The side of the slide plate close to the moving rod 20 is slidingly connected through a sliding plate, and the side of the slide plate away from the moving rod 20 is rotationally connected to the clamp block through a rotating shaft. A power source is provided in the middle of the side of the slide plate away from the moving rod 20. The power source is fixedly connected to the connecting plate, and one side of the connecting plate is rotationally connected to the connecting rod through a rotating shaft.

[0021] First, the cylinder 16 is used to push the first toothed plates 12 on both sides, so that the first toothed plates 12 can drive the clamping plates 13 on both sides to fix the front beam through the setting of the first gear 11. When the clamping plates 13 fix the front beam, the sleeve rod 14 and the spring 15 on one side of the clamping plates 13 can be fixed according to the different shapes and sizes of the front beam. When the first toothed plate 12 moves, the top plate 17 can move synchronously, so that the second toothed plate 19 on the top of the plate 17 moves synchronously. When the second toothed plate 19 moves to the moving position, it is resisted. The tension spring 18 is used to ensure that there is no squeezing between the plate 17 and the second toothed plate 19. When the second toothed plate 19 moves, the meshing second gear 28 rotates, and the moving rod 20 on the top of the second gear 28 rotates according to the motion trajectory of the second gear 28, so that the auxiliary clamping assembly 21 slidably connected on one side of the moving rod 20 can perform auxiliary clamping on the front beam again, so as to avoid instability of the front beam when cutting the middle part of the front beam.

[0022] The auxiliary clamping assembly 21 is mainly composed of a clamping block, a connecting rod, a connecting plate, a rotating shaft, a slide plate, etc. The front beam can be clamped and fixed by the clamping block, the connecting rod, the connecting plate, the rotating shaft, and the slide plate. The auxiliary clamping assembly 21 can also clamp different front beams through these settings.

[0023] like Figure 2 , Figure 5 As shown, a protective plate 2 is provided on one side of the table top 1, an inner plate 3 is provided inside the protective plate 2, a double-headed motor 5 is provided inside the inner plate 3, the output shaft end of the double-headed motor 5 is rotatably connected to a first bevel gear 6, the first bevel gear 6 is meshed with a second bevel gear 7, a connecting block 8 is provided on one side of the second bevel gear 7, the connecting block 8 is threadedly connected to a screw rod 9, and a fixing block 10 is provided on the outer ring of the screw rod 9.

[0024] The above scheme is adopted: a protective plate 2 is arranged on one side of the table 1. When cutting, the protective plate 2 can play an effective protective effect to prevent various dangerous factors generated during the cutting process from causing harm to the surrounding environment and operators. An inner plate 3 is arranged inside the protective plate 2. The existence of the inner plate 3 provides key support for the lifting and lowering of the protective plate 2. Through the setting of the inner plate 3, the protective plate 2 can be driven to perform lifting operations, so that the height of the protective plate 2 can be adjusted according to actual needs to better adapt to different cutting conditions. A double-headed motor 5 is arranged inside the inner plate 3. The setting of the double-headed motor 5 can drive the first bevel gears 6 on both sides. When the first bevel gear 6 rotates, it will mesh with the second bevel gear 7, thereby driving the second bevel gear 7 to rotate. When the second bevel gear 7 rotates, it will drive the fixedly connected screw rod 9. In this way, the screw rod 9 can operate upward inside the inner plate 3. In this process, the connecting block 8 on one side of the screw rod 9 will drive the protective plate 2 to rise upward. When performing cutting operations, the setting of the protective plate 2 is very important. It can play a good protective effect, effectively prevent the debris generated during the cutting process from splashing, and protect the operator and the surrounding environment. At the same time, it can also improve the safety and reliability of the cutting operation to a certain extent.

[0025] like Figure 5 , Figure 6 As shown, the bottom of the inner plate 3 is fixedly connected to the base 4, the base 4 is fixedly connected to the stabilizing legs at the bottom of the table top 1, the side of the connecting block 8 away from the screw rod 9 is fixedly connected to the inside of the protective plate 2, the fixing block 10 is fixedly connected to the inside of the inner plate 3, the side of the first tooth plate 12 away from the first gear 11 is fixedly connected to the cylinder 16, and the cylinder 16 is fixedly connected to the table top 1.

