Description

Technical Field

[0001] This utility model relates to the field of air spring assembly technology, and in particular to an automatic feeding mechanism for the bladder support ring of a rear air spring. Background Technology

[0002] Air springs, with their unique compressibility principle, have become highly successful high-performance elastic elements in automotive suspension systems in recent years. Continuous optimization and innovation in their design and manufacturing technologies have become a hot topic of exploration within the industry. To enhance the structural stability and positioning accuracy between the outer casing and the airbag, an innovative design concept has been proposed: using a large-size steel ring as an internal support structure, cleverly embedded inside a small-diameter airbag, and achieving a stable connection through precise clamping with the outer casing.

[0003] However, the current support ring assembly process still relies heavily on manual operation. Traditional methods often require manual placement of each support ring precisely into a specific slot on the guide plug, followed by the pushing action of the guide plug to insert the support ring into the airbag. During this process, movement of the guide plug can easily cause the support ring to loosen or fall off unexpectedly, severely hindering the rapid and accurate positioning of the support ring within the airbag. Furthermore, the non-standardization and high error rate of manual operation not only reduce the assembly efficiency of the support ring and airbag but also directly affect the overall assembly accuracy and product quality.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please refer to the following: Figures 1 to 9 To achieve the above objectives, this utility model provides the following technical solution:

[0027] An automatic feeding mechanism for the bladder support ring of a rear air spring includes a base 1, with an operating table 2 above the base 1; a support ring feeding assembly 3 is located above the operating table 2, and the support ring feeding assembly 3 is fixedly connected to the operating table 2; the support ring feeding assembly 3 includes a support frame 301, the lower end of which is fixedly connected to the upper surface of the operating table 2; a linear guide rail 302 is provided at the front end of the support frame 301 along its vertical direction, and a guide rail slider 303 is slidably connected to the linear guide rail 302; a "T"-shaped slide block 304 is provided at the front end of the guide rail slider 303, and the vertical end of the "T"-shaped slide block 304 is fixedly connected to the guide rail slider 303 by bolts, and the "T"-shaped slide block 304... A suspension support seat 305 is provided above the horizontal end of 04; the lower end of the suspension support seat 305 is fixedly connected to the "T"-shaped slide seat 304, and a servo motor 306 is provided at the upper end of the suspension support seat 305; the body of the servo motor 306 is fixedly connected to the top end of the suspension support seat 305, and the output shaft of the servo motor 306 passes through the top end of the suspension support seat 305 and extends upward; a rotating arm 307 is provided above the suspension support seat 305, and the lower middle of the rotating arm 307 is fixedly connected to the output shaft of the servo motor 306 through a flange 4; two sets of support ring clamping assemblies 5 with identical structures are symmetrically arranged at both ends of the rotating arm 307, and the support ring clamping assemblies 5 are fixedly connected to the rotating arm 307.

[0028] The base 1 serves as the supporting foundation for the entire mechanism, firmly fixed to the ground. The operating platform 2 is installed above the base 1, providing a flat working surface for installing and supporting other components. The support ring feeding assembly 3 is fixedly connected to the operating platform 2, responsible for the initial positioning and conveying of the support ring 8. The support frame 301 serves as the main structure of the support ring feeding assembly 3, with its lower end firmly connected to the operating platform 2 to ensure stability. A linear guide rail 302 is installed vertically at the front end of the support frame 301, allowing the guide rail slider 303 to slide on it, achieving vertical movement. The "T"-shaped slide 304 is fixedly connected to the guide rail slider 303 through its vertical end, sliding up and down on the linear guide rail 302 with the guide rail slider 303. A suspension support 305 is provided above the horizontal end of the "T"-shaped slide 304, used to support and fix the servo motor 306. The suspension support 305 and... The T-shaped slide 304 is fixedly connected to ensure the stability of the servo motor 306 and its driven rotating arm 307 during vertical movement. The servo motor 306 is mounted on the suspension support 305, and its output shaft passes through the top of the suspension support 305 and extends upward. The lower middle of the rotating arm 307 is fixedly connected to the output shaft of the servo motor 306 through the flange 4, so the rotation of the servo motor 306 can drive the rotating arm 307 to rotate. Two sets of identical support ring clamping assemblies 5 are symmetrically arranged at both ends of the rotating arm 307 for clamping and releasing the support ring 8. The support ring clamping assembly 5 is fixedly connected to the rotating arm 307 and rotates with the rotating arm 307. Each support ring clamping assembly 5 is designed with an external support claw 510 that can clamp the support ring 8. The clamping and releasing actions of the external support claw 510 are controlled by the stepper motor 501 drive mechanism.

