ABSTRACT:
The milling head (1) comprises:
a principal body (2),
an interposed piece (5), which is mounted to rotate on the principal body (2) and which is equipped with a first crown gear (12a),
means for driving and for blocking in rotation the interposed piece (5) with respect to the body (2),
a spindle-holder (3), which is mounted to rotate along axis XX' with respect to the interposed piece (5), on which is fixed a second crown (12b) adapted to mesh with the first crown (12a), and which is mobile in translation along axis XX' between a position of blockage in rotation in which the crown gears (12a, 12b) mesh in one another, and a position of setting in rotation in which the two crown gears (12a, 12b) are out of mesh,
means (13) for setting in translation the spindle-holder (3) between the positions of blockage and of setting in rotation,
and means (17, 18, 19) for setting in rotation the spindle-holder (3) along axis XX'.
The axis of rotation of the interposed piece (5) with respect to the principal body (2) merges with the axis of rotation XX' of the spindle-holder (3), and the means for driving and blocking this interposed piece (5) in rotation allow its continuous adjustment in rotation by any angle along axis XX'.
