Description

Technical Field

[0001] This utility model belongs to the technical field of speed reducer testing equipment, specifically relating to a speed reducer sealing testing device. Background Technology

[0002] Gearbox sealing testing devices are specialized equipment designed for the sealing structures of gearboxes, such as housings and oil seals. They utilize core principles like gas pressurization, pressure monitoring, and leak identification to determine whether the sealing performance meets standards. Their core functions include accurately identifying leak points and quantifying leakage amounts, preventing equipment failures caused by lubricating oil leakage and impurity intrusion. These devices encompass various types, including simple immersion type, intelligent airtight type, and sensor-monitored type. Structurally, they integrate sealing fixtures, pneumatic units, and detection sensors, adapting to different precision, batch sizes, and operating conditions. They are widely used in industrial machinery, robotics, wind power, and other fields.

[0003] However, while immersion testing has the advantages of simple structure and low operation threshold, there are significant limitations in the process. It is necessary to first seal key interfaces such as the inlet and outlet of the reducer and the mounting holes by sealing the tooling, then inject gas at a set pressure into the inside, and then immerse it in a water container. The whole process relies on manual observation of bubbles to determine whether there is a leak. However, the bubbles generated by tiny cracks are small in size and easily dissipate, making them easy to be overlooked by operators. This not only seriously affects the accuracy of the test results, but also leads to poor overall test results, making it difficult to meet the requirements of high-precision testing.

[0004] To address the aforementioned issues, this application proposes a speed reducer sealing performance testing device. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a speed reducer sealing test device, which has the characteristic of improving the test effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a speed reducer sealing performance testing device, comprising a testing water tank, a controller, a display, and an air pump respectively arranged on the front of the testing water tank, a movable frame and a support frame respectively arranged above the testing water tank, an electric push rod and two multi-section electric telescopic rods respectively fixedly connected to the inner wall of the support frame, a hanging ring fixedly connected to the telescopic end of the electric push rod, the telescopic ends of the two multi-section electric telescopic rods being fixedly connected to the upper surface of the movable frame, and industrial cameras arranged at equal intervals inside the movable frame.

[0007] As a preferred embodiment of this utility model, the bottom surface of the testing pool is fixedly connected to two sets of connecting columns, and the bottom end of each connecting column is fixedly connected to a support ring.

[0008] As a preferred embodiment of this utility model, a viewing plate is snapped onto the left side of the testing pool, a fixing frame is fixedly connected to the outer surface of the viewing plate, and the right side of the fixing frame is fixedly connected to the left side of the testing pool.

[0011] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the bottom surface of the support frame, and the left side of the fixing plate is fixedly connected to the right side of the testing water tank.

[0012] As a preferred embodiment of this utility model, a reinforcing plate is fixedly connected to the upper surface of the support frame, and the inner wall of the reinforcing plate is fixedly connected to the outer surface of the electric push rod and the two multi-section electric telescopic rods.

[0013] As a preferred embodiment of this utility model, each of the industrial cameras has a fixed ring fixedly connected to its outer surface, and the side of each set of fixed rings that is far apart from each other is fixedly connected to the inner wall of the moving frame.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: By setting up an electric push rod and a hanging ring, the reducer can be automatically immersed in or removed from the testing water tank, replacing the traditional manual hoisting, avoiding gas leakage caused by operational deviations, and improving the stability of the testing process. At the same time, through the multi-section electric telescopic rod, the moving frame, and the waterproof industrial cameras arranged at equal intervals, the underwater state of the reducer can be captured from multiple angles, accurately capturing tiny bubbles generated by minute cracks, solving the pain point of easy omissions in traditional manual observation, and greatly improving the accuracy of testing. Furthermore, through the coordinated operation of the controller, display, air pump, and industrial camera, the testing process can be semi-automated, and the testing data can be displayed in real time, making it easy for operators to intuitively judge the results, while reducing manual intervention and improving testing efficiency. The support frame and other components in the overall structure ensure the stability of equipment operation, adapt to the testing needs of reducers of different specifications, are easy to operate and highly practical, and effectively make up for the defects of poor testing effect or cumbersome operation of traditional immersion testing devices.

