[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 、 Figure 3 and Figure 4, an embodiment provided by the present utility model: a gas meter welding joint correction device, including a base 1. The base 1 can support the whole device. There is a rotating connection with a bearing plate 2 at the upper middle part of the base 1. The lower end of the bearing plate 2 can be connected to a rotating device and can drive the bearing plate 2 to rotate half a circle for the joint welding of the gas meter, so that feeding and welding can be carried out simultaneously, increasing the working efficiency. A fixed rod 3 is fixedly connected to the left end side of the bearing plate 2. The fixed rod 3 can support the correction rod 10 so that it can rotate with the bearing plate 2. A fixed column 14 is fixedly connected inside the upper end of the fixed rod 3. The fixed column 14 can support the correction rod 10 so that it can only rotate relative to the fixed rod 3 within a fixed distance. Both ends of the fixed column 14 are elastically connected to the correction rod 10 through a first spring 11. The first spring 11 can pull to keep the correction rod 10 in a vertical state, facilitating feeding. The left part of the correction rod 10 is slidably connected to the outer parts of both ends of the fixed column 14 and the upper end of the fixed rod 3. The inner parts of the lower end of the correction rod 10 and both ends of the fixed column 14 are arc-shaped, so that the correction rod 10 can only rotate within a fixed distance. One end of the first spring 11 is fixedly connected to both ends of the fixed column 14, and the other end of the first spring 11 is fixedly connected to the left end inside the correction rod 10. The first spring 11 pulls the inner part of the lower end of the correction rod 10, so that the correction rod 10 can rotate upward for convenient welding.

[0032] Referring to Figure 1 , Figure 3 and Figure 4 , a clamping block 9 is elastically connected to the lower part of the fixed rod 3 through a second spring 12. The outer part of the clamping block 9 is slidably connected to the inner part of the lower end of the correction rod 10. The clamping block 9 can clamp the correction rod 10 to keep it in a horizontal state. One end of the second spring 12 is fixedly connected to the upper end inside the fixed rod 3, and the other end of the second spring 12 is fixedly connected to the lower part of the clamping block 9. The second spring 12 is kept squeezed by the fixed column 14 to fix the clamping block 9 inside the lower end of the correction rod 10. A positioning column 13 is slidably connected to the middle part of the clamping block 9. The positioning column 13 restricts the clamping block 9 to only slide vertically inside the fixed rod 3. The upper and lower parts of the positioning column 13 are fixedly connected to the upper end inside the fixed rod 3, and the fixed rod 3 keeps the positioning column 13 relatively fixed. A welding assembly is fixedly connected to the right part of the base 1. A clamping assembly is slidably connected to the upper end inside the bearing plate 2. The clamping assembly can quickly position and fix the gas meter. The clamping assembly includes a threaded rod 7. The threaded rod 7 can make the clamping block 8 slide horizontally to clamp and fix the gas meter. The outer part of the threaded rod 7 is threadedly connected to the clamping block 8. The clamping block 8 is L-shaped and can clamp the gas meter at the upper part. The outer part of the threaded rod 7 is rotatably connected to the upper end inside the bearing plate 2, and the outer part of the clamping block 8 is slidably connected to the upper end inside the bearing plate 2. The bearing plate 2 restricts the threaded rod 7 to only rotate horizontally, and the clamping block 8 keeps a vertical state.

[0033] Referring to Figure 1 - Figure 2, the welding assembly includes a welding device 5 which can slide down to weld and fix the upper docking head. The lower part of the welding device 5 is fixedly connected to the upper right part of the base 1. The base 1 can support and fix the welding device 5 to keep its position relatively fixed. The left part of the upper end of the welding device 5 is elastically connected to a pressing rod 4 through a third spring 6. The pressing rod 4 is L-shaped, and the right part of the upper end is T-shaped, so that the pressing rod 4 can only slide horizontally within a fixed distance relative to the welding device 5, which facilitates the rotation of the bearing plate 2 without obstruction. The lower part of the pressing rod 4 contacts the upper end of the clamping block 9. The lower part of the pressing rod 4 can be pressed to make the clamping block 9 slide down, so that the calibration rod 10 can automatically rotate to the vertical state without manual operation, which increases the simplicity of the operation. One end of the third spring 6 is fixedly connected to the front part of the upper end of the welding device 5. The third spring 6 can be pressed to prevent the pressing rod 4 from sliding back automatically. The other end of the third spring 6 is fixedly connected to the left part of the upper end of the pressing rod 4.

[0034] Working principle: Place the gas meter on the upper part of the bearing plate 2, and then rotate the threaded rod 7 so that the threaded rod 7 rotates and presses the clamping block 8 to slide towards the middle of the bearing plate 2, so that the clamping block 8 can clamp and fix the gas meter. Then, the joint can be placed on the upper part of the gas meter. Then, rotate the calibration rod 10 to the horizontal state until the lower part of the calibration rod 10 contacts the upper end of the joint, so that the joint is clamped and pressed to maintain the horizontal state and is fixed. At this time, the calibration rod 10 pulls the first spring 11, and the clamping block 9 slides up under the extrusion of the second spring 12 into the inside of the side end of the calibration rod 10 so that the calibration rod 10 will not slide back to its original position. Then, the bearing plate 2 can be driven to rotate through the rotating device. The bearing plate 2 can drive the clamping assembly to rotate. The clamping assembly can drive the gas meter to rotate half a circle, and the fixed rod 3 and the calibration rod 10 will rotate half a circle accordingly. Then, the welding device 5 slides down, so that the pressing rod 4 slides down. The pressing rod 4 presses the clamping block 9 to slide down. The clamping block 9 slides out of the inside of the calibration rod 10 and presses the second spring 12. At this time, the calibration rod 10 slides back to its original position under the pull of the first spring 11. At this time, the calibration rod 10 continues to slide down with the welding device 5 and is pressed backward by the clamping block 9 to press the third spring 6, so that the welding device 5 can weld the gas meter and the joint. After completion, the welding device 5 slides up and rotates the bearing plate 2. At this time, the fixed rod 3 presses to make the pressing rod 4 slide back and press the third spring 6. When the fixed rod 3 no longer contacts the pressing rod 4, the pressing rod 4 slides back to its original position under the extrusion of the third spring 6.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
