在对星轮输出轨迹变化分析的基础上,结合数学推导,设计出一种基于行星轮运动复合原理的方孔钻削加工方法,该方法通过计算可得到孔大小与偏心大小和刀具尺寸基本关系,且能确定钻削方孔具体的位置。通过样机的研制和计算机仿真验证的结果表明,样机对正方孔的加工,特别是正方形盲孔加工有很好的效果,解决了正方形盲孔加工难的问题。 Based on the analysis of the variation of the output trajectory of the starwheel and combining with the mathematical derivation, a method of square hole drilling based on the compound principle of planetary wheel motion is designed. Through this method, the basic relationship between hole size, eccentricity and tool size , And can determine the specific location of drilling square hole. Through the development of the prototype and computer simulation results show that the prototype of the square hole processing, especially the square blind hole processing has a good effect, to solve the problem of square blind hole machining difficult.
