Specific embodiments

[0030] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0031] Embodiment 1, refer to Figures 1-6, A tool sleeve flipping device for a chain belt type tool magazine, including a frame body 1. A driving chain belt 2 is arranged inside the frame body 1, and a plurality of swing plates 4 are arranged at equal intervals on the driving chain belt 2. One end of the swing plate 4 is fixedly connected with a tool sleeve 3, and a reverse knife wheel 5 is arranged at the other end of the swing plate 4. A reverse knife cylinder 9 is arranged outside the driving chain belt 2, and a reverse knife block 10 is fixedly connected to the telescopic end of the reverse knife cylinder 9. A storage tank 7 is arranged on one side of the reverse knife cylinder 9, and lubricating oil is stored in the storage tank 7. An oil squeezing tank 8 is arranged between the storage tank 7 and the reverse knife cylinder 9, and a connecting pipe 6 is connected between the top end of the oil squeezing tank 8 and the bottom end of the storage tank 7. A spray pipe 13 is fixedly connected to the inner wall of the top of the reverse knife block 10, and a plurality of spray nozzles 14 are arranged at equal intervals on the outer wall of the bottom of the spray pipe 13. A horn pipe 11 is arranged on the outer wall of the oil squeezing tank 8, and the narrow end of the horn pipe 11 is communicated with the outer wall of the oil squeezing tank 8. A telescopic pipe 12 is connected between the wide end of the horn pipe 11 and one end of the spray pipe 13. An oil squeezing mechanism is arranged at one end of the oil squeezing tank 8, and a sealing mechanism is arranged inside the oil squeezing tank 8. The driving chain belt 2 in the frame body 1 can move a plurality of tool sleeves 3, and can move the tool sleeve 3 to be flipped to a specified position. At this time, the reverse knife wheel 5 on the swing plate 4 is stuck in the reverse knife block 10. Then the reverse knife cylinder 9 is started to make the reverse knife block 10 move away from the reverse knife cylinder 9, so that the tool sleeve 3 can be flipped, and then the tool is replaced. When the replacement is completed, the reverse knife cylinder 9 makes the reverse knife block 10 approach the reverse knife cylinder 9 until the tool sleeve 3 is reset, and finally the tool change work is completed. In the above process, the reverse knife cylinder 9 pumps the lubricating oil in the storage tank 7 into the oil squeezing tank 8 through the oil squeezing mechanism, and then the lubricating oil in the oil squeezing tank 8 enters the spray pipe 13 through the telescopic pipe 12, and finally through the plurality of spray nozzles 14 under the spray pipe 13, the lubricating oil is sprayed onto the reverse knife wheel 5 stuck in the reverse knife block 10 to lubricate the inner wall of the reverse knife wheel 5 and the reverse knife block 10, without manual lubrication, greatly reducing the friction between the reverse knife wheel 5 and the inner wall of the reverse knife block 10, and avoiding jamming or abnormal noise.

[0032] As a further scheme in the present invention, the oil squeezing mechanism includes a piston plate 20, the piston plate 20 is hermetically and slidably connected inside the oil squeezing tank 8, and a hollow slide bar 21 is slidably connected to one side of the oil squeezing tank 8. One side of the hollow slide bar 21 is fixedly connected with the piston plate 20, and the other side of the hollow slide bar 21 is slidably connected with a connecting rod 22.

[0033] As a further solution in the present invention, a limiting plate 23 is fixedly connected to one side of the connecting rod 22, and the limiting plate 23 is slidably connected to the inside of the hollow sliding rod 21. A connecting block 15 is fixedly connected to the other side of the connecting rod 22, and the connecting block 15 is fixedly connected to the outer wall of the inverted cutter block 10. During the process of the cutter sleeve 3 being flipped by the inverted cutter cylinder 9, the connecting rod 22 will be synchronously moved through the connecting block 15. The connecting rod 22 moves the limiting plate 23 in the hollow sliding rod 21, so that the limiting plate 23 moves from one side inside the hollow sliding rod 21 to the other side until the limiting plate 23 abuts against the inner wall of the other side of the hollow sliding rod 21, thereby enabling the hollow sliding rod 21 on the oil squeezing tank 8 to move. The hollow sliding rod 21 moves the piston plate 20 in the oil squeezing tank 8. At this time, the sealing mechanism makes the connecting pipe 6 no longer sealed and makes the horn pipe 11 sealed. Under the action of the internal and external air pressure difference, the lubricating oil in the storage tank 7 enters the oil squeezing tank 8 through the connecting pipe 6; during the process of the cutter sleeve 3 resetting, the piston plate 20 squeezes the lubricating oil in the oil squeezing tank 8. At this time, the sealing mechanism seals the connecting pipe 6, and the horn pipe 11 is not sealed. Therefore, the lubricating oil in the oil squeezing tank 8 is squeezed into the telescopic pipe 12 and then enters the injection pipe 13.

