Description

Technical Field

[0001] This utility model relates to the field of vibration damper testing technology, and in particular to a vibration damper vibration performance testing device. Background Technology

[0002] Shock absorbers are an indispensable and important component of motor vehicles. Their main function is to reduce and absorb the impact and vibration transmitted to the wheels due to uneven road surfaces. They control the vertical vibration of the suspension by providing damping, thereby ensuring the smoothness and comfort of the ride.

[0003] Existing vibration damping performance testing devices can only perform fixed tests on a single set of vibration dampers during installation and use. However, when sampling vibration dampers for testing, multiple samples often need to be taken, requiring users to conduct multiple tests to complete the sampling inspection. This results in excessively long testing times, reduced user efficiency, and negatively impacts the user experience. To address the shortcomings of existing technologies, we propose a vibration damping performance testing device. Utility Model Content

[0004] The main purpose of this invention is to provide a vibration damping performance testing device for a vibration damper, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vibration damping performance testing device for a vibration damper includes a workbench. Three sets of fixed plates are symmetrically arranged on the upper end of the workbench. A first fixed ring is located on one side of each fixed plate, and a second fixed ring is located below the first fixed ring. The first and second fixed rings are symmetrically arranged and have the same specifications. A silicone pad is placed between the first and second fixed rings.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the device can simultaneously test three sets of vibration dampers from the same production batch by means of a balance plate and a fixing plate. The balance plate controls the pressure on each set of vibration dampers, ensuring that the pressure on each set of vibration dampers is consistent. At the same time, the pressure sensor can display the force on the vibration damper. Combined with the time it takes for the vibration damper to stop rebound after being subjected to force, the vibration damping performance of the vibration damper can be reflected, reducing the time required for users to conduct random inspections and tests on the vibration dampers.

[0014] In this invention, the first and second fixing rings and other structures enable the device to fix shock absorber bodies of different sizes with good fixing effect, thereby increasing the range of applications of the device and effectively enhancing its practicality.

[0020] 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.

[0021] like Figures 1-4 As shown, a vibration damping performance testing device for a vibration damper includes a controller installed inside the workbench 1. A wire is connected between the controller, the pressure sensor 5, and the cylinder 2. The pressure sensor 5 and the cylinder 2 are electrically connected to the controller via the wire. The outer wall of the limiting rod 7 is smooth. A smooth round hole is provided between the first fixing ring 10 and the connecting rod 11. The connecting rod 11 and the first fixing ring 10 are movably connected through the smooth round hole. The connecting rod 11 is threadedly connected to the nut 13. The second fixing ring 17 is welded to the fixing plate 16. The connecting rod 11 and the second fixing ring 17 are also welded together.

[0022] like Figures 1-4 As shown, a total of three sets of cylinders 2, six sets of limit rods 7, and three sets of fixing plates 16 are provided. The two ends of the limit rods 7 are respectively welded to the slide plate 3 connected to the fixing plate 16 and the worktable 1 or the slide plate 3 connected to the worktable 1. The balance plate 6 has four sets of smooth holes inside. The limit rods 7 are movably connected to the balance plate 6 through the smooth holes. The slide plate 3 connected to the abutment plate 8 or the balance plate 6 is provided with a circular hole between it and the limit rod 7. The slide plate 3 connected to the abutment plate 8 or the balance plate 6 is movably connected to the limit rod 7 through the circular hole. A total of sixteen sets of slide plates 3 are provided.

[0023] It should be noted that this utility model is a vibration damping performance testing device for a vibration damper. When in use, the user places multiple sets of vibration damper bodies 9 onto the second fixing ring 17 in sequence, and then hooks the hook 12 into the other end of the vibration damper body 9 so that the end face of the vibration damper body 9 abuts against the silicone pad 15. At the same time, the first fixing ring 10 rests against the upper end of the vibration damper body 9 due to gravity. By rotating the nut 13, the first fixing ring 10 is made to fit tightly against the vibration damper body 9. The first fixing ring 10 and the second fixing ring 17 fix the vibration damper body 9.

[0024] After the fixation is completed, cylinder 2 drives the balance plate 6 forward, causing the pressure column 4 and pressure sensor 5 to press against the stop plate 8. The stop plate 8 is driven forward to press the shock absorber body 9, and the data on the pressure sensor 5 is recorded. Cylinder 2 drives the pressure column 4 and pressure sensor 5 to retract, causing the shock absorber body 9 to lose the force of resistance. The right end of the shock absorber body 9 begins to move left and right until it stops. The user tests the shock absorber's damping performance by recording the time it takes for each set of shock absorber bodies 9 to stop.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
