Description

Technical Field

[0001] The invention relates to the technical field of automobile tire repair, in particular to a laser grinding device for the inner wall of an automobile tire outer tread. Background Art

[0002] With the continuous development of the automotive industry and the increasing demand of consumers for tire quality, laser repair technology will be more widely used in the field of automobile tire manufacturing, especially in the production of high-end tires. Laser cleaning and polishing technology will become an important means to improve product quality and performance. At the same time, these technologies will also help reduce production costs, reduce environmental pollution and promote the sustainable development of the tire industry. In summary, the laser repair technology of the inner wall of automobile tires has broad application prospects and important economic value. With the continuous advancement of technology and further reduction of costs, it is believed that these technologies will be more widely promoted and applied in the future.

[0003] In the prior art, such as Chinese patent number: CN114654316A, there is provided a laser grinding device for the inner wall of the outer tire of an automobile tire, comprising a base, wherein the lower side wall of the base is symmetrically fixedly connected to a support column, the upper side wall of the base is symmetrically rotatably connected to a screw, the outer walls of the two screws are fixedly sleeved with pulleys, the outer walls of the two pulleys are jointly sleeved with a belt, and the outer walls of the two screws are threadedly connected to an ear plate located above the pulley. The present invention drives the screw to rotate by rotating a handle, drives the operating table and the tire to move up or down, thereby completing the adjustment of the tire height, making it more convenient to fix the tire, and the grinding plate 1 and the grinding plate 2 are respectively attached to the outer wall and the inner wall of the tire, and the tire is driven to rotate by the operating table, so that the outer wall and the inner wall of the tire rotate and rub against the grinding plate 1 and the grinding plate 2 respectively, thereby completing the grinding of the tire, which is simple to operate and has high grinding efficiency, thereby improving work efficiency.

[0004] Although the above patented equipment is easy to operate and has high grinding efficiency, thereby improving work efficiency, it still has many limitations when used, and taking the usage status as an example;

[0005] In the field of laser tire grinding, some laser devices have certain limitations in manufacturing, resulting in insufficient adjustment accuracy of the laser coverage width during the laser grinding process. This deficiency causes the laser beam to be unable to accurately match the actual needs of the tire inner wall during the grinding process, sometimes too wide, sometimes too narrow, which directly affects the final grinding effect. In addition, the laser coverage width adjustment capability of some laser devices is limited, making it difficult to adapt to the various sizes and types of tires on the market. This undoubtedly reduces the versatility and flexibility of the equipment. Some devices need to change positions twice or even multiple times for re-laser grinding, reducing the efficiency of the process. Some laser devices still need to rely on manual operation when adjusting the laser coverage width. This operation method not only increases the operating difficulty and workload of the operator, but also causes inaccurate adjustment due to human factors, which in turn affects the efficiency and accuracy of the grinding and affects subsequent use. Summary of the Invention

[0006] The object of the present invention is to provide a laser grinding device for the inner wall of a car tire casing to solve the problems raised in the above background.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a laser grinding device for the inner wall of a car tire outer shell, comprising: a driving mechanism, a limiting mechanism, an adjusting mechanism, and a grinding mechanism;

[0008] The driving mechanism is in contact with the ground, and its function is to increase the friction with the ground. It is used to maintain the effective rotation of the outer tire during use and can adjust its own rotation rate.

[0009] The limiting mechanism is used to maintain contact with both sides of the tire and can adjust its clamping width according to its own state;

[0010] A grinding mechanism is fixedly mounted on one side of the outer wall of the adjustment mechanism, which acts to adjust itself and can rotate the grinding mechanism to the inside of the outer tire;

[0011] The grinding mechanism is used to keep the high-energy laser beam focused by the first laser emitter irradiated on the inner surface of the tire, causing the material surface to heat up rapidly and undergo physical or chemical changes, thereby achieving laser grinding of the inner wall of the tire. The mechanism can also adjust the size, shape, position and other parameters of the laser coverage area through its own adjustment.

