Description

Technical Field

[0001] This invention relates to the field of spring performance testing technology, specifically to a performance testing device for air spring dampers. Background Technology

[0002] An air spring damper is a device that uses air as an elastic medium. It is commonly used in vehicle suspension systems to provide better ride comfort and load balance. The working principle of an air spring damper is to support the weight of the vehicle by compressing air, and the air pressure can be adjusted as needed to change the stiffness or height of the spring.

[0003] To ensure the basic functionality of the product, as well as to protect user safety and improve the overall system performance, it is necessary to conduct performance testing on the manufactured air spring vibration dampers. During the compression performance test of the air spring vibration dampers, insufficient limiting and fixing can lead to swaying or displacement during compression, affecting the test results. Furthermore, air spring vibration dampers are installed at different angles depending on different requirements, but most existing tests only test the air spring vibration dampers vertically, without testing compression at different tilt angles, thus failing to obtain comprehensive test results.

[0011] Preferably, the limiting clamping component includes a connecting block, which is vertically installed in the middle of the upper end face of the moving strip. Each of the opposite faces of the connecting block has a vertical groove, and each of the lower end faces of the vertical groove has a side spring installed. Each of the vertical grooves has a pressing strip slidably installed inside the vertical groove. The upper end of the side spring is connected to the pressing strip. Each of the opposite faces of the pressing strip has a clamping block installed. Both pressing strips are connected to the limiting slide.

[0012] Preferably, the clamping ends of the abutment plate, clamping block, and clamping block are all arc-shaped structures, and the size of the abutment plate, clamping block, and clamping block gradually decreases from bottom to top.

[0013] Preferably, the limiting mounting plate is a disc structure, and the outer wall of the limiting mounting plate has a front-to-back through limiting groove. A lifting block is slidably installed in the limiting groove. The lower end of the lifting block is connected to the bottom of the limiting groove through a central spring. The limiting slide includes a bidirectional telescopic slide rod. The lifting block is connected to the rear end face of the fixed section of the bidirectional telescopic slide rod. A support rod is installed at the telescopic end of the bidirectional telescopic slide rod. The front end face of the support rod is connected to the corresponding extrusion strip. A support rod is installed at the front end face of the fixed section of the bidirectional telescopic slide rod. A positioning arc plate is installed at the front end face of the support rod.

[0014] Preferably, the upper surface of the horizontal section of the L-shaped mounting base is provided with an arc groove corresponding to the position of the limiting mounting plate. The lower part of the limiting mounting plate is slidably disposed in the arc groove. The outer wall of the limiting mounting plate is provided with an annular groove. Limiting posts are installed on both the left and right sides of the upper surface of the L-shaped mounting base located in the annular groove. The upper surface of the limiting posts and the inner wall of the arc groove are provided with rotating balls. The multiple balls slide in cooperation with the annular groove.

[0015] Preferably, a positioning cylinder is installed on the lower end face of the compression plate near the front side, and the rear side of the compression plate is slidably disposed in the limiting groove.

The through holes are connected to the arc groove. An insert rod is slidably installed in the through hole and is installed on the front end face of the connecting vertical plate.

[0017] Beneficial effects:

[0018] 1. The clamping mechanism clamps and fixes the air spring damper at multiple positions from bottom to top. The clamping and limiting parts work together to keep the upper part of the air spring damper in sliding clamp position during compression, which greatly improves the stability of the air spring damper. The rotating motor, limiting mounting plate and locking assembly work together to drive the air spring damper to adjust the placement angle and lock it stably. This allows for compression testing of air spring dampers with different angle settings, improving the comprehensiveness of the compression test.

[0019] 2. The lower part of the air spring damper is elastically compressed and limited by the cooperation of the clamping plate and the compression spring. The position of the air spring damper is positioned when it is placed by the set support rod and the positioning arc plate. Then, the bidirectional telescopic rod drives the two clamping blocks to move closer to each other to clamp and fix the outer wall of the larger diameter of the lower part of the air spring damper. At the same time, it also drives the compression strip on the connecting block to move towards the clamping block to clamp and limit the upper part of the air spring damper. Due to the setting of side springs, limiting grooves, lifting blocks and central spring, when the air spring damper is compressed downward, the clamping blocks always limit and clamp the upper part of the air spring damper, and the positioning arc plate always supports and limits the air spring damper. This realizes the limitation and sliding of the air spring damper during compression, which improves stability.

