20130015618 | MOUNTING FOR LOCKING A VANE BY MEANS OF THE BLADE THEREOF DURING MACHINING OF THE ROOT OF SAID VANEAANM Dupouy; OlivierAACI Levallois-PerretAACO FRAAGP Dupouy; Olivier Levallois-Perret FRAANM Chacon; JoseAACI Villeneuve La GarenneAACO FRAAGP Chacon; Jose Villeneuve La Garenne FRAANM Desmars; PhilippeAACI MeulanAACO FRAAGP Desmars; Philippe Meulan FRAANM Heyer; GerardAACI AntonyAACO FRAAGP Heyer; Gerard Antony FRAANM Menguy; Jean-PaulAACI BezonsAACO FRAAGP Menguy; Jean-Paul Bezons FR - A mounting for locking a turbine engine vane that includes a root and at least one portion outside the root. The mounting can machine the outside portion on a machine tool and includes a stationary jaw for receiving the vane, the jaw including at least six points that form abutments and define a positioning reference system for the vane. The mounting also includes a movable jaw to ensure, during machining the outside portion, holding the vane against the stationary jaw by a clamping mechanism onto the vane root. The movable jaw includes a first clamping mechanism exerting pressure on one of the surfaces of the root, the pressure being substantially perpendicular to the surface. The stationary jaw includes a second clamping mechanism exerting pressure on the leading or trailing edge of the root, the pressure being substantially oriented in the direction of the trailing or leading edge of the root. | 01-17-2013 |
20130167337 | METHOD AND MACHINE TOOL FOR ADJUSTING THE CONTOUR OF A TURBINE BLADE ROOT - A method for adjusting a predetermined contour of a turbine blade root including a main salient edge defined by a determined interior angle. The method includes: chamfering the main edge of the contour to obtain two auxiliary salient edges, associated interior angles of which are respectively greater than the interior angle of the main edge; and blunting the auxiliary edges obtained to fine-tune the contour of the blade root. | 07-04-2013 |
20140191455 | DEVICE FOR HOLDING A TURBINE ENGINE BLADE FOR THE PURPOSES OF MACHINING - A device for holding a turbine engine blade for purposes of machining, the device including a support including at least one housing in which at least one block is removably mounted, the block including two jaws presenting an opening for mounting an airfoil of a blade. The block further includes six presser points for pressing against the airfoil, and a movable presser finger for pressing against a pressure side surface or a suction side surface of the blade, the finger being moved by an actuation mechanism such that in a blade clamping position, the presser finger presses the blade against the presser points of the block, which itself is pressed against the support. | 07-10-2014 |
