摘要

针对ZC3型蜗轮的数控加工问题,提出一种采用常规铣刀侧铣加工蜗轮的方法。首先,通过齿轮啮合原理推导出蜗轮副的数学模型。其次,通过MATLAB软件求解出蜗轮齿面离散数据点云,从蜗轮轴向截取多组截面数据,采用最小二乘拟合法拟合截取的数据点,求解出蜗轮齿面曲率变化的关系,并以此为依据,用非均匀刀路划分法对齿面进行刀路划分,生成相应的数控加工刀路轨迹。最后,用VERICUT软件对生成的加工程序进行仿真,并用原始计算的齿面数据与仿真加工的齿面进行对比分析,验证其正确性。试验表明,该方法与传统的蜗轮加工方法相比,具有很强的适应性;同时采用侧面铣削,提高了铣削加工效率。

Abstract

In order to improve the precision of CNC machining ZC3 worm gear,a side milling method for machining worm gear is proposed. Firstly,the mathematical model for milling ZC3 worm gear is established based on the principle of gear meshing. Secondly,the worm gear tooth surface points are solved by MATLAB.By using the least square fitting method,the relationship between worm gear surface curvature and cross-sectional data from the worm gear axially is obtained. Then,the NC tool paths are generated by solving the non-uniform division method for tooth surface. Finally,the simulation of the generated machining program is carried out by using the VERICUT,the correctness of the proposed method is verified by comparing with the original calculation tooth surface data. The experiment shows that the proposed method can improve the milling universality as well as the efficiency compared with the conventional method for worm gear CNC machining.
