Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] See Figures 1 to 5 This embodiment discloses a wheel rim flatness testing device, including a support platform 100. A rotatable testing ring 200 is mounted on the support platform 100. The testing ring 200 has multiple equidistantly arranged annular telescopic grooves 210. Telescopic members 300, capable of moving circumferentially along the telescopic grooves 210, are disposed within each telescopic groove 210. A contact wheel 301 is mounted on one end of the telescopic member 300 facing the inner side of the testing ring 200. A support plate 400 is provided on the outer wall of the testing ring 200. The other end of the telescopic member 300 extends to the support plate 400. A rotatable rotating rod 410 is mounted on the support plate 400. A testing rod 411 is connected to the top of the rotating rod 410. An indicator rod 420 extending vertically is connected to the support plate 400. The end of the telescopic member 300 extending to the support plate 400 abuts against the rotating rod 410, and the movement of the telescopic member 300 drives the rotating rod 410 to rotate. The wheel hub is placed in the detection ring 200, so that the contact wheel 301 can contact the wheel rim. When the flatness of the wheel rim is uneven, each telescopic component 300 will move to different degrees, so that each rotating rod 410 and detection rod 411 rotate at different angles. The flatness of the wheel rim can be directly determined by comparing the indicator rod 420 with the detection rod 411.

[0026] The telescopic member 300 includes a support portion 310, a connecting portion 320, and an abutting portion 330. The support portion 310 is placed in the telescopic groove 210. The connecting portion 320 connects to the end of the telescopic member 300 facing the inner side of the detection ring 200. The contact wheel 301 is installed at the end of the connecting portion 320. The abutting portion 330 connects to the end of the telescopic member 300 facing the outer side of the detection ring 200 and abuts against the rotating rod 410. The opening of the telescopic groove 210 facing the inner side of the detection ring 200 is provided with a first guide surface 211 inclined towards the center of the telescopic groove 210. The telescopic member 300 is provided with a second guide surface 311 that cooperates with the first guide surface 211. By cooperating with the first guide surface 211 and the second guide surface 311, it can be ensured that the telescopic member 300 is always in the center of the telescopic groove 210 when the contact wheel 301 contacts the rim, thereby ensuring that the height of each contact wheel 301 is consistent and preventing detection errors caused by inconsistent contact points between the curved rim and the contact wheel 301.

[0027] The sidewall of the telescopic groove 210 is provided with a first guide groove 220 extending toward the center of the telescopic groove 210. A first moving block 221 is provided in the first guide groove 220. A first roller 223 is provided at one end of the first moving block 221 extending out of the first guide groove 220. A first spring 222 is provided in the first guide groove 220. The first spring 222 pushes the first moving block 221 toward the support part 310 so that the first roller 223 abuts against the support part 310. At the same time, the sidewall of the telescopic groove 210 is provided with a second guide groove 230 extending toward the center of the telescopic groove 210. A second moving block 231 is provided in the second guide groove 230. A second roller 233 is provided at one end of the second moving block 231. A second spring 232 is provided in the second guide groove 230. The second spring 232 pushes the second moving block 231 toward the support part 310 so that the second roller 233 abuts against the support part 310. The support portion 310 has a third guide surface 312 on its side wall. The third guide surface 312 extends from the outside of the detection ring 200 to the inside of the detection ring 200 and is inclined toward the center of the telescopic groove 210. The first roller 223 and the second roller 233 abut against the third guide surface 312. The third guide surface 312 causes the support portion 310 to gradually increase in size from the outside of the detection ring 200 to the inside of the detection ring 200, thereby allowing the first roller 223 and the second roller 233 to restrict the telescopic member 300 from moving toward the outside of the detection ring 200, thus ensuring that the contact wheel 301 can stably abut against the rim, thereby ensuring the accuracy of the detection.

[0028] A support platform 100 is connected to an upwardly extending support rod 110. A second support ring 600 is connected to the top of the support rod 110. A first support ring 500 is located at the bottom of the detection ring 200. The first support ring 500 includes a downwardly extending first connecting ring 510. The second support ring 600 has a second connecting groove 620 corresponding to the position of the first connecting ring 510. A first ball bearing 530 is disposed within the second connecting groove 620. The first connecting ring 510 is embedded in the second connecting groove 620 and contacts the first ball bearing 530. The second support ring 600 also includes an upwardly extending second connecting ring 610. The first support ring 500 has a first connecting groove 520 corresponding to the position of the second connecting ring 610. A second ball bearing 630 is disposed within the first connecting groove 520. The second connecting ring 610 is embedded in the first connecting groove 520 and contacts the second ball bearing 630. This allows the detection ring 200 to rotate, facilitating the inspection of areas where the difference between the detection rod 411 and the indicator rod 420 is too large.
