Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables rational winding in a motor winding insertion operation that requires a plurality of coil windings of different sizes as coils constituting one pole, and also provides a simple coil insertion process. It is an object of the present invention to provide a coil winding insertion machine that directly inserts an electric wire into a tool.

Some conventional coil winding insertion machines insert the wire into a coil insertion jig after winding a specified number of turns of wire around the winding frame. As the length of the coil insertion jig increases, the blade portion of the coil insertion jig becomes longer, which poses a problem in that it becomes difficult to manufacture.

In addition, in order to compensate for this drawback, in a coil winding insertion machine that sequentially drops the coil into a coil insertion jig while winding it on a winding frame, the winding order is changed from a small diameter winding frame to a large diameter winding frame. The only thing I could do was repeat the winding.

Therefore, the crossover wire between the poles passes from the largest coil of one pole to the smallest coil of the other pole, and this crossover wire and the coil constituting one pole come into contact, creating a potential difference at the contact point. In the manufacture of motors with high power supply voltages or motors with a small number of poles, it is necessary to protect these crossover wires by wrapping them with an insulating material, or to increase the strength of the insulation coating of the wires.

The present invention aims to provide a coil winding insertion machine that improves these drawbacks.

That is, the present invention is a coil winding insertion machine that sequentially drops the coil into a coil insertion jig while winding the coil onto a winding frame, in order to eliminate the problem of potential difference in the connecting wire between poles. The present invention provides a coil winding insertion machine capable of winding a wire onto a winding frame, or winding a wire from a large diameter winding frame to a small diameter winding frame, according to an arbitrary winding order set in advance.

The present invention will be described below with reference to drawings showing one embodiment thereof.

In the present invention, winding frames are provided on the coil insertion jig side and the fryer side, and the winding frame pieces 2, 3, 4, 5, etc. for winding each coil are provided on the coil insertion jig side winding frame 1, and the winding frame pieces 2, 3, 4, 5, etc. for winding each coil are provided. Frame pieces 2, 3, 4
．． 5 is composed of a pin or a crescent-shaped rod to correspond to the required concentric coil shape, and either the entire winding frame 1 moves up and down, or each winding frame piece 2, 3, 4, and 5 moves individually. It has a mechanism that moves it up and down.

From now on, the number of winding frame pieces 2, 3, 4, and 5 are attached in accordance with the number of coils constituting one pole.

On the other hand, the flyer side winding frame 6 has a winding frame piece 7 around which each coil is wound.
, 8, 9, 10, etc., and the individual winding frame pieces move up and down, or alternatively, the winding frame is structured in steps as shown in Fig. 1, and the whole body moves up and down. ing.

In addition, the electric wire 21 wound around the winding frame 6 is attached to the plate 1.
7, 18, 19, 20 and one of the winding frame pieces 2, 3, 4, 5 on the coil insertion jig side. Board 1
A swash plate 22 to which parts 2, 13, 14, 15, and 16 are attached is provided via a bearing 24.

This bearing 24 is attached to the rotating shaft 23 at an angle. Therefore, when the rotating shaft 23 rotates once, the flyer 11 rotates once and the outer circumference of the swash plate 22 attached to the outer ring of the bearing 24 moves up and down sequentially. Wire push plates 12, 13, 14, 15, 16 attached to swash plate 22 for movement
When the wire pusher plate 13 is at the highest point, the wire pusher plate 15, which is located at the opposite position with respect to the rotating shaft 23, comes to the lowest point, and the rotating shaft 23 rotates further until the wire pusher plate 14 reaches the highest point. When the electric wire pushing plate 16 reaches the lowest point.

In this way, the wire pushing plates 12, 13, 14, 15, 16 move up and down as the flyer 11 rotates, so when one of the wire pushing plates 12, 13, 14, 15, 16 is at the highest point, the so that the electric wire 21 is wrapped around the winding 6 of
When the flyer 11 and swash plate 22 are installed, the rotating shaft 23
As the wire rotates, the wire pushing plate at the highest point descends,
Push down the electric wire 21 and the blades 17, 18, 19, 2
0 and the coil insertion jig side winding frame pieces 2, 3, 4,
It will be pushed to the outside of one of the 5.

