[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Such as Figure 1 、 2As shown in FIGS. 4 and 5, a protective structure of a cutting device includes a workbench main body 1; a cutting tool main body 11 is installed in the middle of the workbench main body 1; a bracket 12 is fixedly connected to the top of the workbench main body 1; a servo motor 13 is installed on the top of the bracket 12; a rotating shaft 14 is fixedly connected to the output end of the servo motor 13; the rotating shaft 14 is rotatably arranged in the middle of the bracket 12 and the workbench main body 1; two groups of nut grooves 19 are symmetrically arranged in the middle of the servo motor 13; a first sliding block 15 is threadedly connected to the rotating shaft 14; a second sliding block 16 is threadedly connected to the middle of the rotating shaft 14; the first sliding block 15 and the second sliding block 16 are slidably arranged on the inner wall of the servo motor 13; a protective cover 17 is fixedly connected to the end of the first sliding block 15; the protective cover 17 is arranged on the top of the cutting tool main body 11; a container 18 is fixedly connected to the end of the second sliding block 16; during operation, the operator needs to install the workbench main body 1 in the working area, and then place the plate to be cut in the middle of the workbench main body 1. After that, the operator can power on the workbench main body 1, so that the cutting tool main body 11 rotates and cuts the plate. By providing a bracket 12 on the top of the workbench main body 1, during the operation of the cutting tool main body 11, the operator can turn on the switch of the servo motor 13, so that the output end of the servo motor 13 drives the rotating shaft 14 to rotate. With the two groups of symmetrically arranged nut grooves 19 in the middle of the rotating shaft 14, the first sliding block 15 and the second sliding block 16 will slide up and down in the middle of the bracket 12 under force, and the position of the protective cover 17 will gradually approach the top of the cutting tool main body 11. After adjusting to the appropriate position, the protective cover 17 will block the high-temperature residues generated by cutting spatter. At the same time, the operator can add an appropriate amount of anti-rust coolant into the container 18 in advance. After the container 18 moves upward, the bottom position of the cutting tool main body 11 will gradually contact the coolant in the container 18. This step, combined with the container 18 and the protective cover 17 that can move up and down in the middle of the cutting tool main body 11, uses the protective cover 17 to reduce the problem of some high-temperature residues splashing outside, improving the protection of the operator when operating the cutting tool main body 11. Combined with the anti-rust coolant provided in the container 18, after contacting the middle of the cutting tool main body 11, it can cool down the surface temperature of the cutting tool main body 11, and at the same time reduce the phenomenon of more rust spots appearing on the middle part of the cutting tool main body 11 after long-term use.

[0025] As Figure 2 , 4As shown in FIGS. 4 and 5, two groups of first springs 2 are fixedly connected to the inner wall of the bottom of the container 18; two groups of limit members 21 are fixedly connected to the side wall of the container 18; a slide plate 22 is slidably connected to the middle of the limit member 21, and the slide plate 22 is fixedly connected to the top of the first spring 2; a push plate 23 is fixedly connected to the top of the slide plate 22; the middle of the push plate 23 is inclined; two groups of pull ropes 24 are fixedly connected to the top of the slide plate 22, and the other ends of the pull ropes 24 are fixedly connected to the middle of the bracket 12; during operation, by arranging two groups of limit members 21 on the inner wall of the container 18, when the container 18 gradually approaches the cutting tool main body 11, the fixed end of the pull rope 24 at the middle of the bracket 12 will pull the slide plate 22 to move upward, and during the pulling process, the overall length of the first spring 2 is stretched. With the inclined push plate 23 arranged on the top of the slide plate 22, a part of the coolant inside the container 18 can be transferred to the middle of the cutting tool main body 11. Subsequently, when the container 18 moves away from the cutting tool main body 11, the position can be reset by means of the elastic force generated by the first spring 2. This step, combined with the inclined push plate 23 to transfer part of the coolant to the middle of the cutting tool main body 11, can increase the area of the surface of the cutting tool main body 11 cooled by the coolant, and at the same time can increase the rust-proof area in the middle of the cutting tool main body 11, further increasing the service life of the cutting tool main body 11 during use and reducing the problem that a large number of rust spots appear in the middle of the cutting tool main body 11, resulting in the need for frequent replacement by the staff.

[0026] As Figure 2 and 3 shown, a support rod 3 is fixedly connected to the end of the servo motor 13; a second spring 31 is fixedly connected to the end of the support rod 3; a counterweight ball 32 is fixedly connected to the end of the second spring 31; the counterweight ball 32 is arranged at the top of the protective cover 17; during operation, by arranging a support rod 3 in the middle of the bracket 12, when the protective cover 17 moves upward, its top will gradually approach the middle of the counterweight ball 32 until the top of the protective cover 17 contacts the middle of the counterweight ball 32, and the middle of the second spring 31 is deformed during the contact and impact process. This step, combined with the counterweight ball 32 arranged at the top of the protective cover 17, can clean part of the impurities attached and caked on the inner wall of the protective cover 17 by using the force generated during the impact with the protective cover 17, improving the cleanliness of the inner wall of the protective cover 17 and reducing the problem that a thick layer of impurities accumulates on the inner wall of the protective cover 17, affecting the rotating cutting tool main body 11.

