Abstract:With the diesel engine production transited from the traditional singlespecies, mass production to many varieties, small batch and many varieties collinear production,higher requirements have been put forward to performance of the cylinder head tighten machine.A fully automated cylinder head tightening machine design scheme was presented.The system used the whole frame structure,changeover was achieved by servo motor and rolling screw driving the tighten unit to meet the requirements of different mixedtype cylinder production line.
