在没有专用花键铣床的情况下,根据矩形花键的使用场合及外径定心特点,对花键轴进行简化的结构替代,并经有限元分析满足性能要求。为了保证试制花键轴的加工能在数控加工中心上完成,通过分析试制花键轴的加工要求和结构特点,采用“一顶一夹”的装夹方式,利用加工中心分度头的数控分度功能,按一定的工艺要求进行分度对键槽进行铣削。采用手工编程加工,并采用宏编程来简化。加工出来的试件基本满足使用要求。
In the absence of a dedicated spline milling machine, the spline shaft is replaced with a simplified structure based on the use of the rectangular spline and the centering of the outer diameter, and the performance requirements are satisfied by the finite element analysis. In order to ensure that the machining of the spline shaft can be finished on the CNC machining center, by analyzing the machining requirements and structural features of the spline shaft, the clamping method of “one top and one clamp” CNC indexing function, according to the requirements of a certain process for indexing keyway milling. Using manual programming and macro programming to simplify. The processed specimens basically meet the requirements of use.
