滑块是乳化泵的重要零件,质量好坏,直接影响乳化泵的使用寿命。按图纸要求,滑块销孔d_0中心线与滑块外径D中心线垂直度允差0.02,D外圆表面光洁度▽7。滑块材料是ZL108。工艺要求是,精车滑块D外圆留磨削量0.2～0.3mm,然后装夹在莫氏4~#磨削滑块外网的夹具上,磨削至尺寸要求和光洁度▽8。以往一般采取通过主轴孔螺杆吊紧的办法加工,现结合零件的批量和质量要求,研
Slider is an important part of the emulsion pump, the quality of good or bad, directly affect the life of the emulsion pump. According to the drawing requirements, the tolerance of the perpendicularity between the centerline of the slider pin hole d_0 and the centerline of the outer diameter D of the slider is 0.02, and the outer surface finish of D is ▽ 7. Slider material is ZL108. The process requirement is that the outer diameter of finishing block D is 0.2 ~ 0.3mm, and then it is clamped on the fixture of the outer net of Mohs 4 ~ # grinding block and ground to size requirement and finish ▽ 8. In the past to adopt the method of screwing through the spindle hole screw processing is combined with parts of the batch and quality requirements, research