[0020] 3. After a compression test, the rotating motor intermittently rotates a specified angle, causing the limit mounting plate to rotate circumferentially by a specified angle, so that the air spring vibration damper is tilted at a certain angle. At the same time, the compression assembly also rotates by the same angle. Then the compression assembly tests the air spring vibration damper again, realizing the compression test of the air spring vibration damper at different angles. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1 This invention provides a technical solution: an air spring vibration damper performance testing device, comprising an L-shaped mounting base 1, a limiting mounting plate 2, a clamping mechanism 3, and a compression component 4. The limiting mounting plate 2 is provided on the horizontal section of the L-shaped mounting base 1, the clamping mechanism 3 is installed on the front end face of the limiting mounting plate 2, and the compression component 4 is installed on the rear end face of the limiting mounting plate 2. The clamping mechanism 3 includes a base 31, which has an L-shaped structure. The vertical section of the base 31 is installed on the front end face of the limiting mounting plate 2. An adaptive clamping member 32 is installed on the horizontal section of the base 31, and a fixed clamping member 33 is provided on the vertical section of the base 31. A limiting clamping member 34 is provided above the fixed clamping member 33, and the limiting clamping member 34 is connected to the limiting mounting plate 2.

[0029] Please see Figure 3 In this embodiment, the adaptive clamping member 32 includes an inverted L-shaped baffle 321. The inverted L-shaped baffles 321 are symmetrically installed on the upper surface of the horizontal section of the base 31. A pressing plate 322 is provided below the horizontal section of the inverted L-shaped baffle 321. The pressing plate 322 is connected to the inverted L-shaped baffle 321 via multiple compression springs 323 on the side near the vertical section of the inverted L-shaped baffle 321. The upper surface of the pressing plate 322 is slidably connected to the horizontal section of the inverted L-shaped baffle 321, and the lower surface of the pressing plate 322 is slidably connected to the base 31. The front side of the pressing plate 322 is a sloping shape for easy guidance. During operation, by pressing and pushing the lower part of the air spring damper against the front side of the pressing plate 322, the compression springs 323 are compressed, so that the lower part of the air spring damper enters between the two pressing plates 322. The elasticity of the compression springs 323 drives the pressing plates 322 on both sides to compress and limit the lower outer wall of the air spring damper.

[0030] Please see Figure 2 , Figure 3 In this embodiment, the fixing clamping member 33 includes a through block 331. A long groove 332 is formed on the front end face of the vertical section of the base 31. The through block 331 is installed in the middle of the long groove 332. A bidirectional telescopic rod 333 is fixedly installed in the middle of the through block 331. Moving strips 334 are installed at both telescopic ends of the bidirectional telescopic rod 333. A section of the moving strip 334 located within the long groove 332 is slidably connected to the inner wall of the long groove 332. Clamping blocks 335 are installed on opposite sides of the moving strips 334. Multiple anti-slip rubber strips are provided on the clamping end faces of the clamping blocks 335. During operation, the bidirectional telescopic rod 333 is activated, causing the moving strips 334 on both sides to move towards each other within the long groove 332. This causes the two clamping blocks 335 to approach each other, clamping and fixing the outer wall of the lower, larger diameter air spring damper. The anti-slip rubber strips enhance the clamping effect.

[0031] Please see Figure 1 , Figure 2 In this embodiment, the limiting clamping member 34 includes a connecting block 341, which is vertically installed in the middle of the upper end face of the moving strip 334. The connecting block 341 has vertical grooves on opposite sides, and side springs 342 are installed on the lower end face of each vertical groove. Extrusion strips 343 are slidably installed in each vertical groove. The upper end of the side spring 342 is connected to the extrusion strip 343. A clamping block 344 is installed on the opposite side of the extrusion strip 343. The two extrusion strips 343 are connected to the limiting slide member 35. The limiting mounting plate 2 is a disc structure. The outer wall of the limiting mounting plate 2 has a front-to-back through limiting groove 21. A lifting block 22 is slidably installed in the limiting groove 21. The lower end of the lifting block 22 is connected to the bottom of the limiting groove 21 through a central spring 23.

