Claims (8)
- 1.スピンドルブレーキ(21)と作業スピンドル(7・67)とを有するモー タ駆動の手持ち工作機械であって,作業スピンドル(7・67)を遊びをもって 取り囲む中央孔(39・84)を有する円板形の工具(33・83)が,内側フ ランジ(29・79)と外側フランジ(31・81)との間に挟まれて,作業ス ピンドル(7・67)に固定されており外側フランジ(31・81)は固定ねじ 山(3785)に,作業スピンドル(7・67)の作業回転方向とは逆向きにね じはめられている形式のものにおいて,作業スピンドル(7・67)が制動せし められると,内側フランジ(29・79)と外側フランジ(31・81)との間 の工具(33・83)に対する締め付け圧力が自動的に増大せしめられるように したことを特徴とする,モータ駆動の手持ち工作機械。
- 2.引き続き回転する工具(33・83)の慣性力がフランジ(29・31・7 9・81)と工具(3383)との間の締め付け圧力を増大させるようにした, 請求項1記載の手持ち工作機械。
- 3.作業スピンドル(7・67)に対して相対的に作業回転方向に回転すること によって,内側フランジ(29・79)又は外側フランジ(31・81)が作業 スピンドル(7・67)に沿って軸方向に工具(33・83)に向かって移動す るようにした,請求項1又は2記載の手持ち工作機械。
- 4.内側フランジ(29・79)の軸方向移動を生ぜしめるために,内側フラン ジがくさび手段(43・45・87)と連結されており,このくさび手段は内側 フランジが工具(33・83)と一緒に作業回転方向に引き続き回転する際に, 内側フランジに対する軸方向の圧着又は係合によって,内側フランジに対して相 対的に滑動して,内側フランジの工具(33・83)若しくは外側フランジ(3 1・81)に対する軸方向間隔を減少させるように作用する請求項3記載の手持 ち工作機械。
- 5.内側フランジ(29・79)が,外側フランジの傾斜角αを有する固定ねじ 山(37・85)よりも急傾斜の傾斜角βを有するねじ山(87)若しくはくさ び面(43・45)に沿って,外側フランジ(31・81)と同じねじり方向で 一定限度回動可能である,請求項4あるいは請求項1から3までのいずれか1項 に記載の手持ち工作機械。
- 6.円周方向のストッパ(51・53・89・91)が,作業スピンドル(7・ 67)に対して相対的な内側フランジ(29・79)の回動を制限するようにし た,請求項5記載の手持ち工作機械。
- 7.締め付け圧力を増大させる手段(43・45)が外側フランジ(31)に配 置されている,請求項1から3までのいずれか1項に記載の手持ち工作機械。
- 8.内側フランジ(29・79)が作業スピンドル(7・67)に対して相対的 に回転不能に配置されており,外側フランジ(31・91)が,工具(3383 )に向けられた軸方向に移動可能なカム部材を有しており,該カム部材の工具( 33・83)に向かっての軸方向移動は,締め付け位置に達したときに最小であ り,作業スピンドル(7・57)に対して相対的な,慣性に基づく工具(33・ 83)の回転の際に回転連行によって最大になるようにした請求項7記載の手持 ち工作機械。
