[0019] The two side doors 12 can be placed on the rolling components 3 at both ends of the table panel 1 to facilitate pushing the side doors 12 to move and to facilitate overlapping and aligning the two side doors 12. The side doors 12 can contact the telescopic clamping parts 5 during movement and automatically squeeze the telescopic clamping parts 5 to avoid affecting the movement of the side doors 12. After the two side doors 12 are moved and aligned, the two telescopic clamping parts 5 can be driven by the double-slide linear module 4 to approach each other to clamp and fix the two side doors 12. At the same time, the overlapping parts of the two side doors 12 are located directly below the X-shaped plate 9, which is convenient for fixing. At this time, the X-shaped plate 9 can be driven down by the electric push rod 8 to make the four pressure-suction components 10 press on the two side doors 12 respectively, and the hinge welding position is positioned, which is convenient for welding the hinges on the two side doors 12. During welding, air can be extracted through the exhaust pipe 11, and the smoke generated during welding can be extracted through the pressure-suction component 10 to ensure the breathing environment around welding and the breathing health of workers.

[0020] In a preferred embodiment, the rolling assembly 3 includes a first vertical plate 301 , a second vertical plate 302 , and a roller 303 rotatably mounted on an outer wall on an opposite side of the first vertical plate 301 and the second vertical plate 302 .

[0021] It should be noted here that the side door 12 is placed on the roller 303 for easy movement.

[0022] In a preferred embodiment, the telescopic clamp 5 includes a shell 501, a lifting block 502 slidably connected to the inner wall of the shell 501, and a first spring 503 arranged in the shell 501, and the top of the first spring 503 is connected to the bottom of the lifting block 502, and the bottom of the first spring 503 is connected to the bottom inner wall of the shell 501.

[0023] It should be noted here that: during the movement, the side door 12 contacts the lifting block 502 and squeezes the lifting block 502 into the shell 501, which does not affect the movement of the side door 12. After the side door 12 moves and overlaps, the lifting block 502 is reset and extended under the action of the first spring 503, which facilitates the clamping of the side door 12.

[0024] In a preferred embodiment, the pressure-suction assembly 10 includes a tube body 1001 , an air suction shell 1002 connected to the bottom of the tube body 1001 , and a second spring 1003 sleeved on the outside of the tube body 1001 .

The air intake shell 1002 can play a positioning role in the folding welding position. At the same time, during welding, air can be exhausted through the exhaust pipe 11, and the smoke generated during welding can be sucked into the tube body 1001 through the air intake shell 1002 and then exhausted.

[0026] Working principle: The two side doors 12 can be placed on the rolling components 3 at both ends of the table panel 1, which is convenient for pushing the side doors 12 to move and aligning the two side doors 12. The side doors 12 come into contact with the lifting block 502 during the movement, and the lifting block 502 is squeezed into the shell 501 without affecting the movement of the side doors 12. After the side doors 12 are moved and overlapped, the lifting block 502 is reset and extended under the action of the first spring 503, which is convenient for clamping the side doors 12. After the two side doors 12 are moved and aligned, the two lifting blocks 502 can be driven by the double-slide linear module 4 to approach each other to align the two side doors. The door 12 is clamped and fixed, and the overlap of the two side doors 12 is located directly below the X-shaped plate 9, which is convenient for fixation. At this time, the X-shaped plate 9 can be driven down by the electric push rod 8, and the descent of the X-shaped plate 9 drives the air intake shell 1002 to descend and contact the side door 12. The air intake shell 1002 is pressed onto the side door 12 by the second spring 1003. The air intake shell 1002 can play a positioning role in the folding welding position. At the same time, during welding, air can be exhausted through the exhaust pipe 11, and the smoke generated during welding can be drawn into the tube body 1001 through the exhaust shell 1002 and then exhausted, ensuring the breathing environment around the welding and ensuring the breathing health of the workers.
