Description

【0001】
【発明の属する技術分野】
本発明は、線材保持用グリップに関するものであり、特に、電線等の線材を、一対の押圧手段によって挟持する線材保持用グリップに関するものである。
【0002】
【従来の技術】
従来より、電線の先端に圧着端子を取りつける端子圧着装置として、動力機構により上下運動する圧潰部材と、凹状のアンビルが形成された基台とを備えたものが知られている。これによれば、基台のアンビルに送り込まれた圧着端子に電線の先端を挿入し、圧潰部材で圧潰することにより、電線の先端に圧着端子が取りつけられる。
【0003】
また、圧着端子を連続して取りつけることができるように、電線を送り込む電線送り機構と、電線を切断するとともに電線の端部の被覆材を除去する切断機構とを備えた端子圧着装置も知られている。これによれば、まず、電線の先端側の被覆材が切断機構によって除去され、基台のアンビル上に載置された圧着端子に電線の先端側が挿入される。そして、動力機構により圧着端子が圧潰されると、電線の先端に圧着端子が取りつけられる。その後、圧着端子が取りつけられた電線は電線送り機構により所定長さ分だけ送られ、切断機構により切断される。このように、圧潰動作が行われる毎に、圧潰後の電線の送り動作(排出動作)及び切断動作が行われ、続いて、新しく送り込む電線の被覆材除去動作及び圧着端子への送り込み動作が順次行われる。
【0004】
ところで、電線を送る際や、被覆材を除去する際には、電線を保持する必要がある。このため、上記の端子圧着装置は、保持用グリップを備えている。図8(a)は保持用グリップの正面図であり、図8(b)は保持用グリップの斜視図である。この保持用グリップ50は、電線Lを挟む一対の押圧手段51,52と、夫々の押圧手段51,52を回転させるグリップ可動機構(図示しない)とを備えている。つまり、グリップ可動機構を動作させると、紙面右側に配設された押圧手段51が軸53を中心として反時計方向に回転すると共に、紙面左側に配設された押圧手段52が軸54を中心として時計方向に回転する。これにより、電線Lは、夫々の押圧手段51,52の当接面55,56に挟まれた状態で保持される。なお、当接面55,56には複数の溝部57,58が形成されており、摩擦抵抗を大きくすることにより電線Lの滑りを防止している。
【0005】
以上の従来技術は、当業者において当然として行われているものであり、出願人は、この従来技術が記載された文献を知見していない。
【0006】
【発明が解決しようとする課題】
しかしながら、上記の保持用グリップ50では、溝部55によって、電線Lの滑りをある程度防止することができるものの、例えば電線Lの被覆材を除去する場合においては、大きな保持力が必要であるため、グリップ可動機構による締付力を大幅に増加させなければならなかった。
【0007】
ところが、大きな締付力で電線Lを挟持すると、電線Lが変形してしまい、特に、被覆材にポリテトラフルオロエチレンが使用されている電線においては、被覆材が潰れて元の形に戻らないことや、被覆材に溝部57,58の跡が残ることもあった。また、電線Lの変形により、電線Lの特性に影響を及ぼす恐れもあった。さらに、電線Lの直径が異なる場合には、保持力を調節し直す必要があり、多品種少量生産が主流となる現在の生産体制の下では、生産性を高めることが困難であった。
【0008】
そこで、本発明は、上記の実状に鑑み、電線等の線材を、滑ることなく確実に保持することができるとともに、線材を変形させることなく挟持できる線材保持用グリップの提供を課題とするものである。
【0009】
【課題を解決するための手段】
請求項1の発明にかかる線材保持用グリップは、一対の押圧手段により電線等の線材を挟持する線材保持用グリップであって、前記押圧手段は、一定の間隔で且つ前記線材の挿入方向に対して略垂直に並設された複数枚の押圧片を具備し、互いに隣合う前記押圧片同士の隙間と他方の押圧手段における押圧片とが対向するように前記一対の押圧手段が配設されているものである。
【0010】
ここで、「押圧片同士の隙間」の幅は特に限定されるものではないが、対向する押圧片(すなわち他方の押圧手段における押圧片)の板厚に一致させた場合、及び板厚よりも広くした場合には、押圧手段における押圧片の先端部分を、対向する隙間に挿入させ、互いに重ね合わせることが可能になる。特に、隙間の幅を板厚に略一致させた場合には、互いの押圧片が交互に積層された状態となり、先端部分に隙間が生じなくなる。
【0011】
請求項1の発明の線材保持用グリップによれば、一対の押圧手段によって線材を挟むと、各押圧手段における複数の押圧片の先端が線材の周面に一定の間隔で当接する。この際、一方の押圧手段における所定の押圧片と、それに対向する他方の押圧片とは、線材に対してせん断力を与えるように作用することから大きな保持力が発生する。ここで、仮に、一対(二枚)の押圧片によって線材にせん断力を与えたとした場合、線材が大きく変形したり線材が切断されたりする恐れがある。
【0012】
ところが、請求項1の発明によれば、複数枚の押圧片が一定の間隔で並設されているため、線材は複数枚の押圧片の先端部分によって直線状に保たれる。つまり、せん断力が加えられても、線材の変形が抑制されるため、線材が折れ曲ったり、切断されたりすることが防止される。しかも、複数の押圧片によって同時に挟持されることから、線材の保持力が極めて大きくなる。換言すれば、一対の押圧片による締付力が比較的小さくても十分に保持できる。そして、締付力を小さく設定した場合には、線材の潰れや変形が防止される。
【0013】
請求項2の発明にかかる線材保持用グリップは、請求項1に記載の線材保持用グリップにおいて、夫々の前記押圧片の先端には、略V字形に切欠かれた切欠部が設けられ、一対の前記押圧手段における前記押圧片の先端部分同士が重なり合った際に、前記切欠部によって形成される略四角形の開口の内周縁により、前記線材の周面が挟持されるものである。
【0014】
