Main oil pressure electromagnetic valve maintenance tool and using method thereof

Abstract

The invention discloses a main oil pressure electromagnetic valve maintenance tool and a using method thereof. The main oil pressure electromagnetic valve maintenance tool comprises a valve fixing base A, a valve fixing base B, a quick release sleeve, an expansion shaft, a necking sleeve and a core rod, wherein the valve fixing base A and the valve fixing base B are used for fixing a main oil pressure electromagnetic valve, the quick release sleeve is used for fixing the valve fixing base A and the valve fixing base B, the expansion shaft is used for expanding an opening of a shell of the main oil pressure electromagnetic valve, the necking sleeve is used for tightening the opening of the shell of the main oil pressure electromagnetic valve, and the core rod is used for ejecting out an internal component of the main oil pressure electromagnetic valve. A valve fixing groove A is formed inside the valve fixing base A. A valve fixing groove B is formed inside the valve fixing base. A guiding hole is formed in the center of the upper portion of the buckled structure of the valve fixing base A and the valve fixing base B. An annular clamping boss is arranged at the bottom of the inner side face of the quick release sleeve. An extending shaft is arranged at the lower portion of the expansion shaft. An annular heightening table is arranged at the upper position of the inner side of the necking sleeve. A compressing die opening is formed inside the necking sleeve. A flaring groove is formed in the lower portion of the necking sleeve. An ejector shaft is arranged on the lower end face of the core rod. The main oil pressure electromagnetic valve maintenance tool has the advantages of being simple in structure and convenient to use.

Description

technical field [0001] The present invention relates to a tool, in particular to a maintenance tool for a main oil pressure solenoid valve, and a method for using the maintenance tool for a main oil pressure solenoid valve. Background technique [0002] With the gradual improvement of the quality of life, cars have become the most important means of transportation for people in daily life. And along with the continuous improvement of automobile manufacturing technology, automatic transmission automobile becomes more popular with its simple and comfortable driving mode. But high-end vehicles have higher component costs, so the cost of replacing parts is also higher. Among them, the main oil pressure solenoid valve is also a kind of vulnerable parts, and the parts of the main oil pressure solenoid valve are small, which is not conducive to maintenance. Generally, the troubleshooting of the main oil pressure solenoid valve is to replace new parts, while the main oil pressure s...

However, high-end vehicles have higher component costs, so the cost of replacing parts is also higher

Among them, the main oil pressure solenoid valve is also a kind of vulnerable parts, and the parts of the main oil pressure solenoid valve are small, which is not conducive to maintenance. Generally, the troubleshooting of the main oil pressure solenoid valve is to replace new parts, while the main oil pressure solenoid valve The single cost of the valve is relatively high, and the single price of the main oil pressure solenoid valve on luxury models even exceeds 1,000 yuan, so the cost of replacing new parts is relatively high for car owners

In some large repair shops, there will also be repairs on the main oil pressure solenoid valve, but the maintenance method is relatively violent. Generally, the main oil pressure solenoid valve shell is violently cut and the internal components are taken out for maintenance, which leads to the failure of the main oil pressure solenoid valve. The shell cannot be reused, and it also wastes resources to a certain extent and increases maintenance costs
