[0035] The liquid level gauge is a common component on the liquid storage tank. For example, the oil tank of the hydraulic transmission system on mechanical engineering equipment is equipped with a liquid level gauge. The liquid level gauge is used to monitor the liquid level in the oil tank so that the staff can know the storage amount of oil in the oil tank in time.

[0036] In the related art, the liquid level meter is installed on the liquid storage tank through a liquid level meter mounting plate. Specifically, the side wall of the liquid storage tank is provided with two through holes, and the liquid level meter mounting plate is provided with two mounting holes. When installing the liquid level meter, the liquid level meter mounting plate is welded to the outer wall of the liquid storage tank, and the mounting holes of the liquid level meter mounting plate are aligned with the corresponding through holes on the side wall of the liquid storage tank. Then, the mounting columns at both ends of the liquid level meter are respectively installed in the two mounting holes and penetrated through the two through holes. The liquid level meter is connected to the inner cavity of the liquid storage tank to realize the liquid level monitoring function.

[0037] However, when installing the liquid level meter, it was found that after the liquid level meter mounting plate was welded, the mounting holes of the liquid level meter mounting plate and the through holes on the side wall of the liquid storage tank were easily misaligned, and the coaxiality was difficult to ensure, which in turn affected the normal installation of the liquid level meter. Hole enlargement and rework were often required, which was cumbersome to operate and had low production efficiency. Hole enlargement and rework could also easily affect product quality.

[0038] To this end, the utility model proposes a positioning tool for welding a liquid level gauge mounting plate, which can effectively improve the above-mentioned problem.

[0039] Reference below Figures 1 to 4 The present invention describes a positioning tool for welding a liquid level gauge mounting plate according to an embodiment of the present utility model.

[0040] The positioning tool for welding the liquid level gauge mounting plate according to the embodiment of the utility model is used to position the liquid level gauge mounting plate 600 when the liquid level gauge mounting plate 600 is welded to the side wall of the liquid storage tank 700, such as Figure 1 As shown, the side wall of the liquid storage tank 700 is provided with a through hole 701, and the liquid level meter mounting plate 600 is provided with a mounting hole 601. Specifically, for a liquid level meter, two through holes 701 and two mounting holes 601 can be provided, and mounting columns can be provided at both ends of the liquid level meter, and the two mounting columns are respectively passed through the two mounting holes 601 and the two through holes 701.

[0041] like Figures 2 to 4 As shown, the positioning tool for welding the liquid level gauge mounting plate includes a mounting portion 100 and a positioning pin 200, the positioning pin 200 is arranged on the mounting portion 100, the positioning pin 200 includes a first positioning section 201 and a second positioning section 202, the first positioning section 201 and the second positioning section 202 can both be set to a cylindrical shape, the first positioning section 201 and the second positioning section 202 are coaxially arranged, and the first positioning section 201 and the second positioning section 202 are arranged along the axial direction of the positioning pin 200, the first positioning section 201 is adapted to the through hole 701, that is, the diameter of the first positioning section 201 is close to the aperture of the through hole 701, and the second positioning section 202 is adapted to the mounting hole 601, that is, the diameter of the second positioning section 202 is close to the aperture of the mounting hole 601.

[0042] In the present invention, when the level gauge mounting plate 600 needs to be welded, the level gauge mounting plate 600 is attached to the outer wall of the liquid storage tank 700, and the mounting hole 601 of the level gauge mounting plate 600 is roughly aligned with the through hole 701 on the side wall of the liquid storage tank 700. Then, the positioning tool for welding the level gauge mounting plate is operated to make the positioning pin 200 on the mounting part 100 pass through the mounting hole 601 and the through hole 701, and make the first positioning section 201 of the positioning pin 200 be located in the through hole 701, so that The second positioning section 202 of the positioning pin 200 is located in the mounting hole 601. Since the first positioning section 201 and the second positioning section 202 are coaxial, and the first positioning section 201 is adapted to the through hole 701, and the second positioning section 202 is adapted to the mounting hole 601, the mounting hole 601 of the mounting plate and the through hole 701 on the side wall of the liquid storage tank 700 can be quickly positioned and aligned, thereby ensuring coaxiality and not affecting the normal installation of the subsequent liquid level meter, thereby improving production efficiency and product quality.