[0029] In the initial state, the support ring feeding assembly 3 delivers the support ring 8 to the designated position, the servo motor 306 starts, and drives the rotating arm 307 to descend above the support ring 8; the support ring clamping assembly 5 starts and clamps the support ring 8; the servo motor 306 starts again and drives the rotating arm 307 to rotate to the target position (such as above the air spring bladder); the servo electric cylinder 308 adjusts the vertical position of the "T"-shaped slide 304 and the rotating arm 307 to ensure that the support ring 8 can be accurately delivered into the bladder; the support ring clamping assembly 5 releases the support ring 8, completing the ring delivery action; the servo motor 306 and the servo electric cylinder 308 and other drive mechanisms reset, ready for the next ring delivery operation.

[0030] Please refer to the following: Figure 3 , Figure 6 and Figure 7a , 7bAs one embodiment of the present invention, the support ring clamping assembly 5 includes a stepper motor 501, wherein the stepper motor 501 is fixedly connected to the rotating arm 307 through a motor mounting plate 502; the output shaft of the stepper motor 501 passes through the motor mounting plate 502 and extends downward, wherein a turntable 503 is provided below the motor mounting plate 502, and the upper end of the turntable 503 is fixedly connected to the output shaft of the stepper motor 501 through a coupling.

[0031] In the above-described scheme, the stepper motor 501 is a motor capable of precisely controlling the rotation angle and speed, suitable for applications requiring high-precision positioning. The stepper motor 501 is securely connected to the rotating arm 307 via the motor mounting plate 502, ensuring that it will not loosen or shift during rotation. The output shaft of the stepper motor 501 passes through the center of the motor mounting plate 502 and extends downwards, providing power to the turntable 503. The turntable 503 is a key rotating component in the support ring clamping assembly 5, and its upper end is fixedly connected to the output shaft of the stepper motor 501 via a coupling. The coupling is a device used to connect two shafts and transmit torque. It can compensate for small deviations between the two shafts, ensuring that the rotational power of the stepper motor 501 can be smoothly transmitted to the turntable 503. The design of the turntable 503 typically takes into account the layout and movement trajectory of the support ring clamping assembly 5 to ensure that the clamping action can be performed smoothly.

[0032] When it is necessary to clamp the support ring 8, the stepper motor 501 receives a control signal and starts rotating. The rotation of the stepper motor 501 is transmitted to the turntable 503 through the coupling, causing the turntable 503 and the support ring clamping assembly 5 on it to rotate or move. The support ring clamping assembly 5 gradually approaches the support ring 8 according to the preset trajectory and speed, and finally clamps it. After clamping the support ring 8, the stepper motor 501 may continue to rotate to adjust the orientation or position of the support ring 8, in preparation for subsequent conveying and positioning. When it is necessary to release the support ring 8 to the target position, the stepper motor 501 receives a control signal again and rotates in the opposite direction, causing the support ring clamping assembly 5 to gradually move away from the support ring 8 and release it. Through the above workflow, the support ring clamping assembly 5 can accurately clamp and release the support ring 8, providing a stable and reliable clamping function for the entire automatic feeding mechanism.

[0033] Please refer to the following: Figure 7a , 7b As one embodiment of this utility model, three sets of arc-shaped guide holes 504 are evenly distributed on the disc body of the turntable 503, wherein the arc-shaped guide holes 504 extend outward from the center of the turntable 503; three sets of limiting slide rails 505 are evenly distributed below the motor mounting plate 502, wherein the three sets of limiting slide rails 505 are radially distributed below the motor mounting plate 502; each limiting slide rail 505 is slidably connected to a limiting slider 506, wherein a connecting plate 507 is fixedly installed at the connecting end of the limiting slider 506.

