[0032] 1. Start the electric telescopic rod to make the movable plate drive the friction tube to move to the left, so that the friction plate on the left side of the friction tube contacts the first friction plate, and then start the driving motor to rotate the driving rod.

[0034] 3. Then, the movable plate and the friction tube are pushed toward the second friction disk through the electric telescopic rod, so that the friction plate at the right end of the friction tube contacts the second friction disk. At this time, the driving motor is started again to rotate the driving rod. At this time, the friction tube will be driven to rotate, which will drive the sleeve to rotate. The rotating rod is rotated through the action of the end gear and the transmission gear, and the rotating rod is rotated through the action of the active pulley, the belt and the driven pulley. The rotation of the rotating rod drives the rotating gear to rotate. Under the action of the fixed gear, the rotating gear drives the welding table to rotate with the support column through the rotating rod, ensuring that the next set of transformer housings clamped and fixed at this time are rotated to the position below the laser welding assembly, so as to realize the rapid replacement and installation of the transformer and improve the welding efficiency of the transformer.
