[0002] For the main welds of the steel structure box, the excessive current in gantry submerged arc welding can easily burn through the lower flat iron, so a root pass welding is required first. Currently, the commonly used root pass welding method is traditional manual gas shielded welding, which cannot weld multiple welds simultaneously, resulting in low construction efficiency. It is highly dependent on the experience of the workers and is greatly affected by their working conditions, leading to inconsistent welding quality. When poor construction quality is encountered, rework is inevitable, which will increase construction costs.

[0003] Chinese utility model patent CN215789824U discloses an intelligent welding robot for steel structure base welding, including a longitudinal track, a welding worktable, an intelligent welding robot, a welding torch, a longitudinal walking drive assembly, a walking shaft, a gantry, a cantilever, a positioning and clamping device, and a grinding device. The welding worktable has longitudinal tracks on both sides, and the gantry spans both sides of the welding worktable with its bottom slidably connected to the longitudinal tracks via the walking shaft. The longitudinal walking drive assembly drives the gantry. One end of the cantilever is slidably connected to the gantry laterally, and the other end is connected to the intelligent welding robot. The welding torch is connected to the end effector of the intelligent welding robot. The positioning and clamping device and the grinding device are respectively located on the front and rear sides of the gantry and can both move laterally. This technical solution can automatically perform grinding work and achieve workpiece positioning, clamping, and spot fixing, and can be well compatible with different sizes of similar workpieces. However, in this technical solution, two welding robots are mounted on the same robotic arm, and the horizontal and vertical adjustment distance is limited, which may cause inconvenience for operators. Utility Model Content

[0004] To address the problem that the horizontal and vertical adjustment distance is limited when two welding robots are mounted on the same robotic arm, which may cause inconvenience for operators, this utility model proposes an automatic bottom-welding robot for BOX boxes.

An electric telescopic arm is provided on the front side of the sliders. A welding assembly is provided at the end of the output shaft of the electric telescopic arm. Two sets of drive assemblies are provided on the sliders and the slide rail to drive the two sliders to slide left and right respectively. The gantry frame is equipped with a support assembly for supporting the components to be welded.

[0006] Furthermore, the front side of the slide rail is provided with a slide groove, and the upper and lower sides of the slide groove are symmetrically provided with trapezoidal protrusions extending towards the center line of the slide groove. The side of the slider is provided with a sliding protrusion that fits against the inner side of the slide groove.

[0007] Furthermore, the welding assembly includes a swing device disposed at the end of the electric telescopic boom and a controller disposed on the electric telescopic boom. The swing end of the swing device is provided with a gas welding torch, and the controller is configured in conjunction with the swing device and is electrically connected to the swing device.

[0008] Furthermore, the driving assembly includes a driving motor disposed on the opposite sides of the two sliders, a rack disposed on the upper side of the slide rail, and a gear disposed at the output end of the driving motor, the gear meshing with the rack.

[0009] Furthermore, the support assembly includes two trestles disposed below the gantry frame, the trestles having a trapezoidal cross-section.

[0010] Furthermore, the stool is a hollow structure, and vertical support ribs are arranged inside the stool and connected to the upper and lower sides of the stool cavity. The support ribs and the center line of the stool are located on the same vertical plane.

[0011] Compared with the prior art, this utility model has the following beneficial effects: This utility model realizes independent control of two sets of welding components through electric telescopic arm, slide rail, slider and drive component, which enables the operator to weld the components to be welded more flexibly, improves the flexibility and practicality of BOX box gantry automatic bottom welding robot, and can adjust different weld widths and welding swing speed through welding components, which can greatly reduce the labor intensity of the operator during welding, ensure the welding quality of the components to be welded and improve the welding efficiency of the operator during welding, and realize the support of the components to be welded through support component, ensuring the stability of the components to be welded during welding and ensuring the welding effect of the components to be welded.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figure 1 , Figure 2 As shown, the BOX box gantry automatic bottom welding robot includes a track 3 and a gantry frame 2 slidably connected to the track 3. The gantry frame 2 is welded from RHS200*10 square tubes and can support and move the entire equipment platform for work. The gantry frame 2 is slidably connected to each track 3 via pulleys 13. The component to be welded 1 is located inside the gantry frame 2. A slide rail 4 is bolted to the front side of the gantry frame 2. Two sliders 6 are slidably connected to the front side of the slide rail 4. An electric telescopic arm 5 is bolted to the front side of the slider 6, and the output direction of the electric telescopic arm 5 is vertically downward. A welding component is provided at the end of the output shaft of the electric telescopic arm 5. Two sets of drive components are provided on the sliders 6 and the slide rail 4 to drive the two sliders 6 to slide left and right respectively. The gantry frame 2 is equipped with a support assembly for supporting the component 1 to be welded.

