Description

Technical Field

[0001] This utility model mainly relates to the field of automotive parts manufacturing technology, specifically a wax-coated valve disc riveting mechanism. Background Technology

[0002] In automotive engine cooling systems, the thermostat is a core functional component. It ensures that the engine is always kept in the optimal operating temperature range by precisely adjusting the water circulation path of the cooling system. In the field of automotive parts manufacturing, especially in the production of thermostats for engine cooling systems, the assembly and riveting process of valve discs and seals is particularly critical.

[0003] In existing technologies, during the assembly and riveting process of valve discs and sealing rings, the sealing rings are prone to floating during operation due to missing positioning structures or uneven distribution of riveting force, leading to the scrapping of the entire component. Furthermore, traditional sealing ring installation methods often rely on manual assembly or rigid mechanical pressing. Due to the subjectivity of manual operation and the limitations of rigid structures, it is difficult to accurately control the installation force and depth, resulting in incomplete installation of the sealing rings. Even with rigid machinery, uneven pressure distribution can cause excessive localized stress and deformation of the sealing ring, severely affecting sealing performance. However, in applications with extremely high requirements for sealing ring installation, the sealing ring must be fully installed to ensure the equipment's sealing and reliability. This forces operators to repeatedly check and adjust to ensure installation quality, significantly reducing production efficiency. Therefore, a wax-coated valve disc riveting mechanism is needed. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a wax-coated valve disc riveting mechanism to solve the technical problem mentioned in the background that the installation of the sealing ring during assembly and riveting work is highly demanding and requires complete installation, which reduces work efficiency.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A wax-coated valve disc riveting mechanism includes an upper fixed cover for a fixture, a fixture housing installed at the bottom of the upper fixed cover, a sealing ring clamping fixture installed inside the fixture housing via a clamping fixture positioning sleeve, a spring positioning core installed inside the sealing ring clamping fixture, a spring installed at the bottom of the upper fixed cover, a lower fixed cover for a fixture installed at the bottom of the fixture housing, a valve disc positioning fixture located below the lower fixed cover, and a valve disc riveting forming fixture fitted to the inner wall of the lower fixed cover.

[0007] More preferably, the upper outer wall of the upper fixing cover of the tooling is provided with a circular hole, and the top of the upper fixing cover of the tooling and the top of the middle part of the tooling shell are provided with a plurality of screw holes distributed in a ring, and the top of the lower fixing cover of the tooling and the bottom of the tooling shell are provided with a plurality of screw holes distributed in a ring.

[0008] More preferably, the sealing ring clamping fixture is slidably installed inside the clamping fixture positioning sleeve, and its cross-sectional shape is designed as a T-shaped structure.

[0009] More preferably, the spring positioning core is T-shaped, and the top of the spring positioning core is connected to one end of the spring.

[0010] More preferably, the bottom of the tooling housing and the top of the tooling lower fixing cover are both provided with annular grooves for snapping the valve disc into a riveting tooling.

[0011] In a further preferred embodiment, the bottom of the lower fixing cover of the tooling has an insertion hole corresponding to the upper part of the valve disc positioning tooling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This wax-coated valve disc riveting mechanism, through a disc positioning fixture, a valve disc riveting forming fixture, and a sealing ring clamping fixture, works as follows: when the fixture is moved downward by the equipment, the sealing ring clamping fixture, spring positioning core, and spring cooperate, with the spring providing elastic force, causing the sealing ring clamping fixture to press against the sealing ring. Subsequently, the valve disc riveting forming fixture directly rivets the valve disc. Compared to the traditional assembly and riveting process of valve disc and sealing ring, this structure is suitable for fixtures that integrally form valve discs, which can improve the efficiency of valve disc and sealing ring assembly and riveting.

