Description

Technical Field

[0001] This invention relates to the field of vibration damping component assembly technology, and in particular to an air spring airbag and buckle assembly device. Background Technology

[0002] Air springs are vibration damping devices installed on railway vehicles to isolate vibrations between the bogie and the car body, thereby providing passengers with a comfortable riding experience.

[0003] An air spring is assembled from an air bladder and a retainer. The retainer is a closed ring-shaped component made of metal, which is highly rigid and not easily deformed. The air bladder is a flexible component made of rubber composite material. Its upper and lower mating parts are highly rigid and not easily deformed, while the remaining parts can deform significantly under large external forces. During assembly, the retainer needs to be fitted onto the upper mating part of the air bladder. Because the upper mating part of the air bladder is highly rigid, the retainer can only be fitted from the bottom up. Furthermore, due to the structural characteristics of the air spring, the air bladder itself is much larger than the retainer, and the retainer is a closed ring-shaped component. Therefore, external force is needed to compress the air bladder to deform it before it is inserted into the retainer until the retainer and the upper mating part of the air bladder are fully assembled.

[0004] Currently, air springs are assembled manually, requiring assemblers to squeeze the airbags forcefully, which is extremely physically demanding and difficult to assemble. Furthermore, the rigidity of airbags of different specifications varies. The smaller the airbag volume, the greater the rigidity and the more difficult it is to deform, making the assembly of air springs more difficult, and sometimes even impossible to complete manually.

[0043] According to the present invention, an air spring airbag and buckle assembly device is provided, which includes a first drive assembly and a second drive assembly.

[0044] In this embodiment, as Figure 1 and Figure 2 As shown, the air spring includes an annular air bladder 60 and a retaining ring 70, wherein the retaining ring 70 is formed as a closed annular structure, and a mounting portion 63 for assembling the retaining ring 70 is formed on the top of the outer side wall 61 of the air bladder 60.

[0045] In this embodiment, as Figures 3 to 7As shown, the first drive assembly is used to compress the airbag 60 to deform, and the second drive assembly is used to fit the buckle 70 onto the airbag 60 to assemble it into an air spring. Specifically, the first driving assembly includes a first driving member 11, an outward pushing assembly 12, and a compression assembly 13. The first driving member 11 is connected to the outward pushing assembly 12 and the compression assembly 13 respectively. The outward pushing assembly 12 abuts against the inner sidewall 62 of the airbag 60, and the compression assembly 13 abuts against the outer sidewall 61 of the airbag 60. That is, the airbag 60 is installed between the outward pushing assembly 12 and the compression assembly 13. The first driving member 11 can drive the outward pushing assembly 12 and the compression assembly 13 to move closer to or further away from each other. Thus, when the airbag 60 is compressed, the expansion of the inner diameter of the airbag 60 and the contraction of the outer diameter of the airbag 60 are realized simultaneously. Compared with the method of compressing only the outer diameter of the airbag, the simultaneous compression of the inner and outer diameters can ensure that the airbag 60 is vertically fixed and that the elastic airbag 60 is not squeezed out during the compression process (i.e., it will not separate from the outward pushing assembly 12 and / or the compression assembly 13). Furthermore, in this embodiment, the first driving component 11 drives the push component 12 and the compression component 13 to move closer or further away from each other to fix the airbag 60, so that the air spring airbag and buckle assembly device can fix and clamp airbags 60 of different sizes without replacing the first driving component.

[0046] It should be noted that the advantages of this application also include: the push assembly 12 and the compression assembly 13 can be controlled to move relative to each other or in opposite directions using only a single first drive component 11 to compress the airbag 60. This ingenious design achieves cost reduction and energy saving. Furthermore, it makes the structure of the first drive component more compact, thus making the air spring airbag and buckle assembly device of this application suitable for air springs with very small inner diameters of the airbag 60.

[0047] Furthermore, in this embodiment, the second driving component includes a second driving member 21 and a push-pull member 22; the buckle 70 is installed on the push-pull member 22, and the second driving member 21 is connected to the push-pull member 22 to drive the push-pull member 22 to move along the axial direction of the buckle 70, thereby driving the buckle 70 to be fitted onto the outer side wall 61 of the airbag 60 in a sleeve manner.

