[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figure 1 and Figure 7 As shown, in this embodiment, the present invention includes a water tank 1 that can be placed on the assembly line table and a test fixing plate 2. The test fixing plate 2 is disposed on the top of the water tank 1. The water tank 1 is used to contain test water. The test fixing plate 2 is provided with a test pressure gauge 3, a motor positioning assembly 4, a water pipe assembly 5, and a valve assembly 6. The motor positioning assembly 4, the test pressure gauge 3, and the valve assembly 6 are interconnected and cooperate with each other through the water pipe assembly 5. The motor positioning assembly 4 is used to limit the motor under test. The test pressure gauge 3 is used to test the motor under test. The valve assembly 6 is used to control the opening and closing of the water circuit. Therefore, the water tank 1 serves to contain the test water and provide a stable water circulation for the entire testing system. The test fixing plate 2 is the mounting base for the tooling, supporting and installing the test pressure gauge 3, the motor positioning assembly 4, the water pipe assembly 5, and the valve assembly 6, ensuring the stability of each component during testing. The test pressure gauge 3 monitors the performance parameters of the motor under test in real time. The motor positioning assembly 4 fixes the motor under test, ensuring its axis is aligned with the motor positioning assembly 4, avoiding water pressure leakage or measurement errors caused by misalignment during testing. The water pipe assembly 5 forms a closed water circulation path, connecting and cooperating with the water tank 1, the motor positioning assembly 4, the test pressure gauge 3, and the valve assembly 6 to realize water delivery and return. The valve assembly 6 controls the opening and closing of the water path. This utility model's structural optimization and modular integration achieves an efficient and accurate motor testing solution, significantly reducing labor costs and defect rates, and improving testing efficiency for batch motor testing on assembly lines.
[0028] Furthermore, in this embodiment, the motor positioning assembly 4 includes a test positioning mold 40 and a limiting fixing plate 41. The test positioning mold 40 is mounted on the limiting fixing plate 41 and is used to position the motor under test. The limiting fixing plate 41 is provided with limiting protrusions 410, which engage with the motor under test for limiting. Thus, the test positioning mold 40 uses a contoured structure to limit the motor's axis, ensuring stability during testing. The limiting fixing plate 41 serves as the mounting base for the test positioning mold 40, providing stable structural support. The limiting fixing plate 41 also supports and fixes the limiting protrusions 410. The limiting protrusions 410 engage with the external structure of the motor under test to prevent rotation or translation during testing. Friction protrusions are provided on the mating surface between the limiting protrusions 410 and the motor under test to enhance friction and prevent vibration during testing from causing the motor to loosen, thus affecting test stability.
[0029] Furthermore, in this embodiment, the top surface of the water tank 1 is open, and mounting sides 10 are provided around the top surface. The test fixing plate 2 is limited and fitted on the mounting sides 10. A transparent plate 7 is provided on the test fixing plate 2. The transparent plate 7 is used to observe the test status of the motor under test and to prevent water from spraying out. Thus, the purpose of the open top surface of the water tank 1 is to place and facilitate the replacement of the test fixing plate 2, while also facilitating direct water filling and water level observation. The mounting sides secure the test fixing plate 2 tightly to the top of the water tank 1 with bolts, preventing the test fixing plate 2 from moving freely during testing and preventing test water from spraying out of the opening. The transparent plate 7 serves to observe the test status of the motor under test, improving operational safety.
[0030] Furthermore, in this embodiment, the water pipe assembly 5 includes a tee connector 50 and a connecting pipe 51. The tee connector 50 has a first interface, a second interface, and a third interface. The first interface is connected to the motor positioning assembly 4, the second interface is connected to the valve assembly 6, and the third interface is connected to one end of the connecting pipe 51. The other end of the connecting pipe 51 is connected to the test pressure gauge 3. Thus, the tee connector 50 serves to distribute water flow and transmit pressure. The first interface, connected to the motor positioning assembly 4, forms the main test water path. The second interface, connected to the valve assembly 6, controls the start or stop of the test. The third interface, connected to the test pressure gauge 3, monitors the water pressure. The connecting pipe 51 is a flexible hose, serving as a connection between the high-pressure water path and the test pressure gauge 3, transmitting the test water pressure to the test pressure gauge 3. The flexible hose also prevents vibration from interfering with the stability of the test.
