Description

Technical Field

[0001] This invention belongs to the field of tire testing technology, specifically relating to a tire quality inspection organization and inspection method. Background Technology

[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, making contact with the road surface, and ensuring the vehicle's driving performance.

[0003] Tires are the carriers of force transmission between a vehicle and the road surface. They transmit driving force, braking force, and steering force, thereby enabling the vehicle to drive, brake, and steer. As the vehicle's mileage increases, the effectiveness of the tires in driving force, braking force, and steering force decreases. Therefore, to ensure tire safety, tires need to be inspected after a certain number of kilometers. The current tire inspection method involves removing the tire from the rim and then using an inspection agency for inspection. The tire is supported on the inspection agency, but because the agency only has a unidirectional fixing function, the inspection angle is limited, the tire's adjustment range is small, and the inspection efficiency is low. Summary of the Invention

The tire is supported on the quality inspection mechanism, but because the quality inspection mechanism only has a unidirectional fixing function, the inspection angle is limited, the tire's adjustment range is small, and the quality inspection efficiency is low.

[0006] (2) Technical solution

The illumination lamp is rotatably mounted on the support platform, the support mechanism corresponds to the illumination direction of the illumination lamp, and the fixing mechanism is provided inside the support platform.

[0008] The support mechanism includes a support frame, a telescopic tube, a fixed rod, a rotating cylinder, and a fixed cylinder. The rotating cylinder is rotatably mounted above the fixed cylinder. The fixed rods are symmetrically distributed on both sides of the rotating cylinder and are fixedly connected to the rotating cylinder. The support frame has an arc-shaped structure and is symmetrically distributed on both sides of the rotating cylinder. The telescopic tube is fixedly connected to the support frame, and the end of the telescopic tube away from the support frame is movably inserted into the fixed rod.

[0009] The fixing mechanism includes a force-bearing rod, a movable component, a drive rod, and a limiting head. The force-bearing rod has a U-shaped structure and slides into the interior of the support platform. The force-bearing rod is fixedly connected to the movable component. The movable component has an L-shaped structure and is symmetrically distributed in two sets. A drive rod is provided between the two sets of movable components. One end of the drive rod is fixedly connected to the movable component, and the other end is fixedly connected to the limiting head. A spring is connected to the movable component, and the end of the spring away from the movable component is fixedly connected to the interior of the support platform.

[0010] Furthermore, the interior of the rotating cylinder is hollow, and an adjusting rod is vertically inserted into the upper surface of the rotating cylinder. A drive gear is fixedly connected to one end of the adjusting rod that extends into the rotating cylinder, and two force-bearing gears are symmetrically distributed on the side of the drive gear.

[0011] Furthermore, both the force-bearing gear and the driving gear are conical. The force-bearing gear is located inside the rotating cylinder, and a threaded rod is fixedly connected to the center surface of the force-bearing gear. The threaded rod is rotatably disposed inside the fixed rod.

[0012] Furthermore, the telescopic tube has a threaded hole at one end that extends into the fixed rod, the threaded rod passes through the threaded hole and is threadedly connected to it, a movable block is welded to the upper surface of the telescopic tube, and a movable groove is horizontally opened on the upper surface of the fixed rod, the movable block passes through the movable groove and slides horizontally along it.

[0013] Furthermore, a rotating disk is threadedly connected to the bottom of the fixed cylinder, the rotating disk is threadedly connected to the fixed cylinder, a fixing block is fixedly protruding from the upper surface of the rotating disk, and a connecting rod is rotatably installed on the surface of the fixed cylinder facing the support platform, the connecting rod rotatably passing into the interior of the fixed cylinder.

[0014] Furthermore, one end of the connecting rod that penetrates into the fixed cylinder is fixedly connected to a connector, and the outer circumference of the connector is surrounded by multiple sets of fixing holes, which are inserted and fixed to the fixing block.

[0015] Furthermore, a connecting block is fixedly connected to the end of the connecting rod away from the fixed cylinder, a guide groove is horizontally opened on the support platform, the connecting block is embedded in the guide groove and slides horizontally, a moving rod is fixedly connected to the end of the connecting block facing the inside of the support platform, and a fixed tooth block is provided on the side of the moving rod away from the connecting block.

[0016] Furthermore, the fixed tooth block corresponds to the limiting head, and the limiting head has a movable tooth block on its surface facing the fixed tooth block.

[0017] A quality inspection method for a tire quality inspection agency includes the following steps:

[0018] S1. Rotate the fixed cylinder with the connecting rod as the support point so that the two sets of support frames are vertically distributed. Place the tire vertically outside the two sets of support frames. At this time, the outer wall of the tire is in contact with the upper surface of the support platform. Then rotate the adjusting rod. The adjusting rod drives the drive gear to rotate. The force-bearing gear meshing with the drive gear rotates accordingly. The threaded rod fixedly connected to the force-bearing gear rotates accordingly. The telescopic tube threadedly connected to the threaded rod is subjected to force and slides out along the inside of the fixed rod. Then the support frame is subjected to force and adheres to the inner wall of the tire to support the tire.

