A tool for holding a blade blank (1) comprises a frame (13) in which a control system using clamping jaws (18, 19) and lifters (30, 34, 35) grips the blade and holds it in position vertically on two supporting faces (22, 23), while the blade has been laid on three lateral faces (41, 42, 43). The blade is thus simultaneously held in a precise position and gripped sufficiently tightly, with a single control main mechanism. The mounting of the blade is thus greatly simplified and it may be subjected without further precaution to a manufacturing operation such as welding by friction to a rotor disk.
Un outillage de maintien d'une ébauche d'aube (1) comprend un cadre (13) dans lequel un système de commande à mors (18, 19) et cames (30, 34, 35) assure le serrage de l'aube et la maintient en position verticale sur deux facettes d'appui (22, 23), alors que l'aube a été posée sur trois facettes latérales (41, 42, 43). On concilie donc un maintien de l'aube à une position précise et un serrage suffisant, le tout avec un mécanisme principal à commande unique. Le montage de l'aube est alors très simplifié, et on peut la soumettre sans autre précaution à une opération de fabrication telle qu'un soudage par friction à un disque de rotor.
