Description

Technical Field

[0001] This invention relates to the field of sealing ring installation equipment technology, specifically to a high-adaptability sealing ring installation equipment and its application in solenoid valve assembly. Background Technology

[0002] As a key component of solenoid valves, the sealing ring plays a crucial role in preventing media leakage. Its proper installation and good sealing performance are fundamental to the stable operation and precise control of the solenoid valve, directly affecting its overall performance and service life.

[0003] Currently, common solenoid valve sealing ring installation equipment typically employs a combination of a support structure and a jacking device. Specifically, the support structure is responsible for opening the sealing ring to be installed, and once its end reaches the installation position, the jacking device pushes the sealing ring off the support structure.

[0004] During the process of the jacking device ejecting the sealing ring, the sealing ring is in a passive state of being subjected to force on one side, which can lead to uneven stress and deformation. Furthermore, for the sake of the sealing ring's stability on the supporting structure, especially for sealing rings with a circular cross-section, it is generally not placed at the end of the supporting structure. This necessitates the sealing ring moving a certain distance on the supporting structure. During this sliding process, the sealing ring suffers structural damage due to deformation, which in turn affects the sealing effect of the subsequent solenoid valve, making it difficult to fully guarantee the product quality of the solenoid valve. Summary of the Invention

[0005] The purpose of this invention is to provide a highly adaptable sealing ring installation device and its application in solenoid valve assembly, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Parallel-arranged intermediate plate, connecting plate, and guide plate;

[0009] The extension arm is provided in multiple sets and is capable of moving along the radial direction of the guide plate;

[0010] An extension / retraction assembly is disposed between the connecting plate and the guide plate, and the extension / retraction assembly is capable of driving the extension arm to move along the radial direction of the guide plate;

[0011] A deflector is embedded in the extension arm, and the deflector is rotatably connected to the end of the extension arm away from the guide plate;

[0012] A support structure is connected to the deflector, which can drive the deflector to rotate relative to the extension arm so that the sealing ring fitted on the extension arm disengages.

[0013] As a further aspect of the present invention: the retracting and expanding assembly includes multiple sets of sliding grooves equidistantly arranged on the guide plate in a circular pattern, the sliding grooves facing the radial direction of the guide plate, and a slider slidably installed in the sliding groove, one side of the slider being fixedly connected to the extension arm, and the other side being rotatably mounted with a convex shaft;

[0014] The expansion and contraction assembly also includes a drive motor fixedly mounted on the intermediate plate. The output shaft of the drive motor is connected to a rotating assembly, and the rotating assembly is provided with multiple sets of inclined grooves that are tactilely connected to the convex shaft.

[0015] As a further aspect of the present invention: the inclined groove moves toward the center of the guide plate along its length direction, and when the inclined groove makes a circular motion, it can drive the convex shaft to slide along the length direction of the inclined groove.

[0016] As a further embodiment of the present invention: the rotating assembly includes multiple sets of grooved wheels arranged circumferentially at equal intervals on the guide plate, a rotating disk is rolled between the multiple sets of grooved wheels, and the inclined groove is formed on the rotating disk;

[0017] The rotating assembly also includes a meshing structure connecting the drive motor and the rotating disk.

[0018] As a further embodiment of the present invention: the center of the rotating disk is provided with a hollow part, and the meshing structure includes an internal gear ring disposed on the side wall of the hollow part and a gear connected to the output shaft of the drive motor, wherein the gear meshes with the internal gear ring.

[0019] As a further embodiment of the present invention: the support structure includes a second electric telescopic rod fixedly installed on the connecting plate, a connecting ring is connected to the actuating end of the second electric telescopic rod, a plurality of connecting plates are equidistantly arranged on the connecting ring, and a hysteresis groove is provided on the connecting plate along the radial direction of the guide plate, and the hysteresis shaft provided at the end of the deflector away from its rotation center can slide in the hysteresis groove.

[0020] When the connecting ring moves toward the guide plate, the deflector is able to rotate relative to the extension arm.

[0021] As a further aspect of the present invention, the length of the hysteresis groove is greater than the length of the slide groove.

