一种适用于联动加工的数控回转工作台
|
摘要
基于现有数控回转工作台结构在参与联动加工时精度及稳定性差的问题,开发设计了一种适用于联动加工的数控回转工作台。应用纯滚动摩擦的推力向心组合轴承,使转台达到更高的回转速度,避免工作台回转时的浮起动作,有效提高联动加工的精度。双电动机驱动结构让转台具有更高的定位精度和稳定性,更适合联动加工。
Based on the problem of poor precision and stability of the existing CNC rotary table structure in linkage machining,a CNC rotary table for linkage machining is developed and designed. Using pure rolling friction thrust oriented combined bearings,the rotary workbench can achieve a higher rotation speed,avoid the floating action when the workbench is turned,and effectively improve the precision of linkage machining. The dual motor drive structure allows the rotary workbench to have higher positioning accuracy and stability,and is more suitable for linkage machining.
