我厂生产的泰山12拖拉机中,衬套(图1)孔是在C616车床上车削的外圆与内孔同轴度容易超差,而且停车频繁,造成车床电机发热甚至烧毁。为此,我们设计了C616车床使用的不停车离合卡簧夹具,同轴度可达0.05mm,班产量可达1000件以上。夹具底座11(图2)固定在主轴箱密封盖上,使外套1不转,定心锥套9固定在车床主轴锥孔内,同主轴一起旋转。在未装工件时,山于弹簧10的压力,使夹紧套5与定 Taishan 12 tractor I plant production, the bushing (Figure 1) hole in the C616 lathe turning cylindrical and bore coaxial easy tolerance, and frequent parking, resulting in lathe motor fever or even burn. To this end, we have designed the C616 lathe clutch clutch does not stop the fixture, coaxial up to 0.05mm, the class output up to more than 1,000. Fixture base 11 (Figure 2) is fixed to the headstock sealing cover, the jacket 1 does not turn, the centering cone 9 is fixed in the lathe spindle taper hole, together with the spindle rotation. In the unloaded workpieces, the pressure in the spring 10, the clamping sleeve 5 and set