[0022] As a further aspect of the present invention, it also includes:

[0023] A drive unit, on which two sets of electric telescopic arms are symmetrically mounted;

[0024] The connector is rotatably connected to the end of the electric telescopic arm away from the drive device, and the lower end of the connector is connected to the intermediate plate.

[0025] As a further embodiment of the present invention: the electric telescopic arm includes a connecting arm fixedly connected to the output shaft of the drive device, and a telescopic arm connected to the connector is slidably sleeved inside the connecting arm. The telescopic arm and the connecting arm are connected by a first electric telescopic rod.

[0026] The application of the high-adaptability sealing ring installation equipment described above in the assembly of solenoid valves.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] By using the deflector and support structure, it is ensured that the deflector can follow the movement of the extension arm when the diameter of the formed ring structure changes. This allows the sealing ring to actively slide off after being fitted. Secondly, since the deflector relies on its own elasticity to actively slide off, the sealing ring is under uniform force during the sliding process. Compared with the existing technology that uses a pusher to push the sealing ring, the sealing ring will not experience uneven force and stress concentration due to the push force from one side. This ensures the structural integrity of the sealing ring during the fitting of the sealing ring onto the solenoid valve interface and improves the sealing effect of the sealing ring in the later stage.

[0029] With the addition of extension arms and retraction / expansion components, during the synchronous operation of multiple extension arms, firstly, it can meet different processing requirements by changing the direct direction, facilitating the delivery of the sealing ring to the outside of the solenoid valve interface. Secondly, during the loading of the sealing ring into the extension arms, the multiple extension arms can be kept in a near-annular structure with the smallest diameter before being opened after the sealing ring is fitted onto the extension arms. This makes the installation of the sealing ring more convenient, avoids the need to pre-open the sealing ring and prevents it from twisting, and improves the sealing effect after installation.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0043] Please see Figures 1-10 In this embodiment of the invention, the high-adaptability sealing ring installation device includes: an intermediate plate 6, a connecting plate 7, a guide plate 8, an extension arm 16, a retractable assembly, a deflector 17, and a support structure.

[0044] The intermediate plate 6, connecting plate 7 and guide plate 8 are arranged in parallel.

[0045] The extension arm 16 is provided in multiple sets and can move along the radial direction of the guide plate 8.

[0046] The retractable assembly is disposed between the connecting plate 7 and the guide plate 8, and the retractable assembly can drive the extension arm 16 to move along the radial direction of the guide plate 8.

[0047] The retracting and expanding assembly includes multiple sets of sliding grooves 801 arranged circumferentially and equidistantly on the guide plate 8. The sliding grooves 801 face the radial direction of the guide plate 8, and a slider 15 is slidably installed in the sliding grooves 801. One side of the slider 15 is fixedly connected to the extension arm 16, and a convex shaft 14 is rotatably installed on the other side.

[0048] The expansion and contraction assembly also includes a drive motor 12 fixedly mounted on the intermediate plate 6. The output shaft of the drive motor 12 is connected to a rotating assembly. The rotating assembly is provided with multiple sets of inclined grooves 1001 that are tactilely connected to the convex shaft 14. Specifically, the inclined grooves 1001 move towards the center of the guide plate 8 along their length direction. When the inclined grooves 1001 make circular motion, they can drive the convex shaft 14 to slide along the length direction of the inclined grooves 1001.

[0049] In this embodiment, when the drive motor 12 is working, the rotating assembly connected to its output shaft can rotate, causing the inclined groove 1001 connected to the rotating assembly to perform circumferential motion. Since the inclined groove 1001 moves towards the center of the guide plate 8 along its length direction, it can cooperate with the convex shaft 14 during the forward and reverse rotation of the inclined groove 1001, thereby driving the slider 15 to move along the length direction of the groove 801. At this time, the multiple sets of extension arms 16 arranged circumferentially at equal intervals will also move closer or further away from the center of the guide plate 8, so that the multiple sets of extension arms 16 can form a ring-like structure with different diameters.