[0034] In the above-described scheme, the turntable 503, as one of the core components of the support ring clamping assembly 5, is responsible for driving the outer support claw 510 to rotate. Three sets of arc-shaped guide holes 504 are evenly distributed on the turntable 503, extending outwards from the center of the turntable 503. The arc-shaped guide holes 504 are designed to guide the limiting slider 506 and its connected connecting plate 507 and outer support claw 510 to move along a predetermined trajectory when the turntable 503 rotates. The shape and layout of the arc-shaped guide holes 504 are precisely calculated to ensure that the slider maintains a stable path and speed during movement. Three sets of limiting slide rails 505 are evenly distributed below the motor mounting plate 502, radiating outwards from the center of the motor mounting plate 502. The main function of the distribution and limiting slide rails 505 is to restrict the movement trajectory of the limiting sliders 506 and prevent them from deviating from the predetermined path during movement. Each set of limiting slide rails 505 has a limiting slider 506 slidably connected to it, allowing it to move freely on the limiting slide rails 505. The design of the limiting slider 506 typically includes a sliding surface that matches the limiting slide rail 505 and a connecting end for connecting other components. A connecting plate 507 is fixedly installed at the connecting end of the limiting slider 506. The connecting plate 507 acts as a bridge between the limiting slider 506 and the external support claw 510, transmitting the movement and power of the limiting slider 506. The design of the connecting plate 507 typically takes into account the layout and movement requirements of the external support claw 510 to ensure that the two can work smoothly together.

[0035] The turntable 503 remains stationary, the limiting slider 506 is located at the starting position of the limiting slide rail 505, and the connecting plate 507 and the outer support claw 510 are in a standby state. When it is necessary to clamp or release the support ring 8, the turntable 503 begins to rotate. The rotation of the turntable 503 guides the limiting slider 506 to move along a predetermined trajectory through the arc-shaped guide hole 504. Under the constraint of the limiting slide rail 505 and the arc-shaped guide hole 504, the limiting slider 506 moves smoothly along the predetermined path. The movement of the limiting slider 506 is transmitted to the outer support claw 510 through the connecting plate 507, thereby driving the outer support claw 510 to perform corresponding clamping or releasing actions. When the limit slider 506 moves to the designated position, the outer support claw 510 completes the action of clamping or releasing the support ring 8. At this time, the turntable 503 may continue to rotate to adjust the orientation or position of the support ring 8. After completing the clamping or releasing action, the turntable 503 rotates in the opposite direction, driving the limit slider 506, the connecting plate 507 and the outer support claw 510 back to the initial position, preparing for the next operation. Through the above workflow, the turntable 503, the arc-shaped guide hole 504, the limit slide rail 505, the limit slider 506 and the connecting plate 507 work together to achieve precise control and stable movement of the support ring clamping assembly 5.

[0036] Please refer to the following: Figure 6 , Figure 7a , 7b and Figure 8 As one embodiment of the present utility model, a support arm 508 is fixedly installed at one end of the connecting plate 507, and the other end of the connecting plate 507 extends above the turntable 503; a pulley 509 is provided at one end of the connecting plate 507 near the turntable 503, wherein the pulley 509 is disposed in the arc-shaped guide hole 504, and the pulley 509 is slidably connected to the arc-shaped guide hole 504.

[0037] In the above-described scheme, the connecting plate 507 serves as a key connecting component. A support arm 508 is fixedly mounted on one end of the connecting plate 507, and the other end extends above the turntable 503. The support arm 508 connects to the outer support claw 510, ensuring that the outer support claw 510 can stably follow the movement of the turntable 503. The support arm 508 is connected to the slider via the connecting plate 507, and its design typically considers the weight, movement trajectory, and required support force of the outer support claw 510. The length and angle of the support arm 508 are precisely calculated to ensure that the outer support claw 510 maintains a stable posture and position during movement. A pulley 509 is provided at the end of the connecting plate 507 near the turntable 503. 509 is designed to slide within the arc-shaped guide hole 504; wherein, pulley 509 typically has low friction and wear-resistant characteristics to ensure smooth movement within the arc-shaped guide hole 504 when the turntable 503 rotates; the arc-shaped guide hole 504 is a guide channel evenly distributed on the turntable 503, used to guide pulley 509, connecting plate 507, support arm 508 and outer support claw 510 to move along a predetermined trajectory; the shape and layout of the arc-shaped guide hole 504 are precisely calculated to ensure that pulley 509 can maintain a stable path and speed during movement, while reducing friction and wear. This design not only improves the automation level and work efficiency of the system, but also ensures the accuracy and reliability of the clamping action.

[0038] Please refer to the following: Figure 6 , Figure 9 As one embodiment of the present utility model, an outer support claw 510 is provided below the support arm 508, wherein the upper end of the outer support claw 510 is bent outward and fixedly connected to the support arm 508; the lower end of the outer support claw 510 is provided with an outwardly protruding claw head 6, wherein a limiting groove 7 is provided on the outer wall of the claw head 6, wherein the limiting groove 7 is adapted to the support ring 8.

