铣轴上的键槽是铣工经常遇到的加工,铣短轴上的铣槽比较容易。但对一些特别长的,且两头键槽又必须在同一直线上的轴,以及铣床行程不够长,需要二次装夹才能铣完的轴就比较困难了。为此,我们设计了一个长轴铣键槽定位环,该定位环设计制作简单,装夹使用方便,定位精度高。 1.定位环设计其结构见附图,定位环内径d_(+0.1)~(+0.2)是根据工件外径定的,定位环外径和轴向厚度可视工件情况定。尺寸S可根据下式求得:
Milling the keyway on the shaft is often encountered by the milling machine, milling the milling shaft on the minor shaft is easier. However, for some special long shafts with two keyways on the same straight line, and the mill’s stroke is not long enough, shafts that need to be clamped twice to finish milling are more difficult. To this end, we designed a long axis milling keyway positioning ring, the positioning ring design simple, easy to use clamping, high positioning accuracy. 1. Positioning ring design The structure shown in the drawings, the positioning ring diameter d _ (+0.1) ~ (+0.2) is based on the workpiece diameter set, positioning ring diameter and axial thickness of the workpiece can be determined. Size S can be obtained according to the following formula:
