摘要
以YK3150E数控滚齿机床为研究对象,通过多体系统理论研究法,得到机床的拓扑结构,利用低序体阵列对其进行数字化表述;根据所得拓扑结构分析计算相邻部件产生的误差,结合坐标变换建立误差几何模型,通过变系数微分法,对几何模型进行误差解耦,最终求得机床各轴的误差补偿量。根据所得到的误差补偿量,对齿轮加工精度进行修正,提高了齿轮精度。
Taking YK3150E NC gear hobbing machine as the object, it uses the method of multi-body system to build the topological structure of the machine tool, analyzes the topology error calculation of adjacent components, combines the coordinate transformation error to establish the geometrical model. It applies variable coefficient differential method to obtain the error decoupling of geometric model, analyzes the error compensation amount of each axis of machine tool. The results show that the method can improve the gear accuracy.
