<p>The machine for the actuation of needles (68,76) for the realization of electric motors field windings is made of a case (10) internally supporting a main shaft (12) in revolving mode which is set in rotation by motor means (11); on the main shaft, means (16,17,18) that perform an up and down oscillating motion at each complete rotation of the said shaft are pivoted in oscillating mode around an axis which is perpendicular to the axis of the shaft; at one end of such means a winding shaft (35) is pivoted, into which are through cables (80) that realize the winding on the slots of a stator, the winding shaft performs a reciprocating traverse motion driven by the said oscillating means; on the winding shaft a tube (39) supporting the winding needles is concentrically inserted in oscillating mode, and it is set in reciprocating rotatory motion by kinematic motion means (44,51,53) connected to the main shaft which accomplish an oscillation of the tube for each stroke end of the winding shaft; on the free ends (60) of the tube and of the shaft concentric to it the winding needles are applied, which are equipped with reciprocating traverse and oscillating motion. <IMAGE></p> |
