摘要
目的解决主轴在高速旋转过程中的不平衡力造成回转精度降低问题.方法笔者通过建立单平面动平衡调整算法模型,提出一种新型单平面主轴在线动平衡调整方法.基于Labview平台,开发在线动平衡调整仿真软件.结合试验实测数据与传统单平面调整方法进行对比分析,验证其合理性.结果该方法能够实现主轴在线动平衡状态、质量块精确定位,与传统方法相比,振幅降低程度达10%以上.结论新型单平面动平衡调整方法能够精确定位主轴质量块校正位置,大幅度提高主轴回转精度,为高速主轴的平稳运行和工艺优化提供基础科学依据.
In order to solve the problem that the unbalanced force of spindle causes the reduction of rotation accuracy in high-speed rotating process.Methods proposed a new method of on-line dynamic balance adjustment of single-plane spindle by establishing the algorithm model of single-plane dynamic balance adjustment,Based on Labview platform,the simulation software of on-line dynamic balance adjustment was developed.Combining the experimental data with the traditional single-plane adjustment method.The reasonableness of the method is verified.Results The method can realize on-line dynamic balance of spindle and precise positioning of mass block.Compared with the traditional method,the amplitude of the spindle can be reduced by more than 10%.Conclusion The new single-plane dynamic balance adjustment method can accurately locate the corrected position of the spindle mass block,greatly improve the spindle rotation accuracy,and provide for the smooth operation and process optimization of the high-speed spindle.Basic scientific basis.
