[0026] The welding device disclosed in the present invention includes a base plate 3 and a mobile platform 4 for controlling the movement of the base plate 3. The mobile platform 4 is a platform capable of controlling the base plate 3 to move in two directions along the XY direction, with the length direction of the base plate 3 as the longitudinal direction and the direction perpendicular to it in the same plane as the transverse direction. The mobile platform 4 disclosed in the present invention includes a transverse motor, the output end of which is connected to the mobile plate, a cylinder is installed on the mobile plate, a push plate is connected to the output end of the cylinder, the push plate is relatively fixed to the base plate 3, and the cylinder can drive the push plate and the base plate 3 to move in the longitudinal direction. By adopting a two-way displacement method, the plane position of the base plate 3 can be adjusted, which is convenient for the operator to quickly position the first thin plate 1 and the second thin plate 2.

[0027] Specifically, the bottom plate 3 disclosed in the present invention is parallel to the horizontal plane, and the first thin plate limiting assembly 5 and the second thin plate limiting assembly 6 are relatively installed on the bottom plate 3, and the first thin plate limiting assembly 5 and the second thin plate limiting assembly 6 are respectively used to limit the ends of the first thin plate 1 and the second thin plate 2 that are away from each other, that is, the first thin plate limiting assembly 5 is used to limit the end of the first thin plate 1 away from the second thin plate 2 along the longitudinal direction, and the second thin plate limiting assembly 6 is used to limit the end of the second thin plate 2 away from the first thin plate 1 along the longitudinal direction, thereby controlling the overlapping area of ​​the first thin plate 1 and the second thin plate 2.

[0028] Furthermore, the first thin plate limiting assembly 5 of the present invention is also used to limit the bottom surface of the first thin plate 1, so that the first thin plate 1 can be kept horizontal before welding, and the second thin plate 2 is arranged parallel and spaced at the lower side of the first thin plate 1; a rectangular groove 7 is opened in the middle of the bottom plate 3, and a support plate 8 is arranged in the groove 7 along the vertical sliding direction. Under the limiting cooperation of the groove 7, the support plate 8 can slide vertically. A lifting and adjusting device for controlling the lifting and lowering of the support plate 8 is installed between the support plate 8 and the bottom plate 3, and the first thin plate 1 is placed on the support plate 8 at the same time. A welding assembly 9 for welding the first thin plate 1 and the second thin plate 2 is also installed on the bottom plate 3.

When the first thin plate 1 and the second thin plate 2 are being welded, the molten pool can enter into the gap between the first thin plate 1 and the second thin plate 2, thereby increasing the area of ​​the weld formed, thereby increasing the firmness of the two hardware accessories when spliced.

[0030] In some other embodiments, the lifting and adjusting device can directly use a jack, which is installed at the bottom of the groove 7, and the output end of the jack is connected to the support plate 8, which can drive the support plate 8 to move up and down.

The locking member 15 adopts a screw, and the inner end of the screw extends into the threaded hole provided on the clamp seat 11. The clamp seat 11 and the push seat 10 can be locked by the screw. A limiting groove 30 is provided on the clamp seat 11 of the present invention toward the side of the first thin plate 1, which can cooperate with the TT-shaped slide groove 13 to limit the first thin plate 1 and ensure the stability of the limiting support.

[0035] During the specific action, the output end of the hydraulic cylinder 16 acts on the limit frame 18, and the limit frame 18 deflects around the rotating shaft 19. After the rotating shaft 19 deflects, it drives the LL-type connecting rod 22 to deflect around the pin 23. The LL-type connecting rod 22 can drive the supporting connecting rod 21 to move as a lever, thereby driving the push seat 10 to move along the longitudinal direction.
