Description

【0001】
【発明の属する技術分野】
本発明は、機器にホースを接続するホース継手金具の締結方法及び装置に関し、更に詳しくは、ホース継手金具の構造を変更することなくシール性を向上するようにしたホース継手金具の締結方法及び装置に関する。
【0002】
【従来の技術】
従来、機器にホースを接続するホース継手金具として、加締めタイプのホース継手金具がある。この継手金具は、円筒状のニップル(芯管)とニップルの外周側に配設される円筒状のソケット(外筒)とを有し、専用の締結装置を用いてホースの端部をニップルとソケットとの間に取り付けるようになっている。
【0003】
上記締結装置は、一般に、断面円弧状の押圧面を有する環状に配列した複数の加締め爪を有し、ニップルとソケットとの間にホースの端部を挿入した状態で、ソケットを複数の加締爪により外周側から加締めることにより、ソケットを縮径して挿入したホース端部上に締結するようになっている(例えば、特許文献1参照)。
【0004】
【特許文献1】
特開平8−71863号公報
【0005】
【発明が解決しようとする課題】
しかしながら、複数の加締め爪により円筒状のソケットを外周側から加締める構造上、図6に示すように、加締め時に加締め爪30間に隙間31が生じ、その結果、隙間31が発生した部分でソケット32を効果的に加締めることができない。
【0006】
そのため、その隙間部分において、ホース33の内面とニップル34との間の圧着力が低下し、それによりシール性が低下するという問題があった。特に、反発弾性の低い樹脂材料を主体としたホースを使用した際にシール性が大きく低下し、良好なシール性を確保するのが非常に難しい。
【0007】
本発明の目的は、ホース継手金具の構造を変更することなくシール性を向上することが可能なホース継手金具の締結方法及び装置を提供することにある。
【0008】
【課題を解決するための手段】
上記目的を達成する本発明のホース継手金具の締結方法は、ホース継手金具の円筒状の芯管と該芯管の外周側に配置した円筒状の外筒との間にホースの端部を挿入し、該外筒を断面円弧状の押圧面を有する環状に配列した複数の加締め爪により外周側から加締めることにより、前記外筒を縮径して前記ホースの端部上に締結するホース継手金具の締結方法において、前記加締め爪をホース継手金具長手方向に2列に並ぶ第1加締め爪と第2加締め爪とから構成すると共に、該第1加締め爪と第2加締め爪とを周方向にずらして配置し、前記第1加締め爪と第2加締め爪により前記外筒を加締めることを特徴とする。
【0009】
本発明のホース継手金具の締結装置は、ホース継手金具の円筒状の芯管と該芯管の外周側に配置した円筒状の外筒との間に挿入したホースの端部上に、該外筒を断面円弧状の押圧面を有する環状に配列した拡縮する複数の加締め爪により外周側から加締めることにより縮径して締結するホース継手金具の締結装置において、前記加締め爪をホース継手金具長手方向に2列に並ぶ第1加締め爪と第2加締め爪とから構成すると共に、該第1加締め爪と第2加締め爪とを周方向にずらして配置したことを特徴とする。
【0010】
上述した本発明によれば、周方向にずらした第1加締め爪と第2加締め爪とにより外筒を加締めるため、第1加締め爪間及び第2加締め爪間に隙間が生じ、その隙間が発生した部分で外筒を加締めることができない突出した部分が生じても、その部分が連続せずに分断されるため、ホースの内周面を周方向にエンドレス状に連続した部分で高い圧着力で芯管に圧着することができる。そのため、高いシール効果を発揮し、シール性の改善が可能になる。
【0011】
第1加締め爪と第2加締め爪をずらして配置するだけでよいため、ホース継手金具の構造を全く変更する必要がない。
【0012】
【発明の実施の形態】
以下、本発明の構成について添付の図面を参照しながら詳細に説明する。
【0013】
図1は本発明のホース継手金具の締結方法で使用するホース継手金具の一例をホースを接続した状態で示す半断面正面図であり、1はホース継手金具、2はホースである。
【0014】
ホース継手金具1は、金属製円筒状のニップル(芯管)3と、その外周側に配置した金属製円筒状のソケット(外筒)4を備えている。ニップル3のホース挿入側外周面3aに、周方向に環状に延在する複数の溝5がニップル3の長手方向に沿って所定の間隔で設けられ、これらの溝5に挿入されたホース2の弾性体チューブ層2Aの内周側を係止するようになっている。
【0015】
ニップル3のホース反挿入側外周面3bにはネジ部6が形成され、このネジ部6を介してホース継手金具1が機器に取り付けられる。ニップル3の中央部外周面3cには、周方向に沿って延在する環状溝7が形成され、この環状溝7にソケット4のホース反挿入側端部4aが係止している。
【0016】