[0043] In some embodiments of the present invention, Figures 2 to 4 As shown, the mounting portion 100 is formed with a fitting surface 101, the positioning pin 200 protrudes from the fitting surface 101, and the second positioning section 202 is located at one end of the first positioning section 201 away from the fitting surface 101, and the fitting surface 101 is used to fit the inner surface of the side wall of the liquid storage tank 700. For example, the mounting portion 100 can be a plate-shaped structure, one of the plate surfaces of the mounting portion 100 forms the fitting surface 101, and the positioning pin 200 can be directly welded on the fitting surface 101 or directly formed integrally with the mounting portion 100. In addition, the mounting portion 100 can also be provided with a hole, one end of the positioning pin 200 is installed in the hole, and the portion of the positioning pin 200 having the first positioning section 201 and the second positioning section 202 protrudes from the fitting surface 101, and the second positioning section 202 is farther away from the fitting surface 101 than the first positioning section 201.

[0044] In this embodiment, with such a configuration, when the liquid level gauge mounting plate 600 needs to be positioned, the fitting surface 101 of the mounting portion 100 can be fitted to the inner surface of the side wall of the liquid storage tank 700, and the second positioning section 202 can be inserted into the mounting hole 601 of the liquid level gauge mounting plate 600, and the first positioning section 201 can be inserted into the through hole 701 of the side wall of the liquid storage tank 700. The operation is simple and convenient, saving time and effort. Moreover, since the positioning tool for welding the liquid level gauge mounting plate is located in the liquid storage tank 700, the positioning tool for welding the liquid level gauge mounting plate will not interfere with the welding of the liquid level gauge mounting plate 600, and the practicality is better.

[0045] In some embodiments of the present invention, Figures 2 to 4 As shown, the mounting portion 100 is provided with a magnetic body 300, and the magnetic body 300 is used to be adsorbed on the inner surface of the side wall of the liquid storage tank 700. There can be multiple magnetic bodies 300, for example, two. When the mounting portion 100 is in a long strip shape, multiple magnetic bodies 300 can be arranged along the length direction of the mounting portion 100, and the magnetic body 300 can be a strong magnet. When the fitting surface 101 of the mounting portion 100 fits the inner surface of the side wall of the liquid storage tank 700, and the positioning pin 200 is inserted into the through hole 701 of the side wall of the liquid storage tank 700 and the mounting hole 601 of the liquid level gauge mounting plate 600, the attraction between the magnetic body 300 and the side wall of the liquid storage tank 700 can keep the positioning fixture for welding the liquid level gauge mounting plate immobile, and then when welding the liquid level gauge mounting plate 600, there is no need to hold the positioning fixture for welding the liquid level gauge mounting plate by hand, so as to prevent the positioning fixture for welding the liquid level gauge mounting plate from falling, which is more convenient to use and more practical.

[0046] In some embodiments of the present invention, Figures 2 to 4 As shown, the fitting surface 101 is provided with an embedding groove 102, and the magnetic body 300 is embedded in the embedding groove 102. For example, there may be multiple embedding grooves 102, for example, two. When the mounting portion 100 is in a long strip shape, the multiple embedding grooves 102 may be arranged along the length direction of the mounting portion 100, and the multiple magnetic bodies 300 are respectively embedded in the multiple embedding grooves 102. Such a configuration makes the installation of the magnetic body 300 more convenient and stable, and can reduce the interference caused by the magnetic body 300 on the fitting between the fitting surface 101 and the inner surface of the side wall of the liquid storage tank 700, so that the fitting between the fitting surface 101 and the inner surface of the side wall of the liquid storage tank 700 is more tightly.

