Description

Technical Field

[0001] This utility model relates to the technical field of tire manufacturing, and in particular to an aircraft tire blank shaping and expansion support device. Background Technology

[0002] For large-size tires, the tire blanks are large, and the treads are mostly wound. After the tire blanks produced by the bias-ply engineering tire forming process are wound, they are directly stored on the tire blank truck. During storage, the tire blanks are prone to deformation and collapse, compromising the quality of the tire blanks. Existing technology announcement CN218464252U proposes a bias-ply engineering tire blank support device, including two support parts arranged opposite each other, with the opposite faces of the two support parts adapted to the inner wall surface of the tire blank; a telescopic mechanism, including a forward threaded rod, a reverse threaded rod, and a rotating threaded sleeve; one end of the forward threaded rod is fixedly connected to the support part, and the other end is threadedly connected to the rotating threaded sleeve; one end of the reverse threaded rod is fixedly connected to the other support part, and the other end is threadedly connected to the rotating threaded sleeve. Through the arrangement of the forward threaded rod, reverse threaded rod, and rotating threaded sleeve, the forward and reverse threaded rods can rotate synchronously in both directions by rotating the rotating threaded sleeve until the two threaded rods abut against the inner wall surface of the tire blank, thus completing the support of the tire blank. However, the adjustment is relatively troublesome, there are fewer support points for the tire blank, which has a certain impact on tire shaping. The tire is prone to stress concentration, which can cause deformation of the unshaped tire and affect the quality of the tire. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an aviation tire blank shaping expansion support device that improves the shaping quality of tires, is applicable to tires of different sizes, is easy to adjust, and helps improve work efficiency.

[0004] This utility model discloses an aircraft tire blank shaping and expansion support device, comprising an intermediate cylinder, a support component, an adjusting component, and a guiding component. The support component is installed on the outer wall of the intermediate cylinder, and the adjusting component is installed inside the intermediate cylinder, with the adjusting component internally connected to the support component. A guiding component is installed between the intermediate cylinder and the adjusting component. The tire blank is supported by the support component, with multiple support points to ensure the shaping quality of the tire. The adjusting component can adjust the support position, is suitable for tires of different sizes, and is convenient to adjust, which helps to improve work efficiency. The guiding component can improve the connection strength between the adjusting component and the intermediate cylinder, ensuring stability.

[0005] Preferably, the support component includes multiple support cylinders, multiple adjusting cylinders, multiple support parts, and a disassembly assembly. The multiple support cylinders are axially distributed and installed on the outer wall of the intermediate cylinder. The adjusting cylinders are installed inside the support cylinders, and the support parts are installed at the outer ends of the adjusting cylinders through the disassembly assembly. The support parts are supported by the support cylinders and adjusting cylinders, so that the support parts support the tire blank. The multiple support parts provide support to ensure the tire's shaping quality.

[0006] Preferably, the disassembly assembly includes multiple connecting seats, multiple mounting seats, multiple pins, and multiple wing nuts. The connecting seats are mounted on the adjusting cylinder, and the mounting seats are mounted in the middle of the inner wall of the support. The mounting seats and connecting seats are connected by pins, and a wing nut is screwed onto the left end of the pin. By loosening the wing nut and pulling out the pin, the support can be removed from the adjusting cylinder, making it convenient to select the appropriate support according to the tire model, thus facilitating use and improving applicability.

[0007] Preferably, the adjusting component includes a rotating shaft, a bevel gear, multiple threaded rods, multiple drive bevel gears, a knob, and a limiting assembly. The rotating shaft is rotatably mounted inside the intermediate cylinder, and a bevel gear is mounted on the rotating shaft. The threaded rods are rotatably mounted inside the support cylinder, and the adjusting cylinder is screwed onto the outer wall of the threaded rods. The threaded rods extend into the intermediate cylinder and are fitted with drive bevel gears, which mesh with the bevel gears. The input end of the rotating shaft passes through the outer wall of the intermediate cylinder and is fitted with a knob. Rotating the knob drives the rotating shaft to rotate, and the rotating shaft drives the drive bevel gears to rotate through the bevel gears, causing the guide slide rod to rotate inside the support cylinder. This allows the adjusting cylinder to extend out of the support cylinder, adjusting the support position of the support part. This is suitable for tires of different sizes, improving the applicability.

[0008] Preferably, the limiting component includes multiple sets of guide slide rods and multiple sets of limiting sliders. Multiple limiting guide grooves are provided on the inner wall of the support cylinder, and the guide slide rods are installed in the limiting guide grooves. Multiple limiting sliders are installed on the outer wall of the adjusting cylinder, and the limiting sliders are slidably installed on the outer wall of the guide slide rods. When the adjusting cylinder moves inside the support cylinder, it drives the limiting sliders to slide on the guide slide rods to limit and guide them, ensuring stability during movement and improving support strength.

