我厂加工电机转子外圆,是在车床上用前后顶尖定位。用鸡心夹头夹紧轴伸外圆,由车头拨杆带动转子旋转进行外圆加工的。但这种用鸡心夹头夹紧的方式有些问题,主要是由于轴伸外圆是经过磨削加工的,上面还铣有键槽。夹紧时容易被压伤或打滑划痕,严重时会造成报废。针对上述情况,我们设计了一套车夹 I plant machining rotor cylindrical, is in the lathe before and after the top positioning. Clamped with the heart-shaped chick cylinder shaft extension, driven by the front wheel lever rotation of the outer cylinder processing. However, this way with the chicken heart chuck clamping some problems, mainly due to shaft extension cylindrical grinding process, the above is also milling keyway. When it is easy to be crushed or slipping scratches, serious will result in scrapped. In view of the above situation, we designed a set of car clip
