By arranging the welding assembly 32, after the sheet metal part body 3115 is clamped and fixed, when the sheet metal part body 3115 needs to be welded, the operator opens the air cylinder 328 to drive the output end of the air cylinder 328 to push the welding box 329 and the welding head 3210 to move downward, so that the welding head 3210 is attached to the surface of the sheet metal part body 3115. Then, the operator opens the welding box 329 to make the welding head 3210 weld the surface of the sheet metal part body 3115. When the transverse welding position of the surface of the sheet metal part body 3115 needs to be adjusted, the operator opens the electric push rod 323 to drive the displacement frame 324 to slide horizontally in the inner wall of the U-shaped frame 322, so as to adjust the transverse welding position of the welding head 3210 on the surface of the sheet metal part body 3115. When the longitudinal welding position of the surface of the sheet metal part body 3115 needs to be adjusted, the operator opens the drive motor 325 to drive the drive motor 325 to rotate with the lead screw 326. After the lead screw 326 rotates, the sleeve block 327 moves, which facilitates the adjustment of the longitudinal welding position of the welding head 3210 on the surface of the sheet metal part body 3115.

[0025] Further, the bottom of the mounting plate 1 is fixedly connected with four support legs 2, the four support legs 2 are equal in size, and the four support legs 2 are fixedly connected to the four corners of the bottom of the mounting plate 1.

By arranging two L-shaped extrusion plates 318, the metal plate body 3115 to be welded can be clamped and fixed, and the stability of the metal plate body 3115 during welding is improved.

[0028] Working principle: In the process of welding the metal plate, in order to ensure the stability of the metal plate during welding, the metal plate needs to be clamped and fixed. At this time, the operator places the metal plate in the middle above the mounting plate 1, then turns on the forward and reverse motor 312 to rotate the output shaft 313. During the rotation of the output shaft 313, the gear 314 rotates and engages with the rack 315, causing the rack 315 and the limiting block 317 to move. When the limiting block 317 slides on the inner wall of the limiting groove 316, the L-shaped extrusion plate 318 moves. When the two L-shaped extrusion plates 318 are close to each other, the side wall will be in contact with the outer wall of the metal plate. Through the extrusion force of the L-shaped extrusion plates 318 on both sides of the metal plate, the metal plate can be clamped and fixed, thereby improving the stability of the device during welding of the metal plate.

[0029] Before the L-shaped extrusion plate 318 clamps the metal plate body 3115, in order to facilitate the clamping and fixing of metal plate bodies 3115 of different thicknesses and improve the welding effect, the operator rotates the adjusting block 3112 to rotate the screw 3111. During the rotation of the screw 3111, the rectangular block 3113 moves along the inner wall of the rectangular groove 319. During the movement of the rectangular block 3113, the support block 3114 moves, thereby adjusting the support height of the support block 3114 to the metal plate body 3115, facilitating the clamping and fixing of metal plate bodies 3115 of different thicknesses and improving the welding effect.

[0030] When the sheet metal body 3115 needs to be welded, the operator opens the air cylinder 328 to make the output end of the air cylinder 328 push the welding box 329 and the welding head 3210 to move downward, so that the welding head 3210 is attached to the surface of the sheet metal body 3115, then the operator opens the welding box 329 to make the welding head 3210 weld the surface of the sheet metal body 3115, when the transverse welding position of the surface of the sheet metal body 3115 needs to be adjusted, the operator opens the electric push rod 323 to make the displacement frame 324 slide horizontally on the inner wall of the U-shaped frame 322, so as to adjust the transverse welding position of the surface of the sheet metal body 3115, when the longitudinal welding position of the surface of the sheet metal body 3115 needs to be adjusted, the operator opens the driving motor 325 to make the driving motor 325 rotate with the lead screw 326, after the lead screw 326 rotates, the sleeve block 327 moves, and in the process of moving of the sleeve block 327, the longitudinal welding position of the surface of the sheet metal body 3115 is adjusted.
