[0002] The cylinder of a supercharger engine is an important key part of the engine and is also the heart of the engine. The cylinder head of the engine is composed of a cylinder cover, an air inlet (outlet) valve spring lock plate, a valve spring cover and other components, and provides combustion for the engine unit and power for the engine. According to the Supercharger Unit Maintenance and Operation Regulations, the supercharger unit is maintained annually after 8000 hours of operation. From January to October 2019, the engine cylinder head valve was dismounted and maintained 36 times.

[0003] Currently, there is no special tool technology for installing and dismounting the cylinder head valve of a supercharger engine. Each time the engine is maintained, it needs to be returned to the manufacturer for installation and dismounting. According to statistics, the average time for dismounting and taking out a set of engine cylinder head and valve is 104 minutes, and the valve accounts for 41.54% of the total dismounting operation time. SUMMARY

[0038] The specific working process of the tool for installing and dismounting the valve of the cylinder head of the supercharged engine of the embodiment of the present application is as follows: the cover is placed on the cylinder head of the engine with the mounting surface downward and compressed on the valve spring. The pushing part passes through the center hole of the cover and is connected with the spark plug sleeve through the thread at the lower end. The pushing part rotates and drives the cover to move downward to compress the valve spring and make the inner diameter of the valve locking piece gradually decrease during the process of moving downward, thereby locking the valve. The installation is completed. The cover is placed on the cylinder head of the engine with the dismounting surface downward and compressed on the valve spring. The pushing part passes through the center hole of the cover and is connected with the spark plug sleeve through the thread at the lower end. The pushing part rotates and drives the cover to move downward to compress the valve spring. The spring is contracted to make the valve locking piece loose and be taken out. The pushing part is continuously moved in the reverse direction until the valve spring and the valve are taken out. Therefore, the tool for installing and dismounting the valve of the cylinder head of the supercharged engine of the present application can meet the requirements of installing and dismounting the valve of the cylinder head of the supercharged engine on site.
