The present invention provides a positioning device and a use method therefor. Multiple main frame supports are supported on the ground and arranged at intervals, and the main frame supports enclose to form a circle; the number of cross beams is the same as the number of the main frame supports, one ends of the cross beams are connected to the tops of corresponding main frame supports, and the other ends of the cross beams converge to the center point of the circle and are connected to each other, and a plane formed by connecting the multiple cross beams is used for placing an annular plate; a central disc is disposed above the center point of the circle; one planar steel plate is provided on the top of one corresponding main frame support; one protruding beveled steel plate is provided on one corresponding planar steel plate, and the protruding beveled steel plate is used for positioning the outer edge of the annular plate. The present invention can be used for solving the problem of a complex situation that an adjusted and positioned annular plate cannot meet a positioning requirement by means of a general method due to a large diameter, a heavy weight and high precision.
