我们在长期模索中,发觉原导柱、导套压入端的结构(图1)与孔是线接触,稳定性很差,在进入孔时很容易发生倾斜,如不及时纠正,就会破坏孔壁、使导柱、导套装配歪斜。为此,我们对标准的导柱、导套压入端形状进行了改进(图2)。我们根据用圆锥体定位元件时,工件安装基准的中心线总是落在定位元件的中心线上这一原理,并且为了克服角度的偏倾,在导柱、导套的压入端磨制只带有斜度为15’的引入角。
In the long run, we found that the structure of the guide post and guide sleeve press-in end (Figure 1) is in line contact with the hole and has poor stability. When entering the hole, it is easy to tilt. If it is not corrected in time, the hole will be damaged Wall, so that the guide column, guide sleeve with askew. To this end, we have made improvements to the standard guide posts and guide-in ends (Figure 2). According to the principle of positioning the component with the cone, the centerline of the workpiece mounting reference always falls on the centerline of the positioning component, and in order to overcome the angular tilt, With a 15 ° lead angle.
