Abstract
A special multifunctional assembling and disassembling tool for engine valves is applied to assembling and disassembling valves and fuel injectors when engines are repaired. A handle is fixed to a small-diameter end of a cross rod. A sliding weight is sleeved on the cross rod and mainly used for disassembling the fuel injectors. A drawbar is fixed to the other end of the cross rod and fixed to the large-diameter end of the cross rod by a hinge shaft, and a drawbar joint is disposed at the lower end of the drawbar and used for fixing the tool on an engine cylinder cover. The length of the drawbar can be adjusted by means of rotating the joint so that requirements of different lengths of springs of valves in different types are met. A slide sleeve is sleeved on the cross rod, so that the distance between the drawbar of a fixing seat and a valve can be adjusted according to each of the valves in different types, and valve locking blocks can be taken out or installed conveniently. The lower portion of the slide sleeve is connected with a pressing sleeve by a connecting rod. The special multifunctional assembling and disassembling tool has the advantages that valve and fuel injector assemblies can be quickly, effectively and safely assembled and disassembled, time and labor are saved, and accidents that the springs and the locking blocks are ejected to injure people can be prevented.
