齿轮毛坯拉孔后需要修整两端面以保证端面跳动的要求。这道工序普遍的作法是将工件压入锥度芯轴内,然后用双刀精车成。但当孔径较小时,就不甚方便。为解决这一问题,我厂设计了一种精车齿坯端面(也可车外圆)的夹具,效果较好,现介绍如下: 如上图所示,将工件装于芯轴上,用搬手转动件11紧固螺钉压紧涨套10以涨紧工件,便可开车进行加工。加工完毕后,松开件11、由于芯轴与涨套间的锥度小,该夹具
Gear blank hole after the need to trimming the two ends to ensure the requirements of the end of beating. The common practice of this process is to press the workpiece into the tapered mandrel, and then use double-pole fine car into. However, when the aperture is small, it is inconvenient. In order to solve this problem, our factory has designed a kind of fixture of the end face of the fine blanks (also can be car outside the circle), the effect is better, are introduced as follows: As shown above, the workpiece is mounted on the mandrel, The hand rotating member 11 tighten the screw and press the rising sleeve 10 to tighten the work piece, then the car can be processed. After processing, the release of pieces 11, due to the taper between the mandrel and the sleeve is small, the fixture