[0048] Specifically, such as Figures 3 to 7 As shown, the push-pull member 22 is formed as an annular structure surrounding the outside of the first drive assembly. The top of the push-pull member 22 has a recessed positioning portion 221 for mounting the retaining ring 70. The second drive member 21 is disposed below the push-pull member 22 and has a second drive end 211. The second drive end 211 is connected to the bottom of the push-pull member 22 and is used to drive the push-pull member 22 to lift or lower. The first drive assembly can compress and deform the airbag 60. The retaining ring 70 passes through the deformed airbag 60 from the bottom of the airbag 60 and is mounted on the mounting portion 63.

[0049] The assembly process of airbag 60 and buckle 70 is as follows:

[0050] S1. The first driving component 11 drives the outward pushing component 12 and the extrusion group to move closer to each other, so that the airbag 60 is extruded and deformed to ensure that the buckle 70 passes through.

[0051] S2. The buckle 70 is installed on the push-pull member 22. The second drive member 21 drives the push-pull member 22 to move towards the airbag 60, thereby driving the buckle 70 through the squeezed and deformed airbag 60 and conveying the buckle 70 to the mounting part 63.

[0052] S3. After the buckle 70 is assembled into the mounting part 63, the second driving member 21 drives the push-pull member 22 to move away from the airbag 60 to avoid interfering with the rebound of the airbag 60.

[0053] S4. The first driving component 11 drives the push assembly 12 and the compression assembly 13 to move away from each other. The deformed airbag 60 gradually rebounds and returns to its normal state when the body is not subjected to external force, thereby completing the assembly of the air spring airbag and the buckle.

[0054] In a preferred embodiment, such as Figures 3 to 7 As shown, the first driving assembly has multiple sets of push-out components 12 and compression components 13. The multiple sets of push-out components 12 and compression components 13 are synchronously driven by a first driving member 11. The multiple sets of push-out components 12 are arranged at intervals around the inner sidewall 62 of the airbag 60, and the multiple sets of compression components 13 are arranged at intervals around the outer sidewall 61 of the airbag 60. This allows the airbag 60 to be compressed evenly, ensuring that the airbag 60 can be compressed proportionally. This reduces the friction between the airbag 60 and the buckle 70 during assembly, protecting the surface of the airbag 60 while also reducing wear on the protective layer (such as paint, electroplating, anodizing) on ​​the surface of the buckle 70.

[0055] In one embodiment, multiple sets of push-out components 12 and multiple sets of compression components 13 are arranged alternately around the circumference of the airbag 60.

[0056] In another embodiment, each set of push-out components 12 and each set of compression components 13 are arranged radially correspondingly along the airbag 60.

[0057] It should be noted that, in this embodiment, both the first driving member 11 and the second driving member 21 can be electric push rods, pneumatic push rods or hydraulic push-pull cylinders, or other power sources that can achieve the above driving effect.

[0058] More specifically, in this embodiment, as Figures 3 to 7As shown, the first driving member 11 has a first driving end 111. For example, when the first driving member 11 is an electric push rod, the first driving end 111 is a push rod that can reciprocate and extend. The first driving end 111 can reciprocate along the axial direction of the airbag 60. The structure of the second driving end 211 can be the same as the structure of the first driving end 111.

[0059] In this embodiment, the first driving member 11 is disposed below the push assembly 12 and the squeeze assembly 13, and the first driving end 111 can move upward to extend or downward to retract; the second driving member 21 is disposed below the push-pull member 22.

[0060] In this embodiment, both the push-out assembly 12 and the compression assembly 13 are formed as linkage mechanisms, thereby ensuring that the push-out assembly 12 and the compression assembly 13 move flexibly and reliably to meet the requirements of the compressed airbag 60. Specifically, as shown in the figure... Figures 3 to 7 As shown, the push-out assembly 12 includes a push-out arm 121 and a first connector 122. The push-out arm 121 abuts against the inner wall 62 of the airbag 60. The first connector 122 is hinged to the push-out arm 121 and the first drive end 111 respectively. When the first drive end 111 extends, the first connector 122 rises synchronously, thereby driving the push-out arm 121 to retract inward. Conversely, when the first drive end 111 retracts, the first connector 122 moves downward synchronously and drives the push-out arm 121 to open outward.

