[0030] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0031] like Figures 1 to 5As shown, an embodiment of this utility model provides a mobile welding device, including a ground rail assembly 10, a movable base 20, a support base 30, a welding robot 40, and a welding torch assembly 50. The ground rail assembly 10 has a multi-segment splicing structure. The movable base 20 is arranged to move back and forth along the extension direction of the ground rail assembly 10. The support base 30 is height-adjustable and is arranged on the movable base 20. The welding robot 40 is installed on the support base 30, and the welding torch assembly 50 is installed at the moving end of the welding robot 40. The movable base 20 drives the welding robot 40 to move along the ground rail assembly 10, and the welding robot 40 drives the welding torch assembly 50 to move.

[0032] In this design, the ground rail assembly 10 is a multi-segment splicing structure, which can be freely spliced ​​according to welding requirements, avoiding the need to fix the welding equipment to the ground and shortening the construction cycle. The movable base 20 can move back and forth along the extension direction of the ground rail assembly 10. The height of the support base 30 set on the movable base 20 is adjustable. The setting of the movable base 20 and the support base 30 allows the welding robot 40 set on the support base 30 to move to the corresponding position according to the welding requirements of the workpiece. At the same time, its welding height can be precisely adjusted. The welding operation is performed using the welding gun assembly 50 set at the moving end of the welding robot 40, which expands the welding range and improves the welding flexibility. In particular, it can meet the welding requirements of large workpieces and improve the applicability of this mobile welding equipment.

[0033] like Figure 4 As shown, the mobile welding equipment also includes a lifting assembly 60, which comprises a lifting seat 61, a lifting screw 62, and a lifting slide 63. The lifting seat 61 is mounted on the movable base 20, the lifting screw 62 is rotatably mounted on the lifting seat 61, and the lifting slide 63 is threadedly connected to the lifting screw 62. The support base 30 is connected to the lifting slide 63. By connecting the support base 30 and the lifting slide 63, the welding height of the equipment can be precisely adjusted according to different welding requirements, with an adjustment accuracy of ±0.1mm, ensuring that the welding robot 40 maintains precise welding operations at different heights.

[0034] In this embodiment, the lifting assembly 60 further includes a lifting motor 64 and an adjusting handle 65. The lifting motor 64 is driven to one end of the lifting screw 62, and the adjusting handle 65 is driven to the other end of the lifting screw 62. Multiple lifting assemblies 60 are arranged around the support base 30, and each lifting assembly 60 is individually adjustable. The lifting motor 64 provides driving force for the lifting slide 63 to move the support base 30 vertically. The arrangement of multiple lifting assemblies 60 around the support base 30 ensures uniform force distribution on the support base 30 during height adjustment, improving the stability and accuracy of the device's adjustment. Furthermore, since each lifting assembly 60 is individually adjustable, each lifting assembly 60 can be replaced individually, reducing the maintenance cost of the device.

[0035] like Figure 1 , Figure 3 As shown, the movable base 20 is equipped with a movable motor 21 and a movable gear, and a rack 14 is provided in the extending direction of the ground rail assembly 10. The movable gear and the rack 14 mesh to drive the movable base 20 to move. The movable motor 21 provides power for the movable base 20 to move along the ground rail assembly 10, and at the same time drives the movable base 20 to move through the meshing of the movable gear and the rack 14, which greatly improves the stability and accuracy of the movable base 20 when moving along the ground rail assembly 10.

[0036] In this embodiment, a magnetic lock is provided on the movable base 20. When the movable base 20 is stationary, the magnetic lock is activated to lock the relative position of the movable base 20 and the ground rail assembly 10. When the welding robot 40 needs to weld at a specific position, the magnetic lock is activated to fix the movable base 20 in the current position, ensuring that the welding robot 40 is stable and stationary. After welding is completed, the magnetic lock is released, and the welding robot 40 can continue to move. Specifically, the magnetic lock also provides an additional locking function when the welding robot 40 moves, preventing the welding robot 40 from shifting its position due to vibration or accidental contact. The magnetic lock improves the stability of this movable welding equipment during the welding process and avoids welding quality problems caused by positional shifts.

[0037] like Figure 3As shown, the portable welding equipment also includes a magnetic base 71, located at the bottom of the welding robot 40. The welding robot 40 is detachably connected to the support base 30 via the magnetic base 71. The magnetic base 71 firmly adheres to the support base 30, ensuring the welding robot 40 remains stable during welding. The magnetic base 71 integrates a strong magnet, generating a powerful attraction force to fix the welding robot 40 to the support base 30. When the welding robot 40 needs to be replaced, the magnetic attachment can be released, facilitating quick installation and removal of the welding robot 40 from the support base 30.

[0038] like Figure 1 and Figure 5 As shown, the ground rail assembly 10 includes multiple interlocking rails 11, which can be straight or curved. In two adjacent rails 11, one rail 11 has a positioning pin, and the other rail 11 has a positioning hole 12, with the positioning pin inserted into the positioning hole 12. The ground rail assembly 10 also includes a horizontal clamping elbow 13, which connects the two adjacent rails 11. The ground rail assembly 10, with its multiple interlocking rails 11, can be assembled into straight or curved shapes according to actual needs to adapt to different welding paths. The interlocking design improves the flexibility and adaptability of the ground rail assembly 10, meeting the requirements of different welding tasks. When assembling the rails 11, the positioning pins are first inserted into the positioning holes 12 for positioning, ensuring precise alignment between the rails 11. After positioning, the horizontal clamping elbow 13 locks each rail 11 in place, preventing loosening or misalignment during use and ensuring the stability of the rail connection. The combination of the positioning pin and positioning hole 12 for insertion positioning and the horizontal pressing elbow clamp 13 for locking ensures the accuracy and stability of the track 11 splicing, and improves the overall stability and reliability of the ground track assembly 10.

[0039] like Figure 2 As shown, the mobile welding equipment also includes multiple photoelectric sensors 72, which are installed at different positions on the ground rail assembly 10. The photoelectric sensors 72 are used to detect the position of the welding robot 40. By detecting reflective marks or specific patterns on the welding robot 40, the photoelectric sensors 72 provide real-time feedback on the position information of the welding robot 40. When the welding robot 40 reaches a preset position, the photoelectric sensors 72 send a signal to control the welding robot 40 to begin welding operations. The photoelectric sensors 72 improve the accuracy of the welding robot 40's positioning, ensuring precise and accurate welding operations.

[0040] like Figure 1As shown, the mobile welding equipment also includes a vision camera 73, which is mounted on the moving end effector of the welding robot 40. The vision camera 73 is used to capture weld information. By mounting the vision camera 73 on the moving end effector of the welding robot 40, the vision camera 73 can capture the three-dimensional information of the weld, helping the welding robot 40 to accurately identify the weld position and shape, thereby adjusting the welding path and parameters of the welding robot 40 to ensure welding quality. The placement of the vision camera 73 improves the welding robot 40's ability to identify welds, enabling it to adapt to welds of different shapes and positions, thus improving the adaptability and quality of welding.

[0041] In this embodiment, the mobile welding equipment also includes a control cabinet 74, an electrical cabinet 75, and a welding machine 76. The control cabinet 74 and electrical cabinet 75 are fixedly installed, while the welding machine 76 is mounted on the mobile base 20. The welding machine 76, electrical cabinet 75, and welding robot 40 are all electrically connected to the control cabinet 74. By integrating the electrical signals of the welding machine 76, electrical cabinet 75, and welding robot 40 through the control cabinet 74, centralized control and management of the welding operation can be achieved, making the control of the welding operation more convenient and improving the intelligence level and production efficiency of the welding operation.
