Zur Demontage der Laufschaufeln, um bei spielsweise verschlissene Laufschaufeln durch neue oder repa rierte Laufschaufeln zu ersetzen, müssen die Sicherungsstifte ausgebohrt werden. Es ist wünschenswert, den Ausbohrprozess automatisiert und so präzise wie möglich durchzuführen. Zum einen kann auf diese Weise der Ausbohrprozess selbst be schleunigt werden. Zum anderen sollen die Sicherungsstifte, die für die Remontage der neuen bzw. reparierten Laufschau feln eingesetzt werden, einen möglichst kleinen Durchmesser aufweisen.

The measuring system according to the invention is part of the effect that it has a simple and inexpensive structure. In addition, it can be made comparatively small, so that it can be a radial guide in existing rotor configurations between adjacent wheel discs in common rotor designs, so that there positioned backup pins are easily accessible to the measuring system.

Zur Erfassung der Relativbewegungen des Prüfkörpers 4 relativ zum Basiskörper 2 in X-, Y- und Z- Richtung entlang der zugehörigen Führungen 5, 6 und 7 umfasst das Messsystem 1 drei Messtaster 17, 18, 19, wobei der erste Messtaster 17 Bewegungen in X-Richtung, der zweite Messtaster 18 Bewegungen in Y-Richtung und der dritte Messtaster 19 Be wegungen in Z-Richtung erfasst. Der erste und der zweite Messtaster 17 und 18 erstrecken sich dabei jeweils in Rich tung der entsprechenden X- bzw. Y-Achse, so dass sie die Be wegung direkt aufnehmen. Der dritte Messtaster 19 erstreckt sich hingegen in Y-Achse und damit senkrecht zur eigentlichen Messrichtung. Er ist auf eine definierte Schrägfläche aufge setzt, so dass anhand der Verstellung des Messtasters 19 in Y-Richtung die Verstellung in Z-Richtung berechnet werden kann. Diese Anordnung des dritten Messtasters 19 wurde ge wählt, um die Abmessungen des Messsystems 1 in Z-Richtung so klein wie möglich zu halten, so dass das Messsystem 1 zur Er fassung der räumlichen Lage von Sicherungsstiften 26 zwischen benachbarten Radscheiben eines Läufers 27 eingeführt werden kann, wie es nachfolgend unter Bezugnahme auf die Figuren 6 und 7 noch näher erläutert ist. Der Prüfkörper 4 ist mit zwei Messspitzen 20 und 21 versehen, die in Z-Richtung miteinander fluchtend angeordnet sind. Grundsätzlich wäre es auch mög lich, nur eine einzelne Zentrierspitze an dem Prüfkörper 4 vorzusehen. An der Oberseite der Befestigungskonsole ist eine Auswerteeinheit 22 positioniert, die einerseits mit den Mess tastern 17, 18 und 19 über entsprechende Datenkabel 23 ver bunden ist und andererseits über Datenkabel 24 mit einer Ma schinensteuerung einer CNC-Bearbeitungsmaschine verbunden werden kann. Ein Teil des Basiskörpers 2, die Befestigungs konsole 9, der Prüfkörperhalter 12 und der Prüfkörper 4 sind von einer Schutzabdeckung 25 umgeben, aus der lediglich die Messspitzen 20 und 21 des Prüfkörpers 4 auswärts vorstehen. For this purpose, two spaced voneinan the spaced apart stops 15 are provided on the test body 4, in which extending in the Z direction return elements 8 are held, the mutually facing free ends one of the Prüfkörperhalter 12 in the Y direction projecting projection 16 between to record oneself. For detecting the relative movements of the test piece 4 relative to the base body 2 in the X, Y and Z directions along the associated guides 5, 6 and 7, the measuring system 1 comprises three probes 17, 18, 19, wherein the first Probe 17 movements in the X direction, the second probe 18 movements in the Y direction and the third probe 19 movements in the Z direction detected. The first and second probes 17 and 18 each extend in the direction of the corresponding X or Y axis, so that they absorb the movement directly. The third probe 19, however, extends in the Y-axis and thus perpendicular to the actual measuring direction. It is placed on a defined inclined surface, so that based on the adjustment of the probe 19 in the Y direction, the adjustment in the Z direction can be calculated. This arrangement of the third probe 19 was ge selected to keep the dimensions of the measuring system 1 in the Z direction as small as possible, so that the measuring system 1 to He Constitution of the spatial position of locking pins 26 between adjacent wheel discs of a rotor 27 can be introduced , as explained in more detail below with reference to Figures 6 and 7. The test specimen 4 is provided with two measuring tips 20 and 21, which are arranged in alignment with one another in the Z direction. In principle, it would also be pos sible to provide only a single centering on the test specimen 4. At the top of the mounting bracket an evaluation unit 22 is positioned on the one hand with the measuring buttons 17, 18 and 19 via corresponding data cable 23 a related party and on the other hand via data cable 24 with a Ma machine control a CNC processing machine can be connected. A part of the base body 2, the mounting bracket 9, the test specimen holder 12 and the test specimen 4 are surrounded by a protective cover 25 from which only the measuring tips 20 and 21 of the specimen 4 protrude outward.
