[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please refer to the following: Figures 1 to 7 To achieve the above objectives, this utility model provides the following technical solution:

[0025] A ring feeding mechanism for a rear air spring bladder support ring includes a base 1, with an operating platform 2 above the base 1; a ring feeding assembly 3 is located above the operating platform 2, and the ring feeding assembly 3 is fixedly connected to the operating platform 2; the ring feeding assembly 3 includes a fixed support 301, with its lower end fixedly connected to the operating platform 2; a worm gear screw jack 302 is located at the front end above the fixed support 301, and a servo drive motor 303 is located at the rear end above the fixed support 301; the output shaft of the servo drive motor 303 is fixedly connected to the input end of the worm gear screw jack 302 via a coupling 304; a flange 4 is fixedly installed on the upper end of the lifting screw 305 of the worm gear screw jack 302, with a lifting plate 5 located above the flange 4; a ring placing assembly 6 is located above the lifting plate 5, and multiple support columns 7 are provided between the ring placing assembly 6 and the lifting plate 5.

[0026] The base 1 serves as the supporting foundation for the entire mechanism, with an operating platform 2 mounted on top, providing an installation platform for the ring feeding assembly 3 and the ring placing assembly 6. The ring feeding assembly 3 includes a fixed support 301, a worm gear screw jack 302, and a servo drive motor 303. The lower end of the fixed support 301 is fixedly connected to the operating platform 2 to ensure the stability of the ring feeding assembly 3. The worm gear screw jack 302 is installed at the front end of the fixed support 301 to realize the lifting action. The servo drive motor 303 is installed at the rear end of the fixed support 301, and its output shaft is fixedly connected to the input end of the worm gear screw jack 302 through a coupling 304. By controlling the operation of the servo drive motor 303, the worm gear screw jack can be precisely controlled. The lifting speed and position of the screw jack 302; a flange 4 is fixedly installed on the upper end of the lifting screw 305 of the screw jack 302, and a lifting plate 5 is provided above the flange 4; when the servo drive motor 303 runs, it drives the input end of the screw jack 302 to rotate through the coupling 304, thereby driving the lifting screw 305 to rise and fall; the lifting action of the lifting screw 305 is transmitted to the lifting plate 5 through the flange 4, realizing the lifting movement of the lifting plate 5; the ring mounting assembly 6 is installed above the lifting plate 5 and is fixedly connected to the lifting plate 5 through multiple support columns 7; the ring mounting assembly 6 is used to support and position the support ring 17, ensuring that the support ring 17 can be accurately placed in the predetermined position.

[0027] During operation, the worm gear screw jack 302 is first controlled by the servo drive motor 303 to lower the lifting plate 5 to a suitable position so that the support ring 17 can be placed on the ring mounting assembly 6. Then, the ring mounting assembly 6 is controlled to move the support ring 17 to a predetermined position and position it. Finally, the worm gear screw jack 302 is controlled by the servo drive motor 303 to raise the lifting plate 5 again and send the support ring 17 to the subsequent process for further processing or assembly.

[0028] Please refer to the following: Figure 2 , Figure 4As an embodiment of the present utility model, the ring assembly 6 includes a fixing plate 601, wherein the lower periphery of the fixing plate 601 is fixedly connected to the lifting plate 5 by a support column 7; a stepper motor 602 is installed in the middle of the lower end of the fixing plate 601, wherein the output shaft of the stepper motor 602 passes through the fixing plate 601 and extends upward; a turntable 603 is provided on the fixing plate 601, wherein the lower end of the turntable 603 is fixedly connected to the output shaft of the stepper motor 602.

