[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3 The top of the workbench 1 is fixedly connected with a support block 14, and a thread rolling block 5 is arranged on the top of the support block 4 to facilitate supporting the thread rolling block 5. One side of the thread rolling block 5 is fixedly connected with a limit plate 17, and the limit plate 17 can limit the bolt to prevent it from deflecting when pushing the bolt. One side of the limit plate 17 is fixedly connected with a slide rail 8, and one end of the slide rail 8 is externally connected with a feeding mechanism, so as to facilitate the conveying of bolts. The top of the workbench 1 is fixedly connected with a support block 26, and the top of the support block 4 is fixedly connected with an electric push rod 12, and the output end of the electric push rod 12 is fixedly connected with a movable plate 13. When the electric push rod 12 works, it will drive the movable plate 13 to move, and the top of the support block 4 is fixedly connected with a limit plate 214, and the limit plate 214 can limit the movable plate 13 to prevent the movable plate 13 from deflecting when moving.

[0033] Reference Figure 1 and Figure 2The top of the workbench 1 is fixedly connected to a motor 9, and the output end of the motor 9 is fixedly connected to a disc 11. When the motor 9 is working, it will drive the disc 11 to rotate. The top of the disc 11 is fixedly connected to a limiting column 16. When the disc 11 rotates, it will drive the limiting column 16 to move at the same time. A limiting block 15 is set on the top of the disc 11. When the limiting column 16 moves, it will drive the limiting block 15 to move. The limiting block 15 is sleeved on the outer periphery of the limiting column 16. A moving rod 17 is fixedly connected to one side of the limiting block 15. When the limiting block 15 moves, it will drive the moving rod 17 to move at the same time. The top of the support block 4 is slidably connected to a thread rolling plate 18, and a refrigeration component is provided in the middle of the support block 2 6.

[0034] Reference Figure 3 The cooling assembly includes a second fan 28, which is fixedly connected to the middle of the support block 6. When the second fan 28 is working, it will blow air on the surface of the thread rolling plate 18, thereby performing air cooling to prevent the thread rolling plate 18 from rising in temperature due to long-term work, thereby affecting the quality of the bolts. A semiconductor refrigeration sheet 21 is fixedly connected to the top of the support block 6. When the refrigeration sheet 21 is working, it will cool down, thereby better cooling the thread rolling plate 18. The support block 6 is convenient for supporting the semiconductor refrigeration sheet 21. The top of the refrigeration plate 21 is fixedly connected with a heat dissipation fin 22, which facilitates the heat dissipation of the other side of the semiconductor refrigeration plate 21, so that the semiconductor refrigeration plate 22 can be better cooled. The top of the support block 2 6 is fixedly connected with a support block 3 19, and the middle of the support block 3 19 is fixedly connected with multiple fans 20. The support block 3 19 can support multiple fans 20 to facilitate the operation of fans 20. When fans 20 are working, they will blow air on the surface of the heat dissipation fin 22, so that the heat dissipation fin 22 can be better dissipated.

[0035] Reference Figure 4 and Figure 5 The two clamping blocks 27 are specifically provided with two, and the two clamping blocks 27 are both slidably connected to the interior of the connecting block 23. The two clamping blocks 27 can make the connecting block 23 and the thread rolling plate 18 more effectively fixed.

[0036] Reference Figure 1 and Figure 2 A placement box 3 is provided on one side of the workbench 1, which is convenient for storing the bolts after thread rolling. There are two limit plates 14, one of which is slidably connected to one side of the movable plate 13, and the other limit plate 14 is slidably connected to the other side of the movable plate 13. A plurality of support seats 2 are fixedly connected to the bottom of the workbench 1, and the plurality of support seats 2 can provide more stable support for the workbench 1. The top of the workbench 1 is fixedly connected to the limit frame 10, and the limit block 15 is slidably connected to one side of the limit frame 10. The limit frame 10 can limit the limit block 15 to prevent the limit block 15 from offsetting when moving.

[0037] Working principle: When the bolt is threaded, the bolt will slide from the middle of the slide rail 8 to one side of the movable plate 13. When the bolt slides to one side of the movable plate 13, the electric push rod 12 will work. When the electric push rod 12 works, it will move the movable plate 13 to facilitate the bolt to slide into the gap between the thread rolling block 5 and the limit plate 7. When the bolt slides into the gap between the thread rolling block 5 and the limit plate 7, the electric push rod 12 will drive the movable plate 13 to push the bolt to one side of the thread rolling plate 18. While pushing, the motor 9 will work. When the motor 9 is working, it will drive the disc 11 to rotate. When the disc 11 rotates, it will drive the limit column 16 to move at the same time. When the limit column 16 moves, it will drive the limit block 15 to move. When the limit block 15 moves, it will drive the moving rod 17 to move. When the moving rod 17 moves, it will drive the thread rolling plate 18 to move at the same time. When the thread rolling plate 18 moves, it will cooperate with the thread rolling fast 5 to facilitate thread rolling of the bolt.

[0038] When the thread rolling plate 18 is air-cooled, fan 28 will work. When fan 28 is working, it will blow air to the thread rolling plate 18. At the same time, the semiconductor refrigeration plate 21 will perform cooling work, thereby air-cooling the thread rolling plate 18. The top of the semiconductor refrigeration plate 21 is fixed with a heat dissipation fin 22. The heat dissipation fin 22 can dissipate heat to the other side of the semiconductor refrigeration plate 21, so that the semiconductor refrigeration plate 21 can be better cooled. When the heat dissipation fin 22 is dissipating heat, fan 1 20 will work. When fan 1 20 is working, it will blow air to the surface of the heat dissipation fin 22, thereby helping the heat dissipation fin 22 to dissipate heat more effectively.

[0039] When it is necessary to replace the corresponding thread rolling plate 18 according to the bolt, the two shift blocks 25 are moved toward each other by shifting. When the shift blocks 25 move, the spring 24 is squeezed. When the spring 24 is squeezed, the shift blocks 25 drive the clamping block 27 to move. When the clamping block 27 moves, it will disengage from the clamping slot 26. When the clamping block 27 disengages from the clamping slot 26, it is convenient to replace the corresponding thread rolling plate 18 according to the bolt.

[0040] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