[0012] During tire inner wall grinding, two groups of second laser emitters and one group of first laser emitters are set up, controlled by three independent systems. Parameters such as laser power, focal length, and scanning speed are preset according to the tire material and degree of wear. After startup, the laser beam scans and grinds the tire inner wall evenly along the preset trajectory and speed. The system monitors the parameters in real time to ensure stability and consistency. In this way, the tire inner wall is smooth and flat after grinding, meeting quality requirements.

[0013] Preferably, the grinding mechanism includes a fan-shaped adjustment frame and two sets of adjustment shafts;

[0014] The outer wall of the fan-shaped adjustment frame is provided with a first drive groove, and a group of second drive grooves are preset inside the fan-shaped adjustment frame. A group of first laser emitters are provided on one side of the outer wall of the fan-shaped adjustment frame. Two engaging grooves are provided on one side of the outer wall of the fan-shaped adjustment frame. A first drive rod is rotatably connected between the inner walls of the first drive groove, and a transfer gear is fixedly sleeved on the outer wall of the first drive rod. The first drive groove and the second drive groove can provide support points for the rotation of the driven gear and the transfer gear respectively.

[0015] Preferably, a built-in motor is fixedly installed on the bottom of the inner wall of the fan-shaped adjustment frame, and the rotating end of the built-in motor is fixedly connected to a driving gear. The inner walls of the two sets of the second driving grooves are both driven to rotate and connected to a rotating rod. The outer walls of the two rotating rods are fixedly sleeved with a driven gear, and the outer wall of one of the two driven gears is meshed with the inner wall of the transfer gear for transmission, and the outer wall of the driving gear is meshed with the inner wall of the other of the two driven gears for transmission. The outer walls of the two rotating rods are fixedly sleeved with an adjusting column, and the outer walls of the two adjusting columns are fixedly installed with a group of slides. A group of annular moving grooves are preset inside the fan-shaped adjustment frame, and the outer walls of the two groups of slides are slidably embedded in the annular Inside the movable groove, the built-in motor can drive the driving gear fixed on its top to rotate when powered on. Because the driving gear and one of the two driven gears are meshed with each other, the other of the two driven gears is meshed with the driving gear using the intermediate gear as the transmission medium. Relying on this mutual transmission, when the driving gear rotates, and the two rotating rods can be rotated and connected to the second drive groove, the two adjusting columns are kept moving to both sides. During this movement, the two sets of slides can be slidably embedded in the annular movable groove to effectively limit this movement, thereby maintaining the stability of the two adjusting columns in the moving state.

[0016] Preferably, the rotating ends of the two groups of adjusting shafts are fixedly sleeved with adjusting plates, and one side of the inner walls of the two adjusting columns are fixedly installed with one side of the outer wall of one group of adjusting shafts, one side of the outer walls of the two groups of adjusting plates are fixed with automatic telescopic rods, and the outer walls of the two groups of automatic telescopic rods are movably sleeved with spring bodies, and the telescopic ends of the two groups of automatic telescopic rods are fixedly connected with fixed seats, and lateral adjusters are movably inserted into the interiors of the two fixed seats. The two groups of adjusting shafts and the two groups of lateral adjusters can form lateral position adjustment for the extension plate during its forward extension.

[0017] Preferably, one side of the outer wall of the two lateral adjusters is fixedly connected to an extension plate, the outer walls of the two extension plates are fixedly connected to a limiting block, and one side of the outer wall of the two extension plates is fixedly connected to a group of second laser emitters, the interior of the two adjusting columns is preset with an embedding groove, and the outer walls of the two groups of slides are slidably embedded in the embedding groove. When the two adjusting columns move to corresponding positions, the two groups of spring bodies inside generate elasticity themselves, and under the elasticity of the automatic telescopic rod itself, they can push the front end extension plate to move forward. In the process of the extension plate moving forward, the limiting block is slidably embedded in the embedding groove, thereby effectively limiting the external extension of the extension plate. In this way, the extension plate can be firmly engaged in the engaging groove, thereby keeping the two groups of second laser emitters and the group of first laser emitters in a ring surface flush state.

