Description

Technical Field

[0001] This invention relates to the field of aircraft tire retreading technology, and in particular to an aircraft tire reshaping device. Background Technology

[0002] Because aircraft tires are made of better materials than ordinary tires and have a shorter service life, an aircraft tire generally needs to be replaced after 150 to 180 takeoffs and landings. Moreover, aircraft tires are designed with retreading capabilities in mind. Furthermore, the environment in which aircraft tires are used is more singular than that of ordinary car tires, as they are only used on airport runways. Therefore, apart from the worn tread, the entire tire body of an aircraft tire is generally in good condition.

[0003] In summary, aircraft tire retreading is highly valuable and feasible. Aircraft tire retreading primarily involves replacing the worn tread. The process begins with reshaping the tire, removing the old rubber layer from the tread, and smoothing the outer surface. Then, a new tread layer is attached and vulcanized to complete the retreading process.

[0004] Existing devices for reshaping aircraft tires, such as those with patent applications "202220961246.5", "202222441964.2", and "200920155288.4", mainly consist of a clamping device and a grinding device, with the grinding device primarily being a grinding wheel. When applied to the aircraft tire retreading process, the old rubber layer on the entire tread of the aircraft tire needs to be removed. Due to the hardness of aircraft tires, relying solely on the grinding wheel to grind and reshape the outer surface of the aircraft tire is slow and inefficient, affecting the overall retreading progress and efficiency. Therefore, a tire reshaping device with high reshaping efficiency is needed to improve energy efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an aircraft tire shaping equipment with high shaping efficiency, fast speed, and reduced wear of the grinding device, which is also highly practical.

[0006] The aircraft tire refinishing equipment of the present invention includes a base plate, a bracket, and a support plate, with the support plate mounted on the upper part of the base plate via the bracket. It also includes a fixing device, a driving device, a cutting device, a grinding device, and a collecting device. The fixing device is mounted on the base plate and is used to fix the aircraft tire. The driving device is mounted on the fixing device and is used to drive the aircraft tire to rotate. The cutting device and the grinding device are both mounted on the support plate. The cutting device has a cutting function, the grinding device has a grinding function, and the collecting device has a debris collection function. When retreading an aircraft tire, the aircraft tire is first clamped and fixed by the fixing device. Then, the driving device is activated, causing the fixing device to rotate the aircraft tire. The cutting device removes most of the old rubber layer from the tire tread, and then the grinding device grinds the tread to remove the remaining old rubber layer. Simultaneously, a collection device collects the debris from the cutting and grinding process. After the tire is ground, an external retreading device secures it to the new tread layer. In the tire retreading process, the cutting device first removes most of the old rubber layer from the tire surface, followed by grinding and reshaping. Compared to existing single grinding methods, this method is more efficient, faster, and reduces wear on the grinding device, making it highly practical.

[0007] Preferably, the fixing device includes a support plate, a rotating shaft, and a wheel rim. The support plate is fixedly mounted on the base plate, the rotating shaft is rotatably mounted on the support plate, the wheel rim is fixedly mounted on the rotating shaft, and the drive device is mounted on the support plate. The output end of the drive device is connected to the rotating shaft. When fixing an aircraft tire, the aircraft tire is mounted on the wheel rim, and then the drive device is turned on to drive the rotating shaft to rotate. The rotating shaft drives the aircraft tire to rotate through the wheel rim. This facilitates the fixing and rotation of the aircraft tire.

[0008] Preferably, the drive device includes a fixed plate and a servo motor. The fixed plate is fixedly mounted on the support plate, and the servo motor is fixedly mounted on the fixed plate. The output end of the servo motor is connected to the rotating shaft, and the servo motor has an angle self-locking function. When rotating the aircraft tire, the servo motor is turned on, and the servo motor rotates the rim through the rotating shaft, which in turn drives the aircraft tire to rotate. This facilitates the rotation of the aircraft tire and improves convenience.

