Abstract

L'invention concerne un procédé de vérification d'un assemblage par vissage d'au moins une pièce (30, 31) sur une tige filetée (83), dans lequel ladite pièce est en un matériau relativement mou et un élément (40, 41) de rigidification dans une matière relativement dure par rapport à la matière de la pièce est pré-assemblé à la pièce et comporte un orifice (44, 45) destiné à être engagé sur la tige filetée, le vissage étant effectué au moyen d'un outil à détection de couple susceptible de mesurer un angle de rotation jusqu'à un premier seuil de couple et l'épaisseur de l'assemblage étant déduite de l'angle de rotation pour déterminer si la pièce est bien présente.The invention relates to a method of verifying an assembly by screwing at least one part (30, 31) on a threaded rod (83), in which said part is made of a relatively soft material and an element (40, 41). ) of stiffening in a relatively hard material compared to the material of the part is pre-assembled to the part and comprises an orifice (44, 45) intended to be engaged on the threaded rod, the screwing being carried out by means of a torque detection tool capable of measuring an angle of rotation up to a first torque threshold and the thickness of the assembly being deduced from the angle of rotation to determine whether the part is indeed present.
