Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire trimming, and in particular to an aircraft tire tread edge trimming device. Background Technology

[0002] During the vulcanization process of aircraft tires, the junction between the tread rubber and sidewall rubber may produce excess rubber edges, flash, or irregular protrusions due to issues such as mold precision and uneven rubber flow. These residues can lead to uneven clearances between the tire and components such as the rim and brake system after installation, causing localized friction and vibration during high-speed rotation or landing impacts, thus affecting landing safety. Therefore, it is necessary to use a trimming device to remove excess rubber and flash from aircraft tires. In the prior art, a utility model patent with patent application number 202420349929.4 discloses an aircraft tire edge grinding device, which mainly consists of a grinding block and a rim. In use, the aircraft tire is fixed by the rim, and then the grinding block grinds the aircraft tire. However, it has the following problems in use: it can only grind the curved tread of the aircraft tire and cannot grind the sidewall, making it inconvenient to use and highly limited in its application. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an aircraft tire tread edge trimming device that can not only grind the arc-shaped tread of aircraft tires, but also grind the sidewall of aircraft tires, resulting in better trimming effect, convenient use, and high practicality.

[0004] This utility model discloses an aircraft tire tread edge trimming device, comprising a base plate; it also includes a lifting mechanism, a clamping mechanism, an arc surface grinding mechanism, and a sidewall grinding mechanism. The clamping mechanism is mounted on the base plate via the lifting mechanism, which is used to raise and lower the clamping mechanism. The arc surface grinding mechanism is mounted on the base plate, and the sidewall grinding mechanism is located above the arc surface grinding mechanism. When trimming the burrs on the surface of an aircraft tire, the aircraft tire is first clamped and fixed by the clamping mechanism. Then, the lifting mechanism lowers the aircraft tire to contact the arc surface grinding mechanism. The arc surface grinding mechanism then grinds and trims the arc surface of the aircraft tire. Afterward, the aircraft tire is raised to contact the sidewall grinding mechanism, which then grinds the sidewall of the aircraft tire. This device can not only grind the arc-shaped tread of aircraft tires but also grind the sidewalls, resulting in better trimming effects, ease of use, and high practicality.

[0005] Preferably, the lifting mechanism includes a hydraulic cylinder, a lifting rod, a fixed column, a sliding column, and a lifting plate. The hydraulic cylinder is fixedly installed on the upper end of the base plate. The lower end of the lifting rod is connected to the power output end of the hydraulic cylinder. The fixed column is fixedly installed on the upper end of the base plate. The lower part of the sliding column is slidably installed on the fixed column. The lifting plate is fixedly installed on the upper ends of the sliding column and the lifting rod. The clamping mechanism is installed on the upper end of the lifting plate. When grinding and trimming aircraft tires, if the height of the aircraft tire needs to be adjusted, the hydraulic cylinder is opened. The hydraulic cylinder adjusts the height of the lifting plate through the lifting rod, which in turn causes the clamping mechanism to adjust the height of the aircraft tire, thus facilitating the adjustment of the aircraft tire height.

[0006] Preferably, the clamping mechanism includes an indexing plate A, a three-jaw chuck, a rotating shaft, and a wheel hub. The indexing plate A is fixedly installed on the upper end of the lifting plate, the three-jaw chuck is fixedly installed on the rotating end of the left side of the indexing plate A, the right end of the rotating shaft is clamped and fixed by the three-jaw chuck, and the wheel hub is fixedly installed on the left side of the rotating shaft. When fixing the aircraft tire, the aircraft tire is installed and fixed on the wheel hub. When grinding and finishing the aircraft tire, the indexing plate A can be opened, the indexing plate A drives the three-jaw chuck to rotate, the three-jaw chuck drives the rotating shaft and the wheel hub to rotate, thereby causing the aircraft tire to rotate. This allows all parts of the aircraft tire in the circumferential direction to be ground, facilitating the grinding and finishing of the aircraft tire.

