[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0023] See Figures 1-4This embodiment provides a gantry welding device, including a base 1, which serves as the basic support structure for the entire gantry welding device, providing stable support. A control box 2 is fixedly connected to the upper end of the base 1. The control box 2 houses the overall machine control system. A gun head controller 3 is located at the upper end of the base 1, responsible for controlling the movement of the welding gun head. A platform Y-axis 4 and a platform rotation axis 5 are also provided. A position adjustment mechanism is located on the outer wall of the control box 2. The position adjustment mechanism includes a motor A61, which is fixedly connected to the outer wall of the control box 2. A threaded rod A6 is fixedly connected to the output end of the motor A61. 2. The outer wall of the threaded rod A62 is threadedly connected to a cross-shaped X-axis 63. The outer wall of the cross-shaped X-axis 63 is fixedly connected to a fixing block 64. The outer wall of the fixing block 64 is rotatably connected to a threaded rod B65. The outer wall of the threaded rod B65 is threadedly connected to a connecting block 8, which has certain heat resistance and strength to cope with the heat and force generated during the welding process. The front of the connecting block 8 is fixedly connected to a welding component 7. One end of the threaded rod B65 passes through the fixing block 64 and is fixedly connected to a worm gear 66. The outer wall of the cross-shaped X-axis 63 is provided with a receiving groove 67. The inner wall of the receiving groove 67 is rotatably connected to a worm gear 68.

[0024] The position adjustment mechanism also includes a motor B69, which is fixedly connected to the outer wall of the control box 2. The output end of the motor B69 is fixedly connected to a transmission rod 610. A limit rod 611 is fixedly connected to the outer wall of the transmission rod 610. A through hole is opened inside the worm gear 68, and a limit groove is opened on the inner wall of the through hole. The transmission rod 610 moves through the through hole, and the limit rod 611 is slidably connected to the inner wall of the limit groove.

[0025] The worm gear 66 is located on the front of the worm 68 and meshes with the worm 68.

[0026] In practical use, when the vertical position of the welding assembly 7 needs to be adjusted, the motor A61 is started to drive the threaded rod A62 to rotate. The cross-shaped X-axis 63, threaded onto the outer wall of the threaded rod A62, moves up or down on the outer wall of the transmission rod 610, thus adjusting the vertical position of the welding assembly 7. When the lateral position of the welding assembly 7 needs to be adjusted, the motor B69 is started to drive the transmission rod 610 to rotate. The limiting rod 611 on the outer wall of the transmission rod 610 rotates accordingly, and through the engagement of the limiting groove inside the worm gear 68, the worm gear 68 itself rotates. The meshing worm wheel 66 then rotates, which in turn drives the threaded rod B65 to rotate. The connecting block 8 threaded onto the threaded rod B65 then slides left and right along the cross-shaped X-axis 63, thus achieving lateral adjustment of the welding position. Example 2

[0027] See Figures 1-4Based on Embodiment 1, the platform rotation shaft 5 includes a fixed rod 51, which is fixedly connected to the upper end of the base 1. A disk 52 is fixedly connected to the upper end of the fixed rod 51. A rotation shaft 53 is rotatably connected to the bottom of the disk 52. The upper end of the rotation shaft 53 passes through the disk 52 and is fixedly connected to a rotating platform 54. A gear 55 is fixedly sleeved on the outer wall of the rotation shaft 53. An electric telescopic rod 56 is fixedly connected to the bottom of the disk 52. A toothed plate 57 is fixedly connected to the output end of the electric telescopic rod 56, which is responsible for driving the movement of the toothed plate 57.

[0028] The toothed plate 57 is located on the side of the gear 55 and meshes with the toothed plate 57.

[0029] The bottom of the disc 52 is fixedly connected to the slide rail 58, and the toothed plate 57 is slidably connected to the outer wall of the slide rail 58, providing a stable guide for the movement of the toothed plate 57, ensuring the smoothness of the toothed plate 57 during the sliding process, and reducing wear.

[0030] When the above equipment is used, if it is necessary to adjust the position of the workpiece on the upper end of the rotary table 54, the electric telescopic rod 56 is activated to drive the toothed plate 57 to slide on the outer wall of the slide rail 58. The gear 55 that meshes with it will rotate accordingly, and the rotating shaft 53 will rotate accordingly, which will drive the rotary table 54 to rotate, thereby driving the workpiece to rotate and thus changing the position of the workpiece.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
