Description

Technical Field

[0001] This utility model relates to the field of tire production technology, specifically a tire wear resistance testing device. Background Technology

[0002] The Anruichi fourth-generation ULTRA coated self-healing safety tire features a three-dimensional interpenetrating network structure formed by the uniformly distributed short fiber reinforcement phase in the tread compound and the self-healing rubber layer after vulcanization. This allows the tire to have a self-sealing puncture function while still requiring precise evaluation of its wear resistance.

[0003] The existing tire wear resistance testing device consists of a fixed single-diameter drive roller, a rigid support roller, a cantilever loading arm, and a single-speed motor. During operation, the tire to be tested is placed on the drive roller, and a constant vertical load is applied through the cantilever loading arm. The motor drives the drive roller to rotate at a fixed speed, thereby simulating tire rolling wear.

[0004] Existing tire abrasion testing devices suffer from significant drawbacks during tire testing. They are incompatible with the testing requirements of different tire sizes, and the adjustment of position and angle during testing is extremely inconvenient. This results in a substantial reduction in testing efficiency and a significant decrease in the accuracy of test data, which seriously affects tire quality assessment and production optimization. Therefore, a tire abrasion testing device is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing tire abrasion testing devices mentioned in the background art, which are difficult to be compatible with the testing requirements of different tire specifications and are extremely inconvenient to adjust the position and angle during testing, resulting in a significant reduction in testing efficiency and a substantial decrease in the accuracy of testing data, seriously affecting tire quality assessment and production optimization, this utility model proposes a tire abrasion testing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A tire wear resistance testing device of this utility model includes a support frame. A bracket is fixedly installed on the upper part of one end of the support frame. A first motor and a second motor are fixedly installed on the same side of the upper end of the bracket. A convex shaft is rotatably installed inside the upper end of the bracket. The rotating shaft of the second motor is fixedly connected to one end of the convex shaft. Movable plates are provided on both sides of the bracket. Two through holes are opened at the upper end of each movable plate, and threaded grooves are opened in the upper through holes. A first gear is rotatably installed in the through holes of the movable plate. A sliding hole is opened in the center of the first gear, and a groove is opened on one side of the inner wall of the sliding hole. The first gear is slidably installed on both ends of the convex shaft. A rotating shaft is rotatably installed inside the lower end of each movable plate. Both ends of the rotating shaft penetrate the movable plate, and a second gear is fixedly installed at the outer end of each shaft. The second gear and the first gear rotate in cooperation via a synchronous belt. A first clamp is fixedly installed on opposite ends of the rotating shaft. The system consists of a first clamping plate and a second clamping plate. A support shaft is fixedly installed at the center of one side of the first clamping plate. Multiple positioning rods are arranged in an array around the outer periphery of the support shaft and fixedly installed on the first clamping plate. A top plate is slidably installed on the outside of the first clamping plate. The top plate has holes corresponding to the positions of the support shaft and positioning rods. A spring is fitted onto the support shaft between the first clamping plate and the top plate. A slot is provided on one side of the second clamping plate corresponding to the positions of the support shaft and positioning rods. A lifting plate is provided at the lower end of one end of the support frame. An adjustment box is fixedly installed at the center of the upper part of the lifting plate. A mounting seat is provided above the adjustment box. A mounting groove is provided on one side of the upper part of the mounting seat. A detection plate is slidably installed in the mounting groove. The bottom of the mounting seat is rotatably installed in the upper end of the adjustment box. Stable tire rotation is achieved through dual motors and gear transmission. The clamping plate and top plate cooperate to firmly fix the tire. The lifting plate and adjustment box can flexibly adjust the detection position angle, which can simulate the actual working conditions for comprehensive detection. The system is easy to operate and maintain, and can reduce labor and maintenance costs.

