Embodiment approach 1

[0040] as attached figure 1 As shown, it is the positioning principle of large-scale hat-shaped reinforced wall panels in the prior art. There are positioning holes on the top of the rib forming mold, and corresponding supporting screws are provided on the gantry. The supporting screws are inserted into the positioning holes to The rib forming mold is fixed, so it is necessary to constantly adjust the position of the rib forming mold in the process of rib positioning to make all the positions of the gantry. The weight of the rib forming mold is as high as 100 kg, and it is hoisted by a crane. The construction time It takes a long time to occupy the crane, consumes a lot of manpower and material resources, the assembly efficiency is low, and the position accuracy of the ribs is not high, the bolt may be installed forcibly, and the accuracy of the position of the ribs seriously affects the stitching of the subsequent ribs and the final The rib position of the formed hat-shaped r...

Embodiment approach 2

[0048] like Figure 4 As shown, this embodiment, as a preferred embodiment of the present invention, discloses a positioning method for a positioning tool for a resin film melt infiltration molding stiffened plate, which is characterized in that it includes the following steps:

[0049] S1. Arrange the positioning clamps at the installation station in sequence along the axial direction of the ribs;

[0050] According to the positioning accuracy requirements and combined with the actual working conditions of the processing site, first determine the number of positioning clamps;

[0051] Combined with the position of the ribs at the rib assembly station, the shape parameters and position parameters of each positioning groove on the positioning ribs are calculated in advance, and the processing of the corresponding positioning ribs is completed. At the same time, the position of each positioning clamp is fixed, so for It is convenient to quickly and accurately install each posit...

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...
