Description

Technical Field

[0001] This utility model relates to the field of tire testing technology, and in particular to a three-dimensional scanning test bench for pneumatic tires or rims. Background Technology

[0002] In recent years, with the widespread use of highways and the development of the automotive industry, vehicle speeds have increased significantly. Correspondingly, the demands on the quality and performance of tires, a major component of automobiles, have become increasingly stringent. When a car travels at high speeds, it experiences various deformations, loads, forces, and extreme temperatures, causing tire or rim deformation. Irregularities in the tire's shape and profile can significantly impact driving safety. Therefore, the inspection of automotive tires and rims is particularly important. However, contact testing of tire or rim surfaces suffers from low automation, low measurement accuracy, and the potential for damage to the tire itself. Therefore, non-contact testing is of paramount importance.

[0003] 3D scanning of pneumatic tires or rims captures coordinate information from the tire or rim surface using marker points. Therefore, before scanning, marker points need to be attached to the tire or rim surface. Due to limitations in equipment size and laser irradiation distance, smaller tires are scanned on a test bench, while larger tires or individual rims are scanned directly on the ground. Regardless of placement, the bottom of the tire always contacts a flat surface. Furthermore, pneumatic tires using commercial rims cannot stand independently; without proper support, they are prone to tilting or falling over, affecting scan quality or preventing scanning altogether.

[0004] Existing technology involves scanning the tires, which is inconvenient for locating tires of different sizes and requires additional lifting structures for installation, resulting in poor operational efficiency.

[0005] Based on this, a three-dimensional scanning test bench for pneumatic tires or rims is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

A tire positioning component for fixing the tire is located between the two lifting slides. A driving component for rotating the tire positioning component is mounted on the lifting slide. A displacement component for displacement is located at the lower end of the vertical guide rods. The lifting slide is connected to a lifting component for moving it up and down. The height of the tire positioning component is adjusted by the lifting component to load and unload the tire. The tire positioning component includes a fixed plate. A positioning outer frame is coaxially mounted on the outside of the fixed plate. The positioning outer frame is connected to the fixed plate by multiple crossbars.

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.

[0031] like Figures 1-7 As shown, this utility model embodiment provides a three-dimensional scanning test bench for pneumatic tires or rims, including a top plate 100. Two sets of vertical guide rods 105 are symmetrically arranged on both sides of the lower end of the top plate 100. A lifting slide 102 is slidably mounted on each set of vertical guide rods 105. A tire positioning component 200 for fixing the tire is provided between the two lifting slides 102. A driving component 300 for rotating the tire positioning component 200 is provided on the lifting slide 102. A displacement component for displacement is provided at the lower end of the vertical guide rods 105. The lifting slide 102 is connected to... The lifting component that drives the tire positioning component 200 to move up and down is used to adjust the height of the tire positioning component 200 so as to load and unload the tire. The tire positioning component 200 includes a fixed plate 201. A positioning outer frame 210 is coaxially provided on the outer side of the fixed plate 201. The positioning outer frame 210 is connected to the fixed plate 201 through multiple crossbars. Two lifting lugs 211 are symmetrically provided on the outer side of the positioning outer frame 210. Each lifting lug 211 is provided with a flipping shaft that matches the drive component 300. The fixed plate 201 is provided with a clamping mechanism for circumferential positioning of the tire.

[0032] The clamping mechanism includes synchronized slide grooves 208 arrayed on the upper end of the fixed disk 201. A synchronized slider 202 slides in each synchronized slide groove 208. The upper end of the synchronized slider 202 is provided with a set of limiting rollers that match the outer side of the tire. An adjusting screw 206 is rotatably provided in each synchronized slide groove 208. The adjusting screw 206 is threadedly connected to the synchronized slider 202. The outer side of the fixed disk 201 is provided with a synchronized drive component that drives multiple adjusting screws 206 to rotate synchronously. The synchronized drive component drives the adjusting screws 206 and the synchronized slider 202 to rotate relative to each other. Under the action of the thread, the synchronized slider 202 slides along the inner wall of the synchronized slide groove 208. The set of limiting rollers on the synchronized slider 202 moves towards the center of the fixed disk 201 at the same time to lock the tire position.

