[0032] Specifically, the shooting and detection methods of the first detection camera 3 and the second detection camera 301 are relatively common technical means in the existing technical applications, and will not be elaborated here.

[0033] like Figure 1-Figure 7 As shown, the flip assembly includes a fixed block 419 arranged on the top of the mounting seat 405, the top of the mounting seat 405 is fixedly connected with a slide rod 406, the upper end of the slide rod 406 passes through the fixed block 419, a second hydraulic push rod 407 is arranged on the top of the mounting seat 405, the output shaft of the second hydraulic push rod 407 is fixedly connected to the bottom of the fixed block 419, a third motor 420 is arranged on one side of the fixed block 419, the output shaft of the third motor 420 passes through the fixed block 419 and is fixedly connected to the connecting plate 418.

[0034] The surface of the connecting plate 418 is slidably connected to two symmetrically distributed mounting plates 415, and mounting blocks 416 are fixedly connected to opposite sides of the two mounting plates 415.

[0037] After the inspection of the outer side of the wheel hub is completed at the first inspection camera 3 by driving the motor 101, the rotating rod 102 and the turntable 1, the wheel hub is moved to the front of the flip assembly. At this time, the second motor 403 can be started to drive the screw rod 404 to rotate so that the flip assembly is close to the wheel hub, and the third hydraulic push rod 409 can be started to drive the two mounting plates 415 to approach each other to clamp the wheel hub, and the electromagnet 417 is energized to strengthen the clamping effect of the wheel hub, wherein the mounting plate 415 is a rubber material component. After the clamping is completed, the second hydraulic push rod 407 is started to drive the fixed block 419 to move upward, so that the wheel hub is separated from the flip assembly, and the wheel hub is misaligned with the placement mechanism 2 under the reverse rotation of the second motor 403. After starting the third motor 420, the connecting plate 418 can be rotated 180 degrees to achieve the effect of flipping the wheel hub, and then the above steps are repeated to install the wheel hub on the placement mechanism 2 and cooperate with the second inspection camera 301 to inspect its inner side;

[0038] In order to avoid collision with the second detection camera 301 during flipping and moving of the wheel hub, the sleeve 402, the mounting column 414, the mounting shell 411 and the sliding rod 410 work together to achieve the effect of self-adjusting the height of the second detection camera 301 according to the position of the fixed block 419, thereby preventing the second detection camera 301 from colliding during moving or flipping the wheel hub.

[0039] like Figure 1-Figure 7 As shown, the placement mechanism 2 includes a placement plate 201 fixedly connected to the surface of the turntable 1, a first motor 204 is arranged at the bottom of the placement plate 201, a rotating plate 202 is rotatably connected to the top of the placement plate 201, an integrally formed driving rod is fixedly connected to the bottom of the rotating plate 202, and the lower end of the driving rod passes through the rotating plate 202 and is fixedly connected to the output shaft of the first motor 204, and an integrally formed support column 203 is fixedly connected to the top of the rotating plate 202.

[0040] A first hydraulic push rod 205 is provided on the inner wall of the driving rod, and a storage cavity located above the first hydraulic push rod 205 is opened inside the driving rod. The output shaft of the first hydraulic push rod 205 passes through the interior of the storage cavity and is fixedly connected to a push block 206. Hydraulic oil is filled between the top of the push block 206 and the storage cavity.

[0041] The surface of the support column 203 is provided with two groups of top blocks 209, and the number of each group of top blocks 209 is two. The interior of the support column 203 is provided with a through groove 207 connected to the storage cavity. The interior of the support column 203 is provided with an installation cavity corresponding to the top block 209, and the inner wall of the through groove 207 is provided with a through hole connected to the installation cavity.

[0042] An adjusting block 210 is slidably connected to the inner wall of the installation cavity, a connecting rod 208 is fixedly connected to one side of the adjusting block 210, the other end of the connecting rod 208 passes through the support column 203 and is fixedly connected to the surface of the adjacent top block 209, and a spring 211 is fixedly connected between the surface of the adjusting block 210 and the inner wall of the installation cavity.

[0043] By installing the center hole on the wheel hub on the support column 203, the surface of the wheel hub is in contact with the rotating disk 202, and starting the first hydraulic push rod 205 can drive the push block 206 to slide along the inner wall of the storage cavity. In this process, the hydraulic oil is injected into the inner wall of the installation cavity through the through groove 207 and the through hole, and the adjustment block 210 is pushed by the hydraulic oil to make the connecting rod 208 drive the top block 209 away from the support column 203, so that the top block 209 can be used to limit the wheel hub from the inner wall of the center hole on the wheel hub. Then, by starting the first motor 204, the wheel hub can be driven to rotate synchronously during the process of rotating the rotating disk 202 driven by the driving rod, so that the first detection camera 3 and the second detection camera 301 can detect different positions of the wheel hub, wherein the setting of the two groups of top blocks 209 can match the position of the center hole before and after the wheel hub is flipped, so as to achieve a good clamping effect;

[0044] When the wheel hub needs to be removed, the first hydraulic push rod 205 drives the push block 206 to reset, and the top block 209 is driven to reset under the action of the spring 211. At the same time, the hydraulic oil inside the installation cavity is squeezed by the adjustment block 210 and guided back to the storage cavity through the through groove 207 for storage in the storage cavity for reuse.

[0045] Working principle: by installing the center hole on the wheel hub on the support column 203, the surface of the wheel hub is in contact with the rotating disk 202, and starting the first hydraulic push rod 205 can drive the push block 206 to slide along the inner wall of the storage cavity. In this process, the hydraulic oil is injected into the inner wall of the installation cavity through the through groove 207 and the through hole, and the adjustment block 210 is pushed by the hydraulic oil to make the connecting rod 208 drive the top block 209 away from the support column 203, so that the top block 209 can be used to limit the wheel hub from the inner wall of the center hole on the wheel hub. Then, by starting the first motor 204, the wheel hub can be driven to rotate synchronously during the process of rotating the rotating disk 202 driven by the driving rod, so that the first detection camera 3 and the second detection camera 301 can detect different positions of the wheel hub, wherein the setting of the two sets of top blocks 209 can match the position of the center hole before and after the wheel hub is flipped, so as to achieve a good clamping effect, and the driving motor 1 01. After the rotating rod 102 and the turntable 1 complete the inspection of the outer side of the wheel hub at the first inspection camera 3, the wheel hub is moved to the front of the flipping assembly. At this time, the second motor 403 can be started to drive the screw rod 404 to rotate the flipping assembly close to the wheel hub, and the third hydraulic push rod 409 can be started to drive the two mounting plates 415 to approach each other to clamp the wheel hub. At the same time, the electromagnet 417 is energized to enhance the clamping effect of the wheel hub, wherein the mounting plate 415 is a rubber material component. After the clamping is completed, the second hydraulic push rod 407 is started to drive the fixed block 419 to move upward, so that the wheel hub is separated from the flipping assembly, and under the reverse rotation of the second motor 403, the wheel hub is misaligned with the placement mechanism 2, and then the third motor 420 is started to drive the connecting plate 418 to rotate one hundred and eighty degrees to achieve the effect of flipping the wheel hub, and then the above steps are repeated to install the wheel hub on the placement mechanism 2 and cooperate with the second inspection camera 301 to inspect its inner side.
