Construction machinery hydraulic cylinder is usually discarded after service cycle. The residual value can be recycled greatly by remanufacturing. Disassembly and assembly are key process in hydraulic cylinder remanufacturing. The construction machinery hydraulic cylinder disassembly and assembly equipment was developed. Hydraulic power was adopted in this equipment. The clamping and positioning of cylinder tube were realized by hydraulic clamping mechanism automatically. The piston component pulling out or into cylinder tube was realized by hydraulic working mechanism automatically. This equipment has been applied successfully in the project of “key technology and equipment for construction machinery parts remanufacturing” in a research institute. The results indicate that the application of this equipment will not only increase the automaticity and efficiency remarkably, but also reduce the damage to hydraulic cylinder key parts greatly.
