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.

[0027] Example 1: As Figures 2-6 As shown, the present invention provides an all-position intelligent welding machine, including a worktable 1, a movable welding component 2 fixedly installed on the top of the worktable 1, a mounting base 3 fixedly installed on the side of the worktable 1 near the movable welding component 2, a slide rail 4 fixedly installed on the outer surface of the mounting base 3, a movable motor 5 located on the top of the worktable 1 fixedly installed on the outer surface of the slide rail 4, a bidirectional lead screw 6 fixedly installed on the output shaft of the movable motor 5, a limit component 7 threadedly connected to the outer surface of the bidirectional lead screw 6, and a weldment body 8 provided on the outer surface of the limit component 7.

[0028] Specifically, the limiting component 7 and the slide rail 4 are slidably connected. Two identical limiting components 7 are provided, symmetrically distributed about the center line of the bidirectional lead screw 6. This allows the weldment body 8 to be placed in approximately corresponding positions between the two limiting components 7. Next, the moving motor 5 is started, driving the bidirectional lead screw 6 to rotate. Since the limiting component 7 and the bidirectional lead screw 6 are threadedly connected and slidably connected to the slide rail 4, the two limiting components 7 will move towards or away from each other along the slide rail 4 as the bidirectional lead screw 6 rotates. The distance between the two limiting components 7 is adjusted according to the size of the weldment body 8 to limit and fix the weldment body 8, preventing positional displacement of the weldment body 8 due to unilateral force.

[0029] Specifically, the mobile welding assembly 2 includes a fixed base 201, a connecting belt 202 on the outer surface of the fixed base 201, a fixed frame 203 slidably connected to the outer surface of the fixed base 201, a drive motor 204 fixedly mounted on the outer surface of the fixed frame 203, a gear 205 fixedly mounted on the output shaft of the drive motor 204, and a gear 206 rotatably mounted on the outer surface of the fixed frame 203. The gear 205 and the gear 206 are meshed. The advantage is that the sliding connection between the fixed base 201 and the fixed frame 203, combined with the gear transmission, makes the entire movement process smooth and stable, reduces welding deviations caused by unstable movement, and improves the stability and quality of welding. At the same time, the connecting belt 202 also prevents the cables from being messy and affecting the welding operation and equipment operation safety.

[0030] Specifically, a connecting block 207 and a connecting frame 208 are fixedly installed on the outer surface of gear 206. A servo motor 1 209 is fixedly installed on the outer surface of the connecting frame 208. A connecting column 210 is fixedly installed on the output shaft of servo motor 1 209. A servo motor 211 and a servo motor 3 212 are provided on the outer surface of the connecting column 210. A welding head 213 is fixedly installed on the output shaft of servo motor 3 212. The advantage is that the coordinated action of multiple servo motors can achieve precise control of the welding head 213 in multiple dimensions, enabling it to adapt to the requirements of various complex shapes of the welded object body 8 and different welding paths. Whether it is planar welding or spatial three-dimensional welding, the welding point can be accurately positioned, which greatly improves the flexibility and adaptability of welding, makes the weld more uniform and beautiful, the welding strength more in line with requirements, reduces welding defects, and improves the overall quality of the welded product.

[0031] Example 2: ​ As shown, this is an improvement on the previous embodiment.

[0032] Specifically, the limiting component 7 includes a movable base 701, an mounting plate 702 fixedly mounted on the outer surface of the movable base 701, a slot 703 formed on the outer surface of the mounting plate 702, a limiting seat 704 provided on the outer surface of the mounting plate 702, and an insert rod 705 fixedly mounted on the outer surface of the limiting seat 704. The insert rod 705 and the slot 703 are plugged into each other. The advantage is that, through the cooperation of the slot 703 and the insert rod 705, the accuracy and stability of the limiting seat 704 on the mounting plate 702 can be guaranteed. It will not easily loosen or shift during the welding process, ensuring a reliable limiting effect on the welded object body 8, which is conducive to the smooth progress of the welding operation. At the same time, the components above the limiting seat 704 can be adjusted according to the shape of the workpiece, thereby facilitating the limiting of different workpieces.

[0033] Specifically, the outer surface of the limiting seat 704 is provided with a sliding groove 706 and multiple equally spaced slots 707. A limiting clamp 708 is provided on the outer surface of the limiting seat 704. An extension seat 709 and a slider 710 are fixedly installed on the outer surface of the limiting clamp 708. The slider 710 is slidably connected to the sliding groove 706. The advantage is that the sliding connection between the slider 710 and the sliding groove 706 allows the limiting clamp 708 to flexibly adjust its position to adapt to different sizes and shapes of the weldment body 8. It can accurately clamp and limit the weldment, ensuring that the weldment will not be displaced during the welding process.

[0034] Specifically, a limiting groove 711 is provided on the outer surface of the limiting clamp 708. The limiting clamp 708 is adapted to the welding body 8. The advantage is that when using the limiting clamp 708 to clamp the welding body 8, the welding body 8 is placed into the limiting groove 711 of the limiting clamp 708, so that the welding body 8 and the limiting groove 711 fit tightly. The limiting groove 711 precisely limits the shape and position of the welding body 8.

[0035] Working principle: When in use, place the welded object body 8 in a roughly corresponding position between the two limiting components 7. Next, the moving motor 5 is started, driving the bidirectional lead screw 6 to rotate. Since the limiting component 7 is threadedly connected to the bidirectional lead screw 6 and slidably connected to the slide rail 4, when the bidirectional lead screw 6 rotates, the two limiting components 7 will move towards or away from each other along the slide rail 4. According to the size of the welded object body 8, the distance between the two limiting components 7 is adjusted so that the welded object body 8 can be limited and fixed, which can avoid the position displacement of the welded object body 8 due to unilateral force. The sliding connection between the fixed seat 201 and the fixed frame 203, combined with gear transmission, makes the entire movement process smooth and stable, reducing welding deviation caused by unstable movement, and improving the stability and quality of welding. At the same time, the connecting strap 202 organizes the cables and avoids the welding operation and equipment operation safety affected by messy cables. The coordinated action of multiple servo motors can achieve precise control of the welding head 213 in multiple dimensions, making it adaptable to the requirements of various complex shapes of welded object bodies 8 and different welding paths. Whether it is planar welding or spatial three-dimensional welding, the welding point can be accurately positioned, which greatly improves the flexibility of welding. The adaptability allows for more uniform and aesthetically pleasing welds, ensuring weld strength meets requirements, reducing welding defects, and improving the overall quality of the welded product. The cooperation between the slot 703 and the insert rod 705 guarantees the accuracy and stability of the limit seat 704's installation on the mounting plate 702, preventing easy loosening or displacement during welding. This ensures reliable limiting of the welded object 8, facilitating smooth welding operations. Furthermore, the components above the limit seat 704 can be adjusted according to the shape of the workpiece, facilitating the limiting of different workpieces. The sliding connection between the slider 710 and the groove 706 allows the limiting clamp 708 to flexibly adjust its position to adapt to different sizes and shapes of the welded object body 8. It can accurately clamp and limit the welded object, ensuring that the welded object will not shift during the welding process. When using the limiting clamp 708 to clamp the welded object body 8, the welded object body 8 is placed into the limiting groove 711 of the limiting clamp 708, so that the welded object body 8 and the limiting groove 711 fit tightly together. The limiting groove 711 precisely limits the shape and position of the welded object body 8.
