ABSTRACT:
Work-rest for use primarily with machine tools, provided with a prehensile, selfcentering, automatic and double-acting equipment. This equipment is composed of a tern of rollers, whose centripetal simultaneous displacement, that assures the coaxiality of the workpiece, is realized by a pair of symmetrical double-acting grooves made on interchangeable lever arms whose angular movement is enslaved to the axial sliding of a central push rod double acting, grasping and expanding. The interchangeability of the arms of the double-acting prehensile equipment makes possible the use of only one work-rest body for a larger dimensional range of workpieces, both from the outside and from the inside with a considerable saving of operating cost.