[0018] Preferably, the limit mechanism includes two vertical fixing plates, a limit rod is fixedly connected between opposite sides of the two vertical fixing plates, a bearing seat is fixedly inserted into the interior of the two vertical fixing plates, an adjusting rod is fixedly inserted between the inner surface walls of the two bearing seats, the outer wall of the adjusting rod is provided with two groups of threaded lines, one side of the outer wall of the adjusting rod is fixedly connected to an operating handle, two linkage plates are slidably embedded between the outer walls of the two limit rods, and the outer walls of the two groups of threaded lines are respectively threadedly transmitted in the interior of the linkage plate, one side of the outer wall of the two linkage plates is fixedly connected to a group of outer extension rods, the outer walls of the two groups of the outer extension rods are fixedly sleeved with a group of built-in bearings, and the outer surfaces of the two groups of built-in bearings A clamping roller is fixed between the walls, and the automobile tire body is placed between the outer walls of the two driving rotating rollers, and ensure that it is located between the opposite sides of the two sets of rotating rollers. Then, the operator holds the operating handle and rotates it. By rotating the operating handle, the adjusting rod is driven to rotate inside the two bearing seats. The two sets of symmetrical thread lines opened on the outside of the adjusting rod respectively generate threaded rotation with the inside of the two linkage plates. At the same time, the two linkage plates slide and limit on the outer walls of the two limit rods, so that the two linkage plates and the components fixed thereto can be threaded to move toward or away from each other. This adjustment method enables the two sets of clamping rollers to be in close contact with the outer wall of the automobile tire body, preparing for subsequent tire rotation.

[0019] Preferably, the adjustment mechanism includes two conveying main frames, and a side mounting plate is fixedly connected between one side of the outer wall of the two conveying main frames, and a self-locking motor is fixedly connected to one side of the outer wall of the side mounting plate, and a transmission box is fixedly installed on one side of the outer wall of the side mounting plate, and the rotating end of the self-locking motor is fixedly connected to the rotating end of the transmission box, and the rotating end of the transmission box is fixedly connected to a first gear, and the outer wall of the first gear is engaged with a second transmission chain. First, when the self-locking motor is powered on, its internal part keeps rotating, and when it is stopped, it can maintain a self-locking state under the mechanism set inside it, thereby maintaining the stability of the equipment when it is stopped.

[0020] Preferably, two bearing bodies are fixedly inserted within the side mounting plate, each of which has a second gear fixedly inserted within it. Multiple guide wheels are rotatably connected to the interiors of the side mounting plate and the two bearing bodies, and the outer walls of the second gears mesh with the interior of a second transmission chain. An annular transmission plate is rotatably connected between the outer walls of the multiple guide wheels, and one side of the outer wall of the annular transmission plate is fixedly connected to the outer wall of the fan-shaped adjustment frame. When the self-locking motor is energized, it drives the first gear at the rotating end of the drive transmission box to begin rotating. Simultaneously, the rotation of the first gear is linked to the first gear through the second gear and the second transmission chain tightly connected thereto. Multiple guide wheels are cleverly rotatably connected within the side mounting plate and the bearing bodies. Two of the guide wheels are directly fixedly connected to the outer wall of the second gear, allowing them to rotate synchronously with the rotation of the second gear. An annular transmission plate is movably connected between the outer walls of these guide wheels. When the guide wheels rotate with the rotation of the gears, they drive the annular transmission plate to rotate together through friction or a direct connection mechanism.

[0021] Preferably, the driving mechanism includes a driving bottom general frame plate, and the top of the driving bottom general frame plate is fixedly installed with the bottom of the two vertical fixed plates, and two groups of driving bearing bases are fixedly installed on the top of the driving bottom general frame plate, and a driving rotating roller is fixedly inserted between the inner surface walls of the two groups of driving bearing bases, and one side of the outer wall of the two driving rotating rollers is fixedly connected with a small transmission gear, and a first transmission chain is meshed and transmitted between the outer walls of the two small transmission gears. When the external driving motor is energized, one of the driving rotating rollers is driven to rotate inside a group of driving bearing bases. At the same time, the other driving rotating roller located on the other side is linked by two small transmission gears and a first transmission chain. When the two driving rotating rollers rotate synchronously, they can act together between the outer walls of the automobile tire body to achieve effective transmission of the tire, thereby making the automobile tire body rotate smoothly and continuously.

