在普通车床上加工细长轴时,用普通跟刀架仍不能保证加工质量,为此,我们设计制作了类似跟刀架的专用夹具,有效地解决了细长轴扭曲变形、尺寸精度及形位误差超差等问题。使加工产品成品率达到98％,生产效率也成倍提高。夹具主体结构见图1,轴壳焊合体6的中心高为h,在车床大溜板上设弓形连接底板(安装在溜板上现成螺孔),使轴壳焊合体6与之固定。夹具固定在刀架左侧,安
In the ordinary lathe machining slender shaft, with the general with the knife still can not guarantee the quality of the processing, for which we have designed a special fixture with a similar fixture, effectively solve the slender shaft distortion, dimensional accuracy and shape Bit error tolerance and other issues. The processed product yield reached 98%, production efficiency has doubled. Fixture body structure shown in Figure 1, the axis of the shell welding body 6 is h high center, in the lathe slide plate is provided with an arcuate connecting plate (installed on the slide board screw holes made), so that the shaft shell welding body 6 with it fixed. Fixture on the left side of the knife holder, safety
