[1―1.回転ツール]
まず、第一実施形態に係る回転ツールの構成を説明する。図1及び図2に示すように、本実施形態に係る回転ツール1は、被接合部材2(図6参照)の摩擦攪拌接合を行う接合装置3に用いられるものであって、被接合部材2の突合せ部に回転しながら挿入される。かかる回転ツール1は、本体部10、攪拌部材50、弾性部材70、及び規制部材100を備えている。
本体部10は、例えばマシニングセンタ等の接合装置3に固定される部分であって、固定部11と、回転軸12とを備えている。固定部11は、接合装置3に取り付けられて固定される部位であり、円筒形状を呈している。固定部11はチャック機構であり、接合装置3に設けられた対となるチャック機構と協働することで、固定部11を接合装置3に対して着脱可能に固定することができる。チャック機構としては、例えば、固定部11に設けられた溝と、接合装置3に設けられて、固定部11側の溝に嵌合して挟み付ける爪とが挙げられる。固定部11の接合装置3に取り付けられる側とは他端側(図1中、下側)に、回転軸12が連結して設けられている。回転軸12は、円柱形状を呈している。回転軸12は、接合装置3からの回転力を攪拌部材50に伝達する部位であり、固定部11を介して接合装置3の回転軸(図示せず)に連結されている。
ホルダ21は、回転軸12に取り付けられ、回転軸12と同期回転し、スライド軸31及び攪拌部材50を支持する部位である。ホルダ21は、基端部(接合装置3側端部:図1中、上端部)に底部24を有する有底円筒形状(中空筒状)を呈しており、内部の中空部が、スライド軸31が挿入される収納凹部22となっている。収納凹部22は、円柱形状を呈しており、回転軸12の軸方向の先端側(図1中、下端部)が開口している。ホルダ21の円筒胴部には、キー溝23が形成されている。キー溝23は、回転軸12の軸方向(図1中、上下方向)に沿って長尺の長円形に形成されており、ホルダ21の外周面から内周面まで貫通している。なお、キー溝23は、円筒胴部を貫通していなくてもよく、円筒胴部の内周面に溝状に形成されていてもよい。キー溝23は、円筒胴部の円周方向に180°間隔で配置され、互いに対向して2か所に形成されている。なお、キー溝23の個数は、2個に限定されるものではなく、1個であってもよいし、3個以上であってもよい。
スライド軸31は、ホルダ21の収納凹部22に、回転軸方向(図1中、上下方向)にスライド可能に収納されるとともに、ホルダ21と同期回転(共回り)する部位である。スライド軸31は、円柱形状を呈しており、収納凹部22に収納可能な外径を有している。スライド軸31の外周面には、外側に突出するキー32が設けられている。キー32は、キー溝23に相当する位置に固定されており、キー溝23に挿入されている。キー32は、回転軸方向に長い長円形状を呈しており、キー溝23と同等の幅寸法を備えるとともに、キー溝23の長手方向寸法よりも短い長さ寸法を備えている。つまり、キー32は、キー溝23の幅方向に嵌合するとともに長手方向に移動可能である。なお、キー32の形状は、長円形状に限定されるものではなく、キー溝23と同等の幅寸法を備えていれば、円形や楕円形、長楕円、長方形等の他の形状であってもよい。スライド軸31の先端部(接合装置3から離間する側の端部:図1中、下端部)には、攪拌部材50が一体的に設けられている。したがって、攪拌部材50は、弾性部材70によって先端側に付勢されることによって、スライド軸31の先端側(接合装置3から離間する側:図1中、下側)に付勢される。
攪拌部材50は、本体部10からの回転力を受けて回転可能に設けられるとともに、回転軸12の軸方向に対して移動可能に本体部10に設けられる部位である。攪拌部材50は、攪拌ピン51とショルダ61とを備えている。攪拌部材50は、例えば工具鋼にて構成されている。本実施形態では、攪拌ピン51とショルダ61とが一体形成されており、コンベンショナル型の攪拌部材50となっている。攪拌部材50は、スライド軸31と一体形成されている。よって、攪拌部材50は、スライド軸31と同期回転するとともに、スライド軸31のスライド移動によって、回転軸12の軸方向に移動する。
弾性部材70は、回転軸12の軸方向に対して攪拌ピン51とショルダ61とを備えた攪拌部材50を先端側に向けて付勢する部位である。弾性部材70は、例えばコイルばねにて構成されている。弾性部材70は、ホルダ21の内部に収容され、スライド軸31の基端部31bと、ホルダ21の基端側の底部24との間に装着されている。弾性部材70は、攪拌部材50側から受ける力に対して、攪拌部材50を先端側に向けて付勢できるようになっている。
規制部材(遊嵌規制部材)100は、図1等に示すように、攪拌部材50が、所定の範囲を超えて回転軸12の基端側へ移動することを規制する部材である。規制部材100は、本実施形態では、ホルダ21の内部において、弾性部材70の中空部に遊嵌状態で配置されている。規制部材100は、摩擦攪拌接合時の反力に耐え得るように、金属、樹脂、ゴム等であって比較的硬質の材料で形成されている。規制部材100は、本実施形態では、円柱状を呈するが、配置場所の形状に合わせて適宜形成すればよい。規制部材100は、攪拌部材50の移動に伴って弾性部材70に生じる変形量が、弾性部材70の最大たわみ量(最大許容量)を超えないように攪拌部材50の移動を規制する。
