The bottom output end of the driving motor is provided with a rotating shaft. The bottom of the rotating shaft is fixedly connected to a mounting seat. A drill bit is installed at the bottom of the mounting seat. An inner groove is arranged on the top of the base. A placing table is fixedly connected inside the inner groove. A second hydraulic cylinder is arranged on the side of the base. The second hydraulic cylinder reaches inside the inner groove. A pressing plate is arranged on the inner side of the second hydraulic cylinder. A rubber pad is fixedly connected to the inner side of the pressing plate. There are two second hydraulic cylinders and two pressing plates respectively. The two pressing plates are distributed on the left and right sides of the placing table. A water tank is fixedly connected to the side of the base. A water pump is arranged on the top of the water tank. The inner pipe at the bottom of the water pump reaches inside the water tank. The top of the water pump is fixedly connected to a hose. The end of the hose is fixedly connected to a fixed pipe. The fixed pipe is connected inside the lifting plate. The bottom of the fixed pipe is fixedly connected to an elbow spray pipe. The valve is placed on the top of the placing table. After adjusting the position of the valve, control the two second hydraulic cylinders to extend and operate.

The rubber pad is in direct contact with the valve to provide effective protection. Turn on the driving motor to operate. The rotating shaft rotates at a high speed. The rotating shaft drives the mounting seat and the drill bit to rotate at a high speed. Turn on the first hydraulic cylinder to extend and operate. The first hydraulic cylinder drives the lifting plate, the driving motor, the mounting seat and the drill bit to move downward. The drill bit contacts the valve and drills. At the same time, turn on the water pump. The water pump extracts the water source inside the water tank. The water flow passes through the hose and is finally sprayed out through the elbow spray pipe to cool and clean the drilling area and the drill bit. After the drilling is completed, the first hydraulic cylinder contracts and operates, driving the lifting plate, the driving motor, the mounting seat and the drill bit to move upward. The drill bit returns to its position. Pause or turn off the driving motor. The whole process provides sufficient support for conveniently placing the valve. The valve is effectively fixed to avoid displacement. The punching process is stable and the processing quality is improved.

[0005] For further improvement, a baffle is arranged on the front side of the inner groove. An activity groove is opened on the side of the base. The baffle is inserted into the activity groove.
