Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically a testing device for the assembly firmness of irregular fasteners. Background Technology

[0002] Non-standard fasteners are those that deviate from national standards and are customized to meet specific needs. They differ from ordinary standard fasteners in shape, size, material, or performance, and are characterized by strong customization and application specificity. They come in a wide variety of types, categorized by shape into special forms such as U-shape, L-shape, T-shape, and hook shape, as well as those with special structures such as steps and knurling; by function into categories such as connection, locking, and positioning; and by manufacturing process, encompassing cold heading, hot forging, precision casting, sheet metal forming, and more. Common specific products include non-standard bolts, non-standard nuts, special threaded fasteners, and non-standard retaining nuts. These fasteners can adapt to special working conditions; for example, non-standard bolts can fit tightly to the connection part to improve the reliability of the fastening, while non-standard retaining nuts, with their snap-fit ​​design, enable quick installation and secure connection in confined spaces. They are widely used in many key fields. In the field of electronic equipment, they are used to meet the special layout requirements of components by adapting to compact space. In the field of automotive manufacturing, they are used to cope with different installation environments and vibration and shock resistance requirements. In the field of aerospace, they rely on their high strength and low density characteristics to ensure the reliability and safety of components. In the field of furniture manufacturing, they achieve the dual effects of aesthetics and convenient assembly through their concealed installation, becoming an important support for the special connection and fastening needs of various industries.

[0003] This application improves upon the existing technology. In the existing technology, when testing the anti-loosening performance of irregular fasteners, vibration test benches are often used to simulate working condition vibrations to check whether the assembled irregular fasteners have loosened or shifted. However, the existing vibration test benches lack an effective classification structure, which causes many assembled fasteners to collide together during testing, thus affecting the accuracy of the test and resulting in poor test results.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a device for testing the assembly firmness of irregular fasteners. This solves the problem in the prior art where existing methods for testing the anti-loosening performance of irregular fasteners often involve using a vibration test bench to simulate working conditions and inspect the assembled irregular fasteners for loosening or displacement. However, existing vibration test benches lack an effective classification structure, causing many assembled fasteners to collide during testing, thus affecting the accuracy of the test and resulting in poor testing results.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A device for testing the assembly firmness of irregular fasteners includes a base, a placement plate movably mounted on the top of the base, damping shock absorbers fixedly connected to both sides of the bottom of the placement plate, a vibration motor installed at the center of the bottom of the placement plate, placement grooves symmetrically formed on the upper surface of the placement plate, placement blocks movably mounted inside the placement grooves, fixing holes formed on the outer walls of the two placement blocks on their opposite sides, and a placement frame fixedly connected to the top of the placement blocks; and a protective component disposed inside the placement frame, the protective component including symmetrically formed rectangular placement grooves on the upper surface of the placement frame, circular placement grooves formed at the top of the placement frame at the ends of the two rectangular placement grooves that are close to each other, positioning holes formed at the four corners of the top of the placement frame, positioning rods movably mounted inside the positioning holes, a cover plate fixedly connected to the top of the positioning rods, and a pull block fixedly connected to the top of the cover plate.

Fixed rods are fixedly connected to the sides of the two movable plates that are close to each other, and one end of the fixed rod is movably arranged inside the fixed hole.

[0008] Preferably, each of the two movable plates is fixedly connected to a pull rod on the side away from each other, and a spring is sleeved on the outer wall of the pull rod. Each of the two pull rods is fixedly connected to a pull ring on the side away from each other.

[0009] Preferably, the upper surface of the base is provided with a plurality of limiting holes, and a limiting rod is movably disposed inside the limiting holes, and the top end of the limiting rod is fixedly connected to the bottom of the placement plate.

[0010] Preferably, two grooves are formed on the right side of the limiting hole at the top of the base, and a storage frame is movably arranged inside the grooves, with fixing blocks fixedly connected to both ends of the storage frame.