[0034] As a further solution in the present invention, the sealing mechanism includes a fixing plate 16. The fixing plate 16 is fixedly connected to the inside of the oil squeezing tank 8, and two elastic telescopic rods 17 are symmetrically and fixedly connected to the outer wall of the fixing plate 16 close to the connecting pipe 6. The same sealing plate 18 is fixedly connected to the same ends of the two elastic telescopic rods 17, and the sealing plate 18 seals the connecting pipe 6 under the action of the two elastic telescopic rods 17.

[0035] As a further solution in the present invention, a sealing ball 24 is arranged inside the horn pipe 11, and a connecting spring 19 is fixedly connected to the bottom of the sealing ball 24. The bottom end of the connecting spring 19 passes through the horn pipe 11, the oil squeezing tank 8 and is fixedly connected to the fixing plate 16. When the cutter sleeve 3 is flipped, the piston plate 20 in the oil squeezing tank 8 moves away from the fixing plate 16. Under the action of the internal and external air pressure difference, the sealing plate 18 compresses the elastic telescopic rod 17 and moves away from the connecting pipe 6. Therefore, the sealing plate 18 does not seal the connecting pipe 6, and the sealing ball 24 in the horn pipe 11 seals the horn pipe 11. Thus, the lubricating oil in the storage tank 7 enters the oil squeezing tank 8 through the connecting pipe 6; when the cutter sleeve 3 resets, the piston plate 20 approaches the fixing plate 16 and squeezes the lubricating oil. At this time, the sealing plate 18 is in close contact with the inner wall of the oil squeezing tank 8, and the sealing plate 18 seals the connecting pipe 6. The lubricating oil does not enter the connecting pipe 6 but enters the horn pipe 11, thereby pushing the sealing ball 24 open and making the sealing ball 24 no longer seal the horn pipe 11. The lubricating oil enters the telescopic pipe 12 through the horn pipe 11.

[0036] Working principle: The driving chain belt 2 in the frame 1 can move multiple tool holders 3, and can move the tool holder 3 that needs to be flipped to a specified position. At this time, the reverse cutter wheel 5 on the swing plate 4 is stuck in the reverse cutter block 10. Then, the reverse cutter cylinder 9 is started, so that the reverse cutter block 10 moves away from the reverse cutter cylinder 9, so that the tool holder 3 can be flipped, and then the tool is replaced. During the flipping process of the tool holder 3, the reverse cutter block 10 will drive the connecting rod 22 to move synchronously through the connecting block 15. The connecting rod 22 moves the limiting plate 23 in the hollow slide rod 21, so that the limiting plate 23 moves from one side inside the hollow slide rod 21 to the other side until the limiting plate 23 abuts against the inner wall on the other side of the hollow slide rod 21, so that the hollow slide rod 21 on the oil squeezing tank 8 can move. The piston plate 20 in the oil squeezing tank 8 will move away from the fixed plate 16. Under the action of the internal and external air pressure difference, the sealing plate 18 compresses the elastic telescopic rod 17 and moves away from the connecting pipe 6, so that the sealing plate 18 does not seal the connecting pipe 6, and the sealing ball 24 in the horn pipe 11 seals the horn pipe 11, so that the lubricating oil in the storage tank 7 enters the oil squeezing tank 8 through the connecting pipe 6; when the replacement is completed, the reverse cutter cylinder 9 makes the reverse cutter block 10 approach the reverse cutter cylinder 9 until the tool holder 3 is reset, and the tool changing work is completed. During the reset process of the tool holder 3, the piston plate 20 in the oil squeezing tank 8 will approach the fixed plate 16 and squeeze the lubricating oil. At this time, the sealing plate 18 is closely attached to the inner wall of the oil squeezing tank 8, and the sealing plate 18 seals the connecting pipe 6. The lubricating oil will not enter the connecting pipe 6 but will enter the horn pipe 11, so as to push the sealing ball 24 away, so that the sealing ball 24 no longer seals the horn pipe 11. The lubricating oil enters the telescopic pipe 12 through the horn pipe 11, and finally through multiple nozzles 14 under the spraying pipe 13, the lubricating oil is sprayed onto the reverse cutter wheel 5 stuck in the reverse cutter block 10 to lubricate the inner wall of the reverse cutter wheel 5 and the reverse cutter block 10, without manual lubrication, greatly reducing the friction between the reverse cutter wheel 5 and the reverse cutter block 10 and avoiding jamming or abnormal noise.

