Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0023] See also Figures 1-4 The present embodiment provides a shock-absorbing spring testing device, including a base 1, a lower clamp 2 is fixedly connected to the top of the base 1, an upper clamp 3 is provided above the lower clamp 2, a twisting assembly 5 is provided on the upper clamp 3, and the twisting assembly 5 includes a top plate 51, a motor 52 is fixedly connected to the bottom of the top plate 51, and the top plate 51 provides support for the use of the motor 52. The output end of the motor 52 is fixedly connected to a rotating plate 53, and the rotating plate 53 is elliptical. The outer side of the rotating plate 53 is hinged with a swinging plate 54, and the middle rear end of the swinging plate 54 is hinged with a first sliding plate. The movable block 55 includes a first sliding block 55, the rear end of which is slidably connected to a fixed frame 56. The fixed frame 56 is in a concave shape, and a support block 57 is fixedly connected to the top of the fixed frame 56. The support block 57 is a rectangular parallelepiped. A second sliding block 58 is hingedly connected to the bottom left of the swing plate 54. The second sliding block 58 is in an H shape. A circular plate 59 is provided on the outside of the second sliding block 58. The circular plate 59 has a sliding groove 510. The sliding groove 510 is in a rectangular parallelepiped. A support column 511 is hingedly connected to the middle top of the circular plate 59. The top of the upper clamp 3 is fixedly connected to the bottom of the circular plate 59. The second sliding block 58 is slidably connected in the sliding groove 510. The top of the support column 511 is fixedly connected to the bottom of the top plate 51. The top of the support block 57 is fixedly connected to the bottom of the top plate 51. The top plate 51 is set at the top left of the base 1.

[0024] When the above-mentioned device is used, after the spring to be tested is fixed by the upper clamp 3 and the lower clamp 2, the movement of the motor 52 drives the rotating plate 53 to rotate, and the rotation of the rotating plate 53 drives the first sliding block 55 on the swing plate 54 to slide left and right in the fixed frame 56, so that the swing plate 54 can achieve stable shaking, and the movement of the swing plate 54 drives the second sliding block 58 to slide back and forth in the slide groove 510, so that the circular plate 59 outside the slide groove 510 can rotate on the support column 511. Example

[0025] See also Figures 1-4 On the basis of Example 1, a push column 4 is fixedly connected to the bottom right side of the top plate 51, and the push column 4 provides support for the use of the top plate 51. An adjustment component 6 is provided at the bottom of the push column 4. The adjustment component 6 includes a hydraulic cylinder 61, and the output end of the hydraulic cylinder 61 is fixedly connected to a push frame 62. The push frame 62 is triangular, and the bottom outer wall of the push frame 62 is slidably connected to a limit frame 63. The limit frame 63 is in a "concave" shape. The top of the push frame 62 is slidably connected to a roller 64, and the upper outer wall of the roller 64 is hinged to a connecting frame 65. The connecting frame 65 is in a "U" shape. The top of the connecting frame 65 is fixedly connected to the bottom of the push column 4, and the outer wall of the push column 4 is slidably connected to a limit ring 67. The limit ring 67 is in a hollow cylindrical shape, and the outer wall of the limit ring 67 is fixedly connected to the upper middle part of the support frame 66. The support frame 66 is "L"-shaped, the bottom of the hydraulic cylinder 61 is fixedly connected to the top of the base 1, the bottom of the limiting frame 63 is fixedly connected to the top of the base 1, and the rear end bottom of the support frame 66 is fixedly connected to the top of the base 1.

[0026] When the above-mentioned equipment is used, after the twisting component 5 has completed the inspection of the spring, the hydraulic cylinder 61 drives the pushing frame 62 to move to the right on the limit frame 63, so that the pushing frame 62 can move stably to the right. The rightward movement of the pushing frame 62 drives the roller 64 to slide on the pushing frame 62, so that the pushing column 4 on the connecting frame 65 outside the roller 64 moves upward in the limit ring 67. The upward movement of the pushing column 4 drives the top plate 51 to move upward, and the opposite movement can realize the downward movement of the pushing column 4.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
