[0025] Working principle: During operation, rotate the appropriate clamping plate 21 according to the size of the workpiece, push the pressure rod 30 downward. The downward movement of the pressure rod 30 can drive the pressure ring 31 and the cross plate 28 to move downward. The pressure ring 31 can squeeze the second spring 32 to deform it. The cross plate 28 can drive the insertion rod 33 to move downward. Then insert the positioning plate 62 into the positioning groove 61 on one side of the clamping plate 21. At this time, the cross plate 28 is inserted into the socket 34. Release the pressure rod 30. The reset of the second spring 32 can drive the insertion rod 33 to reset, so that the insertion rod 33 is inserted into the insertion hole 35, and the clamping plate 21 can be fixed. Then place the workpiece on the top of the turntable body 11, start the second motor 54. The second motor 54 can drive the bidirectional screw 53 to rotate. The rotation of the bidirectional screw 53 can drive the two sliders 52 to move towards the middle. The sliders 52 can drive the moving plate 22 to move. The movement of the moving plate 22 can drive the clamping plate 21 to move, so that the clamping plate 21 contacts the workpiece, and the first spring 26 deforms accordingly. Using the elasticity of the first spring 26, the workpiece can be protected to prevent the workpiece from deforming. After fixing the workpiece, the first motor 44 can be started. The first motor 44 can drive the rotating shaft 43 and the gear 45 to rotate. The rotation of the gear 45 can drive the rack 46 to move vertically. The movement of the rack 46 can drive the turntable body 11 to move vertically, and the height of the workpiece can be adjusted to facilitate welding. Starting the third motor 91 can drive the drive shaft 92 to rotate. The rotation of the drive shaft 92 can indirectly drive the turntable body 11 to rotate, and thus the workpiece can be rotated to facilitate welding of the workpiece.
