[0034] like Figure 5 As shown, a gear 1001 is connected and fixedly arranged on the adjustment seat 10, and the gear 1001 is meshed with the rack 501 for transmission.

[0039] When the automobile transmission shaft 7 needs to be welded, the motor A401 is first used to drive the turntable 4 to rotate. At this time, the turntable 4 will drive the adjustment processing table 5 to move. At this time, under the action of the protrusion of the limiting ring groove 302, the rack 501 connected to the sliding rod 502 will move, thereby driving the adjustment seat 10 connected to the gear 1001 to rotate, so that the limiting transmission sleeve 6 is arranged in an inclined upward structure.

At the same time, the driving wheel 909 on the grinding brush wheel 901 drives the adjusting wheel 908 to rotate, so that the adjusting wheel 908 drives the impeller 906 connected to the universal joint B907 to rotate, so that the cleaning agent in the pretreatment seat 8 is sprayed on the welding surface of the automobile transmission shaft 7 through the flushing pipe 902 for flushing;

[0042] After cleaning, the turntable 4 rotates to move the automobile transmission shaft 7 to the bottom of the laser welding equipment 2, and the laser welding equipment 2 is used to weld the automobile transmission shaft 7. After welding, the turntable 4 rotates. At this time, when the limiting ring groove 302 protrudes inward, the rack 501 connected to the sliding rod 502 will move, thereby driving the adjustment seat 10 to rotate, so that the limiting transmission sleeve 6 is tilted downward. At this time, the limiting rod 605 is loosened, and the automobile transmission shaft 7 will automatically fall down under its own weight to complete the unloading.
