[0070] Specific implementation process: when the four clamping plates 41 and the support block 42 clamp and fix the four panels of the metal cover, and at the same time the weld of the metal cover is aligned with the automatic welding mechanism 2, when welding is performed, the outlet mechanism 10 is operated, that is, the fan 102 is operated, so that negative pressure is formed inside the annular outlet cover 101, and then the inlet of the air inlet pipe 92 is sucked through the bellows 96, the air guide pipe 95, and the connecting pipe 91;

[0071] For the position where the weld seam is not welded, the electric push rods 941 on both sides of the unwelded weld seam are both operated, so that the push frame 942 is synchronously moved and rotated through the two push support rods 943 at one end thereof, and when the push support rods 943 are moving, the air suction block 931 connected to the synchronous support rods is rotated under the limiting action of the air inlet pipe 92, that is, the air suction block 931 is rotated at the axis of the air inlet pipe 92 until the air suction block 931 is rotated 45° relative to the air inlet pipe 92, at this time, the multiple air suction holes 9311 and the one air suction port 9312 on the air suction block 931 are respectively deviated from the position of the air inlet port 921 of the air inlet pipe 92, so that the air inlet pipe 92 is kept closed at this time;

[0072] For the weld positions that need to be welded, such as when spot welding is performed, the two electric push rods 941 on both sides of the corresponding welds are operated, so that the suction block 931 is rotated until the multiple suction holes 9311 at the suction block 931 are connected with the air inlet 921. At this time, spot welding can be performed. At the same time, during the spot welding process, the multiple suction holes 9311 can quickly suck the smoke at the spot welding position, and the sucked smoke enters the connecting pipe 91 through the air inlet pipe 92, and then enters the transfer cavity. Subsequently, the smoke enters the bellows 96 through the air guide pipe 95, and enters the inside of the annular outlet cover 101 through the bellows 96, and is finally exported to the external gas treatment equipment by the fan 102;

[0073] When arc welding is required, the electric push rod 941 is operated to rotate the air inlet 9312 of the air inlet block 931 to communicate with the air inlet 921, thereby achieving the effect of fully sucking the smoke generated during arc welding;

[0074] At the same time, in the present invention, when the support plate 3 is rotated to adjust its angle, the arrangement of the rotating ring 104 and the annular outlet cover 101 does not affect the suction of smoke and dust.

[0077] Therefore, when the four panels of the metal cover are placed on the outside of the support block 42 respectively, the four panels are aligned synchronously. At the same time, the two clamping blocks 412 at the corresponding panels are respectively under the reverse elastic action of the buffer spring 414, and the clamping blocks 412 respectively use the clamping ends 4121 thereon to preliminarily clamp and fix the panels of the metal cover and the outside of the support block 42, so as to facilitate the subsequent clamping plate 41 to further clamp and fix the panels of the metal cover.
