[0016] The following is combined with Figure 1-4 The utility model is further described as follows:

[0017] An automatic slot-finding and denting device for nuts includes a slot-finding and denting mechanism, which is connected to a rotary drive mechanism via a mounting plate b10 at the bottom. The rotary drive mechanism drives the slot-finding and denting mechanism to rotate. During the rotation of the slot-finding and denting mechanism, the position of the keyway on the screw is determined, and then the thin edge of the nut at the corresponding position of the keyway is dented to prevent the nut from loosening. The linear drive mechanism drives the slot-finding and denting mechanism to move linearly via the mounting plate a3. The linear drive mechanism is located on the bottom plate 1. The linear drive mechanism drives the slot-finding and denting mechanism to move to the position of the nut and screw to perform the slot-finding and denting operation.

[0018] The grooving and denting mechanism includes a large cylinder 32 fixed on the mounting plate c12, and the mounting plate c12 is rotatably connected to the shell 11 through the rotating shaft a16. The large cylinder 32 can rotate flexibly during operation to avoid damage to the large cylinder 32 caused by the rigid connection. The bottom of the shell 11 is fixed on the mounting plate b10. The cylinder head a18 of the large cylinder 32 is connected to the rotating shaft b17. The two ends of the connecting rod a13 are rotatably connected to the rotating shaft c19 and the rotating shaft b17 respectively. The rotating shaft c19 is located on the shell 11. The two ends of the connecting rod b14 are rotatably connected to the rotating shaft b17 and the rotating shaft d20. One end of the rocker arm 15 is rotatably connected to the rotating shaft d20. The rocker arm 15 is rotatably connected to the shell 11 through the rotating shaft e21. The end of the rocker arm 15 is provided with a denting head 22. When denting, the large cylinder 32 The cylinder head a18 pushes the rotating shaft b17 upward to drive the connecting rod a13 and the connecting rod b14 to rotate. The connecting rod b14 drives the rocker arm 15 to rotate counterclockwise. The denting head 22 on the rocker arm 15 moves toward the nut in the nut seat 28 to dent the nut. The denting head 22 is located on the outside of the opening of the nut seat 28. When the denting head 22 dents the nut, the thin edge of the nut is dented along the opening and enters the keyway of the screw. A groove-finding hook 26 is provided on the inside of the opening. The groove-finding hook 26 is connected to the connecting plate 33. The connecting plate 33 is rotatably connected to the outer shell 11 through the rotating shaft g31. The connecting plate 33 is rotatably connected to the cylinder head b25 of the small cylinder 24. The small cylinder 24 is rotatably connected to the cylinder seat 23 through the rotating shaft f27. The cylinder seat 23 is fixed on the outer shell 11. When searching for grooves, the small cylinder 24 drives the connecting plate 33 to rotate counterclockwise, so that the groove-finding hook 26 is pressed against the outer wall of the screw, and the rotary drive mechanism drives the groove-finding mechanism to rotate, so that the groove-finding hook 26 moves circumferentially along the outer wall of the screw. When it moves to the keyway on the outer wall of the screw, the groove-finding hook 26 enters and is stuck in the keyway, the rotary drive mechanism stops, and the groove-finding hook 26 stops in the keyway, completing the groove-finding positioning. The denting head 22 on the opposite side of the groove-finding hook 26 is opposite to the keyway, and the small cylinder 24 drives the groove-finding hook 26 to rotate clockwise, leaving the keyway and turning to the bottom of the keyway to make way for the denting of the thin edge of the nut. All preparatory actions before denting have been completed.

[0019] The rotary drive mechanism includes a rotating shaft 6 driven by a rotary cylinder 9. The rotating shaft 6 extends through and rotatably connects to an electrical slip ring 30 and bracket a4. The top of the rotating shaft 6 is connected to the mounting plate b10. The rotating cylinder 9 is connected to the rotating shaft 6 via a coupling 8 and secured to the mounting plate a3 via bracket b7. The rotating shaft 6 is rotatably connected to the bracket a4 via a bearing 5, which is secured to the mounting plate a3. The rotating cylinder 9 drives the rotating shaft 6, which in turn drives the mounting plate a3, which in turn drives the groove-finding mechanism mounted thereon. This causes the groove-finding hook 26 to move circumferentially along the outer wall of the screw, performing the groove-finding operation.

[0020] The linear drive mechanism includes a lift cylinder 29 secured to the base plate 1 via a cylinder frame. The output end of the lift cylinder 29 is connected to a mounting plate a3, which is slidably connected to the linear guide rail 2 on the base plate 1 via a slider. The lift cylinder 29 drives the mounting plate a3 up and down along the linear guide rail 2, which in turn drives the groove-finding mechanism mounted thereon up and down.

[0021] The working process of this utility model is as follows:

[0022] After the nut and screw are tightened and fixed, they are located above the grooving and denting mechanism. The screw passes through the nut, and the outer wall of the screw is provided with a keyway running through the upper and lower parts. The bottom of the screw is located below the thin edge of the nut. The lifting drive cylinder 29 drives the grooving and denting mechanism to move upward. After moving into position, the nut and screw are located in the nut seat 28. The small cylinder 24 drives the grooving hook 26 to rotate counterclockwise, so that the grooving hook 26 is pressed against the outer wall of the screw. The rotating cylinder 9 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the mounting plate b10 and the grooving and denting mechanism thereon to rotate, so that the grooving hook 26 moves circumferentially along the outer wall of the screw. When the grooving hook 26 moves to the keyway on the outer wall of the screw, the grooving hook 26 enters the keyway under the action of the small cylinder 24. Due to the limitation of the keyway, the groove-finding hook 26 cannot move further. The rotating cylinder 9 stops, and the groove-finding hook 26 stops in the keyway, completing the groove-finding operation. The keyway is now facing the opening of the nut seat 28 and the denting head 22. The small cylinder 24 drives the groove-finding hook 26 to rotate clockwise and move it below the keyway. The large cylinder 32 drives the denting head 22 through the opening of the nut seat 28 toward the thin edge of the nut, pressing the thin edge of the nut opposite the keyway into the keyway. This prevents the nut from rotating relative to the screw and prevents the nut from loosening. The nut denting and anti-loosening operation is completed.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