[0032] Please see Figure 2 The limiting slide 35 includes a bidirectional telescopic slide rod 351. The lifting block 22 is connected to the rear end face of the fixed section of the bidirectional telescopic slide rod 351. Each telescopic end of the bidirectional telescopic slide rod 351 is equipped with a support rod 352. The front end face of the support rod 352 is connected to the corresponding extrusion strip 343. The front end face of the fixed section of the bidirectional telescopic slide rod 351 is equipped with a support rod 353. The front end face of the support rod 353 is equipped with a positioning arc plate 354. The support rod 353 and the positioning arc plate 354 can be used to position the air spring damper when it is placed. During operation, the moving strip 334 moves the connecting block 341 synchronously, so that the connecting block 341... The compression bar 343 and clamping block 344 move towards each other to clamp and limit the upper part of the air spring damper. The movement of the compression bar 343 towards each other causes the telescopic shaft of the bidirectional telescopic slide bar 351 to retract. During the compression test, the compression assembly 4 presses down on the upper end of the air spring damper. Due to the presence of side springs 342, limiting grooves 21, lifting blocks 22 and center springs 23, when the air spring damper is compressed downward, the clamping block 344 always clamps and limits the upper part of the air spring damper, and the positioning arc plate 354 always supports and limits the air spring damper, improving stability and realizing the limitation and sliding of the air spring damper while it is being compressed.

[0033] The clamping ends of the abutment plate 322, clamping block 335, and clamping block 344 are all arc-shaped structures, and the size of the abutment plate 322, clamping block 335, and clamping block 344 gradually decreases from bottom to top. Since the size of the air spring damper is a stepped shaft shape with a diameter that gradually decreases from bottom to top, the abutment plate 322, clamping block 335, and clamping block 344 of different sizes can limit and fix multiple positions of the air spring damper, thereby ensuring stability during testing.

[0034] Please see Figure 1 , Figure 5In this embodiment, an arc groove 14 is formed on the upper surface of the horizontal section of the L-shaped mounting base 1, corresponding to the position of the limiting mounting plate 2. The lower part of the limiting mounting plate 2 is slidably disposed in the arc groove 14. An annular groove 24 is formed on the outer wall of the limiting mounting plate 2. Limiting posts 15 are installed on both the left and right sides of the upper surface of the L-shaped mounting base 1 at the annular groove 24. Rollers 16 are rotatably mounted on the upper surface of the limiting posts 15 and the inner wall of the arc groove 14. Multiple rollers 16 slide in cooperation with the annular groove 24. A rotating motor 11 is installed at the front end of the vertical section of the L-shaped mounting base 1. The output shaft of the rotating motor 11 is connected to the limiting post 15. The rear end face of the mounting plate 2 is connected to the center position. The upper end of the horizontal section of the L-shaped mounting base 1 has a mounting cavity 12, and a locking component 13 is provided in the mounting cavity 12. By rotating the motor 11 intermittently by a specified angle, the limiting mounting plate 2 is driven to rotate circumferentially by a specified angle, so that the air spring damper is tilted at a certain angle. At the same time, the compression component 4 also rotates by the same angle. Since the annular groove 24 cooperates with the ball 16 in the arc groove 14 and the ball 16 on the limiting post 15, the stability of the limiting mounting plate 2 during rotation can be guaranteed, and the rotational friction can be reduced.

