At this time, the pressure sensor 57 presses against the metal casting. The pressure on the casting is monitored in real time. When the pressure reaches the set threshold, drive motor 56 stops working, and drive motor 62 starts working. Drive motor 62 drives the pressure plate 64 along the adjusting frame 61 to clamp the metal casting on the upper side, so that the pressure plate 64 and the protective pad 65 are tightly fitted to the upper side of the metal casting.

At this time, the top of the positioning pin 67 is inserted into the positioning hole on the metal casting for stable positioning, thereby completing the positioning operation of the metal casting and enabling the metal casting to be processed stably.
