[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example 1:

[0020] like Figures 1 to 10 As shown, a spinning screw rotary milling device includes a working area 2, a debris collection hopper 3 at the bottom of the working area 2, a control system 1 at one end of the working area 2, a clamping system 4 on the control system 1, a spinning screw 5 clamped on the clamping system 4, and a processing area 6. The working area 2 also includes a drive system 14, a connecting plate 15 at the output end of the drive system 14, a servo motor 17 on the connecting plate 15, and a rotary milling assembly 18 at the output end of the servo motor 17. The rotary milling assembly 18 is used to process the spinning screw 5. The working area 2 also includes a grinding assembly 13 and a placement plate 9. A water tank 10 is located on one side wall of the placement plate 9, and a connecting pipe 38 is located on the water tank 10. A nozzle is located on the connecting pipe 38. The placement plate 9 also includes an installation sleeve 35, and a brush 36 is located on the installation sleeve 35. The brush 36 and the nozzle are used to process the spinning screw 5. The control system 1 provides overall control, and together with the clamping system 4, it securely fixes the spinning screw 5, ensuring processing stability and accuracy. The rotary milling assembly 18, driven by the drive system 14 and the servo motor 17, processes efficiently and has strong adaptability. The debris collection hopper 3 at the bottom of the working area 2 facilitates the centralized collection of debris, keeping the working environment clean. The water tank 10 on the side of the placement plate 9 sprays water through the connecting pipe 38 and the nozzle, and with the help of the brush 36 on the mounting sleeve 35, it thoroughly removes debris from the surface of the workpiece, laying the foundation for subsequent processes. The grinding assembly 13 grinds the workpiece after cleaning, avoiding scratches caused by debris and significantly improving the product qualification rate.

[0021] like Figures 1 to 5 and Figures 7 to 8 as well as Figure 10 As shown, in a specific embodiment, two electrically controlled slide rails 8 are provided on one side wall of the working area 2. A mounting plate 7 is slidably mounted on the two electrically controlled slide rails 8, and a drive system 14 is slidably mounted on the mounting plate 7. In this configuration, the dual electrically controlled slide rails 8 provide stable horizontal movement guidance for the mounting plate 7, allowing for precise adjustment of the lateral position of the drive system 14 and the rotary milling assembly 18, achieving rapid positioning before machining and improving machining position accuracy.

[0022] like Figures 1 to 5 and Figures 7 to 8 as well as Figure 10 As shown, the mounting plate 7 is further provided with two telescopic rods 16, with one end of each telescopic rod 16 away from the mounting plate 7 mounted on the connecting plate 15. In this configuration, the telescopic rods 16 cooperate with the drive system 14 to provide bidirectional guiding and limiting for the movement of the connecting plate 15, preventing the rotary milling assembly 18 from shifting or shaking during machining, and ensuring the stability and machining accuracy of the rotary milling cut.

[0023] like Figures 1 to 5 and Figures 7 to 8 as well as Figure 10 As shown, further, a connecting plate 19 is placed at the bottom of the connecting plate 15. A fixed bearing 20 is provided on the front side of the connecting plate 19. A rotating rod 21 is provided on the fixed bearing 20. A C-shaped sleeve 31 is provided at the end of the rotating rod 21 away from the fixed bearing 20. A fixed seat 22 is also provided on the rotating rod 21. A wedge block 23 is provided at the bottom of the fixed seat 22. An inclined surface 24 is provided on the wedge block 23. In this configuration, the connecting plate 19 realizes the power transmission between the connecting plate 15 and the rotating rod 21. The wedge block 23 converts the horizontal movement of the connecting plate 15 into the lateral driving force of the limiting plate 29 through the inclined surface 24, providing the power basis for the engagement action of the C-shaped sleeve 31, and realizing the linkage of the processing and cleaning processes.

