【発明の属する技術分野】
本発明は、鉄道車両等の外板部材の接合部を摩擦攪拌接合する方法、その装置と、摩擦攪拌接合用の構造部材に関する。
【0002】
【従来の技術】
例えば、摩擦攪拌接合方法は、部材の接合部に挿入した工具を回転させながら部材に対して相対的に移動させ、工具に近接した領域の部材を塑性流動させ、部材を固相接合する方法である。
【0003】
この場合、突き合せた部材間の隙間が重要である。隙間が過大となると、良好に接合できない。鉄道車両の車体のように、側構体と妻構体との接合部にあっては部材の製作誤差が大きくなりやすく、隙間が過大になりやすい。
【0004】
下記特許文献1では、接合すべき2つの部材の突き合せ部にスリットを設けて隙間を一定とし、次にこの隙間に補填材を配置して摩擦攪拌接合をしている。

特開2002−001444号公報(EP11478332A2)
【0006】
【発明が解決しようとする課題】
本発明は、鉄道車両の妻と側構体と接合部を自動的に摩擦攪拌接合する方法、その装置と、摩擦攪拌接合に適した構造部材を提供するものである。
【0007】
【課題を解決するための手段】
本願発明は、鉄道車両の屋根構体、台枠、側構体を鉄道車両の長手方向に沿って摩擦攪拌接合し、
次に、前記接合構造体の長手方向端部を妻構体に突き合わせ、また、前記突き合わせ部の車内側に垂直方向に沿って前記屋根構体または屋根構体と前記側構体との接続部の雨樋からの雨水を下方に導く筒状の雨樋部材を配置し、左右の前記雨樋部材の間に荷重受け部材を配置し、
車外側から、前記雨樋部材を裏当て金として、前記突き合わせ部を摩擦攪拌接合すること、
を特徴とする。
【0008】
【発明の実施の形態】
図1は、本発明を適用する鉄道車両の端部を示す斜視図である。
全体を符号1で示す車体は、台枠2上に側構体4,尾根構体6を有し、構体の端部には妻構体8が接合部10を介して接合される。妻構体8は車体1の長手方向の端部を閉鎖するもので、隣接する車両に行くための管通路9が有る。妻構体8の外周部は側構体4、屋根構体6に平行で、これらに突き合わせられて接合されている。
【0009】
図2の断面図に示すように突き合せ部(接合部)10の内側には、雨樋部材20が配置される。この雨樋部材20は、柱状で、中空の内部空間22は、尾根構体6から落下する雨滴または屋根構体6と側構体4との接続部の雨樋から落下する雨滴を下方に案内するものである。雨樋部材20の車外側の面に、側構体4、妻構体8の端部が重なっている。側構体4の端部と妻構体8の端部とは突き合せられている。雨樋部材20の突出片28は側構え体4の中空押出し形材の内面側の面5に適宜溶接されている。
【0010】
妻構体8はアルミニウム合金製であり、側構体4、屋根構体6との突き合せ部を有する。妻構体8の突き合せ部10のための突片8bは妻構体の他に部分と溶接または、プレス、または逐次成型で、一体に構成されている。逐次成型は特許文献2に示されている。屋根構体6と妻構体8との突き合せ部は従来と同様に溶接される。
本発明は、側構体4と妻構体8との突き合せ部10を摩擦攪拌接合する方法に関する。
【0011】
図3は、本発明の接合装置の概要を示す正面図、図4は側面図である。
車体1は、定盤30上に設けた構体支持装置40により拘束支持される。車両の内側には、摩擦攪拌接合による荷重を受ける荷重受け部材50が複数取付けられる。
【0012】
全体を符号100で示す接合装置は、車両の外側に立設される支柱110を有し、支柱110には水平方向に設けられる複数本の水平方向レール112が取付けられる。この水平方向レール112に対して、案内される走行ユニット120は、リニアガイド116を有し、コロ114等を介してレール112に支持される。
この走行ユニット120に対して接合ユニット130が垂直方向に移動自在に支持される。
【0013】
接合ユニット130は、スリット加工ユニット140と摩擦攪拌接合ユニット150により構成される。
スリット加工ユニット140と摩擦攪拌接合ユニット150の間には、充填材の供給ユニット160が装備される。
【0014】
図5は、接合ユニットの構成を示す説明図、図6は図5の各矢視図である。
