Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire processing, and in particular to an aircraft tire forming blank fixing device. Background Technology

[0002] The tire blank of an aircraft tire is a semi-finished product before vulcanization. It is composed of multiple layers of rubber and reinforcing materials through a molding process, including components such as the tread, sidewall, belt layer, carcass ply, and inner liner, but it has not yet been finalized through the vulcanization process. During the molding process, the tire blank is not vulcanized, and the rubber is soft, making it susceptible to deformation under external forces. Fixing devices, through mechanical clamping or mold positioning, can strictly limit the displacement of the tire blank during rolling, bonding, and cutting processes, preventing dimensional deviations caused by deformation.

[0003] The existing Chinese utility model patent with application number CN201020215571.4 relates to a special fixing device for engineering tire blanks, including a base, column, support frame, straight arm, curved arm and reinforcing rib, which can ensure the service life of the entire device and reduce the cost of use.

[0004] However, in actual use, the above-mentioned device can easily cause excessive local stress on the tire during the load-bearing process, resulting in deformation. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides an aviation tire forming blank fixing device that provides power for tire rotation through a driving device, facilitating the tire's own rotation and switching of its spatial position, supports and fixes the inside of the tire through a support device, increases the force-bearing area of ​​the tire support and fixation, prevents excessive local force from causing tire deformation, and provides auxiliary support for the lower part of the tire through a bottom support device, thereby improving the stability and practicality of the device.

[0006] This utility model discloses an aircraft tire forming blank fixing device, comprising a driving device, a supporting device, and a bottom support device. The supporting device is mounted on the driving device, and the bottom support device is mounted on the driving device. The driving device provides power for the tire to rotate, facilitating the tire's own rotation and changing its spatial position. The supporting device supports and fixes the inside of the tire, increasing the force-bearing area of ​​the tire support and preventing excessive local stress from causing tire deformation. The bottom support device provides auxiliary support for the lower part of the tire, improving the stability and practicality of the device.

[0007] Preferably, the drive device includes a frame, a main shaft, a support frame, a reducer, and a motor. The main shaft is mounted on the upper part of the frame via bearings. A support frame is provided on the rear end face of the frame, and a reducer is mounted on the rear end face of the support frame. The motor is mounted on the reducer, and the output end of the reducer passes through the support frame and connects to the main shaft body. The main shaft provides support for the tire. When the motor is turned on, power is transmitted to the main shaft through the reducer, driving the tire on the main shaft to rotate. This controls the tire's spatial position, facilitating adjustment and processing, and improving the practicality of the device.

[0008] Preferably, the support device includes circular slots, limiting support rods, linear bearings, an inner support plate, and an annular airbag. Four sets of circular slots are evenly arranged on the front side of the main shaft, each containing a linear bearing. The four sets of limiting support rods are connected to the four sets of circular slots via the linear bearings. An inner support plate is connected to the outside of the limiting support rods. An annular airbag is positioned on the side of the inner support plate closest to the main shaft and is connected to the outer side of the main shaft. Inflating the annular airbag increases the internal air pressure, causing it to expand and push the inner support plate outwards. This provides fixed support for the tire's interior. The device effectively supports the tire, reducing localized deformation caused by excessive local pressure. The movement of the inner support plate is limited by circular slots, limiting support rods, and linear bearings, reducing vibration amplitude and improving stability. When the tire needs to be removed, the gas in the annular airbag is released, and the tire rotates with the drive mechanism. The tire's own weight then presses the four limiting support rods back into the circular slots, facilitating quick tire removal. The annular airbag provides support when the tire is subjected to external pressure; its deformable nature reduces tire damage, enhancing the device's practicality.

[0009] Preferably, it also includes a hexagonal limiting rod. A hexagonal limiting rod is installed at the bottom of the circular slot, and a hexagonal hole is provided on the lower end face of the limiting support rod corresponding to the hexagonal limiting rod. The hexagonal limiting rod is inserted into the limiting support rod. The limiting support rod is limited by the hexagonal limiting rod to prevent the limiting support rod from rotating during movement, which would cause the inner support plate to rotate and result in excessive local stress during tire fixing, thus improving the practicality of the device.

[0010] Preferably, it also includes an anti-detachment cover plate and connecting bolts. The anti-detachment cover plate is installed on the outer end face of the circular slot by the connecting bolts, and the limiting support rod passes through the middle of the anti-detachment cover plate. The linear bearing is fixed and limited by the anti-detachment cover plate and connecting bolts, which reduces the displacement of the linear bearing itself during operation and improves the stability of the device.

[0011] Preferably, it also includes a buffer pad, with a buffer pad placed on the underside of the linear bearing inside the circular slot; the buffer pad provides pressure buffering for the linear bearing during operation, increasing the service life of the linear bearing.

[0012] Preferably, the bottom support device includes an electric cylinder, a bottom support plate, and limiting rods. The electric cylinder is installed on the upper surface of the lower part of the frame, and the bottom support plate is installed on the moving end of the electric cylinder. Multiple sets of limiting rods are provided on the lower surface of the bottom support plate, and the multiple sets of limiting rods can be inserted into the lower part of the frame. By controlling the extension of the electric cylinder, the bottom support plate provides auxiliary support for the bottom of the tire, thereby reducing the deformation of the tire under its own weight. The multiple sets of limiting rods limit the lifting and lowering process of the bottom support plate, reducing the vibration amplitude of the bottom support plate during the lifting and lowering process, and improving the stability and practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the driving device provides power for the tire to rotate, which facilitates the tire to rotate and switch its own spatial position; the supporting device supports and fixes the inside of the tire, which increases the force-bearing area of ​​the tire support and fixation, and prevents the tire from deforming due to excessive local force; the bottom support device provides auxiliary support for the lower part of the tire, which improves the stability and practicality of the device.

Then, the motor 5 is turned on, and the power is transmitted to the main shaft 2 through the reducer 4, which drives the tire on the main shaft 2 to rotate, thereby controlling the tire to change its spatial position.

After the tire processing is completed, the gas in the annular airbag 10 is discharged, and the tire is rotated with the help of the drive device.

[0017] like Figures 1 to 4 As shown, this utility model discloses an aircraft tire forming blank fixing device. During operation, the tire blank is first mounted on multiple sets of inner support plates 9. Then, the internal air pressure of the annular airbag 10 is increased by inflating it, causing the annular airbag 10 to expand and push the inner support plates 9 outwards. This provides fixed support for the tire's interior, increasing the effective support area. Next, the motor 5 is activated, transmitting power through the reducer 4 to the main shaft 2, driving the tire on the main shaft 2 to rotate, thus controlling the tire's spatial position. Then, the electric cylinder 15 is extended, causing the bottom support plate 16 to provide auxiliary support for the tire's bottom.
