The front side of the column support 1 is also provided with a bearing bearing platform 7.

[0017] The column support 1 is the main frame of the entire device.

[0018] The bearing support platform 7 includes a lower base plate 71, a guide rail 72, an intermediate connecting plate 73, a displacement cylinder 74, an airtight chamber 75 and a bearing placement plate 76. Guide rails 72 are arranged on both sides of the lower base plate 71. The slider at the upper end of the guide rail 72 is connected to the intermediate connecting plate 73. The telescopic end of the displacement cylinder 74 is connected to the lower surface of the intermediate connecting plate 73. An intermediate support shaft 77 is arranged around the intermediate connecting plate 73. The upper end of the intermediate support shaft 77 is connected to the bearing placement plate 76. The airtight chamber 75 is located on the lower surface of the bearing placement plate 76. A vacuum pumping device 8 is arranged on one side of the airtight chamber 75. A pressure sensor 9 for detecting pressure changes is arranged on the outer side of the airtight chamber 75.

[0019] The lower base plate 71 serves as the basic component of the bearing support platform 7. The lower base plate 71 provides a stable installation platform, supports the weight of the entire bearing support platform 7, and ensures the stable installation of various components; the guide rails 72 are located on both sides of the lower base plate 71, and the guide rails 72 are connected to the intermediate connecting plate 73 through sliders, allowing the intermediate connecting plate 73 to move smoothly in a specific direction, thereby improving the flexibility and accuracy of adjusting the position of the components on the support platform; the displacement cylinder 74 is a driving element, and its extension and retraction directly controls the up and down movement of the intermediate connecting plate 73. Through precise control, the height of the bearing placement plate 76 can be fine-tuned, thereby improving the adaptability of the detection; the intermediate support shaft 77 enhances the rigidity of the entire system, and also ensures smooth lifting and lowering driven by the displacement cylinder 74 to prevent deflection or shaking; the bearing placement plate 76 carries the bearing to be tested, and through the connection with the intermediate support shaft 77, the stability of the bearing position during the test can be ensured; when the bearing is pressed, the airtight chamber 75 creates a closed test environment through the vacuum pumping device 8 for detecting the sealing performance of the bearing. Any leakage will cause a change in the pressure in the airtight chamber 75, which will be captured by the pressure sensor 9; the vacuum device 8 is responsible for extracting the air in the airtight chamber 75 to create the necessary vacuum conditions. The pressure sensor 9 is installed on the outside of the airtight chamber 75 to monitor the changes in the internal pressure of the airtight chamber 75 in real time. It is a key tool for evaluating whether the bearing sealing performance meets the standards.

[0020] Furthermore, a cylinder mounting seat 10 is also provided on the sliding guide seat 2 , and a pressing cylinder 5 is installed on the horizontal end of the cylinder mounting seat 10 .

[0021] The cylinder mounting base 10 provides a stable mounting platform for the clamping cylinder 5 , ensures the stability of the clamping cylinder 5 during operation, prevents positional displacement due to vibration or external force, and helps to evenly distribute the weight of the clamping cylinder 5 and the force generated during operation.

[0022] Furthermore, a sealing strip 11 is provided on the lower surface of the bearing placement plate 76 , and the sealing strip 11 is located between the airtight chamber 75 and the bearing placement plate 76 .

[0023] The sealing strip 11 ensures the sealing effect between the airtight chamber 75 and the bearing placement plate 76, preventing air from leaking from the edge during the vacuuming process, thereby creating a more stringent vacuum environment and improving the accuracy of testing the bearing sealing performance.

[0024] The sealing strip 11 is usually made of elastic material and can adapt to the bottom contour of the bearing of different shapes and sizes to form a tight fit. It can maintain a good sealing state even when there is a slight displacement caused by changes in air pressure, thereby increasing the versatility and reliability of the test.

[0025] Furthermore, the upper end of the bearing placement plate 76 is provided with a first bearing placement seat 12, a second bearing placement seat 13 and a third bearing placement seat 14 in sequence.

[0026] Different bearing seats can adapt to bearings of different models or sizes, which increases the application range of the device. Users can choose the appropriate bearing seat for testing according to actual needs, which enhances the flexibility of detection.

[0027] Furthermore, air guide holes are provided in the middle of the first bearing seat 12 , the second bearing seat 13 and the third bearing seat 14 , and the air guide holes are connected to the airtight chamber 75 .

[0028] By connecting the airtight chamber 75, the air guide holes allow each area below the bearing to be subjected to the same degree of vacuum, and even the smallest leak can be detected through pressure changes, thereby improving the sensitivity and reliability of the bearing sealing performance detection.

[0029] When in use: according to the size and type of the bearing to be tested, select the appropriate first bearing seat 12, the second bearing seat 13 or the third bearing seat 14, and place the bearing correctly thereon. Ensure that the bearing and the placement seat match closely to avoid unnecessary movement during the test, use the displacement cylinder 74 to adjust the position of the intermediate connecting plate 73, and then change the height of the bearing placement plate 76, adjust the position of the bearing to be tested located on the first bearing seat 12, the second bearing seat 13 or the third bearing seat 14 to the lower pressure seat 6 to meet the test requirements of bearings of different sizes, and ensure that there is no leakage in the airtight chamber 75 and the bearing placement plate 76; turn on the vacuum pumping device 8, and start to extract the air in the airtight chamber 75 until the predetermined vacuum degree is reached; in this process, the pressure difference change inside and outside the airtight chamber is monitored by the pressure sensor 9 to ensure that the vacuum environment is successfully established, and the pressing cylinder 5 applies downward pressure through the cylinder connecting frame 4, and the lower pressure seat 6 applies a predetermined test pressure to the bearing to simulate the load condition under the working state. At this time, the pressure inside the airtight chamber is continuously monitored by the pressure sensor 9, and any pressure changes caused by poor bearing sealing are recorded. After the test is completed, the data of the pressure sensor 9 is observed and recorded to analyze the sealing performance of the bearing. If the pressure remains stable, it indicates that the bearing is well sealed; if there is a significant pressure drop, there may be a leakage problem.
