A second electric push rod is fixedly connected to the side of the moving block, and the second electric push rod is connected to the top frame. There are two second electric push rods and two moving blocks respectively. The tap is installed below the second moving block. A placement table is arranged on the top of the operating table, and a fixed seat is fixedly connected to the top of the operating table. A first hydraulic cylinder is installed inside the fixed seat, a pressing plate is fixedly connected to the side of the first hydraulic cylinder, and there are two pressing plates, first hydraulic cylinders, and fixed seats respectively. A rubber pad is fixedly connected to the side of the pressing plate. The valve casting to be processed is placed on the top of the placement table. After adjusting the position of the valve casting, the two first hydraulic cylinders are turned on. The two first hydraulic cylinders extend and drive the two pressing plates to move towards the valve casting respectively. The rubber pad contacts the valve casting, and the two pressing plates effectively clamp the valve casting. After the two first hydraulic cylinders pause, the left second electric push rod on the left side is turned on. The second electric push rod extends and drives the moving block to move to the right along the smooth shaft. The drill bit reaches directly above the position where the valve casting needs to be drilled. After the second electric push rod pauses, the driving motor is turned on. The driving motor drives the chuck and the drill bit to rotate at a high speed. The first electric push rod is turned on. The first electric push rod extends and drives the driving motor, the chuck, and the drill bit to move downward. The high-speed rotating drill bit drills the valve casting. After the drilling operation is completed, the first electric push rod contracts and runs, the driving motor stops, the second electric push rod contracts and drives the drill bit to return to the left. Subsequently, the second electric push rod on the right side is turned on. The second electric push rod extends and drives the moving block to move to the left along the smooth shaft. The tap reaches directly above the drilled hole. The first electric push rod is turned on and drives the driving motor, the chuck, and the tap to move downward. The tap reaches the drilling position. The driving motor is turned on and drives the tap to rotate. The tap performs tapping operation in the hole. After the tapping is completed, the first electric push rod contracts and runs, the driving motor stops, the second electric push rod contracts and drives the tap to return to the right. The drill bit and the tap cooperate with each other to complete the operation, saving manpower and time, improving efficiency, ensuring a stable process, and improving processing quality.

A hand wheel is fixedly connected to the top of the threaded column, and the hand wheel is inside the inner chamber. There are multiple threaded columns. Rotating the hand wheel causes the surface of the threaded column to interact with the threaded hole. When the threaded column moves downward, the rubber block contacts the ground, and the threaded column and the support foot form an effective support, effectively fixing the overall device and preventing the device from moving randomly. The multiple threaded columns further enhance the fixing effect.
