[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 - Figure 3 , an embodiment provided by the present utility model: A bolt heat treatment device for automobiles includes a heating box 1. A fixed frame 2 is fixedly connected to the top of the heating box 1. A motor 3 is fixedly connected to the front side of the fixed frame 2. The output end of the motor 3 is fixedly connected to a first gear 4. Four connecting frames 5 are fixedly connected to the top edge of the first gear 4. A gear ring 6 is fixedly connected between the bottoms of the four connecting frames 5. The inner top wall of the heating box 1 is rotatably connected to a rotating rod 7. The top end of the rotating rod 7 is fixedly connected to a second gear 8. The second gear 8 meshes with the first gear 4, and the second gear 8 meshes with the gear ring 6. A connecting rod 9 is slidably connected to the bottom of the rotating rod 7. Three placement frames 10 are fixedly connected to the outside of the connecting rod 9. A fixing component is installed on the outside of the lower side of the rotating rod 7. A plurality of heating rods 11 are fixedly connected inside the heating box 1. The bottom of the first gear 4 is rotatably connected to the top of the heating box 1. The bottom of the second gear 8 is rotatably connected to the top of the heating box 1. The bottom of the gear ring 6 is rotatably connected to the top of the heating box 1.

[0032] Specifically, the heating box 1 is a container for heat-treating nuts. It has a door on its front side to facilitate the loading and unloading of nuts. The fixing frame 2 is used to fix the motor 3 to prevent it from moving randomly. The first gear 4 is a semi-gear with teeth on only half of it and a flat toothless part on the other half. The connecting frame 5 is used to connect the gear ring 6 and the first gear 4 to ensure their synchronous rotation. The gear ring 6 also has teeth on only half of it, and the teeth are on the side of the flat surface of the first gear 4. The rotating rod 7 is connected to the second gear 8 to ensure that the second gear 8 drives the rotating rod 7 to rotate synchronously. The connecting rod 9 is connected to the bottom of the rotating rod 7 and fits with its bottom to facilitate the simultaneous removal of the placement frame 10. The placement frame 10 is used to place nuts. The nuts are inserted into the round holes at the bottom of the placement frame 10 in sequence to keep them stable. The holes on the side of the placement frame 10 are for the nuts to be heated evenly. The heating rod 11 is electrically heated.

[0033] Refer to Figure 3 、 Figure 4 , the fixing component includes a housing 12. The right side of the housing 12 is fixedly connected to the lower left side of the rotating rod 7. The inner wall of the housing 12 is fixedly connected with a sliding rod 13. A spring 14 is sleeved on the outer wall of the sliding rod 13. The right end of the spring 14 is fixedly connected with a plug rod 15. The upper side of the outer wall of the plug rod 15 is rotatably connected with a push rod 16. The top end of the push rod 16 is rotatably connected with a baffle 17. The outer side of the baffle 17 is fixedly connected with a pull rod 18. The outer periphery of the baffle 17 is slidably connected to the inner wall of the housing 12. The outer part of the pull rod 18 is slidably connected to the upper inner part of the housing 12. The left end of the spring 14 is fixedly connected to the inner side wall of the housing 12. The inner part of the plug rod 15 is slidably connected to the outside of the sliding rod 13. The outside of the plug rod 15 penetrates through the housing 12 and the rotating rod 7 and is inserted into the connecting rod 9.

[0034] Specifically, the housing 12 is used to fix and protect the internal parts. The sliding rod 13 is used to control and limit the movement direction of the plug rod 15 to ensure that the plug rod 15 can only move left and right without random movement or wobbling. The spring 14 is fixed at both ends. By compressing the spring 14, the normal operation of the plug rod 15 is ensured. The push rod 16 is used to compress the spring 14. Under the limitation of the housing 12, the baffle 17 can only move up and down. The pull rod 18 is connected to the baffle 17. When the pull rod 18 is pulled, with the cooperation of all parts, the plug rod 15 will disengage from the connecting rod 9, achieving the functions of quick removal and quick fixation.

[0035] Working principle: When using this device, the connecting rod 9 needs to be removed. First, pull the pull rod 18. The pull rod 18 drives the baffle 17 to move upward. The baffle 17 drives the push rod 16 to align and pull the plug rod 15, so that the plug rod 15 is disengaged from the connecting rod 9. Then, pull out the connecting rod 9. Insert the nuts into the round holes at the bottom of the placement frame 10 in sequence outside. After insertion, reinstall the connecting rod 9. At this time, release the pull rod 18. Under the limit of the sliding rod 13, the spring 14 pushes the plug rod 15, pops out the plug rod 15 and inserts it back into the inside of the connecting rod 9 to achieve fixation. Then, close the door on the front side of the heating box 1. Control the heating rod 11 and the motor 3 to work through an external power supply. When the motor 3 rotates, it drives the first gear 4 to rotate. The first gear 4 drives the second gear 8 to rotate. Since the first gear 4 is a half gear, after the first gear 4 rotates half a circle, the second gear 8 will disengage from the first gear 4 and immediately engage with the gear ring 6 connected to the first gear 4 through the connecting frame 5, realizing the reverse rotation of the second gear 8. As long as the motor 3 keeps rotating, the second gear 8 will keep rotating reciprocally, driving the rotating rod 7 to rotate synchronously. The connecting rod 9 will continuously drive the placement frame 10 to rotate reciprocally in the heating box 1, making the nuts heat more evenly.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
