Tool structure for assembling wing inner framework

The tool structure comprises a main frame body, a limiting groove is formed in the middle of the top face of a top plate of the main frame body, a to-be-machined wing shell is inserted into the limiting groove, the outer side wall of the wing shell is tightly attached to the inner side wall of the limiting groove, and a plurality of reinforcing rib pieces are inserted into the wing shell in a sleeved mode; a triangular supporting shell is installed in the rear portion of the middle of the wing shell, and the triangular supporting shell and the bottom faces of all the reinforcing rib pieces are fixed to the top face of a bottom plate of the wing shell in an adhesive mode through an adhesive. The supporting rod can move along the transverse guide rail, so that the supporting position of the hemispheroid is changed, it is guaranteed that the supporting rod can accurately support and position the position, opposite to the transverse reinforcing rib, of the middle reinforcing rib, the top plate of the main frame b
