对于椭圆形零件的加工,传统加工方式存在诸多缺陷。通过对偏心轮机构的改进,设计了一种适用于椭圆零件加工的普通车床传动机构,利用此机构与车床主轴同步转动,带动刀具的自由进给,实现加工高质量椭圆手孔盖的目的。这种加工方式经生产实际应用,加工的产品质量稳定,提高了生产效率,从而验证了设计结构的合理性。 For the processing of oval parts, there are many shortcomings of the traditional processing methods. Through the improvement of the eccentric mechanism, an ordinary lathe transmission mechanism suitable for the machining of elliptical parts is designed. By using this mechanism to rotate synchronously with the lathe spindle, the tool can be freely fed to realize the purpose of processing high quality oval hand hole cover. This method of processing through the practical application of production, processing of stable product quality, improve production efficiency, thus verifying the rationality of the design structure.
