The device allows the broaching of thin-walled workpieces with high precision and an excellent surface condition. It comprises mainly a fixed support defining a radial abutment surface, a sleeve defining ramps, wedge-shaped members bearing against said ramps and against the outer surface of the workpiece. These wedge-shaped members are carried by a plate which is capable of being brought to a wedging position under the effect of springs or to a disengaged position by means of ramps.

Support for broached workpieces

The object of the invention is to improve the performance over a period of time and ensure a constant pre-stressing force of the axial retaining device for a tripod homokinetic joint. For this purpose, surfaces carried by the tulip member, which act as bearing surfaces for part-spherical surfaces carried by the tripod of the joint, comprise recesses of concave shape and of a radius of curvature which is slightly larger than the radius of curvature of the part-spherical bearing surfaces carried by the tripod.
