我厂加工偏心工件,有独立公差要求,加工和检测都较麻烦。所以,我们设计了的夹具,回转体3与偏心轴1的回转中心有偏心距。当偏心轴(即机床主轴)与回转体回转中心重合时,即位置,可加工端面、车两同轴台阶圆ф32f12、ф30。当回转体转180°时,夹持套4偏心孔的中心刚好与机床主轴中心重合,即可加工台阶孔ф14.5F9和ф13F9。为保证夹具
I plant processing eccentric workpiece, an independent tolerance requirements, processing and testing are more troublesome. Therefore, we designed the fixture, the revolving body 3 and eccentric shaft rotation center 1 eccentricity. When the eccentric shaft (ie, the spindle of the machine) coincides with the center of rotation of the rotary body, that is, the position, the machined end surface, and the two coaxial steps of the car are round ф32f12 and ф30. When the slewing body turns 180 °, the center of the eccentric hole of the clamping sleeve 4 just coincides with the center of the machine spindle, and the step holes ф14.5F9 and ф13F9 can be processed. To ensure that the fixture