[0039] In the above-described scheme, the support arm 508, as a key component for connection and support, is fixedly connected to the connecting plate 507 at one end, while the other end supports the outer support claw 510. The design of the support arm 508 ensures the stability and reliability of the outer support claw 510 during rotation and movement. The outer support claw 510 is the main component for clamping the support ring 8, and its shape and structure are designed to firmly clamp the support ring 8. The upper end of the outer support claw 510 is bent outward and fixedly connected to the support arm 508. This design increases the stability of the outer support claw 510 and facilitates its connection with the support arm 508. The support arm 508 is connected; the lower end of the outer support claw 510 is provided with an outwardly protruding claw head 6, which is the part that actually contacts the support ring 8 and generates clamping force; the shape and size of the claw head 6 are precisely designed to ensure that it can fit tightly with the support ring 8 and achieve a stable clamping effect; a limiting groove 7 is opened on the outer wall of the claw head 6, which is specially designed to adapt to specific parts of the support ring 8; the shape, size and position of the limiting groove 7 are precisely calculated to ensure that the support ring 8 can be firmly clamped during the clamping process to prevent it from slipping or moving.

[0040] Before clamping the support ring 8, the turntable 503 is stationary, and the outer support claw 510 is in its initial position. Simultaneously, the support ring 8 is placed in a predetermined position, awaiting clamping. The servo motor 306 drives the rotating arm 307 to rotate, thereby moving the support ring clamping assembly 5 above the support ring 8. Next, the stepper motor 501 is started, driving the turntable 503 to rotate. Through the transmission of components such as the connecting plate 507 and the support arm 508, the outer support claw 510 moves to above the support ring 8. As the turntable 503 further rotates and moves, the claw head 6 of the outer support claw 510 gradually approaches and contacts the support ring 8. When the claw head 6 is fully in contact with the support ring 8 and generates a certain clamping force, the limiting slot 7 firmly clamps the support ring. A specific part of the support ring 8 achieves a stable clamping effect. After clamping the support ring 8, the servo motor 306 is activated to drive the rotating arm 307 to rotate, thereby transporting the support ring 8 to the desired position. Throughout the movement, the outer support jaw 510 maintains a firm grip on the support ring 8 through the limiting slot 7, preventing it from slipping or moving. When it is necessary to release the support ring 8, the stepper motor 501 controls the turntable 503 to rotate in the opposite direction, causing the outer support jaw 510 to gradually move away from the support ring 8. When the jaw head 6 separates from the support ring 8, the support ring 8 is released and placed in the target position. This achieves precise clamping, stable movement, and reliable release of the support ring 8. This design not only improves the automation level and work efficiency of the system but also ensures the accuracy and reliability of the clamping action.

[0042] In the above-described scheme, the "T"-shaped slide 304 is a sliding component with a specific shape, designed to slide stably in the horizontal direction; the servo electric cylinder 308 is a linear drive device integrating a servo motor 306 and a lead screw transmission mechanism, featuring high precision, high reliability, and ease of control; the servo electric cylinder 308 is vertically arranged, with its lower end penetrating the operating table 2 and fixedly connected to the base 1, ensuring the stability of the entire device during operation; the top of the piston rod of the servo electric cylinder 308 is fixedly connected to the lower end of the "T"-shaped slide 304, and the extension and retraction of the piston rod drives the "T"-shaped slide 304 to move up and down.

[0044] In the above-described scheme, the suspension support 305 is a key component used to support and fix the rotating arm 307 or other mechanisms that require rotation. The suspension support 305 is typically designed to be robust enough to withstand the weight of the rotating arm 307 and its supported components, as well as the forces generated during rotation. The first limiting block 9 is located at the upper end of the suspension support 305 to limit the rotation range of the rotating arm 307. The first limiting block 9 is a protruding structure that can be block-shaped, plate-shaped, or other shapes, depending on application requirements and design preferences. The position and dimensions of the first limiting block 9 are precisely calculated to ensure rotation... The rotating arm 307 will not exceed the predetermined safety range during rotation. Two second limit blocks 10 are symmetrically arranged at the lower end of the rotating arm 307. The second limit blocks 10 are adapted to the first limit blocks 9 and are used to cooperate with the first limit blocks 9 to jointly limit the rotation range of the rotating arm 307. The first limit blocks 9 are usually symmetrical to ensure that the rotating arm 307 can be smoothly and evenly restricted during rotation. The shape and size of the second limit blocks 10 match the first limit blocks 9 to ensure that the two can fit tightly when in contact, preventing the rotating arm 307 from exceeding the predetermined rotation range.
