スロットｉ中に押込んでいた。[Technical Background of the Invention] Conventionally, a coil insertion device as shown in FIG. 2 has been used to insert a coil a into a stator core A (see FIG. 1) of a rotary electric machine such as a motor. . In the figure, b is a blade guide rod, and a plurality of blade guide rods b are arranged and fixed side by side on the machine base so as to surround the outside of the corresponding blade c, and the upper end surface b ′ of each blade guide rod b is ,
Which is part of the lower surface of each radial tongues A 1 having stator core A is the lower edge A 3 of the inner wall A 2 to form a support portion of the stator core A by contact. The blades c are arranged side by side inside the stator core A, each having a gap m corresponding to a slot i of the stator core A, and a coil a is arranged in the gap m. Reference numeral e is a pusher having radial folds d that are parallel to each other and enter the gap m between the adjacent blades c, and are vertically movable in the circular blade c. In order to insert the coil a disposed between the blades c into the slot i of the stator core A, first, as shown in FIG. 3, the stator core A in which the slot insulator f has been previously inserted into the slot i. Is lowered along the blade c with the inner wall A 2 of each tongue piece A 1 facing the corresponding blade c, and is placed on the upper end surface b ′ of the group of blade guide rods b. Then, by pushing up the pusher e, the coil a arranged in the required gap m of the blade c was pushed into the slot i as shown in FIG.

ロット絶縁物ｆを損傷し、絶縁不良の回転電気機械の発
生率が高くなるという不都合が生じてきた。By the way, recently, in order to improve the performance of the rotary electric machine, the number of coils a to be inserted into the slots i of the stator core A is increased, and the total cross-sectional area of the inserted coils a with respect to the cross-sectional area of the slots i is increased. The ratio (called the space factor) is being increased. Also coil a
The rotating electric machine is becoming smaller by shortening the circumference of the rotating electric machine. If the space factor is increased and the circumferential length of the coil a is shortened as described above, it becomes difficult for the coil a to enter the slot i. Especially when the pusher e is raised in the blade c and the coil a is inserted into the slot i,
At the edge of the bottom of the slot i of the stator core A, the coil a rises while being rubbed through the slot insulator f, but as described above, the higher the space factor, the more the coil a The shorter the circumference of the coil, the greater the force with which the coil presses the edge. Therefore, as shown in FIG. 4, when the coil a is inserted into the slot i, the corner portion g of the slot insulator f is bent and broken, the slot insulator f is damaged, and a rotary electric machine with poor insulation is generated. The inconvenience of higher rates has arisen.

First, the insulator pressing plate 5 is separated from the second position, that is, the blade guide rod b, while the coil a is arranged between the blades c. In this state, the stator core A, in which the slot insulator f has been inserted in advance, is inserted from above the blade c to insert the blade guide rod b.
It is placed on the upper end surface b'of the group. The handle 6'is turned to rotate the cam surface 6, and the mountain portion pushes up the cam follower 9, whereby the hammer 7 is erected upright. This rod 7
By the upright operation, the insulator pressing plate 5 is set to the first position, that is, the position where the recessed portion 3 at one end presses the outer periphery of the coil insertion side end of the slot insulator f. After that, the pusher e is pushed up to pull up the coil a arranged between the blades c and insert it into the slot i. In order to take out the stator core A having the coil a inserted therein from the blade c group, the insulator pressing plate 5 is returned to the second position,
The stator core A may be pulled out above the blade c.

しておかなければならない。[Problems of the Background Art] According to the apparatus described above, the slot insulator f is pressed by the insulator pressing plate 5 when the coil is inserted, so that it is not damaged by the coil a. However, this device
As shown in FIGS. 6 to 7, a plurality of recessed portions 3 are arranged in an arc shape on one insulator pressing plate 5.
Therefore, after the insertion of the coil a into the stator core A is completed, the insulator pressing plate 5 is moved to the second position without being caught in the lower portion of the coil a, so that the insulating pressing plate 5 is not recessed. All the side walls of the portion 3 must be planes parallel to the up-and-down direction OO of the insulator pressing plate 5, as indicated by reference numeral 11 in FIG.

てしまうということがわかった。However, this naturally results in a portion where the inner wall of the recessed portion 3 of the insulator pressing plate 5 and the inner wall of the slot i of the stator core A are slightly deviated from each other. As described above, when the space factor is increased and the circumferential length of the coil a is shortened, when the coil a is inserted into the slot i of the stator core A, the force by which the coil a presses the bottom edge of the slot i is increased. It was found that the slot insulator f became large and the slot insulator f was damaged at the displaced portion even if the above-mentioned displacement was slight.
