[0026] In this embodiment, the first positioning mechanism 2 can provide an effective positioning function, the clamping mechanism 3 facilitates the partial clamping of the spring, thereby improving the stability of the spring during assembly and ensuring safety. The support mechanism 6 is arranged at the bottom to ensure stable support and maintain stable installation between the mechanisms. The appropriate height is selected by adjusting the adjusting screw 702. After the height adjustment is completed, the product is placed on the positioning block 701, and the manual knob is turned to clamp the V-block 502. Under the action of the clamping cylinder 501, the shock absorber body is clamped, which helps the clamping mechanism 5 to provide a stable clamping effect when installing the spring. At the same time, the second positioning mechanism 7 at the bottom further maintains the clamping stability. When the shock absorber is pressed down to the appropriate position, the shock absorber end is placed on the spring, and the positioning plate 203 placed on the positioning push plate 202 extends out along the positioning slide slider 201. After the end position is determined according to the positioning plate 203, the locking nut is tightened to the shock absorber body.

The positioning block 701 cooperates with the adjusting screw 702 to provide bottom support, further ensuring stability. At the same time, it is convenient to provide an effective displacement adjustment function. By manually adjusting the initial position of the downward pressure cylinder 102, the spring is just in the position to be assembled, and the spring is placed on the shock absorber body. The positioning cylinder 101 facilitates the provision of downward force and realizes stable downward pressure work. The downward pressure cylinder 102 cooperates with the slide rail slider 103 to realize the downward pressure action, thereby completing the lifting and lowering adjustment effect. The bottom support frame provides a guiding support, which is conducive to maintaining a stable lifting operation. The hydraulic mechanism 4 facilitates the provision of hydraulic control functions. Example

[0027] like Figure 1-Figure 2 As shown, the clamping mechanism 5 includes a clamping cylinder 501, and a clamping V-block 502 is arranged at one end of the clamping cylinder 501. The clamping mechanism 3 includes a first clamping plate 301, and a clamping U-shaped plate 302 is arranged on the inner side of the first clamping plate 301. A second clamping plate 303 is arranged at one end of the first clamping plate 301, and an adjusting plate 304 is symmetrically arranged on the side of the clamping U-shaped plate 302, and the adjusting plate 304 is arranged on the inner side of the first clamping plate 301.

[0028] The U-shaped clamping plate 304 is adjusted to a desired position according to the rotation direction of the spring, and the U-shaped clamping plate 302 is used to hold the spring tightly in place according to the rotation direction of the spring. The U-shaped clamping plate 302 has a groove with the same rotation direction as the spring, and limits the spring in both the axial and radial directions, which helps the first clamping plate 301 to provide a side-mounted clamping support. The U-shaped clamping plate 302 facilitates the clamping effect of the spring, and then the second clamping plate 303 is securely buckled and locked. The manual button is pressed, and the downward pressure cylinder 102 slowly presses down the entire clamping mechanism, so that the second clamping plate 303 can further provide a clamping function, thereby effectively improving the stability of the spring during installation. The adjustment plate 304 provides a displacement adjustment function, which further improves the range of operation.

[0029] The working principle of this embodiment is as follows: when using, when changing the product for the first time, first select the appropriate height by adjusting the adjusting screw 702. After the height adjustment is completed, place the product on the positioning block 701, turn the manual knob, clamp the V-block 502, and under the action of the clamping cylinder 501, clamp the shock absorber body, manually adjust the initial position of the pressing cylinder 102 so that the spring is just in the position to be assembled, place the spring on the shock absorber body, and adjust the adjusting plate 304 to the appropriate position according to the rotation direction of the spring. At this time, the clamping U-plate 302 holds the spring tightly according to the rotation direction of the spring. This clamping U-plate 302 has a spring inside. The card slots with the same rotation direction limit the springs in both axial and radial directions, and then the second clamping plate 303 is safely locked by the buckle. The manual button is pressed, and the downward pressure cylinder 102 slowly presses down the entire clamping mechanism. When it is pressed down to the appropriate position, the shock absorber end is placed on the spring, and the positioning plate 203 placed on the positioning push plate 202 is extended along the positioning slide rail slider 201. After the end position is determined according to the positioning plate 203, the locking nut and the shock absorber body are tightened. At this time, the downward pressure cylinder 102 rises, and the clamping cylinder 501 is retracted. The shock absorber assembly after press-fitting is removed, a cycle is ended, and the assembly work is completed.