[0033] The synchronous drive component includes a synchronous gear 209 fixedly mounted on the outer end of the adjusting screw 206. The lower sides of multiple synchronous gears 209 mesh with a rotating gear frame 207. A positioning outer ring 216 is rotatably provided on the outer side of the rotating gear frame 207. The positioning outer ring 216 is connected and fixed to the positioning outer frame 210 through a hanger 215. A first gear 212 is coaxially mounted on the shaft end of one of the synchronous gears 209. The upper side of the first gear 212 meshes with a second gear 213. The second gear 213 is connected to a drive motor 214 for driving its rotation. The drive motor 214 is mounted on the upper end of the positioning outer frame 210. Under the drive of the drive motor 214, the second gear 213 matches the first gear 212 to drive one of the synchronous gears 209 to rotate. The synchronous gear 209 cooperates with the rotating gear frame 207 to make multiple adjusting screws 206 rotate synchronously, providing synchronous power for clamping.

[0034] The limiting roller assembly includes a central shaft 218 fixed to the upper end of the synchronous slider 202. A stator 217 is fixedly provided on the outer side of the central shaft 218. A limiting post 204 is rotatably provided on the outer side of the central shaft 218. A rotor matching the stator 217 is provided on the inner wall of the limiting post 204. A first limiting disk 203 is provided at the upper end of the limiting post 204. A second limiting disk 205 is fixed at the bottom of the limiting post 204. The distance between the first limiting disk 203 and the second limiting disk 205 is greater than the width of the tire. When the stator 217 is energized, the rotor inside the limiting post 204 will rotate, thereby driving the limiting post 204 to rotate. This allows the clamped tire to rotate for better scanning and detection.

[0035] The outer side of the limiting post 204 is provided with anti-slip pads, which can reduce damage to the wheel rim;

[0036] The lifting component includes lifting rods 101 symmetrically arranged on the upper end of the top plate 100. The output end of the lifting rods 101 passes through the top plate 100 and is connected and fixed to the lifting slide 102. The lifting rods 101 move up and down, thereby providing power for the lifting slide 102 to slide up and down. The lifting rods 101 are hydraulic push rods.

[0037] The displacement component includes a displacement seat 103 fixed to the lower end of the vertical guide rod 105. The displacement seat 103 is symmetrically provided with traveling wheels 104, which can adjust the detection position and improve the flexibility of detection.

[0038] To further improve the flexibility of displacement, the displacement seat 103 is equipped with a walking motor that drives the walking wheel 104 to rotate. The walking wheel 104 is a Mecanum wheel, which is used to enable the equipment to move in confined spaces.

[0039] The driving component 300 includes a worm gear 301 fixedly connected to the flipping shaft end of the tire positioning component 200. The lower side of the worm gear 301 meshes with a worm 304. One end of the worm 304 is fixedly connected to the output end of the flipping motor 302. The lower end of the lifting slide 102 is provided with a first fixing bracket 303 to facilitate the installation of the flipping motor 302. The lower end of the lifting slide 102 is also provided with a second fixing bracket 305 rotatably connected to the shaft end of the worm 304. Under the drive of the flipping motor 302, the worm 304 matches the worm gear 301, thereby driving the flipping shaft to rotate and adjusting the clamping direction of the tire positioning component 200, making subsequent loading and unloading more convenient.

[0040] Working principle: In actual use, the displacement component moves the device above the tire or rim to be inspected. Then, the lifting component lowers the tire positioning component 200, and the drive component 300 flips the tire positioning component 200 so that its clamping surface faces downward. At this time, power is input through the synchronous drive component, and multiple limit posts 204 on the clamping mechanism move towards the center simultaneously. It should be noted that the first limit plate 203 is flush with the ground. The multiple first limit plates 203 squeeze the outer side of the tire or rim, thereby detaching the tire or rim from the ground. Then, the movement continues, so that the multiple limit posts 204 clamp the outer side of the tire, completing the process. After initial locking, the drive component 300 drives the tire positioning component 200 to rotate, so that the tire lands on the upper end of the fixed plate 201. Then, the distance between the limiting posts 204 is slowly adjusted, so that the tire slowly falls until it is supported by the support surface constructed by the second limiting plate 205. During the scanning operation, the limiting roller group works and powers the stator 217, so that the rotor inside the limiting post 204 will rotate, thereby driving the limiting post 204 to rotate. This allows the clamped tire to rotate, so as to better scan and detect, without the problem of clamping dead angles affecting the scanning, ensuring the scanning quality, and facilitating unloading later.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