[0050] Based on the above configuration, during the synchronous operation of multiple extension arms 16, firstly, it can meet different processing requirements by changing the diameter of the ring-like structure formed by the extension arms 16 to support the ring to a diameter larger than that of the solenoid valve interface, thus facilitating the delivery of the ring to the outside of the solenoid valve interface. Secondly, during the loading of the ring into the extension arms 16, the multiple extension arms 16 can be kept in the state of the smallest diameter ring-like structure first, and then the ring can be opened after it is fitted onto the extension arms 16, making the installation of the ring more convenient and avoiding the need to pre-open the ring, which would cause the ring to twist and improve the sealing effect after installation.

[0051] Please see Figure 6 , Figure 9 The rotating assembly includes multiple sets of grooved wheels 9 arranged circumferentially at equal intervals on the guide plate 8, and a rotating disk 10 is rolled between the multiple sets of grooved wheels 9. The inclined groove 1001 is formed on the rotating disk 10.

[0052] The rotating assembly also includes a meshing structure connecting the drive motor 12 and the rotating disk 10. The rotating disk 10 has a hollowed-out portion in the middle. The meshing structure includes an internal gear ring 11 disposed on the side wall of the hollowed-out portion and a gear 13 connected to the output shaft of the drive motor 12. The gear 13 meshes with the internal gear ring 11.

[0053] During the operation of the drive motor 12, its output shaft can drive the gear 13 to rotate. The gear 13 is meshed with the internal gear ring 11, which allows the rotating disk 10 to rotate when the gear 13 rotates. The rotating disk 10 is connected to the guide plate 8 through multiple sets of grooved wheels 9. This arrangement ensures the coaxiality between the rotating disk 10 and the guide plate 8 during rotation, so that the multiple sets of inclined grooves 1001 can accurately cooperate with the cam shaft 14 and drive the multiple sets of cam shafts 14 to produce a consistent displacement when the inclined groove 1001 rotates at a predetermined angle, thereby ensuring the stability of the ring-like structure formed by the multiple sets of extension arms 16.

[0054] Furthermore, in this embodiment, during the installation of the sealing ring to the solenoid valve interface, it is necessary to keep the diameter of the sealing ring constantly expanded. Therefore, the aforementioned drive motor 12 is a motor with a self-locking output shaft. The accuracy of the expanded sealing ring size is related to the stability of the output shaft rotation angle of the drive motor 12. For existing drive motors 12, the output shaft rotation angle error is approximately 3% to 5%. If the output shaft of the drive motor 12 is directly connected to the rotating disk 10, the rotation angle of the rotating disk 10 will have a corresponding error, resulting in an error in the expanded size of the convex shaft 14. The possible consequences of this error include:

[0055] The sealing ring was not stretched to the correct size, making it impossible to fit properly onto the solenoid valve interface.

[0056] If the sealing ring is stretched to an excessive size, it can cause damage to the sealing ring structure or even breakage.

[0057] In this embodiment, by using a gear 13 and an internal gear ring 11 with a large difference in diameter (the diameter of the gear 13 is smaller than the diameter of the internal gear ring 13), the above-mentioned error can be reduced by a predetermined proportion, thereby improving the accuracy of the dimensions when the sealing ring is opened.

[0058] Please see Figures 3-8 , Figure 10 The deflector 17 is embedded in the extension arm 16. The deflector 17 is rotatably connected to the end of the extension arm 16 away from the guide plate 8. Specifically, the end of the deflector 17 away from its rotation center is abutted and adapted to the extension arm 16. When the two are abutted and adapted, the deflector 17 can be partially parallel to the extension arm 16, so that when the sealing ring is sleeved on the extension arm 16, the sealing ring is subjected to balanced force and will not slip off, thereby improving the stability of the sealing ring on the deflector 17 and the extension arm 16 in the initial state.

[0059] The support structure is connected to the deflector 17, and the support structure can drive the deflector 17 to rotate relative to the extension arm 16 so that the sealing ring sleeved on the extension arm 16 is disengaged.

[0060] The support structure includes a second electric telescopic rod 21 fixedly installed on the connecting plate 7. A connecting ring 20 is connected to the actuating end of the second electric telescopic rod 21. Multiple sets of connecting plates 19 are equidistantly arranged on the connecting ring 20. A hysteresis groove 1901 is provided on the connecting plate 19 along the radial direction of the guide plate 8. A hysteresis shaft 18 located at the end of the deflector 17 away from its rotation center can slide in the hysteresis groove 1901. The length of the hysteresis groove 1901 is greater than the length of the slide groove 801, so that when the diameter of the ring-like structure formed by the extension arm 16 is at its maximum, the hysteresis shaft 18 on the deflector 17 does not move to the end of the hysteresis groove 1901. This allows the hysteresis shaft 18 to still slide in the hysteresis groove 1901 when the connecting plate 19 moves toward the deflector 17, thereby driving the deflector 17 to deflect.

