グメントとの固着力が弱く、かつ安定せず、均一
な溶接を得ることができないという欠点がある。 However, in the conventional method described above, the ultrasonic vibration during ultrasonic welding weakens as it is transmitted from the upper line part to the underline part of the armature coil, so the adhesion force between the upper line part and the underline part is smaller than that of the underline part. The disadvantage is that the adhesion to the segments is weak and unstable, making it impossible to obtain uniform welding.

The coil 11 wound around 0 is connected to an ultrasonic generation power supply device 12. A horn 13 is attached to the magnetostrictive vibrator 10 and extends in the axial direction to amplify the vibrations of the magnetostrictive vibrator 10.
A chip 14 extending in the direction of the inner diameter of the armature is attached to the anti-vibrator 10 side of the armature. Further, on the inner periphery of this chip 14, there is a U-shaped groove 15 having approximately the same width as the short side of the rectangular conducting wire of the armature coil 3.
is formed. A stepped portion 16 is formed on the inner periphery of the opening of the groove 15 and has a width approximately equal to the width of the armature coil 3 in the long side direction.
Here, the depth L 0 of the groove 15 of the chip 14 is smaller than the long side dimension L of the rectangular conductor of the armature coil,
And (L-L 0 ) is made smaller than the sinking amount A of the tip 14 due to deformation during welding of the rectangular conducting wire of the armature coil 3. In addition, the groove 15 and the stepped portion 16
The overlined portions 3a and the underlined portions 3b are restricted from moving in the radial direction and the circumferential direction, respectively, to prevent the overlined portions 3a and the underlined portions 3b from shifting with respect to the segments 5.

On top of each segment 5 of the commutator 4, an underlined portion 3b is placed with the short side oriented in the radial direction, and an overlined portion 3a is placed on top of the underlined portion 3b with the long side oriented in the radial direction, so that the cross section is inverted T-shaped. It is stated as follows. Then, using an optical sensor or the like, the segment 5 is positioned in correspondence with the groove 15 of the chip 14. Further, after positioning once, the armature side is rotated by a certain angle depending on the number of segments 5, and the segments 5 are positioned with respect to the chip 14.

A stepped portion 16 is disposed in the underlined portion 3b with a gap therebetween, and applies a constant pressure in the direction of arrow P shown in FIG.
Next, power is applied to the coil 11 from the ultrasonic generating power supply device 12 to give vibration to the magnetostrictive vibrator 10. Via the horn 13, the chip 14 is vibrated in the direction of arrow F shown in FIG.

る。 As a result, first, ultrasonic vibration is applied directly to the overlined part 3a via the chip 14, and the overlined part 3a is deformed and firmly connected to the underlined part 3b, and vibration force is also applied to the underlined part 3b, causing the underlined part 3a to deform and firmly connect to the underlined part 3b. Part 3b is also connected to segment 5. Then, the state shown in FIG.
6 hits and applies ultrasonic vibration directly to the underlined portion 3b. Therefore, since the connection area between the overlined part 3a and the underlined part 3b and the connection area between the underlined part 3b and the segment 5 are wide, the connection between the underlined part 3b and the segment 5 is also
The adhesion is stronger and more reliable.

続を得ることが可能である。 Further, as shown in FIG. 4, the width of the U-shaped groove 18 of the tip 14 is set to be the same width as the long side of the rectangular conducting wire of the armature coil 3, so that the tip 14 is attached to the underlined portion 3b during ultrasonic welding. Even if the contact does not occur, the connection force is slightly lower than in the above embodiment, but since the connection area between the underlined portion 3b and the segment 5 is large, it is possible to obtain a sufficient connection.