[0037] Embodiment 2, referring to Figures 1-8 , a tool holder flipping device for a chain belt type tool magazine. Compared with Embodiment 1, on the basis of Embodiment 1, a second rotating shaft 30 is hermetically and rotatably connected to the outer wall of the storage tank 7, and a plurality of driving rods 25 are fixedly connected to one end of the second rotating shaft 30 at equal intervals. The other end of the second rotating shaft 30 is fixedly connected to a second bevel gear 29. When the driving chain belt 2 drives multiple tool holders 3 to move, the driving rod 25 will intermittently contact the swing plate 4 and the reverse cutter wheel 5 on the tool holder 3, so that the second rotating shaft 30 will be rotated by the driving rod 25, and the second rotating shaft 30 will synchronously rotate the second bevel gear 29.

[0038] As a further solution in the present invention, a first rotating shaft 26 is rotatably connected inside the storage box 7, and a plurality of stirring rods 27 are fixedly connected to the outer wall of the first rotating shaft 26 at equal intervals. A first bevel gear 28 is fixedly connected to the outer wall above the first rotating shaft 26, and the first bevel gear 28 meshes with a second bevel gear 29. Since the second bevel gear 29 meshes with the first bevel gear 28 on the outer wall of the first rotating shaft 26, the plurality of stirring rods 27 on the outer wall of the first rotating shaft 26 can be rotated to stir the lubricating oil in the storage box 7, keeping the lubricating oil in a moving state at all times, and preventing the lubricating oil from precipitating after being stored for too long and affecting the lubrication effect.

[0039] Working principle: When the drive chain belt 2 drives a plurality of tool sleeves 3 to move, the drive rod 25 will intermittently contact the swing plate 4 and the reverse cutter wheel 5 on the tool sleeve 3, so that the second rotating shaft 30 will be rotated by the drive rod 25. The second rotating shaft 30 will synchronously rotate the second bevel gear 29. Since the second bevel gear 29 meshes with the first bevel gear 28 on the outer wall of the first rotating shaft 26, the plurality of stirring rods 27 on the outer wall of the first rotating shaft 26 can be rotated to stir the lubricating oil in the storage box 7, keeping the lubricating oil in a moving state at all times, and preventing the lubricating oil from precipitating after being stored for too long and affecting the lubrication effect.

[0040] Example 3, referring to Figures 1-9 , a tool sleeve flipping device for a chain belt type tool magazine. Compared with Example 2, on the basis of Example 2, sealing covers one 31 are fixedly connected to the outer walls on both sides of the frame body 1, and sealing covers two 32 are slidably connected to the opposite sides of the two sealing covers one 31. Two mounting plates 33 are fixedly connected to the outer wall of the top of the frame body 1, and a bidirectional threaded rod 35 is rotatably connected between the two mounting plates 33.

[0041] As a further solution in the present invention, a drive motor 37 is arranged at one end of the bidirectional threaded rod 35, and threaded sliders 34 are threadedly slidably connected to the outer walls on both sides of the bidirectional threaded rod 35. Fixed columns 36 are fixedly connected between the threaded sliders 34 and the corresponding sealing covers two 32. When the tool magazine is not in use, the drive motor 37 is started to rotate the connected bidirectional threaded rod 35 forward, enabling the two threaded sliders 34 on the outer wall of the bidirectional threaded rod 35 to approach each other. Since the threaded sliders 34 are connected to the corresponding sealing covers two 32 through the fixed columns 36, when the two threaded sliders 34 approach each other, the two sealing covers two 32 approach each other until the two sealing covers two 32 abut against each other. Thus, the frame body 1 of the tool magazine is sealed by the sealing covers one 31 and the sealing covers two 32, isolating the tools on each tool sleeve 3 in the frame body 1 from the external environment and preventing the tool sleeves 3 and the tools from being exposed to the external environment and contaminated with impurities.

[0042] Working principle: When the tool magazine is not in use, the drive motor 37 is started to make the bidirectional threaded rod 35 connected thereto rotate forward, enabling the two threaded sliders 34 on the outer wall of the bidirectional threaded rod 35 to approach each other. Since the threaded sliders 34 are connected to the corresponding second sealing covers 32 through the fixing columns 36, when the two threaded sliders 34 approach each other, the two second sealing covers 32 approach each other until the two second sealing covers 32 abut against each other. Thus, the frame 1 of the tool magazine is sealed by the first sealing cover 31 and the second sealing cover 32, isolating the tools on each tool sleeve 3 in the frame 1 from the external environment and preventing the tool sleeves 3 and the tools from being exposed to the external environment and contaminated with impurities.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
