AI Technical Summary
Existing wave spring fatigue performance testing equipment is easily affected by external objects or debris falling in during the testing process, which affects the accuracy of the test results.
A fatigue performance testing device for wave springs was designed, comprising a connecting component, a sliding limiting component, and a protective component. The connecting component fixes the protective component together to form a cylindrical shape to protect the wave spring, preventing foreign objects from falling into the gaps of the wave spring and ensuring the accuracy of the wave spring. By setting the sliding limiting component, the wave spring under test can be blocked and protected, ensuring that the wave spring is within its gaps and ensuring its reliability. By setting the sliding limiting component, the wave spring under test can be kept within its gaps, reducing the probability of the wave spring being affected by accidents during the testing process.
This effectively avoids the risk of the wave spring being touched by foreign objects or debris falling into the gap during the test, improves the accuracy of the test results, and reduces the resistance of the moving protection component.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of wave spring fatigue performance testing technology, and in particular to a wave spring fatigue performance testing device. Background Technology
[0002] The main purpose of wave spring fatigue performance testing is to simulate the periodic stress changes that springs experience in actual working environments. Through repeated loading and unloading, the performance changes of the spring material under long-term cyclic stress are observed and recorded until fatigue failure occurs. This process primarily focuses on the spring's fatigue life, fatigue strength, and the initiation and propagation mechanisms of fatigue cracks. When testing wave springs using fatigue performance testing equipment, the springs need to be repeatedly compressed and stretched for a period of time. During this process, external objects can easily touch the tested wave spring, or debris can fall into the gaps of the tested spring, thus affecting the accuracy of the test results. Therefore, a wave spring fatigue performance testing device is needed to solve these problems. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a wave spring fatigue performance testing device includes a bottom housing 1. Two longitudinal drive components 2 are symmetrically fixedly installed on the upper end of the bottom housing 1. A transverse support plate 3 is fixedly installed on the upper end of the two longitudinal drive components 2. A movable plate 4 is installed on the two longitudinal drive components 2 and below the transverse support plate 3. Two connecting components 5 are slidably installed on the transverse support plate 3. The connecting components 5 consist of a mounting base plate 9, a first L-shaped connecting rod 10, and a fixed magnet 11. The first L-shaped connecting rod 10 is fixedly installed on the lower end of the mounting base plate 9, and the fixed magnet 11 is fixedly installed on the mounting base plate. At the inner end of 9, two sliding limit components 6 are slidably installed on the movable plate 4. The sliding limit component 6 consists of a second L-shaped connecting rod 12, a fixed shaft 13, and a rotating cylinder 14. There are two fixed shafts 13, which are symmetrically fixed at both ends of the second L-shaped connecting rod 12. There are two rotating cylinders 14, which are rotatably installed on the two fixed shafts 13 respectively. A protective component 17 is fixedly installed on the connecting component 5 and the sliding limit component 6. The protective component 17 consists of a bellows 15 and a rigid arc plate 16. There are two rigid arc plates 16, which are symmetrically fixed on the outer walls of the upper and lower sides of the bellows 15, providing lateral support. Two first guide rail grooves 7 are symmetrically formed on the plate 3. A first clamp mounting bracket 18 is fixedly installed on the transverse support plate 3 between the two first guide rail grooves 7. Two second guide rail grooves 8 are symmetrically formed on the movable plate 4. A second clamp mounting bracket 19 is fixedly installed on the movable plate 4 between the two second guide rail grooves 8. When performing fatigue performance testing on the wave spring, the clamps can be fixed on the first clamp mounting bracket 18 and the second clamp mounting bracket 19. Then, the wave spring to be tested is fixed on the first clamp mounting bracket 18 and the second clamp mounting bracket 19. Then, the protective component 17 is used to protect the wave spring. The spring is protected by a barrier. The method is to push the two connecting components 5 on the horizontal support plate 3. At this time, the two connecting components 5 will drive the two protective components 17 to move closer to each other, and the two protective components 17 will bring the two sliding limit components 6 closer to each other, so that the two connecting components 5 are fixed together. At this time, the two protective components 17 will form a cylindrical shape, and the wave spring is inside the cylinder. At this time, the wave spring is blocked and protected. Then, the test equipment is started. At this time, the moving plate 4 will move up and down on the longitudinal drive component 2, thereby repeatedly squeezing and stretching the wave spring.
[0021] By setting the connecting component 5, the sliding limit component 6, and the protective component 17, the wave spring under test can be blocked and protected, thereby preventing the wave spring from being touched by foreign objects or having debris fall into the gaps of the wave spring during testing. This reduces the probability of the wave spring being affected by accidents during testing and ultimately ensures the accuracy of the wave spring test results. The connecting component 5 can be used to assemble and fix the two protective components 17 together; the sliding limit component 6 can reduce the resistance when moving the protective components 17.
[0022] Specifically, the mounting base plate 9 and the fixed magnet 11 on the connecting component 5 are located at the upper end of the transverse support plate 3. The first L-shaped connecting rod 10 is slidably installed in the first guide rail groove 7. When the two connecting components 5 approach each other and finally come into contact, the two fixed magnets 11 on the two connecting components 5 will attract each other.
[0023] Specifically, the second L-shaped connecting rod 12 on the sliding limit assembly 6 is slidably installed in the second guide rail groove 8. The fixed shaft 13 and the rotating cylinder 14 are both located below the moving plate 4, and the rotating cylinder 14 is in contact with the lower end of the moving plate 4. The two protective assemblies 17 are located between the transverse support plate 3 and the moving plate 4, and the two protective assemblies 17 are located on both sides of the first clamp mounting frame 18 and the second clamp mounting frame 19, respectively. The upper rigid arc plate 16 is fixedly connected to the first L-shaped connecting rod 10, and the lower rigid arc plate 16 is fixedly connected to the second L-shaped connecting rod 12. When the protective assembly 17 moves with the sliding limit assembly 6, the rotating cylinder 14 on the sliding limit assembly 6 will rub against the lower end of the moving plate 4, and then the rotating cylinder 14 will rotate on the fixed shaft 13.
