摘要: 为了解决大/重型或某些细长轴类零件上的等径或变径回转特征轮廓的加工问题,设计了基于2K-H(C)型行星差动原理的U轴机构,并以平旋盘为例分析了该机构的工作原理,计算了U轴进给参数。另外,还提出了多种变型方案以适应不同场景的工作需求。Abstract: A U-axis mechanism based on 2K-H (C) type planetary differential was designed to process turning contours in large/heavy workpieces or slender shafts with equal-diameter or variable-diameter sections. The working principle of the mechanism was analyzed by taking facing head as an example, providing a theoretical foundation for the U-axis feeding parameter design. Deformation systems were also proposed to meet the working requirements of different situations.
