Description

Technical Field

[0001] The present invention relates to the technical field of air springs, and in particular to a bladder-skin assembly method and system. Background Art

[0002] Air springs, which utilize compressed air in a sealed container to achieve elasticity through the compressibility of the gas, are now becoming increasingly common in automotive suspension systems. To stabilize the relative position of the outer casing and the bladder, a large-diameter retaining ring is placed within the smaller bladder. This retaining ring acts as an inner support ring, securing the outer casing and ensuring a stable connection, thus ensuring the overall performance of the air spring.

[0003] During the assembly process of the air spring, a retaining ring needs to be installed in the soft bag sleeve to fix the soft bag sleeve. However, due to the difference in elastic coefficients of soft bag sleeves in different batches, the expansion degree of each soft bag sleeve under the same expansion force is different. When the retaining ring is installed in a way that causes the soft bag sleeve to expand and deform, it is easy to cause the retaining ring to have an inconsistent distance from one end of the soft bag sleeve, which brings inconvenience to the subsequent assembly of the air spring.

[0042] To solve the problem of inconsistent distances between the buckle ring and one end of the soft capsule sleeve in different batches of soft capsule sleeves, the present invention has the following advantages:

[0043] By supplying air into the soft-sleeve sleeve by the air supply assembly, the soft-sleeve sleeve expands radially, providing an initial expansion foundation for the installation of the retaining ring. Because soft-sleeve sleeves from different batches have different elastic coefficients, the second airflow parameter of the air supply assembly is adjusted according to the driving force F1, thereby adjusting the expansion degree of the soft-sleeve sleeve, making the deformation of soft-sleeve sleeves with different elastic coefficients tend to be consistent, and thus making their rebound amounts close. At the same time, after driving the pressing unit to move the retaining ring to the installation position, the pressing unit and the guide unit are driven away from the soft-sleeve sleeve and the air supply assembly stops supplying air, causing the soft-sleeve sleeve to gradually contract and embrace the retaining ring. Ultimately, the position difference of the retaining ring relative to one end of the soft-sleeve sleeve after the retaining ring is pressed into place for soft-sleeve sleeves with different elastic coefficients can be reduced, thus solving the problem of inconsistent retaining ring distances due to different elastic coefficients of soft-sleeve sleeves from different batches, which makes air spring assembly inconvenient.

[0057] During the assembly of the air spring cover assembly 40, a retaining ring 42 needs to be installed inside the air spring cover 41. This retaining ring 42 is used to secure the air spring cover 41 to the air spring. Currently, the retaining ring 42 is installed by inflating the air spring cover 41. However, due to differences in the elastic modulus of air spring covers 41 from batch to batch, the distance between the retaining ring 42 and one end of the air spring cover 41 can be inconsistent during installation. This inconsistency in distance creates inconvenience during subsequent assembly of the air spring.

[0058] Example 1:

[0059] In order to solve the above problems, this embodiment discloses a method for assembling a bladder skin assembly 40 .

[0060] In this embodiment, if Figure 1As shown, the method for assembling the capsule assembly 40 includes steps S10 to S50:

[0061] Step S10: Based on the fact that one end of the soft capsule sleeve 41 is clamped and sealed and the retaining ring 42 is in contact with the pressing unit 13, the guide unit 12 and the pressing unit 13 are driven to move toward the soft capsule sleeve 41. This step provides the initial movement basis for the retaining ring 42 to enter the soft capsule sleeve 41. The synchronous movement of the guide unit 12 and the pressing unit 13 ensures that the retaining ring 42 is aligned with the entrance of the soft capsule sleeve 41. Figure 2 As shown, the bladder skin assembly 40 assembly system includes a pressing assembly 10, a supporting assembly 20, and an air supply assembly 50. The pressing assembly 10 includes a guide unit 12 and a pressing unit 13. One end of the guiding unit 12 is a guiding end, which is in the shape of a cone, and the other end is slidably connected to the inner circumferential wall of the pressing unit 13. The end of the pressing unit 13 close to the guiding unit 12 can position the retaining ring 42 by magnetic adsorption or clamping. The supporting assembly 20 is coaxially spaced from the guiding unit 12. The supporting assembly 20 is used to position and clamp one end of the soft bladder sleeve 41. The air supply assembly 50 can supply airflow into the soft bladder sleeve 41.