[0027] As Figure 4As shown, two sets of guide sleeves 4 are fixedly connected to the top of the container 18; a plurality of rotating beads 41 are rotatably connected to the inner wall of the guide sleeve 4; the rotating beads 41 are arranged in a circumferential array on the inner wall of the guide sleeve 4; the pull rope 24 is slidably arranged on the inner wall of the guide sleeve 4; during operation, by providing the guide sleeve 4 at the top of the container 18, when the pull rope 24 is pulled to move on the inner wall of the container 18, the working position of the pull rope 24 can be limited in cooperation with the guide sleeve 4. At the same time, the pull rope 24 will sequentially contact the rotating beads 41 during the movement process. This step, in cooperation with the guide sleeve 4, can improve the stability of the pull rope 24 during operation, reduce the problem of entanglement between the two pull ropes 24, and at the same time, the rotating beads 41 can reduce the wear of the pull rope 24 during the sliding process.

[0028] As Figure 4 shown, a chute 5 is provided in the middle of the guide sleeve 4; the middle of the chute 5 is inclined; a scraper 51 is fixedly connected to the end of the guide sleeve 4; the inner wall of the scraper 51 is in contact with the middle of the pull rope 24; during operation, by providing the scraper 51 at the end of the guide sleeve 4, when the pull rope 24 moves, the scraper 51 will scrape off part of the coolant attached to the middle of the pull rope 24, and then transfer it to the inside of the container 18 for collection again in cooperation with the inclined chute 5. This step, in cooperation with the scraper 51, can improve the cleanliness of the middle of the pull rope 24 and reduce the problem that the coolant attached to the middle of the pull rope 24 drips onto the ground, resulting in material waste and pollution of the working environment.

[0029] As Figure 3 shown, a plurality of counterweight bars 6 are fixedly connected to the middle of the counterweight ball 32; the counterweight bars 6 are arranged in a circumferential array in the middle of the counterweight ball 32; during operation, by providing a plurality of counterweight bars 6 in the middle of the counterweight ball 32, when the top of the protective cover 17 is close to the counterweight ball 32, the rubber pad 7 will contact the top of the protective cover 17 first. This step, in cooperation with a plurality of second springs 31, can increase the contact area between the protective cover 17 and the counterweight ball 32, thereby increasing the force generated when hitting the middle of the protective cover 17.

[0030] As Figure 5 shown, two rubber pads 7 are fixedly connected to the top of the sliding plate 22; the inner wall of the rubber pad 7 is in contact with the end of the sliding plate 22; during operation, by providing the rubber pad 7 at the top of the sliding plate 22, the rubber pad 7 made of a soft material will protect the connection between the end of the pull rope 24 and the sliding plate 22. This step, in cooperation with the rubber pad 7 made of a soft material, can reduce the problem of connection breakage between the end of the pull rope 24 and the sliding plate 22 after the pull rope 24 is frequently used.

[0031] Working principle: by installing the workbench body 1 in the working area, and then placing the plate to be cut in the middle of the workbench body 1, the staff can power on the workbench body 1 to rotate the cutter body 11 and cut the plate. By setting a bracket 12 on the top of the workbench body 1, the staff can turn on the servo motor 13 when the cutter body 11 is working, so that the output end of the servo motor 13 will drive the rotating shaft 14 to rotate, and cooperate with the two groups of symmetrically arranged nut grooves 19 in the middle of the rotating shaft 14, so that the first sliding block 15 and the second sliding block 16 will slide up and down in the middle of the bracket 12 after being subjected to force, and the protective cover 17 is positioned The protective cover 17 will gradually approach the top of the cutter body 11. After adjusting to a suitable position, the protective cover 17 will block the high-temperature residues generated by the cutting splashes. At the same time, the staff can add a proper amount of anti-rust coolant to the container 18 in advance. After the container 18 moves upward, the bottom position of the cutter body 11 will gradually contact the coolant inside the container 18. By setting two sets of limiters 21 on the inner wall of the container 18, when the container 18 gradually approaches the position of the cutter body 11, the end of the pull rope 24 fixed in the middle of the bracket 12 will pull the slide plate 22 upward, and in the process of pulling, the overall length of the first spring 2 is lengthened, and the tilting device set on the top of the slide plate 22 is used to adjust the height of the slide plate 22. The inclined push plate 23 can transfer part of the coolant in the container 18 to the middle of the cutter body 11. Then, when the container 18 is away from the cutter body 11, it can be reset by the elastic force generated by the first spring 2. By arranging a support rod 3 in the middle of the bracket 12, the top of the protective cover 17 will gradually approach the middle of the counterweight ball 32 when it moves upward, until the top of the protective cover 17 contacts the middle of the counterweight ball 32, and squeezes the middle of the second spring 31 to deform during the contact and collision process. By arranging a guide sleeve 4 at the top of the container 18, when the pull rope 24 is pulled to move on the inner wall of the container 18, the guide sleeve 4 can cooperate with the pull rope 24 to move the working position of the pull rope 24. It is limited that the pull rope 24 will contact the rotating bead 41 in sequence during the movement. By arranging a scraper 51 at the end of the guide sleeve 4, the scraper 51 will scrape off part of the coolant attached to the middle part of the pull rope 24 when the pull rope 24 moves, and then transfer it to the inside of the container 18 for collection again in conjunction with the inclined slide 5. By arranging a plurality of counterweight bars 6 in the middle of the counterweight ball 32, the rubber pad 7 will contact the top of the protective cover 17 before the top of the protective cover 17 when the top is close to the counterweight ball 32. By arranging a rubber pad 7 on the top of the slide plate 22, the rubber pad 7 made of soft material will protect the connection between the end of the pull rope 24 and the slide plate 22.
