Abstract
This article describes processing engine connecting rod design process and fixture design process in which the main program. Engine of the technical requirements of connecting rod high, but the rigid link poor, easily deformed, so when the process in arranging, on the need to link Roughing and finishing the surface of separate processes. In order to ensure that the technical requirements of connecting rod and practical.
The big hole of connecting rod in connection with the crankshaft, the small hole of connecting rod through the piston pin hole and piston connected to the role in the expansion of the pressure of the gas piston to the crankshaft and driven by the crankshaft and piston-driven compression of gas cylinders. Connecting rod bearing high alternating load, the pressure of gas generated in the shaft a lot of compression stress and vertical bending stress. By the piston and connecting rod weight caused by the inertial force, so that connecting rod under tensile stress, so that the connecting rod to bear the impact of the nature of the dynamic load, therefore requested link light weight, strength is better.
