[0004] However, in actual use, the inventor discovered that when assembling existing shock absorbers, many components are in an active state during pre-assembly, and the shock absorption effect fluctuates due to errors in the assembly position of the components during the pressing process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting a special structural design for the press-fit assembly. Before tightening the nut, the spring of the shock absorber is pressed down and limited, thereby fixing the moving parts.

[0009] Preferably, the transmission component includes a servo unit, a transmission wheel a disposed at the output end of the servo unit, two sets of transmission wheels b rotatably disposed on the mounting plate and driving the corresponding lead screws synchronously, and a transmission belt driving the transmission wheels a and b synchronously.

[0010] Preferably, the positioning component includes a guide mounted on the lifting plate and a positioning component that is vertically slidable along the guide and has a positioning groove opened on the lifting plate.

[0011] Preferably, the guide includes a fixed plate, two sets of guide rails a symmetrically arranged on the fixed plate, two sets of guide seats a correspondingly slidably arranged on the guide rails a, and a connecting plate a connected to the two sets of guide seats a. The guide seats a are driven vertically by a pneumatic unit a.

[0012] Preferably, the positioning component includes a connecting frame with a U-shaped structure connected to the lower end of the connecting plate a, a pressure plate that is horizontally slidably disposed on the connecting frame, a pressure head that is installed on the lower end of the pressure plate and matched with the upper end structure of the end cap, and a handle disposed on one side of the pressure plate. The connecting plate a and the pressure plate are coaxially provided with positioning holes along the vertical direction, and bolts pass through the positioning holes to fix the connecting plate a and the pressure plate.

The third sliding component quickly compresses the spring through the end cover to facilitate the pre-installation of the nut. Energy dissipation and structural protection are achieved through graded buffering and step-by-step displacement, which improves its safety and enhances its adaptability.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Example 1 like Figure 1 As shown, a shock absorber upper support component press-fitting device includes a tooling 2 mounted on a workbench 1, and a press-fitting component 3 mounted on the workbench 1. The pressing assembly 3 includes a sliding assembly 31 located directly above the tooling 2, a transmission assembly 32 that drives the sliding assembly 31 to move up and down, a positioning assembly 33 installed in the middle of the sliding assembly 31 and sliding vertically on the sliding assembly 31, and a clamping assembly 34 installed below the sliding assembly 31.

[0027] Furthermore, such as Figure 3-4 As shown, the sliding assembly 31 includes a lifting plate 311, four sets of sliding cylinders 312 respectively installed at the four corners of the lifting plate 311, and two sets of support columns a313 respectively installed at both ends of the sliding cylinders 312 along the length direction.

[0028] Furthermore, the transmission assembly 32 includes a mounting plate 321, a transmission component 322 mounted on the mounting plate 321, a sliding column 323 with one end connected to the lower end of the mounting plate 321 and the other end connected to the upper part of the workbench 1, and two sets of lead screws 324 correspondingly mounted in the support column a313. The sliding column 323 is provided in four groups, and each group of sliding cylinders 312 slides in the corresponding sliding column 323.

[0029] Among them, such as Figure 2 As shown, the transmission component 322 includes a servo unit 3221, a transmission wheel a3222 disposed at the output end of the servo unit 3221, and two sets of transmission wheels b3223 rotatably disposed on the mounting plate 321 and driving the corresponding lead screw 324 synchronously. The transmission belt 3224 drives the transmission wheels a3222 and b3223 synchronously.

[0030] In detail, the servo unit 3221 starts and drives the transmission wheel a3222 to rotate. The transmission wheel a3222 drives the transmission wheel a3222 and the transmission wheel b3223 to rotate synchronously through the transmission belt 3224. The lead screw 324 drives the lifting plate 311 to move up and down.

[0031] Furthermore, such as Figure 3-4 As shown, the positioning component 33 includes a guide 331 mounted on the lifting plate 311 and a positioning component 332 that is vertically slidably disposed along the guide 331 in a positioning groove 330 opened on the lifting plate 311. The guide component 331 includes a fixed plate 3311, two sets of guide rails a3312 symmetrically arranged on the fixed plate 3311, two sets of guide seats a3313 correspondingly slidably arranged on the guide rails a3312, and a connecting plate a3314 connected to the two sets of guide seats a3313. The guide seats a3313 are driven vertically by a pneumatic unit a3315.

