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

摘要

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.
