登车桥误差如何减小？

在加工登车桥http://www.sdsjpt.net/过程中可能会遇到很多误差，我们只有处理好这些误差才能让登车桥更好的为我们服务，下面济南荣凯升降机械的有关专家就给大家介绍一下登车桥误差减小的措施。

1、登车桥工件装夹过紧或夹紧部位不当，造成工件变形，应合理选择夹紧部位，正确夹紧工件额，夹紧部位重复精度差及夹紧不牢固，应重新调整夹紧部件，保证重复定位精度和夹紧牢固。
Ramps workpiece clamping tight or improper clamping area, causing deformation of the workpiece, clamping site should be a reasonable choice, the correct amount of clamp the workpiece clamping parts and clamping repeatability difference is not strong, you should re-adjust the clamping member, ensure repeat positioning accuracy and clamp securely.

2、登车桥主轴轴向窜动太大，应调整主轴上背母，减少轴向间隙，保证在0.07mm之间。
Ramps shaft axial movement too, the mother should be adjusted on the spindle back, reducing the axial gap between guaranteed 0.07mm.

3、登车桥主轴锥孔与钻头锥柄配合不好，应用铸铁莫氏锥棒研磨锥孔，保证与标准检验心棒的接触面积不小于70%。
Ramps spindle taper and taper shank drill with the bad, use iron rods Morse taper grinding, assurance and standard test mandrel contact area of not less than 70%.

4、登车桥http://www.sdsjpt.net/主轴锥孔内有毛刺或研伤，造成钻头倾斜，应用刮刀修刮内锥孔毛刺或研仿部位，保证锥孔轴心线的径向圆跳动误差靠主轴端小于0.02mm。
Ramps spindle taper has a burr hole or grind injury, causing the bit tilted, application scraper scratch repair glitches or research within the cone imitation parts, to ensure radial runout error by the cone axis of the spindle nose less than 0.02mm.
