S2. Second, place the workpiece on the bottom plate. Start the second motor to drive the second clamping plate to rotate to a suitable position above the workpiece. Shorten the third cylinder to drive the mounting plate to move downward, so that the second clamping plate limits and fixes the workpiece. Then, start the third motor. Drive the slider to move through the ball screw and the nut seat, thereby driving the bottom plate and the workpiece to move to the processing position. Finally, start the fourth motor. Drive the bottom plate to rotate through the second drive shaft to perform multi-sided drilling and tapping on the workpiece. S3. Finally, start the first motor. Drive the fixed sleeve to rotate through the transmission component, drive the sleeve to rotate through the first clamping plate, and then drive the drill bit to rotate. The electric telescopic column pushes the drill bit to move forward to complete the drilling and tapping of the workpiece.

[0015] The present invention integrates key components for drilling and tapping, such as motor 1, transmission assembly, fixed sleeve, sleeve, drill bit in the drilling unit, and motor 2, motor 3, motor 4 and related moving and clamping structures in the processing unit on the same machine tool. During the operation of the equipment, the various components work together, the transmission assembly ensures the stable transmission of power of the drilling unit, and the motors and moving structures of the processing unit cooperate to enable the workpiece to be accurately positioned and multi-sided processed. When applied in different working conditions, there is no need to process the workpiece between different equipment as in the traditional way, which reduces the space occupied by the equipment and the time for moving the workpiece and installing and debugging the workpiece, reduces the time loss during the workpiece transfer process, significantly improves the processing efficiency, saves workshop space, and optimizes the workshop layout.

When debugging and replacing components, start cylinder 1, splint 1 can clamp and loosen the sleeve. In actual processing, when the drill bit needs to be replaced, compared with the traditional method of using tools such as wrenches to remove multiple fastening bolts, the process is cumbersome and time-consuming. The device only needs to start cylinder 1, and the action of splint 1 can be completed within a few seconds, and then the drill bit can be quickly replaced. This greatly reduces equipment downtime for processing tasks that require frequent tool replacement, such as processing workpieces with threads of different specifications, increases the effective working time of the equipment, and significantly improves production progress.

The moving assembly composed of the motor 3, the ball screw and the nut seat can move the workpiece of different sizes to the processing position. The motor 4 drives the bottom plate to rotate, and the workpiece can be processed on multiple sides. When processing parts, the drill position can be adjusted according to the size and shape of the parts through the adjustment assembly. The flexible clamping and moving functions of the processing unit can be used to realize diversified processing. When processing large workpieces, it can withstand the weight and processing force of the large workpiece, ensure processing stability and reliability, and meet the diversified processing needs of the mechanical processing industry. No matter it is single-piece small batch production or batch production of workpieces of different specifications, the processing task can be completed efficiently and accurately.

Then, separate the drill bit 23 from the sleeve 20, and the replacement or maintenance of the drill bit 23 can be completed. S2. Next, place the workpiece 4 on the bottom plate 32. Start the second motor 35 to drive the second clamping plate 36 to rotate to a suitable position above the workpiece 4. Shorten the third cylinder 33 to drive the mounting plate 34 to move downward, so that the second clamping plate 36 limits and fixes the workpiece 4. Then start the third motor 370. Drive the slider 31 to move through the ball screw 371 and the nut seat 372, thereby driving the bottom plate 32 and the workpiece 4 to move to the processing position. Finally, start the fourth motor 373 to drive the bottom plate 32 to rotate through the second drive shaft 374 to perform multi-sided drilling and tapping on the workpiece 4; S3. Finally, start the first motor 24 to drive the fixed sleeve 26 to rotate through the transmission assembly 25. The rotation of the fixed sleeve 26 drives the rotating plate 275 that slides horizontally therewith to rotate, and also drives the limiting plate 2711 to rotate synchronously. Thus, drive the sleeve 20 to rotate through the first clamping plate 270, and further drive the drill bit 23 to rotate. The electric telescopic column 21 pushes the drill bit 23 to move forward to complete the drilling and tapping work on the workpiece 4.
