[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1
[0029] Reference Figures 1-7 As a first embodiment of the present invention, a shaft damping life testing machine is provided. This device includes, The components include: a support foot 101, an adjusting nut 102 threaded onto the surface of the support foot 101, a base plate 103 sleeved on the surface of the support foot 101, a support frame 104 fixedly connected to the side wall of the base plate 103, a mounting assembly 105 fixedly connected to the side wall of the support frame 104, a counting assembly 106 fixedly connected to one side of the mounting assembly 105, a drive assembly 107 fixedly connected to the other side of the mounting assembly 105, and a connecting assembly 108 fixedly connected to the surface of the counting assembly 106. The drive assembly 107 includes a motor mount 107a, a drive motor 107b adapted to be mounted on the side wall of the motor mount 107a, a drive rod 107c fixedly connected to the output end of the drive motor 107b, and a connecting groove 107d formed on the surface of the drive rod 107c.
[0030] Specifically, there are two sets of adjusting nuts 102, stacked on both sides of the base plate 103. The adjusting nuts 102 located below the base plate 103 facilitate the adjustment of the height of the base plate 103, while the adjusting nuts 102 located on the upper side of the base plate 103 work together with the lower adjusting nuts 102 to secure the adjusting nuts 102 and ensure the stability of the height of the base plate 103. The drive motor 107b is a servo motor, which facilitates quick changes in the rotation direction and ensures a good power source for testing.
[0031] Furthermore, the mounting assembly 105 includes a mounting plate 105a fixedly connected to the side wall of the support frame 104, and a limiting post 105b fixedly connected to the side wall of the mounting plate 105a. The mounting assembly 105 also includes a support plate 105c sleeved on the surface of the limiting post 105b, and a mounting base 105d fixedly connected to the side wall of the support plate 105c. The mounting assembly 105 also includes a counting display 105e fixedly connected to the side wall of the mounting plate 105a, and a control switch 105f electrically connected to the side wall of the counting display 105e.
[0032] The limiting post 105b is designed to increase the height of the support plate 105c. The surface of the support plate 105c is provided with dense holes, which allows debris generated by damping friction to fall through the holes during rotation testing and land on the surface of the mounting plate 105a, ensuring the cleanliness of the support plate 105c and facilitating the collection of debris.
[0033] Preferably, the mounting assembly 105 further includes a counting display 105e fixedly connected to the side wall of the mounting plate 105a, and a control switch 105f electrically connected to the side wall of the counting display 105e. The counting assembly 106 further includes a drive shaft 106c connected to the inner wall of the limit seat 106a via a bearing, and a drive bar 106d fixedly connected to the side wall of the drive shaft 106c. The counting assembly 106 also includes a connecting plate 106e fixedly connected to the side wall of the drive bar 106d, and a counter 106f fixedly connected to the side wall of the connecting plate 106e.
[0034] It should be noted that the counting display 105e uses the Advantech FDS-132-53V2N model display 105e, which has an IP65 protection rating, good optical display technology and high industrial-grade durability, and combines sealing, clarity and integration convenience.
[0035] In use, adjust the device to a comfortable height for the tester by moving the adjusting nut 102, fix the rotating shaft on the mounting base 105d, and start the device by controlling the switch 105f. The drive motor 107b will run, and the drive motor 107b will drive the drive rod 107c to perform a circular motion with the output end of the drive motor 107b as the axis. The drive rod 107c drives the transmission shaft 106c to rotate through the connecting assembly 108. The transmission shaft 106c drives the transmission bar 106d to perform a synchronous circular motion. The transmission bar 106d drives the counter 106f on the connecting plate 106e to move. When the counter 106f moves, it will touch the protrusion 106b. Each time it touches the protrusion 106b, it will count once. After the test is completed, the display 105e will display the counting result of the counter 106f.
[0036] In summary, the two sets of adjusting nuts 102 work together to easily adjust the height of the device and securely lock the position, adapting to the needs of different operators. The servo motor drive ensures smooth power output and fast steering switching, guaranteeing continuity during the testing process. The dense perforations on the surface of the support plate 105c effectively guide the debris generated by friction, maintaining the cleanliness of the working area and facilitating subsequent cleaning, thus enhancing the durability and maintainability of the equipment. The high-protection-level counting display 105e, combined with the mechanical counting mechanism, achieves accurate test data and facilitates clear presentation of results, providing reliable data for the evaluation of shaft damping life. Example 2
[0037] Reference Figures 1-2 This is the second embodiment of the present invention, which differs from the first embodiment in that it provides a modular and detachable structural connection component 108 that facilitates the connection between the drive component 107 and the counting component 106.
[0038] Furthermore, the connecting assembly 108 includes a connecting rod 108a fixedly connected to the end of the drive shaft 106c, and a slot 108b disposed on the surface of the connecting rod 108a. The connecting assembly 108 also includes a crossbeam 108c snapped into the inner wall of the slot 108b, and a slot 108d disposed on the surface of the crossbeam 108c. The connecting assembly 108 also includes a connecting block 108e inserted into the inner wall of the slot 108d, and a clamping groove 108f disposed on the surface of the connecting block 108e.
[0039] Furthermore, the end of the crossbeam 108c engages with the connecting groove 107d on the surface of the drive rod 107c. The crossbeam 108c facilitates the connection of the connecting rod 108a and the drive rod 107c, ensuring that the drive rod 107c and the connecting rod 108a operate synchronously. The connecting block 108e facilitates the connection with the rotating shaft, ensuring that the rotating shaft can be driven when the drive assembly 107 is running, thus ensuring the accuracy of the device's test results.
[0040] In use, the side wall of the rotating shaft is inserted into the clamping groove 108f, the connecting block 108e is inserted into the slot 108d on the surface of the crossbeam 108c, and the two ends of the crossbeam 108c are respectively inserted into the connecting groove 107d and the slot 108b. When the drive assembly 107 is running, the drive rod 107c will drive the crossbeam 108c to move, the crossbeam 108c will drive the connecting block 108e to move, and the connecting block 108e will drive the rotating shaft to rotate through the clamping groove 108f, ensuring that the rotating shaft moves synchronously with the direction of the drive motor 107b.
[0041] In summary, through the modular snap-fit and plug-in structure, the connecting component 108 enables quick assembly and disassembly and reliable connection between the drive component and the test shaft. This not only adapts to the testing requirements of shafts of different specifications, greatly improving the versatility of the equipment, but also ensures the synchronization and stability of power transmission, thereby effectively guaranteeing the accuracy and repeatability of test data.
