MOUNTING FOR LOCKING A VANE BY MEANS OF THE BLADE THEREOF DURING MACHINING OF THE ROOT OF SAID VANE

摘要

The invention relates to a mounting for locking a turbine engine vane (1) that includes a root (2) and at least one portion outside the root. Said mounting is intended for machining said outside portion on a machine tool and includes a stationary jaw (6) for receiving said vane, said jaw having, defined thereon, at least six points that form abutments and define a positioning reference system for said vane on said stationary jaw. Said mounting also includes a movable jaw (7) that is intended to ensure, during the operations of machining said outside portion, the holding of said vane against said stationary jaw (6) by at least one means for clamping onto the vane root (2). The movable jaw (7) comprises a first clamping means (11) that exerts pressure on one of the surfaces of the root, said pressure being substantially perpendicular to said surface. Said mounting is characterized in that the stationary jaw comprises a second clamping means (21) that exerts pressure on the leading or trailing edge of said root, said pressure being substantially oriented in the direction of said trailing edge or said leading edge of said root respectively.
