巻線ノズル及び巻線機

Japanese Patent JP7378645

B2

This winding nozzle is used in a winding machine for winding a winding onto an iron core to form a coil. The winding nozzle has a columnar outer shape, and a winding is drawn out from a distal end surface of the winding nozzle and moved around the periphery of the iron core so that the winding is wound onto the iron core. The winding nozzle comprises: a first end surface which is a fixed-side end surface attached to a nozzle retaining part of the winding machine; a second end surface which is a distal end surface from which the winding is drawn out; a winding passing part that extends in the longitudinal direction of the winding nozzle from the first end surface to the second end surface so that the winding passes from the first end surface over to the second end surface; and a distal end groove part that is formed in a groove shape in the second end surface in communication with the winding passing part. The distal end groove part extends from a first side surface which constitutes the outer periphery of the winding nozzle to a second side surface which constitutes the outer periphery of the winding nozzle and opposes the first side surface. The winding passing part is disposed so as to be inclined with respect to a center axis extending in the longitudinal direction of the winding nozzle, and the direction in which the winding passing part is inclined with respect to the center axis is opposite to the direction in which the distal end groove part extends.