[0007] Preferably, a double-ended screw is rotatably mounted on the upper end of the support frame above the convex shaft. The upper ends of the movable plates are slidably mounted on both ends of the double-ended screw. A first motor is fixedly mounted on one side of the upper end of the support frame. The rotating shaft of the first motor is fixedly connected to one end of the double-ended screw. By driving the double-ended screw to rotate through the first motor, the movable plates on both sides can be moved synchronously towards or away from each other, thereby facilitating the adjustment of the distance between the first clamping plate and the second clamping plate to accommodate tires of different widths for clamping and fixing, improving the versatility and ease of operation of the device.

[0008] Preferably, a slide table is slidably installed on the upper end of the support frame. A hydraulic cylinder is fixedly installed on one side of the slide table and on the other end of the support frame. The hydraulic cylinder's hydraulic rod is fixedly connected to one side of the slide table. Slide grooves are provided on both sides of the upper part of the slide table. A bidirectional cylinder is fixedly installed in the center of the upper part of the slide table. A slide seat is fixedly connected to the piston rod of the bidirectional cylinder. Both ends of the bottom of the slide seat are slidably disposed in the slide groove. Support rollers are rotatably installed in the upper part of the slide seat. The horizontal movement position of the slide table on the support frame can be precisely controlled by the hydraulic cylinder, which facilitates the accurate movement of the tire to the detection position. By setting the bidirectional cylinder, the two slide seats can be driven to move synchronously towards or away from each other in the slide groove, thereby adjusting the distance between the two support rollers to accommodate tires of different diameters, providing stable and reliable support for the tire, and ensuring accurate clamping and fixing of the tire.

[0009] Preferably, electric cylinders are fixedly installed on both sides of the upper part of the support frame. The lead screws of the electric cylinders are respectively rotatably installed on the upper part of both ends of the lifting plate. By setting electric cylinders, the lifting height of the lifting plate can be precisely controlled, thereby conveniently adjusting the relative position between the detection plate and the tire to meet different detection requirements and tire specifications, making the detection process more flexible and accurate.

[0010] Preferably, the bottom of the mounting base is semi-circular, and worm gear grooves are evenly distributed on it. A worm gear is rotatably installed in the adjustment box below the mounting base. The worm gear meshes with the worm gear grooves at the bottom of the mounting base. A third motor is fixedly installed on one side of the adjustment box. The rotating shaft of the third motor is fixedly connected to one end of the worm gear. By driving the worm gear to rotate through the third motor, the angle of the mounting base can be precisely and stably adjusted by utilizing the self-locking characteristics of the worm gear transmission. This, in turn, drives the detection plate to contact the tire at different angles, thereby realizing the wear resistance test of different parts of the tire.

[0011] Preferably, the first motor, second motor, third motor, hydraulic cylinder, electric cylinder, and bidirectional pneumatic cylinder are all linearly connected to the PLC controller via power lines, and the PLC controller is used to control their start and stop. The PLC controller can accurately control parameters such as the speed and rotation angle of each motor and the extension and retraction of the electric cylinder, ensuring the stability and accuracy of the detection process.