スリット加工ユニット140は、溝加工用の切削工具142を備えて、側構体4と妻構体8との突き合せ部(接合部)10の隙間G1を均一の幅寸法に切削加工する。この溝加工による図6の(b)に示すように、均一な幅寸法の溝G2が形成される。
【0015】
次に、この溝G2に対して、充填材供給ユニット160により充填材180を挿入する。この充填材180は、突き合せ部の側構体4、妻構体6と同一材料のアルミニウム合金を帯状にした材料であって、溝G2に挿入、拘束しやすいように、断面形状はT字形をしている。
【0016】
充填材供給ユニット160は、スリット加工ユニットの切削工具142と摩擦攪拌接合ユニット150の摩擦攪拌接合工具152との間にあり、充填材18を上方から下方に供給している。図示してはいないが、充填材180をローラで溝G2に押し込んでいる。
摩擦攪拌接合ユニット150の摩擦攪拌接合工具152は、この挿入された充填材を中心として摩擦攪拌接合を行い、摩擦攪拌接合部FWを形成する。
【0017】
上述した一連の工程により、接合部を自動的に摩擦攪拌接合することができる。
つまり、突き合わせ部の下端から上端に向けて、突合せ部10を切削しつつ、その溝G2に充填材180を挿入しつつ、摩擦攪拌接合工具152を回転させながら挿入し移動させ、摩擦攪拌接合するものである。
また、接合部を均一な幅寸法に切削し、充填材180を供給して摩擦攪拌接合するので、確実で強度の高い接合部を得ることができる。
【0018】
側構体4の端部、および妻構体6の端部は雨樋部材20の断面が四角形の一辺の平坦面に重なっている。突き合せ部を摩擦攪拌接合する際に、突き合せ部に大きな荷重がかかるが、この荷重は雨樋部材20で支えられ、該雨樋部材20は荷重受け部材50を介して他方の雨樋部材20で支持され、左右から、摩擦攪拌接合が行われるので、摩擦攪拌接合は良好に接合され、接合部が曲がって凹状になることがなく、見栄えのよい接合部FWを得ることができる。
摩擦攪拌接合後、残った充填材180は切削によって平らにする。
【0019】
図7は、本発明の接合装置の他の実施例を示し、図8は図7のE−E矢視図を示す。
スリット加工ユニット140は、スリットカッター142と、スリットカッター142の位置を接合部の中心に倣うためのセンサ144を有する。同様に摩擦攪拌接合ユニット150も摩擦攪拌接合工具152を接合部の中心に倣うためのセンサ154を備える。
【0020】
充填材180の供給ユニット160は、送給ローラ170,172を有し、充填材180を挟持した状態で充填材180を送給する。
すなわち、摩擦攪拌接合工具152により、矢印S方向に接合が行われる際に、充填材180には矢印Rで示す充填材180を供給源側へ戻そうとする推力が作用する。
【0021】
そこで、送給ローラ170に駆動力を与えて充填材180を摩擦攪拌接合工具152側へ積極的に送る構成を備える。つまり、送給ローラ170と172で上下から充填材180を挟んでいる。
摩擦攪拌接合工具152の直前に装備する押えロール156は、充填材がこの推力により溝から突出しようとする作用を防止する機能を備える。
本実施例装置によれば、より確実な接合を達成することができる。
【0022】
図9は、本発明に適用される雨樋部材200に充填材の機能を付加した例を示す。雨樋部材200の車外側の面には充填材180に相当する突出部204と妻構体8の突片8bに重なる突出部206とを有する。
突出部204,206を有する雨樋部材200は押出し形材で設けることができる。
このものは、溝G2を切削することはない。
【0023】
側構体4の端部と妻構体8の突片8bの端部と突出部204の間の間の隙間は、突出部204の頂部、突出片206の金属によって埋められる。摩擦攪拌接合工具の小径部と大径部との境は突出部206内に位置している。摩擦攪拌接合後、残った突出部204,206は切削加工を施す。
【0024】
図10は、構造部材の更に他の例を示す。
雨樋部材210は、突出部214の頂部の両側に突出部216,216bを有する。摩擦攪拌接合工具の両側に突出部216,216bを有するので、良好に接合できる。
【0025】
図11は、雨樋部材の更に他の例を示す。
突出部226,226bと車外側の面の隙間は入り口側が拡大しており、側構体4、妻構体6の挿入を容易にしている。
