Device for holding a rotor blade of an aircraft turbomachine to be machined and its method of mounting on a support arm

Abstract

A holding device (1) for a rotor blade (31) of an aircraft turbomachine to be machined, the holding device (1) comprising jaws (2, 3) configured together to grip, along a longitudinal axis (X), a blade of the rotor blade (31), such that a foot (32) and a heel (33) of the rotor blade (31) project beyond the jaws (2, 3) to be machined, the holding device comprising a connecting surface (6) configured to be removably fixed to a receiving surface of a support arm extending along a support axis, the connecting surface (6) comprising centering elements (7, 8) configured to cooperate with corresponding centering elements of the receiving surface of the support arm to coincide the longitudinal axis (X) and the support axis, the centering elements (7, 8) being orthogonally aligned by relative to the longitudinal axis (X).