[0024] like Figures 1 to 5 and Figures 7 to 8 as well as Figure 10 As shown, a circular mounting plate 26 is further provided on the rotating rod 21, and a sliding block 28 is provided on the circular mounting plate 26. A limit plate 29 is provided on one side wall of the sliding block 28. In this configuration, the sliding block 2 is driven by a driving force, thereby providing a guiding limit for the rotation of the rotating rod 21, ensuring that the movement trajectory of the rotating rod 21 when it drives the C-shaped ferrule 31 is accurate, ensuring that the C-shaped ferrule 31 and the clamping plate 40 quickly and accurately fit together, and improving the reliability of the process linkage.

[0025] like Figures 1 to 5 and Figures 7 to 8 as well as Figure 10As shown, furthermore, two guide rods 25 are symmetrically arranged on the limiting plate 29, and each end of the guide rod 25 is provided with a placement seat 30, which is located on the processing area 6. In this configuration, the double guide rods 25 provide a stable horizontal movement trajectory for the limiting plate 29, limit the vertical offset of the limiting plate 29, ensure that the limiting plate 29 moves smoothly when driven by the wedge block 23, and thus ensure the positioning accuracy of the C-shaped ferrule 31.

[0026] like Figures 1 to 5 and Figures 7 to 8 as well as Figure 10 As shown, the rotating rod 21 is further equipped with a movable plate 32, and the movable plate 32 is equipped with a movable block 33. The movable block 33 has an inclined surface 34, which is used to squeeze the connecting pipe 38. In this configuration, when the inclined surface 34 of the movable block 33 moves with the rotating rod 21, it squeezes the connecting pipe 38, which can realize the automatic triggering of water spraying and water volume adjustment, so that the water spraying action is synchronized with the brush cleaning, without the need for additional control commands, thus simplifying the process. Example 2:

[0027] The difference between the above embodiments and this embodiment is that: Figures 1 to 5 and Figures 7 to 8 as well as Figure 10 As shown, a spinning screw rotary milling device includes a limiting rod 39 on a placement plate 9. A clamping plate 40 is located at the end of the limiting rod 39 furthest from the placement plate 9. The clamping plate 40 and a C-shaped retainer 31 engage with each other. Two symmetrical L-shaped slide rails 37 are also provided at the bottom of the placement plate 9. The L-shaped slide rails 37 provide horizontal movement guidance for the placement plate 9, preventing it from shifting. The engaging structure of the clamping plate 40 and the C-shaped retainer 31 ensures stable power transmission, allowing the placement plate 9 to drive the brush 36 to precisely adhere to the workpiece, improving the comprehensiveness of debris removal.

[0028] like Figures 1 to 5 and Figures 7 to 8 as well as Figure 10 As shown in the specific embodiment, the working area 2 is further provided with two mounting plates 7, which are symmetrical to each other. Each of the two mounting plates 7 has an electric slide rail 12 on one opposite side wall, and the two electric slide rails 12 are symmetrical to each other. A grinding component 13 is slidably mounted on the two electric slide rails 12. In this configuration, the symmetrically distributed electric slide rails 12 drive the grinding component 13 to move smoothly up and down in the vertical direction, ensuring uniform contact between the grinding component 13 and the workpiece surface, avoiding grinding dead angles, and improving the smoothness of the workpiece surface. Example 3:

[0029] This invention also discloses a spinning screw rotary milling process, the steps of which are as follows: Step 1: Place the spinning screw 5 on the clamping system 4, and control the clamping system 4 to clamp the workpiece through the control system 1; start the electric slide rail 8 to drive the mounting plate 7 to move, so that the rotary milling assembly 18 is initially close to the processing area 6, and complete the pre-processing positioning preparation; Step 2: Drive the spinning screw 5 to rotate through the control system 1, start the servo motor 17 to drive the rotary milling assembly 18 to operate; control the drive system 14 to push the connecting plate 15, and under the guidance of the telescopic rod 16, make the rotary milling assembly 18 fit against the workpiece to perform rotary milling on the spinning screw 5. Step 3: After machining is completed, the control drive system 14 runs in reverse, driving the rotary milling assembly 18 to retract the tool; the connecting plate 15 drives the connecting plate 19 and the rotating rod 21 to move, and the wedge block 23 drives the limiting plate 29, so that the C-shaped sleeve 31 engages with the clamping plate 40. Step 4: The C-shaped sleeve 31 moves the limiting rod 39, so that the brush 36 on the placement plate 9 fits the workpiece; the water tank 10 pumps water, which sprays water through the connecting pipe 38 and the nozzle, and cleans up the debris in conjunction with the rotation of the workpiece. Step 5: Control the electric slide rail 12 to drive the grinding component 13 to move down and grind the cleaned spinning screw 5; after grinding, the clamping system 4 releases the workpiece, the equipment resets, the workpiece is removed, and the debris is collected through the debris collection hopper 3.

