看了贵刊87年6期的“车床限位顶杆”后,觉得尚有改进余地。如将锥杆一分为二,同时准备数根不同长度的螺杆及数只不同外径不同厚度的靠山头,待调整到所需位置后,用3只扁螺母并紧,可防止松动。这样,靠更换不同的螺杆和靠山头,可加工任何有端跳要求的圆柱零件。同时,在靠山头上车出2台阶孔,大台阶孔为减少接触角,提高端跳精度;小台阶孔为镗孔时镗刀伸入用。另外,靠山头的外径只是略小于工件外径,过小
After reading the 6th issue of “Lathe Limiter” in your magazine, I think there is still room for improvement. If the cone rod is divided into two, at the same time to prepare several different lengths of the screw and the number of different outer diameter of different thickness of the hill, to be adjusted to the desired location, with three flat nuts and tight to prevent loosening. In this way, by changing a different screw and the hilltop, you can process any cylinder with the requirements of the end of the jump. At the same time, in the pit on the car out of 2 step hole, a large step hole to reduce the contact angle, improve the terminal jump accuracy; small step hole for the boring boring knife into use. In addition, the outer diameter of the hill is only slightly smaller than the outer diameter of the workpiece, too small