To explain the winding method of the present invention in more detail, in the process of sequentially winding from the winding frame with the smallest diameter to the winding frame with the largest diameter, first, the flyer side winding frame 6 is moved one step lower. By lowering the wire and pushing it once wrapped around the winding frame piece 10 of the flyer side winding frame 6 with the wire pushing plates 12, 13, 14, 15, and 16, the blade 17 of the coil insertion jig can be pushed without any trouble.
Place it on the outside so that it can slide down.

At the same time, the coil insertion side winding frame 1 is also raised one step.

In this way, the electric wire 21 led through the fryer 11 is wound around the blade 17 and the winding frame piece 2, and the electric wire pushing plates 12, 13, 14, 15, 16 are rotated by the fryer 11. By pushing the wire one after another with a slight delay, the wire 21 slips down from the winding frame piece 10 of the winding frame 6 to the outside of the blade 17 of the coil insertion jig and the outside of the winding frame piece 2 on the coil insertion jig side. go.

By repeating this operation a specified number of turns, the coil winding of the winding frame with the smallest diameter is completed.

Next, the wire is wound on the winding frame with the second smallest diameter, that is, the winding frame composed of the coil insertion jig blade 18 and the coil insertion jig side winding frame piece 3. At this time, the flyer side winding frame 6 Lower it one more step and place it on the winding frame piece 9 of the flyer side winding frame 6.
Wire pushing plate 12, 13, 14, 1
5. By pushing at step 16, the electric wire is positioned so that it can be inserted outside the blade 18 of the coil insertion jig without any hindrance.

At the same time, the winding frame piece 3 on the coil insertion jig side is pulled up one step so that the electric wire guided by the flyer 11 can be wound around the outside of the winding frame piece 3.

In this way, the wire 21 is wound around the blade 18 and the winding frame piece 3, and the wire pushing plates 12, 13, 14,
15.16 slightly slower than the rotation of fryer 11,
When the electric wire is pushed one after another, the electric wire slips down from the winding frame piece 9 of the winding frame 6 to the outside of the coil insertion jig blade 18 and the coil insertion jig side winding frame piece 3.

When this operation is repeated for a specified number of turns, the second smallest coil winding is completed.

In this way, the wire is gradually wound into larger pieces of the winding frame.

Conversely, when winding the wire from the largest diameter winding frame to the smallest diameter winding frame 5, the electric wire 21 comes to the outermost winding frame piece 7 of the flyer side winding frame 6, so that the wire 21 can be wound. Lower it to
Further, the winding frame 1 is raised so that the electric wire 21 comes to the outermost winding frame piece 5 of the coil insertion jig side winding frame 1 and can be wound.

When the fryer 11 is rotated in this manner, the electric wire 21 is wound around the outside of the winding frame piece 7 and the winding frame piece 5, and the wound electric wire is pushed through the wire pushing plates 12, 13 and 1.
Pushing at 4, 15, and 16 allows winding of the largest coil.

Next, when winding the second largest coil,
Winding preparation can be completed by raising the flyer side winding frame 6 by one level and lowering the coil insertion jig side winding frame 1 by one level, and as described above, the rotation of the fryer 11 and the wire pushing plates 12, 13 , 14, 15, and 16, the wound electric wire is slid down to the outside of the blade 19 of the coil insertion jig and the winding frame piece 4.

In this way, coils with gradually smaller diameters are wound.

By the above operations, the coil is wound around the blade of the coil insertion jig and the winding frame piece on the side of the coil insertion jig.
In this way, the winding frame 1 on the side of the wiping coil insertion jig, in which the winding for one pole has been completed, is further lowered, and the coil electric wire is removed from each winding frame piece 2, 3, 4.5.

In addition, when winding multiple coils constituting one pole, first wind the largest diameter coil, wind a part of the specified number of turns to the smallest diameter coil, and then wind the same number of turns. It is also possible to wind the remaining number of turns from the smallest diameter coil to the largest diameter coil using the frame to complete the one-pole coil winding.

In addition, in the above, by moving the flyer side winding frame 6 up and down, the electric wire 21 is once wound around this winding frame 6, and then the electric wire is pushed with the electric wire push rods 12, 13, 14, 15, and 16. As explained, blade 1 of the coil insertion jig
