Description

Technical Field

[0001] This utility model relates to the field of installation tooling technology, specifically to a riveting device, an air compressor, and an air suspension system. Background Technology

[0002] Air suspension systems have solenoid valves for controlling airflow. In related technologies, solenoid valves are typically assembled using riveting or welding. Riveting often uses a single-piece pressure head to rivet the solenoid valve. However, due to the wide variety of solenoid valve specifications, changing the solenoid valve specification requires replacing the entire tooling with the single-piece pressure head, leading to difficulties in replacement, repeated adjustments, time-consuming and labor-intensive processes, and potential instability in pre-pressure. This hinders large-scale production and reduces the likelihood of achieving assembly accuracy. Utility Model Content

[0003] In view of this, the present invention provides a riveting device, an air compressor and an air suspension system to solve the problem of difficult tooling replacement and repeated debugging required when using an integrated riveting head.

[0004] In a first aspect, this utility model provides a riveting device, comprising:

[0005] The base includes a connection portion suitable for connection with a riveting device, and a pressure head mounting portion;

[0006] The pressure head is suitable for detachable connection with the pressure head mounting part, and the pressure head is suitable for press-fitting the solenoid valve;

[0007] A fastener is inserted into the pressure head mounting part to lock or unlock the pressure head from the pressure head mounting part.

[0008] Beneficial effects: The riveting device provided in the embodiments of this utility model has a base and a pressure head as separate structures. Therefore, after the base is connected to the riveting equipment, there is no need for frequent replacement and disassembly. Only different specifications of pressure heads need to be replaced to meet the riveting requirements of various solenoid valves. The pressure head can be quickly replaced for different solenoid valve specifications without disassembling the entire tooling, reducing tooling replacement costs. There is no need for repeated debugging, ensuring the stability and reliability of the solenoid valve pre-pressurization state, and improving assembly accuracy and efficiency.

[0009] In one optional embodiment, the pressure head mounting part has a mounting cavity inside, and a first opening is formed at one end of the pressure head mounting part away from the connecting part. The first opening is adapted to communicate with the mounting cavity; the pressure head passes through the first opening into the mounting cavity.

[0010] Beneficial effects: By opening an installation cavity inside the pressure head mounting part, the connection between the pressure head mounting part and the pressure head is ensured to be tight, avoiding detachment due to vibration. At the same time, the installation cavity plays a guiding and positioning role in the assembly process of the pressure head, making the installation and disassembly of the pressure head more convenient.

[0011] In one optional embodiment, the pressure head mounting part is further provided with a through hole, the axis of the through hole is set at an angle to the axis of the mounting cavity, and the through hole is connected to the mounting cavity.

[0012] The fastener is suitable for insertion into the pressure head mounting part through the perforation.

[0013] Beneficial effects: The perforated design allows the fastener to be inserted into the pressure head mounting part at a specific angle, which constrains and guides the installation of the fastener, thereby ensuring the precise relative position of the fastener and the pressure head, enhancing the stability of the overall structure, and further optimizing the riveting effect.

[0014] In one alternative embodiment, the pressure head mounting portion is partially formed into a protrusion, and a through hole is formed in the protrusion.

[0015] Beneficial effects: By creating a raised section in the mounting part of the pressure head and placing the perforation within this raised section, the structural strength is enhanced, ensuring that the perforation is not easily deformed under stress. This further improves the installation stability of the fastener, optimizes the mechanical distribution during the riveting process, and makes the overall assembly more robust and reliable. The raised section design also facilitates the rapid positioning of the fastener, reducing assembly time and improving production efficiency.

[0016] In one optional embodiment, the pressure head has an assembly cavity inside, and a second opening is formed at the end of the pressure head away from the connecting part. The second opening is adapted to communicate with the assembly cavity. A solenoid valve with matching specifications and model is adapted to be installed in the assembly cavity.

[0017] Beneficial effects: The pressure head has an assembly cavity inside, which is suitable for installing a solenoid valve with matching specifications and model. This allows the solenoid valve to be accurately embedded, ensuring a tight fit between the solenoid valve and the pressure head. The assembly cavity provides a stable support environment for the assembly of the solenoid valve, preventing the solenoid valve from tilting or shifting during the riveting process. This provides a stable installation environment and improves the stability and accuracy of the riveting process.

[0018] In one alternative embodiment, the riveting device further includes a spring disposed within the assembly cavity and having an interference fit with the assembly cavity.

