[0027] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 3 As shown, a novel vibration isolation testing device for automotive shock absorbers includes a base 11, on which a base platform 12 is fixedly connected. Two symmetrical mounting plates 29 are fixedly mounted on the base 11 on the front side of the base platform 12. A positive and negative threaded rod 28 is rotatably connected between the two mounting plates 29. A second servo motor 32 for driving the positive and negative threaded rod 28 to rotate is mounted on one of the mounting plates 29.

[0030] Two movable plates 26 are symmetrically connected to the positive and negative toothed rods 28, arc-shaped grooves 27 are formed in the opposite sides of the two movable plates 26, a mounting cavity 30 is formed in the base 12, a plurality of pressure sensors 13 are mounted in the mounting cavity 30, and an iron plate 33 is slidably mounted in the mounting cavity 30 and connected to the elastic components of the pressure sensors 13.

[0031] It should be noted that the pressure sensors 13 in the embodiment are supported by a large number of mature technologies, and the essence of the utility model lies in optimizing and combining the existing hardware machine connection mode for specific application occasions to adapt to the problem of how to test the shock isolation performance of the sample (without changing the internal structure of the pressure sensors 13).

[0032] Before starting the test, the two movable plates 26 are first moved towards each other by a certain distance, then the technician places the sample to be tested on the base 12, and then the two movable plates 26 move towards each other under the drive of the positive and negative toothed rods 28, so that the arc-shaped grooves 27 on the two movable plates 26 approach each other, until the sample to be tested is sleeved in the two arc-shaped grooves 27 (the inner wall of the arc-shaped groove 27 abuts against the sample to be tested, but does not tightly abut against the sample to be tested, so as to avoid the friction between the inner wall of the arc-shaped groove 27 and the sample to be tested causing test result error), so as to achieve the purpose of ensuring the verticality of the sample to be tested.

[0033] The base 11 is fixedly provided with a stand 14, a sliding groove 15 is formed in the stand 14, a striking plate 16 is slidably connected in the sliding groove 15, a slide rod 22 is fixedly connected in the sliding groove 15, and the striking plate 16 comprises a sliding seat 21 which is slidably connected to the slide rod 22, so that the striking plate 16 is prevented from falling out of the sliding groove 15 during upward and downward sliding.

[0034] A roller 17 is rotatably connected to the upper end surface of the stand 14, a first servo motor 18 is mounted on the stand 14 for driving the roller 17 to rotate, a steel cable 19 is wound on the outer curved surface of the roller 17, and the end of the steel cable 19 is fixedly connected to the striking plate 16.

[0035] After the technician fixes the sample to be tested and adjusts the falling height of the striking plate 16, the technician drives the roller 17 to quickly release the steel cable 19 through the first servo motor 18, so as to realize the rapid falling of the striking plate 16 and the striking on the upper end of the sample to be tested, at this time, the iron plate 33 slides downward under the impact force, so that the pressure sensor 13 senses the impact force and outputs data.

[0036] It should be noted that before starting the test, the technician needs to use the same volume of the sample to be tested, the same height of the article to carry out the control group experiment, so that the technician compares the data in the subsequent test process, so as to judge the shock isolation performance of the sample to be tested.

[0037] After the test is completed, the roller 17 is driven to rotate by the servo motor 18, so that the steel cable 19 is wound, and the impact plate 16 is driven to move upwards and not in contact with the sample to be tested, and then the two movable plates 26 move towards each other and no longer clamp the sample to be tested, so that the technician takes down the sample to be tested.

[0038] If the technician wants to change the falling height of the impact plate 16, first make the servo motor 18 drive the roller 17 to rotate, and then make the steel cable 19 drive the impact plate 16 to descend, when the impact plate 16 descends to the required height, the roller 17 stops rotating, so that the impact plate 16 can stop in the air, so as to get the required falling height for testing, and the front side of the stand 14 is provided with a scale 31, and the technician can accurately adjust the falling height of the impact plate 16 according to the scale 31, so as to avoid errors in the test results.

[0039] In addition, the upper end surface of the impact plate 16 is fixedly connected with a plug column 24, and different specifications of weights 25 can be placed on the plug column 24, so that the technician can test how the sample to be tested isolates the impact of different degrees under the same falling height.

[0040] At the same time, it should be pointed out that the terms such as "front", "rear", "vertical", "horizontal" and the like indicated by the directions or positional relationships shown in the drawings are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the protection scope of the utility model.

[0041] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
