A parallel type macro-micro driven raster splicing device with high precision and big caliber relates to a raster splicing device with high precision and big caliber. The invention can solve the problem that China has no raster splicing devices with high precision and big caliber. A two-dimensional moving platform part (7) is fixed on a base (6); the lower end of a movable raster part (1) is hinged with the upper end of the two-dimensional moving platform part (7); a fixed raster part (4) is fixedly arranged on the base (6); a first X-axle linear driver (2), a third X-axle linear driver (9) and a second X-axle linear driver (8) are arranged on the base (6) from top to bottom along the direction of an X-axle in turn; each linear driver is respectively fixedly connected with the base (6) and the raster part (1). The invention has the advantages of compact structure, convenient adjusting, flexible operation and high splicing precision, etc., and can realize the splicing with high precision in five space free directions of the movable raster and a static raster in a large area.
