Abstract

PURPOSE:To form a winding into a conical shape and increase a space factor by using a nozzle holder sliding while holding an inclination to a longitudinal direction of a central body in an outer rotor winding machine. CONSTITUTION:If a motor (not shown) is operated, a central body 5, an oscillating ring 10 and a nozzle holder 14 rotate together as a rotating shaft 2 rotates. Continuously, a nozzle 11 of the nozzle holder 14 enters between magnetic poles P1, P2 via an oscillating arm 15A(15B) by operation of a stepping motor not shown in the drawing. At the same time, a wire W with one end fixed starts its winding in layers, for example, from a base of the magnetic pole P2 and a locus of winding drawn around the pole P2 by the nozzle holder 14 sliding while rising on the central body 5 takes a conical shape.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention requires an outer rotor winding machine that is narrow in width, such that the slot interval between the magnetic poles to be wound is, for example, leaving a space of about 1.6 mm after winding. The present invention provides a means for attaching a nozzle holder having a structure that allows the winding to be performed.

Conventionally, in this type of winding machine, the locus drawn by the nozzle of the winding machine has a continuous oval shape, so it is easy to wind the wire in a conical shape and increase the space factor. It wasn't.

The present invention will be explained below with reference to the drawings.

1 is an electric motor, and the electric motor 1 is equipped with a hollow rotating shaft 2. For example, magnetic poles P4. of the outer rotor 3 are attached to the rotating shaft 2. A wire W to be wound on Pz etc. is inserted. In particular, the rotation 2 communicates with a rotation shaft 2 which, as shown in FIG. Reference numeral 5 denotes a center body, and a flange 6A is formed on one side and an opening 7 is formed on the other side through a recess 13 of the center body 5, and the above-mentioned trumpet-shaped eyelet 4 is attached to the opening 7 as appropriate. 5, so that it communicates with the hollow of the rotating shaft 2 inserted into the rotary shaft 2. 6B and 6C are flanges of the swing ring 10, and a bottle 12 is inserted into the flange 6B, and the p-nozzle holder 1 is passed through a notch 10A provided in the swing ring 10, which will be described later.
4 and reaches the aforementioned recess 13. 8.9 is the center body 5
This is a presser screw that is inserted into the center body 5 to secure the rotation shaft 2 to the center body 5.

6D is a cap screw for fixing the pin 12.

14 is the nozzle holder mentioned above, and nozzle holder 1
The nozzle 11 is fixed to one side of the eyelet 4 by a set screw 12A, and is provided with a passage hole 11Af for passing the wire W passing through the nozzle 11 through the eyelet 4. Furthermore, the nozzle holder 14 is connected to the opening 1 → notch 10A → flange. It will be constructed across 6A.

In addition, the nozzle 11 is inclined with respect to the longitudinal direction (center line L) of the center body 5 so that it is oriented toward the center ""0" of the outer rotor 3, and the nozzle holder 14 is slidable on the center body 5 according to the inclination angle. That is, the swing ring 10 and the inclined nozzle holder 14 are configured to slide together while maintaining the longitudinal direction and inclination of the center body 5. 15A and 15B are swing arms. (see Fig. 1), - of the swing arm 15A (15B)
On the sides, bearing pins 16A (16B)'e are provided, respectively. Bearings 16C (16D) are mounted in the outer peripheral recess 10B (see Fig. 1) of the swing ring 10 in correspondence with these bearing pins 16A (16B). 18A (18B) is a tightening nut for the swinging arm 15A (15B), which is fitted into the swinging arm 15A (15B) and allows the swinging ring 10 including the nozzle holder 14 and the center body 5 to rotate together with the rotating shaft 2. 20 is a stepping motor, and the stepping motor 20 connects to the swing arm 15A (15B) via a coupling 22 connected to the rotating shaft 21.
) (see FIG. 1) between these swinging arms 15A (
15B) For example, the swing arm 15A is connected to a horizontally installed stabilizer (not shown) by means of a feed screw 23.
(15B), the rocking ring etc. are connected so as to be displaced. 24 is a support body for supporting and indexing the outer rotor 3. The electric motor 1 and the stepping motor 20 are connected through an appropriate control circuit, and the nozzle holder 14 is displaced and cooled. The holder 14 also rotates, and then the nozzle 11 of the nozzle holder 14 moves to the magnetic pole P1. The wire W, which has entered between Pz and is locked on one side, begins to wind, for example, from the base of the magnetic pole P, and then, by the continuous rotation of the feed screw 23 of the stepping motor 20, the wire W is wound on the swing arm 15A.
As the swing ring 10 supported by (15B) retreats, the nozzle holder 14 is displaced in the direction of sliding up the center body 5 and inside the collar 6 while maintaining the required inclination. In other words, the winding locus of the wire W sent out from the nozzle 11 provided in the nozzle holder 14 as the nozzle holder 14 slides up on the central body 5 as the magnetic pole P2 rotates has a conical shape. Therefore, the control after the sliding speed of the nozzle holder 14 and the speed of sliding 9 is controlled by adjusting the control circuit using the stepping motor 20.
: The winding shape of the coil C can be made into a conical shape (see FIG. 2) as it approaches the magnetic pole end. Therefore, when the magnetic pole P2 reaches the required number of turns, by indexing to the next magnetic pole using the outer rotor 3t and the support 24, a conical coil can be achieved over all the magnetic poles.

As described above, the present invention is configured such that the nozzle holder 14 can be wound in an inclined state toward the center O of the outer rotor 3, so that the conical winding is connected to the magnetic pole P1.
+ P2, etc., and as a result, it not only has a large effect of contributing to improving the space factor, but also has the benefit of being able to easily perform winding even when the slot is narrow as described above.