[0007] Preferably, the arc surface grinding mechanism includes a bracket, a motor, a drive shaft, a mounting base, and a grinding wheel. The bracket is fixedly mounted on the base plate, the motor is fixedly mounted on the base plate, and the power output end of the motor is provided with a drive shaft. The drive shaft is rotatably mounted on the mounting base, the grinding wheel is fixedly mounted on the drive shaft, and the mounting base is fixedly mounted on the bracket. The grinding wheel is located below the wheel hub. When it is necessary to grind the arc surface of the aircraft tire, the motor is turned on, and the motor causes the grinding wheel to rotate rapidly through the drive shaft. Then, the three-jaw chuck is opened, and the three-jaw chuck causes the wheel hub to rotate through the rotating shaft, causing the parts with protrusions or burrs on the arc surface of the aircraft tire to rotate to the side facing the grinding wheel. Then, the aircraft tire is lowered, so that the burrs and flash on the aircraft tire come into contact with the rotating grinding wheel. The rotating grinding wheel grinds away the burrs and flash on the arc surface of the aircraft tire, which facilitates the grinding of the arc surface of the aircraft tire.

[0008] Preferably, the sidewall polishing mechanism includes a moving mechanism and a polishing machine. The polishing machine is mounted on the moving mechanism, which is used to move the polishing machine. The polishing machine is equipped with a polishing disc. When polishing the sidewall of an aircraft tire, firstly, one sidewall of the aircraft tire is brought towards the polishing disc. Then, the part of the aircraft tire sidewall with burrs is rotated to face the polishing disc. Then, the polishing machine is turned on, and the polishing machine drives the polishing disc to rotate. Then, the moving mechanism drives the polishing machine to move the polishing disc towards the sidewall of the aircraft tire. Finally, the rotating polishing disc polishes away the burrs on the aircraft tire.

[0009] Preferably, the moving mechanism includes a linear module, a sliding plate, and a rotating mechanism. A support frame is mounted on the linear module, which is then installed on a base plate via the support frame. A sliding plate is also mounted on the linear module, allowing it to move left and right. The rotating mechanism is installed at the lower end of the sliding plate, and a grinder is mounted on the rotating mechanism. When grinding the sidewall of an aircraft tire, the grinder is turned on, causing the grinding disc to rotate. Then, the linear module is turned on, and the sliding plate causes the rotating mechanism and the grinder to move towards the sidewall of the aircraft tire, bringing the grinding disc on the grinder to contact the burrs on the aircraft tire. The grinding disc then grinds the burrs on the aircraft tire.

[0010] Preferably, the rotating mechanism includes an indexing plate B and a rotating shaft. The indexing plate B is fixedly installed at the lower end of the sliding plate, and the rotating shaft is installed at the rotating end of the lower part of the indexing plate B. The grinding machine is fixedly installed at the lower end of the rotating shaft. Both the indexing plate B and the indexing plate A have an angle self-locking function. When grinding the left side tread of the aircraft tire, the grinding machine is positioned on the left side of the aircraft tire, and the grinding disc is directed towards the aircraft tire. Then, the grinding disc is moved to contact the left side tread of the aircraft tire, allowing the grinding disc to grind the left side tread of the aircraft tire. When grinding the right tread of an empty tire, first lower the aircraft tire, then open the linear module to move the sliding plate, indexing plate B, rotating shaft, and grinding machine to the right side of the aircraft tire. Then open indexing plate B to rotate the rotating shaft and make the grinding disc on the grinding machine rotate to face the side of the aircraft tire. Then raise the aircraft tire to move the right tread of the aircraft tire to the left side of the grinding disc. Then grind the right tread of the aircraft tire through the grinding disc. This facilitates the grinding and finishing of the two treads on the aircraft tire.

[0011] Preferably, the base plate is equipped with a lighting lamp; this arrangement makes the area above the base plate brighter, facilitating monitoring of the grinding and finishing process.

