5 回転カム
20 固定カム
Claims (4)
- 回転力が伝達されるとともに軸方向移動が自在とされているスピンドルと、スピンドルに固定された回転カムと、回転カムと対向する固定カムと、スピンドル回転時に固定カムと回転カムとの対向面に形成されたカム面同士の滑り噛み合いで回転カム及びスピンドルの軸方向移動による振動を発生する振動ドリルにおいて、固定カムと回転カムとの軸方向滑り噛み合い量より小さい微小寸法だけ固定カムを軸方向移動自在とするとともに固定カムの上記カム面と反対側の背面を上記回転カム側に向けて付勢する緩衝材による付勢で固定カム支持部材である軸受の先端面から浮かせ、且つ上記緩衝材を、上記滑り噛み合いによる振動発生時にも固定カムの軸方向の動きを生じさせないばね荷重を有するものとしていることを特徴とする振動ドリル。
- 固定カムのカム面側に第2緩衝材を弾接させていることを特徴とする請求項1記載の振動ドリル。
- 緩衝材のばね荷重を第2緩衝材のばねよりも大としていることを特徴とする請求項2記載の振動ドリル。
- 第2緩衝材は筒状であるとともに固定カムは第2緩衝材の内周側を受けるばね受け部を備えていることを特徴とする請求項2または3記載の振動ドリル。
