[0026] like Figures 1 to 3As shown, the welding positioner for the fuel filling pipe includes a base 1 and at least one limiting assembly 2. A limiting groove 3 is provided on the base 1. The limiting groove 3 runs from the first side of the base 1 to the second side of the base 1. The second side is the opposite side of the first side. The limiting groove 3 is used to accommodate the filling pipe 5. Both ends of the limiting assembly 2 span the limiting groove 3 and are connected to the base 1. The limiting assembly 2 can be opened and closed. The limiting assembly 2 is used to fix the filling pipe 5 in the limiting groove 3.

[0027] The limiting groove 3 of this embodiment runs from the first side of the base 1 to the second side of the base 1, and the second side is the opposite side of the first side. This arrangement facilitates placing the connecting end of the filling pipe 5 in the limiting groove 3, and can ensure that the two sections of the filling pipe 3 to be connected have good alignment and parallelism. In addition, the limiting assembly 2 of this embodiment can be opened and closed, which is convenient for placing and removing the connecting end of the filling pipe 5.

[0028] The welding positioner for the fuel filling pipe provided in this embodiment includes a base 1 and at least one limiting assembly 2. A limiting groove 3 is provided on the base 1. The limiting groove 3 is used to accommodate the filling pipe 5. The two ends of the limiting assembly 2 span the limiting groove 3 and are connected to the base 1. The limiting assembly 2 can be opened and closed. The limiting assembly 2 is used to fix the filling pipe 5 in the limiting groove 3. When in use, first place the welding positioner of this scheme, then open the limiting assembly 2, place the connecting ends of the two sections of the filling pipe 5 to be connected in the limiting groove 3, and adjust the distance between the two sections of the filling pipe 5, then close the limiting assembly 2, use the limiting assembly 2 to fix the filling pipe 5 in the limiting groove 3, and expose the connection between the two sections of the filling pipe 5, and finally perform welding between the two sections of the filling pipe 5. Using the welding positioner of this scheme, the alignment and horizontality between the two adjacent sections of the filling pipe 5 can be guaranteed, and the width of the weld 6 is convenient to adjust. It is easy to use, simple in structure, and can effectively improve the welding efficiency.

[0029] In some embodiments, Figure 1 and Figure 3 As shown, the base 1 includes a first support plate 11 and a second support plate 12 connected to each other. There is an angle between the first support plate 11 and the second support plate 12 to form a limiting groove 3. In this embodiment, the limiting groove 3 is formed by the angle between the first support plate 11 and the second support plate 12, so the cross section of the limiting groove 3 is triangular, which can be suitable for accommodating and fixing filling pipes 5 of different diameters. The limiting groove 3 with a triangular cross section can have a larger range of use and a better limiting effect.

[0030] It should be noted that the first support plate 11 and the second support plate 12 of the present embodiment may be connected by welding, or the first support plate 11 and the second support plate 12 may be provided as an integrally formed structure.

[0031] In some embodiments, Figure 2 and Figure 3 As shown, the base 1 also includes a support leg 4. The support leg 4 is supported at the bottom of the first support plate 11 and the second support plate 12. In this embodiment, the support leg 4 is arranged at the bottom of the first support plate 11 and the second support plate 12, so that the base 1 can be stably placed on the operating platform, which is convenient for fixing and limiting the filling pipe 5. It can be understood that the support leg 4 and the first support plate 11 and the second support plate 12 can be connected by welding, clamping, etc., and this embodiment does not impose too many restrictions on this, as long as a stable connection between the support leg 4 and the base 1 can be achieved.

