[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an online welding grounding conductive device, comprising a workbench 1, a fixing frame 15 is fixedly connected to the top of the workbench 1, a vertical plate 6 is fixedly connected to the rear side of the top of the fixing frame 15, a driving motor 13 is fixedly connected to the rear side of the vertical plate 6, an output end of the driving motor 13 passes through the vertical plate 6 and is fixedly connected to a worm 12, a worm wheel 11 is meshedly connected to the right side of the worm 12, a hollow tube 9 is fixedly connected to the bottom of the worm wheel 11, an arc rod 8 is threadedly connected to the inner side of the hollow tube 9, a mounting ring 7 is fixedly connected to the left end of the arc rod 8, and a buffer mechanism 2 is installed at the middle of the top of the workbench 1; a slip ring 10 is fixedly connected to the bottom of the outer wall of the worm wheel 11, a ring groove 14 is provided on the top of the fixing frame 15, and the slip ring 10 is slidably connected to the ring groove 14;

[0030] Specifically, during the welding process, installing the welding gun in the mounting ring 7 is a very critical step. In order to ensure the stability and accuracy of the welding gun, a special drive system is required to adjust the angle of the welding gun. This drive system is composed of a drive motor 13, a worm 12, a worm wheel 11 and a slip ring 10. When the drive motor 13 is started, it drives the worm 12 to rotate, and the rotation of the worm 12 is meshed with the worm wheel 11, thereby driving the worm wheel 11 to rotate half a circle. This drive method has high precision and stability, because the rotation angle of the worm wheel 11 can be accurately controlled by the rotation of the worm 12. At the same time, the model of the drive motor 13 can adopt a reciprocating motor. This motor has the characteristics of high torque and low inertia, which can ensure the rapid response and precise control of the drive system. While the worm wheel 11 rotates, the hollow tube 9, the arc rod 8 and the mounting ring 7 will also adjust their angles accordingly. This adjustment method allows the angle of the welding gun to be flexibly adjusted to meet different welding requirements. The sliding of the slip ring 10 in the ring groove 14 is used for limiting the rotation of the worm gear 11. At the same time, the rotation trajectory of the worm gear 11 is planned, so that the welding efficiency and quality can be improved while ensuring the stability of the welding gun. The threaded design on the arc rod 8 allows the arc rod 8 to be easily disassembled and replaced, which makes it possible to quickly replace mounting rings 7 of different sizes according to different welding requirements, thereby adapting to the installation of various types of welding heads. This drive system achieves flexible adjustment of the welding gun angle by precisely controlling the rotation angle of the worm gear 11. At the same time, the limiting design of the slip ring 10 and the threaded design of the arc rod 8 make the entire system highly stable and adaptable. This design not only improves the welding efficiency and quality, but also provides convenience for the installation of welding heads of different types, thereby improving the functionality of the equipment.

[0031] Reference Figure 1 and Figure 3 The buffer mechanism 2 includes a rubber plate 204, which is installed in the middle of the top wall of the workbench 1. Hollow columns 201 are installed at the four corners of the top of the rubber plate 204. The inner bottom wall of the hollow column 201 is fixedly connected with a spring 202, and the top of the spring 202 is fixedly connected with a slide bar 203, and the top of the slide bar 203 is fixedly connected with a placement plate 205; the left and right sides of the top of the placement plate 205 are installed with a clamp assembly 5; the left and right sides of the inner wall of the hollow column 201 are provided with a slide groove 16, and the left and right sides of the slide bar 203 are fixedly connected with a slider 17, and the slider 17 is slidably connected with the corresponding slide groove 16 respectively;

[0032] Specifically, when welding the workpiece, it is necessary to ensure that the placement position and fixing method of the workpiece can ensure its stability and accuracy. For this purpose, two sets of clamp assemblies 5 are used to place the workpiece in the middle position, and the workpiece is clamped and fixed by the clamp assemblies 5. This clamping method can effectively prevent the workpiece from moving or deforming during the welding process, thereby ensuring the accuracy and quality of welding. At the same time, the placement plate 205 is used to bear the force on the workpiece. The placement plate 205 has sufficient rigidity and stability, and can effectively disperse the gravity of the workpiece and the impact force during welding, thereby avoiding uneven force or deformation of the workpiece during the welding process. During the welding process, due to the impact force, the placement plate 205 will press down the slide bar 203, so that the spring 202 drives the slide bar 203 The design is retracted, which can effectively absorb the impact force and reduce the vibration and deformation of the workpiece during the welding process. The slider 17 slides in the slide groove 16 and is used for limiting the movement of the slide bar 203. This design can ensure the stability and accuracy of the slide bar 203 during the movement, and avoid excessive movement or deviation of the slide bar 203. In addition, the movement trajectory of the slide bar 203 is also planned to ensure its accuracy and stability during the welding process. At the same time, the impact force is transmitted to the rubber plate 204 through the hollow column 201, and the impact force is distributed by the rubber plate 204, thereby performing buffering. This design can effectively reduce the impact of the impact force on the workpiece, avoid the situation where the workpiece has a decrease in accuracy during welding, and improve the welding quality and efficiency.

[0033] Reference Figure 1 The bottom of the workbench 1 is fixedly connected with a bracket 3, and the end of the bracket 3 is fixedly connected with a bottom pad 4; the bottom of the bottom pad 4 is made of non-slip material; the two clamp components 5 are symmetrically designed;

[0034] Specifically, the equipment is supported by the bracket 3, the stability during support is increased by the base pad 4, the grip during support is increased by the base pad 4 made of anti-slip material, and the workpiece can be stably positioned by the symmetrically designed clamp assembly 5.

[0035] Working principle: install the welding gun in the mounting ring 7, turn on the driving motor 13 to drive the worm 12 to rotate, and the rotation of the worm 12 is meshed with the worm wheel 11 to drive the worm wheel 11 to rotate half a circle. The driving motor 13 can be a reciprocating motor. The rotation of the worm wheel 11 can adjust the angle of the hollow tube 9, the arc rod 8 and the mounting ring 7. When the worm wheel 11 rotates, the slip ring 10 is driven to slide in the ring groove 14, which is used for limiting the rotation of the worm wheel 11. At the same time, the rotation trajectory of the worm wheel 11 is planned. The angle of the welding head in the mounting ring 7 is adjusted through the adjustment of the angle. The arc rod 8 can be disassembled later through the thread on the arc rod 8 to replace the size of the mounting ring 7, so as to adapt to the installation of various types of welding heads, providing The functionality of the equipment is improved to meet the needs of use, and the workpiece is placed in the middle position of the two sets of clamp assemblies 5, and the workpiece is clamped and fixed by the clamp assemblies 5, and the plate 205 is placed to bear the force of the workpiece. When welding, the plate 205 is placed to bear the force and the impact force presses down the slide bar 203 to make the spring 202 drive the slide bar 203 to retract, and when the slide bar 203 moves, the slider 17 is driven to slide in the slide groove 16, which is used for the limiting work when the slide bar 203 moves, and the moving trajectory of the slide bar 203 is planned. At the same time, the impact force is transmitted to the rubber plate 204 through the hollow column 201, and the impact force is distributed by the rubber plate 204, thereby performing buffering work, avoiding the situation where the accuracy of the workpiece decreases during welding, and bringing convenience to subsequent processing.
