[0002] An automatic bolt removal mechanism is a device that can automatically complete the bolt removal work. This mechanism is widely used in multiple fields. In industrial production, such as the automobile manufacturing assembly line, it can automatically remove bolts on components, improving production efficiency. In terms of mechanical equipment maintenance, it can replace manual labor to complete the removal of a large number of bolts in complex equipment, saving time and manpower. In addition, in some occasions where components need to be frequently replaced, such as mold manufacturing, it also plays an important role in ensuring efficient and accurate bolt removal operations.

[0003] However, due to the wide variety of bolt models, the automatic bolt removal mechanism often needs to replace different types of removal tools according to actual needs during use. The existing bolt removal mechanism is relatively complex when replacing the removal tool, and each time the tool is replaced, the operator needs to perform cumbersome steps, such as disassembling fixed parts and recalibrating, etc. Therefore, there is an urgent need for an automatic bolt removal mechanism that can quickly replace the removal tool. Summary of the Utility Model

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 the embodiments.

[0021] Refer to Figures 1-3 , the automatic bolt removal mechanism includes a fixed disk 1. The fixed disk 1 is rotationally connected to a turntable 2 through a first motor 3. A plurality of sleeves 4 are symmetrically installed on the bottom surface of the turntable 2. A disassembly shaft 5 is threadedly connected to each sleeve 4. An internal thread 10 is provided on the inner wall of each movable cavity 11. An external thread 6 is provided on the outer side of each disassembly shaft 5. And each internal thread 10 meshes with the corresponding external thread 6. When the disassembly shaft 5 rotates, the disassembly shaft 5 can be driven to rotate spirally upward or downward through the cooperation of the external thread 6 and the internal thread 10;

[0022] Each sleeve 4 drives the disassembly shaft 5 to rotate in the sleeve 4 through a driving structure. The driving mechanism includes a plurality of telescopic rods 13. An activity cavity 11 is provided in each sleeve 4. And each telescopic rod 13 is fixedly installed on the top wall of the activity cavity 11. The bottom ends of the plurality of telescopic rods 13 are jointly installed with a fixed plate 14. A second motor 12 is fixedly installed on the bottom surface of each fixed plate 14. And the output shaft of the second motor 12 is connected to the top end of the corresponding disassembly shaft 5. It is worth noting that the fixed plate 14 is limited by the plurality of telescopic rods 13 so that it cannot rotate. At the same time, when the second motor 12 is started, the disassembly shaft 5 slides upward, which will push the second motor 12 to slide upward synchronously. Furthermore, the telescopic rod 13 is compressed. At the same time, due to the self-locking property of the thread, when the position of the disassembly shaft 5 is fixed, it will not fall off from the sleeve 4;

[0023] An assembly seat 7 is fixedly installed at the bottom end of each disassembly shaft 5. A disassembly tool 8 is fixedly installed at the bottom ends of the plurality of assembly seats 7. Two clamping plates 19 are symmetrically and slidably connected in one of the assembly seats 7. A plurality of sawteeth 9 are fixedly installed on the outer side of each clamping plate 19. And the shape of each clamping plate 19 is arc-shaped. The arc-shaped clamping plate 19 can increase the contact area between the clamping plate 19 and the bolt. At the same time, the sawteeth 9 can increase the friction between the clamping plate 19 and the bolt, thereby facilitating the rotation of the bolt;

[0024] One of the assembly seats 7 drives two clamping plates 19 to slide symmetrically through a transmission mechanism. The transmission mechanism includes a third motor 15, and the third motor 15 is fixedly installed on the outside of the assembly seat 7. The output shaft of the third motor 15 penetrates through the assembly seat 7 and is connected with a double-headed screw rod 17. Two threaded sleeves 18 are symmetrically threadedly connected to the double-headed screw rod 17, and each threaded sleeve 18 is slidably connected within the assembly seat 7. Each clamping plate 19 is fixedly installed on the top surface of the corresponding threaded sleeve 18. A plurality of limiting rods 16 are symmetrically installed within the corresponding assembly seat 7, and each threaded sleeve 18 is slidably connected to the limiting rod 16. The limiting rod 16 limits the threaded sleeve 18 so that it cannot rotate and can only perform linear movement. At the threaded connection of the two ends of the double-headed screw rod 17 with opposite thread directions, it is the center of the double-headed screw rod 17, so as to ensure that the two threaded sleeves 18 slide towards each other.

[0025] When the present utility model is in use, first, an external device is used to identify and determine which tool is needed. Then, the first motor 3 is started to drive the turntable 2 to rotate, adjust the tool to the specified position, and the second motor 12 is started. The second motor 12 drives the disassembly shaft 5 to rotate. At the same time, since the disassembly shaft 5 is threadedly connected to the sleeve 4, when the disassembly shaft 5 rotates, it also rotates upward, and then the bolt is removed by the saw teeth 9.

[0026] When encountering a bolt with an inner groove, the first motor 3 can be used to rotate the corresponding assembly seat 7 to the specified position. Then, the third motor 15 is started to drive the double-headed screw rod 17 to rotate. Through the cooperation of the plurality of limiting rods 16 and the threaded sleeves 18, the two clamping plates 19 are driven to slide towards each other, thereby clamping the bolt from the outside, and the friction force is increased by several saw teeth 9 to avoid slipping of the threads.

[0027] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
