Description

本考案は、特に切れ刃を回転させながら工作物に孔を開ける交換式フライスに関するものである。 In particular, the present invention relates to an exchangeable milling machine for making a hole in a workpiece while rotating a cutting edge.

図９に示すように、従来のフライスは、主軸５０と、該主軸５０の上面に設けられると共に前方へ延出する延長用部材５１と、該延長用部材５１の先端に設けられ、上方へ延出するブラケット５２とを有し、延長用部材５１の中央に長手方向に沿って穿孔５４が貫穿される。 As shown in FIG. 9, the conventional milling cutter is provided with a main shaft 50, an extension member 51 provided on the upper surface of the main shaft 50 and extending forward, and provided at the tip of the extension member 51 and extending upward. The perforation 54 is penetrated in the center of the extension member 51 along the longitudinal direction.

従来のフライスを従来の調整装置４０に取り付ける時は、螺子により切れ刃５３をブラケット５２に取り付けて固定すると共に、調整装置４０の上段部に設けられる調整部４１に主軸５０を挿入して固定し、その後、ボルト５５を穿孔５４に差し込んで、調整部４１の上面に形成される装置ネジ穴４２に螺合し、上記フライスを調整装置４０の上部に固定する。この構成によれば、該切れ刃５３を回転させることにより、工作物に孔を開けることができる。 When the conventional milling machine is attached to the conventional adjustment device 40, the cutting blade 53 is attached to the bracket 52 and fixed by a screw, and the spindle 50 is inserted and fixed to the adjustment portion 41 provided on the upper stage of the adjustment device 40. Thereafter, the bolt 55 is inserted into the perforation 54 and screwed into the device screw hole 42 formed on the upper surface of the adjusting portion 41, and the milling cutter is fixed to the upper portion of the adjusting device 40. According to this configuration, the workpiece can be perforated by rotating the cutting edge 53.

さらに、前記調整部４１により主軸５０を調整装置４０の中心から半径方向へ移動させることによって、延長用部材５１及び切れ刃５３を移動させれば、上記調整装置４０の中心に対する切れ刃５３の位置を移動させることができるので、工作物に開ける穴の半径を変更することができる。 Further, if the extension member 51 and the cutting blade 53 are moved by moving the main shaft 50 in the radial direction from the center of the adjusting device 40 by the adjusting unit 41, the position of the cutting blade 53 with respect to the center of the adjusting device 40. Can be moved so that the radius of the hole drilled in the workpiece can be changed.

しかしながら、前記従来の構成は、主軸５０と延長用部材５１とブラケット５２とが一体に形成されていることから、延長用部材５１の長さを変更することができないので、切れ刃５３の位置の変更に制限がある。故に、その穴の半径を大幅に変更する時には、先ずそれぞれサイズの異なるフライスを複数準備しておき、その中からサイズの合ったフライスに交換しなければならないことから、着脱作業が面倒であり、時間の浪費となる。 However, since the main shaft 50, the extending member 51, and the bracket 52 are integrally formed in the conventional configuration, the length of the extending member 51 cannot be changed. There are restrictions on changes. Therefore, when drastically changing the radius of the hole, it is necessary to first prepare a plurality of milling cutters of different sizes and replace them with matching milling cutters. This is a waste of time.