したがって、請求項2の発明の線材保持用グリップによれば、請求項1の発明の作用に加え、一対の押圧手段における押圧片の先端部分が互いに重なり合うと、切欠部によって開口が形成される。この開口の大きさは、一対の押圧手段の間隔、すなわち押圧片の重なり度合いによって変化する。特に、切欠部は略V字形に切欠かれていることから、開口は略四角形(菱形)となり、しかも押圧片の重なり度合いを変化させると、開口の高さ及び幅がともに変化する。したがって、線材の周面に対して、開口の内周縁を均等に圧接させることが可能になる。
【0015】
請求項3の発明にかかる線材保持用グリップは、請求項1または請求項2に記載の線材保持用グリップにおいて、夫々の前記押圧手段に連結され、リニアガイドに沿って摺動可能な一対の摺動部材と、前記一対の押圧手段の間隔を変化させるように前記一対の摺動部材を摺動させる駆動手段とをさらに備えるものである。
【0016】
ここで、「駆動手段」としては、モータと、モータの回転運動を直線運動に変化させるピニオン及びラックとを組合せたものが例示できる。
【0017】
したがって、請求項3の発明の線材保持用グリップによれば、請求項1または請求項2の発明の作用に加え、駆動手段の動力が摺動部材に伝えられ、一対の摺動部材は、リニアガイドに沿って直線上を変位する。線材の挿入及び排出が行われる工程では、一方の押圧手段と他方の押圧手段との間に空間が形成される。一方、線材を挟持する工程では、一対の押圧手段が重なり合い、各押圧片の先端が線材の周面に当接する。特に請求項2の発明において請求項3の発明を適用すると、直線上を変位することから、線材の周面に対して保持力を一層均等に加えることが可能になるとともに、変化の前後における開口の形状が略相似するため、線材の直径が異なっても、開口の内周縁を同じように当接させることが可能になる。
【0018】
【発明の実施の形態】
以下、本発明の一実施形態である線材保持用グリップについて、図1乃至図7に基づき説明する。図1は線材保持用グリップが組込まれた端子圧着装置の構成を示す斜視図、図2及び図3は端子圧着装置の動作を説明するための説明図、図4は線材保持用グリップの構成を示す斜視図、図5及び図6は押圧手段における押圧片の構成を示す拡大斜視図、図7は押圧手段の動作を説明するための説明図である。
【0019】
本実施形態の線材保持用グリップ1(以下、「グリップ1」と称す)が組込まれた端子圧着装置Aは、電線Lの送込み、被覆材の除去、圧着端子の圧潰、及び電線Lの切断を一連の動作として行い、両端に圧着端子が圧着された所定長さの電線Lを連続して製作するものである。この端子圧着装置Aは、図1に示すように、電線Lの先端側に圧着端子を圧着させる第1圧着機本体2と、電線Lの後端側に圧着端子を圧着させる第2圧着機本体3と、電線Lの先端側を第1圧着機本体2に送り込む電線送り機構4と、電線Lを切断するとともに電線Lの端部の被覆材を除去する切断機構5と、切断後の電線Lを保持し電線Lの後端側を第2圧着機本体3に送り込むチャック機構6とを備えている。そして、このチャック機構6に本発明のグリップ1が組込まれている。
【0020】
以下、各部の構成及び動作について簡単に説明する。なお、第1圧着機本体2と第2圧着機本体3とは基本的な構成が等しいため、第2圧着機本体3についての詳細な説明は省略する。第1圧着機本体2は、支柱部材8と、動力機構(図示しない)の動作により上下運動するガイド部材9と、支柱部材8の下側に位置する基台10とを備えている。
【0021】
ガイド部材9には、調節機構(図示しない)と圧力センサ11とを介して圧潰部材12が取付けられている。圧潰部材12は、ガイド部材9の下端から突出して配設されており、調節機構により下方への突出長さを調節できるようになっている。圧潰部材12は、ガイド部材9と一体となって上下運動する。
【0022】
基台10の上面には、凹状のアンビル10aが形成されている。したがって、基台10のアンビル10aに圧着端子が供給された状態で、電動機を駆動させると、圧潰部材12がガイド部材9とともに下方に移動し、圧潰部材12の先端と基台10に形成されたアンビル10aとが噛み合って、圧着端子を圧潰する。
【0023】
また、第1圧着機本体2は、圧着端子を基台10のアンビル10aに順次供給する端子搬送手段(図示しない)を備えている。端子搬送手段は、一連に繋がれた圧着端子を案内部材に沿って移動させるものであり、圧潰部材12の動作に連動している。
【0024】
電線送り機構4には、図2または図3に示すように、電線取込みガイド14、回転体15、及びガイドパイプ16が、円形板17の上に配設されている。回転体15は、モータ(図示しない)により駆動され、回転方向と回転数とを制御することにより電線Lを測長して送ることができる。電線取込みガイド14を介して取込まれた電線Lは、2つの回転体15により、ガイドパイプ16内に送り込まれ、更にガイドパイプ16の先端へと導かれる。ガイドパイプ16の先方向には、切断機構5が配設されており、回転体15より電線Lを送込むと、電線Lの先端が切断機構5の上刃と下刃との間に挿入される(図2の矢印A)。
【0025】
また、電線送り機構4の円形板17は、モータ等を有する回転手段(図示しない)により所定角度内で回転する。つまり、回転手段により円形板17が回転すると、ガイドパイプ16の先端位置が変位し(図2の矢印B)、ガイドパイプ16の先端が第1圧着機本体2のアンビル10aに臨む。この状態で、回転体15により電線Lを送込むと、電線Lの先端がアンビル10a上に載置された圧着端子の所定部位に挿入される(図2の矢印C)。
【0026】
切断機構5は、電線Lの切断や、電線Lの端部の被覆材を除去するものであり、上下方向に配設された一対の刃(上刃・下刃)と、上刃を下刃に対して上下に移動させる移動手段(図示しない)とを備えている。つまり、上刃と下刃との間に電線Lを挿入した状態で、上刃が下刃に当接するように移動手段を動作させることにより電線Lが切断される。また、電線Lの端部が所定長さ突出するように、上刃と下刃との間に電線Lを挿入した状態で、上刃と下刃との間隔が電線Lの芯線の大きさに対応した距離となるように移動手段を動作させ、続いて、電線送り機構4あるいはチャック機構6により電線Lを引っ張ることにより、電線Lの端部の被覆材が除去される。
【0027】
