Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 This utility model provides an embodiment of a pneumatic vibrating cutter, including a locking ring 1. The locking ring 1 has a tool-changing mechanism inside for switching between different cutter bodies. The tool-changing mechanism also has a locking component inside for locking the switched cutter body. The tool-changing mechanism includes a rotating shaft 10, which is rotatably connected to the inner wall of the locking ring 1. A limit ring 11 is fixedly connected to the outer wall of the rotating shaft 10. A support shaft 12 is slidably connected inside the limit ring 11. A corrugated ring 8 is rotatably connected to the outer wall of the rotating shaft 10. A second motor 9 is fixedly connected inside the corrugated ring 8. The output end of the second motor 9 is fixedly connected to the side wall of the rotating shaft 10. One end of a first spring 15 is fixedly connected to the side wall of the limit ring 11. The other end of the first spring 15 is fixedly connected to a locking component. The locking component is fixedly connected to one end of the outer wall of the support shaft 12. A locking groove 14 is provided inside the locking ring 1. A cutter body is installed on the side wall of the support shaft 12.

[0023] The locking assembly includes an outer shell 16, which is fixedly connected to one end of the outer wall of the support shaft 12. The other end of the outer shell 16 is fixedly connected to the outer shell 16. A limiting plate 17 is fixedly connected inside the outer shell 16. A limiting groove 18 is formed on the outer wall of the limiting plate 17. A motor 19 is fixedly connected inside the limiting plate 17. A gear 20 is fixedly connected to the output end of the motor 19. A gear 21 is rotatably connected to the outer wall of the limiting plate 17. Gear 20 and gear 21 mesh with each other.

[0024] The outer wall of the outer shell 16 has a slot 32, and one end of the expansion rod 23 passes through the slot 32.

[0025] refer to Figure 2 , Figure 3 and Figure 4Specifically, in the tool changing mechanism, when a tool needs to be replaced, motor 29 is started. Motor 29 drives the limit ring 11 to rotate, which in turn drives the support shaft 12 to rotate. One end of the support shaft 12 gradually moves down along the corrugated pipe pattern and stretches the spring 15, causing the locking component to enter the locking groove 14. Then, motor 19 drives gear 10 to rotate, and gear 10 meshes with gear 21, causing gear 21 to rotate. The arc-shaped groove 22 inside gear 21 cooperates with the expansion rod 23. As gear 21 rotates, the expansion rod 23 moves outward under the action of the arc-shaped groove 22 and the limit groove 18, so that the expansion rod 23 is locked in the locking groove 14 of the locking ring 1, completing the locking of the tool. After the replacement is completed, motor 19 is operated in reverse to disengage the locking component from the locking groove 14. The support rod rotates and rises under the action of spring 15 and rotating shaft 10. Then, the next tool continues to repeat the above process to complete the replacement of multiple tools. During the cutting process, compressed air enters the cylinder 7 and pushes the bellows ring 8 to slide inside the cylinder 7. The bellows ring 8 drives the connected cutter to move up and down. At the same time, the motor 9 can drive the cutter to rotate at a certain angle through the rotating shaft 10 according to the different materials being cut, so that the cutter can cut at the optimal angle.

[0026] In addition, this utility model also provides a cutting device, including a base 13. An auxiliary mechanism is provided on the upper part of the base 13, which is used to build the basic working environment of the cutting device. A cylinder 7 is provided on the outside of the auxiliary mechanism, and a protection mechanism is provided inside the cylinder 7, which is used to forcibly cut off the power source when the device is overloaded. The auxiliary mechanism includes a limiting rod 2, which is fixedly connected to the inner wall of the base 13. An adjusting block 3 is slidably connected to the outer wall of the limiting rod 2. A threaded rod 4 is threadedly connected inside the adjusting block 3. The two ends of the threaded rod 4 pass through the adjusting block 3 and are rotatably connected to the inner wall of the base 13. An air compressor 6 is fixedly connected to the outer wall of the base 13.

