Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1

[0018] Reference Figure 1 、 2, which is the first embodiment of the present utility model. This embodiment provides a welding device for a structural steel claw, including a connecting seat 1. One end of the connecting seat 1 is fixedly connected to a support plate 2. The support plate 2 is fixedly connected to a rotating shaft 9. The rotating shaft 9 is rotatably connected to one side of a cylindrical housing 3. A plurality of steel claws 4 are slidably connected to the other end of the cylindrical housing 3. The steel claws 4 are respectively hinged to a clamping component 5. The clamping component 5 is sleeved on a threaded rod 6 through a threaded structure. The threaded rod 6 is rotatably sleeved on a support cylinder 7. One end of the support cylinder 7 is fixedly connected to the cylindrical housing 3, and the other end is slidably sleeved on the clamping component 5. The end of the threaded rod 6 is fixedly connected to a servo motor 8, and the servo motor 8 is fixedly installed inside the cylindrical housing 3.

[0019] According to the outer diameter size of the welding workpiece, start the servo motor 8 to work. The servo motor 8 drives the threaded rod 6 to rotate. The threaded rod 6 drives the clamping component 5 to work. The clamping component 5 drives the steel claws 4 to change the clamping size. After the steel claws 4 clamp the end of the workpiece, the servo motor 8 stops. Thus, it is convenient for the welding device to perform vertical welding operations on the cylindrical workpiece. When the angle needs to be adjusted, the driving motor 10 works,带动固接的蜗杆11转动,蜗杆11配合啮合连接的蜗轮12,带动柱形壳体3以转轴9为圆心改变角度,柱形壳体3进而带动钢爪4夹持的工件改变角度,方便工件焊接时的不同焊接角度,增大了本实用新型的适用广泛性。

[0020] Embodiment 2

[0021] Refer to Figure 1-3 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. Specifically, the support plate 2 is in a U-shaped structure, and the U-shaped structure provides a rotation space for the angle adjustment of the cylindrical housing 3.

[0022] Specifically, a worm gear 12 is fixedly sleeved in the middle of the rotating shaft 9. One side of the worm gear 12 is meshed with a worm 11. One end of the worm 11 is fixedly connected to the output shaft of the driving motor 10, and the driving motor 10 is fixedly installed inside the cylindrical housing 3.

[0023] The driving motor 10 works,带动固接的蜗杆11转动,蜗杆11配合啮合连接的蜗轮12,带动柱形壳体3以转轴9为圆心改变角度,柱形壳体3进而带动钢爪4夹持的工件改变角度,方便工件焊接时的不同焊接角度,增大了本实用新型的适用广泛性。

[0024] Specifically, a plurality of sliding openings 31 are formed on one end face of the cylindrical housing 3. There are four sliding openings 31 evenly distributed in a circumferential manner. One end of the steel claw 4 is fixedly connected to a slider 41. The slider 41 is slidably connected to the sliding opening 31. One end of the slider 41 away from the steel claw 4 is fixedly connected to a limiting block 42, and the limiting block 42 is movably arranged inside the cylindrical housing 3.

[0025] It should be noted that there are some unclear parts in the original text, such as the incorrect expression "带动固接的蜗杆11转动" which should be corrected for a more accurate translation. The above translation is based on the existing text as much as possible.When the steel claw 4 moves, the slider 41 moves in the sliding opening 31 to change the distance between the steel claw 4 and the center of the cylindrical shell 3, thereby facilitating the operation of workpieces with different outer diameters.

[0026] Specifically, the clamping assembly 5 includes a movable cylinder 51, an articulated seat 52, a connecting rod 53, and an articulated groove 54. The movable cylinder 51 is slidably sleeved on the outside of the support cylinder 7 and one end of the movable cylinder 51 is sleeved on the threaded rod 6 through a threaded structure. Several articulated seats 52 are fixedly connected on both sides of the outer wall of the movable cylinder 51. The articulated seat 52 is hinged to one end of the connecting rod 53, and the other end of the connecting rod 53 is hinged to the articulated groove 54. The articulated groove 54 is opened on one side of the steel claw 4.

[0027] Furthermore, articulated seats 52 are evenly spaced around the circumference, connecting rods 53 are arranged parallel to each other, and one end of threaded rod 6 is fixedly connected to anti-slip disc 61. Depending on the outer diameter of the workpiece being welded, servo motor 8 is activated, which drives threaded rod 6 to rotate, which in turn drives clamping assembly 5 to operate, causing movable cylinder 51 of clamping assembly 5 to move. Movable cylinder 51 cooperates with connecting rod 53 to drive steel claw 4 to change the clamping size.

[0028] Example 3

[0029] Reference Figure 1-3 , which is the third embodiment of the present utility model, and is based on the above two embodiments. When in use, according to the outer diameter of the welding workpiece, the servo motor 8 is started to work, the servo motor 8 drives the threaded rod 6 to rotate, and the threaded rod 6 drives the clamping assembly 5 to work, and the movable cylinder 51 of the clamping assembly 5 moves, and the movable cylinder 51 cooperates with the connecting rod 53 to drive the steel claw 4 to change the clamping size. After the steel claw 4 completes clamping of the workpiece end, the servo motor 8 stops, thereby facilitating the vertical welding operation of the cylindrical workpiece by the welding device. When the angle needs to be adjusted, the drive motor 10 is operated to drive the fixed worm 11 to rotate, and the worm 11 cooperates with the meshing worm gear 12 to drive the cylindrical shell 3 to change the angle with the rotating shaft 9 as the center of the circle. The cylindrical shell 3 then drives the workpiece clamped by the steel claw 4 to change the angle, which is convenient for different welding angles during workpiece welding, thereby increasing the applicability of the present utility model.
