凸轮是我厂生产的计程仪中的一件关键件,不仅加工工艺复杂,而且计量也很繁琐,有的一件凸轮曲线,需要通过2882个点的计量才能得出,由于没有专用设备,采取逐点人工测量,速度慢,效率差,不能满足生产要求。在批林批孔运动中,我厂成立了一个三结合的设计试制小组,试制成功凸轮自动比较测量仪,仪器采用非电量的电测量方式,以比较法和标准凸轮作比较,只需一个人,用1分半时间,就能测量任意一个凸轮,从记录图上不仅可以得出是否合格的结论,而且也能指出需要返修的部位和返修量的大小,大大地减轻计量人员的劳
Cam is a key part of our factory’s measuring range meter, not only complicated processing technology, but also measurement is very complicated, and some a cam curve, need to measure through 2882 points can be drawn, because there is no special equipment, to take the Point of manual measurement, slow, poor efficiency, can not meet the production requirements. In the bidding hole motion, I set up a plant with a combination of trial design team, the successful trial of the cam automatic comparison meter, the instrument uses non-electric power measurement methods to comparison method and standard cam for comparison, only one person , With 1 minute and a half hours, you can measure any one of the cam, not only from the record can be drawn conclusions qualified, but also pointed out that the need to repair the site and the amount of rework, greatly reducing the labor of measuring staff
