Abstract
Description
Die Erfindung betrifft ein Verfahren zur Bliskherstellung oder -reparatur, bei dem eine in einem Fräsvorgang vorgefertigte Blisk in einer der ursprünglichen Startposition entsprechenden Nulllage in einer weiteren Bearbeitungsvorrichtung positioniert und anschließend spanend fertigbearbeitet wird oder in einem Schweißverfahren repariert und danach mechanisch nachbearbeitet wird oder in einer Messvorrichtung vermessen wird.The invention relates to a method for producing or repairing blisters, in which a blisk prefabricated in a milling process is positioned in a further processing device in a zero position corresponding to the original starting position and then finish machined or repaired in a welding process and then mechanically reworked or in a measuring device is measured.
Durch Schaufelfräsen aus dem vollen Material gefertigte Blisks werden nach dem Abspannen von der Bearbeitungsvorrichtung auf durch im Bearbeitungsprozess entstandene Schäden untersucht und auf einer Koordinatenmessvorrichtung vermessen und müssen gegebenenfalls auf einer NC-programmierten Fräsvorrichtung nachbearbeitet werden. Ein weiterer Nacharbeitsprozess umfasst das Fräsen oder Schleifen der Schaufelspitzen. Bei der Nachbearbeitung oder auch bei der Vermessung muss die Blisk in einer möglichst genauen der ursprünglichen Startposition beim Schaufelfräsen genau entsprechenden Nulllage wieder zu der Bearbeitungsvorrichtung bzw. zu der Messvorrichtung positioniert werden, um den Materialabtrag im richtigen Schaufelbereich vornehmen zu können bzw. eine exakte Messung durchführen zu können. Das Auffinden der richtigen radialen Schaufellage in Bezug auf die Nachbearbeitungs- oder Koordinatenmessvorrichtung erfolgt bisher durch ein zeit- und kostenaufwendiges und zudem fehlerbehaftetes allmähliches Antasten durch Vermessen und Vermitteln.Blisks made from the full material by blade milling are, after being clamped by the processing device, inspected for damage resulting from the machining process and measured on a coordinate measuring device and, if necessary, must be reworked on an NC-programmed milling device. Another reworking process involves the milling or grinding of the blade tips. In the post-processing or also during the measurement, the blisk must be positioned in a precise exact original position at blade milling exactly corresponding zero position back to the processing device or to the measuring device to make the removal of material in the proper blade area can perform an accurate measurement to be able to. The finding of the correct radial blade position with respect to the post-processing or coordinate measuring device is hitherto carried out by a time-consuming and costly and also erroneous gradual probing by surveying and mediating.
Auch bei der Reparatur von Blisks durch Anschweißen neuer Schaufelteile oder durch Laserauftragsschweißen sowie der sich an das Reparaturschweißen anschließenden spanenden Nachbearbeitung muss die Lage der Bliskschaufeln zu der Schweiß- bzw. Fräsvorrichtung so eingestellt sein, dass der Schweißvorgang und die mechanische Nachbearbeitung an der richtigen Stelle entsprechend der ursprünglichen Schaufelform und -lage durchgeführt werden können und die reparierten Blisks höchsten Qualitätsanforderungen genügen. Auch in diesem Fall ist bisher ein aufwendiges und dennoch mit dem Risiko einer nicht fehlerfreien Positionierung behaftetes Ausrichten und Vermessen erforderlich.Also in the repair of blisks by welding new blade parts or by laser deposition welding and subsequent to the repair welding machining reworking the position of the blisk blades must be set to the welding or milling device so that the welding process and the mechanical finishing in the right place accordingly The original blade shape and attitude can be performed and the repaired blisks meet the highest quality requirements. Also in this case, an elaborate and yet with the risk of incorrect positioning positioning alignment and measuring is required.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung oder zum Reparaturschweißen von Blisks anzugeben, das den Zeit- und Kostenaufwand und das Fehlerrisiko bei der lagerichtigen Positionierung der Blisk zur Nachbearbeitungs- oder Reparaturschweißvorrichtung verringert und die Bereitstellung exakt entsprechend der Zeichnung gefertigter Blisks gewährleistet.The invention has for its object to provide a method for producing or repair welding of blisks, which reduces the time and cost and the risk of error in the correct position positioning of the blisk to the post-processing or repair welding device and ensures the provision of exactly manufactured according to the drawing blisks.