次に、前記構成の回転ツール1を備えた接合装置3の構成を説明する。かかる接合装置3は、回転ツール1の回転軸12に伝達する回転力を出力する動力手段(図示せず)と、回転ツール1の固定部11を保持して回転ツールの位置制御を行う位置制御手段(図示せず)と、を備えている。接合装置3は、例えば位置制御を行うマシニングセンタにて構成されており、位置制御装置は、CPU等にて構成され、予め入力された位置情報に基づいて、動力手段を作動させて回転ツール1を移動させる。動力手段は、回転ツール1をXYZの3軸方向に移動させる。
次に、本発明に係る接合方法を、図6を参照して説明する。かかる接合方法では、本実施形態の回転ツール1を、被接合部材2に対して予め設定された所定の高さ位置となるように移動させて、被接合部材2に攪拌ピン51とショルダ61とを所定深さで挿入して、被接合部材2に対する摩擦攪拌接合を行う。
本実施形態に係る回転ツール1、接合装置3及び接合方法によれば、回転軸12の軸方向に対して移動可能に設けられた攪拌部材50が、弾性部材70によって先端側に向けて付勢されていることによって、攪拌ピン51を被接合部材2に挿入している間に、弾性部材70の弾性に応じて、攪拌ピン51が所定の深さにまで挿入される。接合部材や接合態様といった接合条件を考慮して、弾性部材70を設定することで、攪拌ピン51を所望の深さに挿入させることができる。つまり、回転ツール1は、弾性部材70を用いた疑似的な荷重制御を行うことができる。
次に、図8及び図9を参照しながら、第一変形例に係る回転ツール1Aについて説明する。図8及び図9に示すように、第一変形例に係る回転ツール1Aは、ホルダ21の内部に、スライド手段80が設けられている。スライド手段80は、ホルダ21の内周面に設けられている。スライド手段80は、ホルダ21の内周面に形成されたベアリング溝81と、ベアリング溝81内を摺動する複数のボール82,82・・とで構成されている。ベアリング溝81は、側面視で軸方向に長い長円状に形成されている。ベアリング溝81の深さは、ボール82の直径よりも小さくなっている。ボール82は、ベアリング溝81の内部に複数個配設される。ボール82の一部がスライド軸31の外周面に摺接するとともに他の部分がベアリング溝81の内面に摺接する。なお、その他の構成については、前記実施形態と同様であるので、同じ符号を付して説明を省略する。このような構成の回転ツール1Aによれば、ホルダ21に対してスライド軸31を軸方向にスムーズに移動させることができる。
次に、図10を参照しながら、第二変形例に係る回転ツール1Bについて説明する。第一実施形態では、攪拌部材50は攪拌ピン51とショルダ61とを備えたコンベンショナル型であるが、これに限定されるものではない。第二変形例の攪拌部材50aは、図10に示すように、ショルダのないショルダレス型となっている。その他の構成は前記実施形態と同様であるので、同じ符号を付して説明を省略する。
次に、図11及び図12を参照しながら、第二実施形態に係る回転ツール1Cについて説明する。第二実施形態に係る回転ツール1Cは、ホルダ21とスライド軸31とを有する本体部10、連結部41と攪拌ピン53とを有する攪拌部材50a、弾性部材70、及び規制部材100Cを備えている。基本的な構成は、前記した実施形態及び変形例と同じであるため、同じ符号を付して説明を省略する。
次に、図13及び図14を参照しながら、第三実施形態に係る回転ツール1Dについて説明する。第三実施形態に係る回転ツール1Dは、ホルダ21とスライド軸31とを有する本体部10、連結部41と攪拌ピン53を有する攪拌部材50a、弾性部材70、及び規制部材100Dを備えている。基本的な構成は、前記した実施形態及び変形例と同じであるため、同じ符号を付して説明を省略する。
次に、図15及び図16を参照しながら、第四実施形態に係る回転ツール1Eについて説明する。第四実施形態に係る回転ツール1Eは、ホルダ21とスライド軸31とを有する本体部10、連結部41と攪拌ピン53とを有する攪拌部材50a、弾性部材70、及び規制部材100Eを備えている。基本的な構成は、前記した実施形態及び変形例と同じであるため、同じ符号を付して説明を省略する。
次に、図17及び図18を参照しながら、第五実施形態に係る回転ツール1Fについて説明する。第五実施形態に係る回転ツール1Fは、ホルダ21とスライド軸31とを有する本体部10、連結部41と攪拌ピン51B53とを有する攪拌部材50a、弾性部材70、及び規制部材100Fを備えている。基本的な構成は、前記した実施形態及び変形例と同じであるため、同じ符号を付して説明を省略する。
次に、図19及び図20を参照しながら、第六実施形態に係る回転ツール1Gについて説明する。第六実施形態に係る回転ツール1Gは、ホルダ21とスライド軸31とを有する本体部10、連結部41と攪拌ピン53とを有する攪拌部材50a、弾性部材70、及び規制部材100Gを備えている。基本的な構成は、前記した実施形態及び変形例と同じであるため、同じ符号を付して説明を省略する。
次に、図21及び図22を参照しながら、第七実施形態に係る回転ツール1Hについて説明する。第七実施形態に係る回転ツール1Hは、ホルダ21とスライド軸31とを有する本体部10、連結部41と攪拌ピン53hとを有する攪拌部材50h、及び弾性部材70を備えている。基本的な構成は、前記した実施形態及び変形例と同じであるため、同じ符号を付して説明を省略する。
以上、本発明の実施形態について説明したが、本発明の趣旨に反しない範囲において適宜設計変更が可能である。前記実施形態では、ホルダ21にキー溝23が形成され、スライド軸31にキー32が形成されているが、これに限定されるものではない。ホルダ21にキーを形成し、スライド軸31にキー溝を形成してもよい。
