[0017] When the present invention is working, firstly, the power supply of the CNC drilling equipment is started, the CNC system starts to initialize, the status of each component is checked, and it is ensured that the equipment is in normal working condition. The feeding platform is located at the starting position of the feeding slide rail, supported by the feeding sliding block and movable on the slide rail, the workpiece quick connector assembly is in an unclamped state, the four-petal chuck is in an open position, the servo motor and the quick clamping cylinder are both in a standby state, and the worker or the automated equipment places the workpiece to be processed on the feeding platform and ensures that the workpiece is aligned with the feeding support seat. When the outer tube slides, the four-petal chuck at its inner end begins to gradually close due to the cooperation of the limit block and the limit groove, and the workpiece is tightly clamped. When the four-petal chuck is completely closed, the workpiece is firmly fixed on the workpiece quick connector assembly, and the feeding transmission rod moves along the feeding slide rail between the two groups of first limit ribs, driving the feeding platform and the workpiece thereon to move toward the processing area. When the feeding platform moves to the predetermined position, the driving motor stops working and the feeding platform stays stably.

[0018] The workpiece is first placed on the lower supporting wheel group of the lower supporting structure. The lower supporting wheel group supports the workpiece to prevent radial sliding. The feeding platform continues to move, driving the workpiece to move toward one end of the clamping and transporting unit. The workpiece is fed into the equipment and initially positioned near the clamping and transporting unit. The guide wheels on the clamping base and the multiple sets of pulleys in the clamping workbench are on standby, ready to assist in the positioning and movement of the workpiece. The clamping and clamping cylinders start working, pushing the clamping frame to move along the clamping slide rail and approach the workpiece. The clamping mechanism set on the clamping platform is also ready for clamping. The hydraulic telescopic cylinder starts and pushes the clamping block toward the workpiece through the telescopic rod until the clamping block is in close contact with the workpiece. The anti-slip groove design on the clamping block increases the friction with the workpiece and improves the stability of clamping. The clamping wheel contacts the workpiece under the push of the hydraulic telescopic cylinder and fixes the workpiece from multiple directions. After the workpiece is stably clamped, other parts of the equipment begin to perform processing operations.

[0019] Start the drilling power motor, and the motor drives the transmission mechanism in the drilling box to make the drill start to rotate. According to the set drilling depth and speed, the limit sliding cylinder controls the drill to gradually descend through the limit sliding column, contact and penetrate the spray pipe material. During the drilling process, the limit bracket and the limit platform work together to maintain the stability of the spray pipe and the linearity of the drilling. After completing the drilling of a hole of one diameter, if a drill bit of a different specification needs to be replaced, first turn off the drilling power motor to stop the drill bit from rotating, operate the manual tool changing cylinder, and use it to push or pull the rotating mounting block to make the drill bit of the required specification turn to the drilling position. After all drilling operations are completed, turn off the drilling power motor and stop the drill bit from rotating.

[0020] When the processed spray pipe is moved out of the drilling area, the discharging structure unit is ready to receive it. The discharging platform is adjusted to a position aligned with the outlet of the drilling area by the movement of the discharging sliding block on the discharging slide rail. The spray pipe is placed on the discharging platform. The tail support frame and the center frame work together to ensure that the spray pipe remains stable and horizontal on the platform. The discharging motor is started, and the motor drives the discharging transmission rod through the discharging screw rod. The discharging transmission rod is connected to the bottom of the discharging platform. As the motor rotates, the feed transmission rod slides on the screw rod, driving the discharging platform to move along the discharging slide rail. The movement of the discharging platform on the slide rail transports the spray pipe from the drilling area to the discharging port of the equipment. The center frame is located under the spray pipe to provide additional support and stability to prevent the spray pipe from sagging or shifting during transportation. When the spray pipe is transported to the discharging port and successfully taken out, the discharging motor stops working. The discharging platform returns to its initial position along the slide rail through the cooperation of the feed transmission rod and the screw rod, ready to receive the next processed spray pipe.

[0021] The beneficial effects of the present invention are embodied in the following aspects: High degree of automation and precise control: Through the integrated CNC system, the equipment realizes precise control of each process such as feeding, clamping and transportation, drilling and discharging, greatly improving the processing efficiency and accuracy. The CNC system can ensure that each processing step is carried out according to the preset program, reducing the error of human operation.

[0022] Efficient feeding and discharging system: The feeding structure unit adopts servo motor and quick clamping cylinder, and cooperates with the workpiece quick joint assembly to achieve fast and stable feeding of workpieces. At the same time, the discharging structure unit also adopts similar motor drive and slide rail design to ensure efficient and accurate discharging of workpieces.

[0023] Innovative clamping and transport mechanism: The clamping and transporting unit uses multiple sets of pulleys and guide wheels, together with the clamping and clamping cylinders and hydraulic telescopic cylinders, to achieve stable clamping and smooth transportation of the workpiece. This design not only improves the stability during processing, but also reduces damage to the workpiece caused by improper clamping.

[0024] Flexible drilling system: The drilling structure unit is equipped with multiple sets of drill bits of different specifications, and the manual tool change cylinder is used to achieve quick tool change. At the same time, the design of the limit slide rail and the counterweight hammer ensures the stability and accuracy during the drilling process, so that the equipment can meet the processing needs of sprinkler pipes of different specifications and shapes.

[0025] Safe light curtain protection: Gratings are set on the outside of the feeding structure unit and the discharging structure unit to detect whether foreign objects or people enter the processing area, thereby ensuring the safety of operators.

[0026] Enhanced undercarriage structure: The setting of the lower support structure, especially the cooperation of the lower support wheel group and the lower support telescopic cylinder, provides additional support for the long workpiece, ensuring stability and accuracy during the processing.
