[0019] The rotating frame driving mechanism 5 includes a worm gear 51, a first stepper motor 52 and a worm 53. The first stepper motor 52 is installed on the top support of the frame 1, and the worm 53 is fixed on the output shaft of the first stepper motor 52. The worm gear 51 is sleeved and fixed on the rotating frame 2, and the worm 53 is meshed with the worm gear 51. The first stepper motor 52 is electrically connected to the external PLC controller. The sheet metal to be welded is placed on the placement table 3. The output shaft of the first stepper motor 52 drives the worm 53 to rotate, and the worm 53 is meshed with the worm gear 51 for transmission.
