Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1-9The diagram illustrates a milling machine for automotive parts, comprising a body 1, a milling mechanism, and a protective mechanism.

The inner wall of the protective plates 7 slides against the outer wall of the milling cutter 4, and the protective plates 7 are located away from the milling cutter 4. Multiple reinforcing ribs are provided on one side to enhance the strength of the protective plate 7 and reduce the probability of it bending outward when it is pressed against by the milling cutter 4. The protective mechanism can control the position of the protective plate 7, thereby changing the exposed length of the milling cutter 4. During milling, the protective plate 7 can provide support against the side of the milling cutter 4 away from the milling surface, improving the stability of the equipment during operation. The protective mechanism also includes multiple guide rods 8 fixedly installed on the upper side of the protective plate 7. Multiple guide tubes 9 are evenly provided inside the sleeve 5.

The milling mechanism also includes two sets of side plates 35 fixedly mounted on the drive base 2. The device box 3 can slide vertically with the inner wall of the side plates 35. A spindle 36 is provided inside the drive base 2 and can rotate. A collet 37 is sleeved on one end of the milling cutter 4, and the collet 37 can be connected and fixed to the spindle 36. Connection holes 38 are provided on both sides of the device box 3. A threaded rod 13, capable of being inserted into the mounting hole 12, is threadedly connected to the side plate 35. The second threaded rod 39, which is inserted into the connecting hole 38 to achieve electrical signal connection, fixes the automotive parts to be processed inside the machine body 1. The milling cutter 4 and the sleeve 5 of appropriate size are selected and installed into the device box 3. The device box 3 is then installed on the drive seat 2. The main shaft 36 on the drive seat 2 drives the milling cutter 4 to rotate. The drive seat 2 drives the milling cutter 4 to move along the set path, thus realizing the automated milling operation of the automotive parts. During the milling process, the protective plate 7 around the milling cutter 4 is raised and lowered by the protective mechanism, so that the milling position is not blocked by the protective plate 7, while the unmilled side is supported by the protective plate 7, avoiding the milling cutter 4 from bending and breaking due to uneven force during the milling process.

[0030] Example 2: Please refer to Figures 2-10This embodiment further illustrates Embodiment 1. The control components shown in the figure include multiple sets of conveying pipes 14 fixedly installed inside the device box 3. The conveying pipes 14 store hydraulic oil. The bottom end of the conveying pipe 14 can be inserted into the bottom end of the guide pipe 9 and communicates with the top end of the guide pipe 9. A rubber tube 15 is fixedly connected to the inner wall of the top end of the guide pipe 9. The rubber tube 15 is used to improve the sealing between the inner wall of the guide pipe 9 and the outer wall of the conveying pipe 14. The device box 3 is equipped with a hydraulic component for controlling the hydraulic pressure inside the conveying pipe 14. The bottom end of the conveying pipe 14 is equipped with a sealing component, which can connect the conveying pipe 14 to the... When the guide tube 9 is connected, it controls the bidirectional flow of liquid. When the delivery pipe 14 is disconnected from the guide tube 9, the bottom end of the delivery pipe 14 automatically closes to prevent the hydraulic oil inside the delivery pipe 14 from flowing downwards. The sealing component includes a fixing ring 16 fixedly installed on the inner wall of the delivery pipe 14. A second tension spring 17 is fixedly connected to the bottom of the fixing ring 16. A lifting column 18 is slidably connected to the inner wall of the bottom end of the delivery pipe 14 in the vertical direction. The top surface of the lifting column 18 is fixedly connected to the bottom end of the second tension spring 17. Multiple sets of connecting grooves 19 are opened on the side of the lifting column 18. The connecting grooves 19 are used to connect the delivery pipe 14 and the guide tube 9. A sealing block 20 is fixedly connected to the bottom end of the lifting column 18 and the pipe 9. A rubber sealing ring is provided on the upper side of the sealing block 20. The outer diameter of the sealing block 20 is smaller than the inner diameter of the rubber tube 15 and larger than the inner diameter of the conveying pipe 14. A limiting component for controlling the position of the lifting column 18 is provided inside the lifting column 18. The limiting component includes a snap-fit ​​block 21 that slides horizontally with the inner wall of the lifting column 18. A snap-fit ​​groove 22 is provided on the inner wall of the conveying pipe 14, which can snap into one end of the snap-fit ​​block 21. The cross-section of the snap-fit ​​groove 22 is triangular. A spring 23 is fixedly connected to the end of the snap-fit ​​block 21 away from the snap-fit ​​groove 22. Spring 23 is fixedly connected to the inner wall of lifting column 18. The lifting state of multiple sets of protective plates 7 is controlled by hydraulic components. When pressure is applied to the guide tube 9, the guide rod 8 drives the protective plate 7 to move down, and vice versa, the protective plate 7 slides up. During single-sided milling, the protective plate 7 away from the milling side moves down, and the protective plate 7 close to the milling side moves up. During drilling, the lifting and lowering of multiple sets of protective plates 7 are controlled synchronously according to the drilling depth, reducing the exposed area of ​​the milling cutter 4, improving the stability of the milling cutter 4 during operation, reducing the vibration of the milling cutter 4, improving the accuracy of milling, and extending the service life of the milling cutter 4.

