Abstract

The invention provides a fuel plunger and cap assembling tool and method.The fuel plunger and cap assembling tool comprises a fixing assembly and a torque wrench conversion assembly, and the fixing assembly comprises a base matched with a cap and a pressing plate detachably connected with the base; the torque wrench conversion assembly comprises a first torque wrench conversion sleeve matched with the fuel oil plunger and a second torque wrench conversion sleeve matched with the first torque wrench conversion sleeve. A cylindrical central through hole in which the cap can be placed is formed in the base; a central through hole matched with the bulge at the first end of the cap is formed in the pressing plate; a central through hole of the first torque wrench conversion sleeve is matched with the outward convex shape of the first end of the fuel oil plunger; and the second torque wrench conversion sleeve is provided with a central through hole in which a torque wrench can be placed. Clamping deformation of the part in the assembling process can be effectively prevented, the assembling efficiency of the part is improved, the rejection rate of the part is reduced, and cost is saved.

Description

technical field [0001] The invention relates to the field of installation of a low-speed diesel engine, in particular to the field of assembly of a fuel plunger and a cap of a fuel booster pump. Background technique [0002] The distribution block is the distribution carrier of high-pressure hydraulic oil, and the diaphragm pressure accumulator is to reduce the fluctuation of hydraulic oil inside the distribution block and is an energy storage component. When the diesel engine is running, the hydraulic main pipe distributes the high-pressure oil in the hydraulic safety block to the distribution block of each cylinder. The distribution block divides the high-pressure oil into three paths through the multi-way valve, one path is supplied to the oil injector to lubricate the piston ring in the cylinder body; the other path is supplied to the exhaust actuator, its main function is to use the high-pressure hydraulic oil provided by the distribution block as the power The hydraul...
