The output shaft of the second motor 14 is connected to the rod end of the worm 13. When the device is used, the workpiece to be welded is first placed above the lower support plate 6, and then the first motor 10 and the second motor 14 are started at the same time. The rotation of the first motor 10 drives the sprocket 8 to rotate, and the sprocket 8 drives the chain 9 to transmit. At this time, the lower support plate 6 is pulled upward, and the high support plate 6 is put down at the same time, so as to realize the lifting of the plate, and the second motor 14 drives the worm 13 to rotate when it rotates, and the worm wheel 12 rotates under the drive of the worm 13, so that the turntable 11 The support frame 3 is driven to rotate as a whole, and the single rotation angle of the support frame 3 is 180°.
