Description

Technical Field

[0001] This utility model relates to the technical field of shock absorber testing equipment, specifically to a shock absorber durability testing equipment. Background Technology

[0002] Shock absorbers are devices used to reduce the amplitude of vibration of a target object. They are also one of the commonly used components in many mechanical equipment, especially some machines that actively or passively generate bumps and vibrations. Shock absorbers mainly consume vibration impact force by extension and contraction, and most of them are made of practical springs.

[0003] Shock absorbers also have a limited lifespan. When they reach their lifespan, their damping effect will decrease or even be lost. Therefore, after the shock absorbers are manufactured, their lifespan needs to be tested to avoid the shock absorbers suddenly reaching their lifespan and affecting the operation of the corresponding machinery.

[0004] Current testing equipment primarily involves vertical vibration of the shock absorber, causing it to operate at high frequency. The lifespan is then determined based on this operating condition. However, in reality, vibrations are not limited to vertical vibrations, leading to incomplete testing and affecting the final lifespan data. Therefore, this paper proposes a shock absorber durability testing device. Utility Model Content

[0005] The technical problem this invention aims to solve is that current testing equipment primarily uses vertical vibration to shock absorbers, causing them to operate at high frequencies and determining their lifespan based on the operating conditions. However, in reality, vibrations occur in more than just vertical motion, leading to incomplete testing. This invention provides a shock absorber durability testing device that simulates vibration forces acting on the shock absorber from different directions, thereby improving the comprehensiveness of the testing and ensuring the accuracy of the data.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a shock absorber durability testing device, including a processing table, two sliding grooves are opened on the top side wall of the processing table near the middle position, a rear upright plate is fixedly connected to the top of the processing table near one side edge, a pressing plate is provided between the rear upright plate and the processing table, a groove is opened in the middle of the side wall opposite to the processing table of the pressing plate, and a bonding piece is movably embedded in the groove, the bonding piece contacts and adheres to the shock absorber through its bottom side wall.

[0007] As a preferred technical solution of this utility model, the middle sidewall of the groove is detachably connected to a docking post, and the bottom end of the docking post is rotatably connected to a ball bearing. The ball bearing has a spherical structure and is fixedly connected to the middle of the top sidewall of the bonding piece.

[0008] As a preferred technical solution of this utility model, the pressing plate is provided with a moving groove at a position away from the processing table and close to the middle of both ends. A follower block is slidably connected in the moving groove. Lower connecting plates are fixedly connected to the two sides of the top of the follower block. A telescopic rod is rotatably connected between the lower connecting plates.

[0009] As a preferred technical solution of this utility model, the two side walls of the follower block that are far apart from each other are fixedly connected with side blocks, and the two opposite side walls of the moving groove are provided with limit grooves, and the side blocks are slidably connected in the limit grooves.

[0010] As a preferred technical solution of this utility model, the telescopic rod is rotatably connected to the upper connecting plate on both sides of the end away from the follower block, and the upper connecting plate is fixedly connected to the bottom side wall of the horizontal plate of the rear upright plate through one end.

[0011] As a preferred technical solution of this utility model, the processing table has an installation groove on the side wall between the two slides. A double-headed motor is detachably connected in the installation groove. Both ends of the double-headed motor are detachably connected to studs, and the threads on the two studs are opposite. A slider is threaded onto the stud. A strong magnetic block is fixedly connected to the top side wall of the installation groove. An isolation plate is fixedly connected to the side wall of the installation groove between the strong magnetic block and the double-headed motor.

[0012] As a preferred embodiment of this utility model, a retaining strip is fixedly connected to the top of the stud. The retaining strip has an L-shaped structure, and a pressure pad is fixedly connected to the bottom side wall of the horizontal plate of the retaining strip. One end of the pressure pad has an inclined structure.

[0013] This utility model has the following advantages: because there is a bonding piece connected to the bottom of the pressing plate, and the bonding piece can rotate completely through the ball bearings, the orientation angle of the pressing plate can be adjusted as needed when the pressing plate drives the shock absorber, thereby simulating the effect of vibration at different angles on the shock absorber. This range is not large and is within the range that can stimulate the shock absorber to move and absorb vibration, thereby improving the comprehensiveness of the test and ensuring the reliability of the test life data.

