Zur Herstellung des Kraftschlusses in Umfangsrichtung ist die Klemmeinheit 11 insbesondere mit einem Klemmkolben 19 und einer Klemmgabel 18 versehen. Die Klemmgabel 18 weist dabei zumindest einen oberen Gabelarm 21 mit einer Gabelschräge 25 auf. In der in der Figur 2 gezeigten Ausgestaltung umfasst die Klemmgabel 18 zudem einen unteren Gabelarm 22. Zwischen dem oberen Gabelarm 21 und dem unteren Gabelarm 22 ist der Klemmkolben 19 hierbei geführt. Der Klemmkolben 19 ist hier verfahrbar angeordnet. Der Klemmkolben 19 lässt sich hier in eine Klemmrichtung 23 und entgegengesetzt zur Klemmrichtung 23 verschieben. To produce the frictional connection in the circumferential direction, the clamping unit 11 is provided in particular with a clamping piston 19 and a clamping fork 18. The clamping fork 18 has at least one upper fork arm 21 with a fork bevel 25. In the embodiment shown in Figure 2, the clamping fork 18 also includes a lower fork arm 22. Between the upper fork arm 21 and the lower fork arm 22 of the clamping piston 19 is guided in this case. The clamping piston 19 is arranged here movable. The clamping piston 19 can be moved here in a clamping direction 23 and opposite to the clamping direction 23.
Der Klemmkolben weist insbesondere eine Kolbenschräge 20 auf. Die Kolbenschräge 20 liegt insbesondere an der Gabelschräge 25 an. Beim Verfahren des Klemmkolbens 19 in Klemmrichtung 23 wird die Gabelschräge 25 quer zur Klemmrichtung 23 verscho- ben. In der Figur 2 wird beim Verfahren des Klemmkolbens 19 in Klemmrichtung 23 der obere Gabelarm 21 in Pressrichtung 26 gedrückt. Der obere Gabelarm 21 wird in der Arbeitsposition dadurch an eine Wand der Schaufelnut 32 gepresst. Die Klemmrichtung 23 verläuft in der Arbeitsposition der erfindungsgemäßen Montagevorrichtung 10 radial zur Rotationsachse 30. Die Pressrichtung 26 verläuft quer zur Klemmrichtung 23 und im Wesentlichen parallel zur Rotationsachse 30. Der Klemmkolben 19 ist insbesondere ein Pneumatikkolben eines Pneumatikzylinders oder ein Hydraulikkolben eines Hydraulikzylinders . The clamping piston has in particular a piston bevel 20. The piston bevel 20 rests in particular on the fork slope 25. When the clamping piston 19 moves in the clamping direction 23, the fork bevel 25 is displaced transversely to the clamping direction 23. In the figure 2 is pressed in the clamping direction of the clamping piston 19 in the clamping direction 23 of the upper fork arm 21 in the pressing direction 26. The upper fork arm 21 is thereby pressed in the working position on a wall of the blade groove 32. The clamping direction 23 extends in the working position of the mounting device 10 according to the invention radially to the rotation axis 30. The pressing direction 26 extends transversely to the clamping direction 23 and substantially parallel to the rotation axis 30. The clamping piston 19 is in particular a pneumatic piston of a pneumatic cylinder or a hydraulic piston of a hydraulic cylinder.
