Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this utility model.

[0024] like Figure 1-5 As shown, this utility model provides a welding equipment for processing large-capacity, high-pressure gaseous hydrogen storage spherical tanks, including a body 100, an adjustment mechanism 101, a welding mechanism 102, and an auxiliary mechanism 103; the adjustment mechanism 101 includes a pair of mounting brackets 10101, which are respectively disposed on both sides of the body 100, and a pair of magnetic pull wheels 10102 are rotatably connected to the outer side of each pair of mounting brackets 10101; the auxiliary mechanism 103 includes a movable frame 10301, the bottom end of which is connected to... One side of the upper end face of the body 100 is connected to an extension frame 10303 fixedly installed on one side of the movable frame 10301. A movable block 10307 is slidably installed inside the extension frame 10303 on one side of the movable frame 10301. A slide rail 10308 is fixedly installed on one side of the movable block 10307. A clamp 10306 is slidably installed on one side of the slide rail 10308. The welding mechanism 102 includes a laser welding head 10201, which is located inside the clamp 10306.

[0025] The main structure and function of the welding equipment for processing large-capacity, high-pressure gaseous hydrogen storage spherical tanks are as follows: The main body 100 provides a supporting foundation for the entire welding equipment. The adjusting mechanism 101 adjusts the position of the moving welding equipment. The welding mechanism 102 performs the welding operation on the spherical tank. The auxiliary mechanism 103 controls and adjusts the position of the welding mechanism 102.

[0026] The welding process for a spherical tank using welding equipment is as follows: During operation, the magnetic rollers 10102 on the mounting brackets 10101 located on both sides of the machine body 100 can adhere to the surface of the spherical tank, facilitating movement and positioning on the tank. Simultaneously, the angle of the mounting brackets 10101 can be adjusted according to the curvature of the spherical tank surface, allowing the magnetic rollers 10102 to fit more closely to the tank surface. When welding is required, the welding equipment can be moved to the desired welding location on the spherical tank by manipulating the adjustment mechanism 101, and then the auxiliary mechanism 103 cooperates with the welding mechanism 102 to perform the welding work. The movable frame 10301 of the auxiliary mechanism 103 is mounted on the machine body 100, the movable block 10307 can slide within the extension frame 10303, and the cooperation of the slide rail 10308 and the clamp 10306 adjusts the position of the welding mechanism 102, ensuring that the laser welding head 10201 is aligned with the welding position for accurate welding.

[0027] The large-capacity, high-pressure gaseous hydrogen storage spherical tank provided by this utility model allows the magnetic roller 10102 to better fit the surface of the spherical tank by adjusting the angle of the mounting frame 10101, thus improving the stability of the body 100 moving on the surface of the spherical tank. The position of the welding mechanism 102 (laser welding head 10201) can be adjusted through the coordinated arrangement of the moving frame 10301, moving block 10307, ​​slide rail 10308, and clamp 10306. This allows the laser welding head 10201 to be controlled to move left, right, up, and down when welding seams, improving the welding effect. The entire welding process requires no manual welding operation, making it convenient, fast, and highly safe.

[0028] like Figure 4 As shown, the adjustment mechanism 101 further includes two pairs of rotating shafts 10105, which are rotatably inserted into both ends of the machine body 100. The opposite ends of each pair of rotating shafts 10105 extend through the machine body 100 to the outside and are connected to the inner side of the adjacent mounting bracket 10101. Furthermore, dual-axis motors 10104 are fixedly installed on both sides of the bottom end of the machine body 100, and the output ends of one pair of dual-axis motors 10104 are respectively connected to the two pairs of rotating shafts 10105 for transmission.

[0029] The rotating shaft 10105 of the adjustment mechanism 101 is rotatably inserted into both ends of the machine body 100 and connected to the inner side of the mounting frame 10101, so that the mounting frame 10101 can rotate around the rotating shaft 10105. The angle of the mounting frame 10101 can be adjusted according to the curved shape of the spherical tank, thereby enhancing the fit between the equipment and the surface of the spherical tank and improving the stability of the equipment's movement on the spherical tank.

[0030] The dual-axis motors 10104 on both sides of the bottom inside the machine body 100 are connected to the rotating shaft 10105. The dual-axis motors 10104 can drive the rotating shaft 10105 to rotate, which in turn drives the mounting frame 10101 to rotate, so as to realize the flexible adjustment of the overall angle of the equipment to adapt to the welding requirements of spherical tanks of different specifications.

[0031] like Figure 2 As shown, further, a first servo motor 10103 is fixedly installed on the inner side of each of the pair of mounting brackets 10101, and the output end of the pair of first servo motors 10103 is respectively connected to one of the magnetic chucks 10102.