[0030] The implementation principle of the spinning screw rotary milling device of the present invention is as follows: First, when performing spin milling on the spinning screw, the operator needs to first place the spinning screw 5 on the machine, and then clamp the spinning screw 5 using the clamping system 4. After clamping, the operator can control the drive system 14 to run, so that the drive system 14 can drive the connecting plate 15 to move horizontally, thus driving the servo motor 17 and the spin milling assembly 18 to move, so that the spin milling assembly 18 can get closer to the spinning screw 5. Then, the operator rotates the spinning screw 5 through the drive control system 1 and drives the servo motor 17 to run, so that the servo motor 17 can drive the blade of the rotary milling assembly 18 to rotate, thus enabling the rotary milling assembly 18 to process the spinning screw 5. After machining is completed, the tool needs to be retracted. Therefore, the operator controls the drive system 14 to run in reverse, which drives the connecting plate 15, the servo motor 17 and the rotary milling assembly 18 to move and complete the tool retraction. During the retraction process, the drive system 14 drives the connecting plate 15 to move outward, and when the connecting plate 15 moves, it can drive the connecting plate 19 to move. When the connecting plate 19 moves, it can drive the rotating rod 21 to move, and thus drive the C-shaped sleeve 31 to move. When the C-shaped sleeve 31 moves, it can drive the clamping plate 40 to move, and thus drive the limiting rod 39 to move through the clamping plate 40, so that the placement plate 9 can move, allowing the brush 36 to adhere to the spinning screw 5. Therefore, when the spinning screw 5 continues to rotate, it can clean the processed spinning screw 5 through the brush 36. At the same time, by controlling the water pump in the water tank 10, water can be drawn and sprayed onto the spinning screw 5 through the connecting pipe 38 and the nozzle, thus rinsing the spinning screw 5 and ensuring to a certain extent that there are no debris on the spinning screw 5. At this time, the electric slide rail 12 is controlled to run and drive the grinding component 13 to move down, so that the grinding component 13 can grind the spinning screw 5 after processing and extrusion cleaning, ensuring that the workpiece will not be scrapped due to large debris during the grinding process. Simultaneously, it can also drive the fixed seat 22 and wedge block 23 to move, so that the wedge block 23 can press the limiting plate 29 through the inclined surface 24, and the limiting plate 29 can move horizontally with the assistance of the guide rod 25. When the limiting plate 29 moves, it can press the sliding block 28 to move with the assistance of the guide rod 25, so that the circular mounting plate 26 can rotate with the assistance of the rotating rod 21. When the rotating rod 21 rotates, it can drive the C-shaped sleeve 31 to rotate, so that the C-shaped sleeve 31 can move away from the side of the clamping plate 40. Thus, when the rotary milling assembly 18 completes the retraction, the control of the electronically controlled slide rail 8 drives the mounting plate. 7, the drive system 14, and the rotating rod 21 can move horizontally, allowing the C-shaped ferrule 31 to separate from the clamping plate 40, keeping the mounting plate 7 in place, thus facilitating subsequent adjustment of the tool position (the initial position for normal processing is the position shown in the figure); at the same time, the moving block 33 will rotate, causing the inclined surface 34 to leave the connecting pipe 38, allowing the connecting pipe 38 to slowly reset itself in the left and right directions of its own material (the specific material is existing technology), which facilitates subsequent direct cleaning of the processed spinning screw (the inner cavity of the fixed seat 22 is provided with a circular slide rail, and the circular slide rail is slidably set with the rotating rod 21).
