Abstract

PURPOSE:To make chamfering unnecessary and to stabilize caulking strength further, by improving the pressure welding end face of a hone of a melting and pressing tool for ultrasonic caulking into a specific shape. CONSTITUTION:The pressure welding end face of a cylindrical hone 10 is provided with an uneven surface 12 where pyramids having a large number of V grooves meeting at right angles with each other are provided in parallel with each other, and the external circumferential part of the uneven surface 12 is provided with four pieces of stoppers 11 in parallel with each other at equal pitches. When ultrasonic caulking is performed with this hone 10, a side wall of the stopper 11 becomes a guide and a matter making the shaft center of the hone 10 coincide with that of pin 2 becomes easy. Even if the oscillating uneven surface 12 is welded to the tip part of the pin 2 with pressure, a protrusion of the pyramid 13 intrudes into the top surface of the pin 2 and a matter generating a sideslip does not happen. In addition to the above, even if the hone 10 is pressed against the tip part of the pin 2, the tip surface of the stopper 11 is stopped at the surface of a metallic plate 3, a crushed part is kept at a desired height and the crushed part having sufficient strength is obtained.

きるので、近年は広く行われている。(b) Background of the technology A caulking hole is formed in a plate member made of a non-metallic plate such as a metal plate or a printed board9 synthetic resin plate, and a pin made of thermoplastic resin is inserted into the caulking hole. In recent years, heating and softening the tips of pins, crushing them, and applying ultrasonic caulking has been widely practiced in recent years because equipment costs are low and plates can be easily secured together.

Reference numeral 3 designates a metal plate, such as aluminum, which serves as the other plate member. As a means of fixing the thermoplastic resin plate 1 and the metal plate 3 while maintaining a desired spacing, ultrasonic fastening is performed.

A pin 2 passing through the caulking hole 3A of the metal plate 3 is provided at the tip of the boss IA. and pin 2
The tip of the metal plate 3 protrudes beyond the surface of the metal plate 3 by a length that can be crushed.

金属材よりなる棒形のホーンである。4 is a solution pressure tool connected by a cord to an ultrasonic oscillator (not shown). The melt pressure tool 4 has an ultrasonic vibrator 6 mounted inside an outer cylinder 5 that is held by hand. Reference numeral 7 designates a rod-shaped horn made of a metal material connected to the ultrasonic vibrator 6 and whose tip protrudes below the outer tube 5 .

Therefore, the thermoplastic resin plate 1 and the metal plate 3 are firmly attached.

通じて同一符号は同一対象物を示す。(C) Prior art and problems Figure 2 is a diagram showing an example of the conventional ultrasonic caulking method. A diagram showing another example of the sonic crimping method (A)
is a cross-sectional view, and (b) is a cross-sectional view after caulking. The same reference numerals indicate the same objects throughout the figures.

第２図においてホーン８の圧接端面は凹面に形成されて
いる。このようなホーン８でピン２の先端部を加熱軟化
せしめ、圧接端面の突出した外周縁が、金属板３の表面
に当接するまで、ホーン８を押圧して、ピン２の先端部
を圧潰し、かしめる方法である。In FIG. 2, the pressure contact end surface of the horn 8 is formed into a concave surface. The tip of the pin 2 is heated and softened using the horn 8, and the horn 8 is pressed until the protruding outer periphery of the pressure-welding end surface contacts the surface of the metal plate 3, crushing the tip of the pin 2. , is a caulking method.

このように凹面形状の圧接端面で圧潰するので、かしめ
られたピン２の先端部は茸形の凸部となって金属板３の
かしめ孔３Ａの上部に圧着する。よって十分の肉厚があ
り、かしめ強度が強い。Since the pin 2 is crushed by the concave pressing end surface in this manner, the tip of the pin 2 that has been caulked becomes a mushroom-shaped convex portion and is crimped onto the upper part of the caulking hole 3A of the metal plate 3. Therefore, it has sufficient wall thickness and strong caulking strength.

しかしながらホーン８は上下に超音波振動しているので
、凹面状の圧接端面をピン２の先端部に圧接した場合に
、ピン２の先端面とホーン８の圧接端面間で踊り横滑り
を起こし易い。However, since the horn 8 vibrates ultrasonically up and down, when the concave pressure contact end surface is pressed against the tip of the pin 2, the tip surface of the pin 2 and the pressure contact end surface of the horn 8 tend to dance and cause sideways sliding.

圧接端面をピン２の先端部に圧接した場合に、ピン２の
先端面とホーン８の圧接端面間で踊り横滑りを起こし易
い。When the press-contact end surface is press-contacted to the tip of the pin 2, the tip surface of the pin 2 and the press-contact end surface of the horn 8 tend to dance and cause sideways sliding.

