Abstract

The invention belongs to the technical field of dismounting tools, and particularly relates to a dismounting tool for a tappet. The dismounting tool for the tappet comprises a guide rod, a rack, and two gears, wherein the rack is arranged on one end of the guide rod; the two gears are symmetrically arranged on the two sides of the rack; the outer sides of the two gears are each provided with a plane; and when the guide rod moves downwards, the rack is engaged with the two gears, and each plane rotates towards the two sides to extrude the inner cavity. According to the dismounting tool for thetappet, the rack is engaged with the two gears by pressing the guide rod, and the planes of the two gears simultaneously rotate outwards to extrude the inner cavity of the tappet, so that the supporting effect of the gears on the inner cavity of the tappet is realized. The dismounting tool is simple in structure, stable in work and capable of improving dismounting efficiency of the tappet.

Description

technical field [0001] The invention belongs to the technical field of assembly and disassembly tools, and in particular relates to a assembly and disassembly tool for tappets. Background technique [0002] The tappet is the key component to realize the valve switch. The tappet is arranged between the cam and the valve, and pushes the push rod connected to the valve to move according to the motion law of the cam, thereby realizing the opening and closing of the valve. The tappets are usually arranged in the tappet holes inside the engine, and because the depth of the tappet holes is relatively deep, tools are needed when installing and dismounting the tappets. [0003] The existing tappet disassembly tool is composed of a sleeve rod, a spring and a steel ball. The spring and the steel ball are arranged at one end of the sleeve rod. The spring is used to clamp the steel ball in the tappet inner cavity. The frictional force installs or removes the tappet. Due to the point co...
