摘要
针对部分连杆加工后平行度和垂直度指标超差,需要进行校正处理,才能满足发动机装配要求。通过比较50只连杆在时效过程中平垂度数据采集,取一半连杆进行平垂度校正,另一半连杆未进行平垂度校正。利用统计过程控制(SPC)原理进行数据分析,验证连杆经过校正工序后,研究方法和实际结果可行有效。
In order to meet the requirements of engine assembly,the correction of the parallelism and verticality of some connecting rod is needed.By comparing the flat sag data acquisition of 50 connecting rod in the aging process,flat sag correction of half of the connecting rod is conducted,the other half of the connecting rod is not.By using the principle of Statistical Process Control（SPC）to analyze data,it is proved that the method and the actual result are feasible and effective after the connecting rod has been corrected.