[0061] It should be noted that, for reference Figure 8The axis of rotation of the deflector 17 and the center line of the hysteresis shaft 18 are inclined upward. This setting can ensure that when the hysteresis groove 1901 moves, the hysteresis shaft 18 can move upward along the length direction of the hysteresis groove 1901, so as to lift the end of the deflector 17 away from its rotation center upward, thereby driving the deflector 17 to deflect.

[0062] When the connecting ring 20 moves toward the guide plate 8, the deflector 17 is able to rotate relative to the extension arm 16.

[0063] In the initial state, the actuating end of the second electric telescopic rod 21 is in the retracted state. At this time, the connecting ring 20 and the connecting plate 19 are in the predetermined position. With the cooperation of the hysteresis groove 1901 and the hysteresis shaft 18, the deflecting member 17 can be locked, ensuring the parallel stability between the deflecting member 17 and the extension arm 16, and ensuring the stability when the sealing ring is put on the deflecting member 17 and the extension arm 16 in the initial state.

[0064] When the rotating disk 10 makes a circular motion and uses the cooperation of the inclined groove 1001 and the convex shaft 14 to drive the extension arm 16 to move along the length direction of the slide groove 801, since the hysteresis groove 1901 and the slide groove 801 are both set along the radial direction of the guide plate 8, the hysteresis shaft 18 can slide in the hysteresis groove 1901. During this process, the deflector 17 follows the movement of the extension arm 16. At the same time, the deflector 17 is still in a locked state. That is, when the diameter of the ring-like structure formed by the extension arm 16 changes, it can drive the deflector 17 to move synchronously and keep the deflector 17 in a locked state.

[0065] When the end of the extension arm 16 moves to the predetermined position, the actuating end of the second electric telescopic rod 21 will move toward the guide plate 8. At this time, the connecting ring 20 and the connecting plate 19 will move toward the deflecting member 17. During this process, the hysteresis shaft 18 can cooperate with the hysteresis groove 1901 to deflect the deflecting member 17 and form a frustum structure with multiple sets of deflecting members 17. At this time, the sealing ring sleeved on the deflecting member 17 and the extension arm 16 can actively move toward the rotating shaft of the deflecting member 17 and be sleeved at the solenoid valve interface when separated from the deflecting member 17 to realize the installation of the sealing ring.

[0066] With the above settings, firstly, it can be ensured that when the diameter of the formed ring-like structure changes, the deflector 17 can move with the extension arm 16. Thus, after the sealing ring is fitted, the deflector 17 can actively slide off the sealing ring through deflection. Secondly, since the sealing ring actively slides off by its own elasticity, the sealing ring is in a state of uniform force during the sliding process. Compared with the method of pushing the sealing ring with a pusher in the prior art, the sealing ring will not be subjected to uneven force and stress concentration due to the push force on one side. This ensures the structural integrity of the sealing ring during the process of fitting the sealing ring onto the solenoid valve interface and improves the sealing effect of the sealing ring in the later stage.

[0067] It should also be noted that the device is particularly suitable for installing sealing rings with a circular cross-section. After the deflector 17 is deflected, the sealing ring with a circular cross-section can generate a certain rolling motion on the deflector 17, which can further reduce the probability of structural damage during the movement of the sealing ring.

[0068] Please see Figures 1-3 The high-adaptability sealing ring installation device further includes: a drive device 1 and a connector 5.

[0069] Two sets of electric telescopic arms are symmetrically installed on the drive device 1. Each electric telescopic arm includes a connecting arm 2 that is fixedly connected to the output shaft of the drive device 1. A telescopic arm 3 that connects to the connector 5 is slidably sleeved inside the connecting arm 2. The telescopic arm 3 and the connecting arm 2 are connected by a first electric telescopic rod 4.

