计算的原始数据:(1)被加工孔的直径与深度;(2)孔的相互位置;(3)被加工另件的材料及其机械性能;(4)要求的加工生产率。如果动力头是为已有机床设计,除上述原始数据外,尚应考虑到下面几点:(1)机床主傅动电机功率;(2)主轴允许最大轴向力;(3)机床主轴转速及进刀量;(4)主轴头的尺寸及形状;(5)主朝自床身伸出的距离;(6)主轴最大行程;(7)机床工作台垂直方向移动范围。通常钻削动力头按下列顺序设计:(1)选择加工用量,决定动力头主轴转速;
Calculated raw data: (1) diameter and depth of hole being machined; (2) mutual location of holes; (3) material of the piece to be machined and its mechanical properties; and (4) required processing productivity. If the power head is designed for existing machine tools, in addition to the above raw data, the following points should be taken into account: (1) power of the main motor of the machine tool; (2) maximum axial force of the spindle; (3) And the amount of feed; (4) the size and shape of the spindle head; (5) the distance the host heads extended from the bed; (6) the maximum travel of the spindle; (7) the vertical movement range of the machine table. Drilling head is usually designed in the following order: (1) select the amount of processing, power head spindle speed decision;
