Description

Technical Field

[0001] The utility model belongs to the technical field related to automotive shock absorbers, and particularly relates to a hydraulic top rubber stamping part riveting fixture. Background Technique

[0002] As an important shock-absorbing component, automotive shock absorbers have been widely used in various types of automobiles. When the automobile is driving and encounters potholes or stones, the automotive shock absorbers can effectively reduce and absorb the vibrations transmitted by the road surface. The top rubber device of the automotive shock absorber bracket can play the last shock-absorbing function when the road surface has a great impact on the shock absorber, so that there will be no hard collision between the automobile bodies, which may cause damage to the automobile, and can improve the stability and safety of automobile handling, reduce automobile noise, and enable passengers to have a good sense of comfort on uneven road surfaces.

[0003] At present, the top rubber in the shock absorber is a support structure installed on the shock absorber for connecting the vehicle body and is an important part of the automotive shock absorption system. Its working principle is to utilize the internal friction characteristics of rubber to absorb the vehicle body gravity and the impact energy generated by the road surface, so as to achieve the purpose of shock absorption. The existing top rubber needs to be installed with the stamping part of the bracket first, and then the stamping part of the bracket is connected to the vehicle frame through bolts. Therefore, the convex teeth on the stamping part of the bracket need to fasten the top rubber. If the convex teeth do not fasten and lock the top rubber, it is easy to cause the problem of insufficient press-fitting of the top rubber and leakage of liquid. This not only affects the processing quality of the top rubber product, but even causes internal interference during use, resulting in leakage of non-freezing liquid inside, affecting the stiffness of the top rubber product. At present, manual operation is generally adopted, resulting in low work efficiency, and it is easy to have insufficient force, resulting in insufficient firm riveting of the top rubber, which also leads to low assembly efficiency and easy scrapping problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hydraulic top rubber stamping part riveting fixture, which solves the problems that the existing stamping part of the bracket and the top rubber are pressed and combined manually, resulting in low work efficiency, and it is easy to have insufficient force, resulting in insufficient firm riveting of the top rubber, which also leads to low assembly efficiency and easy scrapping problems.

The part of the bottom of the top rubber installation groove relative to the outside of the extension cylinder communicates with the upper surface of the adjusting lifting seat. A lower die sliding column is slidably connected inside the extension cylinder. The upper part of the lower die sliding column is placed in the top rubber installation groove. A through hole is arranged at the center of the lower die sliding column. A top rubber spring positioning rod is arranged at the center of the upper surface of the bottom plate. The upper part of the top rubber spring positioning rod is inserted into the through hole of the lower die sliding column.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-3As shown in the figure, a riveting fixture for a hydraulic top mount stamping part disclosed in this embodiment includes a lifting mechanism 1, a press-in upper die 2, a lower die block positioning plate 3, and a bottom plate 4. Four die feet 5 are arranged on the bottom plate 4 in a front-back and left-right distribution. The lifting mechanism 1 is connected to the bottom plate 4 and drives the bottom plate 4 to move up and down. Above the four die feet 5, there is a lower die block positioning plate 3 parallel to the bottom plate 4. Inside the lower die block positioning plate 3, there is a trapezoidal guiding groove 6 located below the press-in upper die 2. Inside the trapezoidal guiding groove 6, there is a top mount positioning lower die block 7. Inside the top mount positioning lower die block 7, there is a top mount installation groove 8. At the center of the bottom of the top mount installation groove 8, there is an extension cylinder 9 extending vertically downward. Outside the extension cylinder 9, there is an adjusting lifting seat 10 threadedly connected. The part of the bottom of the top mount installation groove 8 relative to the outside of the extension cylinder 9 communicates with the upper surface of the adjusting lifting seat 10. Inside the extension cylinder 9, there is a lower die sliding column 11 slidably connected. The upper part of the lower die sliding column 11 is placed inside the top mount installation groove 8. The center of the lower die sliding column 11 is a through hole. At the center of the upper surface of the bottom plate 4, there is a top mount spring positioning rod 12. The upper part of the top mount spring positioning rod 12 is inserted into the through hole of the lower die sliding column 11. And a spring 13 is sleeved outside the top mount spring positioning rod 12, with one end abutted against the bottom of the lower die sliding column 11 and the other end abutted against the bottom plate 4. Outside the top mount positioning lower die block 7, there is a trapezoidal guiding part 14 cooperating with the inner wall of the trapezoidal guiding groove 6. On both sides above the lower die block positioning plate 3, there is a limit rod 15 respectively.

