Description

Werkzeugträger für DrehmaschinenTool carriers for lathes
Die vorliegende Erfindung betrifft einen Werkzeugträger, welcher dazu vorgesehen ist zum zerspanenden Bearbeiten eines Werkstückes an der Arbeitsspindel einer Drehmaschine angeordnet zu werden.The present invention relates to a tool carrier which is intended to be arranged on the work spindle of a lathe for machining a workpiece.
Werkzeugträger für Werkzeuge zum Anbringen an der Arbeitsspindel einer Drehmaschine sind bekannt und dienen dazu, Werkstücke aus beliebigem Material zerspanend zu bearbeiten. Je nach auszuführender Arbeit, sind die passenden Werkzeuge auszuwählen und am Werkzeugträger anzubringen, was mit teilweise aufwändigen ümrüstzeiten (Nebenzeiten) verbunden ist. Um dies zu vermeiden, werden konstruktiv komplizierte und kostenaufwändige Revolverköpfe mit unterschiedlichen Werkzeugen eingesetzt. Aufgabe der vorliegenden Erfindung war es, einenTool carriers for tools for attachment to the work spindle of a lathe are known and are used to machine workpieces made of any material. Depending on the work to be carried out, the appropriate tools must be selected and attached to the tool carrier, which is sometimes associated with complex changeover times (non-productive times). To avoid this, structurally complicated and costly turret heads with different tools are used. The object of the present invention was to
Werkzeugträger zu schaffen, welcher bei höchster Präzision sehr einfach aufgebaut ist und Nebenzeiten (Werkzeugwechsel) praktisch gegen Null reduziert.To create tool carrier, which is very simple to build with the highest precision and reduces idle times (tool change) practically to zero.
Diese Aufgabe wird bei einem Werkzeugträger der eingangs definierten Art erfindungsgemäss durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.This object is achieved according to the invention in a tool holder of the type defined in the introduction by the features of the characterizing part of claim 1.
Besonders vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.Particularly advantageous embodiments of the invention are defined in the dependent claims.
Gemäss der Erfindung ermöglicht der Werkzeugträger, zwei unterschiedliche Werkzeuge zu halten und selektiv einzusetzen, wobei die Kosten für die Bauteile des Trägers und deren Zahl minimal gehalten werden können, dies insbesondere, wenn für die Bewegung der Komponenten des Trägers ein einziger Motor eingesetzt wird, dessen Welle sowohl den Schlitten wie auch selektiv die gewünschten Werkzeughalter verschiebt, dies z.B. über einen Hebel mit Innenkurve und zwei Kurvenscheiben oder über zwei Steuerkurven für die beiden Werkzeughalter (Einstechschlitten) , ein Zwischengetriebe und eine Steuerkurve für den Schlitten (Querschlitten) .According to the invention, the tool carrier enables two different tools to be held and used selectively, the costs for the components of the carrier and their number being kept to a minimum, in particular if the movement of the components of the A single motor is used for the carrier, the shaft of which moves both the slide and the desired tool holder selectively, e.g. via a lever with an inner curve and two cam disks or via two control cams for the two tool holders (plunge slide), an intermediate gear and a control curve for the slide (Cross slide).
Der erzwungene Bewegungsablauf erfolgt gesteuert sequentiell oder simultan entlang den Bewegungsachsen X und Y bzw. translatorisch. Dadurch ist sichergestellt, dass die Nebenzeiten bei der Werkzeugselektion auf ein Minimum reduziert sind.The forced movement sequence is controlled sequentially or simultaneously along the movement axes X and Y or translationally. This ensures that idle times in tool selection are reduced to a minimum.
Zur Durchführung komplizierter Bearbeitungsschritte können mehrere Werkzeugträger an der Spindel angeordnet werden (mit je zwei unterschiedlichen Werkzeugen) , vorzugsweise unter Winkelabständen von 120°, was einerseits das Kollisionsrisiko benachbarter Werkzeuge ausschliesst und andererseits die Nebenzeit bei der Werkzeugselektion gegen Null bringt. Dank diesem überraschenden Konzept wird die Produktivität einer Drehmaschine bei niedrigen Kosten nachhaltig erhöht.To carry out complex machining steps, several tool carriers can be arranged on the spindle (each with two different tools), preferably at angular intervals of 120 °, which on the one hand excludes the risk of collision between neighboring tools and on the other hand reduces the idle time during tool selection to zero. Thanks to this surprising concept, the productivity of a lathe is sustainably increased at low costs.
