摘　　要：对镗模夹具中凸轮孔导向座的结构形式、热处理、加工后检测关键孔的同轴度、圆柱度超差原因进行了全面分析。分析表明,结构形式复杂、热处理变形是导致超差的主要因素。通过改善加工工艺、热处理方式以及加强结构强度的方法,避免了加工变形、热处理变形。实践证明,这种工艺方法能够保证产品的加工质量,使用效果很好。The paper analyzed the structure of cam hole guide base, heat treatment, and the cause of coaxiality and cyIindricity deviation of key holes. The analysis results show complex structure and heat treatment distortion are the main factors of deviation. The machining distortion and heat treatment distortion can be avoided by improving the processing technic and heat treatment mode, and strengthening the structure strength. The practice proves that this method can guarantee the quality of products, and the using effect is very good.