[0062] In step S20, with the guide unit 12 in contact with the soft bag sleeve 41, the air supply assembly 50 provides airflow into the soft bag sleeve 41, causing the soft bag sleeve 41 to expand radially. At this point, the air supply assembly 50 supplies airflow at the initial air supply parameters, expanding the soft bag sleeve 41 through the airflow. This prevents the soft bag sleeve 41 from being scratched and damage, while also expanding the internal space and facilitating the entry of the retaining ring 42 into the soft bag sleeve 41.

[0063] In step S30, based on the air supply assembly 50 providing airflow into the soft-sleeve sleeve 41, causing the soft-sleeve sleeve 41 to expand radially and the downward-pressing unit 13 to abut against the soft-sleeve sleeve 41, a driving force F1 is obtained that drives the guide unit 12 and the downward-pressing unit 13 to move. The driving force F1 reflects the force between the downward-pressing unit 13 and the soft-sleeve sleeve 41, and thus reflects the elastic properties of the soft-sleeve sleeve 41. During the process of the pressing unit 13 pressing the retaining ring 42 to the installation position of the soft bag sleeve 41, its driving force F1 increases due to the increase in the force between the pressing unit 13 and the inner wall of the soft bag sleeve 41, and has a corresponding change curve. When the pressing unit 13 extends into the soft bag sleeve 41 to a certain area, the driving force F1 in the area has a corresponding reference range. In order to make the real-time driving force F1 within the reference range, the air flow parameters of the air supply component 50 are adjusted. For example, when the driving force F1 is greater than the reference threshold, the flow rate or pressure of the air flow supplied by the air supply component 50 is increased; when the driving force F1 is less than the reference threshold, the flow rate or pressure of the air flow supplied by the air supply component 50 is reduced. This can effectively maintain the expansion degree of the soft bag sleeves 41 with different elastic coefficients to be consistent, and reduce the position difference of the retaining ring 42 compared to one end of the soft bag sleeve 41 after the pressing is completed.

[0064] In step S40, based on the acquired driving force F1, the air supply assembly 50 provides airflow into the soft bladder sleeve 41 at a second airflow parameter. The second airflow parameter is determined based on the driving force F1. By adjusting the airflow parameter based on the driving force F1, the expansion degrees of soft bladder sleeves 41 with different elastic coefficients can be made consistent, providing a stable environment for the installation of the retaining ring 42.

[0065] In step S50, after pressing down unit 13 has been driven to position retaining ring 42, pressing down unit 13 and guiding unit 12 are driven to move away from bladder cover 41, and air supply assembly 50 reduces and eventually stops the airflow. After securing retaining ring 42, pressing down unit 13 and guiding unit 12 are removed, and air supply is gradually stopped, causing bladder cover 41 to retract and secure retaining ring 42, thus reducing the positional discrepancy.

[0066] Furthermore, based on the fact that one end of the soft bag sleeve 41 is clamped and sealed and the retaining ring 42 is in contact with the pressing unit 13, the guiding unit 12 and the pressing unit 13 are driven to move toward the soft bag sleeve 41, that is, step S10. Step S10 includes step S11 and step S12:

[0067] Step S11: Based on the clamping and sealing of one end of the soft bag sleeve 41 and the contact between the pressing ring 42 and the pressing unit 13, the second guide cone 123 is unfolded. Figure 3As shown, the guide unit 12 includes a first guide cone 121, a second guide cone 123, and a second drive portion 122. One end of the first guide cone 121 passes through the pressing unit 13 and is detachably connected to the pressing seat unit 11, and the other end extends in a direction away from the pressing seat unit 11. The inner peripheral wall of the pressing unit 13 is slidably connected to the first guide cone 121. The second guide cone 123 is located between the first guide cone 121 and the pressing unit 13. The second guide cone 123 is sleeved on the first guide cone 121. After the second guide cone 123 is unfolded, the minimum diameter of the outer contour is equal to the maximum outer diameter of the first guide cone 121. After the second guide cone 123 is unfolded, the maximum diameter of the outer contour is equal to the outer diameter of the retaining ring 42. The outer diameter of the end of the first guide cone 121 away from the pressing unit 13 gradually decreases in a direction away from the pressing unit 13. The outer diameter of the end of the second guide cone 123 away from the pressing unit 13 gradually decreases in a direction close to the first guide cone 121. Thus, it can play a guiding role. In addition to being able to move axially, the second guide cone 123 can also be expanded or retracted radially under the drive of the second drive unit 122. Since the pressing unit 13 is sleeved on the first guide cone 121, there is a large difference in outer diameter between the first guide cone 121 and the pressing unit 13. By expanding the second guide cone 123 and matching its size with the first guide cone 121, it is possible to prevent the inner wall of the soft bladder sleeve 41 and the side of the retaining ring 42 near the first guide cone 121 from scratching due to the stepped transition, thereby protecting the soft bladder sleeve 41. At the same time, after the second guide cone 123 is expanded, it can clamp the retaining ring 42 with the pressing unit 13, ensuring that the retaining ring 42 is not affected by airflow and falls off when it is not pressed into place, thereby improving the smoothness of the retaining ring 42 press-fitting the soft bladder sleeve 41.

