[0028] The upper part of the press-fitting space is provided with an upper punch 3 which can move up and down, the bottom of the upper punch 3 is provided with a clamping device which can install the bushing, the clamping device can clamp and fix the bushing, so as to ensure that the bushing can be correctly and stably placed at the specified position during the press-fitting process. In short, the upper punch 3 and the clamping device at the bottom thereof jointly ensure that the bushing can be accurately and firmly press-fitted on the shock absorber.

[0029] The lower part of the press-fitting space is provided with a bottom sleeve 10 for installing the shock absorber shell, the upper punch 3 can drive the bushing to move downward and insert into the inside of the shock absorber shell, when the press-fitting program is started, the upper punch 3 will drive the bushing to move downward until the bushing is accurately inserted into the inside of the shock absorber shell. This design ensures that the bushing can be accurately and efficiently installed on the shock absorber, the inside of the bottom sleeve 10 is provided with a mounting hole which is matched with the shock absorber shell, the inside of the bottom sleeve 10 is provided with a mounting hole which is matched with the shock absorber shell, and the mounting hole ensures that the shock absorber shell can be stably and accurately placed on the bottom sleeve 10.

[0030] A guide ring 6 is arranged between the upper punch 3 and the bottom sleeve 10, and adheres to the upper end of the shock absorber shell when the shock absorber shell is arranged inside the bottom sleeve 10. The inner side of the guide ring 6 is provided with a tapered surface, which is in the shape of an upper flared lower tapered surface. The diameter of the lower tapered surface is less than or equal to the inner diameter of the pipe opening of the shock absorber, and the diameter of the upper flared surface is greater than the outer diameter of the pipe opening of the bushing. Such a design ensures that the bushing can smoothly and accurately enter the shock absorber shell during the pressing process, and also plays a guiding and positioning role, improving the precision of the pressing.

[0031] Embodiment Two

[0032] As Figures 1-6 shown, on the basis of Embodiment One, this embodiment provides the function of the guide ring 6, which is as follows:

[0033] The guide ring 6 is a split structure, and includes a first clamping ring 61 and a second clamping ring 62. The first clamping ring 61 and the second clamping ring 62 can slide horizontally to the two sides. The guide ring 6 is designed as a split structure, including a first clamping ring 61 and a second clamping ring 62, which can slide horizontally to the two sides to accommodate the upper punch 3. When the pressing process starts, the upper punch 3 drives the end of the bushing to partially insert into the shock absorber shell, and the guide ring 6 is split to provide space for the upper punch 3 to continue to move downward. This split structure not only facilitates operation and adjustment, but also helps to more accurately guide and position the bushing during the pressing process, thereby ensuring that the entire pressing process can be smoothly carried out.

[0034] The side plates 4 are fixed on both sides of the chassis 1, and the oil cylinders are fixed on the side plates 4. The output ends of the oil cylinders are fixed with connecting plates 5, and the two connecting plates 5 are fixed with the first clamping ring 61 and the second clamping ring 62, respectively.

The side wall of the side plate 4 close to the connecting plate 5 is provided with an accommodation groove matched with the connecting plate 5. The side plate 4 close to the connecting plate 5 is provided with an accommodation groove, which is designed to provide sufficient movement space for the connecting plate 5 and the top ring 7 connected thereto when the guide ring 6 needs to be split, so as to ensure that the upper punch 3 can smoothly drive the bushing into the shock absorber shell.

[0035] Embodiment Three

[0036] As Figures 1-6Based on the embodiments one and two, the present embodiment provides the structure of the clamping device, which is as follows:

[0037] The clamping device comprises a top ring 7 fixed at the bottom of the upper punch 3, and the inner part of the top ring 7 is provided with a clamping groove for installing the bushing, which can be stably and accurately fixed on the upper punch 3, so as to be smoothly and accurately inserted into the shock absorber shell during the press fitting process.

[0038] A plurality of clamping balls 9 are arranged in the inner part of the top ring 7 in a circumferential direction, and the inner wall of the top ring 7 is provided with clamping holes matched with the clamping balls 9, and the clamping balls 9 are clamped in the inner part of the clamping balls 9 through the elastic body 8. When the bushing needs to be installed, the outer wall of the bushing will contact the clamping balls 9 and generate a certain pressure, so that the clamping balls 9 are inwardly retracted and elastically clamped on the outer wall of the bushing, thereby realizing the firm connection between the bushing and the top ring 7.

[0039] Working principle:

[0040] The shock absorber shell is installed in the mounting hole in the bottom sleeve 10 to ensure stability and accuracy. At the same time, the bushing is installed in the clamping groove of the clamping device, and the firm connection between the bushing and the top ring 7 is realized through the action of the clamping balls 9 and the elastic body 8.

[0041] The oil cylinder is started, and the oil cylinder piston is extended and retracted to push the upper punch 3 to move downward. During the movement, the guide ring 6 is tightly attached to the upper end of the shock absorber shell to play a guiding and positioning role. When the end part of the bushing is partially inserted into the shock absorber shell under the driving of the upper punch 3, the first clamping ring 61 and the second clamping ring 62 of the guide ring 6 will slide horizontally to the two sides and leave space to allow the upper punch 3 to continue to move downward.

[0042] With the continuous movement of the upper punch 3, the bushing is completely press fitted into the shock absorber shell. At this time, the oil cylinder stops working, and the upper punch 3 returns to the initial position. The guide ring 6 and the clamping device also return to the initial state, preparing for the next press fitting operation.

[0043] Finally, it should be pointed out that the above embodiments are only used to illustrate but not to limit the technical solutions of the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present utility model can still be modified or equivalently replaced without departing from the spirit and scope of the present utility model, and any modification or partial replacement should be covered in the scope of the claims of the present utility model.
