[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Please see Figure 1-4This utility model provides a technical solution: including a base 1, an equipment rack 2 fixed on the upper end of the base 1, a three-axis track 3 installed on the front side of the equipment rack 2, a laser cutting head 4 installed on the three-axis track 3, a pair of fixed frames 5 fixed on the upper end of the base 1, a rotating plate 6 rotatably connected inside the fixed frame 5, a square hole 64 adapted to the size of the square tube opened at the center of the rotating plate 6, an anti-slip pad fixed inside the square hole 64, a protective frame 7 fixed on the upper end of the base 1 and located between the fixed frames 5, and a drive component for driving the rotating plate 6 to rotate inside the protective frame 7.

[0016] The drive assembly includes an annular toothed plate 75 and a stepper motor 72. A linkage shaft 71 is rotatably connected inside and through the protective frame 7. Transmission gears 74 are fixed at both ends of the linkage shaft 71. The annular toothed plate 75 is fixed on the outside of the rotating plate 6 and meshes with the transmission gears 74. The stepper motor 72 is fixed inside the base 1. A transmission bevel gear 73 that meshes with each other is fixed at the middle position of the linkage shaft 71 and the output end of the stepper motor 72.

[0017] The rotating plate 6 consists of an outer plate 61 and an inner plate 62. The outer plate 61 is rotatably connected to and passes through the fixed frame 5. An insertion slot 63 is provided at the center of the outer plate 61. The inner plate 62 is inserted into the insertion slot 63. A square hole 64 passes through the center of the inner plate 62. The inner plate 62 and the insertion slot 63 are a matching T-shaped structure. Positioning rods 66 are fixed at equal intervals on the inner side of the inner plate 62. Positioning holes 65 are provided on the inner side of the outer plate 61 at positions corresponding to the positioning rods 66. A pair of slots 81 are provided on the outer side of the inner plate 62. A baffle 8 is installed on the outer side of the outer plate 61 at positions corresponding to the slots 81. A telescopic groove is provided on the outer side of the outer plate 61 at positions corresponding to the baffle 8. A telescopic rod 82 is slidably connected in the telescopic groove. A telescopic spring 83 is fixed between the inner side of the telescopic rod 82 and the inner sidewall of the telescopic groove. The outer side of the telescopic rod 82 is rotatably connected to the baffle 8.

[0018] Working principle: First, connect the entire device to an external power source. Then, insert the square tube between the rotating plates 6. When the square tube passes through the square hole 64 that matches its size, it can ensure that the square tube can rotate synchronously with the rotating plate 6. Based on this, the stepper motor 72 and the transmission bevel gear 73 drive the linkage shaft 71 and the transmission gear 74 to rotate. Then, the ring toothed plate 75 drives the rotating plate 6 to rotate, ultimately achieving the purpose of rotating and cutting the square tube. When cutting square tubes of different sizes, simply replace the inner plate 62 with the one that matches the size of the square hole 64. During the replacement process, insert the inner plate 62 into the outer plate 61 and insert the positioning rod 66 into the positioning hole 65. This ensures that the rotation of the outer plate 61 can drive the inner plate 62 to rotate synchronously. After installation, rotate the baffle 8 so that the baffle 8 is aligned with the slot 81. Under the pull of the telescopic spring 83, the baffle 8 can be inserted into the slot 81 to achieve the purpose of locking and fixing.