[0068] In step S12, the second guide cone 123 is deployed to drive the guide unit 12 and the pressing unit 13 to move toward the soft bag sleeve 41. After the second guide cone 123 is deployed, it clamps the retaining ring 42 with the pressing unit 13 to ensure that the retaining ring 42 does not fall off during the pressing process, thereby improving the press-fitting smoothness.

[0069] Furthermore, based on the contact between the guide unit 12 and the soft bag sleeve 41, the air supply assembly 50 provides airflow into the soft bag sleeve 41, causing the soft bag sleeve 41 to expand radially. This is step S20. Step S20 includes: based on the contact between the guide unit 12 and the soft bag sleeve 41, the air supply assembly 50 provides airflow into the soft bag sleeve 41 with a first airflow parameter, causing the soft bag sleeve 41 to expand radially. The flow rate of the first airflow parameter is greater than the flow rate of the second airflow parameter. The guidance of the guide unit 12 and the impact of the high flow rate of the first airflow parameter cause the cross-sectional shape of the soft bag sleeve 41 to approach a circle, reducing the risk of curling of the soft bag sleeve 41 when the guide unit 12 contacts the soft bag sleeve 41. In other embodiments, the pressure of the first airflow parameter is lower than the pressure of the second airflow parameter. This ensures that the soft bag sleeve 41 is circular when expanded, using the high flow rate and low pressure of the first airflow parameter. After the soft bag sleeve 41 is fully blocked, the second airflow parameter with low flow rate and high pressure is switched to slowly expand the soft bag sleeve 41, ensuring sufficient and uniform expansion.

[0070] Furthermore, based on the air supply component 50 providing air flow into the soft bag sleeve 41 to cause the soft bag sleeve 41 to expand in its radial direction and the pressing unit 13 to abut against the soft bag sleeve 41, a driving force F1 for driving the guide unit 12 and the pressing unit 13 to move is obtained, that is, step S30. Step S30 includes step S31 and step S32:

[0071] In step S31, the air supply assembly 50 provides airflow into the soft bag sheath 41 to expand the soft bag sheath 41 radially, and the pressing unit 13 is continuously driven to move toward the soft bag sheath 41. Continuously moving the pressing unit 13 ensures full contact with the expanded soft bag sheath 41, laying the foundation for obtaining accurate driving force.

[0072] In step S32, based on the contact area between the pressing unit 13 and the soft bladder sleeve 41 reaching the set area range, the driving force F1 that drives the guide unit 12 and the pressing unit 13 is obtained. At this point, the growth curve of the driving force F1 tends to be stable, and the obtained driving force F1 is more accurate, facilitating subsequent adjustment of the air supply parameters based on this force.

[0073] Furthermore, based on driving the pressing unit 13 to move the buckling ring 42 to the installation position, the pressing unit 13 and the guide unit 12 are driven to move in a direction away from the soft bag sleeve 41, and the air supply component 50 reduces the air flow supply until the air flow supply is stopped, that is, step S50. Step S50 includes steps S51 to S54:

[0074] In step S51, the air supply assembly 50 provides airflow with second airflow parameters into the soft capsule sleeve 41, causing the soft capsule sleeve 41 to expand radially. This drives the guide unit 12 and the downward pressure unit 13 to a retracted cone position. This position prepares the guide unit 12 and the downward pressure unit 13 for subsequent retraction of the second guide cone 123, ensuring a consistent operational flow.