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.

[0024] Example

[0025] Please see Figure 1-6 The present invention provides the following technical solution: a speed reducer sealing test device, including a test water tank 1, a controller 8, a display 6 and an air pump 10 respectively arranged on the front of the test water tank 1, a movable frame 17 and a support frame 11 respectively arranged above the test water tank 1, an electric push rod 14 and two multi-section electric telescopic rods 16 respectively fixedly connected to the inner wall of the support frame 11, a hanging ring 15 fixedly connected to the telescopic end of the electric push rod 14, and the telescopic ends of the two multi-section electric telescopic rods 16 are fixedly connected to the upper surface of the movable frame 17, and industrial cameras 19 arranged at equal intervals are arranged inside the movable frame 17;

[0026] In this embodiment, the controller 8 adopts a PLC programmable logic controller, which supports multi-device linkage control. It can preset relevant parameters to realize the coordinated action of electric push rod 14, multi-section electric telescopic rod 16, air pump 10 and industrial camera 19, and has data storage and signal feedback functions. Meanwhile, the display 6 adopts an industrial touch screen, which has waterproof and dustproof characteristics and can display detection-related information in real time. It supports touch operation to adjust parameters. The air pump 10 adopts a miniature silent air compressor, equipped with a pressure sensor and pressure relief valve, which can stably output the set pressure gas with noise that meets the requirements of the workshop working environment. The electric push rod 14 adopts a ball screw electric push rod with a self-locking function to ensure the stability of the position after the reducer is immersed in water. The two multi-section electric telescopic rods 16 adopt aluminum alloy electric telescopic arms to adapt to the camera shooting position adjustment requirements. In addition, the industrial camera 19 adopts a waterproof industrial CCD camera with a protection level that meets the requirements of underwater operation. It is equipped with an anti-fog lens and infrared supplement light, which can clearly capture tiny bubbles underwater and supports real-time image transmission. The selection of each component is adapted to the functional requirements of the device, taking into account both practicality and economy.

[0027] Specifically, two sets of connecting columns 4 are fixedly connected to the bottom surface of the test pool 1. Each connecting column 4 has a support ring 5 fixedly connected to its bottom end. In this embodiment, the cooperation between the connecting column 4 and the support ring 5 forms a stable support for the test pool 1, preventing it from directly contacting the ground and causing the bottom to become damp and corroded. At the same time, it improves the overall stability of the device and prevents the test accuracy from being affected by the shaking of the pool during the test.

[0028] Specifically, a viewing plate 2 is snapped onto the left side of the testing pool 1, and a fixing frame 3 is fixedly connected to the outer surface of the viewing plate 2. The right side of the fixing frame 3 is fixedly connected to the left side of the testing pool 1. In this embodiment, the viewing plate 2 is securely installed on the side of the testing pool 1 by the fixing frame 3, which not only ensures the installation of the viewing plate 2, but also allows for direct observation of the internal testing conditions of the pool through the viewing plate 2. This facilitates the operator to monitor the immersion status of the reducer and the generation of bubbles in real time, and helps to judge the test results.

[0029] Specifically, a connecting plate 7 is fixedly connected to the front of the testing pool 1. The front of the connecting plate 7 is fixedly connected to the back of the controller 8 and the display 6. In this embodiment, the connecting plate 7 provides a stable mounting carrier for the controller 8 and the display 6, so that the two and the testing pool 1 form an integrated structure, which saves installation space and ensures the compactness of the equipment connection, and avoids the controller 8 or the display 6 from shifting or being damaged due to collision during use.

