摘要： A device for aligning a first and a second shell mold comprises a first gripper for holding the first shell mold, a second gripper for holding the second shell mold, and a centering station. Both grippers can be displaced relative to one another and relative to the centering station along a predetermined axis and can rotate individually as well as synchronously about the axis. The centering station comprises a supporting body, which supports spring elements arranged along a circle, said axis running through the center of the circle. For centering, the shell mold is moved into the centering station by the gripper and then removed from the gripper so that the shell mold is held solely by the spring elements. The radial forces of the spring elements uniformly acting upon the shell mold from all sides cause the shell mold to be displaced into the center of gravity of the forces. Afterwards, the shell mold is gripped once again by the gripper and moved out from the centering station.
摘要翻译：用于对准第一和第二壳模的装置包括用于保持第一壳模的第一夹持器，用于保持第二壳模的第二夹持器和定心台。两个夹具可以相对于彼此并且相对于定心站沿着预定轴线移位，并且可以单独旋转并且围绕轴线同步地旋转。定心台包括支撑体，该支撑体支撑沿着圆周布置的弹簧元件，所述轴线穿过圆的中心。为了对中，壳模通过夹具移动到定心站中，然后从夹具移除，使得壳模仅由弹簧元件保持。均匀地作用在壳模上的弹簧元件的径向力使得壳模移动到力的重心上。之后，通过夹持器再次夹住壳模，并从定心台移出。
