DISPOSITIF DE POSITIONNEMENT DE PRECISION

A precision positioning device extending along an axis to be maintained in a first opening of a mechanical part, includes an axial element provided with a passage, a nut, a support and a moveable element, the axial element being integral with the support, and including a first screw thread for mounting the nut on the axial element, the nut providing an axial stop blocking the axial movement of the axial element relative to the nut, the axial element having an end portion including a deformable cylindrical male profile, adapted to cooperate with the inner circumference of the first opening, the deformation or radial expansion of the end of the axial element being driven by the action of the insertion of the moveable element in movement in the passage of the axial element in the direction of the end of the axial element.