First, the driving base anti-slip cover is placed between the two transmission small gears and the outer walls of the first transmission chain, which can prevent external dust from interfering with its interior during the rotation process, thereby reducing the problem of meshing transmission efficiency.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

In the present invention, first, when the device is in use, the self-locking motor is started, causing the first gear at the rotating end of the transmission box to rotate, and the annular transmission plate is driven to rotate through a series of transmission mechanisms, so that the grinding mechanism can be suspended inside the tire, which provides convenience for subsequent laser grinding. In addition, the built-in motor drives the active gear to rotate, and through a complex gear transmission system, the two adjustment columns are extended outward, thereby adjusting the laser processing width of the grinding mechanism, achieving its precise adjustment, while improving processing efficiency and reducing labor costs. In addition, this adjustment ensures that the equipment can adapt to the grinding requirements of different tires and improves the adaptability of the device.

[0025] 2. In the present invention, after the external drive motor is energized, it drives the driven rotating roller to rotate. The two driven rotating rollers are linked through small transmission gears and transmission chains to ensure that the tire can rotate smoothly and continuously. At the same time, the two groups of rotating rollers are respectively fixed between the outer walls of the built-in bearings, which effectively limit the rotation of the tire, prevent the tire from shaking during the grinding process, and improve the grinding accuracy. The limiting mechanism can adjust the distance between the two groups of rotating rollers to improve the adaptability of the device to the tire.

[0026] 3. In the present invention, the device is precisely controlled by three independent control systems. Depending on the specific material and degree of wear of the tire's inner wall, corresponding parameters such as laser power, focal length, and scanning speed can be set in the control system. Under the guidance of the control system, the laser beam can scan and polish the tire's inner wall in a detailed and uniform manner according to the preset trajectory and speed, ensuring the stability and consistency of the polishing process.

[0052] In this embodiment, after the automobile tire body 15 is placed and processed, the self-locking motor 32 is started. When the self-locking motor 32 is powered on, an electromagnetic field is generated inside the self-locking motor 32, and the rotor rotates effectively inside such a magnetic field. The self-locking motor 32 transmits the rotational force generated by itself to the inside of the transmission box 321, thereby driving the first gear 322 fixedly installed at the rotating end of the transmission box 321 to rotate, and the second gear 332, the second transmission chain 333 and the first gear 322 are in a transmission state with each other, thereby maintaining the linkage of rotation between each other, and more on the other side.

First, when the built-in motor 43 is powered on, it can drive the driving gear 431 fixed on its top to rotate. Because the driving gear 431 and one of the two driven gears 441 are meshed with each other, the other of the two driven gears 441 is meshed with the driving gear 431 using the intermediate gear 421 as a transmission medium. Relying on this mutual transmission, when the driving gear 431 is rotating, and the two rotating rods 44 can be rotated and connected to the cooperation inside the second driving groove 412, the two adjusting columns 45 are kept moving to both sides. During this movement, the two sets of slides 45 1 can be slidably embedded in the annular movable groove 413 to effectively limit such movement, thereby maintaining the stability of the two adjustment columns 45 in the moving state. When the two adjustment columns 45 move to the corresponding positions, the two sets of spring bodies 463 inside generate elasticity themselves, and under the elasticity of the automatic telescopic rod 462 itself, the frontmost extension plate 48 can be pushed forward. During the forward movement of the extension plate 48, the limit block 481 is slidably embedded in the embedded groove 452, thereby effectively limiting the external extension of the extension plate 48. In this way, the extension plate 48 can be firmly engaged in the engaging groove 415, thereby maintaining the two sets of second laser emitters 482 and the one set of first laser emitters 414 in a ring-surface flush state.