Wenn die Werkzeugträger auf einem längsbeweglichen Schlitten (Werkzeugschlitten) montiert werden, lässt sich der Einsatz jedes Doppelwerkzeuges zusätzlich um eine Arbeitsebene (entlang der Z-Achse) erweitern.If the tool carriers are mounted on a longitudinally movable slide (tool slide), the use of each double tool can also be expanded by a working level (along the Z axis).
Die Erfindung wird nachstehend anhand von in der Zeichnung dargestellten Ausführungsbeispielen und Funktionsabläufen noch etwas näher erläutert. Es zeigt: Fig. 1 rein schematisch die wesentlichen Komponenten eines erfindungsgemässen Werkzeugträgers;The invention is explained in more detail below with reference to exemplary embodiments and functional sequences shown in the drawing. It shows: Fig. 1 purely schematically, the essential components of a tool holder according to the invention;
Fig. 2 einen Werkzeugträger nach der Erfindung mit besonders vorteilhaften Antriebsmitteln in drei bezüglich der Spindel unterschiedlichen Stellungen, undFig. 2 shows a tool holder according to the invention with particularly advantageous drive means in three different positions with respect to the spindle, and
Fig. 3 eine Variante des Werkzeugträgers nach Fig. 2.3 shows a variant of the tool carrier according to FIG. 2.
Figur 1 der Zeichnung zeigt rein schematisch einen Werkzeugträger nach der Erfindung, mit zentralem Antriebsmotor 1, einem Grundträger 8, auf welchem ein quer verschiebbarer Schlitten 5 mit zwei Werkzeughaltern 6,6' angeordnet ist. In den Haltern 6,6' sind unterschiedliche Werkzeuge 9,9' gehalten. Hinter der Abdeckung 10, welche mit dem Schlitten 5 verbunden und verschiebbar ist, befindet sich der eigentliche Antrieb der Steuerelemente 2 und 3,3' (s. Fig. 2) .Figure 1 of the drawing shows purely schematically a tool carrier according to the invention, with a central drive motor 1, a base carrier 8, on which a transversely displaceable carriage 5 with two tool holders 6, 6 'is arranged. Different tools 9, 9 'are held in the holders 6, 6'. Behind the cover 10, which is connected to the carriage 5 and is displaceable, there is the actual drive of the control elements 2 and 3, 3 '(see FIG. 2).
Die Grundplatte 8 ist üblicherweise auf einem Z-Schlitten (nicht dargestellt) aufgebaut, was die zusätzliche gesteuerte Bewegung in Z-Richtung (entlang der Spindel) erlaubt.The base plate 8 is usually built on a Z-slide (not shown), which allows the additional controlled movement in the Z-direction (along the spindle).
Durch die zusätzlichen Z-Bewegungen werden Simultanarbeitsgänge möglich, welche insbesondere für Langdrehautomaten eine massive Produktivitätssteigerung bewirken. Figur 2 illustriert schematisch das Funktionsprinzip des Doppel- bzw. Zwillingswerkzeugträgers:The additional Z movements make simultaneous operations possible, which bring about a massive increase in productivity, especially for Swiss-type automatic lathes. Figure 2 illustrates schematically the functional principle of the double or twin tool carrier:
Der Motor 1 treibt über die Motorwelle 1' die Steuerelemente Hebel 2 und Nocken 3 an. Der Hebel 2 mit einer Innenkurve 2' dient der Auslenkung in Querrichtung (Y) des Schlittens 5 bis an einstellbare Anschläge 4 dar (z.B. Rasterschrauben), wobei die Wegbegrenzung der Mittenstellung (Fig. 2, links aussen) der Werkzeuge 9,9' dient.The motor 1 drives the control elements lever 2 and cam 3 via the motor shaft 1 '. The lever 2 with an inner curve 2 'serves to deflect in the transverse direction (Y) of the slide 5 up to adjustable stops 4 (for example, raster screws), the travel limitation serving the middle position (FIG. 2, left outside) of the tools 9, 9'.
