Abstract

The invention discloses a positioning tool and a positioning method for a resin film melt permeation molding stiffened plate, the positioning tool comprises a positioning clamping plate and a plurality of horseshoe-shaped positioning clamping pieces, and the positioning clamping plate is provided with a plurality of positioning grooves for rib positioning; each horseshoe-shaped positioning clamping piece is arranged in each positioning groove, and a second positioning groove for positioning the soft film is formed in each positioning groove; the rib and the soft film are accurately positioned through the positioning groove and the second positioning groove, and a heavy rib forming die is not adopted any more; meanwhile, fine adjustment of the positions of the ribs is achieved through the gravity of the positioning clamping plate, and compared with a traditional adjustment mode, pushing force borne by the ribs is softer, and the ribs are prevented from being damaged; after the ribs are attached to the inner wall of the whole positioning groove, stress of the ribs is offset, so that acting force borne by the ribs is automatically balanced at the adjusted tail end, intervention of workers is not needed, complex automatic control programs are not needed either, the adjusting process is simple, and the positioning efficiency is improved.

Description

technical field

[0001] The application relates to the technical field of positioning equipment, in particular to a positioning tool and a positioning method for a resin film fusion infiltration molding stiffened plate. Background technique

[0002] Stitching technology is a Z-direction reinforcement technology for composite materials, which can improve the interlayer shear performance of composite materials. Resin film fusion infiltration (RFI for short) is a typical low-cost manufacturing technology for composite materials. Large-scale composite materials are formed by stitching + RFI technology. Composite hat-shaped reinforced wall panels are widely used at home and abroad.

[0003] In the prior art, before suturing, it is necessary to accurately position the hat-shaped ribs on the skin to facilitate subsequent suturing, and at the same time use a ring-shaped closed rubber soft mold to support the uncured ribs; but for large-scale reinforced wall panels, the Rib forming m...
