[0002] When the engine piston ring is manually assembled, the piston ring is usually set on the ring material column. There is an adjustment pad at the front end of the ring material column and a piston ring guide expansion mechanism. When in use, the top of the piston of the piston connecting rod assembly is pushed on the adjustment pad. Forcefully push the ring material column back, extrude the piston ring on the ring material column and fit it into the piston ring groove. The disadvantage of this method is that if the piston ring is relatively thin, it is very difficult to control the piston ring The quantity extruded from the ring material column often has several piston rings being extruded and assembled on the piston at a time, which brings inconvenience to the assembly of piston rings and affects the assembly efficiency of piston rings

The invention provides an assembly mechanism for a piston ring of an engine. A material guide device body (4) of the assembly mechanism is of a cylindrical structure, one end of the material guide device body (4) is connected with a telescopic rod part (5), and the other end of the telescopic rod part (5) is connected with a control motor (6). A pushing device (3) comprises a pushing rod (7), a press-fitting device body portion (8) of a press-fitting device (2) is of a cylindrical structure, a cavity (9) capable of installing a piston in a clamping mode is arranged at one end of the press-fitting device (2), and the cavity (9) is of a cone structure with diameter dimension gradually increasing from the press-fitting device body portion (8) to a press-fitting device end portion (10). A material guide device (1), the press-fitting device (2) and the pushing device (3) are respectively connected with a controller (11). The assembly mechanism for the piston ring of the engine can achieve automatic installation of the piston ring, improves assembly efficiency of the piston ring, and can simultaneously ensure that only one piston ring is assembled on a piston in each working process.