[0014] The telescopic rods can drive the pressing plate to move. The two telescopic rods, connected by the upper and lower connecting plates, can adjust the orientation angle of the telescopic rods, thereby cooperating with the bonding plate to detect vibrations of the shock absorber in different directions and angles.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to the following: Figure 1-3 This utility model discloses a shock absorber durability testing device, including a processing table 1. Two sliding grooves 2 are opened on the top side wall of the processing table 1 near the middle position. A rear upright plate 7 is fixedly connected to the top of the processing table 1 near one side edge. A pressing plate 8 is provided between the rear upright plate 7 and the processing table 1. A groove 16 is opened in the middle of the side wall opposite to the processing table 1 of the pressing plate 8. A bonding piece 19 is movably embedded in the groove 16. The bonding piece 19 contacts and adheres to the shock absorber through its bottom side wall. A docking post 17 is detachably connected to the middle side wall of the groove 16. A ball bearing 18 is rotatably connected to the bottom end of the docking post 17. The ball bearing 18 has a spherical structure and is fixedly connected to the middle of the top side wall of the bonding piece 19.

[0021] The technical effect of this solution is as follows: the pressing plate 8 is lowered while ensuring that the bonding piece 19 is bonded to one end of the shock absorber. Then, the telescopic rod 10 reciprocates at high speed, thereby driving the pressing plate 8 to press and extend the shock absorber, thus driving the shock absorber to continuously extend and retract. This allows for the testing of the shock absorber's service life. Because the bonding piece 19 can rotate in all directions, it ensures that the bonding piece 19 remains stably bonded to the shock absorber even when the pressing plate 8 is tilted, ensuring that the shock absorber can be tested at different angles.

[0022] The pressing plate 8 has a moving groove 9 at a position away from the processing table 1 and close to the middle of both ends. A follower block 11 is slidably connected in the moving groove 9. Lower connecting plates 14 are fixedly connected to the two sides of the top of the follower block 11. A telescopic rod 10 is rotatably connected between the lower connecting plates 14. Side blocks 12 are fixedly connected to the two side walls of the follower block 11 that are far apart from each other. Limiting grooves 13 are opened on the two opposite side walls of the moving groove 9. The side blocks 12 are slidably connected in the limiting grooves 13. An upper connecting plate 15 is rotatably connected to the two sides of the end of the telescopic rod 10 away from the follower block 11. The upper connecting plate 15 is fixedly connected to the bottom side wall of the horizontal plate of the rear upright plate 7 through one end.

[0023] The technical effect of this solution is that the lower connecting plate 14 and the upper connecting plate 15 ensure that the telescopic rod 10 runs smoothly when the driving pressing plate 8 tilts and rotates. At the same time, the moving groove 9 and the follower block 11 can slide accordingly according to the adjustment. The lower connecting plate 14 and the upper connecting plate 15 work together to avoid motion interference that would affect the driving of the shock absorber.

[0024] The processing table 1 has a mounting groove 20 on its side wall between two slides 2. A double-headed motor 21 is detachably connected in the mounting groove 20. Both ends of the double-headed motor 21 are detachably connected to studs 3, and the threads on the two studs 3 are opposite. A slider 4 is threaded onto the stud 3. A strong magnetic block 22 is fixedly connected to the top side wall of the mounting groove 20. An isolation plate 23 is fixedly connected to the side wall of the mounting groove 20 between the strong magnetic block 22 and the double-headed motor 21. A retaining strip 5 is fixedly connected to the top of the stud 3. The retaining strip 5 has an L-shaped structure. A pressure pad 6 is fixedly connected to the bottom side wall of the horizontal plate of the retaining strip 5. One end of the pressure pad 6 has an inclined structure.

[0025] The technical effect of this solution is as follows: the two clamping strips 5 are moved to the designated position, and then the edge of the shock absorber base is inserted under the pressure pad 6 to press and position the shock absorber. With the adsorption of the strong magnetic block 22, the shock absorber will not tilt or fall over during the testing process, ensuring that the testing is carried out smoothly. Similarly, the horizontal plate on the clamping strip 5 can clamp and position the shock absorber, realizing the positioning of different shock absorbers.

[0026] Specifically, when using this utility model, first start the dual-head motor 21 to drive the stud 3 to rotate, then move the two locking strips 5 to the designated position through the threaded connection, then insert the side of the shock absorber base under the pressure pad 6, and after the shock absorber is fixed, start the telescopic rod 10 to lower the pressure plate 8. The lowered pressure plate 8 presses down on the shock absorber, and then rises rapidly. Due to the characteristics of the shock absorber itself, it moves back and forth quickly. Repeat this step to test the service life of the shock absorber. At the same time, as needed, adjust the tilt angle of the pressure plate 8 by cooperating with the two telescopic rods 10. The set fitting piece 19 can ensure that the adjustment still effectively presses down on the shock absorber. Then repeat the above steps to test the vibration of the shock absorber at different orientation angles.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0028] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