[0054] Example 3, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 As shown, the driving mechanism 1 includes a driving bottom general frame plate 11, and the top of the driving bottom general frame plate 11 is fixedly installed with the bottom of two vertical fixed plates 21. Two sets of driving bearing bases 12 are fixedly installed on the top of the driving bottom general frame plate 11. A driving rotating roller 121 is fixedly inserted between the inner surface walls of the two sets of driving bearing bases 12. One side of the outer wall of the two driving rotating rollers 121 is fixedly connected to a small transmission gear 13. The outer walls of the two small transmission gears 13 are meshed with a first transmission chain 131 for transmission. The driving bottom general frame plate A driving base anti-slip cover 14 is fixedly installed on the top of 11, and two small transmission gears 13 and a first transmission chain 131 are arranged inside the driving base anti-slip cover 14. The outer walls of the two driving rotating rollers 121 are in contact with the automobile tire body 15. An external driving motor 16 is fixedly installed on the top of the driving bottom general frame plate 11, and the rotating end of the external driving motor 16 is fixedly connected to one side of the outer wall of one of the two driving rotating rollers 121, and the top of the driving bottom general frame plate 11 is fixedly connected to the bottom of the two conveying main frames 31;

[0055] The limiting mechanism 2 includes two vertical fixed plates 21, and a limiting rod 211 is fixedly connected between the opposite sides of the two vertical fixed plates 21. A bearing seat 22 is fixedly inserted into the interior of the two vertical fixed plates 21, and an adjusting rod 23 is fixedly inserted between the inner walls of the two bearing seats 22. The outer wall of the adjusting rod 23 is provided with two groups of threaded lines 231, and an operating handle 232 is fixedly connected to one side of the outer wall of the adjusting rod 23. Two linkage plates 24 are slidably embedded between the outer walls of the two limiting rods 211, and the outer walls of the two groups of threaded lines 231 are respectively threadedly transmitted in the interior of the linkage plate 24, and a group of outer extension rods 25 are fixedly connected to one side of the outer walls of the two linkage plates 24. The outer walls of the two groups of outer extension rods 25 are fixedly sleeved with a group of built-in bearings 251, and a clamping roller 26 is fixedly sleeved between the outer walls of the two groups of built-in bearings 251.

[0056] In this embodiment, when the device is in use, it is necessary to complete the preliminary adjustment of the device. First, the automobile tire body 15 is placed between the outer walls of the two driving rotating rollers 121, and the automobile tire body 15 is also kept between the two sets of clamping rollers 26. Then, the user holds the operating handle 232 and keeps the operating handle 232 rotating. Because the operating handle 232 and the adjusting rod 23 are in a fixed connection state, and the adjusting rod 23 itself rotates inside the two bearing seats 22, it provides good support for the rotation of the adjusting rod 23, and the two sets of thread lines 231 are provided on the outside. The two sets of threaded wires 231 rotate inside the two linkage plates 24 respectively. Since the directions of the two sets of threaded wires 231 are symmetrical, when the threaded wires 231 generate threaded rotation inside the two linkage plates 24, and the two linkage plates 24 are respectively limited and slid on the outer walls of the two limiting rods 211, the two linkage plates 24 and the components fixed thereto are pushed toward each other and away from each other. Through this adjustment method, the two sets of clamping rollers 26 are kept in contact with the outer walls of the automobile tire body 15, thereby effectively limiting the subsequent rotation of the automobile tire body 15.

[0057] Then start the equipment. When the external drive motor 16 is powered on, electromagnetic fields are generated inside it, and the rotor starts to rotate in this magnetic field, thereby driving one of the drive rotating rollers 121 to rotate inside a set of drive bearing bases 12. On the other side, the two drive rotating rollers 121 are linked through two small transmission gears 13 and a first transmission chain 131. When the two drive rotating rollers 121 rotate, effective transmission processing of the automobile tire body 15 is completed. When the automobile tire body 15 rotates, the two sets of clamping rollers 26 are respectively fixed between the outer walls of the built-in bearings 251, thereby effectively limiting the rotation of the automobile tire body 15.