[0019] Beneficial effects: By setting a spring in the assembly cavity of the pressure head, a tight interference fit between the spring and the assembly cavity of the pressure head is achieved, ensuring that the spring provides stable elastic support during the riveting process, effectively buffering vibration, preventing displacement of the solenoid valve, and further optimizing the riveting effect. This ensures that the solenoid valve will not bounce upward due to the deformation of the sealing ring when riveting the solenoid valve, ensuring that the solenoid valve is airtight inside the valve block. Furthermore, the interference fit ensures that the spring will not detach from the pressure head during assembly.

[0020] In one alternative embodiment, the connecting portion is formed with a fixing hole through it, the fixing hole being adapted to insert a mounting component, and the connecting portion and the riveting device being adapted to be connected via the mounting component.

[0021] Beneficial effects: Ensures a secure and reliable connection between the joint and the riveting equipment, prevents loosening during the riveting process, and further enhances the stability and safety of the overall structure.

[0022] In one alternative embodiment, the fastener includes a bolt, and an internal thread is formed inside the hole corresponding to the bolt.

[0023] Beneficial effects: By creating internal threads inside the perforation corresponding to the bolt, the bolt engages tightly after being screwed into the perforation, ensuring it does not fall out. When replacing the pressure head, it is not necessary to completely remove the bolts; simply loosening the bolts allows for easy disassembly and replacement of the pressure head, simplifying the maintenance process and improving work efficiency.

[0024] Secondly, this utility model also provides an air compressor, comprising:

[0025] A valve block with a solenoid valve mounting hole;

[0026] Solenoid valve, suitable for assembly into solenoid valve mounting hole;

[0027] The solenoid valve is suitable for installation via a crimping device as described above.

[0028] Beneficial effects: The press-fit device can reliably press the solenoid valve into the solenoid valve mounting hole, ensuring a tight fit between the solenoid valve and the valve block, improving the working efficiency and airtightness of the air compressor, and extending the service life of the equipment.

[0029] Thirdly, this utility model also provides an air suspension system, comprising:

[0030] Air spring;

[0031] And an air compressor, as described above, connected to an air spring.

[0032] Since the air suspension system includes an air compressor and has the same effect as an air compressor, it will not be elaborated on here. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0045] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] An air suspension system relies on compressed air to control the air springs between the wheels and the vehicle body. When the vehicle's load changes, the air suspension system needs to adjust the amount of air in the air springs to adjust the vehicle's height. The air suspension system has solenoid valves that control the airflow. Coils influence the state of the solenoid valve spool, thereby controlling the airflow and precisely regulating the air compressor's charging, pressure regulation, and exhaust processes to achieve the various functions of the air suspension system.

[0047] In related technologies, solenoid valves are usually assembled by riveting or welding. Riveting often uses an integrated pressure head to rivet the solenoid valve. However, since solenoid valves come in a variety of specifications, the tooling with the integrated pressure head needs to be replaced as a whole after the solenoid valve specifications are changed. This makes replacement difficult and requires repeated debugging, which is time-consuming and labor-intensive and can easily cause unstable pre-pressure. This is not conducive to large-scale production and to ensuring assembly accuracy.

[0048] The riveting device provided in the embodiments of this utility model adopts a split-type pressure head, which can quickly change the pressure head for different solenoid valve specifications without disassembling the entire tooling, reducing tooling replacement costs, eliminating the need for repeated debugging, ensuring the stability and reliability of the solenoid valve pre-pressurization state, and improving assembly accuracy and efficiency.

[0049] The following is combined with Figures 1 to 4The following describes embodiments of the present invention.

[0050] According to an embodiment of the present invention, in one aspect, a riveting device is provided, comprising:

[0051] The base 1 includes a connecting part 11 adapted to be connected to a riveting device, and a pressure head mounting part 12;

[0052] The pressure head 2 is adapted to be detachably connected to the pressure head mounting part 12, and the pressure head 2 is adapted to press-fit the solenoid valve 6.

[0053] The fastener 4 is inserted into the pressure head mounting part 12 to lock or unlock the pressure head 2 to the pressure head mounting part 12.

[0054] The base 1 includes a connecting part 11 and a pressure head mounting part 12. The base 1 can be an integral structure or a split structure. In this embodiment, the base 1 adopts an integral structure.

[0055] The connecting part 11 is adapted to be connected to the riveting equipment, thereby fixing the entire riveting device on the riveting equipment. Under the drive of the riveting equipment, the entire riveting device moves, thereby facilitating the precise riveting of the solenoid valve and ensuring the stability of the riveting process.

[0056] In this embodiment, the base 1 and the pressure head 2 are separate structures.

