The other end of the spring is connected to a movable plate. The size of the movable plate is the same as that of the first slot. A dial rod is installed at the bottom end of the inner wall of the first slot. A contact switch is placed in the same horizontal height direction as the dial rod. The contact switch is connected to the movable plate. A roller is rotatably installed at the bottom end of the first fixing block. A warning light is installed on the fixing plate.

[0010] Preferably, a second rotating motor is installed at the center position of the top end inner wall of the positioning box.

[0015] Preferably, a plurality of air holes are evenly formed at the bottom end of the first fixing block. An air flow sensor is installed at one end of the positioning rod away from the rotating disk.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In the present invention, by providing a rotating disk, a fixed ring and a first camera, the hub to be detected is fixed on the rotating disk through a positioning rod. The rotating disk drives the hub to rotate. During the rotation of the hub, the appearance of the hub is photographed by the first camera, the second camera and the third camera. Then, the appearance of the hub can be detected to prevent obvious problems such as cracks on the outer side of the hub. During the rotation of the hub, the rollers can make the hub rotate more stably and not shake easily, making the photographed image more stable and clear. At the same time, if the hub is deformed or there is a protrusion at a certain part of the rim, during the rotation of the hub, the protruding part will directly squeeze the rollers. At this time, the whole first fixing block moves upward. When the dial rod contacts the contact switch, the warning light lights up. At this time, it proves that the surface of the rim of the hub is deformed or there is a protrusion, and the true roundness detection of the hub is completed.

[0018] In the present invention, by providing a second electric telescopic rod and a second rotating motor, after the second rotating motor drives the first fixing block to rotate 90 degrees, the hub stops rotating. At this time, the second electric telescopic rod starts to extend, so that a plurality of rollers squeeze the hub, and the compressive test of the hub can be carried out. The final result is analyzed through a computer screen. During normal use, the second electric telescopic rod can make the device adapt to hubs of different sizes.

[0019] In the present invention, by providing a grinding plate, when the compressive test of the hub is carried out, the grinding plate moves downward at this time, and then abuts against the rim surface together with the rollers. When squeezing the hub, it shares part of the pressure for the rollers and improves the service life of the rollers. If burrs are found on the rim surface, the grinding plate moves downward until the bottom end of the grinding plate contacts the rim surface. As the hub rotates, the burrs on the rim can be ground, and the grinding of the burrs on the rim surface is completed, making the subsequent processing of the hub more convenient. During the process of jetting air from the air holes to the rim surface, the two grinding plates can also play a role in gathering wind, making the wind force more concentrated.

[0020] In the present invention, by providing air holes and an air flow sensor, during the process of the grinding plate grinding the burrs, the air holes jet air outwards, which can complete the self-cleaning of the wheel hub. When detecting a tubeless wheel hub, during the rotation of the wheel hub, the air holes jet air outwards, and the air flow directly sprays onto the rim surface. At this time, the air holes continuously jet air towards the rim surface. If the air tightness of the wheel hub is not good, then gas will be sprayed to the air flow sensor, and the staff can judge the air tightness of the wheel hub based on the data transmitted by the air flow sensor.

Specific implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Referring to Figure 1-10 , an automatic detection device includes a fixed base 1. A fixed ring 3 is fixedly installed at the top of the fixed base 1. A rotating disk 4 is movably arranged on one side of the fixed ring 3. A fixing mechanism is arranged on the side of the rotating disk 4 close to the fixed ring 3. A first camera 8 is installed on the inner wall of the fixed ring 3. A first electric telescopic rod 9 is connected to the side wall of the fixed ring 3 far from the rotating disk 4. The telescopic end of the first electric telescopic rod 9 faces the center position of the fixed ring 3, and the telescopic end of the first electric telescopic rod 9 is connected to a second camera 10. A connecting plate 11 is connected to the inner wall of the fixed ring 3 close to the rotating disk 4. A second chute 12 is horizontally opened along the length direction of the connecting plate 11 on the side of the connecting plate 11 far from the rotating disk 4. A first electric slider 13 is slidably installed inside the second chute 12. A third camera 14 is connected to the side of the first electric slider 13 far from the second chute 12. A plurality of detection devices are installed on the inner wall of the fixed ring 3 along the circumferential direction. The hub to be detected is fixed on the rotating disk 4 through the fixing mechanism on the rotating disk 4. Subsequently, the rotating disk 4 drives the hub to rotate. During the rotation of the hub, the appearance of the hub is photographed by the first camera 8, the second camera 10 and the third camera 14. Subsequently, the appearance of the hub can be detected to prevent obvious problems such as cracks on the outer side of the hub. Through the detection device on the fixed ring 3, the true roundness of the hub can be detected.