Erfindungsgemäß wird die Aufgabe mit einem Verfahren gemäß den Merkmalen des Patentanspruchs 1 gelöst.According to the invention the object is achieved by a method according to the features of
Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments and expedient embodiments of the invention are the subject of the dependent claims.
Der Grundgedanke der Erfindung besteht darin, dass an der Blisk in der Lage genau festgelegte Ausrichtmerkmale angebracht werden, die die genaue Startposition des Werkzeugs beim Fräsen der Bliskschaufeln definieren, wobei die Blisk bei der mechanischen Nachbearbeitung, beim Reparaturschweißen oder Vermessen anhand dieser Ausrichtmerkmale an der jeweiligen Bearbeitungs- oder Messvorrichtung exakt in der ursprünglichen Startposition des Schaufelfräsens positioniert wird. Dadurch wird der Zeitaufwand für die lagerichtige Positionierung der Blisk bei einer späteren Bearbeitung oder Reparatur oder beim Vermessen in einer Messvorrichtung erheblich verringert und Fehler bei der Einstellung der Startposition werden vermieden.The basic idea of the invention is that the blisk is capable of being fitted with precisely defined alignment features which define the precise starting position of the tool during the milling of the blisk blades, the blisk being mechanically reworked, repair welded or measured using these alignment features on the respective blade Machining or measuring device is positioned exactly in the original starting position of the blade milling. As a result, the time required for the positionally correct positioning of the blisk during later processing or repair or when measuring in a measuring device is considerably reduced and errors in the setting of the starting position are avoided.
In Ausgestaltung der Erfindung ist als Ausrichtmerkmal eine zusätzlich in die Blisk eingeformte, strömungsgünstig ausgebildete flache Vertiefung vorgesehen, nach der die Blisk in der Bearbeitungs- oder Messvorrichtung in der – der ursprünglichen Startposition entsprechenden – Nulllage ausgerichtet wird.In an embodiment of the invention, an additionally formed in the blisk, aerodynamically formed shallow depression is provided as Ausrichtmerkmal, after which the blisk is aligned in the processing or measuring device in the - corresponding to the original starting position - zero position.
In weiterer Ausbildung der Erfindung fungieren als Ausrichtmerkmal an der Blisk ohnehin vorhandene, jedoch in der Lage genau definierte Merkmale wie eine Bohrung oder um 180° versetzte Laschen, die bereits zum Zeitpunkt des Schaufelfräsens in einer genau definierten, die Startposition bei der Bearbeitung bestimmenden Lage ausgebildet sind.In a further embodiment of the invention act as Ausrichtmerkmal on Blisk anyway existing, but precisely defined features such as a hole or offset by 180 ° tabs, which formed already at the time of blade milling in a well-defined, the starting position in the processing-determining position are.
In Ausgestaltung der Erfindung sind an dem Ausrichtmerkmal angreifende Positionierungshilfsmittel zur lagerichtigen Positionierung der Blisk in der Nulllage an der Bearbeitungs- oder Messvorrichtung vorgesehen.In an embodiment of the invention, positioning aids acting on the alignment feature are provided for positionally correct positioning of the blisk in the zero position on the machining or measuring device.
Das Positionierungshilfsmittel kann beispielsweise ein in die als Ausrichtmerkmal fungierende Bohrung einfügbarer Abstecker oder eine an der Bearbeitungs- oder Messvorrichtung angebrachte federnd gelagerte, in die Vertiefung eingreifende Kugel sein.The positioning aid can be, for example, a plug insertable into the bore acting as an alignment feature or a spring-mounted ball attached to the machining or measuring device and engaging in the depression.
