[0032] Please refer to Figure 3 , Figure 4 and Figure 5 As shown, the test assembly also includes a fixing clamp 24, which is provided with two groups of fixing holes 25. The main shaft of the servo motor 21 is passed through one group of fixing holes 25. Multiple groups of handle screws 26 are correspondingly provided on both sides of the fixing clamp 24, thereby enhancing the stability of the fixing clamp 24.

[0033] Please refer to Figure 4 and Figure 5As shown, a vertical axis connecting rod 27 is passed through another set of fixing holes 25 of the fixing clamp 24, and a transverse connecting rod 28 is clamped at the bottom end of the vertical axis connecting rod 27, and an operating fork 29 is further provided at the bottom end of the transverse connecting rod 28; it is worth mentioning that the valve core product 13 to be tested is located in the operating fork 29; by starting the servo motor 21, its rotating main shaft drives the vertical axis connecting rod 27 to rotate, and then drives the transverse connecting rod 28 and the operating fork 29, so as to realize the repeated opening and closing action of the valve core product 13.

[0034] In addition, the device has the characteristics of automation; first, it can realize an uninterrupted automatic testing process, greatly improving the overall testing efficiency. The operator does not need to carry out continuous manual intervention throughout the test. The device can autonomously perform repeated opening and closing actions under pre-set parameters and record relevant performance data in real time; this not only improves the continuity and stability of the test, but also greatly reduces labor costs; compared with the traditional testing method that relies on manual operation, it not only requires more personnel training and management costs, but also it is difficult to ensure the continuity of the test. The device, relying on the advantages of automation, can perform life tests on valve core products 13 for a long time without interruption, without too much manual participation, effectively saving precious human resources.

[0035] Please refer to Figure 2 , Figure 6 and Figure 7 As shown, a mounting hole 15 is provided on the test platform 12, and a limiting base 31 is fixed to the top of the mounting hole 15 by multiple sets of screws. A plurality of sets of double-wing hand screws 32 are also provided on the peripheral side of the limiting base 31, and one end of these double-wing hand screws 32 can directly contact the valve core product 13 to be tested, thereby achieving a stable fixation of the valve core product 13; the operator only needs to use these double-wing hand screws 32 to perform simple manual adjustments to conveniently install the valve core product 13 on the test device, which greatly improves the flexibility and convenience of clamping; this fixing mechanism combining the limiting base 31 and the double-wing hand screws 32 not only ensures the stability of the valve core product 13 and avoids the problem of shaking or displacement during the test, but also simplifies the operation process to the maximum extent and improves the overall user experience.

[0036] Please refer to Figure 6 and Figure 7As shown, the fixing component also includes a limited base frame 33, and a plurality of through holes are provided at the bottom of the test platform 12.

This adjustable structure can easily adapt to valve core products 13 of different specifications, and is convenient for later maintenance and replacement. In addition, the structure is simple and convenient for maintenance, which prolongs the service life of the device and reduces the long-term cost.

[0037] A controller 41 is installed on one side of the installation box 14. On the same side of the installation box 14, a servo motor 21 and an Omron proximity sensor 22 are also provided.

At the bottom of these two indicator lights, a stop button 44 and a start button 45 are respectively provided. The operator can use these two buttons to quickly start or stop the entire test device.

[0038] Please refer to Figure 2 As shown, in addition, a plurality of groups of transparent acrylic baffles 16 are arranged around the iron frame 11 of the test device. The arrangement of these baffles 16 not only plays a protective role, but also increases the aesthetics of the entire device; more importantly, two groups of sensing gratings 17 are arranged on the inner side of the iron frame 11. These sensing gratings 17 can monitor in real time whether there are foreign objects entering the test area. Once an abnormal situation is detected, the operation of the test device will be stopped immediately, which effectively prevents accidents and greatly improves the safety of operators.

[0039] Specific usage and function of this embodiment: When using the device, first, the operator places the valve core product 13 to be tested stably on the limiting base frame 33 to ensure that the product position is stable. Then, the valve core product 13 is fixed by the limiting base frame 33 and multiple sets of butterfly nuts 35 to avoid loosening during the test. Subsequently, the multiple sets of positioning rods 34 are adjusted to adapt them to the specific dimensions of the valve core product 13.

[0040] Then, the operator sets the test parameters through the controller 41, such as a rotation angle of 90 degrees each time and a total number of cycles of 200,000 times. After the settings are completed, the start button 45 is pressed. At this time, the operating status indicator light 43 lights up, indicating that the equipment starts to run automatically. At the end of each cycle, the controller 41 will automatically record data until all 200,000 cycles are completed.

[0041] When the test is finished, the alarm indicator light 42 will flash to prompt the operator to view the test results. During the test, the operator does not need to monitor for a long time or intervene frequently, which greatly improves the efficiency and consistency of the test. In addition, an Omron proximity sensor 22 is arranged on one side of the installation box 14, which is electrically connected to the servo motor 21 and the controller 41, and can monitor the operating status of the servo motor 21 to ensure the reliability of the test process. At the same time, multiple groups of transparent acrylic baffles 16 and two groups of induction gratings 17 are arranged around the iron frame 11, which can monitor abnormal conditions during the test in real time and give timely alarms.
