[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-4, an automatic detection device for the outer peripheral wall of a hub ring of an automobile wheel hub, comprising a detection base 1 and a hub body 3, a detection bracket 2 is provided on one side of the top surface of the detection base 1, a power motor 4 is bolted to the bottom surface of the top of the detection bracket 2, a lifting seat 5 is bolted to the bottom surface of the lifting seat 5 with a second cylinder 7, a movable end of the second cylinder 7 is connected with a laser positioning head 8, a size detection component 6 is provided outside the laser positioning head 8, a telescopic adjustment component 9 is connected to one end of the lifting seat 5, an edge detection component 10 is connected to the bottom end of the telescopic adjustment component 9, a hub body 3 is provided on the top surface of the detection base 1, the vertical center line of the power motor 4, the vertical center line of the second cylinder 7, the vertical center line of the lifting seat 5 and the vertical center line of the laser positioning head 8 coincide with each other, and the entire device is mainly placed on the hub body 3 by manual or mechanical claws when it is actually used. The surface of the detection base 1 is used for processing. When placed, the laser positioning head 8 emits a vertical laser to correspond to the center position of the surface of the hub body 3, and keeps the vertical center of the hub body 3 and the vertical midline of the laser positioning head 8 coincident with each other. This part of the content can be calibrated and positioned manually or automatically by Jia Guang. After the hub body 3 is placed, the regularity of the surface circumferential size of the hub body 3 is first detected by the size detection component 6, and then adjusted by the telescopic adjustment component 9, and the edge detection component 10 is driven to perform circumferential detection of burrs on the surface of the hub body 3 and remove them after the burrs are detected. The entire device is automatically processed by the equipment, and the operator controls the telescopic amount of the cylinder of the entire device and the start and close of the motor through an externally connected controller, so as to realize the integrated processing of the surface size detection, burr detection and burr removal of the hub body 3.

[0027] When detecting the surface size of the hub body 3, since the size detection component 6 includes the first cylinder 601 and the detection ring 602, the two sides of the top surface of the detection ring 602 are bolted with mounting connecting plates 603, the movable end of the first cylinder 601 is bolted to the surface of the mounting connecting plate 603, the top surface of the first cylinder 601 is bolted to the two sides of the bottom surface of the lifting seat 5, and the inner wall of the detection ring 602 is bonded with an ultrasonic ranging patch 604, the mounting connecting plate 603 is used to connect the detection ring 602 and the first cylinder 601, and the inner wall of the detection ring 602 is used to measure the distance of the outer wall of the hub body 3 through the ultrasonic side specific patch, and the regularity and accuracy of the size of the surface of the hub body 3 are determined by comparing the difference in the distance measurement of each node. When it is used specifically, the movable end of the first cylinder 601 is extended to drive the detection ring 602 moves down to abut against the surface of the hub body 3 on the surface of the detection base 1 to cover the outer edge of the hub body 3. Since the hub body 3 and the laser positioning head 8 maintain vertical center overlap, the detection ring 602 maintains vertical center overlap with the laser positioning head 8 during installation. Therefore, after the detection ring 602 abuts against the hub body 3, the vertical centers of the hub body 3 remain overlapped with each other. Therefore, during theoretical detection, the ultrasonic ranging patch 604 measures the position of each node on the circumference of the surface of the hub body 3. In theory, the measured spacing of each node is the same, or the error is within a reasonable range. Therefore, by comparing the vertical differences of each node after measurement, the dimensional regularity of the surface of the hub body 3 is judged, thereby screening out hub bodies 3 of qualified sizes to achieve surface dimensional detection.

[0028] When the edge detection component 10 is adjusted and controlled, the telescopic adjustment component 9 is used for telescopic control. The telescopic adjustment component 9 includes a third cylinder 901 and a detection cylinder 903. The third cylinder 901 is embedded in one end of the lifting seat 5. The movable end of the third cylinder 901 is connected with an L-shaped connecting frame 902. The bottom surface of the bottom end of the L-shaped connecting frame 902 is bolted with a detection cylinder 903. The movable end of the detection cylinder 903 is connected to the edge detection component 10. The third cylinder 901 is extended, and the L-shaped connecting frame 902 drives the adjustment of the edge detection component 10 connected at the bottom, so as to facilitate the adaptive adjustment of the size radius of the surface of the hub body 3. The adjusted edge detection component 10 is against the surface of the hub body 3 to realize the contact detection of the surface of the hub body 3. The vertical height of the edge detection component 10 is adjusted by telescopic adjustment of the movable end of the detection cylinder 903, so as to facilitate the control of the detection component and the thickness of the hub body 3 to adapt to realize the contact detection processing.

[0029] When the entire device is used for edge detection component 10 detection, the specific structure is that the edge detection component 10 includes a guide motor 1001 and an L-shaped guide frame 1002. The top surface of the guide motor 1001 is threadedly connected to the movable end of the detection cylinder 903. The output shaft of the guide motor 1001 is connected to the intersection of the adjacent ends of the surface of the L-shaped guide frame 1002. A grinding cylinder 1004 and an ultrasonic detection head 1005 are respectively provided at both ends of the L-shaped guide frame 1002. The guide motor 1001 controls and adjusts the surface through the L-shaped guide frame 1002 to connect the grinding cylinder 1004 and the ultrasonic detection head 1005 to the surface of the hub body 3, thereby realizing burr detection on the surface of the hub body 3 and burr processing after detection. When burrs are detected on the surface of the hub body 3, the guide motor 1001 rotates 90 degrees to adjust the grinding cylinder 1004 to the surface of the hub body 3, thereby realizing grinding and eliminating the burr position.

