[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3, the utility model provides an embodiment: a CNC spring machine with a protective structure, including a workbench 1, a storage box 2 is fixedly connected to the upper surface of the workbench 1, a protective plate 3 is fixedly connected to the side wall of the storage box 2, a cylinder 4 is fixedly connected to the inside of the protective plate 3, a driving column 5 is fixedly connected to the output end of the cylinder 4, a hollow ring 6 is fixedly connected to the outer wall of the driving column 5, a limiting column 9 is fixedly connected to the outer wall of the driving column 5, a support block 8 is fixedly connected to the outer wall of the hollow ring 6, a connecting rod 10 is rotatably connected to the inside of the support block 8, a supporting plate 12 is rotatably connected to one side of the connecting rod 10, a connecting rod 2 11 is rotatably connected to the inside of the supporting plate 12, a hollow column 7 is slidably connected to the outer wall of the driving column 5, the limiting column 9 is slidably connected to the inside of the hollow column 7, the connecting rod 2 11 is rotatably connected to the outer wall of the hollow column 7, the connecting rod 10 is rotatably connected to the inside of the connecting rod 2 11, and a supporting component is arranged on one side of the protective plate 3;

[0024] Specifically, the cylinder 4 pulls the driving column 5 to move through the output end. This movement process is not isolated, and it will trigger a series of chain reactions. Then, the movement of the driving column 5 will drive the hollow ring 6 to move accordingly. The hollow ring 6 is to undertake the subsequent force transmission. In this process, the support block 8 will also be driven and move with the hollow ring 6. Then, the movement of the support block 8 will further drive the connecting rod 10 to rotate inside the connecting rod 2 11. This is a key step, because the rotation of the connecting rod 10 will transfer the force to the support plate 12. In this process, the limit column 9 will slide inside the hollow column 7. This design ensures that the spring can maintain a stable position during the processing. As the connecting rod 10 rotates, the support plate 12 will shrink toward the center, so that the spring can maintain a good shape and tension during the processing. After the support plate 12 has shrunk, the spring can be placed in the device. Next, start the cylinder 4 to drive the support plate 12 to extend outward. This step is to maintain the tension of the spring during the processing.

[0025] Reference Figure 1 and Figure 4 The support assembly includes a fixed plate 13, a fixed block 14 is fixedly connected to the side wall of the fixed plate 13, the fixed plate 13 is fixedly connected to the side wall of the protective plate 3, the side wall of the fixed block 14 is rotatably connected to a rotating plate 15, the side wall of the rotating plate 15 is fixedly connected to an electric push rod 16, and the output end of the electric push rod 16 is rotatably connected to a baffle 17;

[0026] Specifically, by operating the electric push rod 16, its output end drives the baffle 17 to rotate. The electric push rod 16 is an important part of the transmission system and provides power for the rotation of the baffle 17. Then, the rotation of the electric push rod 16 drives the rotating plate 15 to rotate on the outer wall of the fixed block 14. The fixed block 14 plays a role of fixing and supporting, ensuring that the rotating plate 15 remains stable during the rotation process, which makes the entire transmission system more solid and reliable, and helps to prevent accidental damage. The baffle 17 is made of acrylic material, which has high transparency, so that the internal situation can be observed during processing, and it has high impact resistance and is not easy to break.

[0027] Reference Figure 1 and Figure 4 The side wall of the protective plate 3 is fixedly connected with a fixing block 2 18, the inside of the fixing block 2 18 is fixedly connected with a fixing column 20, the outer wall of the fixing column 20 is rotatably connected with a connecting block 19, the connecting block 19 is fixedly connected to the side wall of the baffle 17, the baffle 17 is fitted with the protective plate 3, the upper surface of the baffle 17 is fixedly connected with a stopper 21, and the upper surface of the workbench 1 is fixedly connected with a support column 22;

[0028] Specifically, the protective device mainly includes a baffle 17, a connecting block 19, a fixed column 20 and a block 21. The baffle 17 is made of acrylic material and has good impact resistance. During the spring processing, the baffle 17 intercepts and blocks the splashing material. The connecting block 19 is connected to the baffle 17 and can rotate freely on the outer wall of the fixed column 20. When the baffle 17 rotates to contact the protective plate 3, the block 21 will play a blocking role to prevent the baffle 17 from over-closing. In this way, during the spring processing, even if the material splashes or the spring breaks out, it can be intercepted and controlled in time, reducing the risk of injury to the staff. In addition, this protective device also fully considers the convenience of operation. After completing the closing of the baffle 17, the staff can easily perform subsequent spring processing operations. When the protective device is not needed, the baffle 17 can be quickly opened to ensure the smooth progress of the production process.

[0029] Working principle: when the staff needs to fix the spring during processing, they first pull the driving column 5 through the output end of the cylinder 4 to move it, and then drive the hollow ring 6 to move, and the movement of the hollow ring 6 will drive the support block 8 to move together, and the movement of the support block 8 will drive the connecting rod 1 10 to rotate inside the connecting rod 2 11, and at the same time drive the limit column 9 to slide inside the hollow column 7, and the rotation of the connecting rod 10 will drive the support plate 12 to shrink toward the center, and also drive the connecting rod 2 11 to rotate. After the support plate 12 has shrunk, the spring can be put on the side wall of the support plate 12, and then start the cylinder 4 to drive the support plate 12 to extend outward, so that The spring can be supported internally so that it maintains its shape and tension during processing. When the staff needs to close the baffle 17 during spring processing, the baffle 17 is first driven to rotate by the output end of the electric push rod 16, and then the electric push rod 16 drives the rotating plate 15 to rotate on the outer wall of the fixed block 14. The rotation of the baffle 17 will drive the connecting block 19 to rotate on the outer wall of the fixed column 20. When the baffle 17 contacts the protective plate 3, the block 21 will block the baffle 17, so as to prevent the baffle 17 from being damaged due to excessive closing. At this time, the baffle 17 is closed, so as to prevent material splashing or spring fragments from flying out during spring processing, causing harm to the staff.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