[0027] The protective mechanism includes an adjusting rod 24, one end of which is slidably connected to the outer wall of the cylinder 7, and the other end of which passes through the cylinder 7 and is fixedly connected to an adjusting knob 25. A second spring 26 surrounds the outer wall of the adjusting rod 24, and one end of a first protective rod 27 is fixedly connected to the outer wall of the second spring 26. The other end of the first protective rod 27 is rotatably connected to one end of a second protective rod 28, and the other end of the second protective rod 28 is fixedly connected to a sealing cover 29. The second protective rod 28 is rotatably connected inside the cylinder 7.

[0028] The output end of the air compressor 6 is connected to one end of the inlet pipe 30 and one end of the outlet pipe 31, respectively. The other end of the inlet pipe 30 and the other end of the outlet pipe 31 are connected to the outer wall of the cylinder 7.

[0029] The base 13 has a motor 5 fixedly connected inside, and the output end of the motor 5 is fixedly connected to one end of the threaded rod 4.

[0030] refer toFigure 1 Specifically, when the equipment is working, the air compressor 6 first provides compressed air, which enters the cylinder 7 through the air inlet pipe 30. In terms of the auxiliary mechanism, the motor 5 drives the threaded rod 4 to rotate. Since the adjusting block 3 is threadedly connected to the threaded rod 4 and can only slide left and right along the limit rod 2 under the restriction of the limit rod 2, the position of the adjusting block 3 on the base 13 can be adjusted. In this way, the horizontal position of the entire tool changing mechanism and the tool can be adjusted according to the cutting requirements.

[0031] When the equipment is overloaded, the protection mechanism kicks in. The excessive force generated by the overload will compress the bellows 8 and spring 26. The compression of spring 26 will cause the protective rod 27 to rise and the protective rod 28 to rotate. One end of the protective rod 28 rises, while the other end drives the sealing cover 29 to move down, thereby cutting off the air intake passage of cylinder 7, forcibly cutting off the power source, preventing the equipment from being damaged due to overload, protecting the safety of the equipment, extending the service life of the equipment, and ensuring the stable and reliable operation of the cutting work.

[0032] Working principle: When the equipment is working, the air compressor 6 first provides compressed air, which enters the cylinder 7 through the air inlet pipe 30. In terms of auxiliary mechanism, the motor 5 drives the threaded rod 4 to rotate. Since the adjusting block 3 is threadedly connected to the threaded rod 4 and can only slide left and right along the limit rod 2 under the restriction of the limit rod 2, the position of the adjusting block 3 on the base 13 can be adjusted. Then, the horizontal position of the entire tool changing mechanism and the tool can be adjusted according to the cutting requirements.

[0033] In the tool changing mechanism, when a tool needs to be changed, motor 29 is started. Motor 29 drives the limit ring 11 to rotate, which in turn drives the support shaft 12 to rotate. One end of the support shaft 12 gradually moves down along the corrugated pipe pattern and stretches the spring 15, causing the locking component to enter the locking groove 14. Then, motor 19 drives gear 10 to rotate, and gear 10 meshes with gear 21, causing gear 21 to rotate. The arc groove 22 inside gear 21 cooperates with the expansion rod 23. As gear 21 rotates, the expansion rod 23 moves outward under the action of the arc groove 22 and the limit groove 18, so that the expansion rod 23 is locked in the locking groove 14 of the locking ring 1, completing the locking of the tool. After the replacement is completed, motor 19 is operated in reverse to disengage the locking component from the locking groove 14. The support rod rotates and rises under the action of spring 15 and rotating shaft 10. Then, the next tool continues to repeat the above process to complete the replacement of multiple tools. During the cutting process, compressed air enters the cylinder 7 and pushes the bellows ring 8 to slide inside the cylinder 7. The bellows ring 8 drives the connected cutter to move up and down. At the same time, the motor 9 can drive the cutter to rotate at a certain angle through the rotating shaft 10 according to the different materials being cut, so that the cutter can cut at the optimal angle.

[0034] When the equipment is overloaded, the protection mechanism kicks in. The excessive force generated by the overload will compress the bellows 8 and spring 26. The compression of spring 26 will cause the protective rod 27 to rise and the protective rod 28 to rotate. One end of the protective rod 28 rises, while the other end drives the sealing cover 29 to move down, thereby cutting off the air intake passage of cylinder 7, forcibly cutting off the power source, preventing the equipment from being damaged due to overload, protecting the safety of the equipment, extending the service life of the equipment, and ensuring the stable and reliable operation of the cutting work.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