[0012] Compared with the prior art, the advantages of this utility model are: it can not only grind the arc-shaped tread of aircraft tires, but also grind the sidewall of aircraft tires, resulting in better finishing effect of aircraft tires, convenient use, and high practicality.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. 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.

[0020] Example 1

[0021] like Figures 1 to 5 The present invention relates to an aircraft tire tread edge trimming device, comprising a base plate 1, a lifting mechanism, a clamping mechanism, an arc surface grinding mechanism, and a sidewall grinding mechanism. The clamping mechanism is mounted on the base plate 1 via the lifting mechanism, which is used to raise and lower the clamping mechanism. The arc surface grinding mechanism is mounted on the base plate 1, and the sidewall grinding mechanism is located above the arc surface grinding mechanism. When trimming the burrs on the surface of the aircraft tire 22, the aircraft tire 22 is first clamped and fixed by the clamping mechanism. Then, the lifting mechanism lowers the aircraft tire 22 to contact the arc surface grinding mechanism. The arc surface grinding mechanism then grinds and trims the arc surface of the aircraft tire 22. Afterward, the aircraft tire 22 is raised to contact the sidewall grinding mechanism, which then grinds the sidewall of the aircraft tire 22. This device can grind not only the arc-shaped tread of the aircraft tire 22 but also the sidewall, resulting in better trimming effect, ease of use, and high practicality.

[0022] like Figure 1 and Figure 3The lifting mechanism includes a hydraulic cylinder 2, a lifting rod 3, a fixed column 4, a sliding column 5, and a lifting plate 6. The hydraulic cylinder 2 is fixedly installed on the upper end of the base plate 1. The lower end of the lifting rod 3 is connected to the power output end of the hydraulic cylinder 2. The fixed column 4 is fixedly installed on the upper end of the base plate 1. The lower part of the sliding column 5 is slidably installed on the fixed column 4. The lifting plate 6 is fixedly installed on the upper ends of the sliding column 5 and the lifting rod 3. The clamping mechanism is installed on the upper end of the lifting plate 6. When grinding and trimming the aircraft tire 22, if it is necessary to adjust the height of the aircraft tire 22, the hydraulic cylinder 2 is opened. The hydraulic cylinder 2 adjusts the height of the lifting plate 6 through the lifting rod 3, which in turn causes the clamping mechanism to drive the aircraft tire 22 to adjust its height, thus facilitating the adjustment of the height of the aircraft tire 22.

[0023] like Figure 3 The clamping mechanism includes an indexing plate A7, a three-jaw chuck 8, a rotating shaft 9, and a wheel hub 10. The indexing plate A7 is fixedly installed on the upper end of the lifting plate 6. The three-jaw chuck 8 is fixedly installed on the rotating end of the left side of the indexing plate A7. The right end of the rotating shaft 9 is clamped and fixed by the three-jaw chuck 8. The wheel hub 10 is fixedly installed on the left side of the rotating shaft 9. When fixing the aircraft tire 22, the aircraft tire 22 is fixedly installed on the wheel hub 10. When grinding and trimming the aircraft tire 22, the indexing plate A7 can be opened. The indexing plate A7 drives the three-jaw chuck 8 to rotate. The three-jaw chuck 8 drives the rotating shaft 9 and the wheel hub 10 to rotate, thereby causing the aircraft tire 22 to rotate. This allows all parts of the aircraft tire 22 in the circumferential direction to be ground, which facilitates the grinding and trimming of the aircraft tire 22.

