过去我厂加工軸瓦上的固定銷部分时,是在軸瓦上划出十字线,然后夹到車床卡盘上,再用划針盘找出十字线中心,調整好后才能加工,所以輔助时間很长,質量还不能保証。工人李树南和技术人員針对这一缺点,改进了一种夹具,经实际使用,証明效果良好。 In the past, when I processed the fixed pin portion of the bearing bush, I crossed the cross line on the bearing bush and then caught the lathe chuck. Then I used the needle dial to find out the center of the cross-hair line. After adjusting, I could process it. Therefore, the auxiliary time Very long, the quality can not be guaranteed. In response to this shortcoming, worker Li Shu-nan and his technical staff improved a jig, which proved to work well after actual use.
