Description

Novel electric hand-held piston assembly device Technical Field The invention relates to piston assembly, in particular to a novel electric hand-held piston assembly device. Background The piston is a core part of the engine, and the assembly quality directly influences the performance and the service life of the engine. At present, the piston is assembled in a manual mode in a final assembly link. During operation, a worker needs to roughly align the piston assembly with the pin hole of the piston sleeve by hand, then holds the piston sleeve by hand, and uses the hammer tool for holding the other hand to slowly knock the piston push rod (the guide rod) into the sleeve by knocking through experience until the piston assembly is installed in place. The traditional manual assembly mode relies on human eyes to observe and feel for centering, but only one hand holds the sleeve when knocking the piston, the other hand needs to hammer the piston, the body of a worker can also generate larger-amplitude movement in hammering action, the hand holding the piston sleeve is easy to shake, the piston and headache are easy to deviate, the inner wall of the piston or the sleeve is scratched, waste products are generated, the assembly quality of the manual assembly mode excessively depends on the proficiency of an operator, the consistency is poor, the process is time-consuming and labor-consuming, the production efficiency is low, and tool release injury and potential safety hazards of workers exist in repeated knocking.