[0061] More specifically, such as Figures 3 to 7 As shown, the compression assembly 13 includes a compression arm 131 and a second connector 132. The compression arm 131 abuts against the outer wall 61 of the airbag 60. The second connector 132 is hinged to the compression arm 131 and the first drive end 111 respectively. When the first drive end 111 extends, the second connector 132 rises synchronously, thereby pushing the compression arm 131 to open outward. Conversely, when the first drive end 111 retracts, the second connector 132 moves downward synchronously and drives the compression arm 131 to retract inward. This achieves that when the first drive end 111 extends, the compression arm 131 and the push arm 121 move away from each other, and when the first drive end 111 retracts, the compression arm 131 and the push arm 121 move closer to each other.

[0062] In this embodiment, as Figures 3 to 7As shown, the first driving end 111 is formed into a rod-shaped structure. The side wall of the first driving end 111 is provided with a first connecting part 1111 and a second connecting part 1112. The first connecting member 122 is hinged to the first connecting part 1111, and the second connecting member 132 is hinged to the second connecting part 1112. Along the length direction of the first driving end 111, the first connecting part 1111 and the second connecting part 1112 are spaced apart to ensure that under the driving action of the first driving member 11, the push assembly 12 and the compression assembly 13 move along the trajectory that can compress the airbag 60.

[0063] More specifically, in this embodiment, as Figures 3 to 7 As shown, the first connecting portion 1111 and the second connecting portion 1112 can be formed as a plate-like structure protruding along the circumferential sidewall of the first driving end 111, so that it can be connected to a plurality of first connecting members 122 or second connecting members 132.

[0064] In the embodiment, the first connecting part 1111 is disposed above the second connecting part 1112. However, the relative position and the distance between the first connecting part 1111 and the second connecting part 1112 can be adjusted according to the actual compression of the airbag 60, as long as it can ensure the compression of airbags 60 of different specifications.

[0065] In this embodiment, the deformation of the airbag 60 is to fit the buckle 70 onto the outer wall 61 of the airbag 60. Therefore, the movement range of the compression component 13 is preferably greater than that of the push component 12, resulting in a larger deformation of the outer wall 61 of the airbag 60. This ensures that the buckle 70 passes through smoothly. For this purpose, as follows... Figures 3 to 7 As shown, the first connecting member 122 is formed as a rod-shaped structure capable of extending and retracting along its length. The outward push arm 121 and the first driving end 111 are respectively disposed at both ends of the first connecting member 122 along its length. This allows the first connecting member 122 to passively extend or shorten with the reciprocating motion of the first driving end 111. Specifically, when the first driving end 111 extends, the length of the first connecting member 122 increases, thereby reducing the inward contraction of the outward push arm 121; when the first driving end 111 retracts, the length of the first connecting member 122 decreases, thereby reducing the outward opening of the outward push arm 121, giving the outward push arm 121 a certain degree of adaptive flexibility. Furthermore, because the outward push arm 121 has a certain degree of adaptive flexibility, this can further expand the size range of the airbag 60 that the first driving assembly can hold, thereby meeting the assembly requirements of more air springs of different specifications.

[0066] In this embodiment, the first connector 122 is formed as a telescopic sleeve structure (e.g., a telescopic connecting cylinder).

[0067] In a preferred embodiment, such as Figures 3 to 7As shown, both the push arm 121 and the squeeze arm 131 are formed into curved rod-like structures to conform to the airbag 60, thereby increasing the contact area between the push arm 121 and the squeeze arm 131 and the airbag 60 so as to apply force.

[0068] Furthermore, in this embodiment, the push arm 121 is formed with a snap-fit ​​portion 1211 protruding toward the airbag 60, which is used to snap the top of the airbag 60, thereby positioning the airbag 60 and ensuring that the airbag 60 will not separate from the push arm 121 and the compression arm 131 during the compression deformation process.

