我厂在更生修理管鉗子中,研究與使用了一種較簡單的夾具,解決了修理絲扣的困難問题,克服了没有頂針眼修扣時發生的擺動現象,保證修配質量,提高了效率。其構造和使用方法如图,把夾具體(1)夾在車床的卡盤上找正,然後把工作物(管鉗子頭)放在其中間,卽夾具體槽中。利用夾塊(3)夾住工作物(4),同時用被帽(2)擰緊,使鉗子頭牢牢的夾在夾具體內,再用頂絲(5)頂上工作物的另一端,最後用床尾的頂針頂住頂丝(5)的中心
In our factory, we have researched and used a simple fixture to solve the difficult problem of repairing the screw thread, overcoming the swinging phenomenon when there is no thimble repair, so as to ensure the quality of repair and improve the efficiency. The structure and use of the method shown in Figure, the clamp body (1) clamp on the lathe to find the chuck, and then the work (pipe clamp head) in the middle, 卽 clamp the specific slot. The work piece (4) is clamped by the clamping block (3) while being tightened by the cap (2) so that the pliers head is firmly clamped in the clamping body, the top end of the work piece is then pressed against the top wire (5) The end of the bed tail thimble top (5) of the center
