前記位相調節手段は、前記支持台に設けられ、前記固定部材に向けて進退可能で、当該固定部材の外周面に形成された凹部に嵌合可能なピストンロッドを有する
ことを特徴とする。
本発明の第一番目の実施形態に係るクランプ装置について、図1および図2を参照して説明する。
本発明の第二番目の実施形態に係るクランプ装置について、図3を参照して説明する。本実施形態では、取付台の段差部の代わりに、ガイド部材およびコレットを用いることでワークの芯出しを行っている。本実施形態では、上述した第一番目の実施形態に係るクランプ装置が具備する取付台の代わりを、取付台とコレットとガイド部材で構成した装置であって、それ以外は同じ器具を具備する。本実施形態では、第一番目の実施形態に係るクランプ装置と同じ器具には同一符号を付記しその説明を省略する。
本発明の第三番目の実施形態に係るクランプ装置について、図4および図5を参照して説明する。本実施形態は、上述した第二番目の実施形態に係るクランプ装置にて、固定部材を搬送する搬送装置をさらに設けた構成になっている。本実施形態では、第二番目の実施形態に係るクランプ装置と同じ器具には同一符号を付記しその説明を省略する。
取付台110の基準面111上にワーク101が配置され、コレット120が下方に向けて引き込まれる。すなわち、ワーク101の芯出しが行われた状態にて取付台110の基準面111上にワーク101が配置されている。続いて、コラム300を旋回しワーク101に対向する箇所に移動機構220を配置する。すなわち、ワーク101の上方に固定部材10を配置する。続いて、ピストンロッド225を伸長して、支持台210をレール221に沿って下方へ移動する。続いて、支持台110を旋回し、固定部材10と押力付与具20とを連結する。続いて、位相調節機構230のピストンロッド232を収縮しておき、移動機構220のピストンロッド225をさらに伸長して、支持台210をさらに下方に移動する。この状態にて、工具をワーク101の内周面101aで囲まれる領域内に配置し、ワーク101の内周面101aを研削加工など仕上げ加工する。
まず、工具をワーク101の内周面101aで囲まれる領域から上方へ移動し、ワーク101の上方から離れた箇所へ工具を移動しておく。続いて、移動機構220のピストンロッド225を収縮して、支持台210をレール221に沿って上方に移動する。支持台210の段差部212を固定部材10の下端部に近接配置する。続いて、必要に応じて取付台110を旋回する。続いて、位相調節機構230のピストンロッド232を伸長して、ピストンロッド232の先端部を固定部材10の凹部15に差し込む。続いて、取付台110を旋回し、固定部材10と押力付与具20の連結を解除する。続いて、移動機構220のピストンロッド225を収縮し、支持台210および固定部材10をレール221に沿って上方へ移動する。必要に応じてコラム300を旋回する。これにより、固定部材10をワーク101の上方から離れた位置に配置する。
