摘　　要：根据自定心中心架的工作原理,建立了中心架平移凸轮机构的参数化模型,给出了凸轮实际廓线方程设计计算公式。针对一组设计参数,通过把凸轮廓线导入UG软件数控加工模块中,生成实体模型及数控加工代码,可采用非等径侧铣的方式对凸轮机构进行加工,为中心架平移凸轮机构的设计制造提供一种方案。Based on the working principles of the self-centering center rest,the parameter model for translation cam of the center rest was established,and the design equations for the real contour cam curve of the center rest were presented in this paper.According to a set of parameters,the soild model and NC code were generated by introducing the cam contour into the NC processing module of UG software,thus the cam could be machined by the unequal diameter side milling cutter.It provides a scheme for design and manufacture of the translation cam mechanism of the center rest.
