DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0036] With reference to Figure 1 , Figure 2 and Figure 4 , the utility model provides an embodiment: a bolt assembly tool, including shell 1 and connecting block 2, shell 1 end inside is provided with rotating assembly, and shell 1 both ends inside are provided with limit assembly, and connecting block 2 inside is provided with displacement assembly, and connecting block 2 outside is slidably connected with frame 3, and frame 3 inside is provided with positioning fixed assembly,

[0037] Rotating assembly includes gear two 14, gear two 14 is rotatably connected to the inside of shell 1, and the inside of shell 1 is also rotatably connected with gear one 13, and gear two 14 is engagedly connected to the outside of gear one 13, and the outside of shell 1 is fixedly connected with drive motor 15, and the output end of drive motor 15 is fixedly connected to the inside of gear two 14. When drive motor 15 is started, its output end drives gear two 14 fixedly connected thereto to rotate inside shell 1, since gear two 14 and gear one 13 are engaged with each other, the rotation of gear two 14 will be transmitted to gear one 13, so that gear one 13 rotates synchronously inside shell 1, thereby providing power for subsequent operation of bolt 9. The outside of shell 1 is fixedly connected with protective shell 16, and drive motor 15 is fixedly connected to the inside of protective shell 16. Protective shell 16 is used to protect the motor. A plurality of spring push rods 12 are fixedly connected to the inside of gear one 13, and the end of each spring push rod 12 is fixedly connected with positioning block 11. Through the pushing of spring push rod 12, positioning block 11 can position bolt 9 and push bolt 9 so that it can accurately cooperate with nut 8 to complete the assembly action.

[0038] With reference to Figure 2 and Figure 6, the limiting assembly includes a sliding groove block 10 fixedly connected to the inner side of the shell 1, a sliding rod 18 slidingly connected to the inner side of the sliding groove block 10, a spring 19 fixedly connected to the outer side of the end of the sliding groove block 10, a limiting block two 20 fixedly connected to the end of the sliding rod 18, and the end of the spring 19 fixedly connected to the inner side of the limiting block two 20. When the bolt 9 enters the inside of the shell 1, the sliding rod 18 slides in the sliding groove block 10, and the spring 19 absorbs the impact force generated when the bolt 9 enters, preventing the parts from excessive displacement due to impact, and playing a buffering role. After the bolt 9 enters, the limiting block two 20 limits the bolt 9 under the elastic force of the spring 19. During the rotation of the bolt 9, the limiting block two 20 provides buffering through the elastic force of the spring 19, ensuring the stability of the rotation of the bolt 9.

[0039] Referring to Figure 2 and Figure 5 , the positioning and fixing assembly includes two electric push rods 4, both of which are fixedly connected to the inner sides of the two ends of the frame 3, both of which are fixedly connected to the end of the electric push rod 4. The fixed block 5, both of which are fixedly connected to the end of the fixed block 5. One end of the two fixed blocks 5 and the limiting block one 7 are slidingly connected to the inner sides of the two ends of the frame 3. The activated electric push rod 4 will push the fixed block 5 fixedly connected to the end of the fixed block 5, so that the fixed block 5 slides along the inner sides of the two ends of the frame 3. Since the fixed block 5 is fixedly connected to the end of the limiting block one 7, the limiting block one 7 will move together with the fixed block 5 while the fixed block 5 slides, and both the fixed block 5 and the limiting block one 7 can slide in the inner sides of the two ends of the frame 3, ensuring their directionality and stability. When the limiting block one 7 moves to the predetermined position, it will contact the bolt to be assembled, providing stable positioning and fixing for the bolt assembly, which helps to improve the accuracy and reliability of the assembly. Both sides of the two limiting blocks one 7 are fixedly connected with anti-skid pads 17, and both sides of the two anti-skid pads 17 are slidingly connected with nuts 8. When the limiting block one 7 approaches the nut 8, the anti-skid pad 17 on the side of the limiting block one 7 contacts the side of the nut 8, clamping the nut 8 with friction force to realize the positioning and fixing of the nut 8, facilitating the assembly of the bolt 9 and the nut 8.

[0040] Referring to Figure 1 , Figure 2 and Figure 3The shifting assembly comprises two moving blocks 6, each of which is slidingly connected to the inner side of the two ends of the connecting block 2 and fixedly connected to the side of the frame 3. When the position of the frame 3 needs to be adjusted, the moving blocks 6 slide in the inner side of the two ends of the connecting block 2. Since the end of the moving block 6 is fixedly connected to the side of the frame 3, the sliding of the moving block 6 drives the frame 3 to shift on the outer side of the connecting block 2. This shifting can change the position of the frame 3, so that the whole tooling can adapt to different bolt assembly position requirements. The bolt 9 is slidingly connected to the inner side of the gear one 13, and a plurality of positioning blocks 11 are slidingly connected to the end of the bolt 9. When the bolt 9 needs to be assembled with the nut, the positioning blocks 11 can help determine the position of the bolt 9, ensuring that the bolt 9 is in the correct assembly position. At the same time, the positioning blocks 11 support or guide the bolt 9 to a certain extent, preventing the bolt 9 from shifting during assembly, ensuring the accuracy and reliability of the assembly.

[0041] Working principle: When the driving motor 15 is started, it drives the gear two 14 to rotate in the inner side of the housing 1, and the gear one 13 also rotates at the same time. The rotation of the gear one 13 provides power for the subsequent operation of the nut 8 and related components. The plurality of spring push rods 12 fixedly connected to the inner side of the gear one 13 move with the rotation of the gear one 13, thereby positioning the bolt 9 and pushing the bolt 9 so that it can accurately cooperate with the nut 8 to complete the assembly action, enabling the nut 8 to cooperate with the bolt 9 to complete the assembly action.

[0042] When the bolt 9 needs to enter the inside of the housing 1, the slide rod 18 slides in the sliding groove block 10, and the spring 19 can absorb part of the impact force to prevent excessive displacement of the components. After the bolt 9 has entered the inside of the housing 1, the limiting block two 20 is quickly brought to the bolt 9 under the elastic force of the spring 19 to limit the bolt 9. When the bolt 9 rotates, the limiting block two 20 can be effectively buffered by the elastic force of the spring 19.

[0043] When the position of the frame 3 needs to be adjusted, the moving block 6 slides in the connecting block 2, driving the frame 3 to shift on the outer side of the connecting block 2, thereby changing the position of the frame 3 to adapt to different nut 8 assembly position requirements. When the limiting block one 7 moves to the position of the nut 8, the non-slip pad 17 contacts the side of the nut 8, clamping and fixing the nut 8 by friction to position and fix the nut 8, facilitating subsequent assembly operations.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
