我们用配换挂轮的办法,解决了CO620车床铭牌上没有的19牙/英寸螺纹的车削。进给系统的换置计算如下: 计算位移:工件1转,车刀移动一个螺距1/n(n-每英寸牙数) 运动平衡方程;1·i_主·i_换·i_进=1/n·25.4/t_丝(i_换-交换齿轮副齿数比; i_主—主轴至挂轮传动比;i_进—进给箱传动比;n—每英寸牙数;
We use the method of changing the hanging wheel to solve the COZ20 lathe nameplate does not have 19 teeth / inch thread turning. The displacement of the infeed system is calculated as follows: Calculate the displacement: the workpiece 1 rotation, the tool moves a pitch 1 / n (n-teeth per inch) balance equation; 1 · i_ main i_ change i_ into = 1 / n · 25.4 / t_ wire (i_change - gear ratio of the exchange gear; i_shaft - the ratio of the main shaft to the rack and pinion; i_advance - feed box gear ratio; n - number of teeth per inch;
