加工孔小片薄的零件外圆时,我们可以应用如图所示的夹具。该夹具是由锥形轴2,丁形定位器1及活动顶尖3组成。工件成组地装在定位器1上。并用顶针3的轴向力来顶紧於1和2的端面间,这时所产生之磨擦力,是足以防止零件在加工过程中在2、2之间的滑动。加工薄片的夹具@袁天洪 When machining small holes in a small part of a hole, we can apply the jig shown in the figure. The fixture is composed of a tapered shaft 2, a Ding shaped retainer 1 and a movable center 3. Workpieces are mounted in groups on the positioner 1. And with the axial force Thimble 3 to 1 and 2 in the top tight between the end, then the friction generated is sufficient to prevent parts in the process of sliding between 2,2.