In den in den Figuren 2 und 3 gezeigten Beispielen verfügt die Schaufelnut 32 über eine in einem Vorsprung 39 positio¬ nierte axiale Stemmnut 35 und eine radiale Stemmnut 37. Die Ausgestaltung der hier gezeigten Schaufelnut 32 entspricht damit der gängigen Weise. Die axiale Stemmnut 35 ist zur Ein- läge eines axialen Stemmstücks 36 und die radiale Stemmnut 37 zur Einlage eines radialen Stemmstücks 38 vorgesehen. Da¬ durch, dass das axiale Stemmstück 36 ein Übermaß aufweist, wird eine an dieser Stelle positionierte Leitschaufel 33 in der Schaufelnut 32 fixiert. Das Verschieben der zu montierenden Leitschaufel 34 auf die Stelle in der Schaufelnut 32 mit den eingelegten Stemmstücken 36, 38 ist Aufgabe des erfindungsgemäßen Montageverfahrens 40. In der Figur 3 wird das erfindungsgemäße Montageverfahren 40 dargestellt. In dem erfindungsgemäßen Montageverfahren 40 wird die zu montierende Leitschaufel 34 in der Schaufelnut 32 der Turbine 31 befestigt. In der gezeigten Situation sind bereits zwei Leitschaufeln 33 in der Schaufelnut 32 in ihrer Endposition. Die zu montierende Leitschaufel 34 soll in Richtung der schon montierten leitschaufeln 33 verschoben werden. In der Endposition der noch zu montierenden Leitschaufel 34 sind hier bereits die Stemmstücke 36 und 38 eingelegt. Hieran schließt das erfin¬ dungsgemäße Montageverfahren 40 an und die zu montierende Leitschaufel 34 wird mittels der Montagevorrichtung 10 in Montagerichtung 16 die Schaufelnut 32 entlanggetrieben. Die Montagevorrichtung 10 und gegebenenfalls das Anschlagteil 17 sind in der Abbildung bereits in Arbeitsposition gebracht. Zunächst wird mittels der Klemmeinheit 11 ein Kraftschluss zwischen Montagevorrichtung 10 und Schaufelnut 32 in Umfangs- richtung hergestellt, insbesondere durch Ausfahren des Klemm- kolbens 19 in Klemmrichtung 23. Nach Herstellung des Kraftschlusses wird anschließend der Stemmkolben 15 betätigt, der eine Kraft in Montagerichtung 16 ausübt. Zwischen dem Stemmkolben 15 und der zu montierenden Leitschaufel 34 ist das Anschlagteil 17 angeordnet. Das Anschlagteil 17 überträgt die vom Stemmkolben 15 aufgebrachte Kraft in Montagerichtung 16 auf die zu montierende Leitschaufel 34 und schiebt diese da¬ durch in Richtung ihrer Endposition. Obwohl die Erfindung im Detail durch das bevorzugte Ausführungsbeispiel näher illustriert und beschrieben wurde, so is die Erfindung nicht durch die offenbarten Beispiele einge¬ schränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den Schutzumfang der Erfindung zu verlassen . In the examples shown in Figures 2 and 3 examples, the blade groove 32 has a positio ned in ¬ a projection 39 and a radial axial Stemmnut 35 Stemmnut 37. Thus the configuration of the blade groove 32 shown here corresponds to the usual way. The axial Stemmnut 35 is to Ein- An axial Stemmstücks 36 and the radial Stemmnut 37 for inserting a radial Stemmstücks 38 is provided. Since ¬ by that the axial Stemmstück 36 has an excess, a positioned at this point vane is fixed in the blade groove 32 33rd The displacement of the guide blade 34 to be mounted on the point in the blade groove 32 with the inserted caulking pieces 36, 38 is the task of the assembly method 40 according to the invention. FIG. 3 shows the assembly method 40 according to the invention. In the assembly method 40 according to the invention, the guide vane 34 to be mounted is fastened in the vane groove 32 of the turbine 31. In the situation shown, two vanes 33 in the blade groove 32 are already in their final position. The vane 34 to be mounted is to be moved in the direction of the already mounted guide vanes 33. In the final position of the still to be mounted vane 34, the Stemmstücke 36 and 38 are already inserted here. Thereto the dung OF INVENTION ¬ proper assembly method 40 connects and to mount the guide vane 34 is driven along by means of the mounting device 10 in the mounting direction 16, the blade groove 32nd The mounting device 10 and optionally the stop member 17 are already brought into the working position in the figure. First, by means of the clamping unit 11, a frictional connection between the mounting device 10 and the blade groove 32 in the circumferential direction is produced, in particular by extending the clamping piston 19 in the clamping direction 23. After the frictional connection has been established, the caulking piston 15 is then actuated, which exerts a force in the mounting direction 16 , Between the stemming piston 15 and the guide vane 34 to be mounted, the stop member 17 is arranged. The stop member 17 transmits the force applied by the Stemmkolben 15 force in the mounting direction 16 on the guide vane 34 to be mounted and pushes this da ¬ towards their final position. Although the invention in detail by the preferred embodiment has been illustrated and described in detail, as not ¬ limited by the disclosed examples is the invention, and other variations can be derived therefrom by the skilled artisan without departing from the scope of the invention.
