[0002] Although today's automobile production has reached a sound level, it will take a long time to completely replace manual operations such as measurement and positioning. The wheel hub is an important part of the car, and the aluminum alloy wheel hub is popular for its beautiful appearance and light weight. Among them, the processing of forged aluminum alloy wheels is complex and costly. In the production process of forged aluminum alloy wheels, it is usually necessary to upset the cylindrical bar first, and then proceed to subsequent processing after obtaining the preliminary blank. While the operation is extruding, the aluminum alloy round bar needs to be continuously rotated to ensure that the metallographic structure of the material is good. Therefore, it is necessary to ensure that the round bar is located at the geometric center of the rotation of the device before work. At present, the operation of this step is mostly Manually, a mechanism is needed to solve the problem of adapting to the clamping when the centering and diameter change

The invention discloses a clamping and fixing mechanism for aluminum alloy wheel hub forging production, which includes an upsetting machine frame, a lower turntable mechanism, an upper turntable mechanism, and aluminum alloy round bars. The upsetting machine frame is a working platform for carrying and driving the entire mechanism , The lower turntable mechanism is used for centering operation when upsetting the round bar, and the upper turntable mechanism is used for clamping and fixing the aluminum alloy round bar while directly changing during the upsetting process. The manual centering operation of the round bar during upsetting is eliminated, and the center of rotation of the processed hub is guaranteed to be its geometric center.
