Therefore, the safety of the wheel is very worthy of attention.

DETAILED DESCRIPTION

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] like Figure 1-Figure 7 A nondestructive flaw detection device for vehicle wheel components shown in the figure comprises a detection chassis 1 and a radiation detector 2. The radiation detector 2 is connected to a computer terminal, which is a mature technology in the prior art and will not be described in detail here.

[0030] The conveying mechanism includes a conveying motor 23, a pair of conveying motors 23 are provided, and both conveying motors 23 are fixedly connected to the far side of the conveying plate 4, and both ends of the close side of the conveying plate 4 are rotatably connected to conveying rollers 24, and a conveying belt 25 is transmission-connected between the conveying rollers 24, and the output end of the conveying motor 23 passes through the conveying plate 4 and is fixedly connected to the side wall of one of the conveying rollers 24;

[0031] When the wheel hub is inspected, the processed wheel hub is transported between the conveying plates 4 through the production conveyor line, and then the conveying motor 23 is controlled to start and drive the conveying roller 24 to rotate, and then the conveyor belt 25 is driven to transmit between the two conveying rollers 24, and then the wheel hub conveyor belt is inspected under the radiation detector 2 in the chassis 1, and the conveying motor 23 can be controlled to be closed, and then the radiation detector 2 can be controlled to start, and the detected data is transmitted to the terminal. At the same time, the detection motor 9 is controlled to start and drive the rotating plate 10 to rotate, and then the extrusion plate 14, the fixing seat 31 and the roller 32 are driven to rotate through the T-block 12. At this time, the roller 32 slides from the adjustment plate 16 to the ring 17, maintaining the extrusion effect on the T-block 12, and then the radiation detector 2 is driven by the U-shaped plate 7 to perform circumferential rotation detection above the wheel roller, and then the rotating plate 10 rotates one circle and returns to the initial position after the detection is completed, and the conveying motor 23 can be controlled to start and the inspected wheel hub is transported away, and the non-destructive flaw detection of the wheel hub is repeatedly realized in this way.

[0032] The linkage mechanism includes a U-shaped plate 7, a support frame 8 is fixedly connected to the top of the round frame 6, a detection motor 9 is fixedly connected to the top of the support frame 8, a rotating plate 10 is rotatably connected to the middle position of the bottom of the support frame 8, an inwardly sunken T-shaped slot 11 is provided at the bottom of the rotating plate 10, a T-shaped block 12 is slidably connected to the inside of the T-shaped slot 11, a spring 13 is fixedly connected between the side wall of the T-shaped block 12 and the inside of the T-shaped slot 11, and an extrusion plate 14 is fixedly connected to the bottom of the T-shaped block 12;

An adjusting plate 16 is slidably connected to the inner side of the notch 15. The bottom of the squeezing plate 14 is extended and arranged beside one of the circular rings 17.

[0034] The adjusting mechanism includes a bidirectional screw rod 19, which is rotatably connected to the inner side of the groove 3, and the side wall of the bidirectional screw rod 19 passes through the front side of the detection chassis 1 and is fixedly connected to a hand wheel 20. The hand wheel 20 facilitates the quick rotation of the bidirectional screw rod 19 to adjust the spacing between the conveying plates 4. The bottom of the conveying plate 4 is fixedly connected to a sliding block 21, and the bidirectional screw rod 19 is threadedly connected to the inner side wall of the sliding block 21. A pair of guide rods 22 are fixedly connected to the inner side of the groove 3 and are arranged through the inner side wall of the sliding block 21. Through the arrangement of the guide rods 22, it can be The bidirectional screw 19 plays a guiding role in the process of driving the sliding block 21 to move, so as to prevent the sliding block 21 from rotating with the bidirectional screw 19, thereby improving the stability of the device during operation. A scale value slot 38 is provided at the bottom end of the detection chassis 1. By setting the scale value slot 38, when adjusting the position of the conveying plate 4, the position of the conveying plate 4 on the scale value slot 38 can be observed, and the spacing between the conveying plates 4 can be accurately adjusted according to the size of the hub to ensure that the hub is located at the center. The radiation detector 2 can perform rotation detection on the hub more accurately.

