[0004] The technical solution adopted by the present utility model to solve its technical problems: This mechanical processing drilling device includes an operation table and a drill bit. A column is fixedly connected to the top of the operation table, and a top plate is fixedly connected to the top of the column.

An inner groove is opened at the top of the operation table, a convex platform is arranged inside the inner groove, and a placement plate is installed on the top of the convex platform. The workpiece to be drilled is placed on the top of the placement plate. A first hydraulic cylinder is installed inside the top plate. There are two first hydraulic cylinders, and the two first hydraulic cylinders are distributed on the left and right sides of the electric cylinder. A first pressing block is provided at the bottom of the first hydraulic cylinder. A light shaft is fixedly connected to the top of the operation table, and the light shaft is connected to the top plate.

Activity grooves are opened on the side of the lifting plate. There are two activity grooves, and the two first hydraulic cylinders are respectively inside the two activity grooves. Make marks at the positions where the workpiece needs to be drilled. Place the workpiece on the top of the placement plate. Turn on the electric cylinder to extend and operate. The electric cylinder drives structures such as the lifting plate, the driving motor, the tool holder, and the drill bit to move downward. When the drill bit reaches the drilling mark of the workpiece, verify whether the position of the workpiece placement is accurate and make timely adjustments. Operate the electric cylinder to contract and run, driving structures such as the lifting plate, the driving motor, the tool holder, and the drill bit to return to their original positions. Turn on the two first hydraulic cylinders to extend and operate. The two first hydraulic cylinders respectively drive the two first pressing blocks to move downward. The two first pressing blocks simultaneously press the workpiece, and the workpiece is effectively fixed. Turn on the driving motor to make the rotating shaft, the tool holder, and the drill bit rotate synchronously at high speed. Turn on the electric cylinder to extend and operate again. The electric cylinder drives structures such as the lifting plate, the driving motor, the tool holder, and the drill bit to move downward. At the same time, the linear bearing and the light shaft interact with each other, and the multiple structures move downward more stably. The drill bit contacts the workpiece, and the drill bit acts on the drilling mark position. The driving motor and the electric cylinder continue to operate until the workpiece drilling is completed. Operate the electric cylinder to contract and run, driving structures such as the lifting plate, the driving motor, the tool holder, and the drill bit to return to their original positions. Then turn off the driving motor. The whole process operates quickly to fix the workpiece rapidly, saves time and manpower, improves the processing efficiency, and has strong stability to improve the processing quality.

[0005] For further improvement, through holes are opened on the surface of the lifting plate. There are multiple through holes. While increasing the strength of the lifting plate, the weight of the lifting plate is reduced, the inertia is decreased, and the stability during the lifting process is improved.

There are two second hydraulic cylinders, which are located on the front and rear sides of the inner groove. A second pressing block is arranged on the side of the second hydraulic cylinder. The two second hydraulic cylinders extend and operate, driving the two second pressing blocks to move respectively towards the center of the top of the placement plate. The two second pressing blocks effectively clamp smaller workpieces, improving flexibility to meet the clamping and fixing needs of workpieces of more sizes. Moreover, the second hydraulic cylinder can operate in cooperation with the first hydraulic cylinder to further improve the clamping and fixing effect of the workpiece.

[0008] Further improvement: A second rubber pad is fixedly connected to the side of the second pressing block. The second rubber pad is made of rubber or silica gel.

The top of the blanking hole is connected to both the central hole and multiple leakage holes at the same time, and the bottom of the blanking hole is connected to the placement groove. A storage box is arranged inside the placement groove, and the blanking hole is directly above the storage box. During the drilling process, some of the generated debris passes through the central hole and multiple leakage holes, and then falls into the storage box through the blanking hole for storage. After the drilling operation is completed, the debris on the placement plate and inside the inner groove is cleaned by sweeping left or right, and the debris directly falls into the storage box for storage. The debris is effectively collected centrally, facilitating centralized management and centralized treatment, and improving the cleanliness of the working environment.