[0035] Please see Figure 1 , Figure 4 In this embodiment, the compression assembly 4 includes a support plate 41, which is installed on the rear end face of the limiting mounting plate 2. An L-shaped hanging plate 42 is installed on the upper end of the support plate 41. The horizontal section of the L-shaped hanging plate 42 extends above the clamping mechanism 3. A telescopic cylinder 43 is fixedly installed through the horizontal section of the L-shaped hanging plate 42. A compression plate 44 is installed on the telescopic end of the telescopic cylinder 43. A positioning cylinder 441 is installed on the lower end face of the compression plate 44 near the front side. The rear side of the compression plate 44 is slidably disposed in the limiting groove 21. During operation, after the air spring damper is fixed, the telescopic cylinder 43 drives the compression plate 44 to move downward, so that the positioning cylinder 441 is sleeved on the upper end of the air spring damper and presses downward. At the same time, the compression plate 44 compresses the lifting block 22, so that the clamping block 344 and the positioning arc plate 354 move downward synchronously with the air spring damper, ensuring the stability of the compression and improving the accuracy of the test.

[0036] The locking assembly 13 includes an electric telescopic rod 131, which is installed on the rear end face of the mounting cavity 12. A connecting vertical plate 132 is installed on the telescopic end of the electric telescopic rod 131. Limiting through holes 25 are evenly opened along the outer wall of the front end face of the limiting mounting plate 2 near its outer wall. Through holes are opened at corresponding positions on the front end face of the mounting cavity 12 and the limiting through holes 25 located in the arc groove 14. The through holes are connected to the arc groove 14. Insert rods 133 are slidably installed in the through holes and are installed on the front end face of the connecting vertical plate 132. During operation, the electric telescopic rod 131 drives the insert rods 133 on the connecting vertical plate 132 to slide into the corresponding limiting through holes 25 in the through holes, thereby locking and fixing the position of the limiting mounting plate 2.

[0037] In actual operation, the lower part of the air spring damper is pressed against the front side of the clamping plate 322. The support rod 353 and the positioning arc plate 354 are used to position the air spring damper during placement. The compression spring 323 is compressed, causing the lower part of the air spring damper to enter between the two clamping plates 322. The elasticity of the compression spring 323 drives the clamping plates 322 on both sides to compress and limit the lower outer wall of the air spring damper. The bidirectional telescopic rod 333 is activated to drive the moving strips 334 on both sides to move in the long groove. The two clamping blocks 335 move towards each other, bringing them closer together to clamp and fix the outer wall of the lower, larger diameter part of the air spring damper. The moving strip 334 drives the connecting block 341 to move synchronously, causing the pressing strip 343 on the connecting block 341 and the clamping block 344 to also move towards each other, clamping and limiting the upper part of the air spring damper. The moving pressing strip 343 causes the telescopic shaft of the bidirectional telescopic slide rod 351 to retract. During the compression test, the compression assembly 4 presses down on the upper end of the air spring damper. Due to the design... Equipped with a side spring 342, a limiting groove 21, a lifting block 22, and a central spring 23, the clamping block 344 constantly clamps and limits the upper part of the air spring damper when it is compressed downwards, and the positioning arc plate 354 constantly supports and limits the air spring damper, improving stability. This achieves simultaneous compression and limiting sliding. After the air spring damper is fixed, the electric telescopic rod 131 drives the insert rod 133 on the connecting vertical plate 132 to slide into the corresponding limiting through hole 25 through the through hole, thus limiting the installation. The mounting plate 2 is locked in place to ensure compression stability and improve test accuracy. Then, the telescopic cylinder 43 drives the compression plate 44 to move downward, so that the positioning cylinder 441 is fitted onto the upper end of the air spring vibration damper and pressed downward. At the same time, the compression plate 44 compresses the lifting block 22, so that the clamping block 344 and the positioning arc plate 354 move downward synchronously with the air spring vibration damper. By using different telescopic cylinder 43 extension and retraction speeds, static compression and dynamic compression tests can be performed on the air spring vibration damper to observe whether the air spring vibration damper meets the usage requirements.

[0038] Subsequently, the compression component 4 returns to its original position, and then the rotating motor 11 rotates intermittently by a specified angle, driving the limit mounting plate 2 to rotate in a circle by a specified angle, so that the air spring damper is tilted at a certain angle. At the same time, the compression component 4 also rotates by the same angle. The air spring damper is tested again by the compression component 4, realizing the compression test of the air spring damper at different angles.