[0030] When grinding and removing burrs on the surface of the hub body 3, an ultrasonic detection head 1005 is vertically engaged at one end of the L-shaped guide frame 1002, and a grinding motor 1003 is vertically provided on the top surface of the other end of the L-shaped guide frame 1002. The output shaft of the grinding motor 1003 penetrates the surface of the L-shaped guide frame 1002 and is screwed to the surface of the grinding cylinder 1004. The grinding motor 1003 drives the grinding cylinder 1004 to rotate to remove burrs from the surface of the hub body 3, and the ultrasonic detection head 1005 detects burrs on the surface of the hub body 3 through ultrasonic waves. Specific embodiment 2:

[0032] Reference Figure 1-4 In actual use, the size of the surface of the hub body 3 is first detected, and then the edge detection is performed by surface contact. After the size detection component 6 is detected, the movable end of the first cylinder 601 shrinks to the shortest distance, maintaining the minimum distance between the detection exchange and the lifting seat 5, preventing the detection ring 602 from blocking the use of the edge detection component 10. Specific embodiment three:

[0034] Reference Figure 1-4 ,The whole device uses the existing ultrasonic technology to detect the size and surface burrs. The detection principle is as follows:

[0035] When monitoring burrs, the ultrasonic detection head 1005 mainly includes a phased array ultrasonic host and a phased array probe, wherein the phased array probe is composed of multiple chips, and each chip forms an independent transmitting or receiving unit.

[0036] During the detection process, the phase relationship of each chip transmitting or receiving ultrasonic waves is changed by controlling the excitation delay time of each chip, so as to obtain the required sound beam. This technology can realize the control of the change of ultrasonic direction and focal depth. In non-destructive ultrasonic flaw detection, phased array technology will regard multiple chips as a group and excite them at the same time to form a virtual probe, and realize electronic scanning of the sound beam by exciting each virtual probe in turn.

[0037] For the detection of burrs on the hub surface, the ultrasonic phased array system works by sending an ultrasonic beam to the hub surface and receiving its reflected wave. If there are burrs on the surface of the hub body 3, the ultrasonic beam will be reflected at these uneven surfaces and received by the probe. By analyzing the characteristics of the reflected wave, such as amplitude, phase and frequency, it can be determined whether there are burrs on the hub surface and their position and size can be determined.

[0038] This detection method has the advantages of non-contact, high precision and high speed, and can realize efficient detection of burrs on the wheel hub surface. At the same time, the ultrasonic phased array system can also detect internal defects of the wheel hub, improving the quality and safety of the wheel hub.

[0039] When detecting the surface size of the hub body 3, the ultrasonic ranging patch 604 mainly relies on the reflection and propagation characteristics of ultrasonic waves. The following is the basic detection principle:

[0040] Transmitting ultrasonic waves: The ultrasonic probe transmits a beam of ultrasonic pulses to the surface of the wheel hub.

[0041] Ultrasonic propagation and reflection: Ultrasonic pulses propagate in the air or medium. When they encounter the surface of the wheel hub, part of the ultrasonic wave will be reflected back. Especially when the ultrasonic pulse encounters the edge of the wheel hub, the reflection of the ultrasonic wave will be particularly obvious due to the obvious physical interface changes at the edge.

[0042] Receiving reflected waves: The probe receives these reflected ultrasonic waves and converts them into electrical signals.

[0043] Calculate time difference: By analyzing the time difference between transmitting the ultrasonic pulse and receiving the reflected wave, the time required for the ultrasonic wave to propagate from the probe to the edge of the hub and return to the probe can be calculated. This time difference is related to the propagation speed of the ultrasonic wave in the medium.

[0044] Determine the distance: Since the propagation speed of ultrasound in the medium is known, the distance of ultrasound propagation can be calculated by the time difference and speed. Since ultrasound propagates in a straight line, this distance is the distance from the probe to the edge of the hub.

[0045] Data processing and display: Finally, the calculated distance values ​​can be processed and displayed through the data processing system for user reference.

[0046] It should be noted that in order to obtain accurate test results, the ultrasonic probe usually needs to maintain a certain angle and distance from the wheel surface to ensure that the ultrasonic wave can be correctly propagated and reflected. In addition, the impact of factors such as ambient temperature and medium properties on the ultrasonic propagation speed also needs to be considered during the test process.

[0047] In summary:

[0048] 1. The size and edge burrs on the surface of the hub body 3 are detected and removed by the size detection component 6 and the edge detection component 10 on the top of the detection base 1, and the center of the hub body 3 is positioned by the laser positioning head 8, so as to realize the integrated processing of the surface size and burr detection of the hub body 3, and use ultrasonic waves for distance measurement and detection, with accurate detection and high degree of automation, so as to facilitate the rapid automatic detection and processing of the outer periphery of the hub body 3 and improve the detection efficiency;

[0049] 2. The telescopic adjustment component 9 is used in conjunction with the edge detection component 10 to adjust the size. The edge detection component 10 detects the burrs on the outer periphery of the hub body 3 while the guide motor 1001 drives the L-shaped guide frame 1002 to rotate to perform contact processing on the grinding cylinder 1004. When the burrs on the surface of the hub body 3 are detected to be unqualified, synchronous removal and grinding processing is immediately performed to realize the detection and processing of the outer peripheral surface of the hub body 3, thereby reducing the occurrence of unqualified hub bodies 3 and improving the processing quality of the hub body 3.
