《机械工程师》2002年第6期的“调整方便的V型垫铁结构”一文介绍了对于不同直径的工件，在V型垫铁的两个斜面上配以多组不同厚度的成对垫板，可保证工件中心高度H不变，并给出了垫板厚度的加工公式。笔者通过研究，发现上述方法仍有改进的余地，具体方法如图所示。将开有V型槽 “Mechanical Engineer”, Issue 6, 2002, “Adjusting Convenient V-Horn Structure” describes how to apply pairs of shim plates of different thicknesses to two beveled surfaces of a V-shaped horn for workpieces of different diameters , To ensure that the workpiece center height H unchanged, and gives the thickness of the plate processing formula. The author through research, found that there is still room for improvement in the above method, the specific method as shown. V-groove will be opened
