[0023] When in use, first put the wheel hub on the outside of the support plate 407, then you can control the motor 401 to rotate, then the motor 401 will drive the rotating rod 402 to rotate, and at the same time the movable block will gradually move inward under the action of the thread, then the movable block will drive the support plate 407 to expand outward through the connecting rod 2 406, then the support plate 407 will support the axis of the wheel hub, thereafter, as the motor 401 rotates, the rotating rod 402 will drive the entire fixing mechanism 4 to rotate through the connecting rod, and the wheel hub will also rotate accordingly, at this time the personnel can use external instruments to detect the balance of the wheel hub, by means of the rotating rod 402 in conjunction with the movable block and the connecting rod, the support plate 407 can be fixed to the axis of the wheel hub, thereby preventing the wheel hub from being offset due to gravity when the wheel hub is tested, and at the same time by fixing the mechanism The structure 4 can drive the wheel hub to rotate, so as to detect the balance of the wheel hub, so as to improve the practicality of the equipment. When it is necessary to detect the strength of the wheel hub, the cylinder 502 can be controlled to extend outward a part of the way, so that the extrusion plate 505 is close to the outer wall of the wheel hub. At this time, the fixing mechanism 4 can be controlled to release the fixation, so as to prevent the fixing mechanism 4 from being damaged during the extrusion process. Thereafter, the cylinder 502 can be controlled to extend, so as to push the extrusion plate 505 to apply pressure to the wheel hub. At this time, the personnel can detect the maximum pressure that the wheel hub can withstand by observing the pressure data of the cylinder 502, and apply pressure to the outer wall of the wheel hub through the extrusion mechanism 5, so as to detect the maximum force that the wheel hub can withstand when in use. At the same time, it can be detected through the arc-shaped extrusion plate 505, so that multiple surfaces of the wheel hub can be pressed synchronously, thereby improving the accuracy of the detection data.

[0024] like Figure 3As shown, the fixing mechanism 4 includes a motor 401, a rotating rod 402, a sleeve 403, a movable plate 404, a connecting rod 1 405, a connecting rod 2 406 and a support plate 407. The output end of the motor 401 is fixedly connected to the axis of the rotating rod 402, the rotating rod 402 is rotatably connected to the inside of the sleeve 403, and one end of the rotating rod 402 extends to the outside of the sleeve 403, one end of the connecting rod 1 405 is hinged to the outer wall of the sleeve 403, and the other end of the connecting rod 1 405 is hinged to the inner wall of the support plate 407. Wall, one end of the connecting rod 406 is hinged to the inside of the movable plate 404, and the other end of the connecting rod 406 is hinged to the inner wall of the support plate 407, one end of the rotating rod 402 is provided with a thread, and the movable plate 404 is threadedly connected to one end of the rotating rod 402, one end of the sleeve 403 is rotatably connected to the outer wall of the connecting plate 6, one end of the rotating rod 402 is movably connected to the top end of the support rod 3, the fixed end of the motor 401 is fixedly connected to the outer wall of the connecting plate 6, and the output end of the motor 401 passes through the connecting plate 6.

[0025] First, after the wheel hub is sleeved on the outside of the support plate 407, the motor 401 can be controlled to rotate. At this time, the motor 401 will drive the rotating rod 402 to rotate, and the movable block will gradually move inward under the action of the thread. At this time, the movable block will drive the support plate 407 to expand outward through the connecting rod 406. At this time, the support plate 407 will support the axis of the wheel hub. Thereafter, as the motor 401 rotates, the rotating rod 402 will drive the entire fixing mechanism 4 to rotate through the connecting rod, and the wheel hub will also rotate accordingly. At this time, the personnel can use external instruments to detect the balance of the wheel hub. The rotating rod 402 cooperates with the movable block and the connecting rod to fix the support plate 407 to the axis of the wheel hub, thereby preventing the wheel hub from being offset due to gravity when the wheel hub is tested. At the same time, the wheel hub can be driven to rotate through the fixing mechanism 4 to detect the balance of the wheel hub, thereby improving the practicality of the equipment.

[0026] like Figure 2-4 As shown, the extrusion mechanism 5 includes a fixed column 501, a cylinder 502, a guide rod 503, a spring 504 and an extrusion plate 505, the output end of the cylinder 502 is fixedly connected to the outer wall of the extrusion plate 505, and the fixed end of the cylinder 502 is fixedly connected to the top of the fixed column 501, one end of the guide rod 503 is fixedly connected to the outer wall of the extrusion plate 505, and the other end of the guide rod 503 is movably connected to the inside of the fixed column 501, one end of the spring 504 is fixedly connected to the outer wall of the extrusion plate 505, and the other end of the spring 504 is fixedly connected to one side of the top of the fixed column 501, the guide rod 503 is movably connected to the opposite side of the spring 504, and the bottom end of the fixed column 501 is fixedly connected to the top of the operating table 1.

[0027] When it is necessary to detect the strength of the wheel hub, the cylinder 502 can be controlled to extend a part outward first, so that the extrusion plate 505 is close to the outer wall of the wheel hub. At this time, the fixing mechanism 4 can be controlled to release the fixation, thereby preventing the fixing mechanism 4 from being damaged during the extrusion process. Thereafter, the cylinder 502 can be controlled to extend, so that it pushes the extrusion plate 505 to apply pressure to the wheel hub. At this time, personnel can detect the maximum pressure that the wheel hub can withstand by observing the pressure data of the cylinder 502, and apply pressure to the outer wall of the wheel hub through the extrusion mechanism 5, so as to detect the maximum force that the wheel hub can withstand when in use. At the same time, it can be detected through the arc-shaped extrusion plate 505, so that multiple surfaces of the wheel hub can be pressurized synchronously, thereby improving the accuracy of the detection data.

[0028] Here’s how it works:

[0029] First, after the wheel hub is sleeved on the outside of the support plate 407, the motor 401 can be controlled to rotate. At this time, the motor 401 will drive the rotating rod 402 to rotate. At the same time, the movable block will gradually move inward under the action of the thread. At this time, the movable block will drive the support plate 407 to expand outward through the connecting rod 2 406. At this time, the support plate 407 will support the axis of the wheel hub. Thereafter, as the motor 401 rotates, the rotating rod 402 will drive the entire fixing mechanism 4 to rotate through the connecting rod. At this time, the wheel hub will also rotate accordingly. At this time, the personnel can use external instruments to detect the balance of the wheel hub. The rod can fix the support plate 407 to the axis of the wheel hub. When the strength of the wheel hub needs to be tested, the cylinder 502 can be controlled to extend outward a part so that the extrusion plate 505 is close to the outer wall of the wheel hub. At this time, the fixing mechanism 4 can be controlled to release the fixation, thereby preventing the fixing mechanism 4 from being damaged during the extrusion process. Thereafter, the cylinder 502 can be controlled to extend so that it pushes the extrusion plate 505 to apply pressure to the wheel hub. At this time, personnel can detect the maximum pressure that the wheel hub can withstand by observing the pressure data of the cylinder 502, and apply pressure to the outer wall of the wheel hub through the extrusion mechanism 5, thereby detecting the maximum force that the wheel hub can withstand when in use.
