Abstract

PURPOSE:To allow winding work through one winding machine even if the number of slots of armature core is different by employing an inclinable nozzle for winding a wire around the armature core. CONSTITUTION:A nozzle 8 is made inclinable by means of a nozzle supporting shaft 19 and a guide metal 16 being coupled, movably up and down, with an inclining base K through an elongated hole 10a made through the nozzle supporting shaft 19. When a spindle 5 is energized, the inclining base K bearing the guide metal 16 also rotates. Consequently, a wire W inserted into the nozzle 8 on the inclining base K while stopping one end thereof to an armature core is turned around the armature core through turning of the inclining base K thus forming a winding.

1 is a main body according to the present invention (see FIG. 3), the main body 1 is provided with side walls 1A and 1B (see FIG. 6), and these side walls are shown in FIG. The fixing bolt 2 and the fixing sleeve 3 (FIG. 4) are attached to the main body 1 as described above. Reference numeral 4 denotes a nut screwed to the fixing bolt 2 via the fixing sleeve 3 through the side wall 1A. Reference numeral 5 is a main shaft (see FIG. 6), which is provided with a bearing 9a, and in which the rocking shaft 6 is inserted, the wire W (see FIG. 6) is inserted, and the eyelet 7 is inserted through a tilt table K described later. Insert through the nozzle 8. 9a to 9c are bearings of the main shaft 5, respectively. K
(See FIG. 6) An inclined table will be used to explain the configuration. As shown in FIG. 6, it is arranged above the main shaft 5 and arc-shaped elongated holes 10, 10a are formed above the side walls 1A, 1B. A washer 1 that directly passes through these elongated holes 10 and 10a.
2, 12a (see FIG. 3) are provided by fixing screws K ₁ and K ₂ so as to be provided on both 1A and 1B of the main body, respectively.
Washers 13 and 13a (see FIG. 1) are underframes 1
It is attached integrally with the inclined fulcrums 15, 15a arranged on one of the 4, 14a. Reference numeral 16 shown in FIG. 6 is a guide fitting,
The guide fitting 16 is provided through the pin 20 of the guide fitting 16 by operating the set screw 18 to move the guide fitting 16 up and down in the space 17 provided between the opposite side walls 1A and 1B of the main body 1. The pin and nozzle support shaft 19 can be tilted. Reference numeral 21 shown in FIG. 7 denotes an armature core used for implementing the present invention, 22 a field iron core, and 23 a field winding.

[0005]

When the main shaft 5 is biased, the tilting base K, which is supported by being connected to the guide fitting 16 provided integrally with the main shaft 5, also rotates. As a result, the wire W is inserted into the nozzle 8 of the tilt table K and one of the wires W is locked to the field core 22 by the rotation of the tilt table K around the field core 22.
A field winding 23 is formed by swirling and winding.

[0006]

Example: Loosen the fixing screws K ₁ and K ₂ (see FIG. 4), and then operate the set screw 18 (see FIG. 6) to guide the guide fitting 1.
6 is lowered and the nozzle 8 is lowered to, for example, θ ₁ , the angle θ ₁ for winding the nozzle 8 is 10 ° (see FIG. 2).
Therefore, the angle can be adjusted to half of the angle θ shown above, that is, the winding machine for 18 slots can be used instead of the 9 slots of the armature core 21 due to the angle 20 ° of the previous nozzle 8.

[0007]

As described above, in the present invention, the guide fitting 1 for connecting the tilting base K so as to move up and down through the elongated holes 10 and 10a of the nozzle support shaft 19 (see FIG. 6).
In the present invention, the tilt angle of the nozzle 8 can be variably changed from 4.3 ° to 20 ° as shown in FIG. 2 by making the nozzle 8 tiltable by the nozzle 6 and the nozzle support shaft 19. , Number of slots is 9, 12, 1
There is a real benefit of winding up to 8, 24, 40 armature cores.