[0031] Example 3: Please refer to Figures 1-10This embodiment further illustrates Embodiment 1. The hydraulic components shown in the figure include multiple sets of hydraulic cylinders 24 fixedly installed inside the device box 3. The number of hydraulic cylinders 24 is the same as the number of conveying pipes 14 and protective plates 7. The end of the conveying pipe 14 away from the guide pipe 9 is connected to the top of a set of hydraulic cylinders 24. Multiple sets of electric telescopic rods 25 are fixedly connected inside the device box 3. The telescopic ends of the electric telescopic rods 25 are fixedly connected to hydraulic plates 26 that slide against the inner wall of the hydraulic cylinders 24. An adjusting component is provided inside the device box 3. The adjusting component is used to balance the hydraulic pressure in the multiple sets of hydraulic cylinders 24 when replacing the sleeve 5. The top of the guide pipe 9 is provided with... A vent valve is provided to allow gas to escape while preventing hydraulic oil from overflowing. This allows residual gas inside the guide pipe 9 to be released when hydraulic oil is injected into the guide pipe 9 from the delivery pipe 14. The adjusting component includes a storage box 27 fixedly installed inside the device box 3. The storage box 27 is annular, and a connecting pipe 28 is connected to the side of the hydraulic cylinder 24. Multiple sets of first through holes 29 are evenly provided on the inner wall of the storage box 27, which can communicate with the connecting pipe 28. A rotating ring 30 is rotatably connected to the inner wall of the storage box 27. The inner wall of the rotating ring 30 is rotatably fitted with one end of the connecting pipe 28. The two sides of the rotating ring 30 can connect the first through holes 29 and the connecting pipe. 28 is sealed. Multiple sets of second through holes 31 are evenly distributed on the rotating ring 30, connecting to the first through hole 29 and the connecting pipe 28. The number of first through holes 29, second through holes 31, and connecting pipes 28 are equal. The device box 3 is equipped with a drive component for controlling the rotation of the rotating ring 30. The drive component includes a drive ring 32 fixedly installed at the bottom of the rotating ring 30. A control groove 33 is provided on the side of the device box 3. A limit block 34 is fixedly connected to the outer wall of the drive ring 32, and the limit block 34 is located within the control groove 33. When the guide rod 8 moves to its highest position, the top of the guide rod 8 pushes the lifting column 18 upward, thus moving the conveying pipe 14... With the bottom sealed, the guide tube 9 will still contain a small amount of hydraulic oil. If the sleeve 5 is removed directly and the next set of sleeves 5 is installed, there will be no hydraulic oil in the guide tube 9 inside the sleeve 5. When the delivery pipe 14 is connected to the guide tube 9, some hydraulic oil needs to be input into the gap inside the guide tube 9, which will reduce the total amount of hydraulic oil in the hydraulic cylinder 24 and the delivery pipe 14. Over time, this will result in a serious shortage of hydraulic oil inside, affecting the control accuracy of the protective plate 7 position. Therefore, it is necessary to replenish the hydraulic oil inside the hydraulic cylinder 24 and the delivery pipe 14 each time the sleeve 5 is replaced.

