Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a four-wheel alignment camber adjustment structure, including a base 1 for connecting various components. On the left and right sides of the top surface of the base 1, cylinders 2 are fixedly connected for adjusting the height of the top plate 3. The tops of the two cylinders 2 are jointly fixedly connected with a top plate 3 for cooperating with the installation of the motor 7. The bottom surface of the top plate 3 is fixedly connected with a motor 7 for adjusting the angles of the clamping assembly 5 and the fixing assembly 6, thereby adjusting the camber of the wheel. An installation frame 4 is arranged on the upper part of the top plate 3 for cooperating with the installation between the clamping assembly 5 and the fixing assembly 6. A clamping assembly 5 is arranged at the front of the installation frame 4 for fixing the wheel. A fixing assembly 6 is arranged at the rear of the clamping assembly 5 for controlling the fixing block 531 on the connecting rod 53 to fix the wheel hub.

[0032] Furthermore, the installation frame 4 includes a bottom plate 41 for connecting various components. A vertical plate 43 is fixedly connected to the front part of the top surface of the bottom plate 41 for cooperating with the installation and adjustment of the clamping assembly 5. A connecting plate 42 is fixedly connected to the rear part of the top surface of the bottom plate 41 for cooperating with the installation of the fixing assembly 6.

[0033] Even further, the output end of the motor 7 is fixedly connected with a connecting shaft 71 for cooperating with the connection of the bottom plate 41. The connecting shaft 71 penetrates through the top plate 3 and is rotatably connected thereto. The top of the connecting shaft 71 is fixedly connected with the bottom plate 41.

[0034] As Figure 4 shown, the clamping assembly 5 includes a circular plate 51 for connecting various components. A screw rod 58 is rotatably connected to the middle of the circular plate 51 for adjusting the position of the circular plate 51. The screw rod 58 penetrates through the vertical plate 43 and is threadedly connected thereto. Control plates 52 are fixedly connected to the left and right sides of the outer wall of the circular plate 51 for cooperating with the connection of the connecting rod 53. A connecting rod 53 is arranged in the middle of the control plate 52 for the connection between the fixing assembly 6 and the clamping assembly 5. A control opening 521 is provided in the middle of the control plate 52 for cooperating with the movement and connection of the connecting rod 53. The connecting rod 53 is slidably connected thereto. A fixing block 531 is fixedly connected to the front end of the connecting rod 53 for fixing the wheel hub. Struts 55 are arranged between the two control plates 52 and the vertical plate 43 for cooperating with the connection between various components. Installation blocks 57 are movably connected to the ends of the two struts 55 close to the vertical plate 43 for cooperating with the installation of the struts 55. The installation blocks 57 are fixedly connected to the vertical plate 43. A limiting block 56 is movably connected to the middle of the end of the strut 55 close to the control plate 52 for cooperating with the connection of the connecting rod 53. The connecting rod 53 penetrates through the limiting block 56 and is movably connected thereto.

[0035] Further, the fixing component 6 includes an adjusting plate 61 for cooperating to adjust the distance between the adjusting fixing block 531 and the control board 52. The screw rod 58 passes through the adjusting plate 61 and is movably connected thereto. A hollow tube 62 is rotatably connected to the rear part of the adjusting plate 61, and the middle part thereof is hollow. The hollow tube 62 passes through the connecting plate 42 and is threadedly connected thereto for driving the adjusting plate 61 to adjust its position. Slide grooves 63 are formed in the left and right parts of the front side of the adjusting plate 61 for cooperating with the connection and movement of the connecting rod 53. The rear part of the connecting rod 53 is slidably connected thereto.

[0036] Working principle: When in use, first, the air cylinder 2 is opened according to the size of the wheel, so that it drives the top plate 3, the mounting bracket 4, the clamping component 5 and the fixing component 6 on the top plate 3 to change in height to adapt to wheels of different sizes. Then, the screw rod 58 is rotated according to the size of the wheel. The screw rod 58 will drive the circular plate 51 to move accordingly, and the control board 52 connected to the circular plate 51 will move accordingly. When the position of the control board 52 changes, the connecting rod 53 will move accordingly. Since the connecting rod 53 is connected to the support rod 55, and one side of the support rod 55 is connected to the vertical plate 43 through the mounting block 57, when the position of the control board 52 changes, the connecting rod 53 will slide in the control port 521. After the two sides of the wheel are clamped by the connecting rod 53, the rotation of the screw rod 58 can be stopped. Then, the hollow tube 62 is rotated to drive the adjusting plate 61 to move in position. When the position of the adjusting plate 61 changes, the connecting rod 53 connected thereto through the slide groove 63 will be driven by it to move in position until the fixing block 531 fixes the wheel hub. Then, the motor 7 is turned on, and it drives the mounting bracket 4 to rotate through the connecting shaft 71, so as to adjust the inclination angle of the wheel. After the adjustment is completed, first rotate the hollow tube 62 in the reverse direction to drive the fixing block 531 to release the wheel hub, and then rotate the screw rod 58 in the reverse direction to release the wheel by the two connecting rods 53.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent substitution on some of the technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
