摘　　要：为了对孔系组合夹具定位方案的定位质量进行评价,首先给出工件侧定位边组合的类型和定位元件的类型,并对工件侧定位边和定位元件的组合进行定位误差的定性分析,通过确定评价定位方案定位质量的指标——误差因子,实现对定位方案定位质量的排序,最后的实例验证了方法的正确性.In order to evaluate the quality of the locating fixture, an approach is described in the paper. Firstly, the edge and the type of the locating elements are listed; combination of the locating-edge and the locating elements locating plan is determined by selecting the error factor as plan based on the dowel-pin modular type of the combination of the locating secondly, the locating error of the is analyzed; thirdly, the quality of the evaluating index; lastly, the approach is proved by some examples.
