在机械工装、模具中常使用一些圆柱、圆锥销来导向、定位。由于铰刀的磨损和销的制造公差影响,一般过盈量往往过大。如果能将孔略扩大一些,就能解决这一问题。最简单的办法是:在比圆柱销(或圆锥销)小1～2mm的圆柱销(或圆锥销)上开一条缝(如图所示),夹在钻夹头上,将一狭条砂皮一头夹在 In the mechanical tooling, mold often use some cylindrical, tapered pins to guide, positioning. Due to the reamer wear and pin manufacturing tolerances, the general interference is often too large. If you can slightly expand the hole will be able to solve this problem. The simplest way is to make a slit (as shown) on a cylindrical pin (or conical pin) 1 ~ 2mm smaller than a cylindrical pin (or conical pin), clamp it on the drill chuck, place a strip of sand Leather in the folder