[0019] S2. After the tire is fixed, the illumination lamp can be turned on to irradiate the tire sidewall for quality inspection. During the quality inspection process, the tire is rotated by the rotating connection between the rotating cylinder and the fixed cylinder.

[0020] S3. As the quality inspection items are constantly changed, when it is necessary to rotate the tire in multiple directions, the force rod can be pushed by foot. The force rod moves inward toward the support platform, thereby driving the moving parts and drive rod to move synchronously. At this time, the spring is compressed, and the limit head drives the movable tooth block to leave the fixed tooth block. After losing the limit, the moving rod can move, thereby pushing the tire to move horizontally. After moving to the required position, the pressure on the force rod is released, the spring returns to its original position, and the limit head moves toward the moving rod again. The movable tooth block and the fixed tooth block fit together again to complete the fixation of the tire.

[0021] S4. The tire can also be fixed by rotating the connecting parts of the cylinder and the connecting rod in multiple directions. Rotate the rotating disk to make it gradually move away from the fixed cylinder, thereby driving the fixing block to descend. After the fixing block is removed from the inside of the fixing hole, the fixed cylinder can be rotated. After rotating to the required angle, push the rotating disk threaded into the fixed cylinder again. The fixing block is inserted into other fixing holes, so that the fixed cylinder is fixed and the tire is in an inclined state.

[0022] (3) Beneficial effects

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] This invention benefits from the cooperation of the fixing mechanism and the support mechanism, which allows for multi-range rotation and orientation adjustment of the tires to meet the inspection posture requirements of different quality inspection items. It also reduces the frequency of tire installation and removal, enabling a single tire installation to meet various quality inspection posture needs, making it highly practical. The force-bearing rod and the limiting head work together to limit the movement of the rod. The force-bearing rod can be pushed by the inspector's leg, making it easy to use. Furthermore, rotating the adjusting rod drives the telescopic tube to slide back and forth along the inner wall of the fixing rod, adapting to the fixing needs of tires of different sizes. The tire fixing process is simple, efficient, and meets quality inspection requirements. Attached Figure Description

A movable tooth block 24 is provided on the surface of the limiting head 23 facing the fixing tooth block 16. When the force-bearing rod 28 is subjected to force, it moves toward the inside of the support platform 4, thereby driving the moving part 27 and the drive rod 25 to move synchronously. At this time, the spring 26 is compressed, and the limiting head 23 drives the movable tooth block 24 to leave the fixed tooth block 16. After losing the limit, the moving rod 17 can move; otherwise, the moving rod 17 will be fixed.

[0036] Reference Figure 4The fixing mechanism 1 includes a force-bearing rod 28, a movable component 27, a drive rod 25, and a limiting head 23.

[0038] A quality inspection method for a tire quality inspection agency includes the following steps:

[0039] S1. Rotate the fixed cylinder 10 with the connecting rod 19 as the support point so that the two sets of support frames 6 are vertically distributed. Place the tire vertically outside the two sets of support frames 6. At this time, the outer wall of the tire is in contact with the upper surface of the support platform 4. Then rotate the adjusting rod 15. The adjusting rod 15 drives the drive gear 14 to rotate. The force-bearing gear 8 meshing with the drive gear 14 rotates accordingly. The threaded rod 12 fixedly connected to the force-bearing gear 8 rotates accordingly. The telescopic tube 7 threadedly connected to the threaded rod 12 is subjected to force and slides out along the inside of the fixed rod 13. Then the support frame 6 is subjected to force and adheres to the inner wall of the tire to support the tire.

[0040] S2. After the tire is fixed, the illumination lamp 3 can be turned on to irradiate the tire sidewall for quality inspection. During the quality inspection, the tire is rotated by the rotating cylinder 11 and the fixed cylinder 10.

[0041] S3. As the quality inspection items are constantly replaced, when it is necessary to rotate the tire in multiple directions, the force rod 28 can be pushed by foot. The force rod 28 moves towards the inside of the support platform 4 under force, thereby driving the moving part 27 and the drive rod 25 to move synchronously. At this time, the spring 26 is compressed, and the limit head 23 drives the movable tooth block 24 to leave the fixed tooth block 16. After losing the limit, the moving rod 17 can move, thereby pushing the tire to move horizontally. After moving to the required position, the pressure on the force rod 28 is released, the spring 26 returns to its original position, and the limit head 23 moves towards the moving rod 17 again. The movable tooth block 24 and the fixed tooth block 16 fit together again to complete the fixation of the tire.

[0042] S4. The tire can also be rotated in multiple directions by rotating the connecting part of the fixed cylinder 10 and the connecting rod 19. Rotate the rotating disk 9 to gradually move it away from the fixed cylinder 10, thereby driving the fixed block 22 to descend. After the fixed block 22 exits from the inside of the fixed hole 20, the fixed cylinder 10 can be rotated. After rotating to the required angle, push the rotating disk 9 back into the fixed cylinder 10 with the thread. The fixed block 22 is inserted into other fixed holes 20, so that the fixed cylinder 10 is fixed and the tire is in an inclined state.
