Abstract

L'invention concerne un amplificateur électro-hydraulique d'asservissement. Un mécanisme d'entraînement 1 entraîne une tige de mesure 3 pouvant se déplacer en rotation et en coulissement dans un boîtier 2 et ouvrant ou fermant par ses déplacements axiaux et par l'intermédiaire de vannes des conduites de mise en pression et de retour raccordées aux chambres d'un vérin 4. Entre la tige de mesure 3 et le piston 5 du vérin 4 est disposée une piece d'accouplement 7 limitée par des butées 12, 13, dont l'une réglable. L'ordre d'avancement ou de recul d'une pièce 6 est donné par une came 17 par l'intermédiaire d'une vanne 16, sa course est donnée par une butée réglable 14 et sa vitesse de course par le mécanisme d'entraînement 1. L'invention s'applique à la commande de porte-outil montée sur chariot, notamment aux tours à fileter.