Die zwei Nocken 3,3' dienen dazu, das gewünschte Werkzeug auf den Arbeitsdurchmesser zu bringen (in X-Richtung) .The two cams 3, 3 'serve to bring the desired tool to the working diameter (in the X direction).
Die Verschiebung in Y-Richtung kann wie gezeigt über den Hebel 2 erfolgen (bis zum gewünschten Anschlag, bei Weiterdrehen der Motorwelle wird das Folgeorgan derThe shift in the Y direction can be done as shown using lever 2 (up to the desired stop, if the motor shaft is turned further, the follower of the
Hebelinnenkurve gegen Federkraft weiter bewegt, während der Schlitten still steht) , oder es kann ein separater Antrieb mit Messsystem erfolgen (Angriff z.B. an Längsseite des Schlittens) . Aus Figur 2 geht hervor, wie nach Einstellung derLever inner curve against spring force moves further while the slide is stationary), or a separate drive with measuring system can be used (attack e.g. on the long side of the slide). From Figure 2 shows how after setting the
Mittenstellung des Schlittens 5 (links) der Anschlag für das rechte Werkzeug 9' angefahren wird (Mitte) und danach das Werkzeug 9' über den einen Nocken 3' in Arbeitsstellung zur Spindel 7 hin gefahren wird. Der Verschub der Werkzeuge 9,9' über die zugehörigen Nocken 3,3' erfolgt durch Angriff der Nocken and einer Verlängerung der Werkzeughalter 6, 6' . Letztere werden gegen eine Rückstellkraft (Feder, nicht dargestellt) bewegt, sodass das nicht durch den Nocken angesteuerte Werkzeug immer ausser Arbeitsstellung gehalten wird.Middle position of the slide 5 (left) the stop for the right tool 9 'is approached (center) and then the tool 9' is moved over the one cam 3 'in the working position to the spindle 7. The tools 9, 9 'are moved over the associated cams 3, 3' by the cams engaging and an extension of the tool holders 6, 6 '. The latter are moved against a restoring force (spring, not shown), so that the tool that is not controlled by the cam is always kept out of the working position.
Die Motorwelle 1', ausgehend von der Mittenstellung, ist nach beiden Seiten bis zu 180° verdrehbar. Es können, wie erwähnt, mehrere Werkzeugträger um eine Spindel angeordnet werden, wobei sich die beschriebenen Vorteile vielfach verwenden lassen. Die dabei erreichbare Leistungssteigerung lässt den Ersatz der bis anhin als „unersetzbar" geltenden kurvengesteuerten Drehautomaten zu.The motor shaft 1 ', starting from the central position, can be rotated up to 180 ° on both sides. As mentioned, several tool carriers can be arranged around a spindle, and the advantages described can be used in many ways. The increase in performance that can be achieved thereby makes it possible to replace the cam-controlled automatic lathes that were previously regarded as "irreplaceable".
Figur 3 zeigt eine Variante des Werkzeugträgers nach Figur 2, bei welcher der Steuerhebel 2 (Fig. 2) durch ein Zwischengetriebe 102 und eine Steuerkurve 103 für den Schlitten 105 (Querschlitten) ersetzt wurde (angetrieben vom Antriebsrad 100) . Damit ist sichergestellt, dass der Schlitten 105 in die gewünschte Arbeitsstellung einfahren kann. Durch den Einsatz des Zwischengetriebes 102 ist auch sichergestellt, dass nur ein Antriebsmotor für beide Achsbewegungen erforderlich ist. Die Steuerkurve 103 steuert den Querschlitten 105, die zwei oberen Steuerkurven 106, 106' die Werkzeughalter 107, 107' der beiden Werkzeuge 109, 109'. FIG. 3 shows a variant of the tool carrier according to FIG. 2, in which the control lever 2 (FIG. 2) has been replaced by an intermediate gear 102 and a control cam 103 for the slide 105 (cross slide) (driven by the drive wheel 100). This ensures that the slide 105 can move into the desired working position. The use of the intermediate gear 102 also ensures that only one drive motor is required for both axis movements. The control cam 103 controls the cross slide 105, the two upper control cams 106, 106 'the tool holder 107, 107' of the two tools 109, 109 '.
