【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]:Aiming at the problem of NC machining of ZC3 worm gear, a method of milling worm gear by conventional milling cutter is put forward. Firstly, the mathematical model of worm gear pair is derived by gear meshing principle. Secondly, the discrete data point cloud of worm gear tooth surface is solved by MATLAB software, many groups of sectional data are intercepted from axial direction of worm gear, and the data points are fitted by least square fitting method, and the relation of tooth surface curvature change of worm gear is solved. The non-uniform cutter path partition method is used to divide the cutter path of the tooth surface, and the corresponding NC machining path path is generated. Finally, the generated machining program is simulated with VERICUT software, and its correctness is verified by comparing and analyzing the original calculated tooth surface data and the simulated tooth surface. The experiments show that this method has strong adaptability compared with the traditional worm-gear machining method, and the side milling is used to improve the milling efficiency.