[0070] In this embodiment, the drive device 1 uses an electric cylinder, whose output shaft has two important motion functions. On the one hand, it can realize rotation, thereby driving the connected arm 2 to perform circular motion. During the circular motion of the connected arm 2, the deflector 17 and the extension arm 16 located on both sides of the drive device 1 will change positions accordingly. On the other hand, the output shaft also has a lifting function, which can drive the connected arm 2 to perform lifting motion. This allows the entire device to flexibly adjust its working position during actual operation to adapt to different operational needs.

[0071] In actual sealing ring installation operations, the advantages of this structure are demonstrated. When one set of deflecting components 17 and extension arms 16 are performing sealing ring installation operations toward the solenoid valve interface, the other set of deflecting components 17 and extension arms 16 performs the action of loading the sealing ring. In this way, the two sets of deflecting components 17 and extension arms 16 can alternately perform the loading and installation of the sealing ring, which greatly improves the installation efficiency and makes the entire sealing ring production and installation process smoother and more efficient.

[0072] Before the drive device 1 drives the connecting arm 2 to rotate, the first electric telescopic rod 4 will first play its role, which can drive the telescopic arm 3 to retract into the connecting arm 2. The purpose of this is to make the rotation arm length of the two shorter when the drive device 1 drives the connecting arm 2 and the telescopic arm 3 to rotate. Since the rotation arm is shortened, the power required for rotation is reduced accordingly. This not only reduces the load on the drive device 1, but also improves the operating efficiency of the entire system, reduces energy consumption, extends the service life of the equipment, and also reduces the maintenance cost of the equipment.

[0073] Furthermore, considering the need to install different types of sealing rings in actual production, this device also has strong adaptability. By changing the length of the electric telescopic arm, it can accurately grasp specific types of sealing rings. This design allows the device to flexibly adapt to different production needs during actual operation. Regardless of the type of sealing ring, it can quickly and accurately complete the grasping and installation actions, greatly improving production efficiency and product quality stability. This high adaptability not only reduces the time wasted due to equipment replacement and debugging, but also enhances the flexibility of the entire production system, enabling it to better cope with market changes and diversified product demands.

[0074] The connector 5 is rotatably connected to the end of the electric telescopic arm away from the drive device 1, and the lower end of the connector 5 is connected to the intermediate plate 6.

[0075] In this embodiment, the angle between the connector 5 and the telescopic arm 3 is adjustable, and the adjustment methods are flexible and diverse, covering various means such as motor control and manual operation. For example, when using manual adjustment, different angles can be positioned by the cooperation of the pin and the slot, which is simple and reliable. This design gives the connector 5 and the telescopic arm 3 a wide range of angle changes. In practical applications, after the sealing ring is fitted on the extension arm 16 and the deflector 17, the orientation of the sealing ring's axis can be changed by adjusting the angle, thereby accurately matching the installation requirements of sealing rings of different models of solenoid valves.

[0076] Specifically, this technological advantage is particularly prominent when facing special working conditions. In many practical applications, the upper interface of the solenoid valve is not in a horizontal or vertical position, but at a certain angle to the valve body. This special structural layout often presents many challenges for traditional sealing ring installation equipment, making it difficult to complete the installation task efficiently and accurately. However, this device perfectly solves this problem with its unique design of adjustable angle between the connector 5 and the telescopic arm 3. No matter how the angle between the solenoid valve interface and the body changes, this device can flexibly adjust the orientation of the sealing ring's axis to ensure that the sealing ring can be accurately installed in place and achieve the sealing function.

[0077] This flexible angle adjustment capability greatly enhances the versatility and adaptability of the device. On the one hand, it enables the device to be widely used in the installation of solenoid valve sealing rings of various models and structures, meeting diverse industrial production needs. On the other hand, in actual operation, operators can quickly and accurately adjust to the required angle according to specific working conditions without replacing equipment or performing complex debugging, greatly improving production efficiency. In addition, this design also enhances the stability and reliability of the device. Because it can accurately match the angle of the solenoid valve interface, it avoids sealing problems caused by angle deviation, thereby ensuring the long-term stable operation of the equipment and reducing equipment failures and maintenance costs caused by seal failure.