[0012] The advantages of this utility model are: 1. This utility model, during tire inspection, involves activating a hydraulic cylinder to push a slide table within a support frame, moving the tire between a first clamping plate and a second clamping plate. A first motor then rotates a double-ended screw, which in turn moves a moving plate relative to the cam shaft along its axial direction, clamping and fixing the wheel hub. During clamping, the support shaft and positioning rod on the first clamping plate insert into corresponding slots on the second clamping plate. Simultaneously, a top plate, under the action of a spring, generates a certain preload on the tire and wheel hub, ensuring the tire is securely clamped. An electric cylinder then raises a lifting plate, which in turn raises the inspection plate, bringing it into contact with the bottom of the tire. A second motor then rotates the cam shaft, which in turn rotates the first gears at both ends. These first gears are connected via a synchronous belt. The second gear rotates, and through the shaft and clamping plate, it drives the tire to rotate. During the tire's rotation, the detection plate continuously contacts and rubs against the bottom of the tire, simulating the wear resistance of the tire in actual use. This structural design enables stable clamping and fixing of tires of different widths and diameters, precise positioning to the detection position, and flexible adjustment of the relative position and angle between the detection plate and the tire. It solves the problems of existing tire wear resistance testing devices, which are difficult to be compatible with the testing needs of different tire specifications and have extremely inconvenient position and angle adjustments during testing, resulting in a significant reduction in testing efficiency and a substantial decrease in the accuracy of testing data, seriously affecting tire quality assessment and production optimization. This improves the versatility of the testing device and the accuracy and flexibility of the testing process. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-5As shown, a tire abrasion resistance testing device includes a support frame 1. A bracket 2 is fixedly installed on the upper part of one end of the support frame 1. A first motor 5 and a second motor 7 are fixedly installed on the same side of the upper end of the bracket 2. A convex shaft 6 is rotatably installed inside the upper end of the bracket 2. The rotating shaft of the second motor 7 is fixedly connected to one end of the convex shaft 6. Movable plates 3 are provided on both sides of the bracket 2. Each movable plate 3 has two through holes at its upper end, and each through hole at the upper end has a threaded groove. A first gear 8 is rotatably installed in the through hole of the movable plate 3. A sliding hole is provided in the center of the first gear 8, and a groove is provided on one side of the inner wall of the sliding hole. The first gear 8 is slidably installed on both ends of the convex shaft 6. A rotating shaft 10 is rotatably installed inside the lower end of the movable plate 3. Both ends of the rotating shaft 10 pass through the movable plate 3, and a second gear 11 is fixedly installed on the outer end of each shaft. The second gear 11 and the first gear 8 rotate in cooperation through a synchronous belt 9. A first clamping plate 12 and a second clamping plate 13 are fixedly installed on one end of the support frame 1, respectively. A support shaft 14 is fixedly installed in the center of one side of the first clamping plate 12. Multiple positioning rods 15 are arranged in an array around the outer periphery of the support shaft 14 and fixedly installed on the first clamping plate 12. A top plate 16 is slidably installed on the outside of the first clamping plate 12. The top plate 16 has holes at the positions corresponding to the support shaft 14 and the positioning rods 15. A spring 17 is provided between the first clamping plate 12 and the top plate 16 and is fitted onto the support shaft 14. A slot is provided on one side of the second clamping plate 13 at the positions corresponding to the support shaft 14 and the positioning rods 15. A lifting plate 19 is provided below one end of the support frame 1. An adjustment box 20 is fixedly installed in the center of the upper part of the lifting plate 19. A mounting base 21 is provided above the adjustment box 20. A mounting groove is provided on one side of the upper part of the mounting base 21. A detection plate 22 is slidably installed in the mounting groove. The bottom of the mounting base 21 is rotatably installed in the upper part of the adjustment box 20.During operation, in the tire inspection process, the tire mounted on the wheel hub is placed on the upper part of the two support rollers 27 on the slide table 25. The hydraulic cylinder 29 is activated to push the slide table 25 to slide within the support frame 1, moving the tire between the first clamping plate 12 and the second clamping plate 13. The first motor 5 is activated to drive the double-headed screw 4 to rotate. The double-headed screw 4 drives the moving plate 3 to move relative to the cam shaft 6 in the axial direction, causing the clamping plate to clamp and fix the wheel hub. During the clamping process, the support shaft 14 and positioning rod 15 on the first clamping plate 12 will insert into the corresponding slots on the second clamping plate 13. At the same time, the top plate 16 will generate a certain preload on the tire and wheel hub under the action of the spring 17 to ensure that the tire is firmly clamped. Then, the hydraulic cylinder 29 is activated to retract, retracting the slide table 25. The electric cylinder 18 is activated to drive the lifting plate 19 to rise, and the lifting plate 19 drives the inspection plate 22 to rise, making it contact the bottom of the tire. The second motor 7 is started, driving the cam shaft 6 to rotate. The cam shaft 6 drives the first gears 8 at both ends to rotate. The first gears 8 drive the second gear 11 to rotate via the synchronous belt 9. The second gear 11 drives the tire to rotate via the rotating shaft 10 and the clamping plate. During the tire rotation, the detection plate 22 continuously contacts and rubs against the bottom of the tire, simulating the wear resistance of the tire in actual use, thereby realizing the tire wear resistance test. After the test is completed, the electric cylinder 18 is started, causing the lead screw of the electric cylinder 18 to rotate in the opposite direction, driving the lifting plate 19 to descend, thereby separating the detection plate 22 from the tire and lowering the detection plate 22 to the initial position. The first motor 5 is started, causing the double-headed screw 4 to rotate in the opposite direction, driving the moving plate 3 to move in the opposite direction, separating the first clamping plate 12 from the second clamping plate 13, releasing the clamp on the tire rim. Then the operator removes the tested tire from the testing device, and the entire tire wear resistance test process is completed.

