Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for inserting circular coils into a stationary armature.

When inserting the coil wound with a winding machine into the stator,
Conventionally, the coil wound with a winding machine was removed from the winding frame after being secured with tape, etc., and then transferred to an insertion jig, and the stator was inserted into the insertion jig to insert the coil. I am doing it.

Recently, the coil has been transferred directly from the winding frame to the insertion jig,
A method has been used in which the stator is fitted into the insertion jig and the coil is inserted, but each method is time-consuming and inefficient.

This invention solves the above-mentioned drawbacks of the prior art, and consists in making it possible to insert a circular coil into a fixed armature extremely quickly, smoothly and reliably.

However, this invention uses a winding machine equipped with a plurality of winding frames corresponding to the number of poles of the stator on the lower side of the winding frame base, and when the winding ends and each winding frame moves toward the center, ,
A guide rod connected to the lower end of each winding frame, or the guide rod and a plurality of fixed guide rods suspended from the winding frame base form an insertion guide jig that hangs concentrically at a predetermined interval. The gist of this method is to insert a circular coil into a fixed armature, which is characterized by inserting a stator into the insertion guide jig and directly inserting the coils wound around each winding frame into the stator.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for inserting a circular coil into a fixed armature according to the present invention will be described below with reference to the drawings.

In the figure, 1 is the winding frame base of the winding machine a, and 1 is a plurality of winding frames arranged concentrically at predetermined intervals below the winding frame base 1, and the winding frames contract and expand in the radial direction. Further, a guide rod 3 is connected to the lower end of each inner frame 2a.

A plurality of fixed guide rods 4 are suspended concentrically from the winding frame base 1 at predetermined intervals, and 5 are fixed guide rods 4.
, 4... shows a stopper that moves up and down inside, and is connected to the insertion cylinder via a connecting rod 6.

7 is a fixing device for the stator 8, 9 is a stator up and down cylinder that moves the fixing device 7 up and down, and 10 is a fryer with an electric wire.
11 to wind the winding frame 2.

Reference numeral 12 denotes a locking pawl that stabilizes the outer frame 2b of the winding frame 2, and releases the engagement with the outer frame 2b at a position where the winding frame 2 moves toward the center, so that the outer frame 2b is fixed as shown in FIG. It is designed so that it can be tilted.

Next, the circular coil insertion order of the present invention will be explained.

First, the electric wire 10 is wound around the winding frame 2 in the state shown in FIG. 3, and winding is started.

That is, the fryer 11 rotates and winds the wire onto the corresponding winding frame 2.

After the winding is finished, the winding frame base 1 rotates at a certain angle,
The next winding frame 2 is then wound.

(See Figure 4) Next, after winding is completed, the winding frames 2, 2... are moved in the direction of the arrow as shown in Figure 5, and the guide rod 3 connected to the lower end of each inner frame 2a is fixed. An insertion guide jig b which is inserted between the guide rods 4 and hangs concentrically with a predetermined interval between the guide rods 3 and the fixed guide rod 4 as shown in FIG. 2 is formed.

Thereafter, the stator 8 is raised to the winding insertion position by the upper and lower cylinders 9, and is inserted into the insertion guide jig b as shown in FIG.

Next, the stripper 5 descends and pushes the coil 10 wound around each winding frame 2 to begin inserting the coil 10 as shown in FIG.

At this time, the locking pawl 12 releases the engagement with the outer frame 2b.

Then, as shown in FIG. 7, the coil 10' is inserted.

Thereafter, the stator 8 descends and the stripper 5 also rises to return to its original position.

In the above embodiment, the insertion guide jig b is formed by the guide rod 3 and the fixed guide rod 4, but depending on the arrangement of the coils, the insertion guide jig can be formed by only the guide rod 3 as shown in FIG. In some cases, b.

According to this invention, as described above, the coil wound on the winding machine can be directly inserted into the stator from the winding frame, so the transfer process can be omitted, and the work efficiency can be significantly improved.

Furthermore, an insertion jig and an insertion machine are not required, and the shape of the molded coil is better than that obtained by using an insertion jig, increasing the product value. Since there is no need to provide it on the frame, the coil circumference can be shortened, which is very economical.
