在出油阀锥面磨削过程中,由于工件的尺寸、形位精度以及光洁度都要求很高(图1),特别是2.1±0.1的长度难以保证。我厂过去在磨削出油阀锥面时,使用两个死顶尖顶住两端中心孔来进行加工。工件的中心孔大小及长度尺寸不易保证,工人在磨锥面时,多凭经验和眼力估计2.1±0.1的长度。致使不能保证质量。为此,我们设计磨出油阀锥面夹具,经过半年多的生产使用,获得了良好效 In the oil valve cone grinding process, due to the size of the workpiece, the shape accuracy and finish are demanding (Figure 1), especially the length of 2.1 ± 0.1 is difficult to guarantee. I used to grind out the oil valve cone, the use of two dead top to withstand both ends of the center hole for processing. Workpiece center hole size and length of the size of the guarantee is not easy, workers in grinding cone, with more experience and eyesight estimated 2.1 ± 0.1 length. Can not guarantee the quality. To this end, we design grinding valve cone cone fixture, after more than six months of production and use, get a good effect