[0018] A double-headed screw 4 is rotatably mounted on the upper end of the support frame 1 above the convex shaft 6. The upper end of the movable plate 3 is slidably mounted on both ends of the double-headed screw 4. A first motor 5 is fixedly mounted on one side of the upper end of the support frame 1. The rotating shaft of the first motor 5 is fixedly connected to one end of the double-headed screw 4. During operation, when the tire needs to be moved between the first clamping plate 12 and the second clamping plate 13 for clamping and fixing during tire inspection, the first motor 5 is started. Its rotating shaft drives the double-headed screw 4 to rotate, which causes the movable plate 3 to move relative to the double-headed screw 4 along the axial direction of the double-headed screw 4, so that the clamping plate connected to the movable plate 3 can accurately approach or move away from the tire hub. After the tire is clamped, the first motor 5 stops rotating, maintaining the stable clamping state of the clamping plate.

[0019] A slide table 25 is slidably installed on the upper end of the support frame 1. A hydraulic cylinder 29 is fixedly installed on one side of the slide table 25 and on the other end of the support frame 1. The hydraulic rod of the hydraulic cylinder 29 is fixedly connected to one side of the slide table 25. Slide grooves are opened on both sides of the upper part of the slide table 25. A bidirectional cylinder 28 is fixedly installed in the center of the upper part of the slide table 25. A slide seat 26 is fixedly connected to the piston rod of the bidirectional cylinder 28. The two ends of the bottom of the slide seat 26 are slidably disposed in the slide groove. A support roller 27 is rotatably installed in the upper part of the slide seat 26. During operation, before the tire inspection begins, the bidirectional cylinder 28 is activated according to the size of the tire rim. Its piston rod extends or retracts, causing the slide seat 26 to slide in the slide groove, thereby adjusting the distance between the two support rollers 27. After the tire is placed, the PLC controller activates the hydraulic cylinder 29. The hydraulic rod of the hydraulic cylinder 29 extends, pushing the slide table 25 to slide within the support frame 1, accurately moving the tire between the first clamping plate 12 and the second clamping plate 13. After the tire is clamped and fixed by the first clamping plate 12 and the second clamping plate 13, the hydraulic cylinder 29 is activated again, causing the hydraulic rod to retract and drive the slide table 25 out of the detection area.

[0020] Both sides of the bracket 2 are equipped with electric cylinders 18, which are fixedly installed on both sides of the upper part of the support frame 1. The lead screws of the electric cylinders 18 are respectively rotatably installed on the upper part of both ends of the lifting plate 19. During operation, in the tire inspection process, after the tire is clamped and fixed and the slide table 25 is retracted, when wear resistance testing is required, the electric cylinders 18 are activated. The lead screws of the electric cylinders 18 rotate, driving the lifting plate 19 to rise. The rise of the lifting plate 19 allows the detection plate 22 on the mounting base 21 to approach the bottom of the tire, providing height adjustment for the contact between the detection plate 22 and the tire and for wear resistance testing.