[0058] The working principle of the entire mechanism is as follows: before use, the equipment needs to undergo a series of adjustments and treatments to ensure that it can efficiently and accurately complete the grinding process of the inner wall of the automobile tire;

[0059] First, place the automobile tire body 15 between the outer walls of the two driving rotating rollers 121 and ensure that it is located between the opposite sides of the two sets of clamping rollers 26. Then, the operator holds the operating handle 232 and rotates it. By rotating the operating handle 232, the adjusting rod 23 is driven to rotate inside the two bearing seats 22. The two sets of symmetrical thread lines 231 on the outside of the adjusting rod 23 respectively generate threaded rotation with the inside of the two linkage plates 24. At the same time, the two linkage plates 24 slide and limit on the outer walls of the two limiting rods 211, so that the two linkage plates 24 and the components fixed thereto can be threadedly pushed to move toward or away from each other. This adjustment method enables the two sets of clamping rollers 26 to be in close contact with the outer wall of the automobile tire body 15. To prepare for the subsequent tire rotation, the equipment is then started. The external drive motor 16 generates electromagnetic force after being energized. The internal electromagnetic drive rotor rotates and drives one of the drive rotating rollers 121 to rotate in the drive bearing base 12, while the drive rotating roller 121 on the other side is linked through two small transmission gears 13 and a first transmission chain 131. Through this mutual linkage, the car tire body 15 is driven to rotate. At the same time, the two sets of clamping rollers 26 are respectively fixed between the outer walls of the built-in bearing 251 to effectively limit the rotation of the tire and ensure the stability of the grinding process. After the tire is placed and starts to rotate, the self-locking motor 32 is started next. After being energized, the self-locking motor 32 generates electromagnetic force to drive the transmission box 321 to rotate. The first gear 322 at the end rotates, and maintains linkage with the first gear 322 through the transmission of the second gear 332 and the second transmission chain 333. At the same time, multiple guide wheels 331 are rotatably connected to the side mounting plate 311 and the inside of the bearing body 33, and two of the guide wheels 331 are fixedly connected to one side of the outer wall of the second gear 332. The annular transmission plate 34 rotates between the outer walls of the guide wheels 331, and the annular transmission plate 34 is driven to rotate by the transmission of the guide wheels 331. When the annular transmission plate 34 rotates 180 degrees, the grinding mechanism 4 is suspended inside the automobile tire body 15 to provide conditions for subsequent laser grinding. After the grinding mechanism 4 is placed inside the automobile tire body 15, it needs to be adjusted according to the grinding width of different tires. The built-in After the motor 43 is energized, it drives the driving gear 431 to rotate. The driving gear 431 meshes with one of the two driven gears 441 for transmission. The other driven gear 441 meshes with the driving gear 431 through the transfer gear 421. This transmission method enables the two rotating rods 44 to rotate inside the second driving groove 412, pushing the two adjusting columns 45 to move to both sides respectively. During the movement, the two sets of slides 451 are slidably embedded in the annular moving groove 413 to effectively limit the movement. When the adjusting column 45 moves to the corresponding position, the internal spring body 463 generates elasticity, pushing the automatic telescopic rod 462 to extend and retract, thereby pushing the extension plate 48 to move forward. In this process, the limit block 481 is slidably embedded in the embedded groove 452 with the cooperation.The extension plate 48 is positioned so that it can be securely engaged within the engagement groove 415, maintaining the two sets of second laser emitters 482 and the first laser emitter 414 flush with each other. During the tire inner wall grinding process, the three sets of laser emitters are precisely controlled by three independent control systems. Parameters such as laser power, focal length of the two laser emitters, and scanning speed are pre-set in the control systems based on the specific material and wear level of the tire inner wall. Once the control systems are activated, the laser emitters begin emitting laser beams. Under the precise guidance of the control system, these laser beams scan and grind the tire inner wall meticulously and evenly along the preset trajectory and speed. During the grinding process, the control system monitors key parameters such as laser beam power and focal length in real time to ensure stability and consistency of the grinding process. If any parameter deviations or changes are detected, the control system immediately adjusts to maintain laser beam accuracy and grinding results. This ensures that the tire inner wall presents a flat, smooth surface that meets quality requirements after grinding.
