[0017] 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.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model provides the following technical solution:

[0020] As attached Figure 1-3As shown, this utility model discloses a press-fit fixture for the intake and exhaust valve core assembly of an EBS solenoid valve, including a base 1 and a press-fit bracket 2. The press-fit bracket 2 is mounted on the base 1, and a base 3 is disposed at the center of the base 1. A power source 4 and a press-fit mechanism 5 are mounted on the press-fit bracket 2. The power source 4 drives the press-fit mechanism 5 to perform a press-fit action on the press-fit bracket 2. The press-fit mechanism 5 includes a contouring press head 6 and an elastic press head 7. A press-fit groove 8 is formed on the contouring press head 6, and the press-fit groove 8 has a press-fit function. The unit consists of part 9 and mounting part 10. The elastic pressure head 7 is disposed in the mounting part 10. The pressing part 9 has a contoured pressing port 11 that communicates with the outside of the pressing groove 8. The housing 12 to be pressed is placed on the base 3. The valve cover 13 to be pressed is placed in the pressing part 9. During the process of the power source 4 driving the pressing mechanism 5 to press against the base 3, the elastic pressure head 7 presses the valve cover 13 to be pressed into the housing 12 to be pressed. The inner wall of the contoured pressing port 11 presses and closes the edge of the housing 12 to be pressed. Specifically, in this design, the housing 12 to be pressed and the valve cover 13 to be pressed are placed on the base 3 and the contouring head 6, respectively. Then, the power source 4 is activated to install the pressing fixture. During the pressing process, one end of the inner pressure head 17, located in the mounting part 10 of the pressing groove 8, extends into the pressing part 9 and connects to the valve cover 13 to be pressed. The bottom end of the valve cover 13 extends out of the pressing port. Therefore, when the valve cover 13 contacts the housing 12, the inner pressure head 17 pushes the valve cover 13 towards the housing 12 and presses it into the housing 12. At this time, the contouring head 6 is not in contact with the housing 12. Subsequently, the rectangular spring 16 continues to compress, causing the contouring head 6 to contact the housing 12 and close the edge of the housing 12, thus pressing the edge of the housing 12 tightly against the valve cover 13. This design has a simple structure, is easy to operate, and can effectively improve production efficiency and pressing quality. Furthermore, the combined design of the contouring pressure head 6 and the elastic pressure head 7 ensures higher alignment accuracy during the pressing process, reducing pressing defects caused by misalignment. Simultaneously, the elastic pressure head 7 absorbs some impact force, protecting the valve cover from damage. The pressing groove 8 design of the pressing mechanism 5 makes the pressing action more stable, avoiding shell deformation caused by uneven pressing. Overall, this pressing fixture is suitable for mass production, meeting the pressing requirements of EBS solenoid valve inlet and outlet valve core assemblies of different sizes and shapes, and exhibits good versatility and reliability.

[0021] Furthermore, the pressing mechanism 5 also includes a guide plate 14 and a power connector 15. The contour pressing head 6 is located at the center of the side end face of the guide plate 14 near the base 3. The elastic pressing head 7 includes a rectangular spring 16 and an inner pressing head 17 disposed within the mounting portion 10. The two ends of the rectangular spring 16 are connected to the guide plate 14 and the inner pressing head 17, respectively. The end of the inner pressing head 17 away from the rectangular spring 16 extends into the pressing portion 9 and abuts against the valve cover 13 to be pressed. Specifically, in this embodiment, the guide plate 14 ensures precise guidance of the contour pressing head 6, making the alignment during the pressing process more accurate, thereby improving the overall stability and repeatability of the pressing process. The power connector 15 is responsible for transmitting power to the contour pressing head 6 and the elastic pressing head 7, ensuring that they can work together to complete the pressing task. The use of the rectangular spring 16 provides the necessary elasticity for the inner pressing head 17, enabling it to adapt to valve covers 13 of different thicknesses and hardness during the pressing process, while absorbing the impact force generated during pressing and protecting the valve cover from damage. The internal pressure head 17 is designed to effectively and evenly apply pressure to the valve cover 13 to be press-fitted, ensuring the quality of the press-fitting process. This design enables the press-fitting mechanism 5 to precisely press-fit the EBS solenoid valve's inlet and outlet valve core assembly, meeting the demands for high efficiency and precision in mass production.

