Special fixture used for stacking robot of continuous casting production line of aluminum ingots

The invention discloses a special fixture used for a stacking robot of a continuous casting production line of aluminum ingots. The special fixture is used for the stacking of molded aluminum ingots on a continuous casting production line of the aluminum ingots. A detecting cylinder (13) is fixed at the lower surface of a sole plate (12); a terminal end of a piston rod of the detecting cylinder (13) is provided with a detection disk (37); the whole fixture is connected with a robot through a connecting base (17); and after the aluminum ingots (78) are well arranged at ingot arrangement stations of a layer conveyor, the special fixture drops to a capturing position under the driving of the stacking robot, front and back clamping claws are closed under the action of a cylinder (73) and a cylinder (73) to clamp each ingot, and left and right ingot supporting claws support aluminum ingots outside an aluminum ingot layer under the action of a cylinder (38) and a cylinder (30).
