大型数控滚齿机刀架精度调整及检测方法探讨

Discussion on precision adjustment and test method for tool holder of large-scale CNC gear hobbing machine

针对大型数控滚齿机滚刀架精度调整困难及滚刀轴轴线与活动支撑孔重合度检测不方便的问题,分析了现有国标GB/T25380-2010中推荐的测量方法对于大型数控滚齿机不适用的原因。提出了一种新的检验方法,并阐述了详细的检测步骤。此方法不仅测量原理符合检测要求,而且量具制造简单、测量准确、易于调整装配精度;并为国标GB/T25380-2010的修订提供参考。

Aiming at the issues about difficulties of precision adjustment for tool holder and inconvenient coaxial de- gree test between hob shaft axis and active supporting hole of large - scale CNC gear hobbing machine, the reason why the recommended test method in current national standard GB / T25380 -2010 is not applicable for large -scale CNC gear hobbing machine is analyzed. A new test method is proposed and detailed test procedure is presented in the paper. The test principle of the method meets test require- ments, test tool is easy to manufacture, the method is accurate and is easier to adjust assembly preci- sion. Furthermore, the reference for revision of the standard GB/T25380 -2010 is provided.
