After the wheel hub is fixed, the turntable 10 is rotated, driving the second lead screw 9 through the slide block 11 and the mounting bracket 13 to drive the laser... The welding torch 14 moves back and forth along the guide rod 12, thereby moving the laser welding torch 14 directly above the spokes and rim. Then, the first motor 4 is started, driving the first lead screw 5 to move the laser welding torch 14 downward to a suitable position directly above the spokes and rim under the action of the slider 6 and the connecting frame 7. Then, the laser welding torch 14 and the second motor 29 are started. Under the action of the laser welding torch 14, the connection position between the spokes and the rim is welded. Under the action of the second motor 29, the connecting shaft 30 is driven to rotate the entire hub under the action of the sleeve 31, thereby enabling the laser welding torch 14 to quickly weld the connection position between the spokes and the rim.