[0009] Preferably, the guiding component includes a guide turntable and a connecting plate. The connecting plate is installed inside the intermediate cylinder, and the rotating shaft is rotatably installed in the middle of the connecting plate. A guide groove is opened on the right wall of the intermediate cylinder, and the guide turntable is rotatably installed in the guide groove. The middle part of the guide turntable is coaxially installed on the outer wall of the rotating shaft. When the rotating shaft rotates, it drives the guide turntable to rotate in the guide groove. At the same time, the rotating shaft rotates on the connecting plate to guide and limit it, increase the connection strength, and ensure stability.

[0010] Preferably, it also includes a limiting plate, a locking seat, and a locking bolt. The limiting plate is installed through the middle cylinder at the left end of the rotating shaft, and a locking seat is installed at the lower end of the left side wall of the middle cylinder.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5As shown, multiple support cylinders 2 are axially distributed and installed on the outer wall of the intermediate cylinder 1. An adjusting cylinder 3 is installed inside the support cylinder 2, and a connecting seat 4 is installed on the adjusting cylinder 3. An mounting seat 5 is installed in the middle of the inner wall of the support part 6. The mounting seat 5 and the connecting seat 4 are connected by a pin 7. A wing nut 8 is screwed onto the left end of the pin 7. A rotating shaft 9 is rotatably installed inside the intermediate cylinder 1, and a bevel gear 10 is installed on the rotating shaft 9. A threaded rod 11 is rotatably installed inside the support cylinder 2. The adjusting cylinder 3 is screwed onto the outer wall of the threaded rod 11. The threaded rod 11 extends into the intermediate cylinder 1 and is equipped with a driving bevel gear 12, which meshes with the bevel gear 10. The input end of the rotating shaft 9 passes through the outer wall of the intermediate cylinder 1. A knob 16 is installed on the wall. Multiple limiting guide grooves are opened on the inner wall of the support cylinder 2. The guide slide rod 13 is installed in the limiting guide groove. Multiple limiting sliders 14 are installed on the outer wall of the adjusting cylinder 3. The limiting sliders 14 are slidably installed on the outer wall of the guide slide rod 13. A connecting plate 20 is installed inside the intermediate cylinder 1. The rotating shaft 9 is rotatably installed in the middle of the connecting plate 20. A guide groove is opened on the right wall of the intermediate cylinder 1. The guide turntable 15 is rotatably installed in the guide groove. The middle part of the guide turntable 15 is coaxially installed on the outer wall of the rotating shaft 9. The left end of the rotating shaft 9 passes through the intermediate cylinder 1 and is installed with a limiting plate 17. A locking seat 18 is installed at the lower end of the left side wall of the intermediate cylinder 1. A locking bolt 19 is screwed on the locking seat 18.

[0020] The support part 6 is supported by the support cylinder 2 and the adjusting cylinder 3, allowing the support part 6 to support the tire blank. Multiple support parts 6 ensure the tire's shaping quality. Loosening the wing nut 8 and pulling out the pin 7 allows the support part 6 to be removed from the adjusting cylinder 3, facilitating the selection of the appropriate support part 6 according to the tire model, improving ease of use and applicability. Rotating the knob 16 drives the rotating shaft 9 to rotate, which in turn drives the drive bevel gear 12 through the bevel gear 10, causing the guide slide rod 13 to rotate inside the support cylinder 2. This pushes the adjusting cylinder 3 to extend out from inside the support cylinder 2, adjusting the support position of the support part 6. For tires of different sizes, to improve applicability, when the adjusting cylinder 3 moves within the support cylinder 2, it drives the limiting slider 14 to slide on the guide slide rod 13, limiting and guiding it to ensure stability during movement and improve support strength. When the rotating shaft 9 rotates, it drives the guide turntable 15 to rotate within the guide groove. At the same time, the rotating shaft 9 rotates on the connecting plate 20, guiding and limiting it to increase connection strength and ensure stability. When the rotating shaft 9 rotates for adjustment, it drives the limiting plate 17 to rotate. After adjustment, the locking bolt 19 is tightened to limit the limiting plate 17, thereby locking and limiting the rotating shaft 9 to ensure stability.

[0021] like Figures 1 to 5As shown, this utility model discloses an aircraft tire blank shaping and expansion support device. During operation, rotating the knob 16 drives the rotating shaft 9 to rotate. The rotating shaft 9, through the bevel gear 10, drives the drive bevel gear 12 to rotate, causing the guide slide rod 13 to rotate within the support cylinder 2. This pushes the adjusting cylinder 3 to extend out of the support cylinder 2, adjusting the support position of the support part 6. When the rotating shaft 9 rotates for adjustment, it drives the limiting disc 17 to rotate. After adjustment, tightening the locking bolt 19 limits the limiting disc 17, thereby locking and limiting the rotating shaft 9. The support part 6 is supported by the support cylinder 2 and the adjusting cylinder 3, thus supporting the tire blank. Multiple support parts 6 provide support, ensuring the tire's shaping quality. When the adjusting cylinder 3 moves within the support cylinder 2, it drives the limiting slider 14 to slide on the guide slide rod 13, limiting and guiding it to ensure stability during movement. Loosening the wing nut 8 and pulling out the pin shaft 7 allows the support part 6 to be removed from the adjusting cylinder 3, facilitating the selection of the appropriate support part 6 according to the tire model, making it convenient to use.
