Fuel injection pump gear drawing tool

Abstract

The invention discloses a fuel injection pump gear drawing tool, and relates to the technical field of engine auxiliary tools. The fuel injection pump gear drawing tool solves the technical problems that in the prior art, the disassembly efficiency is low and a fuel injection pump gear is easily damaged. The fuel injection pump gear drawing tool comprises a base and a drawing bolt, an inserting groove used for inserting a middle protrusion of the fuel injection pump gear is formed in the bottom of the base, a plurality of mounting holes corresponding to threaded holes of the fuel injection pump gear are formed in the base, positioning bolts are mounted in the mounting holes, the top of the base is provided with a lengthening base which is of an integrated structure with the base, a screw hole penetrating through the inserting groove is formed in the lengthening base, and the drawing bolt is installed in the screw hole; and a column body is arranged at the end of the drawing bolt, and aprotection assembly is installed on the column body. The fuel injection pump gear drawing tool is reasonable in structure, easy to operate, high in dismounting speed and high in efficiency when the fuel injection pump gear is dismounted, and the fuel injection pump gear can be prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of engine auxiliary tools, more specifically, it relates to a fuel injection pump gear drawing tool. Background technique [0002] The fuel injection pump wheel is one of the main components of the fuel injection pump. It is connected with the external crankshaft gear and plays an important role in power transmission. When there is a problem with the engine performance and needs to be repaired, it is generally necessary to disassemble the fuel injection pump, and then disassemble and repair other parts of the engine. At present, the disassembly method of the fuel injection pump wheel is mainly to use the principle of leverage, and use tools such as screwdrivers and wrenches to pry out step by step along the edge of the fuel injection pump wheel. Its disadvantages mainly include: (1) slow working efficiency. It is necessary to repeatedly pry along the outer ring of the fuel injection pump wheel, and because...

AI Technical Summary

Problems solved by technology

Its disadvantages mainly include: (1) slow work efficiency

It needs to be repeatedly pried along the outer ring of the fuel injection pump wheel, and because the fuel injection pump wheel is closely attached to the body, it can only move a small distance each time, so it is a great waste of time

(2) It is possible to damage the fuel injection pump wheel

Different models of fuel injection pumps have different tooth densities, which may be deformed when squeezed by a large force, affecting power transmission