[0009] Preferably, the cutting device includes an electric slide rail A, a slider A, a vertical plate A, two sets of mounting plates A, a motor A, a rotating shaft, and multiple sets of cutting blades. The electric slide rail A is installed on the left side of the support plate, and the slider A is installed on the electric slide rail A. The electric slide rail A is used to move the slider A left and right. The vertical plate A is fixedly installed on the slider A. The two sets of mounting plates A are respectively fixedly installed on the front and rear parts of the vertical plate A. The motor A is fixedly installed on the mounting plate A. The rotating shaft is rotatably installed on the two sets of mounting plates A. The front end of the rotating shaft is connected to the output end of the motor A. Multiple sets of cutting blades are all fixedly installed on the rotating shaft. When cutting the rubber layer of an aircraft tire tread, first turn on motor A. Motor A drives multiple sets of cutting blades to rotate via a rotating shaft. Then, the electric slide rail A moves slider A to bring the upright plate A closer to the aircraft tire. The upright plate A, through two sets of mounting plates A, drives the rotating shaft to bring the multiple sets of cutting blades closer to the aircraft tire until the rotating multiple sets of cutting blades contact the aircraft tire, thus cutting the rubber layer of the aircraft tire tread. Since the multiple sets of cutting blades can move in the left and right directions, it can cut the tread of aircraft tires of different diameters, with low limitations and convenient use.

[0010] Preferably, the grinding device includes an electric slide rail B, a slider B, a vertical plate B, two sets of mounting plates B, a motor B, and a grinding wheel.

The electric slide rail B is used to move the slider B left and right. The vertical plate B is fixedly installed on the upper end of the slider B. The two sets of mounting plates B are respectively fixedly installed on the front and rear parts of the vertical plate B. The motor B is fixedly installed on the mounting plate B, and the grinding wheel is rotatably installed on the two sets of mounting plates B. The front end of the grinding wheel is connected to the motor B. When grinding the rubber layer of the aircraft tire tread, the motor B is turned on, and the motor B drives the grinding wheel to rotate. Then, the slider B is moved to the left through the electric slide rail B. The slider B, through the vertical plate B, drives the two sets of mounting plates B to move the grinding wheel to the left until the rotating grinding wheel contacts the aircraft tire, so that the rotating grinding wheel grinds the rubber layer on the surface of the aircraft tire. This improves convenience.

[0011] Preferably, the collection device includes a collection box, a sealing cover, and bolts. A slot is provided on the support plate, the collection box is placed on the base plate, and a cavity is provided inside the collection box.

Two sets of support rods are fixedly installed at the lower end of each of the two sets of guide plates. Both sets of guide plates are installed at an angle. The four sets of support rods are fixedly installed on the support plates via the four sets of base blocks. The lower ends of both sets of guide plates are located directly above the slot opening. Rubber debris polished from aircraft tires will fall onto the two sets of guide plates. Since two sets of guide plates are installed at an angle, the rubber debris falling onto the two sets of guide plates will slide down through the lower ends of the two sets of guide plates into the slot opening, and then fall into the collection box for collection. This facilitates the collection of rubber debris and improves convenience.

The electric turntable is fixedly mounted on the upper end of the support plate, the lower end of the robotic arm is mounted on the rotating end of the electric turntable, and the grinding device is mounted on the robotic arm. The robotic arm is used to move the grinding device, which has a grinding function. When repairing aircraft tires, if cracks are found on certain parts of the tire sidewall that need to be repaired, the grinding device can be moved to the area on the aircraft tire that needs to be repaired by the robotic arm. Then, the grinding device can grind the area on the aircraft tire that needs to be repaired until it is smooth, thus improving convenience.

[0014] Preferably, the grinding device includes a fixed block, a connecting frame, a drive motor, a rotating shaft, and a grinding wheel. The fixed block is fixedly mounted on the robotic arm, the connecting frame is fixedly mounted on the fixed block, the drive motor is fixedly mounted on the fixed block, the output end of the drive motor is connected to the rotating shaft, the rotating shaft is rotatably mounted on the connecting frame, and the grinding wheel is fixedly mounted on the rotating shaft.

Then, the drive motor is turned on, the drive motor drives the rotating shaft to rotate, and the rotating shaft drives the grinding wheel to rotate, allowing the rotating grinding wheel to grind the aircraft tire. This improves convenience.

[0015] Preferably, a protective cover is provided at the upper end of the support plate, and the protective cover is fixedly installed on the support plate; through the above arrangement, the debris splashed during the grinding of aircraft tires is prevented from hitting the workers, thus improving safety.
