A detachable connection is made, and then the first servo motor (203) is driven to rotate the first rotating shaft (204), thereby driving the first rotating plate (205), the first end plate (206) and the first support rod (207) to rotate to a desired angle. At the same time, the second servo motor (503) is driven to rotate the second rotating shaft (504), thereby driving the second rotating plate (505), the second end plate (506) and the second support rod (507) to rotate to a desired angle. Then, under the cooperation of the first linear drive component (3), the two ends of the spiral body can be respectively engaged with the first card slot (208) and the second card slot (508), thereby clamping the spiral body in the middle position between the first support rod (207) and the second support rod (507); Step 3: Adjust the height of the auxiliary support. The electric hydraulic cylinder (602) drives the hydraulic telescopic rod (603) to telescope and slide, thereby driving the top plate (604) to move vertically linearly, thereby driving the auxiliary support assembly (8) to fall vertically to the desired position. At the same time, the outer wall of the first limiting rod (605) can slide along the inner wall of the first limiting hole (606); Step 4, auxiliary support fitting, the adjustment motor (701) drives the adjustment rod (702) to rotate, thereby driving the left-handed thread (703) and the right-handed thread (704) to rotate, and then the left-handed thread (703) rotates and the left-handed ball nut (705) and the first adjustment hole (708) slide along the slide hole (7012), which can drive the first adjustment plate (707) and the first auxiliary support roller (803) to move linearly along the slide rail (7011) to fit the outer wall of the spiral body, and at the same time, the right-handed thread (704) rotates and the right-handed ball nut (706) and the second adjustment hole (7010) slide along the slide hole (7012), which can drive the second adjustment plate (709) and the second auxiliary support roller (806) to move linearly along the slide rail (7011) to fit the outer wall of the spiral body; Step 5: Welding is completed, and the third drive motor (903) is used to drive the third screw rod (904) to rotate, thereby driving the third slider (906) to move linearly to the desired position under the cooperation of the third ball nut (905) and the outer wall of the second limiting rod (907) and the inner wall of the second limiting hole (908); Step six, direction adjustment welding, the first steering motor (1001) is driven to rotate the first steering rod (1002), thereby driving the right-angle plate (1003) to rotate horizontally, and then the second steering motor (1004) is driven to rotate the second steering rod (1005), thereby driving the first swing arm (1006) to rotate vertically, and then the third steering motor (1007) is driven to rotate the third steering rod (1008), thereby driving the second swing arm (1009) to rotate vertically, and then the fourth steering motor (1010) is driven to rotate the fourth steering rod (1011), thereby driving the U-shaped plate (1012) to rotate. The fifth steering rod (1015) is driven to rotate by the fifth steering motor (1014), thereby driving the welding machine (1101) to rotate inside the U-shaped groove (1013), thereby driving the welding rod (1102) to align with the required welding position. At the same time, the spiral body can be driven to rotate under the action of the first servo motor (203) and the second servo motor (503) rotating in the same direction, and the first auxiliary support roller (803) rotates along the first auxiliary support shaft (802) and the second auxiliary support roller (806) rotates along the second auxiliary support shaft (805), thereby completing the welding operation between the spiral shaft and the spiral blades in the spiral body.