[0057] The pressure head mounting part 12 is used to mount the pressure head 2, which can be a pressure head 2 of different specifications and models, so that the riveting device can be adapted to the solenoid valve 6 of different specifications. The pressure head 2 is connected to the pressure head mounting part 12 by a detachable connection, which facilitates quick replacement. In this embodiment, the pressure head 2 and the pressure head mounting part 12 can be locked or unlocked by a fastener 4. The fastener 4 can be a bolt, pin, clip, or other fastener. On the one hand, it can realize quick installation and removal of the pressure head 2, and on the other hand, it can ensure that the pressure head 2 is stable and does not move during the riveting process, improve the riveting accuracy, and ensure that the height of the solenoid valve meets the process standard after the riveting is completed.

[0058] In this embodiment, the fastener 4 is in the form of bolts, which makes it easy to replace and ensures that the pressure head 2 will not fall off during assembly.

[0059] The locking or unlocking function of the fixing component 4 enables quick replacement of the pressure head 2, ensuring the flexibility and efficiency of the riveting process. This improves the adaptability of the riveting device, eliminating the need to design different tooling for different specifications of solenoid valves, thereby significantly reducing costs, increasing the efficiency of the riveting device, minimizing downtime, and adapting to diverse production needs.

[0060] In this embodiment, the pressure head mounting part 12 is designed as a universal type, meaning that the pressure head mounting part 12 can have only one specification. Therefore, after connecting the base 1 to the riveting equipment, frequent replacement and disassembly are unnecessary; simply replacing the pressure head 2 with a different specification can meet the riveting requirements of various solenoid valves 6, simplifying the operation process and improving production efficiency. Specifically, the inner diameter of the pressure head mounting part 12 can match the outer diameter of different specifications of pressure heads 2, while the outer diameter of different specifications of pressure heads 2 is a uniform size. By changing the inner diameter of the pressure head 2, the size of different solenoid valves 6 can be adapted.

[0061] In related technologies, tooling using an integrated pressure head requires replacement of the entire unit, leading to difficulties in replacement, repeated adjustments, and wasting time and effort, while also potentially causing unstable pre-compression. In this embodiment, the base 1 and pressure head 2 are designed as separate units, avoiding the cumbersome process of replacing the entire unit. Only pressure head 2 needs to be replaced, simplifying the adjustment process, ensuring pre-compression stability, and improving work efficiency and riveting quality. Furthermore, the pressure head mounting part 12 matches the outer diameter of pressure heads 2 of different specifications, reducing equipment adjustment time and improving assembly accuracy and efficiency.

[0062] The specific installation location of the solenoid valve 6 can be the solenoid valve mounting hole 51 of the valve block 5. In this embodiment, the pressure head 2 can be made of steel to ensure that the deformation of the valve block 5 under pressure tightly wraps the solenoid valve 6, ensuring that the solenoid valve and the valve block are airtight.

[0063] In some embodiments, combined with Figure 2 , Figure 5 As shown, the pressure head mounting part 12 has a mounting cavity 122 inside, and a first opening 121 is formed at the end of the pressure head mounting part 12 away from the connecting part 11. The first opening 121 is adapted to communicate with the mounting cavity 122; the pressure head 2 passes through the first opening 121 into the mounting cavity 122.

[0064] The pressure head 2 is inserted into the mounting cavity 122 through the first opening 121 and fixed by a locking device to ensure that the connection between the pressure head 2 and the pressure head mounting part 12 is firm and to prevent loosening.

[0065] By opening an installation cavity 122 inside the pressure head mounting part 12, the connection between the pressure head mounting part 12 and the pressure head 2 is ensured to be tight, avoiding detachment due to vibration. At the same time, the installation cavity 122 plays a guiding and positioning role in the assembly process of the pressure head 2, making the installation and disassembly of the pressure head 2 more convenient.

[0066] In some embodiments, the pressure head mounting portion 12 is further provided with a through hole 13, the axis of the through hole 13 is set at an angle to the axis of the mounting cavity 122, and the through hole 13 is connected to the mounting cavity 122.

[0067] The fastener 4 is adapted to be inserted into the pressure head mounting part 12 through the perforation 13.

[0068] The design of the perforation 13 allows the fastener 4 to be inserted into the pressure head mounting part 12 at a specific angle, which constrains and guides the installation of the fastener 4, thereby ensuring the precise relative position of the fastener 4 and the pressure head 2, enhancing the stability of the overall structure, and further optimizing the riveting effect.

[0069] In this embodiment, the axis of the perforation 13 is perpendicular to the axis of the mounting cavity 122, ensuring that the fastener 4 is subjected to uniform force when installed, avoiding skewing and improving assembly accuracy.

