[0029] A first casting clamp 20 is arranged above one side of the rotating platform for loading a casting and allowing a part of the head of the casting to be cut off;
[0030] A second casting clamp 30 is arranged above the other side of the rotating platform for loading a casting and allowing another part of the head of the casting to be cut off;
[0031] A ejector pin 40 is driven by a lifting drive (not shown) for pressing the casting loaded on the first casting clamp and the second casting clamp (the ejector pin and the lifting drive assembly are installed on the automatic cutting machine in the implementation and combined with other parts of the present application to form a positioning tool).
[0032] In the specific implementation, the operator first loads the A casting to be processed on the first casting clamp and drives the rotating platform to rotate to the automatic cutting machine position. When the first casting clamp is at the automatic cutting machine position, the lifting drive drives the ejector pin to press the A casting. Then the automatic cutting machine automatically cuts the head of the A casting.
[0033] In this process, the second casting clamp is at the loading position. At this time, the operator does not load a casting on the second casting clamp.
[0034] After the head of the A casting loaded on the first casting clamp is cut off by the automatic cutting machine, the rotating platform drives the first casting clamp and the second casting clamp to exchange positions. The second casting clamp is at the automatic cutting machine position. The automatic cutting machine and the lifting drive do not act. At this time, the operator loads the B casting to be cut on the first casting clamp.
[0035] When the first casting clamp loads the B casting, the rotating platform drives the first casting clamp and the second casting clamp to exchange positions. When the first casting clamp is at the automatic cutting machine position, the lifting drive drives the ejector pin to press the B casting. Then the automatic cutting machine automatically cuts the head of the B casting.
[0036] In this process, the operator loads the A casting on the second casting clamp.
[0037] After the first head of the B casting is cut off by the automatic cutting machine and the rotating platform drives the first casting clamp and the second casting to exchange positions again, the lifting drive drives the ejector pin to press the A casting. The automatic cutting machine automatically cuts the other head of the A casting. In this process, the operator needs to put the C casting to be processed on the first casting clamp. This cyclic operation can continuously cut the heads of other castings to be processed.
