Abstract

PURPOSE:To form a field winding by one winding machine even in the case that the number of slots is different, in the field winding of an outside groove stator. CONSTITUTION:A wire W is inserted into the rocking shaft 6 inserted into a main shaft 5 installed horizontally, and a flier shaft 19 pivoted by a pin 20 is installed at the end of a guide 16 attached to cross the rocking shaft 6 at right angles, and an inclined stage is installed, which is arranged so that a fixing screw attached through a sidewall 1B may incline the flier shaft 19 through a bow-shaped slot. This is provided with a function which enables it to be wound on the field iron core with a tilt angle theta being variable according the number of slots.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention When winding a coil around an armature core of an outer groove stator, the same winding machine is used to form a field winding even when the number of field cores of the armature core is different. It provides a mechanism that can be applied.

[0002]

2. Description of the Related Art Conventionally, in this type of winding mechanism, a winding machine for setting a mounting angle of a nozzle for winding must be provided for each different number of field cores. This requires a lot of man-hours as well as manufacturing cost for this.

[0003]

SUMMARY OF THE INVENTION Even in the case of windings having different numbers of field iron cores, the present invention variably and continuously changes the angle of the flyer shaft for the desired winding by the same device. It provides a mechanism that can respond.

[0004]

1 is a main body according to the present invention (see FIG. 1), the main body 1 has side walls 1A and 1B (see FIGS. 1 and 3), and these side walls are As shown in FIG. 4, the fixing bolt 2 and the fixing sleeve 3 are arranged downward in the downward direction.
The main shaft 5 is mounted by the nut 4 through the side wall 1A (see FIGS. 3 and 6) (see FIG. 6). The main shaft 5 is urged to move forward, reverse, and rotationally by an appropriate means, and as shown in FIG. 6, the swing shaft 6 is inserted and a hollow eyelet 7 is provided at the end portion thereof, and the bearing 9a is provided. Are arranged as shown. W is a wire that is inserted through the swing shaft 6 and also communicates with the nozzle 8. K is an inclined table and is arranged above the main shaft 5 as shown in FIG. 6, and the elongated holes 10 and 10a formed in an arc shape are formed on the side walls 1A and 1B (first and second sides).
(See FIGS. 3 and 4), that is, each main body 1 (see FIG. 1)
Of the washer 12 by fixing screws 14 and 14a provided on both sides of the side walls 1A (see FIGS. 1 and 2) and 1B (see FIG. 6) of the
a, 12b (see FIG. 6), and washers 13, 13a (see FIG. 1) and fixing screws 15, 15a
The other is attached by and is locked so as to have an inclination angle θ ₁ (see FIG. 6). Reference numeral 16 shown in FIGS. 6 and 8 is a guide fitting, which serves to support the tilting table K described above. The structure of the guide fitting 16 will be described. As shown in FIGS. 6 and 8, the guide fitting 16 has a groove 16b in a guide element 16a formed in an H shape, and a through hole 16c for inserting the swing shaft 6. The partition plate 16d is
The leg L is inserted into the groove 16b and is formed into an H shape by the connecting plate C. Above the through holes 20H ₁ and 20H ₂ and the flyer shaft 19, similar through holes 20H ₃ are formed as illustrated. The flyer shaft 19 and the through holes 20H ₁ and 20H ₂ and the through holes 20H ₃ of the flyer shaft 19 are mounted so as to communicate with each other by a pin 20, and the flyer shaft ₁ passes through the connecting plate C of the partition plate 16d.
9 is used for locking so as to be mounted. Further, the swing shaft 6 which is inserted into the through hole 16c of the guide element 16a is attached to the set screw 1
As shown in FIG. 6, it is tightened and laterally installed under the through hole 16c. As shown in FIG. 7, 21 is an armature iron core, 22 is a field iron core, 23 is a field winding, S and S ₁ are slots, and 17 and 17a (see FIG. 3) are openings. It is a thing.

[0005]

When the main shaft 5 is biased by an appropriate means, the rocking shaft 6 rotates together with the tilting table K arranged via the guide fitting 16 attached to the rocking shaft 6, that is, the left and right side walls 1
A and 1B also rotate together. Therefore, when the swing shaft 6 is inserted into, for example, any _one of the slots S and S ₁ of the armature core 21 (see FIG. 7), under the nozzle 8 which is inclined,
The wire W locked on one side can be wound around the field core 22 by rotating the tilting table K together with the rotation of the swing shaft 6, so that the field winding can be wound. When 23 is wound and the required number of turns is reached, the tilting table K is also retracted due to the retraction of the swing shaft 6.

[0006]

EXAMPLE When the main shaft 5 is urged, the tilt table K connected to the swing shaft 6 and the guide fitting 16 is also rotated. That is, when the main body 1 rotates, the nozzle 8 provided on the flyer shaft 19 of the tilt table K.
The wire W locked at one side turns around the field iron core 22 to move forward to form the field winding 23, and then to move backward and turn again to repeat the field winding. Form. Further, from the above, for example, for windings having different numbers of slots of the field core 22, the half angle (tilt angle) θ of the flyer shaft 19
₁ (see FIG. 6) can be set in accordance with the table below, and various windings can be provided.

[0007]

As described above, in the present invention, the elongated holes 10 and 1 for tilting and changing the flyer shaft 19 (see FIG. 6).
The angle of the tilt table K is changed via 0a, and as a result, the nozzle 8 of the flyer shaft 19 can also be freely tilted, which can contribute to various windings of the field winding 23. Further, as shown in the table of the embodiment and FIG. 2, the inclination angle of the flyer shaft 19 corresponding to the number of slots S ₁ , S, etc. is also made variable, so that one model can be used for various kinds of windings. There are benefits to offer.
