Abstract
Description
Technical Field
[0001] This utility model relates to the field of waveform spring compression testing technology, and in particular to a device for waveform spring compression testing. Background Technology
[0002] Wave springs are a special type of spring with a wave-like shape. Compared to ordinary helical compression springs, wave springs can reduce their height by 50% under the same load. Wave spring compression testing is a crucial step in evaluating wave spring performance. The main purpose of this test is to measure the spring force at different compression levels to ensure it meets design requirements and usage standards. This test assesses the wave spring's load-bearing capacity, deformation characteristics, and service life. During wave spring compression testing, there is a certain probability that the wave spring will be affected by external forces and move horizontally. This can prevent the spring from being properly compressed, thus affecting the test process. Furthermore, traditional wave spring compression testing equipment lacks spring measuring components, often requiring external equipment (such as vernier calipers) to measure the spring's recovery capacity at different compression levels. This measurement method is inefficient. Therefore, a device for wave spring compression testing is needed to solve these problems. Utility Model Content

[0018] 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.
[0019] Please see Figure 1 - Figure 4 As shown, an apparatus for wave spring compression testing includes a bottom support 1. A longitudinal drive gantry 2 is fixedly mounted on the upper end of the bottom support 1. A movable plate 3 is mounted on the longitudinal drive gantry 2. A compression assembly 4 is fixedly mounted on the movable plate 3. The compression assembly 4 consists of a connecting rod 8 and a compression plate 9. The compression plate 9 has three notches 10. A support assembly 5 is fixedly mounted on the upper end of the bottom support 1 and below the compression assembly 4. Three adjusting assemblies 6 are rotatably mounted on the support assembly 5. A limit measuring assembly 7 is mounted on the adjusting assemblies 6. The limit measuring assembly 7 consists of a base block 19 and a baffle 21. The baffle 21 is fixedly mounted on the upper end of the base block 19. A scale 22 is provided on the outer end of the baffle 21. During wave spring compression testing... During the compression test, the wave spring can be placed on the support assembly 5, making the wave spring coaxial with the support assembly 5 and the compression assembly 4. Then, the limit measuring assembly 7 is moved and adjusted by rotating the adjustment assembly 6, so that the limit measuring assembly 7 is close to the wave spring, thereby limiting and blocking the wave spring. Finally, the longitudinal drive gantry 2 can be started, so that the moving plate 3 moves downward with the compression assembly 4, and finally the compression plate 9 compresses the wave spring. At this time, the compression plate 9 will be fitted onto the three baffles 21 through the notch 10. After the compression of the wave spring is completed, the moving plate 3 can be moved upward with the compression assembly 4 to reset. Then, the recovery ability of the wave spring can be observed directly through the scale 22 on the baffle 21.
[0020] Finally, by setting the limit measuring component 7, the adjustment component 6, and the support component 5, wave springs of different diameters can be limited and blocked. This prevents the wave springs from moving horizontally during the test, thus ensuring the smooth progress of the wave spring compression test. At the same time, when measuring the recovery ability of the wave spring under different compression degrees, the recovery ability of the wave spring can be directly observed through the scale 22 on the baffle 21 without the need for external equipment, thereby improving the measurement efficiency. By setting the compression component 4, which consists of the connecting rod 8 and the compression plate 9, and setting the notch 10 on the compression plate 9, compression tests can be performed on wave springs of different diameters.
[0021] Specifically, the connecting rod 8 on the extrusion assembly 4 is fixedly installed on the moving plate 3, and the extrusion plate 9 is fixedly installed on the lower end of the connecting rod 8. When the extrusion assembly 4 moves downward to compress the wave spring, the extrusion plate 9 will be sleeved on the three baffles 21 on the three limit measuring assemblies 7 through the notch 10.
[0022] Specifically, the support assembly 5 consists of a placement platform 12 and a support frame 11. The support frame 11 is fixedly installed at the lower end of the placement platform 12 and at the upper end of the bottom bracket 1. Three guide rail grooves 13 are provided on the upper end of the placement platform 12 of the support assembly 5, arranged in a ring. Three through holes 15 are provided on the outer wall of the placement platform 12, communicating with the guide rail grooves 13. Blind holes 14 are provided on the inner wall of the guide rail grooves 13. The adjustment assembly 6 consists of a lead screw 16, a handle 17, and a retaining ring 18. The handle 17 is fixedly installed on the outer end of the lead screw 16, and the retaining ring 18 is fixedly sleeved on the lead screw 16. The lead screw 16 is rotatably installed in the blind holes 14, guide rail grooves 13, and through holes 15. The retaining ring 18 is located in the guide rail groove 13, and the handle 17 is... On the outer side of the placement platform 12, the base block 19 on the limit measuring component 7 is slidably installed in the guide rail groove 13, and the base block 19 is located inside the retaining ring 18. The base block 19 has a threaded hole 20, and the base block 19 is installed on the lead screw 16 through the threaded hole 20. When it is necessary to move and adjust the limit measuring component 7, the lead screw 16 can be rotated by the handle 17. At this time, the limit measuring component 7 will move on the lead screw 16. When the position of the limit measuring component 7 is appropriate, the rotation of the lead screw 16 can be stopped. When observing the recovery ability of the wave spring, the scale 22 corresponding to the uppermost end before the wave spring is compressed can be observed first, and then the scale 22 corresponding to the uppermost end after the wave spring is compressed and recovered can be observed. By comparing the two height values of the wave spring, the recovery ability of the wave spring can be obtained.