[0021] The bottom of the mounting base 21 is semi-circular, and worm gear grooves are evenly distributed on it. A worm gear 23 is rotatably installed in the adjustment box 20 below the mounting base 21. The worm gear 23 meshes with the worm gear grooves at the bottom of the mounting base 21. A third motor 24 is fixedly installed on one side of the adjustment box 20. The rotating shaft of the third motor 24 is fixedly connected to one end of the worm gear 23. During operation, when the lifting plate 19 moves the detection plate 22 close to the bottom of the tire during tire inspection, the third motor 24 is started. Its rotating shaft drives the worm gear 23 to rotate, which in turn drives the mounting base 21 to rotate through the worm gear grooves at the bottom of the mounting base 21, adjusting the angle of the detection plate 22. The detection plate 22 makes close and accurate contact with the bottom of the tire. When the angle of the detection plate 22 is adjusted to a suitable position, the third motor 24 stops rotating, maintaining the stable angle of the detection plate 22.

[0022] The first motor 5, the second motor 7, the third motor 24, the hydraulic cylinder 29, the electric cylinder 18, and the bidirectional cylinder 28 are all linearly connected to the PLC controller via power lines, and the PLC controller is used to control their start and stop. During operation, in the tire inspection process, the PLC controller precisely controls the start and stop and operating parameters of each component according to the preset program and inspection process. For example, it controls the first motor 5 and the double-headed screw 4 to realize the movement and clamping of the clamping plate, and controls the hydraulic cylinder 29 and the slide table 25 to realize the movement and positioning of the tire.

[0023] Working principle: During tire inspection, the tire mounted on the wheel hub is placed on the upper part of the two support rollers 27 on the slide table 25. The hydraulic cylinder 29 is activated to push the slide table 25 to slide within the support frame 1, moving the tire between the first clamping plate 12 and the second clamping plate 13. The first motor 5 is activated to drive the double-headed screw 4 to rotate, which in turn drives the moving plate 3 to move relative to the cam shaft 6 along the axial direction, causing the clamping plates to clamp and fix the wheel hub. During clamping, the support shaft 14 and positioning rod 15 on the first clamping plate 12 are inserted into the corresponding slots on the second clamping plate 13. At the same time, the top plate 16, under the action of the spring 17, generates a certain preload force on the tire and wheel hub to ensure that the tire is firmly clamped. Then, the hydraulic cylinder 29 is activated to retract, retracting the slide table 25. The electric cylinder 18 is activated to drive the lifting plate 19 to rise, which in turn drives the detection plate 22 to rise, bringing it into contact with the bottom of the tire. The second motor 7 is started, driving the cam shaft 6 to rotate. The cam shaft 6 drives the first gears 8 at both ends to rotate. The first gears 8 drive the second gear 11 to rotate via the synchronous belt 9. The second gear 11 drives the tire to rotate via the rotating shaft 10 and the clamping plate. During the tire rotation, the detection plate 22 continuously contacts and rubs against the bottom of the tire, simulating the wear resistance of the tire in actual use, thereby realizing the tire wear resistance test. After the test is completed, the electric cylinder 18 is started, causing the lead screw of the electric cylinder 18 to rotate in the opposite direction, driving the lifting plate 19 to descend, thereby separating the detection plate 22 from the tire and lowering the detection plate 22 to the initial position. The first motor 5 is started, causing the double-headed screw 4 to rotate in the opposite direction, driving the moving plate 3 to move in the opposite direction, separating the first clamping plate 12 from the second clamping plate 13, releasing the clamp on the tire rim. Then the operator takes the tested tire out of the testing device, and the entire tire wear resistance test process is completed.