ソケット4の内周面4bには、周方向に環状に延在する複数のホース把持用突起8がソケット長手方向に沿って所定の間隔で突設され、加締め時に挿入されたホース2の補強層2Bに食い込んでホース2を把持するようになっている。
【0017】
上記のホース継手金具1を締結する本発明のホース継手金具の締結装置は、図2,3に示すように、ソケット4を加締める複数の加締め爪9を備えている。加締め爪9は環状に配列され、ホース継手金具長手方向に2列に並ぶ第1加締め爪10と第2加締め爪11とから構成されている。
【0018】
第1加締め爪10と第2加締め爪11は、ソケット4を押圧する断面円弧状の押圧面10a,11aをそれぞれ内周側に有し、図3に示すように、周方向にずらした配置になっている。
【0019】
加締め爪9の一方側にクリンプリング12が配設されている。クリンプリング12の外周面に他方側に延在する円筒状のガイド筒13が固定され、このガイド筒13の内周側に中心に向けて突設された複数の加締め爪9と同数の支持アーム14が、ガイド筒13の長手方向に摺動自在に設けられている。
【0020】
各支持アーム14には、加締め時にホース継手金具1の長手方向中央部を保持する保持爪15が径方向に拡縮自在に取り付けられ、ボルト16によりホース継手金具1を保持する所定の拡縮位置に固定できるようになっている。
【0021】
各保持爪15の一方側に上記第2加締め爪11が摺動自在に取り付けられている。各第2加締め爪11は径方向に拡縮自在に配設され、不図示のスプリングにより常時開いた図2の拡張位置に附勢されている。
【0022】
各第2加締め爪11の一方側に上記第1加締め爪10が摺動自在に取り付けられている。各第1加締め爪10も、第2加締め爪11と同様に、径方向に拡縮自在に配設され、不図示のスプリングにより常時開いた図2の拡張位置に附勢されている。
【0023】
第1加締め爪10及び第2加締め爪11の外周面10b,11bはテーパー面に形成され、加締め時に図4に示すように、クリンプリング12の傾斜した内周面12aに係合するようになっている。
【0024】
保持爪15の他方側には、第1加締め爪10と第2加締め爪11を加締め作動する作動手段16が設置されている。作動手段16は、第1加締め爪10と第2加締め爪11をクリンプリング12内に押し込むための油圧シリンダ17を有し、その伸縮ロッド17aの先端にホース継手金具1の端面に突き当たる突き当て部材18がノブ19を介して固定されている。
【0025】
伸縮ロッド17aの伸長により、突き当て部材18に押されたホース継手金具1が矢印で示す方向に移動し、それ伴って移動する保持爪15と共に第1加締め爪10と第2加締め爪11がクリンプリング12内に移動し、当接するクリンプリング12の傾斜した内周面12aに押されて、第1加締め爪10と第2加締め爪11が縮径し、ソケット4を加締めるようになっている。
【0026】
以下、上述したホース継手金具締結装置を用いて、本発明のホース継手金具の締結方法を説明する。
【0027】
先ず、ニップル3のホース挿入側外周面3aとソケット4の内周面4bとの間にホース2の端部2Xを挿入した後、図2に示すように、保持爪15によりホース継手金具1を保持する。次いで、油圧シリンダ17を作動させ、突き当て部材18によりホース継手金具1を矢印で示す方向に移動させ、第1加締め爪10と第2加締め爪11をクリンプリング12内に移動させる。
【0028】
当接するクリンプリング12の傾斜した内周面12aに押されて、第1加締め爪10と第2加締め爪11が径方向に縮径し、ソケット4を外周側から加締める。これにより、図4に示すように、ソケット4が縮径してホース2の端部2X上に締結され、その結果、ソケット4がホース2の端部2Xを押圧し、ホース2をニップル3のホース挿入側外周面3a上に圧着する。
【0029】
第1加締め爪10間、及び第2加締め爪11間には、図5に示すように、隙間20,21が生じ、隙間20,21が発生した部分でソケット4を効果的に加締めることができない突出した部分4x,4yが生じるが、この部分4x,4yが第1加締め爪10と第2加締め爪11を周方向にずらして配置しているので連続せずに分断される(図1参照)。そのため、ホース2の内周面が周方向にエンドレス状に連続した部分で高い圧着力でニップル3に圧着し、従って高いシール性を発揮することができる。
【0030】
また、加締め爪9の構成を変えるだけでよいため、ホース継手金具1の設計変更が不要であり、既存のホース継手金具に対して容易に対応することができる。
【0031】
【発明の効果】
上述したように本発明は、加締め爪をホース継手金具長手方向に2列に並ぶ第1加締め爪と第2加締め爪とから構成すると共に、該第1加締め爪と第2加締め爪とを周方向にずらして配置し、その第1加締め爪と第2加締め爪によりソケットを加締めるようにしたので、ホース継手金具の構造を変更することなくシール性を向上することができる。