チャック機構6は、切断機構5の後方側に配設され、グリップ1、移動手段18、及び送込手段19を備えている。グリップ1は、送込手段19の先端に取付けられており、電線Lを挟んだ状態で保持するものである。このグリップ1の詳細な構成については後述する。移動手段18は、グリップ1が弧を描くように、グリップ1及び送込手段19を所定範囲内で回転移動させるものであり、グリップ1により電線Lが保持された状態で、電線Lの後端側を切断機構5側から第2圧着機本体3側に移動させることができる(図3の矢印D)。また、送込手段19は、グリップ1を前後方向に移動させるものであり、第2圧着機本体3のアンビル上に載置された圧着端子の所定部位に、電線Lの後端側を送り込む(図3の矢印E)とともに、圧着端子の圧潰後、圧着端子が圧着された電線Lをアンビルから排出する。なお、これらのグリップ1、移動手段18、及び送込手段19は圧縮空気の供給により駆動される。
【0028】
次に、グリップ1の構成について、図4に基づき説明する。グリップ1は、グリップ可動機構21と、一対の押圧手段22,23とを備えている。グリップ可動機構21は、押圧手段22,23を動作させるものであり、一対の押圧手段22,23の間隔を第一間隔(電線Lの挿入及び排出が可能な状態)と、第二間隔(電線Lを挟持する状態)とに切換えることができる。
【0029】
グリップ可動機構21は、直線状のリニアガイド25と、リニアガイド25に案内されて摺動する二つの摺動部材26,27と、各摺動部材26,27の前面から前方に突出するL字形の腕部28,29とを備え、腕部28,29の先端に取りつけられた押圧手段22,23を左右方向に移動可能に支持している。また、グリップ可動機構21は、二つの摺動部材26,27を夫々駆動する手段として、
リニアガイド25の裏面に固定されたベース部材30と、ベース部材30に取付けられたモータ31と、モータ31の回転軸に嵌合されたピニオン(図示しない)と、ピニオンに歯合された一対のラック(図示しない)と、夫々のラック及び摺動部材26,27を連結する連結部材32とを備えている。つまり、モータ31の駆動によりピニオンが回転すると、ピニオンに歯合する一対のラックが相反方向に変位し、摺動部材26,27同士の間隔が変化する。ここで、モータ31、ピニオン、ラック、及び連結部材32を組合せたものが本発明の駆動手段に相当する。
【0030】
押圧手段22は、図5に示すように、一対の外側押圧片34と、これらの間に所定の間隔で配設された複数枚の内側押圧片35と、隣合う内側押圧片35同士を一定の間隔に保つスペーサ36とから構成されている。なお、本例では、内側押圧片35の板厚が約0.45mm、各押圧片34,35同士の隙間が約0.5mmになるように設定されている。外側押圧片34及び内側押圧片35は、いずれも略長方形状を呈しているが、その先端37には略V字形に切欠かれた切欠部38が設けられている。なお、切欠部38の大きさは全ての押圧片34,35において等しく、夫々の先端37は連続する切断面となっている。ここで、外側押圧片34及び内側押圧片35が本発明の押圧片に相する。
【0031】
一方、押圧手段23は、図6に示すように、一対の外側押圧片40と、これらの間に所定の間隔で配設された複数枚の内側押圧片41と、隣合う内側押圧片41同士の間隔を一定に保つスペーサ42とから構成されている。また、内側押圧片41の板厚が約0.45mm、各押圧片40,41同士の隙間が約0.5mmになるように設定されている。なお、内側押圧片41は、押圧手段22の内側押圧片35と略同じ形状となっているが、外側押圧片40は、押圧手段22の外側押圧片34に比べ、下方に延出された形状になっている。外側押圧片40及び内側押圧片41の先端43には略V字形に切欠かれた切欠部44が設けられている。ここで、外側押圧片40及び内側押圧片41が本発明の押圧片に相当する。
【0032】
これらの押圧手段22及び押圧手段23は、切欠部38と切欠部44とが対向し、且つ電線Lの挿入方向に対して各押圧片34,35,40,41が略垂直になるように配設されている。特に、押圧手段22における外側押圧片34及び内側押圧片35が、押圧手段23における各押圧片40,41同士の隙間に、夫々対向するように配設されている。すなわち、押圧手段22と押圧手段23とを比較した場合、内側押圧片35と内側押圧片41との板厚は同一であり、隣合う内側押圧片35同士の隙間と隣合う内側押圧片41同士の隙間とが同一の寸法であることから、夫々の押圧片34,35,41はいずれも、他方の押圧手段22,23の隙間に対向した状態で配設されている。しかも、各押圧片34,35,41の板厚(例えば約0.45mm)は、隙間の寸法(例えば約0.5mm)より僅かに薄いため、押圧手段22及び押圧手段23を接近させると、図7(b)に示すように、夫々の押圧片34,35,41が対向する隙間に挿入され、互いに重ね合わされる。特に、各押圧片34,35,41の板厚と隙間との寸法差は極僅かであるため、重ね合わされた部分は、交互に積層された状態となる。
【0033】
次に、グリップ1による電線Lの保持動作について図4及び図7に基づき説明する。電線Lがグリップ1に送り込まれ、運転制御手段(図示しない)から電線Lを保持させる指示信号が送信されると、モータ31が駆動しピニオンが回転する。ピニオンの回転により一対のラックが相反方向に変位し、摺動部材26,27をリニアガイド25に沿って摺動させる。
【0034】
すると、摺動部材26,27に接続された二つの押圧手段22,23が互いに接近し、その後、押圧手段22における外側押圧片34及び内側押圧片35と、押圧手段23における外側押圧片40及び内側押圧片41とが互いに重なり合う。各押圧片34,35,40,41の先端37,43には、V字形の切欠部38,44が形成されているため、各押圧片34,35,40,41が互いに重なり合うと、図7(a)に示すように、切欠部38,44によって略正方形(菱形)の開口45が形成され、その開口45に電線Lが挿通された状態となる。そして、開口45の内周縁45aが電線Lの直径に一致すると、全ての内周縁45aが電線Lの周面に当接する。すなわち、モータ31によって押圧手段22,23同士を重なり合う方向に付勢することにより、開口45の内周縁45aを電線Lの周面に圧接させ、電線Lを挟持することが可能になる。
【0035】
