Abstract

L'invention concerne les machines-outils. Elle a pour objet un mandrin pour tour dont les mâchoires radiales 2 sont commandées par une douille d'entraînement 5 et des griffes de calage 6, 7. Les mâchoires 2 sont chacune divisées en une partie antérieure 2a et une partie postérieure 2b, seule cette dernière étant en prise avec les organes d'entraînement 5, 6. Une pièce d'accouplement 16 mobile peut relier rigidement les deux parties 2a, 2b ou libérer la partie 2a, de sorte que celle-ci peut être déplacée radialement indépendamment de la partie 2b et ainsi être ôtée. Application à la réalisation de mandrins pour tours à mâchoires de serrage facilement échangeables.
