本発明は小型電気部品等の組立に利用するのに
適した軟質金属材に硬質金属杆を固定する方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing a hard metal rod to a soft metal material suitable for use in assembling small electrical components.
従来から、軟質金属材１に穿設した孔２に孔２
の内径Ｙよりもやや大なる直径Ｘを備えた端部３
を有する硬質金属杆４を、端部３を強制的に孔２
に圧入して固定する方法が公知である（第１図及
び第２図参照）。しかしながらこの方法を採用し
た場合には次の様な不都合が生じる。 Conventionally, a hole 2 is inserted into a hole 2 drilled in a soft metal material 1.
end 3 with a diameter X slightly larger than the inner diameter Y of
A hard metal rod 4 with a hole 2 is forced through the end 3.
A method of press-fitting and fixing is known (see FIGS. 1 and 2). However, when this method is adopted, the following disadvantages occur.
(1) 端部３の直径Ｘは孔２の内径Ｙより大である
から、圧入のための位置決めが微妙で、少々の
ズレがあつても部品が破損されてしまう危険が
ある。(1) Since the diameter X of the end portion 3 is larger than the inner diameter Y of the hole 2, positioning for press-fitting is delicate, and there is a risk that the parts may be damaged even if there is a slight misalignment.
(2) 圧入のために要する力は比較的大であるにも
かかわらず、孔２からの硬質金属杆４の抜去は
割合に簡単で、抜去に抵抗する力が働きにく
い。(2) Although the force required for press-fitting is relatively large, it is relatively easy to remove the hard metal rod 4 from the hole 2, and the force that resists the removal is difficult to act.
本発明はこの様な欠点を除去すべく案出された
もので、圧入が簡単に行えると共に抜去に対して
十分な抵抗力が得られる固定のための方法に関す
るものである。 The present invention has been devised to eliminate these drawbacks, and relates to a fixing method that allows easy press-fitting and provides sufficient resistance against removal.
第３図乃至第５図に就き本発明を説明すると、
１は軟質金属材、２はそれに穿設された内径Ｂを
有する孔、４は端部３を有する硬質金属杆、５は
端部３と案内端６を連結している縮径部であり、
端部３の直径はＡ、案内端６の直径はＣ、縮径部
５の径はＤで示され、各径はＡ＞Ｂ＞Ｃ＞Ｄとな
るように製作されている。 The present invention will be explained with reference to FIGS. 3 to 5.
1 is a soft metal material, 2 is a hole drilled in it and has an inner diameter B, 4 is a hard metal rod having an end 3, 5 is a reduced diameter part connecting the end 3 and the guide end 6,
The diameter of the end portion 3 is indicated by A, the diameter of the guide end 6 is indicated by C, and the diameter of the reduced diameter portion 5 is indicated by D, and each diameter is manufactured so that A>B>C>D.
組立手順は、案内端６を孔２に挿入するとそれ
らの径の関係がＢ＞Ｃ＞Ｄであるので、案内端６
と縮径部５が容易に孔２内に挿入され、端部３の
周縁が孔２の周縁に当接して停止する（第４図参
照）。次に硬質金属杆４を押圧して端部３をＡ＞
Ｂの関係に抗して強制的に孔２内に圧入すると、
硬質金属杆４の本体先端が軟質金属材１に当接し
て停止するまでの間、端部３の先端は孔２の内壁
を押圧しめくり上げつつ前進し、それにより生じ
た押圧歪部２′は縮径部５上にめくれ上つて、案
内端６と端部３の間の空隙部分に詰め込まれる
（第５図参照）。 The assembly procedure is that when the guide end 6 is inserted into the hole 2, the relationship of their diameters is B>C>D, so the guide end 6 is inserted into the hole 2.
The reduced diameter portion 5 is easily inserted into the hole 2, and the peripheral edge of the end portion 3 comes into contact with the peripheral edge of the hole 2 and stops (see FIG. 4). Next, press the hard metal rod 4 to make the end 3
If it is forced into hole 2 against the relationship B,
Until the main body tip of the hard metal rod 4 comes into contact with the soft metal material 1 and stops, the tip of the end portion 3 moves forward while pressing against the inner wall of the hole 2 and turning up, thereby causing a pressing strain portion 2'. is rolled up onto the reduced diameter portion 5 and packed into the gap between the guide end 6 and the end portion 3 (see FIG. 5).
この様に挿入が行われると、案内端６と縮径部
５が容易に孔２内へ侵入できるので、作業開始時
の位置決めが簡単であると共に、押圧歪部２′が
縮径部５上にめくれ上つて塊となり挿入された硬
質金属杆４を軟質金属材１に確実に固定し、更
に、硬質金属杆４の抜去に対しては押圧歪部２′
が案内端６の移動を阻止するので、両者の固定が
強力且つ確実に行える効果があり、加えて作業性
も大巾に向上する利点がある。 When inserted in this way, the guide end 6 and the reduced diameter part 5 can easily enter the hole 2, so positioning at the start of work is easy, and the pressing strain part 2' is placed on the reduced diameter part 5. The hard metal rod 4, which is curled up and inserted into a lump, is securely fixed to the soft metal material 1, and furthermore, when the hard metal rod 4 is removed, the pressed strain part 2'
prevents movement of the guide end 6, which has the effect of strongly and reliably fixing the two, and also has the advantage of greatly improving workability.
