[0003] When the existing forged wheel hub is tested for optical components, there is an initial fixed position. When the fixed position deviates, it is easy to affect the detection. The optical component needs to be repositioned, the wheel hub cannot be transported and positioned quickly, and it deviates under the action of centrifugal force during rotation, affecting the detection results. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an automobile wheel hub detection device based on an optical component, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automobile wheel hub detection device based on an optical component, comprising a detection platform, the inner cavity of the detection platform is rotatably provided with a long conveying roller and a short conveying roller for conveying the wheel hub, the inner cavity of the detection platform is fixedly connected with a receiving platform rotatably connected to the side of the short conveying roller, the inner cavity of the receiving platform is provided with a lifting column lifted by a hydraulic cylinder, the top of the lifting column is rotatably connected with an electromagnet moving seat embedded in the receiving platform through a motor drive, and the inner cavity of the electromagnet moving seat is provided with a positioning hole;

The wheel hub is transported on the long conveyor roller, and the motor drives the long conveyor roller to rotate and drive the wheel hub to the short conveyor roller until the center hole of the wheel hub is located below the positioning rod. At this time, the bottom of the wheel hub abuts against the ball bearings on the receiving platform and the surface of the auxiliary plate. At this time, the lifting rod is driven down by the lifting mechanism, and the lifting rod drives the connecting rod and the positioning rod to move downward. The positioning rod moves downward and passes through the center hole of the wheel hub and is inserted into the positioning hole in the electromagnet moving seat. At this time, the positioning rod abuts against the inner cavity of the center hole of the wheel hub, driving the ball bearings to roll on the ball bearings on the surface of the auxiliary plate, and roughly adjusts the position so that the center hole of the wheel hub is aligned with the positioning hole. Then, air is supplied to the pneumatic piston rod, and the four top plates extend toward the sides at the same time, and abut against the inner wall of the center hole of the wheel hub through the arc surface to adjust the position of the wheel hub. Because the pneumatic pressure is the same, the wheel hub can be accurately positioned. Then, the hydraulic cylinder drives the lifting column to rise, driving the electromagnet moving seat to rise and abut against the bottom of the wheel hub. Then, power is turned on to adsorb the wheel hub. At this time, the electromagnet moving seat and the lifting rod rise synchronously until the electromagnet moving seat moves to the top of the receiving platform.

After the detection is completed, the output is reset, which can effectively fix the wheel hub in the detection position to prevent the detection error caused by the deviation of the wheel hub position. The positioning is carried out through the steps of rough positioning first and then fine positioning, which makes the positioning faster and more accurate. Even if it rotates, the position of the wheel hub will not deviate under the action of centrifugal force.

When the wheel hub moves to above the electromagnet moving seat, the bottom of the wheel hub abuts against the ball, and the position of the wheel hub can be moved smoothly at this time.

[0010] As a further solution of the present invention: when the electromagnet moving seat is in the initial position, the tops of the long conveying roller, the short conveying roller and the ball are in the same horizontal plane, and the top of the receiving platform is lower than the surface of the short conveying roller. By setting the height difference, the wheel hub can be smoothly transported to the top of the receiving platform, and then the electromagnet moving seat is lifted to receive the wheel hub.

[0011] As a further solution of the present invention: an optical detection component for detecting the wheel hub is fixedly connected to one side of the frame, and the optical detection component includes a light source, a transmitting component, a receiving component and an imaging component.

[0012] As a further solution of the present invention: four auxiliary plates are provided and are evenly arranged on the surface of the electromagnet moving seat along the circular track of the wheel hub edge, so as to effectively support the wheel hub.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention can effectively fix the wheel hub at the detection position to prevent detection errors caused by wheel hub position deviation. The positioning is performed through the steps of rough positioning first and then fine positioning, so that the positioning is faster and more accurate.
