凸轮是机械制造中很重要的控制元件。随着生产的发展,我厂为汽车、拖拉机、轮船制造和石油工业提供的工作母机——凸轮轴车床和切管机床中出现了多种多样的凸轮,既有径向凸轮,又有轴向凸轮,也有凸轮模板和凸轮轴。有的基圆大到φ400,有的升程高达158毫米。由于过去我厂没有凸轮检查仪,曾采用光学分度头卧式测长仪读数头测量径向凸轮,用光学分度头和立式测长仪测量轴向齿轮。因为这些方法均属于临时组合,不仅不易保证精度,也不易提高检测速度,远远满足不了生产需要。为了适应上质量、上
Cam is a very important control element in machine manufacture. With the development of production, our factory has provided a variety of cams in the machine tools of camshaft lathe and pipe cutting machine for automobile, tractor, shipbuilding and oil industry. Both radial cams and axial Cam, but also cam template and camshaft. Some basic circle up to φ400, and some as high as 158 mm lift. Because in the past I did not cam tester, had used optical indexing head horizontal length gauge reading head measuring radial cam, with optical indexing head and vertical length measuring instrument axial gear. Because these methods belong to a temporary combination, not only not easy to ensure accuracy, it is not easy to improve the detection speed, far can not meet the production needs. In order to adapt to the quality, on