[0030] Specifically, a support plate 9 is fixedly connected to the bottom surface of the air pump 10. The back of the support plate 9 is fixedly connected to the front of the test water tank 1. In this embodiment, the air pump 10 is supported and fixed by the support plate 9, so that the air pump 10 and the test water tank 1 maintain a relatively fixed positional relationship. This ensures that the pipe connected to the air pump 10 and the reducer is under stable force, avoids pipe detachment or air leakage due to displacement of the air pump 10, and ensures the stability of the inflation test.

[0031] Specifically, a fixing plate 12 is fixedly connected to the bottom surface of the support frame 11. The left side of the fixing plate 12 is fixedly connected to the right side of the test water tank 1. In this embodiment, the support frame 11 is firmly installed on one side of the test water tank 1 by the fixing plate 12, which increases the contact area between the support frame 11 and the test water tank 1, improves the installation stability of the support frame 11, and ensures that it can reliably bear the weight of components such as the electric push rod 14 and the multi-section electric telescopic rod 16, and avoids equipment operation deviation due to the loosening of the support frame 11 during the test.

[0032] Specifically, a reinforcing plate 13 is fixedly connected to the upper surface of the support frame 11. The inner wall of the reinforcing plate 13 is fixedly connected to the outer surface of the electric push rod 14 and the two multi-section electric telescopic rods 16. In this embodiment, the electric push rod 14 and the multi-section electric telescopic rods 16 are fixedly fixed by the reinforcing plate 13 to enhance the connection between the two and the support frame 11, prevent them from shaking or deviating during the telescopic movement, and ensure the accuracy of the reducer lifting and the camera moving.

[0033] Specifically, each industrial camera 19 has a fixed ring 18 fixedly connected to its outer surface. The side of each set of fixed rings 18 that is far apart from each other is fixedly connected to the inner wall of the moving frame 17. In this embodiment, the industrial camera 19 is stably installed inside the moving frame 17 by the fixed rings 18, which ensures that the installation position of the industrial camera 19 is accurate and stable, avoids the camera from shifting due to water flow impact or equipment vibration during underwater detection, and ensures that the camera can stably shoot from a preset angle and accurately capture the bubble signal on the surface of the reducer.

[0034] The working principle and usage process of this utility model are as follows: First, the key interfaces such as the inlet and outlet, and mounting holes of the reducer to be tested are sealed using a sealing fixture. Then, the reducer is fixed to the hanging ring 15 at the bottom of the electric push rod 14 with ropes. The controller 8 presets parameters such as inflation pressure, lifting stroke of the electric push rod 14, and shooting time of the industrial camera 19. After starting the device, the controller 8 controls the electric push rod 14 to extend, smoothly immersing the reducer in the water of the testing pool 1. After the reducer is completely submerged, the electric push rod 14 maintains a stable position through a self-locking function. Subsequently, the air pump 10 starts, injecting gas at the set pressure into the reducer through a sealed pipe. Simultaneously, the controller 8 controls the extension and retraction of the multi-section electric telescopic rod 16, adjusting the position of the moving frame 17 so that the industrial camera 19 is aligned with the reducer. On each inspection surface, the industrial camera 19 captures real-time images of bubble formation on the surface of the underwater reducer. The captured images and pressure data from the air pump 10 are simultaneously transmitted to the controller 8. After processing, the data is displayed in real-time on the monitor 6. Operators can visually view the inspection data and images on the monitor 6, and can also use the viewing panel 2 to observe the internal state of the water tank. If the industrial camera 19 captures tiny bubbles or abnormal pressure data during the inspection, the controller 8 will automatically determine that it is unqualified and issue a prompt. If the inspection is qualified, the data is recorded and stored. After the inspection is completed, the controller 8 controls the air pump 10 to depressurize, the electric push rod 14 retracts to move the reducer out of the water, and the multi-section electric telescopic rod 16 resets. The operator can then remove the reducer to complete a single inspection. The overall process is highly automated, and the inspection is accurate and efficient.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
