我厂在普通外圆磨床磨削潜水泵轴外圆表面,一直采用以泵轴两端中心孔作定位基准,表面质量达不到设计要求。为此,我们设计了不调头磨削夹具。它是利用泵轴键槽作为传动键,取代鸡心夹头作为传递扭矩,使磨削砂轮能行至泵轴终端,保证了泵轴磨削一次完成,提高了磨削质量。 使用时,传动键6(见图)带有螺钉5,在转动盘3的槽内可灵活移动,调整轴向位置。开始工作
I plant grinding ordinary cylindrical grinding submersible pump shaft surface, has been used to both ends of the shaft center hole for the positioning of the benchmark, the surface quality of less than the design requirements. To this end, we have designed a non-U-turn grinding fixture. It is the use of pump shaft keyway as the drive key, instead of the chicken heart chuck as the transmission torque, the grinding wheel can go to the end of the pump shaft to ensure a complete grinding of the shaft to improve the quality of grinding. When in use, the transmission key 6 (see picture) is provided with a screw 5, which can be flexibly moved in the groove of the rotating disk 3 to adjust the axial position. start working
