Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a rotor winding in a DCC coreless morph and a forming apparatus used to carry out the method, and in particular, enables direct skew winding,
This paper proposes a new technology that automates the winding process and saves labor.

BACKGROUND ART Conventionally, the maxon method and the ball tescap method have been known as winding methods for DCC coreless morph rotor windings.

That is, the Maxon method is as follows, and as shown in Fig. 1, a hexagonal-shaped core 1 that is continuous with the mandrel body and a flyer 2 that feeds out the enameled wire 3 while rotating are installed opposite each other. As the flyer 2 rotates, the enamelled wire 3 is wound around the core 1 one after another while shifting its position, and a lead wire 4 is provided at a portion corresponding to each pole, and after the winding is completed, the wire 3 is wound in a hexagonal shape from the core 1. Remove the wire 5 as shown in FIG.

Subsequently, the removed winding 5 is flattened to form a flat plate-like body 6 as shown in FIG. 3, and such a flat-plate body 6 is curled as shown in FIG. By overlapping and bonding the single layer parts at both ends, a cylindrical rotor winding 7 as shown in FIG. 5 is obtained.

However, the biggest drawback of this method is that it requires many complicated processes to obtain the rotor winding 1, resulting in poor productivity, and furthermore, it requires manual work such as pulling out the winding 5 from the thin wire 1. As a result, it is difficult to automate the winding work and save labor, and it is not suitable for mass productivity and has the disadvantage of increasing costs overall.

On the other hand, the ball tescap method (also called the skew one-way method) is as follows.

In this method, six round rod or cylindrical shafts 8 and a fryer 9 are arranged facing each other as shown in FIG. A predetermined number of pins 1 are provided on the surface of the shaft 8 at predetermined intervals, depending on the position and the number of poles corresponding to the intended winding size.
Many 0's are planted.

According to this, as the flyer 9 rotates, the enameled wire 11 is moved to the pin 1 in a relationship corresponding to the tilting direction.
0, while being wound around the heart motion 8 one after another.

After winding the enameled wire 11 around each pin 10 several turns at a time, the six shafts 8 are rotated by a predetermined angle, and the wire is similarly wound around the adjacent pin 10.

In this way, as shown in FIG. 7, a cylindrical rotor winding 12 in which the enamelled wires 11 cross each other is obtained.

However, according to such a winding method, the enameled wire 11
are aligned on the circular plane of the six axes 8, but each pin 10
In some parts, several wires are overlapped, so the enamel may peel off and cause a layer short between the wires.Due to the structure of the 6-shaft 8 and the winding work, the outer diameter of the enamelled wire 11 used is constant. There are various drawbacks, such as the limitation of

The present invention has been made to improve the various drawbacks of the conventional technology, and in particular, to form a rotor winding in a new C coreless morph, which aims to improve the efficiency of winding work without using the above-mentioned pins. A method and forming apparatus are provided.

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 8 is a perspective view showing the main parts of the winding forming apparatus according to the present invention, in which 13 is the six axes of the mandrel body;
Support members 14.15 are attached to two locations in the axial direction of 3 so as to be rotatable over a certain range. U-shaped spring plates 16.17 are attached by screws 18 and 19, and a lip guide mounting member 20.21 with a thinner end portion is interposed at the end of these spring plates 16.17. It is attached by screws 22 and 23 as shown in FIG.

24.25 is a screw 26.2 attached to each of the above mounting members 20.21.
The lip guides 24 and 25 are attached to the lip guides 24 and 25, and the distal ends of the lip guides 24 and 25 have an arcuate shape that closely follows the circumferential surface of the six shafts 13, relative to the base thereof.

Note that 28 and 29 are annular step portions that protrude to sandwich the winding surface 30 on which the windings of the six shafts 13 are to be performed, and act to determine the length of the winding wire. The six shafts 13 are arbitrarily separated near the portions 28 and 29, and the six shafts 13 of the wound wire can be removed from the winding surface.

On the other hand, a flyer 32 which rotates and feeds out the enameled wire 31 faces diagonally so as to face the six shafts 13.

Next, a method for forming rotor windings using the apparatus constructed as described above will be described.

First, the enameled wire 31 is pulled out from the flyer 32.
The end portion of the fryer 32 is engaged with a stopper (not shown) near the support member 15, and the fryer 32 is rotated in the direction of arrow A in the figure, and the six shafts 13 are also slowly rotated in the direction of arrow B.

The rotation of the fryer 32 is synchronized with the rotation of the six shafts 13, and the six shafts 13 are rotated by an amount corresponding to one turn of the diagonal winding of the enameled wire 31 on the winding surface 30.

This rotation is performed at a constant speed so that the pitches of the enameled wires 31 on the winding surface 30 are equal.

In this way, the enameled wire 31 is guided on the winding surface 30 by the flyer 32 in fixed amounts.

However, the enameled wires 31 guided in this way are successively and orderly locked to the arcuate tip portions of the lip guides 24 and 25 as shown in FIG.
There is a limit to the amount of locking depending on the thickness of the wire and the number of turns.

Therefore, when the winding by the flyer 31 reaches a predetermined number of times, the rotation of the six shafts 13 and the winding surface 30 is stopped, and only the support members 14 and 15 are
As shown in the figure, it is reversely rotated in the direction of arrow C, which is opposite to the direction of arrow B, and is pulled back to the original starting position.

Furthermore, in this pulled back position, both the six shafts 13 and the lip guides 24 and 25 are moved in the direction indicated by the arrow B, as shown in FIG.
By rotating in the direction of the lip guide 24.
25 and the winding surface 30 again have the flyer 32
After a predetermined amount of enameled wire has been wound, the lip guides 24 and 25 are operated to return to their original positions.

By repeating this operation according to the required number of poles, a rotor winding body 33 as shown in FIG. 12 is formed.

Subsequently, the lip guides 24 and 25 are separated from the winding surface 30, the six shafts 13 are separated near the annular step portions 28 and 29 as described above, and the six shafts 13 are unwound from the winding surface 30. The body 33 is removed while being rotated.

A rotor winding is thus obtained. As is clear from the above description of the embodiments, according to the present invention, the winding operation of the enameled wire, that is, the winding material, on the winding surface of the six axes of the mandrel, that is, the winding shaft, using a flyer can be carried out in a manner that is different from that of the conventional pin. There is no need for work such as driving, and it can be automated by automatic control of the lip guide, which also reduces man-hours, making it possible to automate and save labor for winding, thereby reducing the cost of forming winding. be able to.

In addition, compared to the method of winding wires using pins, this method has advantages such as there is no risk of layer short-circuiting because the winding wires do not overlap, and there are no special restrictions on the diameter of the enamelled wire.

Furthermore, the configuration of the forming apparatus for carrying out the method is extremely simple and inexpensive, and is extremely useful in practice.