特に、本例の切欠部38,44はV字形であり、しかも押圧手段22,23同士の重なり度合いを直線状に変化させるため、開口45は正方形の形状を維持したまま大きさが変化する。したがって、電線Lの直径が異なっても、電線Lの周面に対して開口45の内周縁45aを均等に圧接させることができる。
【0036】
また、図7(b)に示すように、電線Lが挟持される場合には、並設された複数枚の押圧片34,35,40,41の切欠部38,41が、電線Lの周面に同時に当接する。ここで、各押圧片34,35,40,41は交互に配置されているため、電線Lの周面には、所定の間隔で複数のせん断力が加わり、これにより大きな保持力が発生する。換言すれば、電線Lの単位面積当りの保持力が比較的小さくても、複数のせん断力により十分な保持力を得ることができる。しかも、隣合う押圧片34,35,40,41同士の間隔が極めて狭いことから、せん断力が加えられているにも拘わらず、電線Lは各押圧片34,35,40,41の先端37,43によって直線状態を保つように支持される。
【0037】
このように、上記のグリップ1では、複数のせん断力を合わせた極めて大きな保持力により、電線Lを確実に保持することができる。しかも、電線Lは各押圧片34,35,40,41の先端37,43によって直線状に支持されるため、変形させることなく保持することができる。また、変形が抑制されることから、線材の直径が変わるごとの微調整が不要となり、調整作業の煩雑化を防止できる。特に、電線Lの被覆材としてポリテトラフルオロエチレンを使用する場合であっても、被覆材が潰れたり、被覆材に跡が残るようなことはない。
【0038】
また、上記のグリップ1では、切欠部38,44の重ね合わせにより、略正方形の開口45が形成されるため、断面円形の電線Lに対して、開口45の内周縁45aを均等に当接させ電線Lの周面を確実に挟持することができる。つまり、電線Lの変形及び傷付きを確実に防止することができる。また、加工される電線Lの直径が変わっても容易に対応させることができる。
【0039】
以上、本発明について好適な実施形態を挙げて説明したが、本発明はこれらの実施形態に限定されるものではなく、以下に示すように、本発明の要旨を逸脱しない範囲において、種々の改良及び設計の変更が可能である。
【0040】
すなわち、上記のグリップ1では、一対の押圧手段22,23の間隔を変更させる際、一対の押圧手段22,23を直線状に変位させるものを示したが、従来のように一対の押圧手段を互いに回動させることにより、間隔を変更するようにしてもよい。この場合、リニアガイド25及び摺動部材26,27の代わりに、各押圧手段を回動可能に支持する軸部材が設けられる。但し、本例のようにリニアガイド25に沿って直線状に変位させるようにすれば、押圧片34,35,40,41の板厚と、それに対向する隙間の寸法とを略一致させた場合でも、精度よく嵌合せることができる。しかも、押圧手段22及び押圧手段23の重ね合わせ度合いに拘わらず、開口35を正方形状に保つことができ、電線Lの種類が変わっても電線Lの周面を均等な圧力で挟持することができる。
【0041】
上記のグリップ1では、線材として電線Lを示したが、電線に代えて、鉄筋やパイプ等を保持するようにしてもよい。また、この場合、線材の太さや硬度は特に制限されることはない。
【0042】
【発明の効果】
以上のように、請求項1の発明の線材保持用グリップは、複数のせん断力を合わせた極めて大きな保持力により、線材を確実に保持することができる。しかも、線材は各押圧片の先端部分によって支持されるため、変形させることなく保持することができる。また、変形が抑制されることから、線材の直径が変わるごとの微調整が不要となり、調整作業の煩雑化を防止できる。
【0043】
請求項2の発明の線材保持用グリップは、請求項1の発明の効果に加えて、開口が略四角形であるため、断面円形の線材に対して、開口の内周縁を均等に当接させ線材の周面を確実に挟持することができる。つまり、線材の変形及び傷付きを一層防止することができる。また、線材の直径が変わっても容易に対応させることができる。
【0044】
請求項3の発明の線材保持用グリップは、請求項1または請求項2の発明の効果に加えて、線材の周面を、一層均等な保持力で挟持することが可能となり、線材の変形を確実に防止することができる。また、リニアガイドに沿って直線的に移動することから、一方の押圧手段における押圧片の隙間と、他方の押圧手段における押圧片の板厚を略一致させた場合でも、精度よく嵌め合せることができる。そして、この場合、重ねられた押圧片同士の間に隙間が殆ど形成されないことから、挟持の際における線材の撓みを確実に防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wire holding grip, and more particularly to a wire holding grip for holding a wire such as an electric wire by a pair of pressing means.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a terminal crimping device for attaching a crimp terminal to the end of an electric wire, a device including a crushing member that moves up and down by a power mechanism and a base on which a concave anvil is formed is known. According to this, the tip of the electric wire is inserted into the crimp terminal sent to the anvil of the base and crushed by the crushing member, so that the crimp terminal is attached to the tip of the electric wire.
