Embodiment Construction
[0010] According to the embodiment of the present invention, it is used for the machining process of the precise reference mode of the connecting rod of the engine, and its main steps include:
[0011] ⑴First, carry out the first stage of processing before the connecting rod body and cover are cut, and then carry out rough inspection, magnetic particle inspection, and rough drilling of small head holes, and perform upper and lower end faces, small head holes, Prepare the two bolt hole end planes and the outer surface of the big head hole;
[0012] (2) Then, carry out the processing after the connecting rod body and the cover are cut, carry out the rough processing of the big head hole except the fine reference, and prepare for the rough processing of the bolt hole and the joint surface, and the processing of the locking groove of the bearing bush;
[0013] (3) Finally, carry out the processing after the connecting rod body and the cover are assembled, and then carry out the fi...