その結果第２図（ロ）のようにホーン８の軸心とピン２
の軸心がずれて、ピン２の軸心よりずれた茸形の圧潰部
が生ずる。このためかしめ孔３Ａの一部の縁から外れて
、かしめ強度が弱くなる恐れがある。As a result, as shown in Figure 2 (b), the axis of the horn 8 and the pin 2
The axis of the pin 2 is shifted, resulting in a mushroom-shaped crushed portion that is shifted from the axis of the pin 2. For this reason, there is a possibility that it may come off a part of the edge of the caulking hole 3A, and the caulking strength may be weakened.

第３図のホーン９は、このピン２との軸心ずれを阻止す
るために、圧接端面が凹凸面に形成されている。そして
かしめ孔３Ａの上縁を面取りして、テーパ一部３Ｂを設
けである。The horn 9 shown in FIG. 3 has a press-contact end surface formed with an uneven surface in order to prevent the axis from being misaligned with the pin 2. The upper edge of the caulking hole 3A is chamfered to form a tapered portion 3B.

このようなホーン９で超音波かしめをすると第３図（ロ
）のように、ピン２の先端部はテーパ一部３Ｂに充填さ
れて逆台形に圧潰される。よって圧潰部の強度が十分に
ある良好のかしめをすることができる。When ultrasonic caulking is performed using such a horn 9, the tip of the pin 2 is filled into the tapered portion 3B and crushed into an inverted trapezoid, as shown in FIG. 3(B). Therefore, good caulking with sufficient strength of the crushed portion can be achieved.

しかしかしめ孔３Ａの上縁を面取りする煩わしさがある
ばかりでな（、金属板３が薄板の場合には、面取りがで
きなくなり、かしめ孔３Ａが拡張されてかしめが不可能
になる恐れがある。However, it is a hassle to chamfer the upper edge of the caulking hole 3A (if the metal plate 3 is a thin plate, chamfering will not be possible, and the caulking hole 3A will expand, making caulking impossible). .

（ｄ）発明の目的 本発明の目的は上記従来の問題点に鑑み、ホーンの圧接
端面を改良することにより、面取りが不必要でかしめ作
業が容易でかつ、強度の強い超音波かしめ方法を提供す
ることにある。(d) Object of the Invention In view of the above-mentioned conventional problems, the object of the present invention is to provide an ultrasonic crimping method that eliminates the need for chamfering, facilitates crimping work, and has high strength by improving the pressure welding end surface of the horn. It's about doing.

A pin is inserted into the caulking hole of the plate member, and the tip of the pin protruding from the surface of the plate member is softened and crushed to prevent the horn from shifting, and the stopper prevents the end surface from being pressed. A thick crushed portion is formed between the plate member and the surface of the plate member.

も小さいものである。In FIG. 4, the pressure contact end surface of the cylindrical horn 10 is provided with an uneven surface 12 on which pyramids 13 formed by, for example, a large number of orthogonal grooves are arranged in parallel. Also, the uneven surface 12
Four stoppers 11 having a height Hb are arranged in parallel at equal pitches on the outer periphery. The height Hb of this stopper 11 is a desired dimension equal to the height of the crushed portion of the pin 2 in the caulked state, and is smaller than the protrusion height Ha of the pin 2 protruding from the surface of the metal plate 30.

このようなホーン９で超音波かしめをするとストッパ１
１の側壁がガイドなり、ホーン１０の軸心をピン２の軸
心に合わせることが容易である。When ultrasonic caulking is performed using such a horn 9, the stopper 1
The side wall 1 serves as a guide, and it is easy to align the axis of the horn 10 with the axis of the pin 2.

また振動している凹凸面１２をピン２の先端部に圧接し
ても、角錐１３の突部がピン２の先端面に食い入り摩擦
抵抗が大きくなり、横滑りを起こすことがない。Furthermore, even if the vibrating uneven surface 12 is pressed against the tip of the pin 2, the protrusion of the pyramid 13 bites into the tip of the pin 2, increasing frictional resistance and preventing side slipping.

度が十分にある良好のかしめをすることができる。Furthermore, even if the horn 10 is pressed strongly enough against the tip of the pin 2, the tip of the stopper 11 is locked on the surface of the metal plate 3, so the height of the crushed portion cannot be maintained at the desired value. As shown in FIG. 4(c), a trapezoidal crushed portion approximately aligned with the axis of the caulking hole 3A can be formed. In other words, good caulking with sufficient strength of the crushed portion can be achieved.

It can also be applied to caulking parts such as printed circuit boards that cannot be caulked with metal rivets.
