The utility model relates to the technical field of high-precision positioning platforms, in particular to a high-precision positioning platform for die
machining. Comprising a base, a connecting seat, a limiting frame, a
machining table, a filter screen, electric sliding rails I and electric sliding blocks I. The limiting frame is fixedly connected to the base, the connecting seat is arranged in the limiting frame in a sliding mode, the
machining table is installed on the connecting seat, the filter screen is installed in the machining table, the two electric sliding rails I are installed in the machining table, and the electric sliding rails I are located above the filter screen. A scale plate I is mounted on the electric sliding rail I, and an electric sliding block I is mounted on the electric sliding rail I; by rotating a
threaded rod, a connecting plate drives a supporting frame and an electric fan to move upwards, when the electric fan is located above the filter screen, two
electric control sliding rails are started, the
electric control sliding rails drive
electric control sliding blocks on the electric control sliding rails to move leftwards, meanwhile, the electric fan is started, and therefore chippings on the filter screen can be automatically blown into a collecting frame; and the situation that the surface of the mold is scratched due to residual
metal chippings or
cutting fluid, and the appearance and functions are affected is avoided.
