Description

Technical Field

[0001] This utility model relates to the field of rubber-coated wheel thickness measurement technology, specifically to an ultrasonic thickness measurement device for rubber-coated wheels. Background Technology

[0002] Ultrasonic thickness gauges for rubber-coated wheels are specialized instruments used to measure the thickness of the rubber layer on rubber-coated wheels (such as rubber-coated metal wheels), and are typically based on ultrasonic measurement technology.

[0003] If the rubber-coated wheel cannot be fixed, it will cause the wheel's position to shift or become unstable during the measurement process, thus affecting the transmission and reflection of ultrasonic signals and resulting in inaccurate measurement results.

[0004] Secondly, if the rubber-coated wheel does not rotate, it may only be possible to measure at a single location. This makes it impossible to determine whether the rubber layer thickness of the entire wheel is uniform, and it is easy to overlook abnormalities in certain locations.

[0005] Finally, if the lateral position of the measuring instrument cannot be adjusted, it may not be able to adapt to rubber-coated wheels of different sizes, causing the probe to be unable to measure in the appropriate position and affecting the accuracy of the measurement results.

[0026] 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. Example

[0027] Please see Figures 1-5An ultrasonic thickness measuring device for rubber-coated wheels includes a main body 1, a clamping mechanism, a rotating assembly, and a sliding mechanism. The clamping mechanism includes a first motor 2, a rotating rod 3, a lifting plate 4, a connecting rod 5, and a locking block 6. The rotating rod 3 is fixedly connected to the output end of the first motor 2. The lifting plate 4 is mounted on the rotating rod 3 and is connected to the rotating rod 3. One end of the connecting rod 5 is rotatably connected to the lifting plate 4, and the other end is rotatably connected to the locking block 6. The rotating assembly includes a placement frame 7, a second motor 8, a drive gear 9, and a first roller 10. The placement frame 7 is mounted on the main body 1 and is rotatably connected to the main body 1. The first motor 2 is fixedly mounted on the bottom of the placement frame 7. The locking block 6 is mounted on the placement frame 7 and is slidably connected to the placement frame 7. The second motor 8 is fixedly mounted on the bottom of the main body 1. The drive gear 9 is fixedly mounted on the output end of the second motor 8. The first roller 10 is mounted on the placement frame 7 and is rotatably connected to the placement frame 7 and slidably connected to the main body 1.

[0028] In this embodiment, the clamping mechanism includes a first motor 2, a rotating rod 3, a lifting plate 4, a connecting rod 5, and a locking block 6. In use, the first motor 2, which is fixedly installed at the bottom of the placement frame 7 by the mounting bracket 24, drives the rotating rod 3 to rotate in the roller bearing 23 installed in the placement frame 7. This causes the limiting lifting plate 4 to engage with the rotating rod 3 threadedly, thereby allowing it to slide up and down in the placement frame 7. The connecting rod 5, which is rotatably connected to the lifting plate 4, begins to move under the action of the lifting plate 4, thereby pushing the locking block 6 to slide in the limiting groove 19. At this time, the rubber-coated wheel can be placed on the placement frame 7. Then, under the movement of the locking block 6, the rubber block 22 contacts the inside of the rubber-coated wheel, and the support plate 21 is also inserted into the bottom of the rubber-coated wheel, thereby fixing the rubber-coated wheel on the placement frame 7.

[0029] In this embodiment, the rotating assembly includes a placement frame 7, a second motor 8, a drive gear 9, and a first roller 10. In use, after the rubber-coated wheel is clamped and fixed, the second motor 8 is driven to directly drive the drive gear 9 to rotate, so that the drive gear 9 meshes with the driven gear 20 at the bottom of the placement frame 7, thereby allowing the placement frame 7 to rotate inside the main body 1. When the placement frame 7 rotates, the first roller on the placement frame 7 slides in the first sliding groove 18, while the placement frame 7 slides in the rotation groove 17, thereby completing the directional rotation of the rubber-coated wheel.

[0030] In this embodiment, the sliding mechanism includes a third motor 11, a lead screw 12, a sliding frame 13, and a second roller 14. In use, when the rubber-coated wheel on the placement frame 7 rotates a certain angle, the thickness of the rubber-coated wheel is measured again. Before this, in order to prevent the rubber-coated wheel from touching the measuring instrument 15 due to uneven wall thickness, the measuring instrument 15 slides back on the main body 1 to avoid the rubber-coated wheel. When measurement is required, the third motor 11 installed on the main body 1 is driven to allow the sliding frame 13, which is threaded with the lead screw 12, to slide inside the main body 1. The second roller 14 on the sliding frame 13 also slides in the second sliding groove 25 of the main body 1. When the position is appropriate, the probe 16 on the measuring instrument 15 is used to start measuring the thickness of the rubber-coated wheel. Example

[0031] In summary, during use, the rubber-coated wheel first needs to be installed on the placement frame 7. Driven by the first motor 2, which is fixedly mounted on the bottom of the placement frame 7 using the mounting bracket 24, the rotating rod 3 rotates within the roller bearing 23 installed in the placement frame 7. This causes the limiting lifting plate 4 to engage with the rotating rod 3 via threads, allowing it to slide up and down within the placement frame 7. The connecting rod 5, which is rotatably connected to the lifting plate 4, moves under the action of the lifting plate 4, pushing the locking block 6 to slide in the limiting groove 19. At this point, the rubber-coated wheel can be placed on the placement frame 7. Subsequently, with the movement of the locking block 6, the rubber block 22 contacts the inside of the rubber-coated wheel, and the support plate 21 is inserted into the bottom of the rubber-coated wheel, thus fixing the rubber-coated wheel on the placement frame 7. To prevent inaccurate measurement of rubber-coated wheels with uneven thickness, the rubber-coated wheel needs to be rotated. At this time, the second motor 8 drives the drive gear 9 directly, causing the drive gear 9 to engage with the driven gear at the bottom of the placement frame 7. The teeth 20 mesh, allowing the placement frame 7 to rotate inside the main body 1. When the placement frame 7 rotates, the first roller on the placement frame 7 slides in the first sliding groove 18, while the placement frame 7 slides in the rotation groove 17, thus completing the directional rotation of the rubber-coated wheel. When measuring the thickness of the rubber-coated wheel, after the rubber-coated wheel on the placement frame 7 rotates to a certain angle, the thickness of the rubber-coated wheel is measured again. Before this, in order to prevent the rubber-coated wheel from touching the measuring instrument 15 due to uneven wall thickness, the measuring instrument 15 slides back on the main body 1 to avoid the rubber-coated wheel. When measurement is required, the third motor 11 installed on the main body 1 drives the sliding frame 13, which is threaded with the lead screw 12, to slide inside the main body 1. The second roller 14 on the sliding frame 13 also slides in the second sliding groove 25 of the main body 1. When the position is appropriate, the probe 16 on the measuring instrument 15 is used to start measuring the thickness of the rubber-coated wheel.

[0032] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
