[0031] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0032] like Figures 1 to 4 As shown, this utility model embodiment provides a spring disassembly device, including:

[0033] The card plate 100 is provided with a claw 102, which is used to engage the seat 104 of the air spring.

[0034] The first support column 106 is arranged on one side of the snap-fit ​​plate 100 along the circumference of the snap-fit ​​plate 100. The first support column 106 is provided with a positioning block 108, which is used to clamp and support the cover 110 of the air spring.

[0035] The second support column 112 is arranged along the circumference of the retaining plate 100 on one side of the retaining plate 100 and is offset from the first support column 106. A pry bar 114 is hinged to the second support column 112. The first end of the pry bar 114 is connected to a driving member 115. The second end of the pry bar 114 is used to contact the air spring body 116 and pry the air spring body 116 away from the mating surface between the air spring body 116 and the seat body 104.

[0036] According to the air spring disassembly device provided in this embodiment, the lever design of the pry bar 114 allows the operator to separate the airbag body 116 with only a small driving force, effectively improving efficiency compared to traditional manual disassembly methods. The controllability of the drive component 115 avoids the risk of component damage caused by traditional hammering disassembly. The adjustable structure and anti-slip design of the claw 102 ensure versatility for different specifications of air spring seats 104. The pressure sensor of the positioning block 108 monitors the clamping force in real time, preventing the cover 110 from deforming due to uneven force and protecting precision components. By replacing different specifications of the claw 102 and positioning block 108, it can adapt to the disassembly needs of various models of air springs, covering a variety of common air spring types. The multi-angle adjustment capability of the pry bar 114 allows it to adapt to the disassembly of airbag bodies 116 at different heights and angles, improving the applicability of the device.

[0037] Please continue reading Figures 1 to 4 The air spring disassembly device provided in this embodiment of the utility model achieves precise separation of each component of the air spring through modular design.

[0038] The retaining plate 100 is a circular metal disc with a diameter that matches the outer diameter of the air spring seat 104. Three to four retaining claws 102 are evenly distributed around the circumference of the retaining plate 100 and employ an adjustable structure. Each retaining claw 102 includes a fixed part and a movable part. The fixed part is connected to the retaining plate 100 by bolts, and the movable part is slidably connected to the fixed part by a slider. The radial position of the retaining claw 102 can be adjusted by adjusting the bolts. The retaining surface of the retaining claw 102 is designed as an arc shape that matches the edge of the air spring seat 104, and the surface is inlaid with an anti-slip rubber layer to ensure uniform clamping force and anti-slip properties.

[0039] The first support column 106 is a cylindrical structure with 2-3 columns evenly distributed around the circumference of the card plate 100. The positioning block 108 is located at the top of the first support column 106 and adopts an "L" shaped structure. The bottom surface of its horizontal section contacts the upper surface of the cover 110, and the inner side of its vertical section fits against the edge of the cover 110.

[0040] The second support column 112 is staggered with the first support column 106, and the number of them is the same as that of the first support column 106. A pry bar 114 is hinged to the middle of the second support column 112 via a spherical bearing, and can rotate ±45° in the vertical plane. The first end of the pry bar 114 is connected to a drive component 115 (such as a hydraulic cylinder or electric push rod) via a ball joint, and the other end of the drive component 115 is hinged to the bottom of the second support column 112. The second end of the pry bar 114 has a wedge-shaped structure with a wedge angle of 15-20°, used to insert into the mating surface between the airbag body 116 and the seat body 104.

[0041] The working process of the air spring disassembly device provided in this embodiment of the present invention is roughly as follows:

[0042] Place the card plate 100 under the air spring seat 104 and adjust the card claw 102 to lock it tightly against the edge of the seat 104;

[0043] The positioning block 108 on the first support column 106 clamps and lifts the air spring cover 110, ensuring that the cover 110 is fixed in place.

[0044] Start the drive unit 115, and the second end of the drive lever 114 is inserted into the mating surface between the airbag body 116 and the seat body 104. Using the lever principle, the airbag body 116 is pried away from the seat body 104.

[0045] According to one embodiment of the present invention, the air spring disassembly device further includes a base 118, a snap-fit ​​plate 100, a first support column 106 and a second support column 112 disposed on the base 118.

[0046] In one embodiment of this utility model, the base 118 is a rectangular plate structure, the retaining plate 100 is fixedly installed in the middle of the base 118, and the first support column 106 and the second support column 112 are distributed along the circumference of the retaining plate 100 and fixed on the base 118 to form a stable support structure. The bottom of the base 118 is provided with an anti-slip structure to enhance the stability of the device during use.

