Abstract

The invention belongs to the technical field of assembly and disassembly tools, and in particular relates to a assembly and disassembly tool for tappets. The dismounting tool of the tappet includes: a guide rod; a rack, the rack is arranged at one end of the guide rod; two gears, the two gears are arranged symmetrically on both sides of the rack, A plane is provided on the outside of the two gears. When the guide rod moves downward, the rack meshes with the two gears, and the plane rotates to both sides to squeeze the inner cavity. According to the disassembly and assembly tool for tappets of the present invention, by pressing the guide rod, the rack meshes with the two gears, and the planes of the two gears rotate outward at the same time to squeeze the inner cavity of the tappet, thereby realizing the alignment of the gears with the inner cavity of the tappet. The supporting function, the disassembly tool has a simple structure and stable work, which can improve the disassembly 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...
