1 to 3 and 4 to 6, it can only be achieved that, owing to the mutually independent movability of the y-slides 62, 63 and thus the tools 26 carried by them Direction, the machining movements in the y direction are independent of one another.
Das vierte Ausführungsbeispiel nach den Fig. 9 und 10 unterscheidet sich von dem nach den Fig. 7 und 8 dadurch, dass auch zwei voneinander unabhängige x-Schlitten 71, 72 am Ständer 1" angebracht sind. Der Antrieb der x-Schlitten 71, 72 erfolgt mittels voneinander unabhängiger x-Linear- Motoren 73, 74, deren durch Spulen gebildete Primärteile 75, 76 jeweils am x-Schlitten 71 beziehungsweise 72 angebracht sind, während die durch Permanentmagnete gebildeten Sekundärteile 77, 78 an der Stirnseite des Ständers 1" angebracht sind. Ansonsten wird auf die vorangehende Beschreibung verwiesen.The fourth exemplary embodiment according to FIGS. 9 and 10 differs from that according to FIGS. 7 and 8 in that two mutually independent x-slides 71, 72 are also attached to the stand 1 ". The drive of the x-slides 71, 72 takes place by means of mutually independent x-linear motors 73, 74, the primary parts 75, 76 of which are formed by coils are attached to the x-slide 71 and 72, respectively, while the secondary parts 77, 78 formed by permanent magnets are attached to the end face of the stand 1 ″ . Otherwise, reference is made to the preceding description.
Bezüglich der Arbeitsweise kommt nunmehr noch hinzu, dass die Werkzeugspindeln 20, 21 auch in x-Richtung unabhängig voneinander antreibbar sind.With regard to the mode of operation, the tool spindles 20, 21 can now also be driven independently of one another in the x direction.
Die Fig. 11 und 12 entsprechen den Fig. 5 und 6 des zweiten Ausführungsbeispiels. Zwischen den Drehtischen 51, 52 ist allerdings eine Trag-Brücke 79 angeordnet, die von beiden Drehtischen 51, 52 gemeinsam mittels der entsprechend angesteuerten x-Drehantriebs-Motoren 53, 54 um die dann miteinander fluchtenden x-Drehachsen 55, 56 antreibbar ist. Auf der Trag- Brücke 79 sind Werkstück-Träger angeordnet, die den Werkstück-Trägern 39, 40 aus dem ersten Ausführungsbeispiel nach den Fig. 1 bis 3 entsprechen. Aus diesem Grunde sind in den Fig. 11 und 12 auch die entsprechenden Bezugsziffern verwendet worden. Diese Werkstück-Träger 39, 40 tragen zur gemeinsamen und gleichzeitigen Bearbeitung Werkstücke 41, 42. 11 and 12 correspond to Figs. 5 and 6 of the second embodiment. However, a support bridge 79 is arranged between the rotary tables 51, 52 and can be driven by the two rotary tables 51, 52 together by means of the correspondingly controlled x rotary drive motors 53, 54 about the x rotary axes 55, 56 which are then aligned with one another. Workpiece carriers which correspond to the workpiece carriers 39, 40 from the first exemplary embodiment according to FIGS. 1 to 3 are arranged on the supporting bridge 79. For this reason, the corresponding reference numerals have also been used in FIGS. 11 and 12. These workpiece carriers 39, 40 support workpieces 41, 42 for joint and simultaneous machining.
