Description
【発明の詳細な説明】 〈産業上の利用分野〉 本発明は、タレット式の数値制御工作機誠に関する。[Detailed description of the invention] <Industrial application field> The present invention relates to a turret type numerically controlled machine tool Makoto.
〈従来技術〉
工作物の穴あげ加工において、スピンドル軸線（Ｚ軸）
に対し傾斜角度の軸線穴を加工する場合、単軸主軸ｙ、
ｚ軸に対して傾斜させ、Ｚ軸と他の１軸とＺ数値制御に
より合成２軸方向に送りＺ与えて斜め穴をあけることは
公知である。<Prior art> In drilling a workpiece, the spindle axis (Z-axis)
When machining an axis line hole with an inclination angle to
It is known to drill an oblique hole by tilting the hole with respect to the Z-axis and applying feed Z in the directions of the Z-axis, another axis, and two combined axes by numerical control of the Z-axis.
このものは、角度が自由に変えられる主軸の回転伝達系
は主軸ヘッドの旋回中心と同心的に回転軸を設ける必要
があり、単軸主＠ＩＩにしかこの加工方式は適用されて
いない。従って、加工穴の寸法、形状が異なると工具交
換を行わない限り垂直穴及び傾斜穴の何れも加工するこ
とができず、そのｋめに工具交換装置を特別に設けろと
高価になる。In this case, the rotation transmission system of the spindle whose angle can be freely changed requires the rotation axis to be provided concentrically with the rotation center of the spindle head, and this processing method is only applied to the single-spindle spindle @II. Therefore, if the dimensions and shapes of the holes to be machined are different, it is impossible to machine either a vertical hole or an inclined hole unless the tool is changed, and it becomes expensive to provide a special tool changing device for that purpose.
また、複数の主軸Ｚ有するタレットヘッドの主軸駆動系
は、加工位置に対応する主軸のみ回転力が伝達されるよ
５になっている。従って、タレットヘッドの割出し位置
は等角度間隔に設定されており、この割出し位置からず
れた角度位置では主軸に回転伝達ができない。このため
前記の単軸主軸のように主軸ヘッドの割出し角度ンずら
てことによっては斜め穴の加工を行うことはできない。Further, the main shaft drive system of the turret head having a plurality of main shafts Z is configured such that rotational force is transmitted only to the main shaft corresponding to the processing position. Therefore, the index positions of the turret head are set at equal angular intervals, and rotation cannot be transmitted to the main shaft at angular positions that deviate from the index positions. For this reason, it is not possible to machine diagonal holes by shifting the index angle of the spindle head, as in the case of the single spindle described above.

This solves the problems of the prior art.