[0035] When the detection device needs to be adjusted when detecting wheels of different sizes, the hand wheel 20 is first rotated to drive the bidirectional screw 19 to rotate, and then the two threaded sliding blocks 21 are driven to move closer or farther away from each other. At this time, the position of the conveying plate 4 on the scale value groove 38 can be observed to achieve accurate adjustment of the spacing between the conveying plates 4. During the movement of the conveying plate 4, the connecting tube 18 is driven by the connecting plate 28 to make the adjusting plate 16 slide at the notch 15, so that the roller 32, the fixing seat 31 and the extruding plate 14 make the T-block 12 Sliding in the T-slot 11, when the conveying plate 4 is accurately adjusted according to the hub size, the adjusting plate 16 will squeeze the roller 32 to the side of the corresponding ring 17, and at the same time drive the T-block 12 to slide and stretch the spring 13, so that the roller 32 is close to the side wall of the adjusting plate 16 under the tension of the spring 13, and then the radiation detector 2 will be driven to move through the U-shaped plate 7 to adjust the rotation radius of the radiation detector 2, thereby realizing the simultaneous adjustment of the positions of the conveying unit and the detection unit without adjusting them one by one, which greatly improves the detection efficiency of the device and increases the convenience of the device.

[0036] In order to be able to adjust the height of the detection unit according to the height of different wheel hubs, a pair of electric telescopic cylinders 26 are fixedly connected to the top of the detection chassis 1, and fixed ears 27 are fixedly connected to both sides of the top of the round frame 6. The output end of the electric telescopic cylinder 26 passes through the top of the detection chassis 1 and is fixedly connected to the top of the fixed ear 27. A connecting plate 28 is fixedly connected to the top of one of the conveying plates 4, and the connecting plate 28 is slidably connected to the inner side of the connecting cylinder 18;

[0037] When detecting wheels of different widths, it is necessary to adjust the height of the radiation detector 2 to ensure a more accurate detection effect. The electric telescopic cylinder 26 can be controlled to start pulling the fixed ear 27 to drive the round frame 6 to move up or down, and then the radiation detector 2 can be driven up and down by the support frame 8, the rotating plate 10, and the U-shaped plate 7 to adjust the detection height. At the same time, in the process of the round frame 6 sliding up and down, the connecting tube 18 will be driven to slide on the connecting plate 28 to ensure the connection between the conveying plate 4 and the adjusting plate 16, and will not hinder the up and down sliding of the round frame 6.

[0038] In order to prevent the adjustment plate 16 from falling, the adjustment plate 16 is set to an arc shape, so that the roller 32 can move from the adjustment plate 16 to the ring 17 more smoothly. Positioning grooves 29 are provided at both ends of the inner side of the notch 15, and positioning blocks 30 adapted to the positioning grooves 29 are fixedly connected on both sides of the adjustment plate 16;

[0039] The positioning groove 29 and the positioning block 30 can be used to position the adjustment plate 16, restrict the adjustment plate 16 from sliding in the notch 15, avoid falling directly with the connecting tube 18, and improve the stability of the device during operation.

[0040] In order to improve the smoothness of the linkage mechanism during detection, a fixing seat 31 is fixedly connected to the bottom of the extrusion plate 14, a roller 32 is rotatably connected to the inner side of the fixing seat 31, and the outer wall of the roller 32 is in contact with the side wall of the adjustment plate 16;

[0041] By setting the fixed seat 31 and the roller 32, the roller 32 can be squeezed by the ring 17 when the detection motor 9 drives the extrusion plate 14 to rotate, avoiding direct friction between the extrusion plate 14 and the ring 17 to affect the smoothness during the detection process and to improve the service life of the device.

[0042] In order to ensure that the extrusion plate 14 can accurately rotate to the notch 15 after one circle of detection, a travel switch 33 is fixedly connected to the side wall of the support frame 8 and located above the notch 15, and a touch rod 34 for touching the travel switch 33 is fixedly connected to the top of the rotating plate 10, and the travel switch 33 is electrically connected to the detection motor 9 through the controller;

[0043] When the detection motor 9 is controlled to start and drive the rotating plate 10 and the radiation detector 2 to rotate for detection, when the rotating plate 10 rotates one circle and moves above the notch 15, it will drive the touch rod 34 to touch the touch end of the travel switch 33, and then the travel switch 33 transmits a signal to the controller, and the controller controls the detection motor 9 to stop working, thereby ensuring that the rotating plate 10 accurately rotates to the notch 15, avoiding affecting the adjustment of the position of the radiation detector 2, and improving the stability of the device during operation.

[0044] In order to improve the stability during the adjustment process, four support rods 35 are fixedly connected to the outer wall of the circular frame 6 at equal distances, and limiting grooves 36 are provided on the inner side of the detection chassis 1 at positions corresponding to the four support rods 35, and the side walls of the support rods 35 are fixedly connected with limiting blocks 37 for sliding inside the limiting grooves 36;

[0045] The arrangement of the limiting block 37 and the limiting groove 36 can not only limit the circular frame 6 , but also drive the limiting block 37 to slide inside the limiting groove 36 when the electric telescopic cylinder 26 is driven.