[0070] In some embodiments, the pressure head mounting portion 12 is partially formed into a protrusion, and a through hole 13 is formed in the protrusion.

[0071] By creating a protrusion in the pressure head mounting portion 12 and placing the through hole 13 within the protrusion, the structural strength is enhanced, ensuring that the through hole 13 is not easily deformed under stress. This further improves the installation stability of the fastener 4, optimizes the mechanical distribution during the riveting process, and makes the overall assembly more robust and reliable. The protrusion design also facilitates the rapid positioning of the fastener 4, reducing assembly time and improving production efficiency.

[0072] In addition, the protrusion increases the contact area between the perforation 13 and the fastener 4. When replacing the pressure head 2, it is not necessary to completely remove the fastener 4 from the perforation 13. The fastener 4 can be quickly disassembled and assembled by using the constraint of the perforation 13 on the fastener 4.

[0073] In some embodiments, the pressure head 2 has an assembly cavity 22 inside, and a second opening 21 is formed at one end of the pressure head 2 away from the connecting part 11. The second opening 21 is adapted to communicate with the assembly cavity 22. The assembly cavity 22 is adapted to accommodate a solenoid valve 6 with matching specifications and model.

[0074] The pressure head 2 has an assembly cavity 22 inside, which is suitable for installing a solenoid valve 6 with matching specifications and model, so that the solenoid valve 6 can be accurately embedded, ensuring a tight fit between the solenoid valve 6 and the pressure head 2. The assembly cavity 22 can provide a stable support environment for the assembly of the solenoid valve 6, preventing the solenoid valve 6 from tilting or shifting during the riveting process, providing a stable installation environment, and improving the stability and accuracy of the riveting.

[0075] In some embodiments, the riveting device further includes a spring 3, which is disposed in the assembly cavity 22 and is interference-fitted with the assembly cavity 22.

[0076] By setting a spring 3 in the assembly cavity 22 of the pressure head 2, a tight interference fit between the spring 3 and the assembly cavity 22 of the pressure head 2 is achieved. This ensures that the spring 3 provides stable elastic support during the riveting process, effectively buffers vibration, prevents displacement of the solenoid valve 6, and further optimizes the riveting effect. This ensures that the solenoid valve 6 will not bounce upward due to the deformation of the sealing ring 7 when riveting the solenoid valve 6, ensuring that the solenoid valve 6 is airtight inside the valve block 5. Furthermore, the interference fit ensures that the spring 3 will not detach from the pressure head during assembly.

[0077] Combination Figure 5 As shown, a sealing ring 7 is provided at the bottom of the solenoid valve 6 where it contacts the valve block 5. The sealing ring 7 is compressed during the riveting process to form a reliable sealing interface, ensuring the airtightness between the solenoid valve 6 and the valve block 5 and preventing gas leakage.

[0078] In some embodiments, combined with Figure 5 As shown, the connecting part 11 has a through-hole 111, and the mounting part is adapted to be inserted into the mounting part 111. The connecting part 11 is adapted to be connected to the riveting device via the mounting part.

[0079] The mounting component can be a bolt. By inserting the bolt into the fixing hole 111 and tightly connecting it with the riveting equipment, the connection part 11 is ensured to be firmly and reliably assembled with the riveting equipment, preventing loosening during the riveting process and further improving the stability and safety of the overall structure.

[0080] In some embodiments, the fastener 4 includes a bolt, and the through hole 13 has an internal thread corresponding to the bolt.

[0081] By forming internal threads inside the corresponding bolt in the through hole 13, the internal threads tightly engage after the bolt is screwed into the through hole 13, ensuring that the bolt does not fall out. When replacing the pressure head 2, it is not necessary to remove all the bolts; simply loosen the bolts to easily disassemble and replace the pressure head 2, simplifying the maintenance process and improving work efficiency.

[0082] According to an embodiment of the present invention, another aspect provides an air compressor, comprising:

[0083] Valve block 5, on which a solenoid valve mounting hole 51 is provided;

[0084] Solenoid valve 6 is suitable for assembly into solenoid valve mounting hole 51;

[0085] The solenoid valve 6 is suitable for installation via a crimping device as described above.

[0086] The press-fit device can reliably press the solenoid valve 6 into the solenoid valve mounting hole 51, ensuring that the solenoid valve 6 and the valve block 5 are tightly connected, improving the working efficiency and airtightness of the air compressor, and extending the service life of the equipment.

[0087] According to an embodiment of the present invention, in another aspect, an air suspension system is also provided, comprising:

[0088] Air spring;

[0089] And an air compressor, as described above, connected to an air spring.
