Abstract

Dispositif d'essai de dureté de matériau. Le dispositif de la présente invention comprend un adaptateur 30 et un ensemble de pénétration 26. Un logement annulaire 50 pratiqué dans l'adaptateur est en communication avec la base 46 de cet adaptateur par des orifices placés en regard d'une surface 66 annulaire prévue sur la partie supérieure d'un collier 68 entourant le pénetrateur, et relié à lui par un manchon élastique 70. Le débit de l'air circulant dans le logement annulaire et s'échappant par les orifices 58 varie en fonction de la profondeur de pénétration du pénétrateur. Cette variation de débit est détectée et elle est représentative de la dureté de l'échantillon soumis à l'essai. Application à un dispositif automatique permettant d'effectuer des essais sur des pièces individuelles produites à des cadences industrielles afin de contrôler leur conformité à des limites de qualité ou de dureté prescrites.
