[0039] The clamping structure includes two clamping ports 13 on the storage cylinder 12. A through groove 15 is provided on the switching plate 10 near the storage cylinder 12. Two insert blocks 17 are movably inserted into the through groove 15. A limiting groove 19 is provided on the upper wall of the through groove 15.

A stabilizing block 21 is installed at the top of the fixing handle 20. A clamping block 14 is provided on the inner wall of the stabilizing block 21 and inserted into the clamping port 13. The inner arc surface of the stabilizing block 21 is pressed against the storage cylinder 12. The insert block 17 and the fixing cylinder 8 are provided with a driving structure.

[0040] The driving structure includes a fixed plate 29 fixedly sleeved on the fixed cylinder 8 near the top. A first arc-shaped groove 30 is opened on the upper edge of the fixed plate 29. A second driving groove 31 is opened on the fixed plate 29, which connects to the first arc-shaped groove 30. Two insert blocks 17 are connected to L-shaped blocks 16 at opposite ends. One end of the L-shaped blocks 16 is connected to a driving plate 27. A first driving groove 26 is opened on the driving plate 27. A horizontal groove 22 is opened below the switching plate 10. A moving block 23 is slidably arranged in the horizontal groove 22. A fixed frame 24 is installed on the moving block 23. Two first insert rods 25 are fixedly inserted through the fixed frame 24. The top of each first insert rod 25 is movably inserted into the corresponding first driving groove 26. A second insert rod 28 is connected below the moving block 23.

The bottom end of the output shaft of the second motor 46 is connected to one of the rotating rods 47. During operation, the first motor 5 on the U-shaped plate 4 drives the rotating column 6 and the rotating block 7 to rotate, thereby rotating multiple switching plates 10 and driving multiple storage cylinders 12 to switch to the loading position for loading, the milling position for processing, and the unloading position for unloading. After the core caps to be processed are loaded into the storage cylinders 12, the rotating column 6 continues to rotate, causing the bottom end of the second insertion rod 28 to slide from the second driving groove 31 into the first arc-shaped groove 30, pulling the moving block 23 in the transverse groove 22 towards the rotating column 6, and driving the fixed... One end of the first insert rod 25 on the fixed frame 24 slides in the first driving groove 26. The pressure of the first insert rod 25 against the groove wall of the first driving groove 26 causes the L-shaped block 16 to pull the two insert blocks 17 on the switching plate 10 towards each other. This causes the clamping block 14 on the stabilizing block 21 to insert into the clamping port 13, automatically clamping and fixing the core cap on the storage cylinder 12. Furthermore, the arc-shaped surface of the stabilizing block 21 fits against the storage cylinder 12, ensuring the stability of the storage cylinder 12 and the core cap during edge milling and reducing milling errors. Then, the switching plate 10 continues to move, driving the clamped core cap to the milling position. At this time, the hydraulic cylinder 44 is started to drive the lifting plate 45 to move down, and the second motor 46 is started. Under the action of the two third gears 49, the two milling discs 48 are driven to rotate to perform milling work on the core cap. After milling, the lifting plate 45 moves up to reset. Then, the rotating column 6 continues to rotate, driving the core cap to the unloading position. During this process, the bottom end of the second insertion rod 28 slides into the second driving groove 31, and the core cap is automatically released on the storage cylinder 12.

[0042] See Figures 5-9The flipping structure includes a flipping shaft 32 that rotates through one end of the switching plate 10. Flipping blocks 33 are fixedly fitted onto both ends of the flipping shaft 32. A flipping plate 11 is mounted on the top of each flipping block 33 and installed at the bottom of the storage cylinder 12.

One end of the sliding plate 37 is connected to a through strip 36 that moves through the switching plate 10. A drive frame 35 is installed on one end of the through strip 36. Teeth that mesh with the second gear 34 are provided on the inner wall of the drive frame 35. The tooth, the slide plate 37 is connected to the third insert rod 40 below, the fixed plate 29 has a second arc groove 41 on the upper side near the inside, the fixed plate 29 has a flip groove 42 that connects to the second arc groove 41, the bottom end of the third insert rod 40 is movably inserted into the second arc groove 41, during the process of the switching plate 10 driving the milled core cap to the unloading position, the bottom end of the first insert rod 25 is driven to slide from the second arc groove 41 to the flip groove 42, pulling the slide plate 37 to move towards the rotating column 6, through the through bar 36, the driving frame 35 and the second gear 34, driving the storage cylinder 12 to flip, and the core cap inside the storage cylinder 12 falls into the receiving frame 53 for automatic unloading.

[0043] See Figure 3 , Figure 4 and Figure 11 The sorting and receiving structure includes multiple support rods 50 connected to the milling table 2. The top of the support rods 50 is equipped with a receiving frame 53 through an installation structure. The receiving frame 53 is equipped with a screen plate 54 through a lifting structure.

[0044] The mounting structure includes a mounting frame 51 set at the top of the support rod 50, a mounting plate below the receiving frame 53 is movably inserted into the mounting frame 51, handles 52 are provided on both sides of the mounting frame 51, and positioning rods 55 are connected to both ends of the handles 52. One end of the positioning rod 55 is movably inserted into the positioning groove opened on the mounting plate, and a first spring 56 is sleeved on the positioning rod 55. The two ends of the first spring 56 are respectively connected to the handles 52 and the mounting frame 51.

