This arrangement can remove dust accumulated on the nut thread, and the linear rotating bushing 378 can rise and fall with the positioning plate, so the cleaning effect is good.

[0076] The working principle of the nut tightening mechanism 3 is as follows: when working, the material discharge seat 331 is moved to the material taking position through the translation assembly, the nut is placed in the material discharge seat 331, the translation assembly drives the material discharge seat 331 to move to the bottom of the tightening gun 34, and then the unlocking cylinder 338 is started to drive the unlocking push rod 332 to rise, and at the same time the lifting assembly 32 drives the screwdriver bit 35 to descend, the unlocking push rod 332 is inserted into the connecting sleeve 361, so that the buckle 362 is retracted inwardly into the screwdriver bit 35, when the screwdriver bit 35 is close to the nut, the tightening gun 34 rotates, and when the profiling portion 351 of the screwdriver bit is aligned with the inner twelve-angle hole of the nut, the screwdriver bit 35 slides into the nut, and the screwdriver bit 35 is inspected. The sensor 339 detects that the screwdriver bit 35 is inserted into the nut, and transmits a signal to the control system, which controls the tightening gun 34 to stop, unlocks the push rod 332 and descends, and the buckle 362 rotates horizontally to lock the bottom surface of the nut, and locks the nut at the lower end of the screwdriver bit 35. Then the lifting assembly 32 drives the tightening gun 34 to rise a certain distance, and the material discharge assembly 33 returns to the material collection position. Finally, the tightening gun 34 descends and starts to tighten the nut onto the workpiece. When the nut is screwed into the workpiece, the rotating shaft in the workpiece is inserted into the screwdriver bit 35, and the buckle 362 releases the lock on the nut. After the nut is screwed into place, the tightening gun 34 is reset to complete the assembly of the nut. In summary, the screwdriver bit 35 and the buckle locking assembly 36 can be used to lock the nut when taking materials, and the workpiece itself can be unlocked when tightening, so that the assembly of the inner polygonal nut can be automatically realized. The structure is simple, and the operation is convenient, fast and accurate.
