摘要
高精度细长轴在精密机械设备和仪器仪表中使用很多。针对现有加工手段存在工序复杂、精度不易保证、加工效率低下等缺点,提出了基于自适应控制思想的高精度细长轴高效数控加工系统的解决方案。采用该系统可以很方便高效地加工出各种高精度细长轴。在控制好数控随动支架的位移精度和检测系统的精度的前提下,还可以实现超高精度、超长细长轴的高效自动加工。如能实现检测元件测杆的自动开合状态,则可以方便地实现高精度细长阶梯轴的自动加工。
The high precision slender shahs are used very widely in various precision machine equipments and apparatus, but its processing is very complicated, and has uncertain precision and low efficiency. Based on the adaptive control system, the system to processing the slender shafts with high precision and efficiency under the NC environment was put forward, which can process diversified slender shafts with various precisions. By controlling the accuracies of the displacement of the numerical control bracket and the measure system, the system can process the slender shafts with ultra - precision and ultra - length. If the status of automatic switching on and off of the measure sensors could be realized, the automatic processing of slender hierarchic shafts with high precision and accuracy can be realized conveniently.
