| Zusammenfassung: | The invention relates to a connecting rod body and connecting rod bushing fitting degree detection method. Firstly, a spiral groove is machined in the surface of an inner hole of a connecting rod body; the connecting rod body is placed in a drying oven for heat preservation; the solid machine connecting rod bushing is placed in the liquid nitrogen until the liquid nitrogen stops boiling, the connecting rod bushing is taken out and placed in the connecting rod body, and knocking or press-in of a press machine is not allowed; standing the connecting rod body in which the connecting rod bushing is arranged at room temperature; cutting the connecting rod body by adopting a method without damaging the connecting rod bushing, and taking out the connecting rod bushing; the spiral trace line of the outer circle of the connecting rod bushing is checked, if the spiral trace line spirally extends from one end of the connecting rod bushing to the other end of the connecting rod bushing and is clear and continuous, it is |