Das Messsystem 1 wird erfindungsgemäß dazu eingesetzt, die räumliche Lage von Sicherungsstiften 26 zu erfassen, die an einem Läufer 27 einer Dampfturbine befestigte Laufschaufeln 28 gegen radial wirkende Kräfte sichern, wie es in Figur 6 dargestellt ist. Die Sicherungsstifte 26, die jeweils gerade mit einem konstanten kreisförmigen Querschnitt ausgebildet sind, sind an ihren stirnseitigen freien Enden jeweils mit einer Zentrierungsvertiefung 29 versehen, wie es insbesondere in Figur 7 gut zu erkennen ist. Die exakte Erfassung der räumlichen Lage solcher Sicherungsstifte 26 ist dahingehend von Bedeutung, dass sie ein ebenso exaktes Ausbohren der Sicherungsstifte 26 ermöglichen, wenn ein Ausbau der Lauf schaufeln 28 gewünscht ist. According to the invention, the measuring system 1 is used to detect the spatial position of securing pins 26, which secure blades 28 attached to a rotor 27 of a steam turbine against radially acting forces, as shown in FIG. The locking pins 26, which are each formed straight with a constant circular cross-section, are each provided at their front-side free ends with a Zentrierungsvertiefung 29, as it is in particular can be clearly seen in Figure 7. The exact detection of the spatial position of such locking pins 26 is to the effect of meaning that they allow an equally accurate drilling of the locking pins 26 when an expansion of the running blades 28 is desired.
Zum Ausbohren der in Figur 6 dargestellten Sicherungsstifte 26 wird in einem ersten Schritt das Messsystem 1 an einer CNC-Bearbeitungsmaschine, die später auch zur Durchführung der Bohrarbeiten eingesetzt wird, unter Verwendung der Mess systemaufnahme 3 montiert und über die Datenkabel 25 mit der Maschinensteuerung verbunden. Anschließend kann das System genullt werden, indem mit einer der Messspitzen 21 ein vorbe stimmter Punkt im Raum angefahren wird. For drilling out the locking pins 26 shown in Figure 6, the measuring system 1 is mounted in a first step on a CNC processing machine, which is also used to carry out the drilling, using the measuring system recording 3 and connected via the data cable 25 to the machine control. Subsequently, the system can be zeroed by one of the measuring points 21 vorbe a certain point in space is approached.
Zum Erfassen der räumlichen Lage der Sicherungsstifte 26 wird ein erster Sicherungsstift, wie es in Figur 8 gezeigt ist, derart angefahren, dass eine der Messspitzen 20, 21 des Mess systems in eine der beiden Zentrierungsvertiefungen ein taucht. Die Messspitze 20, 21 richtet sich während des Ein tauchens aufgrund ihrer schwimmenden Lagerung automatisch aus. Die während dieser Ausrichtung durchgeführten Bewegungen entlang der Führungen 5, 6 und 7 in X-, Y- und Z-Richtungen werden dabei von den zugeordneten Messtastern 17, 18 und 19 erfasst, wobei die erfassten Daten an die Auswerteeinheit 22 übermittelt werden, die aus diesen Daten und den aktuellen Positionsdaten des Messsystems, welche die Maschinensteuerung liefert, die räumliche Position des einen freien Endes des Sicherungsstiftes 26 ermittelt. In gleicher Weise erfolgt auch die Ermittlung der räumlichen Position des zweiten freien Endes des Sicherungsstiftes 26 durch Eintauschen der Messspitze 20, 21 in die entsprechende Zentrierungsvertie fung. Basierend auf diesem Datenpaar der räumlichen Positio nen beider freien Enden des Sicherungsstiftes 26 wird eine beide Positionen miteinander verbindende Gerade und damit die genaue räumliche Lage des Sicherungsstiftes 26 berechnet und gespeichert . In gleicher Weise werden die räumlichen Lagen sämtlicher Sicherungsstifte 26 unter Einsatz des Messsystems 1 ermittelt und gespeichert. For detecting the spatial position of the securing pins 26, a first securing pin, as shown in FIG. 8, is approached in such a way that one of the measuring tips 20, 21 of the measuring system dives into one of the two centering depressions. The measuring tip 20, 21 is automatically aligned during the dive due to their floating storage. The movements made during this alignment along the guides 5, 6 and 7 in the X, Y and Z directions are thereby detected by the associated measuring probes 17, 18 and 19, wherein the detected data are transmitted to the evaluation unit 22, the These data and the current position data of the measuring system, which provides the machine control, determines the spatial position of the one free end of the locking pin 26. In the same way, the determination of the spatial position of the second free end of the locking pin 26 by exchanging the measuring tip 20, 21 tion in the corresponding Zentrierungsvertie done. Based on this data pair of spatial Positio NEN both free ends of the locking pin 26 a both positions interconnecting line and thus the exact spatial position of the locking pin 26 is calculated and stored. In the same way, the spatial positions of all securing pins 26 are determined and stored using the measuring system 1.
In einem weiteren Schritt wird das Messsystem demontiert und, wie es in Figur 9 dargestellt ist, ein Bohrwerkzeug 30 zum Ausbohren der Sicherungsstifte 26 an derselben CNC-Bearbei- tungsmaschine montiert. Auch hier kann das System genullt werden, indem mit der Bohrerspitze der vorbestimmte Punkt im Raum angefahren wird. In a further step, the measuring system is dismantled and, as shown in FIG. 9, a drilling tool 30 for drilling out the securing pins 26 is mounted on the same CNC machining machine. Again, the system can be zeroed by the drill point with the predetermined point is approached in space.
In einem letzten Schritt erfolgt das Ausbohren der Siche rungsstifte basierend auf den vorab berechneten räumlichen Lagen . In a final step, the drilling out of the safety pins takes place based on the previously calculated spatial positions.
