あった。Problems to be Solved by the Invention However, with this method, when the contact area of the fitting portion 17 is small and electrical continuity such as grounding is required via a taptight screw, problems such as poor continuity due to the contact resistance hole occur. was there.
そこで、本発明は薄板板金のネジ結合において、ネジバ
カを防止し、かつ十分なネジ嵌合接触面積を確保できる
薄板板金のネジ結合方法を提供することを目的とする。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for screwing together thin sheet metals, which can prevent screw looseness and ensure a sufficient screw-fitting contact area.
課題を解決するための手段
本発明は、孔を有する球面状部材を、その孔が薄板板金
のバーリング孔と重なるように、その薄板板金に取り付
け、そのバーリング孔及び前記球面状部材の孔を利用し
て、その薄板板金を他の部品にネジで結合することを特
徴とする薄板板金のネジ結合方法である。Means for Solving the Problems The present invention provides a method for attaching a spherical member having a hole to a thin sheet metal so that the hole overlaps with a burring hole in the thin sheet metal, and utilizing the burring hole and the hole in the spherical member. This is a method for screwing thin sheet metals, which is characterized in that the thin sheet metals are then connected to other parts with screws.
作用
ネジは、先ずバーリング孔に締められ、引続き球面状部
材の孔に締め付けられる。その際、締め付けを強くする
と球面状部材を中心（軸）方向に変形しようとする力が
働くが、軸方向に変形すると孔径は小さくなろうとする
するので、ネジへの食い込み力が増し、破壊強度を増す
。またバーリング孔とネジの嵌合により大きな嵌合接触
面積を得ることができる。The working screw is first screwed into the burring hole and subsequently into the hole of the spherical member. At that time, when the tightening is tightened, a force is applied that tries to deform the spherical member in the center (axial) direction, but as it deforms in the axial direction, the hole diameter tends to become smaller, which increases the biting force into the screw and increases the fracture strength. increase. Furthermore, a large fitting contact area can be obtained by fitting the burring hole and the screw.
実施例
以下、本発明の一実施例を、添付図面に基づいて説明す
る。EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.
第１図において、３１は薄板板金で、バーリング孔３２
が形成されている。また３４は、球面状部材の一例とし
ての球状くぼみである。この球状くぼみ３４はその中央
に孔３２を有している。図示実施例では、この球面状部
材３４は、薄板板金３１の一端部が折り曲げられて一体
形成されたものであるが、別部材でもかまわない。In FIG. 1, 31 is a thin sheet metal, and the burring hole 32
is formed. Further, 34 is a spherical depression as an example of a spherical member. This spherical depression 34 has a hole 32 in its center. In the illustrated embodiment, the spherical member 34 is integrally formed by bending one end of the thin sheet metal 31, but it may be a separate member.
この球面状部材２４は薄板板金：′３１に、バーリング
孔３２を覆うように、［１つその孔３２がバーリング孔
３２と重なるように、取り付けられている。This spherical member 24 is attached to a thin sheet metal 31 so as to cover the burring holes 32 so that one hole 32 overlaps with the burring hole 32.
そして、別の部品３５の孔３６を通してタップタイトネ
ジ３７が、バーリング孔３２及び球状くぼみ３４の孔３
３にセルフタップしてネジ締めする。Then, the taptight screw 37 is inserted through the hole 36 of another part 35 into the burring hole 32 and the hole 3 of the spherical recess 34.
3. Self-tap and tighten the screws.
すなわち、ネジ３７は、先ずバーリング孔３２に締めら
れ、引続き球状くぼみ３４の孔３３に締め付けられる。That is, the screw 37 is first tightened into the burring hole 32 and subsequently into the hole 33 of the spherical recess 34.
その際、締め付けを強くすると球面状部材を中心（軸）
方向Ｂに変形しようとする力が働くか、軸方向に変形す
ると孔径は小さくなろうとするするので、ネジ３７への
食い込み力が増し、破壊強度を増す。またバーリング孔
３２とネジ３７の嵌合により大きな嵌合接触面積を得る
ことができる。At that time, if the tightening is tightened, the center (axis) of the spherical member
If a force is applied to deform the hole in the direction B or if the hole is deformed in the axial direction, the hole diameter tends to become smaller, so the biting force into the screw 37 increases and the breaking strength increases. Further, by fitting the burring hole 32 and the screw 37, a large fitting contact area can be obtained.
