【発明の詳細な説明】 本発明は電動機の組立方法に関するものである。[Detailed description of the invention] The present invention relates to a method of assembling an electric motor.
従来、第１０図のような角形の固定子鉄心１を第１１図

つて取り付けていた。Conventionally, a rectangular stator core 1 as shown in FIG. 10 is attached to an end surface 3 of the rectangular stator core 1 from which a coil 2 protrudes, as shown in FIG. 11, with a housing 4 attached using rivets 5 or bolts. Ta.

。To assemble this type of electric motor, first insert a gauge into the air gap 9 between the inner diameter 6 of the stator core 1 and the outer diameter 8 of the rotor 7. After adjusting the clearance with the outer diameter 8 and fixing it, insert the bearing 10 attached to the housing 4 into the rotor shaft 11, attach the housing 4 with rivets 5 or bolts, and adjust the air gap part 9. He was assembling electric motors.
In this case, the gauge inserted into the air gap 9 is removed after assembly. As described above, conventional motors have the disadvantage that it takes time and effort to attach and detach the gauge, and that the fully enclosed electric motor cannot be assembled because it is impossible to remove the gauge.
本発明は前記従来の欠点を改善し、簡単で、しかも精度
よく、電動機を組立てる方法を提供するものである。The present invention improves the drawbacks of the prior art and provides a simple and accurate method for assembling an electric motor.
以下、本発明の一実施例について説明する。An embodiment of the present invention will be described below.
まず、固定子鉄心１２の中央に回転子を受入れる打抜孔
２４及び外周部１３に左右にテーパー面を有する突起１
４と左右にテーパー面を有する切・欠部１５を有する形

定子鉄心１．２の左右にテーパー面を有する切欠部１５
に当接する突部１７を有する可動片１８を、摺動自在に
保持する治具１９を用いて、以下のように組立てる。First, there is a punched hole 24 in the center of the stator core 12 for receiving the rotor, and a protrusion 1 having a tapered surface on the left and right in the outer peripheral part 13.
The stator core 12 is processed into a shape having a notch/cutout portion 15 having tapered surfaces on the left and right sides. Next, as shown in FIGS. 4 and 5, there is a space inside, a fitting hole 16 in the center bottom part into which the rotor shaft can be fitted, and a stator core 1.2 in the side part. Notch portion 15 having tapered surfaces on the left and right sides of
The movable piece 18 having the protrusion 17 that comes into contact with the movable piece 18 is assembled as follows using a jig 19 that slidably holds it.
まず第６図のように治具１９にハウジング２０を設置し
、つぎに回転子２１の軸２２をハウジング２０に装着さ
れた軸受２３に嵌合させた後、治具１９に設けた嵌挿孔
１６に嵌合させて固定する。そして、第７図のように固
定子鉄心１２を設置し、可動片１８を矢印の方向へ移動

８図のようになる。First, the housing 20 is installed on the jig 19 as shown in FIG. 16 and fix it. Then, the stator core 12 is installed as shown in FIG. 7, and the movable piece 18 is moved in the direction of the arrow to fix the stator core 12. When viewed from the top, it looks like Figure 8.
このとき、固定子鉄心１２の打抜穴２４の内径と突起１

欠部１５を可動片１８の固定子鉄心１２に当接する突部
１７で押して固定すれば、固定子鉄心１２の内径２４は
常に一定位置において固定することができる。At this time, the inner diameter of the punched hole 24 of the stator core 12 and the protrusion 1
4 and notch 15 are machined with high accuracy due to press processing as shown in FIG. If the protrusion 17 of the movable piece 18 that contacts the stator core 12 is pressed and fixed, the inner diameter 24 of the stator core 12 can always be fixed at a constant position.
そして、回転子２１の位置も治具１９の嵌挿孔１６によ
つて規制されているため、回転子２１の外径２６と固定

１図のようにセットし、第２図のように固定子鉄心１２

いて締結し、電動機を完成させる。Since the position of the rotor 21 is also regulated by the insertion hole 16 of the jig 19, the outer diameter 26 of the rotor 21 and the inner diameter 24 of the stator core 12 are both regulated by the jig 19. Therefore, the clearance (air gap) between the outer diameter 26 of the rotor 21 and the inner diameter 24 of the stator core 12 is always kept constant. In this state, set the other housing 27 as shown in Fig. 1, and set the stator core 12 as shown in Fig. 2.
are fastened using rivets 29 or bolts through the mounting holes 28 to complete the electric motor.

上のように本発明によればゲージ等の抜取り作業がなく

ができる。Even in the case of a conventional rectangular stator core, it is possible to assemble it by developing the present invention and using a method of regulating it from two directions. However, in this case, it is necessary to ensure the dimensional accuracy of the inner diameter of the stator core with respect to the four sides of the outer periphery, but as in the present invention, dimensional accuracy of the two sides with the protrusion and notch and the punched hole must be ensured. The other two sides can be used as they are with the same width as the slitter to make extra allowance for punching, so the pressing process is not particularly complicated. As described above, according to the present invention, the rotor, stator, and housing can be assembled with high dimensional accuracy using a simple jig without the need for removing gauges or the like, and in a short time.
