Description

Technical Field

[0001] This utility model relates to the field of water heater testing fixtures, specifically to a testing fixture. Background Technology

[0002] A water heater is a device that heats water for domestic or commercial use, and is widely used for bathing, washing, and kitchen water use. A water heater typically includes a casing, as well as components such as a burner and a heat exchanger housed within the casing. The casing has multiple mounting holes, as well as an inlet and an outlet that connect to the heat exchanger. Cold water entering from the inlet is heated by the heat exchanger, and hot water is then output from the outlet.

[0003] After the water heater is manufactured, the positions of the connection holes, as well as the positions of the liquid inlet and outlet, need to be inspected to ensure that the positions of the multiple connection holes, as well as the positions of the liquid inlet and outlet, meet the preset requirements. In the existing technology, measuring tools are usually used to measure the distance between the test holes, the liquid inlet and outlet and the reference edge or reference surface. The inspection time is long, the accuracy is limited, and the error is large due to the influence of human reading, which can easily lead to inaccurate test results. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] To address the technical problem in existing technologies where it is inconvenient to determine the positions of multiple connection holes on a water heater, as well as whether the inlet and outlet positions meet preset requirements, this solution provides a testing fixture. This fixture can detect the positions of the connection holes, as well as the inlet and outlet positions of the water heater, improving testing speed and accuracy, and ensuring the production quality of the water heater.

[0028] Please see Figures 1-6 , Figures 1-6 This invention provides a testing fixture for detecting the positions of the connection holes, inlet end, and outlet end of a water heater A. The fixture includes a testing platform 1, multiple hole position detection mechanisms 2, and a port detection mechanism 3. The multiple hole position detection mechanisms 2 are detachably connected to the testing platform 1. Each hole position detection mechanism 2 has a supporting end face 21 and a protrusion 22. The port detection mechanism 3 is detachably mounted on the testing platform 1 and has two spaced-apart alignment portions 31. When the multiple protrusions 22 are correspondingly inserted into each of the connection holes, and each supporting end face 21 abuts against the water heater, the two alignment portions 31 correspond to the inlet end and the outlet end, respectively.

[0029] In actual use, according to the model of water heater A, a hole position detection mechanism 2 with the same number of connection holes as water heater A is installed on the detection platform 1. At the same time, a port detection mechanism 3 is installed on the detection platform 1. When multiple protrusions 22 are inserted into each connection hole in a corresponding manner, and each support end face 21 abuts against the water heater, the two pairs of positioning parts 31 can correspond to the liquid inlet and liquid outlet respectively. It can then be determined that the positions of the connection holes, liquid inlet and liquid outlet of the water heater A meet the preset requirements.

[0030] It should be noted that, in one embodiment, the testing platform 1 has multiple through holes 1a, and the hole position detection mechanism 2 also has a positioning part, which can be inserted into the through hole 1a; it is understood that for different models of water heater A, the position of the connection hole on water heater A will also be different. When using it, multiple hole position detection mechanisms 2 and port detection mechanisms 3 need to be installed on the testing platform 1 according to the water heater A that meets the design requirements.

[0031] In one embodiment, such as Figure 5 As shown, water heater A has four connection holes, which are detected by four hole position detection mechanisms 2. It should be noted that the hole position detection mechanism 2 is not limited to a specific structure, as long as it has a supporting end face 21 and a protrusion 22. The height of each supporting end face 21 and the size of the protrusion 22 can be designed according to the actual situation, and no other restrictions are made here. Specifically, two hole position detection mechanisms 2 are spaced apart on one side of the detection platform 1, and the other two hole position detection mechanisms 2 are spaced apart on the other side of the detection platform 1.

[0032] In another embodiment, such as Figure 6 As shown, water heater A has six connection holes, which means that the six connection holes need to be tested by six hole position detection mechanisms 2 respectively. It should be noted that three hole position detection mechanisms 2 are spaced apart on one side of the detection platform 1, and three hole position detection mechanisms 2 are spaced apart on the other side of the detection platform 1.

[0033] Based on the above scheme, in order to improve the installation stability of the hole position detection mechanism 2, specifically, a collar is fixed on the inner wall of the perforation 1a, wherein the collar is an elastic rubber collar. When the positioning part is inserted into the perforation 1a, the positioning part can cause the collar to undergo elastic deformation, and the collar can generate a rebound force to restore its original shape. This force forms a radial preload on the surface of the positioning part.

[0034] It should be noted that this testing fixture can be used to test two different models of water heaters. Depending on the model of the water heater, a four-hole testing mechanism 2 or a six-hole testing mechanism 2 can be installed on the testing platform 1.

[0035] It should be noted that, in one embodiment, the port detection mechanism 3 includes a first mounting block 32, the first mounting block 32 is provided with a first limiting part 321, the detection stage 1 is provided with a limiting hole 1b, the first limiting part 321 can be inserted into the limiting hole 1b, and the two alignment parts 31 are provided on the first mounting block 32.

[0036] Based on the above scheme, in order to adjust the installation height of the two alignment parts 31, the port detection mechanism 3 further includes at least one second mounting block 33. The second mounting block 33 is provided with a second limiting part 331 and a groove is also provided on the second mounting block 33. The second limiting part 331 can be inserted into the limiting hole 1b, and the first limiting part 321 can be inserted into the groove.

[0037] It is understood that by adding a second mounting block 33, with the second limiting part 331 on the second mounting block 33 being inserted into the limiting hole 1b, and the first limiting part 321 on the first mounting block 32 being inserted into the groove, the vertical height between the two alignment parts 31 and the detection stage 1 can be adjusted.

[0038] It should be noted that the limiting hole 1b of the first limiting part 321 on the first mounting block 32 can satisfy the two alignment parts 31 to detect one type of water heater; in this specific embodiment, there is one second mounting block 33. When the first mounting block 32 and the second mounting block 33 are connected, the two alignment parts 31 can detect another type of water heater.

[0039] Specifically, based on the above scheme, in order to improve the installation stability between the port detection mechanism 3 and the detection table 1, the inner wall of the limiting hole 1b and the groove are provided with elastic gaskets. The elastic gaskets are elastic rubber gaskets. It should be noted that the function of the elastic gaskets is the same as that of the collar, and no further details will be provided here.

[0040] It should be noted that, in this specific embodiment, the supporting end face 21 is a circular supporting end face, the protrusion 22 is a columnar protrusion, the positioning part is cylindrical, and the through hole 1a is a circular through hole.

[0041] Furthermore, it should be noted that the inlet and outlet ends of water heater A are spaced apart, and both the inlet and outlet ends are annular tubes. In this specific embodiment, both of the aforementioned aligning parts 31 are annular sleeves. When the inlet and outlet ends correspond to the two annular sleeves respectively, the central axes of the inlet and outlet ends coincide with the central axes of the two annular sleeves respectively.

[0042] In addition, based on the above solution, in order to facilitate the handling and movement of the testing table 1, specifically, both ends of the testing table 1 are provided with handles 11 for lifting the testing table 1. The operator can carry the testing table 1 by holding the two handles 11 with both hands.

[0043] It should be noted that, in order to reduce the mass of the testing station 1, the testing station 1 is specifically made of an alloy plate. Of course, in other embodiments, the testing station 1 can also be made of a plastic plate.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