[0003]
Also known is a terminal crimping device provided with a wire feeding mechanism for feeding an electric wire and a cutting mechanism for cutting the electric wire and removing a covering material at an end of the electric wire so that the crimp terminal can be continuously attached. ing. According to this, first, the covering material on the distal end side of the electric wire is removed by the cutting mechanism, and the distal end side of the electric wire is inserted into the crimp terminal mounted on the anvil of the base. When the crimp terminal is crushed by the power mechanism, the crimp terminal is attached to the end of the electric wire. After that, the wire to which the crimp terminal is attached is sent by a predetermined length by the wire feed mechanism and cut by the cutting mechanism. As described above, every time the crushing operation is performed, the feeding operation (discharging operation) and the cutting operation of the crushed electric wire are performed, and subsequently, the covering material removing operation of the newly transmitted electric wire and the feeding operation to the crimp terminal are sequentially performed. Done.
[0004]
By the way, when sending an electric wire or removing a covering material, it is necessary to hold the electric wire. For this reason, the above-mentioned terminal crimping device is provided with a holding grip. FIG. 8A is a front view of the holding grip, and FIG. 8B is a perspective view of the holding grip. The holding grip 50 includes a pair of pressing means 51 and 52 for sandwiching the electric wire L, and a grip moving mechanism (not shown) for rotating the respective pressing means 51 and 52. That is, when the grip movable mechanism is operated, the pressing means 51 disposed on the right side of the paper rotates counterclockwise about the shaft 53, and the pressing means 52 disposed on the left side of the paper rotates about the shaft 54. Rotate clockwise. Thus, the electric wire L is held in a state of being sandwiched between the contact surfaces 55 and 56 of the respective pressing means 51 and 52. A plurality of grooves 57, 58 are formed in the contact surfaces 55, 56, and the sliding of the electric wire L is prevented by increasing the frictional resistance.
[0005]
The above prior art is naturally performed by those skilled in the art, and the applicant does not know the document describing this prior art.
[0006]
[Problems to be solved by the invention]
However, in the above-described holding grip 50, although the sliding of the electric wire L can be prevented to some extent by the groove portion 55, a large holding force is required, for example, when removing the covering material of the electric wire L. The tightening force of the movable mechanism had to be greatly increased.
[0007]
However, when the electric wire L is pinched with a large clamping force, the electric wire L is deformed. In particular, in the electric wire in which polytetrafluoroethylene is used for the coating material, the coating material is crushed and does not return to the original shape. In some cases, traces of the grooves 57 and 58 may remain on the coating material. In addition, the deformation of the electric wire L may affect the characteristics of the electric wire L. Furthermore, when the diameter of the electric wire L is different, it is necessary to readjust the holding force, and it is difficult to increase the productivity under the current production system in which multi-product small-quantity production is mainstream.
[0008]
In view of the above situation, an object of the present invention is to provide a wire holding grip that can securely hold a wire such as an electric wire without slipping and that can hold the wire without deforming the wire. is there.
[0009]
[Means for Solving the Problems]
The wire holding grip according to the invention of claim 1 is a wire holding grip for holding a wire such as an electric wire by a pair of pressing means, wherein the pressing means are arranged at regular intervals and in a direction in which the wire is inserted. A plurality of pressing pieces arranged substantially vertically side by side, and the pair of pressing means is disposed so that a gap between the pressing pieces adjacent to each other and a pressing piece in the other pressing means face each other. Is what it is.
[0010]
Here, the width of the “gap between the pressing pieces” is not particularly limited, but is equal to the thickness of the opposing pressing piece (that is, the pressing piece of the other pressing means), and In the case of widening, it is possible to insert the distal end portions of the pressing pieces of the pressing means into the gaps facing each other and to overlap each other. In particular, when the width of the gap is substantially equal to the plate thickness, the pressing pieces are alternately stacked, and no gap is generated at the tip end.
[0011]
According to the wire holding grip of the present invention, when the wire is sandwiched by the pair of pressing means, the tips of the plurality of pressing pieces of each pressing means abut on the peripheral surface of the wire at a constant interval. At this time, the predetermined pressing piece of one pressing means and the other pressing piece opposing it act to apply a shear force to the wire, so that a large holding force is generated. Here, if it is assumed that a shear force is applied to the wire by a pair (two) of pressing pieces, the wire may be greatly deformed or the wire may be cut.
[0012]
However, according to the first aspect of the present invention, since the plurality of pressing pieces are arranged side by side at a constant interval, the wire is kept linear by the tip portions of the plurality of pressing pieces. That is, even if a shear force is applied, the deformation of the wire is suppressed, so that the wire is prevented from being bent or cut. In addition, since the holding member is simultaneously held by the plurality of pressing pieces, the holding force of the wire becomes extremely large. In other words, even if the tightening force by the pair of pressing pieces is relatively small, it can be sufficiently maintained. When the tightening force is set small, the wire is prevented from being crushed or deformed.
[0013]
A wire holding grip according to a second aspect of the present invention is the wire holding grip according to the first aspect, wherein a notch portion cut out in a substantially V shape is provided at a tip of each of the pressing pieces. The peripheral surface of the wire is sandwiched by the inner peripheral edge of the substantially rectangular opening formed by the notch when the tip portions of the pressing pieces in the pressing means overlap each other.
[0014]
Therefore, according to the wire rod holding grip of the invention of claim 2, in addition to the operation of the invention of claim 1, when the tip portions of the pressing pieces of the pair of pressing means overlap with each other, an opening is formed by the notch. The size of the opening changes depending on the interval between the pair of pressing means, that is, the degree of overlap of the pressing pieces. In particular, since the notch is cut in a substantially V-shape, the opening is substantially square (rhombic), and when the degree of overlap of the pressing pieces is changed, both the height and width of the opening change. Therefore, the inner peripheral edge of the opening can be uniformly pressed against the peripheral surface of the wire.