[0016] In use, the operator can place the component to be welded 1 on the support assembly under the gantry 2 to ensure the stability of the component to be welded 1 during welding. Then, the operator can drive the two sliders 6 to move directly above the welding point of the component to be welded 1 by the drive assembly. After the movement is completed, the operator can control the extension and retraction of the electric telescopic rod to bring the welding assembly closer to the component to be welded 1 for welding. When the welding assembly is stacked on the component to be welded 1 for welding, the operator can also adjust the welding position by the drive assembly and the electric telescopic rod, which improves the convenience of the operator when welding the component to be welded 1, and thus improves the operator's work efficiency during welding.

[0017] In this embodiment, the front side of the slide rail 4 is provided with a slide groove, and the upper and lower sides of the slide groove are symmetrically integrally formed with trapezoidal protrusions extending towards the center line of the slide groove. The side of the slider 6 is provided with a sliding protrusion that fits against the inner side of the slide groove. In use, the cooperation between the trapezoidal protrusion and the slider 6 improves the connection strength of the slider 6 when connected to the slide rail 4, prevents the slider 6 from detaching from the slide rail 4 during operation, and ensures the reliability and stability of the slider 6 during operation.

[0018] In this embodiment, the driving assembly includes a drive motor 7 bolted to the opposite sides of two sliders 6. A rack 8 is bolted to the upper side of the slide rail 4. A gear 9 is mounted on the output end of the drive motor 7. The gear 9 meshes with the rack 8. In use, the operator can control the drive motor 7 to drive the gear 9 to rotate. Because the gear 9 is engaged with the rack 8, the gear 9 can drive the slider 6 to slide left and right along the slide rail 4 when it rotates, thereby realizing the adjustment of the left and right position of the welding assembly and improving the convenience of the operator when adjusting the left and right welding position.

[0019] Example 2 differs from Example 1 in that: like Figure 1 , Figure 2 As shown, the welding assembly includes a swing device 11 bolted to the end of the electric telescopic arm 5 and a controller 12 bolted to the electric telescopic arm 5. The swing end of the swing device 11 is equipped with a gas welding torch 10. The controller 12 is matched with the swing device 11 and is electrically connected to the swing device 11. The controller 12 and the swing device 11 are both existing technologies. Their specific structures and working principles are publicly available technologies that can be easily obtained by those skilled in the art. Therefore, they will not be described in detail here. The welding torch 10 adopts a straight-handle gas shielded welding wire torch head. The swing device 11 adopts a Zhongbaishi welding swing device 11. Its swing trajectory is an arc, which can swing around the center of a circle like a pendulum. It is mainly suitable for achieving different weld widths and swing speeds. It can greatly reduce the labor intensity of workers during welding, ensure the welding quality of workers when welding the components 1 to be welded, and improve the welding efficiency of workers during welding.

[0020] Example 3 differs from Example 1 in that: like Figure 2As shown, the support assembly includes two supports 14 placed under the gantry frame 2. The cross-section of the supports 14 is trapezoidal, and the supports 14 are made of HI300-15-20*300 steel to ensure the stability and reliability of the supports 14 when supporting the component 1 to be welded. At the same time, the trapezoidal structure of the supports 14 further improves the reliability and stability of the supports 14 when supporting, prevents the component 1 to be welded from shaking during welding, and ensures the welding effect of the component 1 to be welded.

[0021] In this embodiment, the stool 14 has a hollow structure, and vertically arranged support ribs are integrally formed inside the stool 14 and connected to the upper and lower sides of the inner cavity of the stool 14. The support ribs and the center line of the stool 14 are located on the same vertical plane. In use, the hollow stool 14 greatly reduces the weight of the stool 14, making it easier for workers to lift the stool 14 and improving the convenience of workers when moving the stool 14. At the same time, the support ribs inside the stool 14 can ensure the support strength of the stool 14, prevent the stool 14 from deforming during use, and improve the reliability of the stool 14 during use.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