[0024] like Figure 1 and Figure 4 The arc surface grinding mechanism includes a bracket 11, a motor 12, a drive shaft 13, a mounting base 14, and a grinding wheel 15. The bracket 11 is fixedly mounted on the base plate 1, and the motor 12 is fixedly mounted on the base plate 1. The power output end of the motor 12 is provided with the drive shaft 13, which is rotatably mounted on the mounting base 14. The grinding wheel 15 is fixedly mounted on the drive shaft 13, and the mounting base 14 is fixedly mounted on the bracket 11. The grinding wheel 15 is located below the wheel hub 10. When it is necessary to grind the arc surface of the aircraft tire 22, the motor 12 is turned on. Machine 12 drives the grinding wheel 15 to rotate rapidly via drive shaft 13. Then, the three-jaw chuck 8 is opened. The three-jaw chuck 8 drives the hub 10 to rotate via shaft 9. This causes the parts of the aircraft tire 22 with protrusions or burrs on the arc surface to rotate to the side facing the grinding wheel 15. Then, the aircraft tire 22 is lowered so that the burrs and flash on the aircraft tire 22 come into contact with the rotating grinding wheel 15. The rotating grinding wheel 15 grinds away the burrs and flash on the arc surface of the aircraft tire 22, which facilitates the grinding of the arc surface of the aircraft tire 22.

[0025] like Figure 1 and Figure 5The sidewall polishing mechanism includes a moving mechanism and a polishing machine 16. The polishing machine 16 is mounted on the moving mechanism, which is used to move the polishing machine 16. A polishing disc 17 is provided on the polishing machine 16. When polishing the sidewall of the aircraft tire 22, firstly, one sidewall of the aircraft tire 22 is brought towards the polishing disc 17. Then, the part of the sidewall of the aircraft tire 22 with burrs is rotated to face the polishing disc 17. Then, the polishing machine 16 is turned on, and the polishing machine 16 drives the polishing disc 17 to rotate. Then, the moving mechanism causes the polishing machine 16 to move the polishing disc 17 towards the sidewall of the aircraft tire 22. Then, the rotating polishing disc 17 polishes away the burrs on the aircraft tire 22.

[0026] like Figure 1 and Figure 5 The moving mechanism includes a linear module 18, a sliding plate 19, and a rotating mechanism. A support frame is mounted on the linear module 18, which is installed on the base plate 1 via the support frame. The sliding plate 19 is used to move the linear module 18 left and right. The rotating mechanism is installed at the lower end of the sliding plate 19, and the grinding machine 16 is installed on the rotating mechanism. When grinding the sidewall of the aircraft tire 22, the grinding machine 16 is turned on, causing the grinding disc 17 to rotate. Then, the linear module 18 is turned on, and the sliding plate 19 causes the rotating mechanism and the grinding machine 16 to move towards the sidewall of the aircraft tire 22, moving the grinding disc 17 on the grinding machine 16 until it contacts the burrs on the aircraft tire 22. The grinding disc 17 then grinds the burrs on the aircraft tire 22.

[0027] like Figure 1The rotating mechanism includes an indexing plate B20 and a rotating shaft 21. The indexing plate B20 is fixedly installed at the lower end of the sliding plate 19, and the rotating shaft 21 is installed at the rotating end of the lower part of the indexing plate B20. The grinding machine 16 is fixedly installed at the lower end of the rotating shaft 21. Both the indexing plate B20 and the indexing plate A7 have an angle self-locking function. When grinding the left side tread of the aircraft tire 22, the grinding machine 16 is positioned on the left side of the aircraft tire 22, and the grinding disc 17 is brought towards the aircraft tire 22. Then, the grinding disc 17 is moved to contact the left side tread of the aircraft tire 22, so that the grinding disc 17 grinds the left side tread of the aircraft tire 22. When grinding the aircraft tire 2... 2. When grinding the right side tread, first lower the aircraft tire 22, then open the linear module 18, causing the sliding plate 19, indexing plate B20, rotating shaft 21, and grinding machine 16 to move to the right side of the aircraft tire 22. Then open the indexing plate B20, causing the rotating shaft 21 to drive the grinding machine 16 to rotate, causing the grinding disc 17 on the grinding machine 16 to rotate to the side facing the aircraft tire 22. Then raise the aircraft tire 22, causing the right side tread of the aircraft tire 22 to move to the left side of the grinding disc 17. Then grind the right side tread of the aircraft tire 22 through the grinding disc 17. This facilitates the grinding and finishing of the two treads on the aircraft tire 22.