[0026] The above scheme is adopted: the bottom of the inner plate 3 is fixedly connected with the base 4, the base 4 can provide strong support for the inner plate 3, play a stable fixing role, and ensure that the inner plate 3 can maintain a stable state under various working conditions. The side of the connecting block 8 away from the screw rod 9 is fixedly connected to the inside of the protective plate 2. When the subsequent connecting block 8 moves upward, this design can synchronously drive the protective plate 2 to move upward, ensuring that the lifting and lowering action of the protective plate 2 is accurate. The fixing block 10 is fixedly connected to the inside of the inner plate 3, so that the screw rod 9 can move upward through the setting of the fixing block 10. The fixing block 10 is a screw rod. The movement of the rod 9 provides stable support and guidance, ensuring the smoothness and accuracy of the movement of the screw rod 9. The first tooth plate 12 is fixedly connected to the side away from the first gear 11 with a cylinder 16. The cylinder 16 is fixedly connected to the table 1 on the side away from the first tooth plate 12. The cylinder 16 provides a strong driving force for the first tooth plate 12 in the entire device, so that the first tooth plate 12 can be pushed by the setting of the cylinder 16. In actual operation, the movement of the first tooth plate 12 can achieve a fixed clamping effect on the front beam, ensuring that the front beam remains stable during the cutting process, thereby improving the cutting accuracy and quality.

[0027] like Figure 3 , Figure 8 As shown, a slide groove is provided on the top of the positioning plate 23, a sliding block is fixedly connected to the side of the positioning rod 24 close to the positioning plate 23, a positioning spacing rod is provided on the side of the positioning plate 23 close to the positioning rod 24, a rod sleeve is fixedly connected to the side of the positioning rod 24 close to the positioning plate 23, a fixing rod 25 is fixedly connected to the top of the base 4, the internal rotation of the fixing rod 25 is connected to a rotating rod body 26, and the outer ring of the rotating rod body 26 is connected to a support block 27.

[0028] The above scheme is adopted: a sliding groove is provided on the top of the positioning plate 23, so that the sliding block of the positioning rod 24 close to the side of the positioning plate 23 can slide on the positioning plate 23 more smoothly. Through this sliding method, different positioning values ​​can be conveniently adjusted to meet various specific positioning needs. At the same time, a positioning spacing rod is also provided on the side of the positioning plate 23 close to the positioning rod 24. This positioning spacing rod has an important role. It can allow the rod sleeve on the positioning rod 24 to cover it. In this way, during use, the positioning rod 24 can be effectively prevented from being positioned offset, thereby playing a better role in positioning accuracy. A fixing rod 25 is fixedly connected to the top of the base 4, and the internal rotation of the fixing rod 25 is connected to the rotating rod body 26, and the outer ring of the rotating rod body 26 is provided with a support block 27. This design enables the overall fixing rod 25 and support block 27 device to provide an auxiliary support effect on the cutting front beam. With this auxiliary support, it will be more convenient to position and cut the front beam, and the stability and accuracy of the front beam during the cutting process can be better ensured.

[0029] The working principle and use process of the present invention: First, the cylinder 16 is used to push the first toothed plates 12 on both sides. In this process, the first toothed plates 12 can drive the clamping plates 13 on both sides with the help of the first gear 11, so as to firmly fix the front beam. When the clamping plates 13 fix the front beam, the sleeve rod 14 and the spring 15 on one side of the clamping plates 13 can be adaptively adjusted according to the different shapes and sizes of the front beam to ensure the firmness and stability of the fixation. When the first toothed plate 12 moves, the plate 17 on its top can move synchronously. In this way, the second toothed plate 19 on the top of the plate 17 will also be displaced synchronously. When the second toothed plate 19 moves to a specific position, it will be resisted by the corresponding components. Through the setting of the tension spring 18, it can be ensured that the plate 17 and the second toothed plate 19 will not be excessively squeezed, thereby maintaining the stability of the device. When the second toothed plate 19 moves, the second gear 28 meshing with it will rotate, and the second gear 28 will push The moving rod 20 at the top will rotate according to the movement trajectory of the second gear 28, so that the auxiliary clamping assembly 21 slidably connected on one side of the moving rod 20 can assist in clamping the front beam again. This operation can effectively avoid the instability of the front beam due to lack of sufficient support when cutting the middle part of the front beam. After the front beam is fixed and clamped twice, the positioning rod 24 can be adjusted and positioned according to the value on the positioning plate 23 by sliding the positioning rod 24. Such a design can facilitate accurate positioning and cutting of the front beam, greatly improving the cutting accuracy and quality. In addition, the fixed rod 25 on the top of the base 4 and the support block 27 on the top of the fixed rod 25 can provide an auxiliary support for the clamped and fixed front beam, and the protective plate 2 on one side of the table 1 can play a good protective role during cutting, effectively preventing various dangerous factors generated during the cutting process from causing harm to the surrounding environment and operators.
