在用凸轮磨床加工一种新设计的凸轮时,首先需要制作靠模。本文提出了与习惯反靠法不同的新方法,可以根据凸轮的型线计算出与靠模相对应的从动件升程曲线,并用平面磨床来直接加工靠模。从而可以缩短靠模的制造时间和减少加工误差。用本文提出的方法,还可计算和分析凸轮磨床砂轮尺寸的误差对凸轮型线的影响。文中不仅提供了计算的原理和公式,而且也给出了一个计算实例。
When machining a newly designed cam with a cam grinder, you first need to make a master. In this paper, we propose a new method that is different from customary anti-relying method. The curve of the follower’s lift corresponding to the master can be calculated according to the profile of the cam, and the surface grinding machine can be used to directly process the master. Thus, the manufacturing time of the master can be shortened and the machining error can be reduced. Using the method proposed in this paper, the influence of the error of the size of the grinding wheel on the cam profile can also be calculated and analyzed. The paper not only provides the calculation principle and formula, but also gives a calculation example.