[0069] Furthermore, in this embodiment, as Figure 5 As shown, a protective element 30 is provided on the side of the compression arm 131 and the push arm 121 facing the airbag 60. The protective element 30 can abut against the airbag 60 to protect the airbag 60 and prevent the compression arm 131 or the push arm 121 from damaging the surface of the airbag 60 when compressing it. The protective element 30 is preferably made of nylon to provide a certain degree of wear resistance.

[0070] In this embodiment, as Figures 3 to 7 As shown, the air spring airbag and buckle assembly device also includes a housing 40. The first drive assembly and the second drive assembly are both disposed inside the housing 40. A support member 41 is disposed inside the housing 40. The push assembly 12 and the squeeze assembly 13 are respectively hinged to the support member 41. Specifically, the main bodies of the first drive member 11 and the second drive member 21 are both installed on the inner wall of the housing 40, such as the bottom wall. The support member 41 is formed as a plate structure and forms a certain distance with the bottom wall of the housing 40. The main body of the first drive member 11 is disposed between the support member 41 and the bottom wall of the housing 40. The support member 41 is provided with a through hole through its main body for the first drive end 111 to extend out. The ends of the push arm 121 and the squeeze arm 131 in the length direction are hinged to the support member 41, so that the push arm 121 and the squeeze arm 131 swing with the hinge point with the support member 41 as the center, thereby realizing that the push arm 121 and the squeeze arm 131 can open outward or retract inward.

[0071] Furthermore, in this embodiment, as Figures 3 to 7 As shown, the top of the housing 40 has an opening. The air spring 60 and the buckle 70 are inserted into or removed from the housing 40 through this opening. The air spring 60 and buckle assembly device also includes an end cap 50 on the top of the housing 40 to close at least part of the opening. During the assembly of the air spring 60 and buckle 70, the end cap 50 is closed; after the air spring 60 and buckle are assembled, or when it is necessary to place the air spring 60 and buckle 70 into the housing 40, the end cap 50 is opened.

[0072] In one alternative embodiment, the end cap 50 is configured to open and close in a horizontal direction.

[0073] It should be noted that when the buckle 70 needs to be placed, the end cover 50 should be opened and the second drive end 211 should be extended to the top. After the buckle 70 is placed in the positioning part 221, the second drive end 211 should be retracted to the bottom. At this time, the airbag 60 can be placed between the push assembly 12 and the compression assembly 13, and then the end cover 50 should be closed.

[0074] In this embodiment, the air spring airbag and buckle assembly device further includes a first drive component connected to it. The second drive component is connected to an electronic control module 80, which includes operation buttons or an operation panel located on the outer wall of the housing 40. The assembler can control the first drive component 11 and the second drive component 21 via the operation buttons or the operation panel to achieve automatic assembly of the airbag 60 and buckle 70 within the housing 40. Furthermore, the electronic control module 80 can be a control program module with automatic execution function, enabling one-button automatic execution of the entire set of actions of the drive component, thus completely simplifying manual operation.

[0075] Furthermore, the end cap 50 can also be connected to the electronic control module 80, thus automatically controlling the opening and closing of the end cap 50. After the air spring bladder and the buckle are assembled, the end cap 50 can be opened automatically for the assembly personnel to remove.

[0076] The air spring airbag and buckle assembly device according to the present invention has a simple and compact structure and low manufacturing cost. The airbag is deformed by the combined action of an outward pushing component and a compression component, and a second driving component drives a push-pull component to move along the axial direction of the buckle, so that the buckle is assembled on the outer side wall of the airbag. This automatically completes the assembly of the air spring airbag and buckle, ensuring assembly quality, significantly reducing the labor intensity of assembly personnel, and meeting the assembly requirements of air spring airbags and buckles of different specifications. By setting multiple sets of outward pushing and compression components, the airbag is uniformly compressed, ensuring that the airbag is compressed proportionally, thereby protecting the airbag surface while reducing wear on the protective layer of the buckle surface. Furthermore, the telescopic first connecting member allows for different opening and closing ranges of the compression arm and the outward pushing arm, resulting in a simple and compact structure.

[0077] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them.