[0032] In some embodiments, Figure 1 and Figure 3 As shown, the limiting assembly 2 includes: a first flexible fixing belt 21 and a second flexible fixing belt 22. The ends of the first flexible fixing belt 21 and the second flexible fixing belt 22 are hinged on the base 1 and symmetrically arranged on both sides of the width direction of the limiting groove 3. The free ends of the first flexible fixing belt 21 and the second flexible fixing belt 22 are detachably connected together through a connecting piece to fix the filling pipe 5 in the limiting groove 3. In this embodiment, the filling pipe 5 is fixed in the limiting groove 3 by the cooperation of the first flexible fixing belt 21, the second flexible fixing belt 22 and the connecting piece. Since the first flexible fixing belt 21 and the second flexible fixing belt 22 are flexible, they can fit more closely with the outer wall of the filling pipe 5, so that the fixing of the filling pipe 5 can be more firmly and reliably, and the displacement of the filling pipe 5 during the welding process can be avoided. In addition, the first flexible fixing belt 21 and the second flexible fixing belt 22 are flexible, which can avoid the outer wall of the filling pipe 5 from being strangled.

[0033] In some embodiments, Figures 1 to 3As shown, the connecting piece includes a nut 23 and an adjusting screw 24. The free end of the first flexible fixing belt 21 is hinged on the nut 23. The free end of the second flexible fixing belt 22 is detachably connected to the nut 23. The adjusting screw 24 is connected to the nut 23 by threaded fit. The bottom end of the adjusting screw 24 can abut against the side of the filling pipe 5. The connecting piece of this embodiment includes a nut 23 and an adjusting screw 24. When fixing the filling pipe 5, the free ends of the first flexible fixing belt 21 and the second flexible fixing belt 22 are connected to the nut 23, and the adjusting screw 24 is screwed into the nut 23 so that the bottom end of the adjusting screw 24 abuts against the side wall of the filling pipe 5, and the first flexible fixing belt 21 and the second flexible fixing belt 22 are tightened, thereby further improving the fixing stability of the filling pipe 5. In addition, the cooperation between the nut 23 and the adjusting bolt 24 can improve the applicable range of the first flexible fixing belt 21 and the second flexible fixing belt 22. When the diameter of the filling pipe 5 is small, the first flexible fixing belt 21 and the second flexible fixing belt 22 can be tightened by increasing the depth of the adjusting screw 24 screwed into the nut 23 and increasing the distance between the nut 23 and the filling pipe 5, thereby effectively fixing the filling pipe 5.

[0034] In some embodiments, Figures 1 to 3 As shown, the first flexible fixing belt 21 and the second flexible fixing belt 22 are both chain structures. The chain structure includes a plurality of unit sections, and two adjacent unit sections are hinged to each other through a connecting shaft. The first flexible fixing belt 21 and the second flexible fixing belt 22 of this embodiment are both chain structures, including a plurality of unit sections hinged through a connecting shaft. When used for welding filling pipes 5 of different diameters, the length of the first flexible fixing belt 21 and the second flexible fixing belt 22 can be adjusted by simply increasing or decreasing the number of unit sections, thereby ensuring the degree of fit between the first flexible fixing belt 21 and the second flexible fixing belt 22 and the outer wall of the filling pipe 5, and ensuring that the fixing of the filling pipe 5 is effective.

[0035] In some embodiments, Figures 1 to 3 As shown, there are two limit assemblies 2. The two limit assemblies 2 are arranged in sequence along the length direction of the limit groove 3. Each limit assembly 2 is used to fix a filling pipe 5. Since the welding positioner of this embodiment is used to assist the welding between two adjacent sections of the filling pipe 5, two limit assemblies 2 are set, and each limit assembly 2 fixes a filling pipe. Such a setting ensures the alignment of the two sections of the filling pipe 5. However, it can be understood that in other embodiments, the number of limit assemblies 2 can also be multiple, and the specific number can be determined according to parameters such as the length and diameter of the filling pipe 5.

[0036] In some embodiments, Figure 3As shown, the base 1 includes an angle steel. The two sides of the angle steel have equal widths. The right-angle groove formed between the two sides of the angle steel is a limit groove 3. The base 1 of this embodiment uses angle steel, which is easy to obtain, has a stable structure, and can ensure the straightness of the limit groove 3, which is conducive to improving the alignment of the filling pipe 5 during welding, and is also conducive to reducing the manufacturing cost. In addition, the use of angle steel can have a better load-bearing effect, and the load-bearing capacity can reach more than 80kg.

[0037] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
