Abstract：In order to improve the assembly quality and efficiency of the engine piston ring, reduce the labor intensity, an engine piston ring assembly device suitable for the cylinder diameter of 200-250 mm was designed and applied according to the piston ring diameter and the shape of the lap, using the lever balance principle. The results show that the designed piston ring assembly device improves the installation quality of the piston ring, with low cost, simple operation and strong universality. The piston rings assembled by the device do not appear fragmentation failure, and the assembly time of a three-ring piston ring group is reduced from the original 8 min to 5 min. The device can meet the high efficiency and high quality production requirements of piston ring assembly.