[0034] As a technical optimization solution of the present invention, a fixing plate 2 is installed on one side of the top of the fixed base 1 away from the first electric telescopic rod 9. A first rotating motor 5 is installed on one side of the fixing plate 2 close to the rotating disk 4. The output end of the first rotating motor 5 is away from the fixing plate 2, and the output end of the first rotating motor 5 is connected to the rotating disk 4. A first sliding groove 6 is formed in the outer wall of the rotating disk 4 along the circumferential direction. A first sliding block 7 is slidably installed in the first sliding groove 6. One end of the first sliding block 7 away from the first sliding groove 6 is connected to the fixing plate 2. The first rotating motor 5 can drive the rotating disk 4 to rotate. The connection between the first sliding block 7 and the fixing plate 2 plays a supporting role for the rotating disk 4, preventing the first rotating motor 5 from being directly stressed and extending the service life of the first rotating motor 5.

[0035] As a technical optimization solution of the present invention, the fixing mechanism includes a fourth sliding groove 20, a third electric slider 21 and a positioning rod 22. A plurality of fourth sliding grooves 20 are formed at the center of the side of the rotating disk 4 close to the fixing ring 3. A third electric slider 21 is slidably installed in the fourth sliding groove 20. A positioning rod 22 is installed on the side of the third electric slider 21 away from the fourth sliding groove 20. Rubber is provided on the outer side of the positioning rod 22. The positioning rod 22 passes through the screw hole at the spoke of the automobile wheel hub. Then, the third electric slider 21 slides in the fourth sliding groove 20, driving the positioning rod 22 to move, and fixing the wheel hub on the rotating disk 4 through the positioning rod 22. The rubber on the positioning rod 22 can prevent the positioning rod 22 from damaging the screw hole on the wheel hub when fixing the wheel hub.

[0036] As a technical optimization solution of the present invention, the detection device includes a second electric telescopic rod 18, a positioning box 19 and a No. 1 fixed block 23. A plurality of second electric telescopic rods 18 are evenly placed on the inner wall of the fixed ring 3 along the circumferential direction. The telescopic end of the second electric telescopic rod 18 is toward the center position of the fixed ring 3. The telescopic end of the second electric telescopic rod 18 is connected to the positioning box 19. The No. 1 fixed block 23 is movably placed at the opening of the positioning box 19. The top of the No. 1 fixed block 23 is close to the end of the positioning box 19. The top of the first fixing block 23 is defined by a first slot 27. A spring 29 is mounted at the bottom of the inner wall of the first slot 27. The other end of the spring 29 is connected to a movable plate 28, which has the same dimensions as the first slot 27. A lever 30 is mounted at the bottom of the inner wall of the first slot 27. A contact switch 31 is positioned at the same level as the lever 30 and connected to the movable plate 28. A roller 35 is rotatably mounted at the bottom of the first fixing block 23, and a warning light 32 is mounted on the fixing plate 2. If the wheel hub deforms or a protrusion is present on the rim, the protrusion will directly press against the roller 35 during rotation. This will cause the first fixing block 23 to move upward as a whole, and the movable plate 28 to move downward relative to the inside of the first slot 27, compressing the spring 29. When the lever 30 contacts the contact switch 31, the warning light 32 illuminates, indicating that the wheel hub has failed the test, thus completing the roundness test.

[0037] As a technical optimization solution of the present invention, a second rotary motor 24 is installed at the center of the top of the inner wall of the positioning box 19. The output end of the second rotary motor 24 faces the first fixed block 23, and the output end of the second rotary motor 24 is movably connected to the movable plate 28. Sixth slide grooves 33 are provided on both side walls of the first slot 27 along the height direction of the first slot 27. A stabilizing slider 34 is slidably installed inside the sixth slide groove 33. The side of the stabilizing slider 34 close to the movable plate 28 is connected to the movable plate 28. The second rotary motor 24 can rotate the first fixed block 23 to facilitate subsequent operation steps. The movable plate 28 makes a relatively downward movement inside the first slot 27. At this time, the stabilizing slider 34 slides in the sixth slide groove 33, allowing the movable plate 28 to move smoothly, ensuring the smooth operation of the device.

