Example Embodiment

[0023] The technical solution of the present invention is further described below, but the scope of protection is not limited to the above.

[0024] Such as figure 1 As shown, an auxiliary tool for disassembly and assembly of an engine valve lock clip includes a screw 1, a fixing holder 2, a guide block 3, a pressing mechanism 4, and a bracket 5. The guide block 3 is mounted on the upper part of the bracket 5. The holder 2 is installed on the upper part of the guide block 3. The screw 1 passes through the fixed holder 2 and the guide block 3 in the vertical direction, and the lower part of the screw 1 is connected with the press-fitting mechanism 4. When in use, the nut 21 is pressed by rotating The handle 22 of the valve moves the screw 1 downwards, and the spring seat 8 is pressed by the press-fitting mechanism 4, so that the valve spring 7 is compressed. After the valve spring 8 is issued to the installation position of the valve lock clip 9, the valve lock clip can be complete...

Abstract

The invention discloses an engine valve collet dismounting and mounting auxiliary tool. The engine valve collet dismounting and mounting auxiliary tool comprises a screw, a fixing clamping base, a guiding block, a press-fitting mechanism and a support. The guiding block is mounted on the upper portion of the support. The fixing clamping base is mounted on the upper portion of the guiding block. The screw penetrates through the fixing clamping base and the guiding block in the vertical direction. The lower portion of the screw is connected with the press-fitting mechanism. A valve spring is pressed through the screw, when an heavy-duty diesel engine is maintained, the valve spring can be pressed easily, the dismounting and mounting operation of a valve collet is completed, meanwhile, the screw has the self-locking function, after pressing is completed, a maintenance man can conduct the dismounting and mounting operation with two hands, the operation efficiency is improved, the operationsafety is improved as well, the press-fitting mechanism can be adjusted according to valve rods of different types, and the application demands of the valve rods of different types can be met.

Description

technical field [0001] The invention relates to the field of engine maintenance tools, in particular to an auxiliary tool for disassembling and assembling an engine valve lock clip. Background technique [0002] At present, the valve stem of the engine is pressed against the cylinder block by a spring with great elasticity, so that the valve has sufficient airtightness to ensure the normal operation of the engine, and the locking between the spring and the valve stem is achieved by the valve lock clip. Realize that when the engine is being repaired, if the valve stem needs to be disassembled, the valve lock clip needs to be taken out by overcoming the huge elastic force of the spring, and then the valve stem can be removed. tools, such as using an ordinary sleeve to press the spring seat to overcome the elastic force, this method can be realized for light-duty diesel engines or gasoline engines, but for heavy-duty diesel engines, it is necessary to overcome the huge spring f...
