Abstract
A positioning assembly for positioning a rotary part to be machined includes a machining fixture and a positioning device having an elastically-deformable diaphragm concentrically mounted to the fixture and defining an annular loading zone which receives an axial force substantially parallel with a center axis of the fixture. The positioning device has circumferentially-spaced engaging segments, fixed to the diaphragm and extending away therefrom, which have contact members that are displaced radially to frictionally engage the rotary part when the axial force is applied to the loading zone of the diaphragm.
