[0028] As a preferred embodiment, the flat pad storage box 5 is equipped with a feeding spring 51 and a flat pad 52. The feeding spring 51 ensures that the flat pad 52 is always at the front end of the guide seat 31, thus ensuring the accuracy of the flat pad 52's feeding.

The second transmission shaft 334 is mounted on the second mounting base 337. The first transmission gear 333 and the second transmission gear 335 cooperate with each other. The sensor 338 is mounted above the first mounting base 336. The second motor 331 drives the first transmission gear 333 to rotate, thereby driving the second transmission gear 334 to rotate, realizing the synchronous rotation of the first conveyor block 32 and the second conveyor block 42, thus realizing the rotation of the flat pad 52 and the spring pad 62 to the same center position.

[0033] As a preferred embodiment, the nut locking sleeve 8 is provided with a nut mounting groove 81. The nut mounting groove 81 is provided to position the nut 14 before installation, thus preparing for the further installation of the nut 14.

[0034] In this invention, when the base code needs to be installed, the cooperation of motor 21, lead screw 22, and push block 23 causes push block 23 to push nut 14 along guide rail 26, through guide groove 24, and into nut mounting groove 81 of nut locking sleeve 8. Then, through flat pad storage box 5 and spring pad storage box 6, flat pad 52 is conveyed to guide seat 31 and spring pad 62 is conveyed to guide seat 41. Flat pad 52 is then pushed into flat pad groove 321 by feed spring 51, and spring pad 62 is pushed into spring pad groove 421 by feed spring 61. Subsequently, motor 331 drives the rotation of transmission gears 333 and 334, thereby driving conveyor block 32 and conveyor block 42 to rotate, causing flat pad 52 and spring pad 62 to coincide at the same center position. The reverse adjustment mechanism... If the position sensor 95 detects that the position of the adjusting gear 2 93 is incorrect, it indicates that the nut mounting slot 81 is not parallel to the conveying direction of the nut 14. At this time, the motor 2 331 drives the transmission gear 1 333 to rotate, which in turn drives the transmission gear 2 335 to rotate. When the sensor 94 detects that the position is at the rated position, it indicates that the nut mounting slot 81 is parallel to the conveying direction of the nut 14. At this time, the sensor 94 sends a signal to the controller, and the controller stops the motor 2 331. At this time, the nut 14, flat washer 52 and spring washer 62 are in a centered position. Then, the electric air gun 7 installs the nut 14, flat washer 52 and spring washer 62 on the screw in the shaft, thus realizing the positioning of the base code. Through the operation of the controller, the base code positioning and installation of the screw in the shaft can be performed sequentially.

[0035] By adopting the above technical solution, compared with the prior art, this utility model achieves automated installation of nuts, flat washers, and spring washers through the cooperation of nut pushing mechanism, flat washer pushing mechanism, spring washer pushing mechanism, and electric air gun. At the same time, through the setting of the reverse adjustment mechanism, the nut installation groove of the nut locking sleeve is always oriented towards the nut pushing direction, ensuring the conveying of the nut. And through the cooperation of conveyor block one and conveyor block two, the flat washer and spring washer can be automatically conveyed, so that the nut, flat washer, and spring washer can be conveyed to the same central position, preparing for the next step of installation.

[0036] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, are within the protection scope of this utility model.