[0075] In step S52, the second guide cone 123 is retracted by driving the guide unit 12 and the pressing unit 13 to the retracted position. The maximum diameter of the retracted outer contour of the second guide cone 123 is smaller than the inner diameter of the retaining ring 42. Retracting the second guide cone 123 and controlling its size prevents obstruction to the movement of the retaining ring 42 and provides space for the retaining ring 42 to reach the set position.

[0076] In step S53, the pressing unit 13 is driven to move the retaining ring 42 to the set position based on the retraction of the second guide cone 123. Driving the pressing unit 13 without the obstruction of the second guide cone 123 ensures that the retaining ring 42 moves accurately to the set position and avoids skew due to structural interference.

[0077] In step S54, based on driving the pressing unit 13 to position the retaining ring 42, the pressing unit 13 and the guide unit 12 are driven away from the bladder sleeve 41, and the air supply assembly 50 reduces the airflow until it stops. Once the retaining ring 42 is in place, the pressing unit 13 and the guide unit 12 are removed, and the airflow is gradually reduced, causing the bladder sleeve 41 to gradually retract and embrace the retaining ring 42, securing its position. This prevents the retaining ring 42 from being distorted by friction caused by the removal of the pressing unit 13 and the guide unit 12. Furthermore, this prevents rapid contraction of the bladder sleeve 41 and reduces the mutual forces between the bladder sleeve 41 and the pressing unit 13 and the guide unit 12, thereby reducing friction between the pressing unit 13 and the guide unit 12 and the inner circumferential wall of the bladder sleeve 41, improving removal efficiency and preventing excessive interference of the pressing unit 13 with the bladder sleeve 41. This ensures a stable position of the retaining ring 42 and a smooth press-fitting process.

[0078] Furthermore, based on driving the pressing unit 13 to move the buckling ring 42 to the installation position, the pressing unit 13 and the guiding unit 12 are driven to move in a direction away from the soft bag sleeve 41 and the air supply assembly 50 reduces the air flow supply until the air flow supply is stopped, that is, step S54. Step S54 includes step S541 and step S542:

[0079] In step S541, the pressing ring 42 is moved to the installation position by driving the pressing unit 13, and the third limiting unit 23 is engaged with the pressing ring 42. The engagement of the third limiting unit 23 with the pressing ring 42 can further fix the position of the pressing ring 42 and prevent it from being displaced or tilted in subsequent operations. Figure 4 、 Figure 5 、 Figure 6As shown, the support assembly 20 includes a sealing unit 21, a second limiting unit 22, and a third limiting unit 23. The sealing unit 21 is used to seal the end of the soft bladder sleeve 41 away from the first guide cone 121. The second limiting unit 22 limits the expansion of the outer circumference of the lower half of the soft bladder sleeve 41. The end surface of the second limiting unit 22, which is adjacent to the pressing unit 13, is located adjacent to the set position of the retaining ring 42 within the soft bladder sleeve 41, preventing the retaining ring 42 from being pressed too far during installation. The third limiting unit 23 includes a rotating rod 231, a swing arm 232, a locking portion 233, and a fifth driving portion 234. One end of the rotating rod 231 is detachably connected to the end of the sealing unit 21 that is adjacent to the first guide cone 121. Multiple rotating rods 231 are spaced apart along the circumference of the sealing unit 21. One end of the swing arm 232 is detachably connected to the end of the rotating rod 231 that is away from the sealing unit 21, and the other end is connected to the locking portion 233. The engaging portion 233 may be a contoured groove or a clamping claw to facilitate positioning and securing the inner circumferential wall of the retaining ring 42. The fifth driving portion 234 drives the rotating rod 231 to rotate, thereby driving the swing arm 232 to move toward or away from the adjacent rotating rod 231. The axis of the swing arm 232 may be tangent to the circumference of the rotating rod 231 or the central column 211.

[0080] In step S542, based on the engagement between the third limiting unit 23 and the retaining ring 42, the pressing unit 13 and the guiding unit 12 are driven to move away from the soft bladder sleeve 41, and the air supply assembly 50 reduces the airflow supply until it stops. After the retaining ring 42 is secured, the pressing unit 13 and the guiding unit 12 are removed and the airflow is reduced. This prevents interference with the retaining ring 42 during the removal process, allowing the soft bladder sleeve 41 to gradually contract and firmly embrace the retaining ring 42.

