The welding device for the production of the front cross beam assembly of the automobile roof is a device specially designed for welding the roof and the front cross beam during the automobile manufacturing process. The front cross beam is generally located at the front of the roof. In order to ensure the accurate assembly and efficient production of the front cross beam of the roof, the welding device needs to be able to accurately position the roof to prevent displacement when the front cross beam is welded to the automobile roof.

[0003] When welding the roof to the front cross beam, workers generally need to use positioning pins, clamps and other tools to accurately and stably limit the roof so that the roof can be stably restricted on the welding table to prevent the position of the roof from shifting during the welding process. During the welding process, the welding area of ​​the roof will be affected by high temperature, resulting in thermal expansion of the metal. The roof is generally in direct contact with the welding table, which makes it easy for the contact point between the roof and the welding table to affect the heat distribution of the weld and the metal melting process, so that the heat conduction of the roof is prone to uneven temperature due to the contact point, resulting in stress concentration, which is easy to cause deformation or cracks in the welding part.

[0032] In specific implementation, according to Figure 1-Figure 3 , Figure 5 and Figure 8When the canopy body 101 is restricted above the welding table 1 for welding, the electromagnet 301 is powered off to disengage the electromagnet 301 from the magnetic attraction with the magnetic block 303. At this time, the staff can push the support plate 304 to drive the slider 302 to slide along the slide groove 33. The slide groove 33 is matched with the slider 302, so that the support plate 304 is not easy to shake or deviate when moving.

The hood 305 can move freely according to the welding position of the canopy body 101, and the folding bellows 307 can maintain appropriate tightness during movement through the connected spring 309 to prevent the folding bellows 307 from falling to the ground. When the smoke hood 305 moves to above the welding position of the canopy body 101, the electromagnet 301 is energized again to make the electromagnet 301 and the magnetic block 303 magnetically attracted, so that the smoke hood 305 is restricted above the welding position of the canopy body 101, and then the fume purifier 308 is started to absorb the fume generated at the welding position of the canopy body 101 through the fixed tube 306, the folding bellows 307 and the smoke hood 305, so that the harmful gases of welding fume can be effectively removed when the welding device for the production of the front cross beam assembly of the automobile canopy is operated, so that the working environment of the staff is not easily polluted by welding fume.

[0033] In summary, when the canopy body 101 is welded to the front crossbeam, the canopy body 101 is placed on the upper side of the welding table 1, and the driving motor 2 is started to make the clamping plate 207 squeeze and clamp the four sides of the canopy body 101. At the same time, the pressing plate 215 on the lower side of the clamping plate 207 can lift the canopy body 101 upward, so that the canopy body 101 can be suspended in the air for limiting, to prevent stress concentration at the welding part of the canopy body 101, so that the weld of the canopy body 101 is not easy to deform or crack. When welding is performed above the platform 1, the support plate 304 is pushed to drive the smoke hood 305 to move to the top of the welding part of the canopy body 101, and the smoke purifier 308 is started to absorb the smoke generated at the welding part of the canopy body 101, so that the smoke purifier 308 can effectively remove the harmful gases of the welding smoke when the welding device for the production of the front cross beam assembly of the automobile canopy is operated, so that the working environment of the staff is not easily polluted by the welding smoke.