[0047] The base 118 provides a stable mounting foundation for the clamping plate 100, the first support column 106, and the second support column 112, ensuring that each component maintains a relatively fixed position when the air spring is disassembled, preventing the device from shaking and ensuring smooth disassembly operations. The anti-slip design of the base 118 allows it to be placed stably on the work surface, and the structural design of the base 118 facilitates the handling and repositioning of the device in different working scenarios, improving the device's practicality.

[0048] According to one embodiment of the present invention, a first guide rail 120 is provided on the base 118 along the radial direction of the card plate 100, a first sliding seat 122 is slidably provided on the first guide rail 120, and a first support column 106 is installed on the first sliding seat 122.

[0049] In one embodiment of this utility model, a first guide rail 120 is provided on the base 118 along the radial direction of the retaining plate 100, a first sliding seat 122 is slidably connected to the first guide rail 120, and a first support column 106 is mounted on the first sliding seat 122. By sliding the first sliding seat 122 on the first guide rail 120, the radial position of the first support column 106 along the retaining plate 100 can be adjusted.

[0050] The first support column 106 can slide along the first guide rail 120 with the first sliding seat 122. Its radial position can be flexibly adjusted according to the actual size and position of the air spring cover 110 to accommodate the disassembly requirements of air springs of different specifications, thus improving the versatility of the device. The sliding engagement structure between the first sliding seat 122 and the first guide rail 120 ensures smooth and precise position adjustment of the first support column 106, accurately clamping and lifting the air spring cover 110, laying a good foundation for subsequent disassembly operations.

[0051] According to one embodiment of the present invention, the first support column 106 includes:

[0052] Connecting segment 124 is disposed on the first sliding seat 122;

[0053] Telescopic section 126 is slidably connected to connecting section 124, and positioning block 108 is disposed at one end of telescopic section 126 away from connecting section 124.

[0054] In one embodiment of this utility model, the first support column 106 is composed of a connecting section 124 and a telescopic section 126. The connecting section 124 is fixed on the first sliding seat 122, and the telescopic section 126 is slidably connected to the connecting section 124. A positioning block 108 is installed at the end of the telescopic section 126 away from the connecting section 124. The height position of the positioning block 108 can be adjusted by sliding the telescopic section 126 on the connecting section 124.

[0055] The telescopic section 126 allows the height of the positioning block 108 to be adjusted according to the height of the air spring cover 110, ensuring that the positioning block 108 can accurately clamp and support the air spring cover 110 at different heights, further improving the device's adaptability to air springs of different specifications. The sliding connection structure between the telescopic section 126 and the connecting section 124 remains stable after being adjusted to a suitable height, making the clamping and lifting action of the positioning block 108 on the air spring cover 110 more reliable and preventing the cover 110 from shaking or shifting during disassembly.

[0056] According to one embodiment of the present invention, a second guide rail 128 is provided on the base 118 along the radial direction of the card plate 100, and a second sliding seat 130 is slidably provided on the second guide rail 128. The driving member 115 and the second support column 112 are mounted on the second sliding seat 130.

[0057] In one embodiment of this utility model, a second guide rail 128 is radially arranged on the base 118 along the retaining plate 100, and a second sliding seat 130 is slidably connected to the second guide rail 128. A driving member 115 and a second support column 112 are mounted on the second sliding seat 130. By sliding the second sliding seat 130 on the second guide rail 128, the radial position of the driving member 115 and the second support column 112 can be adjusted.

[0058] The driving component 115 and the second support column 112 can slide along the second guide rail 128 with the second sliding seat 130. The radial positions of the driving component 115 and the second support column 112 can be precisely adjusted according to the specific position of the mating surface between the air spring airbag body 116 and the seat body 104, allowing the second end of the pry bar 114 to accurately contact the airbag body 116 and perform the prying operation. By reasonably adjusting the positions of the driving component 115 and the second support column 112, the driving force of the driving component 115 can be more effectively transmitted through the pry bar 114 to the mating surface between the airbag body 116 and the seat body 104, improving disassembly efficiency and reducing energy loss.

[0059] According to one embodiment of the present invention, the output end of the drive member 115 is hinged to the pry bar 114.

[0060] In one embodiment of the present invention, the output end of the drive member 115 is connected to the pry bar 114 by a hinge, so that the pry bar 114 can rotate within a certain range relative to the output end of the drive member 115 to adapt to the change of the angle of the pry bar 114 during the disassembly process.

[0061] The hinged connection allows the pry bar 114 to be angled under the action of the drive unit 115, which can better fit the mating surfaces of the airbag body 116 and the seat 104, making the prying action smoother and avoiding situations where the pry bar 114 gets stuck or experiences uneven force due to a rigid connection. The hinged structure between the pry bar 114 and the output end of the drive unit 115 ensures that the driving force is applied to the airbag body 116 more effectively, reducing force loss caused by angular deviation, improving the utilization rate of the driving force, and making the disassembly operation more labor-saving.