[0081] Furthermore, based on the engagement of the third limiting unit 23 with the retaining ring 42, the pressing unit 13 and the guiding unit 12 are driven to move in a direction away from the soft bag sleeve 41, and the air supply assembly 50 reduces the air flow supply until the air flow supply is stopped, that is, step S542. Step S542 includes steps S5421 to S5423:

[0082] In step S5421, based on the engagement between the third limiting unit 23 and the buckling ring 42, the pressing unit 13 and the guiding unit 12 are driven to move away from the soft bag sleeve 41. The pressing unit 13 and the guiding unit 12 are driven to withdraw, leaving space for the soft bag sleeve 41 to shrink and fix the buckling ring 42.

[0083] In step S5422, the air supply assembly 50 reduces the air flow supply until the air flow supply is stopped after the downward pressure unit 13 and the guide unit 12 are driven to move away from the soft bag cover 41 and reach the retracted distance range. The air supply assembly 50 stops the air flow supply before the downward pressure unit 13 is separated from the soft bag cover 41. During the withdrawal of the pressing unit 13 and the guiding unit 12, there is friction between the pressing unit 13 and the soft bag sleeve 41, so that the pressing unit 13 will pull the soft bag sleeve 41 toward the withdrawal direction. In order to reduce the force of the soft bag sleeve 41 holding the pressing unit 13, the supply air flow parameters of the air supply component 50 remain unchanged at this time, so that the soft bag sleeve 41 maintains a relatively constant expansion degree, avoiding excessive friction before the pressing unit 13 and the guiding unit 12 reach the contraction distance range, reducing the deformation of the soft bag sleeve 41 caused by pulling when the pressing unit 13 and the guiding unit 12 are withdrawn, and reducing the air supply when the pressing unit 13 and the guiding unit 12 are withdrawn to the contraction distance range, thereby avoiding excessive deformation of the soft bag sleeve 41 caused by pulling, which may cause the retaining ring 42 to be skewed.

[0084] In step S5423, based on the distance that the pressing unit 13 and the guiding unit 12 are driven to move away from the soft bag sleeve 41 and reach the retracted distance range, the pressing unit 13 and the guiding unit 12 are further driven to move away from the soft bag sleeve 41 until the guiding unit 12 is spaced apart from the soft bag sleeve 41. To prevent the distance between the position where the soft bag sleeve 41 is pulled and deformed and the inner wall of the soft bag sleeve 41 near the side of the retaining ring 42 away from the pressing unit 13 from being too small, the pressing unit 13 and the guiding unit 12 are moved to the retracted distance range and then the air flow supply is reduced and the withdrawal is continued, so that the soft bag sleeve 41 gradually embraces the retaining ring 42. The area where the soft bag sleeve 41 is pulled and deformed is located on the side of the retaining ring 42 near the pressing unit 13. This reduces the effect of friction pulling the soft bag sleeve 41 on the soft bag sleeve 41 near the side of the retaining ring 42 away from the pressing unit 13 during withdrawal, reduces the deformation at this location, prevents the retaining ring 42 from skewing, and enhances the connection stability. The guiding unit 12 is completely separated from the soft bag sleeve 41 to avoid subsequent interference with the soft bag sleeve 41 and the buckling ring 42 .

[0085] Furthermore, based on the engagement of the third limiting unit 23 with the retaining ring 42, the pressing unit 13 and the guiding unit 12 are driven to move in a direction away from the soft bag sleeve 41, and the air supply assembly 50 reduces the air flow supply until the air flow supply is stopped, that is, step S542. Step S542 also includes step S5424:

[0086] In step S5424, the guide unit 12 is spaced apart from the soft bladder sleeve 41, and the third limiting unit 23 is spaced apart from the retaining ring 42. After the guide unit 12 is disengaged, the third limiting unit 23 is also disengaged. This prevents the retaining ring 42 from shifting due to loss of support and rebound of the soft bladder sleeve 41 when the guide unit 12 and the pressing unit 13 are completely disengaged from the soft bladder sleeve 41.
