Description
本願は、2012年9月18日に日本に出願された特願2012-204689号について優先権を主張し、その内容をここに援用する。
上記構成によれば、溶接ビードの直上の第二シール部材にかかる面圧を下げることができる。これにより、第二シール部材の摩耗の低減を図ることができる。
上記構成によれば、グランドパッキンは摩擦係数が極めて小さい為、移動部を相対移動させる要求駆動力を下げることができ、溶接対象を真空チャンバに対して相対移動させる移動部の駆動源の小型化・コストダウンを図ることができる。また、シール性能が長期間維持することができるとともに、高温でかつうねりを有する溶接ビードへの追従が可能となる。
以下、本発明の実施形態について図面を参照して詳細に説明する。
図1に示すように、本実施形態の移動型真空溶接装置1は、平板状の溶接対象Tを移動させるラインコンベア2(移動部)と、局所真空式レーザ装置3とを有している。溶接対象Tは、ラインコンベア2のライン4上を移動するパレット5上に載置される。これにより溶接対象Tは、局所真空式レーザ装置3に対して相対移動される。以下、相対移動の方向を単に移動方向Dと呼ぶ。
また、真空チャンバ7は、ホルダー12の対向する一方の二辺の長手方向が、移動方向に沿い、他方の二辺が溶接箇所を跨ぐように配置される。
アクチュエータ10は油圧シリンダーであり、ロッド11が真空チャンバ7の上面7aを押圧することによって、シール部8に対しシールに必要な予圧を与える予圧部として機能する。即ち、シール部8にはアクチュエータ10によって予め荷重が加えられている。
なお、アクチュエータ10は、油圧シリンダーに限ることはなく、シール部8に必要な予圧を与えることができれば、空気圧シリンダーや電動シリンダー、回転ねじ機構等を採用することができる。
なお、第二シール部材28は、移動方向Dに直交する二辺両方に設ける必要はなく、少なくとも溶接によって形成された溶接ビードWが通過する移動方向の後方側のみに設ける構成としてもよい。
図4に示すように、第二シール部材28は、断面四角形状をなしており、凹条溝26は、第二シール部材28に対応した形状とされている。
まず、アクチュエータ10によってシール部8に予圧が加えられている状態でレーザ光の焦点が溶接対象Tの溶接箇所に一致するように、焦点合わせを行う。次いで、この溶接位置での溶接対象Tの溶接箇所に対して、真空チャンバ7を当接させるように予圧が加えられた後、真空ポンプ20により真空引きすることで、真空チャンバ7内の溶接位置の周囲を真空環境とする。
また、第一シール部材27として真空グリースを塗布したOリングを採用したことによって、例えばガスケットと比較して摩擦係数が小さくなるため、溶接対象Tの相対移動に要するラインコンベア2の駆動力を低減することができる。
次に本発明の第二実施形態に係る移動型真空溶接装置について説明する。図6は、本発明の第二実施形態に係るホルダー12と第二シール部材28を示す斜視図である。なお、以下に示す各実施形態では、上述した第一実施形態との相違点を中心に述べ、同様の部分についてはその説明を省略する。
具体的には、図6に示すように、板バネ29は、第二シール部材28の長手方向に沿って等間隔に複数(本実施形態では3つ)設置されている。板バネ29は、単一の矩形形状の金属板によって形成されており、第二シール部材28をホルダー12に対して下方、即ち、溶接対象Tに向かう方向に付勢するように設置されている。
なお、弾性部材としては、板バネ29に限ることはなく、皿バネや、圧縮コイルバネを採用することも可能である。
また、複数の板バネ29のうち、溶接ビードWの直上に位置する板バネ29の弾性率を小さくする構成とした場合、溶接ビードWの直上の第二シール部材28にかかる面圧を下げることができる。これにより、第二シール部材28の摩耗の低減を図ることができる。
次に本発明の第三実施形態に係る移動型真空溶接装置について説明する。本実施形態の特徴は、ホルダー12の凹条溝26の第二シール部材28に対向する面26aに凹部30が形成されていることである。
具体的には、図7に示すように、凹部30は溶接ビードWの直上に形成されている。凹部30は、溶接ビードWの形状に則した断面形状を有するように形成されている。例えば、溶接ビードWの形状が、上方に凸の滑らかな山型形状とされている場合、凹部30は、凹条溝26の第二シール部材28に対向する面26aより、上方に滑らかに凹んだ形状となっている。
次に本発明の第四実施形態に係る移動型真空溶接装置1Dについて説明する。
図10に示すように、本実施形態の局所真空式レーザ装置3の真空チャンバ7と溶接ヘッド9とは、溶接ヘッド9を溶接対象Tの表面に直交する方向Vに移動自在に支持するとともに、溶接ヘッド9と真空チャンバ7との間を封止する可動封止部32を介して接続されている。可動封止部32は、金属製のベローズ33(ブーツ)と、ベローズ33と溶接ヘッド9のベース部15、及びベローズ33と真空チャンバ7の上面7aとの間に介在している第三密封部材34とを有している。
アクチュエータ10は、真空チャンバ7に取り付けられた延長部35を押圧するように配置されている。即ち、真空チャンバ7のみが溶接対象Tの表面に押し付けられるように構成されている。
次に本発明の第五実施形態に係る移動型真空溶接装置1Eについて説明する。
図12に示すように、本実施形態の移動型真空溶接装置1Eは、第一実施形態~第四実施形態の移動型真空溶接装置が平板状の溶接対象Tを溶接する構成であることに対して、円筒形状の第二溶接対象T2を溶接することを特徴としている。
第二溶接対象T2は、所定の支持手段により、軸回りに回転自在に支持されている。即ち、第二溶接対象T2は、図12の矢印方向(回転方向R)に回転自在とされている。
また、アクチュエータ10は、基礎部45に取り付けられており、シール部8Eを予圧するように構成されている。