[0022] Please refer to the appendix carefully. Figure 1-3 A wax-coated valve disc riveting mechanism includes an upper fixed cover 1, a fixture housing 2 installed at the bottom of the upper fixed cover 1, a sealing ring clamping fixture 4 installed inside the fixture housing 2 via a clamping fixture positioning sleeve 7, a spring positioning core 3 installed inside the sealing ring clamping fixture 4, a spring 6 installed at the bottom of the upper fixed cover 1, a lower fixed cover 8 installed at the bottom of the fixture housing 2, a valve disc positioning fixture 9 located below the lower fixed cover 8, and a valve disc riveting forming fixture 5 attached to the inner wall of the lower fixed cover 8.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the upper outer wall of the upper fixed cover 1 of the tooling is provided with a round hole, and the top of the upper fixed cover 1 of the tooling and the top of the middle part of the tooling shell 2 are provided with several screw holes arranged in a ring. The top of the lower fixed cover 8 of the tooling and the bottom of the tooling shell 2 are provided with several screw holes arranged in a ring. The upper fixed cover 1 of the tooling and the tooling shell 2 can be installed with the tooling shell 2 and the tooling shell 2 can be installed with the lower fixed cover 8 of the tooling. When maintenance is required, the upper fixed cover 1 and the lower fixed cover 8 of the tooling shell 2 can be removed to maintain or replace the internal components of the mechanism.

[0024] In this embodiment, as Figure 2 and Figure 3 As shown, the sealing ring clamping fixture 4 is slidably installed inside the clamping fixture positioning sleeve 7, and its cross-sectional shape is designed as a T-shaped structure; the clamping fixture positioning sleeve 7 is used to guide the sealing ring clamping fixture 4 when the mechanism is in use, and the sealing ring clamping fixture 4 is used to clamp the sealing ring when the mechanism is in use.

[0025] In this embodiment, as Figure 2 and Figure 3As shown, the spring positioning core 3 is T-shaped, and the top of the spring positioning core 3 is connected to one end of the spring 6; the spring positioning core 3 is used to position the spring 6 and provide guidance for the spring 6. When the mechanism is in use, it provides elastic force by compressing the spring 6 to press the sealing ring.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, the bottom of the tooling housing 2 and the top of the tooling lower fixed cover 8 are both provided with annular grooves for snapping the valve disc into the riveting tooling 5; the tooling housing 2 is used to install the internal structure, and the snapping valve disc into the riveting tooling 5 can be used to rivet the valve disc flange when the mechanism is in use.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the bottom of the lower fixed cover 8 of the fixture has an insertion hole corresponding to the upper part of the valve disc positioning fixture 9; the tolerance requirement between the valve disc positioning fixture 9 and the insertion hole of the lower fixed cover 8 is ≤0.05mm. The top of the valve disc positioning fixture 9 has a positioning groove for placing the product. The valve disc positioning fixture 9 is used for product placement and positioning. When the mechanism is in use, the valve disc positioning fixture 9 can be stably inserted through the through hole at the bottom of the lower fixed cover 8 of the fixture, which improves the stability of the mechanism during use.

[0028] The specific operating procedure of this utility is as follows: First, the sealing ring is installed into the valve disc and placed on the valve disc positioning fixture 9. Then, after the equipment detects the product, the equipment drives the entire fixture set consisting of the upper fixing cover 1, the fixture shell 2, the spring positioning core 3, the sealing ring clamping fixture 4, the valve disc pressing and forming fixture 5, the spring 6, the clamping fixture positioning sleeve 7, and the lower fixing cover 8 to press down. The sealing ring clamping fixture 4 first contacts the sealing ring. The spring 6 is compressed and provides elastic force to the sealing ring clamping fixture 4 through the spring positioning core 3, so that the sealing ring clamping fixture 4 clamps the sealing ring. Then, the valve disc pressing and forming fixture 5 presses and forms the valve disc. After the valve disc pressing and forming fixture 5 contacts the valve disc positioning fixture 9, the pressing is completed, and the product processing is finished.

[0029] During processing, an elastic clamping system is formed by spring 6, spring positioning core 3, and sealing ring clamping fixture 4. When the entire fixture is pressed down, the elastic force generated by the compression of spring 6 is transmitted to the sealing ring clamping fixture 4 through spring positioning core 3. This elastic pressure has self-adjusting capability, and can continuously apply stable and uniform pressure during the contact of the sealing ring with the mounting surface, prompting the sealing ring to overcome the installation resistance until it is fully installed. Compared with traditional rigid structures, this elastic system avoids the situation where the sealing ring is damaged due to excessive instantaneous rigid pressure, or the situation where the pressure is insufficient to install it properly. Through the buffering and continuous pressure characteristics of spring 6, the installation accuracy and reliability are significantly improved while ensuring the installation quality of the sealing ring.

[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