[0047] In some embodiments of the present invention, Figures 2 to 4As shown, the end surface of the magnetic body 300 is flush with the fitting surface 101. That is, the surface of the end of the magnetic body 300 away from the end surface of the embedding groove 102 is flush with the fitting surface 101. Such a configuration can not only further reduce the interference of the magnetic body 300 on the fitting between the fitting surface 101 and the inner surface of the side wall of the liquid storage tank 700, thereby making the fitting between the fitting surface 101 and the inner surface of the side wall of the liquid storage tank 700 more closely, but also can make the magnetic body 300 closer to the inner surface of the side wall of the liquid storage tank 700, thereby making the attraction between the magnetic body 300 and the side wall of the liquid storage tank 700 greater and the attraction effect better.

[0048] In some embodiments of the present invention, Figures 2 to 4 As shown, a fastener 400 is provided between the magnetic body 300 and the mounting portion 100. For example, the magnetic body 300 may be provided with a first hole position, and the mounting portion 100 may be provided with a second hole position corresponding to the first hole position, and the fastener 400 may be a cross recessed countersunk screw, and when the magnetic body 300 is fitted into the embedding slot 102, the first hole position is aligned with the second hole position, and then the cross recessed countersunk screw can be installed.

[0049] In this embodiment, such an arrangement can prevent the magnetic body 300 from being randomly removed from the embedding groove 102, thereby making the installation of the magnetic body 300 more stable.

[0050] In some embodiments of the present invention, Figures 2 to 4 As shown, the diameter of the first positioning section 201 is larger than the diameter of the second positioning section 202. Generally, the diameter of the through hole 701 on the side wall of the liquid storage tank 700 is larger than the diameter of the mounting hole 601 of the liquid level meter mounting plate 600. In this embodiment, the diameter of the first positioning section 201 is larger than the diameter of the second positioning section 202, which not only facilitates the second positioning section 202 to pass through the through hole 701, but also enables the first positioning section 201 to fit with the through hole 701, and the second positioning section 202 to fit with the mounting hole 601, which is more practical.

[0051] In some embodiments of the present invention, Figures 2 to 4 As shown, the mounting portion 100 is provided with a gripping portion 500, and the gripping portion 500 protrudes from the side of the mounting portion 100 away from the fitting surface 101. In this embodiment, the gripping portion 500 is provided, and the gripping portion 500 protrudes from the side of the mounting portion 100 away from the fitting surface 101, and the staff can hold the gripping portion 500 to insert the positioning pin 200 into the through hole 701 and the mounting hole 601, or pull the positioning pin 200 out of the through hole 701 and the mounting hole 601, which is more convenient to operate and saves time and effort.

[0052] In some embodiments of the present invention, Figures 2 to 4As shown, the mounting portion 100 is provided with a threaded hole 103, the gripping portion 500 is provided with a bolt structure, and the gripping portion 500 is threadedly connected in the threaded hole 103. The gripping portion 500 is provided with a bolt structure, the outer wall of the gripping portion 500 is provided with an external thread, and the inner wall of the threaded hole 103 is provided with an internal thread. When installing the gripping portion 500, the gripping portion 500 can be threadedly connected in the threaded hole 103 through the matching of the external thread and the internal thread, and the installation and removal of the gripping portion 500 are simple and convenient.

[0053] It should be noted that in some other embodiments of the present invention, the gripping portion 500 may also be directly welded to the mounting portion 100 or formed integrally therewith.

[0054] In some embodiments of the present invention, Figures 2 to 4 As shown, two positioning pins 200 are provided, and the two positioning pins 200 are arranged along the length direction of the mounting portion 100 and are parallel to each other. Since both ends of the liquid level meter are generally provided with mounting columns, correspondingly, the liquid level meter mounting plate 600 is generally provided with two mounting holes 601, and the side wall of the liquid storage tank 700 is generally provided with two through holes 701. In this embodiment, two positioning pins 200 are provided, and the two positioning pins 200 are arranged along the length direction of the mounting portion 100 and are parallel to each other, so that the two mounting holes 601 of the liquid level meter mounting plate 600 can be coaxially aligned with the two through holes 701 of the liquid storage tank 700, respectively, so as to achieve a better positioning effect on the liquid level meter mounting plate 600.