[0032] The first servo motor 10103 inside the mounting bracket 10101 is connected to the magnetic chuck 10102. The first servo motor 10103 can control the rotation of the magnetic chuck 10102, enabling the equipment to move on the surface of the spherical tank and improve welding efficiency.

[0033] like Figure 2 and Figure 3 As shown, further, a screw 10310 is rotatably connected inside the movable frame 10301, and a slider 10311 is threadedly connected to the screw 10310. One side of the slider 10311 is fixedly connected to the movable block 10307. Further, a second servo motor 10302 is fixedly mounted at one end of the movable frame 10301, and the output end of the second servo motor 10302 is drively connected to the screw 10310. Further, a telescopic rod 10309 is inserted into one side of the upper end of the slide rail 10308, and the bottom end of the telescopic rod 10309 is fixedly connected to one side of the upper end of the clamp 10306.

[0034] The screw 10310 inside the movable frame 10301 is threadedly connected to the slider 10311, and the slider 10311 is fixedly connected to the movable block 10307. The rotation of the screw 10310 can drive the slider 10311 and the movable block 10307 to move within the extension frame 10303, thereby adjusting the horizontal position of the laser welding head 10201.

[0035] The second servo motor 10302 at one end of the moving frame 10301 is connected to the screw 10310 for transmission. The second servo motor 10302 can control the rotation of the screw 10310, thereby controlling the moving speed and position of the moving block 10307, ​​improving the accuracy and stability of the horizontal position adjustment of the laser welding head 10201.

[0036] The telescopic rod 10309 on the slide rail 10308 is connected to the clamp 10306. By controlling the extension and retraction of the telescopic rod 10309, the vertical height of the clamp 10306 and the laser welding head 10201 can be adjusted, so that the laser welding head 10201 can better adapt to the undulations of the spherical tank surface and the height changes of the welding position.

[0037] like Figure 2 and Figure 3 As shown, a laser vision sensor 10305 is further embedded at the bottom of the extension frame 10303, and a camera 10304 is fixedly installed at one end of the extension frame 10303. Furthermore, the welding mechanism 102 also includes a fiber laser 10202, the bottom of which is connected to one side of the upper end of the body 100, and the emitting end of the fiber laser 10202 is connected to one end of the laser welding head 10201 via an optical fiber.

[0038] The laser vision sensor 10305 at the bottom of the extension frame 10303 can detect the shape, position, and surface condition of the welding area of ​​the spherical tank in real time, providing a basis for adjusting the welding parameters. The camera 10304 at one end of the extension frame 10303 can monitor the welding process in real time, allowing users to view the weld condition and observe the welding status when the equipment is retracted.

[0039] The fiber laser 10202 of the welding mechanism 102 is mounted on the body 100 and connected to the laser welding head 10201 via fiber optic cable. The fiber laser 10202 can generate a high-energy laser beam, which is transmitted to the laser welding head 10201 via fiber optic cable for welding, thus meeting the welding requirements of large-capacity high-pressure gaseous hydrogen storage spherical tanks.

[0040] The following is the complete working principle of the welding equipment for processing large-capacity, high-pressure gaseous hydrogen storage spherical tanks provided by this utility model: The machine body 100 serves as the foundation supporting the entire equipment. The adjustment mechanism 101 begins operation: the dual-axis motors 10104 on both sides of the bottom inside the machine body 100 are started, and their output ends drive the rotating shaft 10105 connected to them to rotate, thereby causing the mounting frame 10101 to rotate around the rotating shaft 10105, adjusting the angle according to the curved shape of the spherical tank, enhancing the fit between the equipment and the surface of the spherical tank, and improving the stability of movement. At the same time, the first servo motor 10103 inside the mounting frame 10101 drives the magnetic chuck 10102 to rotate, so that the equipment is attracted to the surface of the spherical tank by the magnetic chuck 10102 and can move along a predetermined path. Next, the second servo motor 10302 at one end of the moving frame 10301 is activated. Its output drives the screw 10310 to rotate. The slider 10311 on the screw 10310 drives the moving block 10307 to slide within the extension frame 10303, thereby adjusting the horizontal position of the laser welding head 10201. Furthermore, the telescopic rod 10309 on the slide rail 10308 adjusts the vertical height of the clamp 10306 and the laser welding head 10201 through telescopic adjustment, allowing the laser welding head 10201 to better adapt to the undulations of the spherical tank surface. Simultaneously, the laser vision sensor 10305 at the bottom of the extension frame 10303 detects the shape, position, and surface condition of the welding area of ​​the spherical tank in real time, providing a basis for adjusting welding parameters. The camera 10304 at one end of the extension frame 10303 monitors the welding process in real time. Finally, the welding mechanism 102 operates, and the fiber laser 10202 installed on the body 100 generates a high-energy laser beam, which is transmitted through the fiber optic line to the laser welding head 10201 located in the clamp 10306 to perform welding operations on the spherical tank.
