DISPOSITIF DE LIAISON ENTRE UNE BROCHE D'UNE MACHINE D'USINAGE ET UN PORTE-OUTIL.

摘要

A tool-holder has a frustoconical outer centering surface which fits over a matching surface of a spindle. At the rearward end of the former surface are two axial slots and two circumferential grooves. Each of the slots receives a key borne by two spring-rings fitted in the grooves. The keys therefore rotate together with the tool-holder but are radially movable so that they can yield when the tool-holder is put in place if they come up against ribs forming part of the coupling components of the spindle.
