Description

Technical Field

[0001] This utility model belongs to the field of tire inspection technology, specifically a tire appearance inspection device. Background Technology

[0002] Tires are ring-shaped elastic components mounted on vehicle rims. They are mainly made of materials such as rubber and cord and can buffer road impacts, transmit driving and braking forces, and ensure the stability and safety of vehicle driving. They are suitable for different types of vehicles such as cars, trucks, and motorcycles.

[0003] Currently, operators frequently use inspection devices when performing visual inspections on tires after production. While existing inspection devices possess basic functions for inspecting the tire's outer surface, there is still room for improvement. Before inspection, operators must secure the tire using the device's clamping structure to prevent tire movement during inspection, which could cause the inspection lens to shift focus, miss surface defects, and thus affect inspection efficiency. However, the existing clamping components are fixed and can only accommodate tires of a single size. When inspecting tires of different diameters and widths, the existing clamping structure cannot flexibly adjust the spacing and clamping force. It either fails to clamp the tire stably or squeezes the tire tread due to excessive clamping, failing to meet the operator's needs for inspecting tires of multiple sizes. Frequent changes in inspection stations or adjustments to the device also extend the inspection cycle, causing inconvenience to the operator's work. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a tire appearance inspection device with the advantage of wide application range.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tire appearance inspection device, comprising a base, a box body movably connected to the left side of the top of the base, and clamping blocks movably connected to both the left and right sides of the top of the box body, the number of clamping blocks being two, the two clamping blocks being the same size, a servo motor being fixedly installed in the middle of the bottom of the inner surface of the box body, a rotating shaft being fixedly sleeved at the other end of the output shaft of the servo motor, a movable rod being fixedly sleeved above the outer surface of the rotating shaft, and two moving rods being hinged to both the left and right sides of the movable rod, the other end of the two moving rods being hinged to guide blocks, the number of guide blocks being two, the top ends of the two guide blocks passing through the box body and extending to the bottom ends of the two clamping blocks and being fixedly connected to the bottom ends of the two clamping blocks.

[0006] As a preferred embodiment of this utility model, a drive motor is fixedly installed on the left side inside the base, and a rotating shaft is fixedly sleeved on the other end of the output shaft of the drive motor. The top end of the rotating shaft extends to the bottom end of the box and is fixedly connected to the bottom end of the box. The outer surface of the rotating shaft is movably connected to the inside of the base.

[0007] As a preferred embodiment of this utility model, a connecting frame is fixedly connected to the right side of the top of the base, a moving block is movably connected to the left side of the connecting frame, and a limiting block located inside the top of the connecting frame is fixedly connected to the right side of the moving block. The outer surface of the limiting block is movably connected to the interior of the connecting frame.

[0008] As a preferred embodiment of this utility model, a hydraulic cylinder is fixedly installed at the top of the moving block, the bottom end of the hydraulic cylinder extends into the interior of the moving block and its outer surface is movably connected to the interior of the moving block, and a detection probe located at the bottom end of the moving block is fixedly connected to the bottom end of the hydraulic cylinder.

[0009] As a preferred embodiment of this utility model, a stepper motor is fixedly installed on the right side of the top of the connecting frame, and a round shaft is fixedly sleeved on the other end of the output shaft of the stepper motor.

[0010] As a preferred embodiment of this invention, a long rod is fixedly sleeved on the outer surface of the circular shaft, and a rotating rod is hinged to the other end of the long rod. The other end of the rotating rod is hinged to the right side of the top of the moving block.

[0011] As a preferred embodiment of this invention, the outer surfaces of both guide blocks are movably connected to the interior of the box, and both the outer surfaces of the two guide blocks and the interior of the box are smooth.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a servo motor, a rotating shaft, a movable rod, a moving rod, and guide blocks, allows the operator to start the servo motor, which drives the rotating shaft and the movable rod to rotate synchronously. The movable rod, through two moving rods, drives two guide blocks and two clamping blocks to move in opposite directions. This movement reduces the distance between the two clamping blocks, enabling the clamping blocks to stably clamp tires of different sizes, thus effectively expanding the application range of this detection device.