[0015]
A wire holding grip according to a third aspect of the present invention is the wire holding grip according to the first or second aspect, wherein the pair of slides are connected to the respective pressing means and slidable along a linear guide. It further includes a moving member, and a driving unit that slides the pair of sliding members so as to change an interval between the pair of pressing units.
[0016]
Here, as the "driving means", a combination of a motor, a pinion and a rack for changing the rotational motion of the motor into a linear motion can be exemplified.
[0017]
Therefore, according to the wire holding grip of the invention of claim 3, in addition to the operation of the invention of claim 1 or 2, the power of the driving means is transmitted to the sliding members, and the pair of sliding members are linear. Displace on a straight line along the guide. In the step of inserting and discharging the wire, a space is formed between one pressing means and the other pressing means. On the other hand, in the step of holding the wire, the pair of pressing means overlap, and the tip of each pressing piece abuts on the peripheral surface of the wire. In particular, when the invention of claim 3 is applied to the invention of claim 2, since the displacement is performed on a straight line, the holding force can be more uniformly applied to the peripheral surface of the wire, and the opening before and after the change can be obtained. Are substantially similar to each other, so that even if the diameters of the wires are different, the inner peripheral edges of the openings can be abutted in the same manner.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a wire holding grip according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. 1 is a perspective view showing the configuration of a terminal crimping device incorporating a wire holding grip, FIGS. 2 and 3 are explanatory views for explaining the operation of the terminal crimping device, and FIG. 4 is a diagram showing the configuration of the wire holding grip. 5 and 6 are enlarged perspective views showing the configuration of the pressing piece in the pressing means, and FIG. 7 is an explanatory view for explaining the operation of the pressing means.
[0019]
The terminal crimping device A in which the wire holding grip 1 (hereinafter, referred to as “grip 1”) of the present embodiment is incorporated, feeds the wire L, removes the covering material, crushes the crimp terminal, and cuts the wire L. Are performed as a series of operations to continuously produce a wire L of a predetermined length with crimp terminals crimped on both ends. As shown in FIG. 1, the terminal crimping apparatus A includes a first crimping machine main body 2 for crimping a crimping terminal to the front end side of an electric wire L and a second crimping machine main body for crimping a crimping terminal to a rear end side of the electric wire L. 3, a wire feeding mechanism 4 for feeding the front end side of the wire L to the first crimping machine main body 2, a cutting mechanism 5 for cutting the wire L and removing a coating material on the end of the wire L, and a wire L after cutting. And a chuck mechanism 6 for feeding the rear end side of the electric wire L to the second crimping machine main body 3. The grip 1 of the present invention is incorporated in the chuck mechanism 6.
[0020]
Hereinafter, the configuration and operation of each unit will be briefly described. In addition, since the first crimping machine main body 2 and the second crimping machine main body 3 have the same basic configuration, a detailed description of the second crimping machine main body 3 is omitted. The first crimping machine main body 2 includes a support member 8, a guide member 9 that moves up and down by the operation of a power mechanism (not shown), and a base 10 located below the support member 8.
[0021]
A crushing member 12 is attached to the guide member 9 via an adjustment mechanism (not shown) and a pressure sensor 11. The crushing member 12 is disposed so as to protrude from the lower end of the guide member 9, and the length of the crushing member 12 protruding downward can be adjusted by an adjusting mechanism. The crushing member 12 moves up and down integrally with the guide member 9.
[0022]
On the upper surface of the base 10, a concave anvil 10a is formed. Therefore, when the electric motor is driven in a state where the crimp terminal is supplied to the anvil 10 a of the base 10, the crushing member 12 moves downward together with the guide member 9 and is formed on the tip of the crushing member 12 and the base 10. The crimp terminal is crushed by meshing with the anvil 10a.
[0023]
Further, the first crimping machine main body 2 is provided with terminal transport means (not shown) for sequentially supplying crimp terminals to the anvil 10a of the base 10. The terminal transport means moves the crimp terminals connected in series along the guide member, and is linked to the operation of the crushing member 12.
[0024]
As shown in FIG. 2 or FIG. 3, the electric wire feeding mechanism 4 has an electric wire intake guide 14, a rotating body 15, and a guide pipe 16 disposed on a circular plate 17. The rotating body 15 is driven by a motor (not shown), and can measure and send the electric wire L by controlling the rotating direction and the number of rotations. The electric wire L taken in through the electric wire taking-in guide 14 is sent into the guide pipe 16 by the two rotating bodies 15, and further guided to the tip of the guide pipe 16. The cutting mechanism 5 is provided in the forward direction of the guide pipe 16. When the electric wire L is sent from the rotating body 15, the tip of the electric wire L is inserted between the upper blade and the lower blade of the cutting mechanism 5. (Arrow A in FIG. 2).
[0025]
Further, the circular plate 17 of the electric wire feeding mechanism 4 is rotated within a predetermined angle by rotating means (not shown) having a motor or the like. In other words, when the circular plate 17 is rotated by the rotating means, the tip of the guide pipe 16 is displaced (arrow B in FIG. 2), and the tip of the guide pipe 16 faces the anvil 10a of the first crimping machine main body 2. In this state, when the electric wire L is sent by the rotating body 15, the tip of the electric wire L is inserted into a predetermined portion of the crimp terminal mounted on the anvil 10a (arrow C in FIG. 2).
[0026]
The cutting mechanism 5 is for cutting the electric wire L and removing the covering material at the end of the electric wire L, and a pair of blades (upper blade / lower blade) arranged vertically and a lower blade And moving means (not shown) for moving up and down. That is, in a state where the electric wire L is inserted between the upper blade and the lower blade, the electric wire L is cut by operating the moving means so that the upper blade comes into contact with the lower blade. Further, with the wire L inserted between the upper blade and the lower blade so that the end of the wire L projects a predetermined length, the distance between the upper blade and the lower blade is set to the size of the core wire of the wire L. The moving means is operated so as to have the corresponding distance, and subsequently, the wire L is pulled by the wire feed mechanism 4 or the chuck mechanism 6, whereby the covering material at the end of the wire L is removed.