[0038] As a technical optimization solution of the present invention, a third chute 15 is horizontally defined on the inner wall of the fixing ring 3 along the end wall. The third chute 15 is evenly distributed along the circumference of the inner wall of the fixing ring 3. The position and number of the third chute 15 correspond to the second electric telescopic rod 18. A second electric slider 16 is slidably mounted within the third chute 15. The side of the second electric slider 16 facing away from the third chute 15 is connected to the second electric telescopic rod 18. The second electric slider 16 slides within the third chute 15 to change the position of the first fixing block 23 on the wheel rim, facilitating the device's detection of the wheel rim.

[0039] As a technical optimization solution of the present invention, fifth sliding grooves 25 are respectively formed in the inner walls at both ends of the positioning box 19 along the height direction of the positioning box 19. Stable sliding blocks 26 are respectively installed on the end walls at both ends of the first fixing block 23 along the height direction of the first fixing block 23, and the stable sliding blocks 26 can slide inside the fifth sliding grooves 25. During the upward movement of the first fixing block 23, the stable sliding blocks 26 will slide in the fifth sliding grooves 25, making the movement of the first fixing block 23 more stable.

[0040] As a technical optimization solution of the present invention, two seventh sliding grooves 36 are respectively formed in the side walls at both sides of the first fixing block 23 along the height direction of the first fixing block 23. The two seventh sliding grooves 36 on each side of the first fixing block 23 are symmetric along the central height direction of the first fixing block 23. Fourth electric sliders 37 are slidably installed inside the seventh sliding grooves 36. Grinding plates 38 are respectively placed movably on both sides of the first fixing block 23. One side of the grinding plate 38 close to the fourth electric slider 37 is connected to the fourth electric slider 37. If burrs are found on the rim surface, the fourth electric slider 37 slides downward in the seventh sliding groove 36, making the bottom end of the grinding plate 38 contact the rim surface. As the hub rotates, the burrs on the rim can be ground. During the process of the air holes 39 jetting air towards the rim surface, the two grinding plates 38 can also play a role in wind gathering, making the wind more concentrated. The grinding plates 38 move downward and then contact the rim surface together with the rollers 35. At this time, the second electric telescopic rod 18 starts to extend, so that the multiple rollers 35 and the grinding plates 38 press the hub, and the compressive test of the hub can be carried out. The final result is analyzed through the computer graphics.

[0041] As a technical optimization solution of the present invention, a trapezoidal groove 41 is formed in the top of the movable plate 28 along the end wall direction of the first fixing block 23. The trapezoidal groove 41 also penetrates through one side wall of the first fixing block 23. A trapezoidal sliding block 42 is slidably installed inside the trapezoidal groove 41. One end of the trapezoidal sliding block 42 far away from the trapezoidal groove 41 is connected to the output end of the second rotating motor 24. If the rim is inclined, the staff can pull out the first fixing block 23 outward. When the trapezoidal sliding block 42 disengages from the trapezoidal groove 41, the first fixing block 23 is successfully removed. At this time, the staff installs the second fixing block 43 at the trapezoidal sliding block 42, and then repeats the above steps to detect the hub, enabling the device to detect a variety of hubs and improving the use convenience of the device at the same time.

[0042] As a technical optimization solution of the present invention, a plurality of air holes 39 are evenly opened at the bottom end of the first fixing block 23, and an air flow sensor 40 is installed at one end of the positioning rod 22 away from the rotating disk 4. During the process of the grinding plate 38 grinding burrs, the air holes 39 eject air outward, which can complete the self-cleaning of the wheel hub. When detecting a tubeless wheel hub, during the rotation of the wheel hub, the air holes 39 eject air outward, and the air flow directly sprays onto the rim surface. At this time, the air holes 39 continuously spray air onto the rim surface. If the airtightness of the wheel hub is not good, gas will be sprayed to the air flow sensor 40, and the staff can judge the airtightness of the wheel hub based on the data transmitted by the air flow sensor 40.

