在加工登車橋http://www.fnae.cn/過程中可能會遇到很多誤差，我們只有處理好這些誤差才能讓登車橋更好的為我們服務(wù)，下面濟(jì)南榮凱升降機(jī)械的有關(guān)專家就給大家介紹一下登車橋誤差減小的措施。

1、登車橋工件裝夾過緊或夾緊部位不當(dāng)，造成工件變形，應(yīng)合理選擇夾緊部位，正確夾緊工件額，夾緊部位重復(fù)精度差及夾緊不牢固，應(yīng)重新調(diào)整夾緊部件，保證重復(fù)定位精度和夾緊牢固。
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、登車橋主軸軸向竄動太大，應(yīng)調(diào)整主軸上背母，減少軸向間隙，保證在0.07mm之間。
Ramps shaft axial movement too, the mother should be adjusted on the spindle back, reducing the axial gap between guaranteed 0.07mm.

3、登車橋主軸錐孔與鉆頭錐柄配合不好，應(yīng)用鑄鐵莫氏錐棒研磨錐孔，保證與標(biāo)準(zhǔn)檢驗心棒的接觸面積不小于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、登車橋http://www.fnae.cn/主軸錐孔內(nèi)有毛刺或研傷，造成鉆頭傾斜，應(yīng)用刮刀修刮內(nèi)錐孔毛刺或研仿部位，保證錐孔軸心線的徑向圓跳動誤差靠主軸端小于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.
