Technical Field

[0001] This utility model relates to the field of testing and detection technology, specifically to a nut anti-loosening experimental device. Background Technology

[0002] In fields such as machinery manufacturing, automotive industry, aerospace, and construction engineering, nuts are core fastening components, and their anti-loosening performance is directly related to the operational safety and service life of equipment.

[0003] The device consists of a working condition simulation module, a load application unit, a data acquisition system, a fixing and clamping mechanism, and an intelligent control system. The operator selects the nut specification and experimental working conditions, sets the preload and experimental duration, and the device automatically completes working condition simulation, data acquisition and analysis after starting the equipment, without the need for manual intervention.

[0004] However, the above-mentioned equipment has certain shortcomings in use. The screw of the traditional device is fixedly connected to the experimental platform. When changing screws of different diameters, multiple sets of parts need to be disassembled, which takes too long and cannot meet the needs of batch multi-specification testing. In view of this, we propose a nut anti-loosening experimental device. Utility Model Content

[0005] The purpose of this invention is to provide a nut anti-loosening test device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A nut anti-loosening test device includes a workbench, on which control buttons and a display panel are provided. A testing component is also provided on the workbench, the testing component comprising: A mounting plate is snapped onto the workbench. A rubber box is fixedly mounted on the mounting plate. A buffer pad is fixedly mounted on the rubber box. A spring rod is fixedly mounted between the buffer pad and the inner wall of the workbench. A rubber pad is fixedly installed at the bottom of the rubber box. An installation block is fixedly installed inside the rubber box. A vibration motor is fixedly installed at the bottom of the installation block. A snap-fit ​​box is fixedly installed above the installation block. A snap-fit ​​block is snap-fitted inside the snap-fit ​​box. A screw is fixedly mounted on the snap-fit ​​block. A hydraulic device is fixedly mounted inside the workbench. An annular plate is fixedly mounted on the piston end of the hydraulic device. A test sensor is fixedly mounted on the annular plate.

[0007] In a further embodiment, multiple sets of the buffer pad, spring rod, rubber pad, hydraulic equipment, and test sensor are provided.

[0008] In a further embodiment, a test block is fitted onto the snap-fit ​​box, a test nut is threaded onto the screw, the test nut is positioned above the test block, and an anti-slip washer is provided between the test nut and the test block.

[0009] In a further embodiment, the test block, test nut, and anti-slip washer are positioned between multiple sets of test sensors, and the rubber pad is attached to the bottom inner side of the workbench.

[0010] In a further embodiment, the mounting block is provided with an auxiliary component, the auxiliary component including a positioning hole, the positioning hole being formed on the snap-fit ​​block, the mounting block having a mounting groove, one end of a helical spring being fixedly installed inside the mounting block, and the other end of the helical spring being fixedly installed with a positioning block.

[0011] In a further embodiment, multiple sets of positioning holes, mounting slots, helical springs, and positioning blocks are provided.

[0012] In a further embodiment, the helical spring is disposed inside the mounting groove, the positioning block slides inside the mounting groove, and multiple sets of the positioning blocks correspond to multiple sets of positioning holes.

[0013] Compared with the prior art, this utility model provides a nut anti-loosening test device, which has the following beneficial effects: 1. This nut anti-loosening test device is designed to meet the performance testing requirements of batch anti-loosening nuts. It incorporates a test component that, in conjunction with a vibration motor, drives the snap-fit ​​box and screw to vibrate at high frequency, simulating the vibration environment of nuts in actual use. A hydraulic device pushes a ring plate and test sensors to observe the test nut, collecting real-time data on nut loosening displacement and torque changes, which is then transmitted to a display panel for intuitive presentation. The rubber box, buffer pad, and spring rod form a triple buffer structure to absorb the impact force generated by vibration and prevent equipment damage.

[0014] 2. To adapt the nut anti-loosening test device to the requirements of high-precision and multi-specification anti-loosening performance tests, an auxiliary component is set up. This component, together with a helical spring, pushes the ball head positioning block into the positioning hole of the snap-fit ​​block. The ball head design reduces contact friction, and the snap-fit ​​block can be directly inserted and removed without pressing. In vibration tests, the snap-fit ​​block and the screw can be kept stable by elastic clamping. By directly inserting and removing snap-fit ​​blocks with screws of different diameters, the nut anti-loosening test corresponding to various screw specifications can be quickly switched without readjusting the test device.

[0019] Please see Figures 1-7 This utility model provides a technical solution: A nut anti-loosening test device includes a workbench 1, on which control buttons 2 and a display panel 3 are provided.

