[0035] Working principle: When working, first open the box door 2 and place the workpiece inside the protective box 1 so that the workpiece contacts the middle of the outer side of the circular disk 20, and then start the second adjusting motor 28 to drive the adjusting screw 29 to rotate, and the adjusting screw 29 drives the second threaded sleeve 30 to move, and the second threaded sleeve 30 drives the connecting shaft 31 to move, and the connecting shaft 31 drives the movable bar 33 to move, and the movable bar 33 pushes the movable sleeve 25 to slide on the outside of the positioning slide rod 35 inside the bar groove 24 through the movable shaft 34, which can ensure that the movable sleeve 25 achieves better stability when moving. At the same time, the movable sleeve 25 drives the sliding block 22 to slide inside the sliding groove 23, and the sliding block 22 drives the clamping block 21 to move. At this time, the four clamping blocks 21 all move toward the center of the circular disk 20, and the four moving clamping blocks 21 are used to move the movable sleeve 25. The workpiece is fixedly clamped, and then the second adjusting motor 28 is stopped, and then the first adjusting motor 10 is started to drive the bidirectional screw 11 to rotate, the bidirectional screw 11 drives the first threaded sleeve 12 to move, and the first threaded sleeve 12 drives the positioning slide block 18 to slide inside the positioning slide groove 19, which can ensure that the first threaded sleeve 12 achieves better stability when moving. At the same time, the first threaded sleeve 12 drives the connecting seat 14 to move, the connecting seat 14 drives the movable frame 15 to move, the movable frame 15 drives the rotating motor 16 to move, the rotating motor 16 drives the circular shell 17 to move, the circular shell 17 drives the circular disk 20 to move, and the workpiece fixedly clamped on the outside of the circular disk 20 also moves accordingly. At this time, the two fixedly clamped workpieces move closer to each other, and after the two workpieces move and contact, the first adjusting motor 10 is stopped;

[0036] Then, the four welding robot arms 5 cooperate with each other to perform welding operations on the workpiece. During the welding operation, the rotating motor 16 can be started to drive the circular shell 17 to rotate, and the circular shell 17 drives the circular disk 20 to rotate. The workpiece fixedly clamped on the outside of the circular disk 20 also rotates accordingly. Then, the four welding robot arms 5 working in cooperation are used to perform welding operations on the adjusted and flipped workpiece. In this way, the welding workstation can adjust and clamp the workpiece during use, thereby facilitating better welding operations.

[0037] In addition, before performing the welding operation, the top of the connecting flange 41 is connected to the external ventilation duct, and then the fan 40 and the four welding robot arms 5 work synchronously during the welding operation. The fan 40 draws the smoke generated during welding inside the protective box 1 upward, and the smoke enters the interior of the smoke filter box 37 through the smoke inlet 38, and is filtered through the first filter 42 made of stainless steel filter mesh, the second filter 43 made of PTFE filter membrane, and the third filter 44 made of activated carbon filter mesh inside the smoke filter box 37. The smoke after three filtrations is transported to the inside of the external ventilation duct through the connecting flange 41 under the action of the fan 40, so that the welding workstation can be isolated from the outside air during use, and the smoke generated by welding can also be processed, so as to achieve better protection effect.
