Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material fatigue testing, in particular to the appearance of an electronic fatigue testing machine. Background Art
[0002] Electronic fatigue testing is a testing method used to evaluate the durability of materials and structures under repeated loading. This kind of test is usually carried out by an electronic fatigue testing machine. Its basic principle is to repeatedly load the sample under controlled loading conditions to simulate the continuous load that it may suffer during actual use. The appearance of an electronic fatigue testing machine is usually designed with a stable structure, a user-friendly operation interface, and is equipped with an advanced control and data acquisition system to achieve high-precision and high-efficiency fatigue testing. Its appearance and size will vary according to specific test requirements and the model of the testing machine.
[0003] The appearance of a traditional electronic fatigue testing machine consists of parts such as a frame structure, a control console, and a loading system. The rotational motion of the motor is converted into the linear motion of the test sample through a transmission system.

The control system adjusts and controls the test process in real time according to the data obtained from sensors and measuring devices in real time, such as the loading force, displacement, and deformation, to ensure the accuracy and repeatability of the test. Finally, the data acquisition system records the data obtained in real time and can perform data analysis and processing.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] Refer to Figure 1 Figure 2 and Figure 3 As shown in [drawings not specified in the original text], an embodiment provided by the present invention: the outer shape of an electronic fatigue testing machine includes a workbench 1. A mounting plate 7 is fixedly connected to the upper surface of the workbench 1. A fixed strip 8 is fixedly connected to the upper surface of the mounting plate 7. A slide block 9 is slidably connected to the side wall of the fixed strip 8. A first fixing plate 10 is fixedly connected to the upper surface of the slide block 9. A clamping plate 11 is fixedly connected to the upper surface of the first fixing plate 10. An auxiliary component is provided on the side wall of the clamping plate 11 to protect the test piece. A second hydraulic rod 13 is fixedly connected to the upper surface of the mounting plate 7. The output end of the second hydraulic rod 13 is fixedly connected to a first fixing block 14. The upper surface of the first fixing block 14 is fixedly connected to the lower surface of the right first fixing plate 10. A placing plate 16 is fixedly connected to the upper surface of the fixed strip 8. A rack 15 is fixedly connected to the lower surface of the first fixing plate 10. A first gear 17 is rotatably connected to the upper surface of the mounting plate 7. The first gear 17 meshes with the rack 15. The auxiliary component includes a rubber pad 12. The side wall of the rubber pad 12 is fixedly connected to the side wall of the clamping plate 11. Support columns 2 are fixedly connected to the upper surface of the workbench 1. The upper ends of the support columns 2 are fixedly connected to a top plate 3. A detector 4 is fixedly connected to the upper surface of the top plate 3. A first hydraulic rod 5 is fixedly connected to the lower surface of the top plate 3. The output end of the first hydraulic rod 5 is fixedly connected to a controller 6;
[0033] During the fatigue test operation of the device, when it is necessary to firmly clamp the test piece, the operator will first activate the second hydraulic rod 13. Through this action, the second hydraulic rod 13 will transmit the force to the first fixing block 14, thereby pushing the first fixing plate 10 on the right side of the device to smoothly slide along the guide rail. As the fixing plate slides, the slider 9 moves parallelly on the side wall of the fixing bar 8, creating conditions for clamping the test piece. Next, through the meshing mechanism between the first gear 17 and the rack 15, the operator can drive the left rack 15, enabling the left first fixing plate 10 to also slide along the established trajectory. After this series of actions are completed, the clamping plate 11 will approach the side wall of the test piece.
[0034] Refer to Figure 1 and Figure 4 , a bottom plate 18 is fixedly connected to the lower surface of the workbench 1. A fixing frame 19 is fixedly connected inside the bottom plate 18. A roller 27 is arranged on the lower surface of the fixing frame 19. A bottom column 28 is fixedly connected to the lower surface of the bottom plate 18. A screw rod 20 is rotatably connected inside the bottom plate 18. A lifting frame 25 is threadedly connected to the side wall of the screw rod 20. One end of the screw rod 20 penetrates through the bottom plate 18 and is fixedly connected to a second gear 21. A chain 24 is arranged between the second gears 21. A second fixing plate 22 is fixedly connected to the upper surface of one fixing frame 19. A motor 23 is fixedly connected to the lower surface of the second fixing plate 22. The output end of the motor 23 is fixedly connected to the side wall of one fixing frame 19. The side wall of the lifting frame 25 is slidably connected inside the bottom plate 18. A third fixing plate 26 is fixedly connected to the lower surface of the lifting frame 25. The lower surface of the third fixing plate 26 is fixedly connected to the upper surface of the roller 27.
[0035] When it is necessary to adjust the position of the device, it is first necessary to turn on the device. At this time, the motor 23 is started, causing the motor 23 to start working. The operation of the motor 23 drives the second gear 21 connected to the output end to start rotating. The rotation of the second gear 21 is transmitted through the chain 24. The chain 24 evenly transmits the power to the second gears 21 around, causing all the second gears 21 to start rotating. The rotation of the second gear 21 further drives the screw rod 20 to start rotating inside the bottom plate 18. As the screw rod 20 rotates, the lifting frame 25 starts to move downward under the action of the side wall of the screw rod 20. The movement of the lifting frame 25 drives the roller 27 to start sliding down. This process continues until the lifting frame 25 completely jacks up the device. When the device is completely jacked up, the staff can start working and push the device to move.
[0036] Working principle: When using this device for fatigue tests and clamping the test piece, first start the second hydraulic rod 13, which pushes the right fixed plate 10 to slide through the first fixed block 14, causing the slider 9 to slide on the side wall of the fixed strip 8. Then, due to the meshing relationship between the first gear 17 and the rack 15, the left rack 15 is pushed, driving the left fixed plate 10 to slide, and further making the clamping plate 11 slowly approach the side wall of the test piece to fix it. When the device needs to be moved, start the motor 23, which drives the second gear 21 connected to its output end to rotate. Subsequently, the second gears 21 around are driven to rotate through the chain 24, further driving the screw 20 to rotate inside the bottom plate 18, so that the lifting frame 25 moves downward on the side wall of the screw 20, and then drives the rollers 27 to slide down until the device is lifted. Then the staff can push the device to move.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
