Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, a hydraulic vibration damper testing device includes a testing platform body 1; a fixing plate 11 is fixedly connected to the middle of the testing platform body 1; a sliding groove 12 is formed in the middle of the fixing plate 11; a pressure plate 13 is slidably connected to the middle of the sliding groove 12; a first hinge 14 is rotatably connected to the middle of the fixing plate 11; a retaining plate 15 is fixedly connected to the middle of the first hinge 14; a placement cavity 16 is formed in the middle of the fixing plate 11; multiple sets of spring rods 17 are fixedly connected to the middle of the pressure plate 13; a compression plate 18 is fixedly connected to the end of the spring rod 17; a retaining bolt 19 is slidably connected to the middle of the retaining plate 15; when it is necessary to test the vibration damper, it can be placed in the cavity 16 formed in the middle of the fixing plate 11. The damper is placed inside the placement cavity 16, and then the pressure plate 13 can be inserted into the slide groove 12. At this time, the compression plate 18 can be used to contact the damper. Through the action of the spring rod 17, the compression plate 18 can be used to fix it. Then, the retaining plate 15 can be rotated through the first hinge 14, and then the retaining bolt 19 is used to fix the retaining plate 15 and the fixing plate 11. Thus, the damper placed inside the placement cavity 16 can be fixed. This step can fix the damper to be tested in the middle of the fixing plate 11 when the damper needs to be tested, thereby reducing the occurrence of the damper falling off during the test and reducing the occurrence of damage to the damper during the test.

[0025] like Figures 2-4As shown, the detection platform body 1 middle part is fixed with motor cavity 2; The detection platform body 1 middle part is fixed with motor 21; The output end of the motor 21 is fixed with screw rod 22; The screw rod 22 middle part is engaged with nut 23; The nut 23 middle part is rotatably connected with connecting ring 24; The connecting ring 24 middle part is fixed with push plate 25; The detection platform body 1 middle part is provided with positioning groove 26; The push plate 25 and positioning groove 26 are slidably connected; When detecting the shock absorber, the motor 21 in the middle part of the motor cavity 2 can work, and then the nut 23 can rotate in the middle part of the screw rod 22, and then the connecting ring 24 can push the push plate 25 to slide in the middle part of the positioning groove 26, and then the shock absorber can be extruded, which can reduce the damage of the shock absorber during detection.

[0026] As shown in the figure, Figure 1 The detection platform body 1 middle part is rotatably connected with a plurality of second hinges 3; The second hinge 3 middle part is fixed with protective cover plate 31; The protective cover plate 31 and detection platform body 1 are slidably connected; When detecting the shock absorber, the protective cover plate 31 can be rotated by the second hinge 3, and then the protective cover plate 31 can be placed at the end of the detection platform body 1, and then the shock absorber can be closed during detection, which can reduce the situation that foreign matter splashes and causes injury during detection, and then the workers can be protected during detection.

[0027] As shown in the figure, Figure 2 The detection platform body 1 middle part is provided with buffer groove 4; A plurality of damping rods 41 are fixed in the middle part of the buffer groove 4; The end of the damping rod 41 is fixed with rubber sheet 42; When the protective cover plate 31 is placed at the end of the detection platform body 1, the protective cover plate 31 can first contact the rubber sheet 42, and then the impact force of the protective cover plate 31 on the rubber sheet 42 can be weakened by the buffering action of the damping rod 41, which can reduce the situation that the protective cover plate 31 excessively impacts the end of the detection platform body 1, causing damage to the detection platform body 1, and then the detection platform body 1 can be protected.

[0028] As shown in the figure, Figures 1-2 The detection platform body 1 middle part is fixed with electric push rod 5; The end of the electric push rod 5 is fixed with branch 51; When detecting the shock absorber, it can be placed in the middle part of the branch 51, and then the electric push rod 5 can work to support the shock absorber, which can reduce the damage of the shock absorber during detection.

[0029] As shown in Figures 1-2 The detection platform body 1 is provided with an observation window 6 in the middle; during the detection of the shock absorber, the detection process can be observed through the observation window 6, which can improve the detection efficiency of the shock absorber and reduce the occurrence of insufficient data observation during the detection process.

[0030] As shown in Figures 2-3 The end of the extrusion piece 18 is fixedly connected with a baffle 7; during the fixation of the shock absorber by the extrusion piece 18, the side surface can be extruded by the baffle 7, which can reduce the shaking of the shock absorber during the fixation.

[0031] The working principle is that when the shock absorber needs to be detected, it can be placed in the placement cavity 16 in the middle of the fixed plate 11, and then the pressing plate 13 can be inserted into the sliding groove 12. At this time, the pressing piece 18 can be used to contact the shock absorber. Through the action of the spring rod 17, the pressing piece 18 can be used to fix it. Then the retaining piece 15 can be rotated by the first hinge 14, and then the retaining piece 15 and the fixed plate 11 can be fixed by the retaining bolt 19. Thus, the shock absorber placed in the placement cavity 16 can be fixed. This step can fix the shock absorber to be detected in the middle of the fixed plate 11, thereby reducing the situation that the shock absorber falls during detection, and reducing the situation that the shock absorber is damaged during detection. When the shock absorber is detected, the motor 21 in the middle of the motor cavity 2 can work, thereby making the nut 23 rotate in the middle of the screw rod 22, thereby making the connecting ring 24 push the push plate 25 to slide in the middle of the positioning groove 26, and thereby the shock absorber can be squeezed and detected. This step can detect the shock absorber by slowly rotating the screw rod 22, thereby reducing the situation that the shock absorber is damaged during detection. When the shock absorber is detected, the protective cover plate 31 can be placed at the end of the detection table body 1 by rotating the second hinge 3, thereby closing the shock absorber during detection. This step can reduce the situation that foreign matter splashes and causes injury during detection when the shock absorber is detected, thereby protecting the workers during detection. When the protective cover plate 31 is placed at the end of the detection table body 1, the protective cover plate 31 can first contact the rubber piece 42, and then the impact force of the protective cover plate 31 on the rubber piece 42 can be reduced by the buffering action of the damping rod 41. This step can reduce the situation that the protective cover plate 31 excessively impacts the end of the detection table body 1, thereby damaging the detection table body 1, thereby protecting the detection table body 1. When the shock absorber is detected, it can be placed in the middle of the support piece 51, and then the electric push rod 5 can work to support the shock absorber. This step can reduce the situation that the shock absorber is damaged during detection by supporting the shock absorber during detection. When the shock absorber is detected, the detection process can be observed through the observation window 6. This step can improve the detection efficiency of the shock absorber and reduce the situation that the data observation is insufficient during detection. When the shock absorber is fixed by the pressing piece 18, the side of the shock absorber can be pressed by the blocking piece 7. This step can reduce the situation that the shock absorber shakes when it is fixed.
