The invention provides a large-stroke precise alignment platform and belongs to the technical field of machinery. The technical problem that a movable platform of an existing precise alignment platform is small is solved. The large-stroke precise alignment platform comprises a movable platform and a fixed base, the fixed base is annular, the top of the fixed base is in sliding connection with a plurality of chucks capable of being rotated in the circumferential direction of the fixed base, guide rails are fixed on the chucks, sliding blocks are in sliding connection with the guide rails, shaftrings are rotationally connected to the tops of the sliding blocks, the tops of the sliding blocks are sleeved with the shaft rings correspondingly, and the shaft rings are rotationally connected with the movable platform. By means of the alignment platform, the movable platform can be translated and rotated in a large range, the working space is larger, and alignment is more accurate. 本发明提供了一种大行程精密对位平台，属于机械技术领域。它解决了现有精密