[0029] In the above-described scheme, the fixed plate 601 serves as the basic component of the entire ring-positioning assembly 6. Its lower periphery is fixedly connected to the lifting plate 5 via support columns 7 to ensure the stability of the ring-positioning assembly 6. The stepper motor 602 is installed at the lower middle position of the fixed plate 601, and its output shaft passes through the fixed plate 601 and extends upward to drive the turntable 603 to rotate. The turntable 603 is fixedly connected to the output shaft of the stepper motor 602 to support the support ring 17. When it is necessary to clamp the support ring 17, the control system sends a command to the stepper motor 602 to start it. After receiving the command, the output shaft of the stepper motor 602 will rotate according to the preset step angle and speed. Since the turntable 603 is fixedly connected to the output shaft of the stepper motor 602, the turntable 603 will also rotate with the rotation of the stepper motor 602. As the turntable 603 rotates, it drives the ring-positioning assembly 6 to clamp the support ring 17, thereby realizing the precise positioning function of the support ring 17. This design not only improves production efficiency and product quality, but also provides a strong guarantee for the smooth operation of subsequent processes.

[0030] Please refer to the following: Figure 4 , Figure 6 As an embodiment of the present utility model, three sets of arc-shaped guide holes 8 are evenly distributed on the disc body of the turntable 603, wherein the arc-shaped guide holes 8 extend outward from the center of the turntable 603.

[0031] In the above-described scheme, the design of the arc-shaped guide holes 8 allows them to provide a smooth guide path along the circumference of the turntable 603. During the operation of the ring-positioning assembly 6, the turntable 603 carries the support ring 17. As the turntable 603 rotates, the three sets of arc-shaped guide holes 8 move accordingly, providing guidance and positioning for the components that mate with them. The design of these arc-shaped guide holes 8 ensures that the components that mate with them can move along a predetermined path, thereby achieving precise positioning of the support ring 17. In addition, the design of the arc-shaped guide holes 8 also makes the structure of the ring-positioning assembly 6 more compact and stable, improving the reliability and durability of the entire mechanism. During the ring-positioning and feeding process of the rear air spring bladder support ring 17, the design of the arc-shaped guide holes 8 makes it easier for the support ring 17 to be placed in the predetermined position and to remain stable during rotation. This is of great significance for improving production efficiency, reducing manual intervention, and lowering production costs.

[0032] Please refer to the following: Figure 4 , Figure 5 As one embodiment of the present utility model, three sets of limiting slide rails 9 are evenly distributed on the upper end of the fixing plate 601, wherein the three sets of limiting slide rails 9 are radially and equidistantly distributed; a limiting slider 10 is slidably connected on the limiting slide rail 9, wherein a support plate 11 is fixedly installed on the upper end of the limiting slider 10.

[0033] In the above-described scheme, three sets of limiting slide rails 9 are evenly distributed on the upper end of the fixed plate 601. These limiting slide rails 9 are radially and equidistantly distributed to form a stable support and guide structure. Each limiting slide rail 9 is slidably connected to a limiting slider 10. These limiting sliders 10 can move freely on the limiting slide rail 9, but are limited by the guiding effect of the limiting slide rail 9, ensuring that they can only move along a predetermined path. A support plate 11 is fixedly installed on the upper end of the limiting slider 10.

[0034] The design of the limiting slide rail 9 and the limiting slider 10 not only provides stable support and guidance, but also enables the support plate 11 to switch quickly and accurately between different working positions. During the loading process of the rear air spring bladder support ring 17, this design makes it easier for the support ring 17 to be placed in the predetermined position and can be quickly moved to other positions for further processing or assembly when needed. In addition, due to the precise control of the limiting slide rail 9 and the limiting slider 10, the stability and accuracy of the support ring 17 during movement can be ensured, thereby improving production efficiency and product quality.

[0035] Please refer to the following: Figure 4 , Figure 5 and Figure 7 As an embodiment of the present utility model, a ring base 12 is provided above the support plate 11, wherein the lower end of the ring base 12 is fixedly connected to the support plate 11; a ring platform 13 is provided on the inner wall of the upper end of the ring base 12, wherein the ring platform 13 has a stepped structure.

[0036] In the above-described scheme, a ring-placement base 12 is provided above the support plate 11. This ring-placement base 12 is fixedly connected to the support plate 11, ensuring its stability and reliability. The upper inner wall of the ring-placement base 12 is designed with a ring-placement platform 13, which is a stepped structure with planes of different heights to accommodate and support support rings 17 of different sizes or shapes. When it is necessary to place the bladder support ring 17, the support plate 11 and the ring-placement base 12 on it are first moved to a predetermined position by controlling the limiting slide rail 9 and the limiting slider 10. Then, the bladder support ring 17 is placed on the ring-placement platform 13. Since the ring-placement platform 13 is a stepped structure, a suitable plane can be selected for placement according to the specific size or shape of the support ring 17. The design of the ring-placement platform 13 not only provides stable support but also ensures the accuracy and stability of the bladder support ring 17 during placement.

