Then the workpiece to be processed is placed on the Y-shaped support plate 73, wherein one end of the workpiece is close to the abutment in the fixed component 6. Then the cylinder 23 in the displacement component 2 is started so that the carrier 1 in the movable component 3 is displaced on the slide rail 31. The abutment on the transmission roller 34 in the movable component 3 abuts against the other end of the workpiece. Then, under the continuous movement of the movable component 3, the clamping and fixing of the workpiece to be processed is realized.

[0035] When the workpiece is fixed, the limit cylinder 4 on the movable part 3 is reset to cancel the limit lock on the abutting member in the movable part 3. Then the Y-shaped support plate 73 on the movable rail 72 is manually moved to adjust it to the middle position of the workpiece to achieve stable support for the workpiece.

[0036] Finally, the servo motor 63 in the fixed component 6 is started, and the active roller 62 is driven to rotate under the action of the belt member 64, and then the rotation adjustment of the workpiece to be processed is achieved with the cooperation of the transmission roller 34 in the movable component 3, so as to complete the efficient welding processing operation on the workpiece.