[0062] According to one embodiment of the present invention, the driving member 115 includes:

[0063] Cylinder body 132, cylinder body 132 is connected to the second sliding seat 130;

[0064] Telescopic rod 134 is telescopically mounted on cylinder body 132, and the end of telescopic rod 134 facing away from cylinder body 132 is hinged to pry bar 114.

[0065] In one embodiment of this utility model, the driving component 115 consists of a cylinder 132 and a telescopic rod 134. The cylinder 132 is fixed on the second sliding seat 130, and the telescopic rod 134 can extend and retract within the cylinder 132. The end of the telescopic rod 134 away from the cylinder 132 is hinged to a pry bar 114. Through the extension and retraction of the telescopic rod 134, the pry bar 114 can be driven to pry the airbag body 116 away.

[0066] The cylinder 132 and telescopic rod 134 of the drive unit 115 provide a stable and controllable driving force. Operators can precisely control the prying force and movement of the pry bar 114 on the airbag 116 by controlling the extension speed and stroke of the telescopic rod 134, avoiding damage to the airbag 116 due to excessive or insufficient force. The telescopic function of the telescopic rod 134, combined with its hinged connection to the pry bar 114, allows the pry bar 114 to pry the airbag 116 from different positions and angles, adapting to varying adhesion conditions between the airbag 116 and the mating surface of the seat 104, thus improving the flexibility and success rate of the disassembly operation.

[0067] According to one embodiment of the present invention, the second support column 112 is disposed on the side of the cylinder body 132 near the card plate 100 and is fixedly connected to the second sliding seat 130.

[0068] In one embodiment of the present invention, the second support column 112 is fixedly installed on the second sliding seat 130 and is located on the side of the cylinder 132 near the card plate 100, forming a certain positional relationship with the cylinder 132, together constituting the support and drive structure of the pry bar 114.

[0069] The second support column 112 is located on the side of the cylinder body 132 near the retaining plate 100, forming a reasonable lever structure with the cylinder body 132 and the pry bar 114. This allows the driving force of the drive component 115 to be effectively transmitted through the pry bar 114 to the mating surface between the airbag body 116 and the seat body 104. Utilizing the lever principle, this achieves a labor-saving prying operation, reducing the operator's workload. The second support column 112 and the cylinder body 132 are fixed to the same second sliding seat 130, ensuring that their relative positions remain unchanged during disassembly. This makes the movement of the pry bar 114 more stable, preventing wobbling of the pry bar 114 due to changes in the support position and improving the reliability of the disassembly operation.

[0070] According to one embodiment of the present invention, a control valve 136 is provided on the cylinder body 132, and the control valve 136 is used to control the relative position of the telescopic rod 134 and the cylinder body 132.

[0071] In one embodiment of this utility model, a control valve 136 is installed on the cylinder 132. By operating the control valve 136, the telescopic rod 134 can be controlled to extend and retract within the cylinder 132, thereby adjusting the relative position of the telescopic rod 134 and the cylinder 132 and controlling the movement of the pry bar 114.

[0072] The control valve 136 precisely controls the extension and retraction position and speed of the telescopic rod 134, thereby accurately controlling the movement of the pry bar 114. This allows the second end of the pry bar 114 to accurately insert into the mating surface between the airbag body 116 and the seat 104, and to perform a prying operation with appropriate force and speed, improving the accuracy and safety of the disassembly operation. The control valve 136 also allows operators to easily control the movement of the drive component 115, flexibly adjusting the movement of the pry bar 114 according to the actual disassembly situation, reducing operational difficulty and improving work efficiency.

[0073] According to one embodiment of the present invention, the first support column 106 is arranged at intervals along the circumference of the card plate 100, and the interval between two adjacent first support columns 106 is 120 degrees; the second support column 112 is arranged at intervals along the circumference of the card plate 100, and the interval between two adjacent second support columns 112 is 120 degrees.

[0074] In one embodiment of the present invention, the first support column 106 is evenly distributed in the circumferential direction of the card plate 100, and the interval between two adjacent first support columns 106 is 120 degrees; the second support column 112 is also evenly distributed in the circumferential direction of the card plate 100, and the interval between two adjacent second support columns 112 is also 120 degrees, and the first support column 106 and the second support column 112 are staggered.

[0075] The first support columns 106 are evenly spaced, enabling them to clamp and lift the air spring cover 110 from multiple directions. This ensures even force distribution on the cover 110, preventing deformation or damage due to uneven force and guaranteeing its integrity. The second support columns 112 are evenly spaced and offset from the first support columns 106, allowing the pry bar 114 to pry the airbag body 116 from multiple directions. For mating surfaces with different adhesion conditions, the appropriate pry bar 114 position can be selected for operation, improving the success rate and efficiency of disassembly while ensuring even force distribution on the airbag body 116 and reducing the risk of damage.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
