很多自动机床都广泛采用摆杆凸轮机构。据了解,许多工厂制造的凸轮,都要经过反复试用修理再加工才能正常工作。我厂情况也是如此。多年来,我们误认为是制造问题,基于“工作曲线是阿基米德螺线”这一传统概念,我们采用了“阿基米德螺线铣削装置”、“坐标镗床镗削曲线起讫位置”、“千分表加分度头检验曲线各点尺寸”等各种措施提高加工精度,但其效果犹如隔靴搔痒,并未解决问题。我们从 Many automatic machine tools are widely used swing cam mechanism. It is understood that many factories make the cam, have to go through trial and error to re-processing in order to work properly. I plant the situation is also true. Over the years, we mistakenly believe that it is a manufacturing problem. Based on the traditional concept of “work curve is Archimedes spiral”, we use “Archimedes spiral milling device”, “coordinate boring machine boring curve starting and ending position” , “Dial gauge plus indexing head test curve size” and other measures to improve the processing accuracy, but its effect is like every other tickle itch, did not solve the problem. We from
