Abstract

Montage d'essai (110) pour fixer une pièce présentant un tenon (68) ayant au moins une partie en queue d'aronde. Le montage comporte un support (112) et un piston (114). Le support (112) comporte deux lobes (54A,54B) se faisant face, destinés à bloquer la partie en queue d'aronde du tenon (68) entre les lobes (54A,54B). Le support (112) est configuré pour presser le piston contre le tenon (68) de manière à bloquer celui-ci contre les lobes du support. Pour cela, le support comporte une chambre hydraulique (118) dont une paroi est formée par une surface de réception de pression (114B) du piston, de telle sorte que lorsque la chambre est emplie de fluide sous pression, la pression du fluide remplissant la chambre s'applique sur la surface de réception de pression (114B) du piston, pressant ainsi le piston contre le tenon (68).
