Abstract
The present invention is directed to a driving tool (1) for driving a rod (R) in rotation, comprising two stators (10, 20), two rotors (11, 21), two connexion means (12, 22) and a driving element (3) connected to the two connection means (12, 22), wherein the driving element (3) is elastically deformable, and wherein the relative angular position of the two rotors can be modulated. The present invention also covers a machine (M) comprising such a driving tool (1) as well as a method of machining a rod (R) using the same.

A driving tool for driving a rod in rotation, comprising a first stator, a first rotor rotated by the first stator, a first connexion means driven by the first rotor and a driving element having a first end mechanically connected to the first connexion means and a second end,
- further comprising a second stator, a second rotor rotated by the second stator, a second connexion means driven by the second rotor wherein the second connexion means is mechanically connected to the second end of the driving element, in that the driving element is an elastically deformable hollow element the diameter of which can be modified according to the relative angular position of its first end and its second end, and in that the relative angular position of the first rotor and the second rotor can vary so as to modify the relative angular position of the first end and the second end of the driving element.
Method for machining a rode wherein the rod is alternatively driven in rotation by a first and a second driving tool and fed to a machining tool, the method comprising:
- a machining step, wherein the rod is clamped and driven in rotation by the first driving tool, while being released by the second driving tool, and wherein the first driving tool is translated along the frame in a controlled manner suitable for the machining operations,
- a feeding step, wherein the rod is clamped and driven in rotation by the second driving tool, while being released by the first driving tool, and wherein the second tool is translated on the frame so as to feed the rod toward the machining tool,
- wherein each of the first and the second driving tools comprises a first stator, a first rotor rotated by the first stator, a first connexion means driven by the first rotor, a second stator-, a second rotor rotated by the second stator, a second connexion means driven by the second rotor, and an elastically deformable driving element, connected to the first connexion means and to the second connexion means, and wherein the release of the rod results from an offset of the relative angular position of the first and the second rotors.
