Claims (2)
- 内面を樹脂層で被覆した鋼管に形成した貫通孔周囲内面の樹脂層を除去する内面研磨治具であって、
回転軸の先端に取付けられたカップブラシと、ハウジングと圧縮ばねと保持カバー及び把持部を有し、
カップブラシは、研磨砥粒を含ませたポリアミド樹脂で形成された樹脂フィラメントと、多数の樹脂フィラメントの一方の端部を外周に沿って固定し、樹脂フィラメントの先端部の外周が前記鋼管の貫通孔の内周より大きくなるように放射状に保持する保持部を有し、該保持部は、樹脂フィラメントの取付部と反対側に、外周面に一定幅の溝を有する連結部を有し、
ハウジングは、円筒状に形成され一方に開口を有し、カップブラシを保持部側から収容し、
圧縮ばねはハウジングの底面とカップブラシの間に配置され、カップブラシに対してハウジング開口側の力を作用させ、
保持カバーは圧縮ばねの力が作用しているカップブラシをハウジング内に保持し、
把持部は、弾性部材で形成され、先端にカップブラシの保持部に有する連結部と係合するフックを有するホルダを複数有し、ハウジングの底面に着脱自在に取付けられ、
前記鋼管に形成した貫通孔に挿入されて回転軸を回転しながら徐々に引き上げると、放射状に広がったフィラメントの先端部が貫通孔周囲の内面樹脂層に回転しながら押し付けられて研磨し、カップブラシがハウジング内に押し込まれると、カップブラシの保持部に有する連結部に設けられた溝に把持部のホルダのフックを係合させてカップブラシを保持して、カップブラシのフィラメントの放射状に広がった先端部を保持カバーの内周端で押えてフィラメントの先端部の外周を貫通孔の直径より小さくすることを特徴とする内面研磨治具。 - 前記カップブラシは回転軸に着脱自在に取付けられている請求項1記載の内面研磨治具。