[0023] Preferably, the adjusting lifting seat 10 includes an adjusting seat 101. On the left and right sides of the adjusting seat 101, there is an inverted L-shaped top mount bottom limiting plate 102 inserted respectively. The vertical plate 1021 of the top mount bottom limiting plate 102 is inserted into the adjusting seat 101. The horizontal plate 1022 of the top mount bottom limiting plate 102 is parallel to the bottom of the top mount positioning lower die block 7. And there is a distance between the horizontal plate 1022 of the top mount bottom limiting plate 102 and the bottom of the top mount positioning lower die block 7. And the horizontal plate 1022 is flush with the upper surface of the adjusting seat 101 to form a top mount bottom limiting surface.

[0024] Preferably, for convenient height adjustment, there is an internal thread part 1011 inside the adjusting seat 101, and an external thread part 901 is arranged on the outside of the extension cylinder 9 to cooperate with the internal thread part 1011.

[0025] Preferably, the lifting mechanism 1 is a hydraulic cylinder, which can ensure a relatively large output pressure and make the press-fitting process more stable and reliable.

[0026] Preferably, to facilitate the later removal of the top rubber positioning lower die block 7, a handle 18 is respectively arranged on both sides above the top rubber positioning lower die block 7. By setting the handle 18, it is convenient to remove the entire top rubber positioning lower die block 7 from the trapezoidal guiding groove 6, and the positioning and guiding of the two are realized through the cooperation of the trapezoidal guiding groove 6 and the top rubber positioning lower die block 7 for the sliding frame connection.

[0027] When this structure works, the press-in upper die 2 can be fixed above a bracket, and the lifting mechanism 1 can be fixed below a bracket, and it is ensured that the press-in upper die 2 and the top rubber positioning lower die block 7 are symmetrically arranged up and down. The working principle of this equipment is as follows:

[0028] First, place the top rubber in the top rubber installation groove 8 in the top rubber lower die block positioning plate 3, ensure that the central through hole below the top rubber is stuck outside the lower die sliding column 11, then place the bracket stamping part in place above the top rubber. The press-in upper die 2 is positioned with the top rubber below through the press-in upper die positioning inner core 201 at the center of the press-in upper die 2. Then drive the lifting mechanism 1 to work, driving the bottom plate 4 to move up and down. When the bottom plate moves up, ensure that the press-in upper die positioning inner core 201 quickly presses into the top rubber installation groove 8, and finally press the convex teeth on the bracket stamping part and the top rubber together. Moreover, by using up and down centering press-in, accurate and consistent press-fitting in the required direction can be achieved, and the assembly efficiency is greatly improved compared with manual press-fitting. At the same time, during the press-fitting process, a spring is used to hold down the top rubber, effectively ensuring the stability of the non-tilting assembly when the top rubber is pressed in, ensuring the processing quality of the product and reducing the rejection rate. Later, when the external force of the lifting mechanism 1 disappears, through the action of the spring, the product is smoothly ejected, facilitating taking. Therefore, this structure is overall simple and reasonable, with a high assembly efficiency, a reduced rejection rate, and can effectively ensure the press-fitting direction and press-fitting force of the top rubber, ensuring the processing quality and manual production efficiency of the top rubber product, and also facilitating the later taking of the top rubber. And the adjusting lifting seat 10 is threadedly connected with the extension cylinder 9 to adjust the distance between the upper surface of the adjusting lifting seat 10 and the bottom of the top rubber installation groove 8 to fix top rubbers of different heights.

[0029] Embodiment 2

[0030] Please refer to Figure 4 As shown, the general structure of a hydraulic top rubber stamping part riveting fixture disclosed in this embodiment is the same as that in Embodiment 1. The difference is that, preferably, to avoid damaging the bottom of the top rubber, a silica gel wear-resistant layer 16 is arranged on the upper surface of the adjusting lifting seat 10. By setting the silica gel wear-resistant layer 16, when the top rubber is placed outside the extension cylinder 9 and the top of the top rubber contacts the silica gel wear-resistant layer 16, it is avoided that the top rubber is damaged due to hard contact with the upper surface of the adjusting lifting seat 10.
