Detailed Description of the Invention

[0017] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0018] As Figures 1-5As shown in the figure, an assembly tool for a locknut includes a box body 3, and also includes a fixed support arm 4 and a movable support arm 5. The fixed support arm 4 is arranged at the inner top of the box body 3. The movable support arm 5 can move along the inner wall of the box body 3. One end of the fixed support arm 4 is provided with a fixed groove 6 for accommodating the locknut 1. Both the upper and lower ends of the fixed groove 6 are open. The upper surface of one end of the movable support arm 5 is provided with a movable groove 7 for accommodating the head of the bolt 2. A rotating shaft 8 is arranged at the lower end of the movable groove 7. The rotating shaft 8 is rotatably connected to the movable support arm 5. A driven gear 9 is arranged at the lower end of the rotating shaft 8. A main gear 10 that is externally meshed with the driven gear 9 is arranged on the lower surface of the movable support arm 5. A protective shell 11 is arranged at the lower end of the movable support arm 5. A motor 12 for driving the main gear 10 to rotate is arranged inside the protective shell 11. A pull rod 13 is arranged on the upper surface of one end of the movable support arm 5. The upper end of the pull rod 13 penetrates through the upper ends of the fixed support arm 4 and the box body 3. A handle 14 is arranged at the upper end of the pull rod 13. A button 15 for controlling the motor 12 is arranged on the handle 14. A handle 16 is arranged on one side of the box body 3.

[0019] By assembling the locknut 1 and the bolt 2, the two parts are fixedly connected. Specifically, first, keep a relatively large distance between the movable arm 5 and the fixed arm 4 to facilitate placing the head of the bolt 2 into the movable slot 7 on the movable arm 5. The head of the bolt 2 abuts against the inner side wall of the movable slot 7. By controlling the rotation of the movable slot 7, the bolt 2 in the movable slot 7 can be driven to rotate. After the placement of the bolt 2 is completed, move the device to the position of the two parts to be connected by the handle 16, and make the two parts located between the bolt 2 and the fixed slot 6. Then place the locknut 1 into the fixed slot 6, and then make the fixed slot 6 buckle on the upper surface of the part above, so that the locknut 1 can always be located in the fixed slot 6. Both parts have through holes for the bolt 2 to pass through. By moving the device, align the threaded hole on the locknut 1 with the through hole on the part. Then drive the pull rod 13 to move upward by the grip 14. When the pull rod 13 moves upward, it will drive the movable arm 5 and the bolt 2 on the movable arm 5 to move upward. At the same time, press the button 15. After the button 15 is activated, the motor 12 is started. The motor 12 drives the main gear 10 to rotate. The meshing between the main gear 10 and the driven gear 9 drives the rotating shaft 8 to rotate, and drives the movable slot 7 at the upper end of the rotating shaft 8 and the bolt 2 in the movable slot 7 to rotate. The bolt 2 is directly below the locknut 1. When the bolt 2 moves upward, it is necessary to press down the handle 16 to make the fixed slot 6 stick to the part. Then the bolt 2 passes through the through hole on the part and is threadedly connected to the locknut 1. Then, by continuously controlling the rotation of the bolt 2, the bolt 2 and the locknut 1 are assembled and the two parts are fixed. After the assembly is completed, release the button 15, and the motor 12 stops rotating. Then control the movable arm 5 to move downward by the grip 14 to increase the distance between the movable slot 7 and the part. Then drive the whole device to move upward by the handle 16 to facilitate the separation of the fixed slot 6 from the locknut 1 and the bolt 2. Then move the device horizontally to remove the device from the part.

[0020] Furthermore, a fixed rod 17 is arranged inside the box body 3. The movable arm 5 is slidably connected to the fixed rod 17. The fixed rod 17 can increase the stability of the movable arm 5 when moving in the box body 3, reduce the inclination angle of the movable arm 5, thereby reducing the friction between the movable arm 5 and the inner wall of the box body 3, and improving the stability of the movement of the movable arm 5.

[0021] Furthermore, the fixed rod 17 is located between the handle 16 and the pull rod 13. When driving the movable arm 5 to move along the inner wall of the box body 3 by the pull rod 13, the fixed rod 17 can make the movement of the movable arm 5 more balanced, so that the bolt 2 in the movable slot 7 can stably complete the assembly with the locknut 1 in the fixed slot 6.

[0022] Furthermore, the number of teeth of the main gear 10 is less than that of the driven gear 9, which can achieve the function of reducing speed and increasing torque. At the same time, the motor 12 is selected as a motor 12 with a speed reducer to further reduce speed and increase torque, improving the rotation stability of the bolt 2 and the fastening performance of the connection between the bolt 2 and the locknut 1.

[0023] Furthermore, a spring 18 is sleeved on the pull rod 13. The spring 18 is located between the fixed support arm 4 and the movable support arm 5. After the assembly of the bolt 2 and the locknut 1 is completed, the movable support arm 5 can be quickly reset to facilitate the subsequent separation of the fixed slot 6 from the locknut 1 and the bolt 2.

[0024] When the device is in use, it can accurately position the positions of the bolt 2 and the locknut 1. When the assembly of the bolt 2 and the locknut 1 is realized, the bolt 2 can be accurately assembled with the locknut 1. And during the assembly, the fixed support arm 4 is attached to the upper surface of the part, and the part can support the fixed support arm 4. The staff only needs a relatively small force to keep the device balanced through the handle 16, and it also avoids holding the bolt 2 with a long arm, reducing the assembly difficulty and improving the assembly efficiency.

[0025] In the description of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
