However, this production line cannot achieve automation in the loading and unloading parts, and a lot of manual labor is required to transport the workpiece until the wheel blank reaches the processing position. Product performance becomes unstable, affecting production efficiency. The prior art further disclosed an automobile wheel production line, which includes a bottom frame, a side frame, a laying frame, and a reel, and its structure is simple, which can effectively prevent wheel product damage and improve the product acceptance rate. . However, the stacking process in this production line cannot accurately position the wheel workpieces, and the stacking of workpieces is easy to interfere, causing workpiece wear, increasing the defective rate, and production safety is not guaranteed. Can not.

In the prior art, the loading table further includes a circular turntable and a power unit, and three lathes are installed for processing the wheel, and the manipulator sends the wheel processed by the lathe system to the unloading device. disclosed a loading table and wheel processing system. However, since the workpieces to be machined on the loading table of this system cannot be automatically replenished, the continuity of machining cannot be guaranteed, and the machining process is set across three lathes, so the workpieces cannot be clamped. The number of times is large, which affects machining accuracy.

In summary, the layout of the processing part of the existing automobile wheel production line is insufficient, it occupies a large space, and there are problems such as the large deviation of the clamp positioning device.
