Description
Die Erfindung betrifft eine Spannvorrichtung für ein zu bearbeitendes Bauteil, insbesondere für eine zu bearbeitende Gasturbinenschaufel.The Invention relates to a clamping device for a component to be machined, especially for one to be machined gas turbine blade.
Das Spannen von komplex geformten Bauteilen, so zum Beispiel von Gasturbinenschaufeln, bereitet mit aus dem Stand der Technik bekannten Spannvorrichtungen erhebliche Schwierigkeiten. So lassen sich komplex geformte Bauteile entweder gar nicht spannen oder die erforderlichen Spannvorrichtungen sind unhandlich und teuer. Bedingt dadurch, dass das Spannen von komplex geformten Bauteilen nach dem Stand der Technik nur unzureichend möglich ist, bereitet auch die Bearbeitung dieser Bauteile zum Beispiel durch Fräsen Schwierigkeiten.The Clamping of complex shaped components, such as gas turbine blades prepared considerable with known from the prior art fixtures Difficulties. This allows complex components either do not cock at all or are the necessary tensioning devices unwieldy and expensive. Due to the fact that the clamping of complex molded components according to the prior art only insufficient possible is also preparing the machining of these components for example by milling Difficulties.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, eine neuartige Spannvorrichtung für ein zu bearbeitendes Bauteil, insbesondere für eine zu bearbeitende Gasturbinenschaufel, zu schaffen.Of these, Based on the present invention, the problem underlying a novel clamping device for a component to be machined, in particular for one to create gas turbine blade to create.
Dieses Problem wird durch eine Spannvorrichtung gemäß Anspruch 1 gelöst. Die erfindungsgemäße Spannvorrichtung weist mindestens ein mit einem magnetisch-sensitiven oder einem elektrisch-sensitiven oder einem drucksensitiven Medium gefülltes Spannkissen auf, wobei das oder jedes Spannkissen unter Verformung des jeweiligen Spannkissens an eine Fläche des zu bearbeitenden Bauteils anschmiegbar ist, und wobei weiterhin durch Anlegen eines magnetischen Felds oder durch Anlegen eines elektrischen Felds oder durch Aufbringen eines Drucks das oder jedes Spannkissen versteifbar ist, um so das zu bearbeitende Bauteil zu spannen.This Problem is solved by a clamping device according to claim 1. The Inventive clamping device has at least one with a magnetic-sensitive or a electrically-sensitive or a pressure-sensitive medium filled clamping pad on, wherein the or each clamping pad under deformation of the respective clamping pad to a surface of the component to be machined is conformable, and further by applying a magnetic field or by applying a electric field or by applying a pressure of the or each Tensioning pad is stiffened so as to the component to be machined tighten.
Mit der erfindungsgemäßen Spannvorrichtung lassen sich komplex geformte Bauteile, so zum Beispiel Gasturbinenschaufeln, einfach und sicher spannen. Die mit einem magnetisch-sensitiven oder einem elektrisch-sensitiven oder einem druck-sensitiven Medium gefüllten Spannkissen lassen sich an Oberflächen des zu spannenden bzw. zu bearbeitenden Bauteils anschmiegen und durch Anlegen eines magnetischen Felds oder eines elektrischen Felds oder durch Aufbringen eines Drucks versteifen.With the tensioning device according to the invention can be complex shaped components, such as gas turbine blades, easy and safe clamping. Those with a magnetically sensitive or an electrically-sensitive or a pressure-sensitive medium filled Tension pads can be attached to surfaces of the exciting or Nestle to be machined component and by applying a magnetic Field or an electric field or by applying a Stiffen the pressure.
Es ist ein formangepasstes Spannen der komplex geformten Bauteile über einen großen Oberflächenbereich derselben möglich, sodass hohe Bearbeitungskräfte beim Bearbeiten der gespannten Bauteile aufgenommen werden können. Die Spannkissen schmiegen sich jeweils formgenau an die individuelle Oberfläche des zu spannenden sowie zu bearbeitenden Bauteils an. Die erfindungsgemäße Vorrichtung ist demnach für eine Vielzahl unterschiedlicher Bauteile geeignet.It is a form-fitting clamping of the complex shaped components over a large surface area same possible, so high machining forces can be absorbed when editing the tensioned components. The Tightening cushions nestle exactly in shape to the individual surface to be clamped and machined component. The device according to the invention is therefore for a variety of different components suitable.
