Abstract
【解決手段】ねじ孔3に同軸に連なり且つこのねじ孔3に装着すべきボルトの外径よりも内径d1が大きいツール逃げ孔4が形作られているナット1を、ツール逃げ孔4開口端が対象部材2の表面に向き合うように配置し、ツール逃げ孔4に挿入可能な形状で且つ軸線方向長さL4が対象部材2の厚さt1を上回るピン部10を有するツール本体7を、回転させながら対象部材2裏面のナット1中心に重なっている個所へ押し付け、摩擦熱により軟化した対象部材2にピン部10を突き通し、ナット1を対象部材2に密着させて、この双方を拡散接合する。
この後、接合ツール7を対象部材2から引き抜いて、ピン部10に見合う孔11が形成された対象部材2の塑性変形部位を硬化させる。

Claims (3)
- 機械加工孔とツール逃げ孔が同軸に形作られている機械要素を、ツール逃げ孔開口端が対象部材の表面に向き合うように配置し、ツール逃げ孔に挿入可能な形状で且つ軸線方向長さが対象部材の厚さを上回るピン部を有する接合ツールを、回転させながら対象部材の裏面の機械要素中心に重なっている個所へ押し付け、摩擦熱により軟化した対象部材にピン部を突き通し、この後、接合ツールを対象部材から引き抜き、ピン部に見合う孔が形成された対象部材の塑性変形部位を硬化させることを特徴とする機械要素接合方法。
- ピン部を円柱状のショルダ部に同軸に設けた接合ツールを、当該ショルダ部が対象部材の裏面に摺接するまで押し付けるようにする請求項1に記載の機械要素接合方法。
- ピン部の先端を鈍角状の円錐形とした接合ツールを対象部材の裏面に押し付けるようにする請求項1あるいは請求項2のいずれかに記載の機械要素接合方法。
