我厂从事车削加工的主要车床C620,由于转数低,已远远适应不了生产的要求。我们利用设备大修的时机,对床头箱进行了升速改装,由600r/min转数升速为1200r/min,效果看来是比较好的。一、改进 C620床头箱的改装见图。在结构上主要吸取了CA6140和C620-1的特点,在不改变工艺装备的前提下,在Ⅳ轴上增加斜齿轮15。它与在主轴1上增加的斜齿轮11相啮合,实行增速(两轮齿数相同).在主轴上增加结合齿轮6,分别与斜齿轮4、11接合,它们的轴向定位由调整垫3、5、12、13来调整,每个调整垫
I plant engaged in turning the main lathe C620, due to low speed, far from the production to meet the requirements. We take advantage of the timing of equipment overhaul, the headstock box was upgraded by 600r / min speed up to 1200r / min, the effect seems to be better. First, improve the C620 headstock refit shown in the figure. In the structure of the main draw CA6140 and C620-1 features, without changing the premise of the process equipment, increase in the Ⅳ axis helical gear 15. It is with the addition of the helical gear 11 in the spindle 1, the implementation of growth (the same number of teeth on both wheels.) In the main shaft to increase the coupling gear 6, respectively, and helical gears 4, 11, their axial positioning by the adjustment pad 3 , 5,12,13 to adjust each adjustment pad
