[0002] During the inspection of automotive suspension springs, static pressure testing is the primary means of detecting spring performance degradation. However, static pressure testing is infrequent, and static pressure equipment is relatively expensive, making it wasteful to purchase a separate unit. The company currently has a flap fatigue testing machine, but flap fatigue testing is not performed very frequently. Research has shown that it is possible to improve the test fixture and perform static pressure testing on the flap fatigue testing machine, thereby meeting the inspection requirements for automotive suspension springs while also saving costs. Therefore, an improved spring static pressure testing device has been proposed, which can perform both static pressure and flap fatigue testing. Summary of the Invention

When springs are only installed in the two lower groups of beating assemblies, the connecting rod and the middle and upper plates are driven downward by the hydraulic rod, so that a static pressure test can be performed on the springs.

[0029] Example: Please refer to Figures 1 to 4 :
[0030] The utility model proposes an improved spring static pressure experiment device, comprising: a support frame 1; a connecting rod 7 is installed on the support frame 1, two screw rods 2 are installed on the top plate of the support frame 1, and a support rod 101 is fixedly welded between the upper and lower plates of the support frame 1; the top end of the connecting rod 7 is fixedly connected to the middle upper plate 4; the top plate 3, the middle upper plate 4 and the lower bottom plate 5 are sleeved on the support rod 101; two groups of flapping components 6 are respectively installed on the upper and lower sides of the middle upper plate 4.
[0031] In the embodiment of the present disclosure, Figure 1 and Figure 2 As shown, a rectangular through hole is provided in the center of the bottom plate of the support frame 1, and the interior of the rectangular through hole is penetrated by a connecting rod 7. The bottom end of the connecting rod 7 is connected to a hydraulic rod. After the hydraulic rod is started by the external circuit control end, it drives the connecting rod 7 to move back and forth, and synchronously drives the middle upper plate 4 to move back and forth, and performs a slap fatigue test on the springs placed on the upper and lower sides of the middle upper plate 4. After the spring is placed under the middle upper plate 4, the connecting rod 7 is pulled down by the hydraulic rod, and a static pressure test can be performed on the spring. The two tests can be switched to improve the utilization rate of the spring fatigue testing machine and save costs at the same time.
[0032] In the embodiment of the present disclosure, Figure 2As shown, the screw rod 2 is engaged with the top plate 3, and the screw rod 2 is engaged with the top panel of the support frame 1. By rotating the screw rod 2, the installation height of the top plate 3 can be adjusted, thereby adjusting the initial position of the middle upper plate 4, which facilitates the disassembly and assembly of the spring, and can also adjust the intensity of the slapping fatigue test or the static pressure test. It can also be applied to test different types of springs.
[0033] In the embodiment of the present disclosure, Figure 3 As shown, a through hole 501 is provided inside the lower base plate 5, and the through hole 501 is consistent in position and size with the rectangular through hole inside the bottom panel of the support frame 1. Holes 502 are provided at the four corners of the lower base plate 5, and the inside of the hole 502 is clipped onto the support rod 101, and the lower base plate 5 is fixedly connected to the bottom panel of the support frame 1. The through hole 501 does not affect the up and down movement of the connecting rod 7, and at the same time provides an installation basis for the guide plate 8 below, so that the two sets of flapping components 6 below can achieve angle changes, ensuring that the flapping experiment can be carried out.
[0034] In the embodiment of the present disclosure, Figure 2 and Figure 4 As shown, the flapping assembly 6 includes a flapping swing plate 61 and a flapping mounting plate 62. The flapping swing plate 61 is connected to the flapping mounting plate 62 through an axis rotation. A pressure plate 6201 is installed on the inner side of the flapping mounting plate 62, and a pressure plate 6201 is also installed on the inner side of the flapping swing plate 61. A bracket 6101 is installed on the outer end face of the flapping swing plate 61. A track groove is provided on the guide plate 8. A roller is connected to the bracket 6101 through a bearing. The roller is clamped into the track groove on the guide plate 8. After the spring to be tested is clamped on the pressure plate 6201, the other end of the spring rests on the pressure plate 6201 on the flapping swing plate 61 of the same group. When the connecting rod 7 drives the middle and upper plates 4 to move back and forth, the springs in the upper and lower four groups of flapping assemblies 6 are subjected to a reciprocating flapping fatigue test. When only the two lower groups of flapping assemblies 6 are equipped with springs, the connecting rod 7 is driven downward by the hydraulic rod to drive the middle and upper plates 4 downward, and a static pressure test can be performed on the springs.
[0035] The working principle of this embodiment is as follows: First, after the spring to be tested is clamped on the pressure plate 6201, the other end of the spring rests on the pressure plate 6201 on the flapping swing plate 61 of the same group. When the connecting rod 7 drives the middle upper plate 4 to move back and forth, the springs in the upper and lower four groups of flapping assemblies 6 are subjected to a reciprocating flapping fatigue test;
[0036] Only when the springs are placed in the two groups of flapping assemblies 6 below, the connecting rod 7 is driven downward by the hydraulic rod to drive the middle upper plate 4 downward, and the static pressure test of the springs can be carried out.