[0043] When the present invention is in use, the staff picks up the automobile wheel hub to be detected through the automobile wheel hub clamping tool, then turns one side of the wheel spoke towards the fixing ring 3, and then pushes the automobile wheel hub into the inside of the fixing ring 3. The positioning rod 22 passes through the screw hole at the wheel spoke of the automobile wheel hub. Then, the third electric slider 21 slides in the fourth chute 20, driving the positioning rod 22 to move, and fixing the wheel hub on the rotating disk 4 through the positioning rod 22. The rubber on the positioning rod 22 can prevent the positioning rod 22 from damaging the screw hole on the wheel hub when fixing the wheel hub. Then, the second electric telescopic rod 18 is started to push the positioning box 19, so that the rollers 35 on the first fixing block 23 are in contact with the rim. The first rotating motor 5 is started to drive the rotating disk 4 to rotate. Since the wheel hub is fixed on the rotating disk 4, the wheel hub rotates together with the rotating disk 4. During the rotation of the wheel hub, the first camera 8, the second camera 10 and the third camera 14 take pictures of the basic situation on the outer side of the wheel hub and transmit them to the computer in the background in real time. The staff can judge the appearance of the wheel hub through the computer screen, and the picture can be saved. When problems occur in the wheel hub later, the corresponding video can be directly retrieved for recheck. During the installation of the wheel hub, the first electric telescopic rod 9 drives the second camera 10 to move up and down. The second camera 10 will not interfere with the installation of the wheel hub, and the shooting angle can be adjusted according to the size of the wheel hub later. Similarly, when the third camera 14 shoots wheel hubs of different sizes, the shooting angle is adjusted by the first electric slider 13 moving up and down at the connecting plate 11, making the process of appearance detection smoother.

[0044] During the rotation of the wheel hub, the roller 35 abuts against the rim, which can make the wheel hub more stable during rotation and not easily shake, making the captured picture more stable and clear. At the same time, if the wheel hub is deformed or there is a protrusion somewhere on the rim, during the rotation of the wheel hub, the protruding part will directly press the roller 35. At this time, the whole first fixing block 23 moves upward. During the upward movement of the first fixing block 23, the stable slider 26 will slide in the fifth chute 25, making the movement of the first fixing block 23 more stable. The movable plate 28 is connected to the second rotating motor 24, so the movable plate 28 moves relatively downward inside the first slot 27. At this time, the stable slider 34 slides in the sixth chute 33, enabling the movable plate 28 to move smoothly and ensuring the smooth operation of the device. The movable plate 28 presses the spring 29. When the lever 30 contacts the contact switch 31, the warning light 32 lights up, indicating that the wheel hub is unqualified. The second electric slider 16 slides in the third chute 15, which can make the roller 35 detect the entire surface of the rim, making the detection result more accurate. The second fixing block 43 is a substitute for the first fixing block 23, and the second fixing block 43 has the same structure as the first fixing block 23. The only difference is that a bevel wheel 44 is rotatably installed at the bottom of the second fixing block 43, and the inclination of the bevel wheel 44 is the same as that of the rim. If the rim is inclined, the staff can pull out the first fixing block 23 outward. When the trapezoidal slider 42 disengages from the trapezoidal groove 41, the first fixing block 23 is successfully removed. At this time, the staff installs the second fixing block 43 at the trapezoidal slider 42, and then repeats the above steps to detect the wheel hub.

[0045] During the detection of the wheel hub, if burrs are found on the rim surface, the second electric telescopic rod 18 retracts, so that the roller 35 no longer contacts the rim surface. Then, the second rotating motor 24 drives the first fixing block 23 to rotate 90 degrees. Then, the fourth electric slider 37 slides downward in the seventh chute 36, making the bottom end of the grinding plate 38 contact the rim surface. As the wheel hub rotates, the burrs on the rim can be ground. By sliding the second electric slider 16, the position of the grinding plate 38 can be adjusted, enabling the grinding plate 38 to grind the burrs at different positions on the rim surface. The air holes 39 are connected to the air pipe, and during grinding, the air holes 39 jet air outward, which can complete the self-cleaning of the wheel hub. If there are no burrs on the wheel hub, the grinding plate 38 does not need to abut against the rim.

[0046] After the second rotating motor 24 drives the first fixing block 23 to rotate 90 degrees, the wheel hub stops rotating. At this time, the grinding plate 38 moves downward, and then abuts against the rim surface together with the roller 35. At this time, the second electric telescopic rod 18 starts to extend, so that multiple rollers 35 and the grinding plate 38 press the wheel hub, and the compressive strength test of the wheel hub can be carried out, and the final result is analyzed through the computer graphics.

[0047] When detecting a tubeless wheel hub, during the rotation of the wheel hub, the air hole 39 jets out air, and the air flow directly sprays onto the rim surface. At this time, the two grinding plates 38 can also play a role in gathering the wind, making the wind force more concentrated. The air hole 39 continuously jets air towards the rim surface. If the airtightness of the wheel hub is not good, then gas will be sprayed to the air flow sensor 40, and the staff can judge the airtightness of the wheel hub based on the data transmitted by the air flow sensor 40.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered within the protection scope of the present invention.
