Abstract
【解決手段】流体の流路を形成する弁本体部110と、前記弁本体部110における弁座118に密着係合可能な弁体124を駆動する弁駆動部120とを備えた弁装置101における前記弁座118を加工する弁座加工機1であって、前記弁本体部110に取り付けられる台座部10と、当該台座部10に対して異なる二軸方向に移動可能な本体部20と、当該本体部20に対して前記弁体124の駆動方向に移動可能な支持部30と、当該支持部30に対して前記弁体124の駆動方向と平行な軸回りに回動可能な主軸40と、前記弁座118を加工するための工具Tを保持する工具ホルダ50とを備えて成る。
【選択図】図2
Description
また、工具ホルダに切削刃の形状を異にする複数の切削工具を付け替えて弁座の加工を行うことにより、弁座を弁体に対応した形状に容易に加工することができる。

また、押圧手段によって本体部と台座部との間に隙間を形成することにより、当該隙間(本体部と台座部との間)に高さ調整ライナを挿入することができる。よって、例えば、本体部の一端側に高さ調整ライナを挟み込んで本体部の一端側のみを高くすることにより、台座部に対する本体部(主軸)の傾きを調整することができる。
また、工具ホルダに切削刃の形状を異にする複数の切削工具を付け替えて弁座の加工を行うことにより、弁座を弁体に対応した形状に容易に加工することができる。