[0045] The lifting structure includes a first through groove on one side of the receiving frame 53, an H-shaped plate 57 movably arranged in the first through groove, a sieve plate 54 fixedly installed on the H-shaped plate 57, an L-shaped rod 58 connected to the middle of one side of the H-shaped plate 57, a guide cylinder 60 movably sleeved on the L-shaped rod 58, the guide cylinder 60 being fixedly connected to the receiving frame 53 by a fixing block 59, a fixing ring 61 fixedly sleeved on the L-shaped rod 58, a second spring 62 sleeved on the L-shaped rod 58, the two ends of the second spring 62 being respectively connected to the fixing ring 61 and the guide cylinder 60, an end block 63 being provided at the bottom of the L-shaped rod 58, and a pressure ball 64 being movably embedded at the bottom of the end block 63; a transmission structure is provided on the milling table 2 near the receiving frame 53.

[0046] The transmission structure includes a fixed column 65 connected to the milling table 2. A turntable 66 is rotatably mounted on the top of the fixed column 65. A fourth gear 67 is fixedly sleeved on the turntable 66, and a first gear 9 is meshed with the fourth gear 67. The first gear 9 is fixedly sleeved on the bottom of the rotating column 6. Multiple extrusion blocks 68 are arranged at equal angles along the circumference of the upper edge of the turntable 66. One side of the extrusion block 68 is an arched surface, and the other side is a vertical surface. When the core cap is fed into the receiving frame 53, the milled core cap is collected on the screen plate 54. During the rotation of the rotating column 6... The first gear 9 and the fourth gear 67 drive the turntable 66 to rotate. When the pressing block 68 on the turntable 66 rotates onto the pressure ball 64, the arc-shaped surface of the pressing block 68 presses the pressure ball 64. The L-shaped rod 58 pushes the H-shaped plate 57 and the sieve plate 54 to move upward as a whole. When the pressing block 68 disengages from the pressure ball 64, the sieve plate 54 moves downward under the elastic force of the second spring 62. In this way, the intermittent up and down movement of the sieve plate 54 can screen the residual debris on the core cap from the sieve plate 54, thereby realizing the sorting and collection function in the collection frame 53.

[0047] The implementation principle of a valve core cap milling machine according to an embodiment of the present invention is as follows: First, the first motor 5 on the U-shaped plate 4 drives the rotating column 6 and the rotating block 7 to rotate, thereby rotating multiple switching plates 10 and driving multiple storage cylinders 12 to switch to the loading position for loading, the milling position for processing, and the unloading position for unloading. After the core cap to be processed is loaded into the storage cylinder 12, the rotating column 6 continues to rotate, driving the bottom end of the second insert rod 28 to slide from the second driving groove 31 into the first arc-shaped groove 30, pulling the moving block 23 to move towards the rotating column 6 in the transverse groove 22, and driving one end of the first insert rod 25 on the fixed frame 24 to slide in the first driving groove 26, utilizing... The compression of one end of the first insertion rod 25 against the wall of the first driving groove 26 causes the L-shaped block 16 to pull the two insertion blocks 17 on the switching plate 10 to move closer to each other. This causes the clamping block 14 on the stabilizing block 21 to insert into the clamping port 13, automatically clamping and fixing the core cap on the storage cylinder 12. The arc-shaped surface of the stabilizing block 21 fits against the storage cylinder 12, ensuring the stability of the storage cylinder 12 and the core cap during edge milling and reducing milling errors. Then, the switching plate 10 continues to move, moving the clamped core cap to the milling position. At this time, the hydraulic cylinder 44 is activated to move the lifting plate 45 downward, and the second motor 46 is activated. Under the action of the two third gears 49, the two milling plates are driven to move downward. The side plate 48 rotates to mill the core cap. After milling, the lifting plate 45 moves upward and resets. Then, the rotating column 6 continues to rotate, moving the core cap to the unloading position. During this process, the bottom end of the second insert rod 28 slides into the second driving groove 31, automatically releasing the core cap on the storage cylinder 12. The rotating column 6 also drives the bottom end of the first insert rod 25 to slide from the second arc-shaped groove 41 into the flipping groove 42, pulling the slide plate 37 towards the rotating column 6. Through the through bar 36, the driving frame 35, and the second gear 34, the storage cylinder 12 is flipped, causing the core cap inside the storage cylinder 12 to fall into the receiving frame 53 for automatic unloading. When the core cap is unloaded into the receiving frame 53... After milling, the core caps are collected on the screen plate 54. During the rotation of the rotating column 6, the first gear 9 and the fourth gear 67 drive the turntable 66 to rotate. When the pressing block 68 on the turntable 66 rotates onto the pressure ball 64, the arc-shaped surface of the pressing block 68 presses the pressure ball 64. The L-shaped rod 58 pushes the H-shaped plate 57 and the screen plate 54 to move upward as a whole. When the pressing block 68 disengages from the pressure ball 64, the screen plate 54 moves downward under the elastic force of the second spring 62. In this way, the intermittent up and down movement of the screen plate 54 can screen the residual debris on the core caps from the screen plate 54, thereby realizing the sorting and collection function in the collection frame 53. This is how the milling of the core caps is achieved.

[0048] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