[0032] Furthermore, the positioning component 332 includes a connecting frame 3321 with a U-shaped structure connected to the lower end of the connecting plate a3314, a pressure plate 3322 horizontally slidably disposed on the connecting frame 3321, a pressure head 3323 installed on the lower end of the pressure plate 3322 and matched with the upper end structure of the end cap, and a handle 3324 disposed on one side of the pressure plate 3322; The connecting plate a3314 and the pressure plate 3322 are coaxially provided with a positioning hole 3325 in the vertical direction, and the positioning bolt 3326 passes through the positioning hole 3325 to fix the connecting plate a3314 and the pressure plate 3322.

[0033] The openings 3320 of the pressure head 3323, pressure plate 3322, and connecting plate a3314 are sequentially extended upwards and coaxially arranged.

[0034] In this embodiment, by setting the guide 331 in conjunction with the sliding component 31, the pressure head 3323 is lowered in three stages. In the first stage, the sliding component 31 quickly moves down to the top of the end cap, and then the guide 331 moves to make the pressure head 3323 fully act on the upper surface of the end cap and contact it. In the third stage, the sliding component 31 quickly compresses the spring through the end cap to facilitate the pre-installation of the nut. Through graded buffering and step-by-step displacement, energy dissipation and structural protection are achieved, which improves safety and enhances adaptability.

[0035] The pressure plate 3322 is detachably mounted on the connecting frame 3321, enabling quick replacement of pressure heads 3323 of multiple specifications, thus adapting to shock absorber products of different specifications. The connecting plate a3314 and the pressure plate 3322 are then fixedly installed by the positioning bolt 3326, making the pressing position controllable. This allows for rapid switching between multi-variety, small-batch production modes, enabling the production line to quickly respond to changes in market orders and reduce equipment adjustment costs caused by product iterations. This is especially suitable for customized production scenarios.

[0036] Furthermore, such as Figure 6 As shown, the tooling 2 includes a pallet 21, a support column b22 mounted on the pallet 21, and pneumatic grippers 23 mounted on the pallet 21 and symmetrically arranged on both sides of the support column b22.

[0037] It should be noted that the pneumatic gripper 23 is used to clamp and fix the shock absorber installed on the support column b22.

[0038] Example 2 like Figure 6 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 6 As shown, as described. Further, as... Figure 5 As shown, the clamping assembly 34 includes two sets of clamping members 341 symmetrically arranged on both sides of the positioning member 332 and movable relative to each other. Each clamping member 341 includes a guide rail b3411 installed on the lower surface of the lifting plate 311, a guide seat b3412 slidably arranged on the guide rail b3411, a connecting plate b3413 connected to the guide seat b3412, and an annular block 3414 connected to the inner side of the connecting plate b3413. The guide seat b3412 is driven vertically by a pneumatic unit b3415.

[0039] In this embodiment, by setting a clamping component 34 to fit and clamp the outer periphery of the spring and move down synchronously with the lifting plate 311, the clamping component 34 completes real-time limiting of the spring during the spring compression process, preventing the spring from shifting during the active state, ensuring the coaxial structure of the spring and the upper support, and improving the consistency of the shock absorber performance.

[0040] Specifically, when the pressure head 3323 acts on the end cap, the pneumatic unit b3415 is activated, the guide seat b3412 moves along the guide rail b3411, and the annular block 3414 on the connecting plate b3413 moves toward the spring. The two sets of annular blocks 3414 move relative to each other to hold the spring. The movement distance can be adjusted in real time according to the size of the spring.

[0041] Work process After the tooling 2 is loaded with accessories, the shock absorber is transferred to the pressing station. The transmission component drives the sliding component to descend. The upper support passes through the pressure plate. The pneumatic unit a of the guide 331 is activated. The pressure plate acts on the end cover of the shock absorber. Next, the clamping assembly is activated, the two sets of annular blocks clamp the spring, the transmission assembly drives the sliding assembly to descend again, the end cover presses down to compress the spring, the upper end of the upper support passes through the positioning groove, and the nut is manually pre-tightened onto the upper support of the shock absorber.