[0032] Working principle: Select a suitable size milling cutter 4 and socket 5. The outer wall size of different models of socket 5 is fixed and can be inserted into the insertion hole 6. Insert the milling cutter 4 into the socket 5 so that the inner wall of the protective plate 7 fits against the outer wall of the milling cutter 4. Then insert the socket 5 into the insertion hole 6. The top of the milling cutter 4 passes through the device box 3. The top of the milling cutter 4 is fixed at the top by the collet 37. Rotate the first threaded rod 13 and insert it into the mounting hole 12 to fix the socket 5. At this time, the bottom end of the conveying pipe 14 is automatically inserted and connected to the inner wall of the rubber tube 15 at the top of the guide pipe 9. Then slide the entire device box 3 from bottom to top between the two sets of side plates 35. The position allows the collet 37 to be inserted into the structure at the bottom of the spindle 36 and tightened by the threaded ring. Then, the second threaded rods 39 on both sides are screwed into the connecting holes 38 on both sides of the device box 3 to complete the fixation. The electrical signal can be transmitted to the device box 3 through the contact between the second threaded rods 39 and the connecting holes 38 (there are wires in the connecting holes 38 and the second threaded rods 39, which can achieve communication during the contact process). After that, the milling cutter 4 can be rotated and milled by the drive seat 2. At the same time, the drive seat 2 on the machine body 1 can be moved and adjusted in multiple directions, so that the milling cutter 4 can move and process along the required path.

[0033] During the milling process, the operating status of multiple sets of electric telescopic rods 25 is controlled according to the pre-set milling program. In the initial state, the electric telescopic rods 25 are in the retracted state, and the hydraulic oil is fully recovered into the hydraulic cylinder 24. When it is necessary to control the protective plate 7 to move downward, the electric telescopic rod 25 on that side is controlled to push the hydraulic plate 26 upward, squeezing the hydraulic oil into the conveying pipe 14, pushing the lifting column 18 downward, and the locking block 21 is locked into the locking groove 22 to complete the initial limiting. The second tension spring 17 is stretched. At this time, the connecting groove 19 connects the conveying pipe 14 and the guide pipe 9. During the pressurization process of pipe 14, hydraulic oil flows into guide pipe 9, pushing guide rod 8 and protective plate 7 downward. During the depressurization process of delivery pipe 14, the first tension spring 11 pulls back, and hydraulic oil flows in reverse from connecting groove 19 into delivery groove. Guide rod 8 and protective plate 7 move upward, which can flexibly control the lifting state of multiple sets of protective plates 7, so that the exposed end mill 4 on the side away from the milling surface can be supported by the protective plate 7, reducing the risk of end mill 4 bending. Multiple sets of electric telescopic rods 25 are independently controlled, which can flexibly adjust the lifting state of protective plate 7 according to the change of milling position.

[0034] When the milling cutter 4 needs to be replaced, control the electric telescopic rod 25 to pull back to its lowest point, and the guide rod 8 and protective plate 7 move to their highest point. At this time, the top of the guide rod 8 will push the bottom surface of the lifting column 18, causing the lifting column 18 to move upward. The locking block 21 will release from the locking groove 22. The second tension spring 17 will drive the lifting column 18 to pull back to the inside of the conveying pipe 14. The sealing block 20 and the rubber sealing ring will block the bottom of the conveying pipe 14 to prevent hydraulic oil from overflowing downward. Remove the sleeve 5 and the milling cutter 4 from the device box 3, select a suitable sleeve 5 and the milling cutter 4, reinstall them in the device box 3 and fix them. Start the electric telescopic rod 25 to push a distance, allowing the lifting column 18 to move downward, connecting the conveying pipe 14 and the guide pipe 9. At the same time, hydraulic oil will be input into the guide pipe 9 to expel the air in the guide pipe 9. Then, control the electric telescopic rod 25 to retract a distance to the set position. The guide rod 8 will not lift the lifting column 18, but will keep the internal pressure of the hydraulic cylinder 24 relatively low. At this time, the limit block 34 needs to be moved so that it slides to the other end of the control groove 33. The limit block 34 drives the drive ring 32 to rotate the rotating ring 30 by a set angle. The second through hole 31 rotates to the position where it connects with the first through hole 29 and the connecting pipe 28. The hydraulic oil in the storage box 27 can then be drawn into the hydraulic cylinder 24, which completes the reset. Each time the hydraulic oil is replaced, a hydraulic oil reset operation needs to be performed to ensure that the hydraulic pressure inside the hydraulic cylinder 24 is relatively stable. This allows for precise control of the lifting accuracy of the protective plate 7 in subsequent control. After the adjustment is completed, the limit block 34 is rotated in the opposite direction to disconnect the connection between the second through hole 31 and the first through hole 29. The two sides of the rotating ring 30 then block the first through hole 29 and the connecting pipe 28, respectively.