[0014] 2. This utility model, by setting up a stepper motor, a round shaft, a long rod, and a rotating rod, allows the operator to start the stepper motor, which drives the round shaft to rotate synchronously with the long rod. This rotation causes the rotating rod to push the moving block to move to the left, thereby allowing the detection probe to move precisely above the center of the tire. Subsequently, the operator activates the hydraulic cylinder, which allows the detection probe to extend downward into the tire. This operation allows the detection probe to complete the detection of both the inner and outer surfaces of the tire in one operation, ultimately providing significant convenience for the operator's actual use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a tire appearance inspection device, including a base 1, a box 2 movably connected to the left side of the top of the base 1, and clamping blocks 3 movably connected to the left and right sides of the top of the box 2. There are two clamping blocks 3, and the two clamping blocks 3 are the same size. A servo motor 4 is fixedly installed in the middle of the bottom of the inner surface of the box 2. A rotating shaft 5 is fixedly sleeved at the other end of the output shaft of the servo motor 4. A movable rod 6 is fixedly sleeved on the upper part of the outer surface of the rotating shaft 5. Motion rods 7 are hinged to the left and right sides of the movable rod 6. There are two motion rods 7. Guide blocks 8 are hinged to the other end of the two motion rods 7. There are two guide blocks 8. The top of the two guide blocks 8 passes through the box 2 and extends to the bottom of the two clamping blocks 3 and is fixedly connected to the bottom of the two clamping blocks 3.

[0023] When the operator starts the servo motor 4, the rotating shaft 5 and the movable rod 6 will rotate. This will cause the movable rod 6 to drive the two guide blocks 8 to move in opposite directions through the two moving rods 7, so that the two clamping blocks 3 can clamp tires of different sizes.

[0024] The base 1 has a drive motor 9 fixedly installed on the left side inside. The other end of the output shaft of the drive motor 9 is fixedly sleeved with a rotating shaft 10. The top end of the rotating shaft 10 extends to the bottom end of the box 2 and is fixedly connected to the bottom end of the box 2. The outer surface of the rotating shaft 10 is movably connected to the inside of the base 1.

[0025] When the operator starts the drive motor 9, the rotating shaft 10 will cause the entire box 2 to rotate together.

[0026] The base 1 has a connecting frame 11 fixedly connected to the right side of the top end, a moving block 12 movably connected to the left side of the connecting frame 11, and a limiting block 19 located inside the top end of the connecting frame 11 fixedly connected to the right side of the moving block 12. The outer surface of the limiting block 19 is movably connected to the interior of the connecting frame 11.

[0027] Due to the design of the limiting block 19, it can effectively guide the subsequent movement of the moving block 12.

[0028] A hydraulic cylinder 13 is fixedly installed at the top of the moving block 12. The bottom end of the hydraulic cylinder 13 extends into the interior of the moving block 12 and its outer surface is movably connected to the interior of the moving block 12. A detection probe 14 located at the bottom of the moving block 12 is fixedly connected to the bottom end of the hydraulic cylinder 13.

[0029] When the operator operates the hydraulic cylinder 13, the detection probe 14 will move downwards as a whole. As existing technology, the detection probe 14 has the function of detecting whether the tire is damaged, so it will not be described in detail here.

[0030] A stepper motor 15 is fixedly installed on the right side of the top of the connecting frame 11, and a round shaft 16 is fixedly sleeved on the other end of the output shaft of the stepper motor 15.

[0031] When the operator starts the stepper motor 15, the circular shaft 16 will rotate.

[0032] Among them, a long rod 17 is fixedly sleeved on the outer surface of the round shaft 16, and a rotating rod 18 is hinged to the other end of the long rod 17. The other end of the rotating rod 18 is hinged to the right side of the top of the moving block 12.

[0033] When the circular shaft 16 rotates, it will cause the long rod 17 to rotate as well.

[0034] The outer surfaces of the two guide blocks 8 are movably connected to the interior of the box 2, and both the outer surfaces of the two guide blocks 8 and the interior of the box 2 are smooth.

[0035] Since the outer surfaces of the two guide blocks 8 and the interior of the box 2 are both smooth, the two guide blocks 8 can move more smoothly inside the box 2.

[0036] Working principle and usage process of this utility model:

[0037] First, the operator places the tire between the two clamping blocks 3. Then, the operator starts the servo motor 4, which will cause the rotating shaft 5 and the movable rod 6 to rotate. This causes the movable rod 6 to drive the two guide blocks 8 and the two clamping blocks 3 to move in opposite directions through the two moving rods 7. This causes the two clamping blocks 3 to clamp the tire. After clamping, the operator starts the drive motor 9, which will cause the rotating shaft 10 to drive the entire box 2 to rotate.

[0038] Finally, the operator operates the hydraulic cylinder 13, which causes the detection probe 14 to move downwards, allowing the detection probe 14 to perform inspection work on the outer surface of the tire. After the outer surface inspection is completed, the operator operates the hydraulic cylinder 13 again, causing the detection probe 14 to move upwards. At this time, the operator operates the stepper motor 15 and the hydraulic cylinder 13. The operation of the stepper motor 15 causes the circular shaft 16 and the long rod 17 to rotate, which causes the rotating rod 18 to push the moving block 12 to move to the left, so that the detection probe 14 will move above the center of the tire. The operation of the hydraulic cylinder 13 will cause the detection probe 14 to move downwards into the inside of the tire, so that the detection probe 14 can also perform inspection work on the inner surface of the tire.