[0022] Furthermore, a connecting groove 18 is formed on the inner pressure head 17. One end of the valve cover 13 to be press-fitted extends into the connecting groove 18 and connects to the inner pressure head 17. A clamping sealing ring 19 is fixed in the connecting groove 18, and one end of the valve cover 13 to be press-fitted extends into the clamping sealing ring 19 and is interference-fitted with the clamping sealing ring 19. Specifically, in this embodiment, by setting the clamping sealing ring 19, the relative sliding between the valve cover and the inner pressure head 17 due to pressure during the press-fitting process can be effectively prevented, thereby ensuring the accuracy of the press-fitting.

[0023] Furthermore, a pad 20 is provided at the bottom of the contour pressing head 6, and a pad pressing port 21 corresponding to the contour pressing port 11 is provided on the pad 20. The pad pressing port 21 is connected to the contour pressing port 11. Specifically, in this embodiment, the pad 20 can further improve the adaptability and stability of the pressing process. Through the connection design between the pad pressing port 21 and the contour pressing port 11, it can be ensured that the pad 20 can deform accordingly according to the shape of the valve cover during the pressing process, thereby achieving precise pressing of the valve cover. This design not only improves the pressing efficiency but also reduces the pressing error caused by shape mismatch, ensuring the stability of the pressing quality.

[0024] Furthermore, the contouring indenter 6 has a fixing part 22, which is arranged in a ring shape. Bolts are provided between the fixing part 22 and the guide plate 14, and the fixing part 22 is fixed to the guide plate 14 by the bolts. Specifically, in this embodiment, the bolt fixing method ensures the stability of the contouring indenter 6 during the pressing process, while also facilitating maintenance and replacement. In addition, the ring-shaped fixing part 22 design can evenly distribute pressure, avoiding localized stress concentration, thereby extending the service life of the contouring indenter 6 and ensuring the continuity and reliability of the pressing process.

[0025] Furthermore, the pressing bracket 2 is provided with a guide rod 23, and a guide sleeve 24 is fitted onto the guide rod 23. The guide sleeve 24 has a guide end 25 and a guide plate connecting end 26. The guide plate 14 has a guide hole 28, and the guide end 25 extends into the guide hole 28 and connects to the guide plate 14. The guide plate connecting end 26 is fixed to the guide plate 14 by bolts. Specifically, in this embodiment, the guide sleeve 24 can effectively guide the movement trajectory during the pressing process and ensure the accuracy of the pressing. The cooperation between the guide rod 23 and the guide sleeve 24 makes the pressing bracket 2 more stable during operation and reduces errors caused by vibration or offset. At the same time, the tight fit between the guide end 25 of the guide sleeve 24 and the guide hole 28 ensures the smooth progress of the pressing process and avoids unnecessary friction and wear. In addition, the bolt connection between the guide plate and the guide plate 14 allows the entire structure to be quickly disassembled and adjusted when needed, improving the maintenance efficiency and adaptability of the equipment.

[0026] Furthermore, the power connector 15 is fixed at the center of the top of the guide plate 14. A push rod (not shown) is provided between the power connector 15 and the power source 4. The two ends of the push rod are connected to the power source 4 and the power connector 15, respectively. The power source 4 is a cylinder. Specifically, in this embodiment, the push rod can achieve precise reciprocating motion through the power provided by the cylinder, thereby driving the contouring press head 6 to perform pressing operations. The use of the cylinder not only improves the automation level of the operation, but also enables precise control of the pressing force and pressing depth by precisely controlling the thrust and stroke of the cylinder. In addition, compared with the traditional mechanical drive method, the cylinder as the power source 4 has advantages such as fast response speed, high control accuracy, and simple maintenance. In this embodiment, the design of the power connector 15 makes the connection between the push rod and the cylinder more robust and reliable, ensuring the stability and repeatability of the push rod 27 during continuous operation, thereby ensuring the efficiency and stability of the entire pressing process.
