Lifting tool for piston assembly of diesel engine

The diesel engine piston assembly lifting tool comprises a lifting disc, a transverse pin, a clamping ring set and a plurality of clamping jaws, the lifting disc is located at the top end of a piston,the transverse pin transversely penetrates through the center of a cross rib plate set of the lifting disc, and the clamping ring set surrounds the upper portion of the piston in the radial direction. The lifting disc is fixedly connected with the outer edge of the upper end of the clamping ring set in the radial direction through a plurality of bolts and nuts and fixed into piston grooves in thecorresponding positions of one sides of a plurality of clamping jaws in the radial direction of the clamping ring set respectively. The piston assembly lifting tool is compact in structure and convenient to assemble, and can be used for lifting piston assemblies of various diesel engine types, the universality of the piston assembly lifting tool is improved, and the problem that an existing piston assembly lifting tool ca
