[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] This utility model provides the following technical solution:

[0018] As attached Figure 1-2As shown, this utility model discloses a shock absorber block edge-expanding fixture, including a positioning unit 1 and at least two edge-expanding clamping units 2. A clamping station 3 is formed between the positioning unit 1 and the edge-expanding clamping units 2. A shock absorber block to be processed (not shown) is placed in the clamping station 3. The two edge-expanding clamping units 2 simultaneously press down on the shock absorber block to be processed to expand its edge. A support component 5 is provided on the positioning unit 1 to support the shock absorber block to be processed. Specifically, in this design, at least two edge-expanding clamping units 2 are arranged on the positioning unit 1, enabling simultaneous edge expansion of two shock absorbers on one side, significantly improving work efficiency. The support component 5 better stabilizes the shock absorber block to be processed, preventing displacement or deformation during the edge-expanding process, ensuring edge-expanding accuracy and product quality.

[0019] Furthermore, the positioning unit 1 includes a base plate 6, a column 7, and a positioning pin 8. The column 7 is located on both sides of the top of the base plate 6. A column through groove 9 is opened in the center of the column 7. One end of the positioning pin 8 extends into the positioning through groove and connects to the column 7. The other end of the positioning pin 8 passes through the damping block to be processed and connects to the edge-expanding and pressing unit 2. The support component 5 is set on the base plate 6. Specifically, in this embodiment, the positioning pin 8 on the column 7 is used to accurately position the damping block to be processed, ensuring that the edge-expanding and pressing unit 2 can accurately align with the damping block to be processed for edge-expanding operation. The design of the positioning pin 8 not only enhances the structural stability of the tooling but also effectively avoids errors caused by inaccurate positioning during edge-expanding, further improving the processing accuracy and consistency of the product. At the same time, the combination of the support component 5 and the base plate 6 provides a stable support foundation for the damping block to be processed. Even if a large pressure is generated during edge-expanding, the stability of the damping block to be processed can be maintained, effectively preventing unnecessary displacement or deformation.

[0020] Furthermore, the edge-expanding and clamping unit 2 includes a power source (not shown), an upper pressure head 10, and an edge-expanding pressure head 11. The two ends of the upper pressure head 10 are connected to the power source and the edge-expanding pressure head 11, respectively. The edge-expanding pressure head 11 has positioning holes 12 corresponding to positioning pins 8. One end of the positioning pin 8 passes through the damping block to be processed and extends into the positioning hole 12 to connect with the edge-expanding pressure head 11. The bottom end of the edge-expanding pressure head 11 clamps the damping block to be processed. Specifically, in this embodiment, the power source is a cylinder, which can drive the upper pressure head 10 and the edge-expanding pressure head 11 to move up and down, realizing the clamping and edge-expanding operation of the damping block to be processed. In addition, the positioning hole 12 allows the edge-expanding pressure head 11 to be precisely positioned on the damping block to be processed, ensuring the consistency and accuracy of the edge expansion. Simultaneously, the cooperative design of the column through-slot 9 and the positioning pin 8 allows the edge-expanding and clamping unit 2 to be flexibly adjusted according to different specifications of damping blocks to be processed, improving the versatility and adaptability of the tooling.

[0021] Furthermore, the expanding pressure head 11 includes a pressure head body 13 and a bushing 14. The pressure head body 13 has a bushing mounting portion 15 and an upper pressure head connecting portion 16. The bushing 14 is fitted onto the bushing mounting portion 15, and the outer diameter of the bushing 14 is the same as the outer diameter of the upper pressure head connecting portion 16. A sealing ring 17 is provided between the bushing 14 and the upper pressure head connecting portion 16. The bushing 14 presses the sealing ring 17 tightly onto the upper pressure head connecting portion 16, and the two ends of the sealing ring 17 are respectively sealed to the upper pressure head connecting portion 16 and the bushing 14. Specifically, in this embodiment, this design of the expanding pressure head 11 not only ensures the uniformity and stability of the pressing, but also effectively prevents liquid or gas leakage problems that may occur during the expanding process through the setting of the sealing ring 17, thereby improving the working efficiency and safety of the tooling. In addition, the detachable design between the bushing 14 and the pressure head body 13 facilitates replacement and maintenance, reducing maintenance costs under long-term use. Meanwhile, the use of bushing 14 increases the contact area between the edge-expanding pressure head 11 and the damping block to be processed, further improving the edge-expanding effect and product quality.

[0022] Furthermore, a connecting plate 18 is provided between the upper pressure head connecting part 16 and the upper pressure head 10. A fastening screw 19 is provided between the connecting plate 18 and the upper pressure head 10 and is fixed to the upper pressure head 10 by the fastening screw 19. The upper pressure head connecting part 16 of the pressure head body 13 is connected to the connecting plate 18. Specifically, in this embodiment, the design of the connecting plate 18 not only enhances the connection stability between the edge-expanding pressure head 11 and the upper pressure head 10, but also facilitates the replacement or maintenance of the edge-expanding pressure head 11, improving the flexibility and practicality of the tooling. In addition, the use of the fastening screw 19 ensures a tight fixation between the connecting plate 18 and the upper pressure head 10, preventing the edge-expanding effect from being affected by loosening during the edge-expanding process.

[0023] Furthermore, the support assembly 5 includes a compression spring 20, a guide pad 21, and a support pad 22. The guide pad 21 is fixed to the base plate 6, and a spring groove 23 is formed in the center of the guide pad 21. The compression spring 20 is disposed in the spring groove 23, with one end of the compression spring 20 abutting against the base plate 6 and the other end connected to the support pad 22. The top of the support pad 22 abuts against the shock-absorbing block to be processed. Specifically, in this embodiment, the design of the guide pad 21 not only provides guidance for the compression spring 20 but also ensures the stable movement of the support pad 22 in the vertical direction, avoiding lateral displacement and further enhancing stability during the edge-expanding process. The support pad 22 is preferably made of a wear-resistant and elastic material, which can effectively support the shock-absorbing block to be processed and absorb the impact force during the edge-expanding process to a certain extent, protecting the shock-absorbing block from damage. In addition, the height of the support component 5 can be flexibly adjusted by adjusting the preload of the compression spring 20 to accommodate the expansion requirements of shock absorber blocks of different sizes or types, thereby improving the versatility and adaptability of the tooling.