[0027]
The chuck mechanism 6 is disposed on the rear side of the cutting mechanism 5 and includes the grip 1, the moving unit 18, and the feeding unit 19. The grip 1 is attached to the leading end of the feeding means 19 and holds the electric wire L in a state of being sandwiched therebetween. The detailed configuration of the grip 1 will be described later. The moving means 18 is for rotating the grip 1 and the feeding means 19 within a predetermined range so that the grip 1 draws an arc, and the rear end of the electric wire L in a state where the electric wire L is held by the grip 1. The side can be moved from the cutting mechanism 5 side to the second crimping machine main body 3 side (arrow D in FIG. 3). Further, the feeding means 19 is for moving the grip 1 in the front-rear direction, and feeds the rear end side of the electric wire L to a predetermined portion of the crimp terminal placed on the anvil of the second crimping machine main body 3 ( After the crush of the crimp terminal together with the arrow E) in FIG. 3, the wire L to which the crimp terminal is crimped is discharged from the anvil. The grip 1, the moving means 18 and the feeding means 19 are driven by supplying compressed air.
[0028]
Next, the configuration of the grip 1 will be described with reference to FIG. The grip 1 includes a grip movable mechanism 21 and a pair of pressing means 22 and 23. The grip movable mechanism 21 operates the pressing units 22 and 23, and sets the interval between the pair of pressing units 22 and 23 to a first interval (a state where the wire L can be inserted and ejected) and a second interval (the wire L). L).
[0029]
The grip movable mechanism 21 includes a linear linear guide 25, two sliding members 26 and 27 that are guided and slid by the linear guide 25, and an L-shape that projects forward from the front surface of each of the sliding members 26 and 27. And pressing means 22, 23 attached to the tips of the arms 28, 29 so as to be movable in the left-right direction. In addition, the grip movable mechanism 21 serves as means for driving the two sliding members 26 and 27, respectively.
A base member 30 fixed to the back surface of the linear guide 25, a motor 31 attached to the base member 30, a pinion (not shown) fitted to a rotation shaft of the motor 31, and a pair of gears meshed with the pinion A rack (not shown) and a connecting member 32 for connecting the respective racks and sliding members 26 and 27 are provided. That is, when the pinion is rotated by the drive of the motor 31, the pair of racks meshing with the pinion are displaced in opposite directions, and the interval between the sliding members 26 and 27 changes. Here, a combination of the motor 31, the pinion, the rack, and the connecting member 32 corresponds to the driving means of the present invention.
[0030]
As shown in FIG. 5, the pressing means 22 holds a pair of outer pressing pieces 34, a plurality of inner pressing pieces 35 disposed at a predetermined interval therebetween, and a pair of adjacent inner pressing pieces 35. And a spacer 36 maintained at an interval. In this example, the thickness of the inner pressing piece 35 is set to about 0.45 mm, and the gap between the pressing pieces 34 and 35 is set to about 0.5 mm. Each of the outer pressing piece 34 and the inner pressing piece 35 has a substantially rectangular shape, and a notch portion 38 cut out in a substantially V-shape is provided at the tip 37 thereof. In addition, the size of the notch 38 is the same in all the pressing pieces 34 and 35, and the respective leading ends 37 are continuous cut surfaces. Here, the outer pressing piece 34 and the inner pressing piece 35 correspond to the pressing piece of the present invention.
[0031]
On the other hand, as shown in FIG. 6, the pressing means 23 includes a pair of outer pressing pieces 40, a plurality of inner pressing pieces 41 disposed at a predetermined interval therebetween, and adjacent inner pressing pieces 41. Are kept constant. The thickness of the inner pressing piece 41 is set to about 0.45 mm, and the gap between the pressing pieces 40 and 41 is set to about 0.5 mm. The inner pressing piece 41 has substantially the same shape as the inner pressing piece 35 of the pressing means 22, but the outer pressing piece 40 has a shape that extends downward as compared to the outer pressing piece 34 of the pressing means 22. It has become. The outer pressing piece 40 and the inner pressing piece 41 are provided with a notch 44 at the tip 43 of the V-shaped cutout. Here, the outer pressing piece 40 and the inner pressing piece 41 correspond to the pressing piece of the present invention.
[0032]
The pressing means 22 and the pressing means 23 are arranged such that the notch 38 and the notch 44 face each other, and the pressing pieces 34, 35, 40, 41 are substantially perpendicular to the insertion direction of the electric wire L. Is established. In particular, the outer pressing piece 34 and the inner pressing piece 35 of the pressing means 22 are disposed so as to face the gaps between the pressing pieces 40 and 41 of the pressing means 23, respectively. That is, when the pressing means 22 and the pressing means 23 are compared, the thicknesses of the inner pressing pieces 35 and the inner pressing pieces 41 are the same, and the gap between the adjacent inner pressing pieces 35 and the adjacent inner pressing pieces 41 Are the same size, the respective pressing pieces 34, 35, 41 are arranged in a state of facing the gaps of the other pressing means 22, 23, respectively. Moreover, since the plate thickness (for example, about 0.45 mm) of each of the pressing pieces 34, 35, and 41 is slightly thinner than the dimension of the gap (for example, about 0.5 mm), when the pressing means 22 and the pressing means 23 are brought closer, As shown in FIG. 7B, the respective pressing pieces 34, 35, 41 are inserted into opposing gaps and overlap each other. In particular, since the dimensional difference between the plate thickness and the gap of each of the pressing pieces 34, 35, 41 is extremely small, the overlapped portions are alternately stacked.