[0011] Preferably, support blocks are fixedly connected to the four corners of the bottom of the base, and a control panel is fixedly installed on the front end of the base.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are: 1.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6 The device for testing the assembly firmness of irregular fasteners includes a base 5, a placement plate 3 is movably arranged on the top of the base 5, damping shock absorbers 4 are fixedly connected to both sides of the bottom of the placement plate 3, a vibration motor 7 is installed at the center of the bottom of the placement plate 3, placement grooves 14 are symmetrically opened on the upper surface of the placement plate 3, placement blocks 18 are movably arranged inside the placement grooves 14, fixing holes 17 are opened on the outer walls of the two placement blocks 18 on the side away from each other, and a placement frame 2 is fixedly connected to the top of the placement blocks 18. The protective component is set inside the placement frame 2. The protective component includes rectangular grooves 16 symmetrically opened on the upper surface of the placement frame 2. A circular groove 12 is opened at the top of the two rectangular grooves 16 that are close to each other. Positioning holes 13 are opened at the four corners of the top of the placement frame 2. Positioning rods 15 are movably arranged inside the positioning holes 13. A cover plate 1 is fixedly connected to the top of the positioning rod 15. A pull block 6 is fixedly connected to the top of the cover plate 1. Multiple limiting holes 20 are opened on the upper surface of the base 5. Limiting rods 19 are movably arranged inside the limiting holes 20, and the top of the limiting rods 19 is fixedly connected to the bottom of the placement plate 3. Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, during use, the interaction of multiple circular slots 12 and rectangular slots 16 facilitates the classification and placement of assembled irregular fasteners, preventing collisions during later testing and thus improving testing accuracy and effectiveness. Simultaneously, by inserting the positioning rod 15 on the cover plate 1 into the positioning hole 13 on the placement frame 2, the circular slots 12 and rectangular slots 16 can be sealed, preventing them from detaching from the placement frame 2 during subsequent vibration testing, thereby improving safety during the testing process. Furthermore, when vibration is required on the irregular fasteners within the circular slots 12 and rectangular slots 16, vibration is generated by the vibration motor 7, facilitating the vibration of the irregular fasteners within the circular slots 12 and rectangular slots 16. The vibration of the fastener is reduced by the damping shock absorber 4, which reduces noise and vibration, thus protecting the stability and safety of the device. The limit rod 19 and the limit hole 20 limit the vertical movement of the placement plate 3, further improving the safety of the placement plate 3 when vibrating vertically. This solves the problem that existing vibration test benches are often used to simulate working conditions and check the assembled fasteners for loosening or displacement when testing the anti-loosening performance of irregular fasteners. However, the existing vibration test benches lack an effective classification structure, which causes many assembled fasteners to collide during testing, affecting the accuracy of the test and resulting in poor test results.

[0018] Sleeves 22 are fixedly connected to both outer walls of the placement plate 3. Movable plates 26 are movably arranged inside the sleeves 22. Fixed rods 25 are fixedly connected to the side of the two movable plates 26 that are close to each other, and one end of the fixed rods 25 is movably arranged inside the fixed hole 17. Pull rods 24 are fixedly connected to the side of the two movable plates 26 that are far apart from each other. Springs 27 are sleeved on the outer wall of the pull rods 24. Pull rings 23 are fixedly connected to the side of the two pull rods 24 that are far apart from each other. Two grooves 21 are opened on the right side of the limiting hole 20 at the top of the base 5. Storage frames 10 are movably arranged inside the grooves 21. Fixed blocks 11 are fixedly connected to both ends of the storage frames 10. Support blocks 9 are fixedly connected to the four corners of the bottom of the base 5. A control panel 8 is fixedly installed on the front end of the base 5. Specifically, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when it is necessary to disassemble the placement frame 2 and the placement plate 3, the two pull rings 23 can be pulled in opposite directions. The pull rings 23 move and eventually cause the fixing rod 25 to disengage from the fixing hole 17. Then, the placement frame 2 is moved upward until the placement block 18 disengages from the placement groove 14, thus completing the disassembly of the placement frame 2 and the placement plate 3. Similarly, the placement frame 2 and the placement plate 3 can be assembled. By facilitating the disassembly and assembly of the placement frame 2 and the placement plate 3, it is convenient to place the irregular fasteners to be tested and to observe the irregular fasteners after vibration, thereby improving the testing efficiency. At the same time, the setting of the two storage boxes 10 facilitates the classification and placement of irregular fasteners, which is convenient for the staff to organize them uniformly later, thereby improving the work efficiency of the staff.

[0019] Working Principle: In this application, the cooperation of multiple circular slots 12 and rectangular slots 16 facilitates the classification and placement of assembled irregular fasteners, preventing collisions during later testing and thus improving the accuracy and effectiveness of the inspection. Simultaneously, by inserting the positioning rod 15 on the cover plate 1 into the positioning hole 13 on the placement frame 2, the circular slots 12 and rectangular slots 16 can be sealed, preventing them from detaching from the placement frame 2 during vibration testing, thereby improving safety during the inspection process. Furthermore, when vibration is required on the irregular fasteners within the circular slots 12 and rectangular slots 16, vibration is generated by the vibration motor 7, facilitating the shaking of the fasteners. The damping shock absorber 4 reduces noise and vibration. Firstly, the placement frame 2 and placement plate 3 are designed to protect the stability and safety of the device. Secondly, when it is necessary to disassemble the placement frame 2 and placement plate 3, the two pull rings 23 can be pulled in opposite directions. The pull rings 23 move and eventually cause the fixing rod 25 to disengage from the fixing hole 17. Then, the placement frame 2 is moved upward until the placement block 18 disengages from the placement groove 14, thus completing the disassembly of the placement frame 2 and placement plate 3. Similarly, the placement frame 2 and placement plate 3 can be assembled. By facilitating the disassembly and assembly of the placement frame 2 and placement plate 3, it is convenient to place the irregular fasteners to be tested and to observe the irregular fasteners after vibration, thereby improving the efficiency of the test. Finally, the setting of two storage boxes 10 facilitates the classification and placement of irregular fasteners, which is convenient for the staff to organize them uniformly later, thereby improving the work efficiency of the staff.