[0031] Furthermore, in this embodiment, the test fixing plate 2 is provided with several threaded holes, which cooperate with bolts to install and fix the test pressure gauge 3, the motor positioning assembly 4, and the valve assembly 6. Thus, the test fixing plate 2 provides support and fixation for the several threaded holes. The design of the threaded holes cooperating with bolts facilitates the independent installation and removal of the fixed test pressure gauge 3, motor positioning assembly 4, and valve assembly 6, making maintenance and replacement easier. At the same time, the layout of the several threaded holes can be adjusted to support test pressure gauges 3, motor positioning assemblies 4, or valve assemblies 6 of different sizes, reducing design costs and improving equipment versatility.
[0032] Optionally, in this embodiment, the inner wall of the water tank 1 is provided with an anti-rust coating, which is an epoxy resin coating or a polytetrafluoroethylene coating. Therefore, the epoxy resin coating or polytetrafluoroethylene coating used in the water tank 1 prevents corrosion and extends the service life of the water tank 1.
[0033] Furthermore, in this embodiment, a drain valve is provided at the bottom of the water tank 1, which is used to drain the test water in the water tank 1. Thus, the purpose of the drain valve in the water tank 1 is to ensure complete drainage using gravity, facilitating the replacement of the test water. When testing is not required, the test water is drained to prevent the growth of microorganisms or insects, ensuring the reliability of the water tank 1 and extending the equipment's lifespan.
[0034] Furthermore, in this embodiment, a water level observation window is provided on the side of the water tank 1, which is used to observe the water level height inside the water tank 1. Therefore, the water tank 1 is equipped with a water level observation window, which allows operators to directly observe and judge the water level in the water tank 1, avoiding test interruptions due to insufficient water level or overflow due to excessive water level, and providing an efficient and stable testing environment.
[0035] Furthermore, in this embodiment, the transparent plate 7 is an acrylic plate or a polycarbonate plate, and the transparent plate 7 is sealed to the edge of the opening provided on the test fixing plate 2 by a sealing strip. Therefore, the use of acrylic or polycarbonate plates for the transparent plate 7 maintains high transparency, ensuring that operators can clearly observe the motor test status. It is also scratch-resistant, has good physical stability, and can withstand sudden unexpected events such as sudden changes in water pressure during testing. The sealing strip serves to fill and seal, preventing high-pressure water from spraying out from the edge of the transparent plate during testing, thus protecting the operator's safety.
[0036] Furthermore, in this embodiment, the connecting pipe 51 is a flexible hose, and its two ends are connected to the test pressure gauge 3 and the tee connector 50 respectively via quick-release couplings. Thus, the flexible hose absorbs vibration energy through bending deformation, reducing mechanical impact on the pressure gauge. The quick-release couplings connect / disconnect via snaps or threaded knobs, significantly shortening component replacement time. The design of the connecting pipe 51 achieves a balance between testing accuracy, operational efficiency, and equipment reliability through vibration isolation from the flexible hose, rapid maintenance via the quick-release couplings, high-pressure sealing, and optimized durability.
[0037] The working principle of this utility model is as follows:
[0038] The operator positions the motor under test on the motor positioning assembly 4, and then starts turning the valve assembly 6. The test fixture begins to work, and the operator begins to observe the value of the test pressure gauge 3. At the same time, the operator observes the state of the test water in the water tank 1 through the transparent plate 7. After the motor completes the test, the motor is removed, and the next motor is tested again, and so on.
[0039] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0040] The above embodiments do not limit the scope of protection of this utility model. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this utility model shall still fall within the scope of this utility model.