[0033]
Next, the holding operation of the electric wire L by the grip 1 will be described with reference to FIGS. When the electric wire L is fed into the grip 1 and an instruction signal for holding the electric wire L is transmitted from an operation control means (not shown), the motor 31 is driven and the pinion is rotated. The rotation of the pinion displaces the pair of racks in opposite directions, and slides the sliding members 26 and 27 along the linear guide 25.
[0034]
Then, the two pressing means 22 and 23 connected to the sliding members 26 and 27 approach each other, and thereafter, the outer pressing piece 34 and the inner pressing piece 35 of the pressing means 22, the outer pressing piece 40 and the The inner pressing pieces 41 overlap each other. Since V-shaped notches 38, 44 are formed at the tips 37, 43 of the pressing pieces 34, 35, 40, 41, when the pressing pieces 34, 35, 40, 41 overlap with each other, FIG. As shown in FIG. 7A, a substantially square (rhombic) opening 45 is formed by the notches 38 and 44, and the electric wire L is inserted into the opening 45. When the inner peripheral edge 45a of the opening 45 matches the diameter of the electric wire L, all the inner peripheral edges 45a come into contact with the peripheral surface of the electric wire L. That is, the pressing means 22 and 23 are urged by the motor 31 in the overlapping direction so that the inner peripheral edge 45a of the opening 45 is pressed against the peripheral surface of the electric wire L and the electric wire L can be clamped.
[0035]
In particular, the cutouts 38 and 44 in this example are V-shaped, and since the degree of overlap between the pressing means 22 and 23 is changed linearly, the size of the opening 45 changes while maintaining the square shape. Therefore, even if the diameter of the electric wire L is different, the inner peripheral edge 45a of the opening 45 can be uniformly pressed against the peripheral surface of the electric wire L.
[0036]
As shown in FIG. 7B, when the electric wire L is sandwiched, the notches 38, 41 of the plurality of pressing pieces 34, 35, 40, 41 arranged in parallel form the periphery of the electric wire L. Contact the surface at the same time. Here, since the pressing pieces 34, 35, 40, and 41 are alternately arranged, a plurality of shearing forces are applied to the peripheral surface of the electric wire L at a predetermined interval, thereby generating a large holding force. In other words, even if the holding force per unit area of the electric wire L is relatively small, a sufficient holding force can be obtained by a plurality of shearing forces. Moreover, since the interval between the adjacent pressing pieces 34, 35, 40, 41 is extremely narrow, the electric wire L is connected to the distal end 37 of each pressing piece 34, 35, 40, 41 despite the shearing force being applied. , 43 so as to maintain a linear state.
[0037]
As described above, in the grip 1 described above, the electric wire L can be reliably held by an extremely large holding force combining a plurality of shearing forces. Moreover, since the wire L is linearly supported by the tips 37, 43 of the pressing pieces 34, 35, 40, 41, it can be held without being deformed. Further, since the deformation is suppressed, fine adjustment is not required every time the diameter of the wire is changed, and the adjustment work can be prevented from being complicated. In particular, even when polytetrafluoroethylene is used as the covering material of the electric wire L, the covering material is not crushed or remains on the covering material.
[0038]
Further, in the grip 1, since the notch portions 38 and 44 are overlapped to form the substantially square opening 45, the inner peripheral edge 45a of the opening 45 is evenly brought into contact with the electric wire L having a circular cross section. The peripheral surface of the electric wire L can be reliably held. That is, deformation and damage of the electric wire L can be reliably prevented. Further, even if the diameter of the electric wire L to be processed changes, it can be easily handled.
[0039]
As described above, the present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to these embodiments, and various improvements can be made without departing from the gist of the present invention as described below. And design changes are possible.
[0040]
That is, in the grip 1, the pair of pressing units 22 and 23 are linearly displaced when the distance between the pair of pressing units 22 and 23 is changed. The intervals may be changed by rotating each other. In this case, instead of the linear guide 25 and the sliding members 26 and 27, a shaft member that rotatably supports each pressing unit is provided. However, if the plate is displaced linearly along the linear guide 25 as in this example, the plate thicknesses of the pressing pieces 34, 35, 40, and 41 and the dimensions of the gaps facing the pressing pieces are substantially matched. However, they can be fitted with high accuracy. Moreover, regardless of the degree of overlap of the pressing means 22 and the pressing means 23, the opening 35 can be maintained in a square shape, and even if the type of the electric wire L changes, the peripheral surface of the electric wire L can be clamped with a uniform pressure. it can.
[0041]
In the above-described grip 1, the electric wire L is shown as a wire, but instead of the electric wire, a reinforcing rod, a pipe, or the like may be held. In this case, the thickness and hardness of the wire are not particularly limited.
[0042]
【The invention's effect】
As described above, the wire holding grip according to the first aspect of the present invention can reliably hold the wire by an extremely large holding force that combines a plurality of shearing forces. Moreover, since the wire is supported by the tip of each pressing piece, it can be held without being deformed. Further, since the deformation is suppressed, fine adjustment is not required every time the diameter of the wire is changed, and the adjustment work can be prevented from being complicated.
[0043]
According to the wire holding grip of the second aspect, in addition to the effect of the first aspect, since the opening is substantially rectangular, the inner peripheral edge of the opening is evenly brought into contact with the wire having a circular cross section. Can be securely clamped. That is, the deformation and damage of the wire can be further prevented. Further, even if the diameter of the wire changes, it can be easily handled.
[0044]
According to the wire holding grip of the invention of claim 3, in addition to the effect of the invention of claim 1 or 2, the peripheral surface of the wire can be clamped with a more uniform holding force, and the deformation of the wire can be reduced. It can be reliably prevented. In addition, since the pressure member moves linearly along the linear guide, even when the gap between the pressing pieces in one pressing means and the plate thickness of the pressing pieces in the other pressing means substantially match, the fitting can be performed accurately. it can. Further, in this case, since a gap is hardly formed between the stacked pressing pieces, it is possible to reliably prevent the bending of the wire at the time of clamping.
