[0021] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5, the present utility model provides a technical solution: an automobile wheel hub testing tooling, including: a testing tooling base 1, a detection component 7. A bracket 4 is fixed at the top of the testing tooling base 1, and a first cylinder 5 is installed below the bracket 4. A vertical plate 3 is fixed at the top of the testing tooling base 1. After the automobile wheel hub is placed on the testing tooling base 1, the first cylinder 5 is started. The expansion of the first cylinder 5 pushes part of the rotating component 2 downward. At this time, with the cooperation of the rotating component 2 and the first cylinder 5, the automobile wheel hub to be tested placed on the testing tooling base 1 can be subjected to stamping treatment. When the automobile wheel hub is unqualified, that is, of poor quality, it will have a serious deformation problem after being impacted. The detection component 7 is arranged at the top of the testing tooling base 1. The detection component 7 includes a camera 71 installed on the vertical plate 3, a second cylinder 72 installed at the top of the testing tooling base 1, a second moving plate 73 installed at the rod end of the second cylinder 72, a second guide rod 75 passing through the second moving plate 73, a U-shaped frame 74 fixed at one end of the second guide rod 75, and a roller 76 rotatably installed in the U-shaped frame 74. The detection component 7 is used to detect the deformation degree of the automobile wheel hub. The detection component 7 further includes a second spring 77 fixed between the U-shaped frame 74 and the second moving plate 73, and the second spring 77 is outside the second guide rod 75. Start the second cylinder 72 to move the roller 76 towards the automobile wheel hub after testing. At this time, the roller 76 contacts the automobile wheel hub. Since there is a second spring 77 between the U-shaped frame 74 and the second moving plate 73, the U-shaped frame 74 can be reset by the action of the second spring 77. Since the roller 76 is squeezed by the automobile wheel hub around its circumference, after the roller 76 is squeezed by the automobile wheel hub, the position of the second guide rod 75 will change. At this time, the second guide rod 75 is observed corresponding to the vertical color bar on the second moving plate 73, so as to judge whether the automobile wheel hub passing the impact test meets the qualified standard. The camera 71 is used to photograph the second guide rod 75, and the photographed image is transmitted to the display.

[0023] An automobile wheel hub testing tooling further includes a rotating component 2. The rotating component 2 is arranged on the testing tooling base 1. The rotating component 2 includes a bearing turntable 22 rotatably embedded at the top of the testing tooling base 1, a first driving motor 23 installed at the inner top of the testing tooling base 1 and driving the bearing turntable 22 to rotate, and an impact rotating disc 21 rotatably installed at the rod end of the first cylinder 5. When the impact rotating disc 21 contacts the upper surface of the automobile wheel hub, start the first driving motor 23. The output shaft of the first driving motor 23 drives the bearing turntable 22 to rotate. Since the bearing turntable 22 and the impact rotating disc 21 move the automobile wheel hub, the automobile wheel hub starts to rotate after being impacted and squeezed at this time.

[0024] An automotive wheel testing tooling further includes a clamping assembly 6. The clamping assembly 6 is disposed at the top end of the testing tooling base 1 and is used for clamping and fixing the automotive wheel. The clamping assembly 6 includes a bidirectional screw 61 rotatable at a position near the bottom end on the testing tooling base 1, a servo motor two 62 installed inside one side of the testing tooling base 1 by bolts and nuts and driving the bidirectional screw 61 to rotate, and a first moving plate 63 vertically inserted at the top end of the testing tooling base 1 and near both sides. The first moving plate 63 is in threaded connection with the bidirectional screw 61. The clamping assembly 6 further includes a first guide rod 64 horizontally penetrating through the first moving plate 63, an arc-shaped clamping plate 65 integrally welded and fixed to one side of the first guide rod 64, and a first spring 66 installed between the arc-shaped clamping plate 65 and the first moving plate 63. The two ends of the first spring 66 are respectively fixedly connected between the arc-shaped clamping plate 65 and the first moving plate 63, and the first spring 66 is located outside the first guide rod 64. First, after the automotive wheel to be tested is placed on the testing tooling base 1, the servo motor two 62 is started. The output shaft of the servo motor two 62 drives the bidirectional screw 61 to rotate. During the rotation of the bidirectional screw 61, the first moving plate 63 moves smoothly left and right. At this time, the two first moving plates 63 start to squeeze the automotive wheel, and the arc-shaped clamping plate 65 contacts the automotive wheel. Since a first spring 66 sleeved outside the first guide rod 64 is provided between the arc-shaped clamping plate 65 and the first moving plate 63, the buffer effect is achieved by the action of the first spring 66. Then, after the automotive wheel is impacted, the automotive wheel can be buffered, and thus the effect of deformation of the automotive wheel caused by over-tight clamping can be reduced.

[0025] Working principle: First, place the automotive wheel to be tested on the testing tooling base 1 and on the bearing turntable 22. Then, open the support 4. The support 4 expands and squeezes the impact rotating disc 21 towards the automotive wheel. After the extrusion, start the first driving motor 23. The output shaft of the first driving motor 23 drives the bearing turntable 22 to rotate. Through the extrusion of the bearing turntable 22, the automotive wheel is firmly squeezed. At this time, start the second cylinder 72. The second cylinder 72 expands and pushes the roller 76 towards a position close to the automotive wheel. However, when the output shaft of the first driving motor 23 rotates, the automotive wheel squeezes the roller 76, and the roller 76 contacts along the circumference of the automotive wheel. At this time, through the picture taken by the camera 71, detect the moving position of the second guide rod 75, and then it can be judged whether the automotive wheel is qualified or unqualified after passing the test.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
