[0030] Further, such as Figure 5 As shown, the clamping assembly includes two second guide rods 9 fixedly connected to the top of the lower clamp plate 6, and the upper clamp plate 7 slides on the two second guide rods 9; the other end of the upper clamp plate 7 is threadedly connected to a threaded rod 8, and the bottom of the threaded rod 8 is rotatably connected to the top of the lower clamp plate 6 through a bearing, and the top of the threaded rod 8 is fixedly connected to a rotary block 26.

[0031] During operation, when the automobile suspension needs to be fixed, the rotary block 26 is rotated, and the rotary block 26 drives the threaded rod 8 to rotate, and the threaded rod 8 drives the upper clamping plate 7 to move. During the movement of the upper clamping plate 7, the upper clamping plate 7 slides on the second guide rod 9, and the second guide rod 9 limits the upper clamping plate 7 in the vertical direction until the upper clamping plate 7 fixes the automobile suspension between the upper clamping plate 7 and the lower clamping plate 6 and stops moving.

[0032] Further, such as Figure 5 As shown, a driven wheel 10 is fixedly connected to the outer side wall of one end of the bidirectional ball screw 3; a first motor 13 is fixedly connected to one side wall of the detection box 2 through a connecting plate, and an output shaft of the first motor 13 is fixedly connected to one side wall of the driving wheel 11, and the other side wall of the driving wheel 11 is rotatably connected to the inner wall of the detection box 2 through a pin shaft, and one end of a belt 12 is sleeved on the outer side of the driving wheel 11, and the other end of the belt 12 is sleeved on the outer side of the driven wheel 10.

[0033] During operation, when the bidirectional ball screw 3 needs to be driven, the first motor 13 is turned on, and the first motor 13 drives the driving wheel 11 to rotate through the output shaft. During the rotation of the driving wheel 11, the driving wheel 11 drives the belt 12 to rotate, and the belt 12 drives the driven wheel 10 to rotate, and the driven wheel 10 drives the bidirectional ball screw 3 to rotate, thereby realizing the rotation of the bidirectional ball screw 3.

The second motor 21 drives the disc 20 to rotate through the output shaft, and the disc 20 drives the triangular block 22 to rotate. During the rotation of the triangular block 22, the universal wheel 24 is lifted upward. When the universal wheel 24 moves to a higher position of the triangular block 22, it can fall down to complete a lifting movement. The universal wheel 24 drives the lifting column 23 to move up and down through the mounting frame. The lifting column 23 drives the top plate 17 to move up and down. The top plate 17 lifts and lowers the detection box 2 to simulate various road conditions and test the automobile suspension.

[0036] Further, such as Figure 5 As shown, through holes are formed between the upper clamping plate 7 and the lower clamping plate 6, and the two through holes are used to place the automobile suspension.

[0041] During operation, when the top plate 17 is in the process of lifting and lowering, the top plate 17 pushes the detection box 2 , and the detection box 2 slides on the slide column 15 through the side plate 14 , and under the action of the first spring 16 , the movement and reset of the detection box 2 are facilitated.

[0042] Further, such as Figure 2 As shown, the top plate 17 is disposed directly below the detection box 2, and the top plate 17 is used to push the detection box 2 to perform lifting movements.

[0043] During operation, the top plate 17 is disposed directly below the detection box 2 , so that the top plate 17 can push the detection box 2 to achieve the lifting movement of the detection box 2 .

[0044] Working principle: when the automobile suspension needs to be tested, the first motor 13 is turned on, and the first motor 13 drives the driving wheel 11 to rotate through the output shaft. During the rotation of the driving wheel 11, the driving wheel 11 drives the belt 12 to rotate, and the belt 12 drives the driven wheel 10 to rotate, and the driven wheel 10 drives the bidirectional ball screw 3 to rotate, and the bidirectional ball screw 3 drives the movable plate 5 to move in the opposite direction. Since a ball nut seat is provided at the connection between the bidirectional ball screw 3 and the movable plate 5, the radial movement of the movable plate 5 is guaranteed by the ball nut seat, wherein the movable plate 5 slides on the first guide rod 4 during the movement, and the first guide rod 4 limits the movable plate 5 in the horizontal direction; the movable plate 5 drives the lower clamping plate 6 to move during the movement, and stops moving when the length between the lower clamping plates 6 matches the size of the automobile suspension, and the rotary block 26 is rotated, and the rotary block 26 drives the threaded rod 8 to rotate, and the threaded rod 8 is rotated. The rod 8 drives the upper clamping plate 7 to move. During the movement of the upper clamping plate 7, the upper clamping plate 7 slides on the second guide rod 9. The second guide rod 9 limits the upper clamping plate 7 in the vertical direction until the upper clamping plate 7 fixes the automobile suspension between the upper clamping plate 7 and the lower clamping plate 6 and stops moving, thereby realizing fixed detection of suspensions of different sizes. When the automobile suspension is being detected, the second motor 21 needs to be turned on. The second motor 21 drives the disc 20 to rotate through the output shaft, and the disc 20 drives the triangular block 22 to rotate. During the rotation of the triangular block 22, the universal wheel 24 is lifted upward. When the universal wheel 24 moves to a higher position of the triangular block 22, it can fall down and complete a lifting movement. The universal wheel 24 drives the lifting column 23 to lift and lower through the mounting frame. The lifting column 23 drives the top plate 17 to lift and lower. The top plate 17 lifts and lowers the detection box 2, thereby simulating various road conditions on the road surface and detecting the automobile suspension.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