[0037] Please refer to the following: Figure 4 , Figure 5 As one embodiment of the present utility model, the support plate 11 extends to the bottom of the turntable 603 at the end away from the ring base 12 and is provided with a pulley 14, wherein the pulley 14 is disposed in the arc-shaped guide hole 8 and the pulley 14 is slidably connected to the arc-shaped guide hole 8.

[0038] In the above-described scheme, one end of the support plate 11 extends away from the ring base 12 and downwards towards the turntable 603, forming a cantilever structure. A pulley 14 is provided at the end of this cantilever structure, which matches the arc-shaped guide hole 8 on the turntable 603. The pulley 14 is slidably connected to the inner wall of the arc-shaped guide hole 8 through its rim, ensuring that the support plate 11 and the ring base 12 on it can move smoothly along the path of the arc-shaped guide hole 8. When the turntable 603 rotates under the drive of the stepper motor 602, the arc-shaped guide hole 8 also moves accordingly. Because the pulley 14 is slidably connected to the arc-shaped guide hole 8, the support plate 11 and the ring base 12 on it will move smoothly along the path of the arc-shaped guide hole 8. The movement is synchronized along the path; this movement mechanism ensures that the support plate 11 and its ring base 12 can move smoothly with the rotation of the turntable 603 without deviation or shaking; at the same time, the sliding connection design between the pulley 14 and the arc-shaped guide hole 8 not only provides a stable movement path, but also ensures the accuracy and stability of the support plate 11 and its ring base 12 during the movement process; this design enables the support plate 11 to move precisely to the predetermined position with the rotation of the turntable 603, thereby achieving precise positioning of the support ring 17. This design not only improves production efficiency, but also reduces manual intervention and production costs, and enhances the flexibility and adaptability of the entire ring assembly 6.

[0039] Please refer to the following: Figure 1 , Figure 2 and Figure 3As one embodiment of this utility model, two limiting guide sleeves 15 are symmetrically arranged on one end of the fixed support 301 near the worm gear screw jack 302. A limiting guide shaft 16 is provided inside the limiting guide sleeve 15, and the limiting guide shaft 16 is slidably connected to the limiting guide sleeve 15. The upper end of the limiting guide shaft 16 is fixedly connected to the lower end of the lifting plate 5, and the lower end of the limiting guide shaft 16 extends downward and passes through the operating table 2. The operating table 2 is provided with a clearance hole corresponding to the limiting guide shaft 16.

[0040] In the above-described scheme, the fixed support 301 serves as the supporting foundation for the entire mechanism. Two limiting guide sleeves 15 are symmetrically arranged at one end of the fixed support 301 near the worm gear screw jack 302. Each limiting guide sleeve 15 has a precision sliding channel designed to accommodate and guide the limiting guide shaft 16. The limiting guide shaft 16 is a precision cylindrical component, its upper end fixedly connected to the lower end of the lifting plate 5. When the worm gear screw jack 302 starts, it drives the lifting plate 5 to move up and down. Since the lower end of the lifting plate 5 is fixedly connected to the limiting guide shaft 16, the limiting guide shaft 16 also moves up and down with the movement of the lifting plate 5. During movement, the limiting guide shaft 16 slides within the limiting guide sleeve 15. This sliding connection ensures the stability and accuracy of the lifting plate 5 during movement. Simultaneously, the design of the limiting guide sleeve 15 and the limiting guide shaft 16 not only provides stable support but also precisely limits and guides the movement path of the lifting plate 5. This design ensures that the lifting plate 5 will not deviate from the predetermined path during movement, thereby improving the stability and reliability of the entire mechanism. Furthermore, the sliding connection between the limiting guide sleeve 15 and the limiting guide shaft 16 also has a certain buffering effect, reducing the impact and vibration of the lifting plate 5 during movement.
