螺距送刀精度是精密丝杠车床最重要的质量指标。如何保证这项精度,也是精密丝杠车床制造的关键和最复杂的问题。现将我厂所摸索到的一些经验介绍如下。一、校正装置和它的作用图1是精密丝杠车床的传动系统和螺距送刀误差的校正装置简图。工件主轴2的旋转运动由皮带盘1传来,通过交换齿轮3带动丝杠4旋转,再通过螺母5使刀架溜板6沿床身纵向导轨移动。此时,螺母上的杠杆7压在校正板8上,由于校正板的工作面已事先
Pitch cutter precision is the most important quality precision screw lathe. How to ensure this accuracy, but also the manufacture of precision screw lathe key and most complex issue. Now I plant some of the experience found by the following. First, the calibration device and its role Figure 1 is a precision screw lathe drive system and pitch feed error correction device diagram. The rotation of the workpiece spindle 2 is transmitted from the belt reel 1, the screw 4 is driven to rotate through the exchange gear 3, and then the knife carriage 6 is moved along the longitudinal rail of the bed by the nut 5. At this moment, the lever 7 on the nut presses on the calibration plate 8, since the working surface of the calibration plate has been