[0020] In one embodiment of this utility model, a test component 4 is provided on the workbench 1. The test component 4 includes a mounting plate 41, which is snapped onto the workbench 1. A rubber box 42 is fixedly mounted on the mounting plate 41, and a buffer pad 43 is fixedly mounted on the rubber box 42. A spring rod 44 is fixedly mounted between the buffer pad 43 and the inner wall of the workbench 1. A rubber pad 45 is fixedly mounted on the bottom of the rubber box 42. A mounting block 46 is fixedly mounted inside the rubber box 42. A vibration motor 47 is fixedly mounted on the bottom of the mounting block 46. A snap-fit ​​box 48 is fixedly mounted above the mounting block 46. A snap-fit ​​block 49 is snapped onto the inside of the snap-fit ​​box 48. A screw 410 is fixedly mounted on the snap-fit ​​block 49. On the 9th, a hydraulic device 411 is fixedly installed inside the workbench 1. An annular plate 412 is fixedly installed on the piston end of the hydraulic device 411. A test sensor 413 is fixedly installed on the annular plate 412. Multiple sets of buffer pads 43, spring rods 44, rubber pads 45, hydraulic devices 411 and test sensors 413 are provided. A test block 5 is sleeved on the snap-fit ​​box 48. A test nut 6 is threaded on the screw 410. The test nut 6 is located above the test block 5. An anti-slip washer 7 is provided between the test nut 6 and the test block 5. The test block 5, the test nut 6 and the anti-slip washer 7 are arranged between multiple sets of test sensors 413. The rubber pad 45 is attached to the bottom inner side of the workbench 1.

[0021] In this embodiment, before the experiment, the test block 5 is placed on the snap-fit ​​box 48, and the anti-slip washer 7 and the test nut 6 are installed and tightened on the screw 410 in sequence to simulate the actual installation scenario. According to the test requirements, test blocks 5 and anti-slip washers of different specifications can be replaced to adapt to various working conditions. The equipment is started by controlling button 2, and the vibration motor 47 at the bottom of the mounting block 46 runs, driving the snap-fit ​​box 48, snap-fit ​​block 49 and screw 410 to vibrate at high frequency, accurately simulating the vibration environment of the nut in actual use. At the same time, multiple sets of hydraulic devices 411 inside the workbench 1 are started to push the annular plate 412 and the test sensor 413 close to the test nut 6, and collect data such as nut loosening displacement and torque change in real time. The data is transmitted to the display panel 3 for intuitive presentation, which is convenient for the experimenter to analyze the anti-loosening performance. The rubber box 42, buffer pad 43 and spring rod 44 form a triple buffer structure, which, together with the rubber pad 45, absorbs the impact force generated by vibration, avoids equipment damage due to high frequency vibration, and ensures experimental stability.

[0022] In one embodiment of this utility model, an auxiliary component 8 is provided on the mounting block 46. The auxiliary component 8 includes a positioning hole 81, which is opened on the snap-fit ​​block 49. The mounting block 46 is provided with a mounting groove 82. One end of a helical spring 83 is fixedly installed inside the mounting block 46, and a positioning block 84 is fixedly installed on the other end of the helical spring 83. Multiple sets of positioning holes 81, mounting grooves 82, helical springs 83, and positioning blocks 84 are provided. The helical springs 83 are disposed inside the mounting grooves 82, and the positioning blocks 84 slide inside the mounting grooves 82. The multiple sets of positioning blocks 84 correspond to the positions of multiple sets of positioning holes 81.

[0023] In this embodiment, when it is necessary to replace the screw 410 with a different specification, the snap-fit ​​block 49 can be directly inserted and removed: When the snap-fit ​​block 49 is inserted, the helical spring 83 in the mounting block 46 pushes the positioning block 84 into the positioning hole 81 of the snap-fit ​​block 49, realizing quick positioning and stable snap-fit. The ball head design of the positioning block 84 reduces contact friction and does not require additional pressing operation. During the vibration test, the elastic force of the helical spring 83 continuously presses the positioning block 84 to ensure the stability of the snap-fit ​​block 49 and the screw 410, and avoids the vibration causing displacement that affects the experimental accuracy. If it is necessary to change the specification, simply pull the snap-fit ​​block 49 outward, and the positioning block 84 will be compressed back into the mounting groove 82, so that the snap-fit ​​block 49 can be removed and replaced with a snap-fit ​​block 49 with a screw 410 of the corresponding diameter. There is no need to readjust the experimental device, which improves the testing efficiency.
