Abstract

L'invention se rattache au secteur technique des accessoires de machines-outils. L'appareil est caractérisé en ce qu'il est constitué par des entailles étagées formées dans la bague entraînée par le mandrin ou la broche de la machine, dans lesquelles sont placées à rotation limitée des cales ou entretoises mobiles en forme de secteurs dont la longueur ou arc est telle qu'ils laissent pénétrer les tenons formés sur le porte-taraud, dans les entailles dans le sens de rotation correspondant au taraudage, tandis qu'ils masquent en partie ces entailles, afin d'empêcher les tenons d'y retomber lorsque le couple est atteint, c'est-à-dire lorsque les tenons se sont désaccouplés des entailles par glissement à l'encontre d'un organe de pression. L'invention s'applique principalement aux mandrins ou broches de taraudage
