[0028] A sliding seat 5 and a cleaning brush 6. The sliding seat 5 is threadedly connected to the threaded cross bar 4 and slidably connected to the guide frame 3. The cleaning brush 6 is fixedly connected to the top outer wall of the sliding seat 5. Uniformly distributed bristles are provided at the bottom of the cleaning brush 6, and all the bristles are in contact with the top of the intake grille welding table 1;

[0029] A servo drive assembly: It includes a first servo motor 7 fixedly installed on the side wall of the guide frame 3, a driving gear 8 fixedly sleeved on the output shaft of the first servo motor 7, and a transmission gear 9 fixedly sleeved on the threaded cross bar 4. The output shaft of the first servo motor 7 penetrates the guide frame 3, and the driving gear 8 meshes with the transmission gear 9;

[0030] In the specific implementation of this embodiment: The driving gear 8 is controlled by the first servo motor 7 to rotate. Subsequently, the transmission gear 9 meshing with the driving gear 8 will control the rotation of the threaded cross bar 4. Then, the sliding seat 5 threadedly connected to the threaded cross bar 4 and slidably connected to the guide frame 3 will drive the cleaning brush 6 to perform a linear motion, so as to quickly clean the impurities such as welding slag remaining on the surface of the intake grille welding table 1, ensure the cleanliness of the surface of the intake grille welding table 1, and facilitate subsequent use.

[0031] Embodiment 2, referring to Figures 1-2 and Figure 4 , this embodiment is optimized on the basis of Embodiment 1. Specifically: A welding device for processing intake grilles further includes a height adjustment mechanism, and the height adjustment mechanism includes:

[0032] A second servo motor 10, which is fixedly installed on the top outer wall of the base 17;

[0033] A bidirectional screw rod 11, which is coaxially and fixedly connected to the output shaft of the second servo motor 10 through a coupling. Two bearing seats 14 are sequentially fixedly connected to the top outer wall of the base 17, and the bidirectional screw rod 11 is rotatably installed between the two bearing seats 14;

[0034] Two movable blocks 12, which are symmetrically screwed onto the two opposite threaded ends of the bidirectional screw rod 11. A slideway 15 is formed on the top of the base 17, and the outer walls of the two movable blocks 12 are slidably connected to the inner wall of the slideway 15;

[0039] Secondly, the bidirectional screw 11 is driven by the second servo motor 10 to rotate forward and backward.

Furthermore, under the telescopic guidance of the four telescopic guide rods 16, the intake grille welding table 1 can perform a lifting motion, so as to facilitate the flexible adjustment of the height of the intake grille welding table 1 and better adapt to the feeding requirements of different feeding equipment and workers of different heights.
