Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of composite material assembly, in particular to a correction tool for misaligned holes in the assembly of composite material products. Background Technique
[0002] Affected by uneven composition distribution of reinforcing materials and matrix materials inside composite material products, generally, composite material products are prone to warping, deformation, etc. during long-term storage and use. When there are slight warping, deformation, etc., the impact on the performance and quality of the products is relatively small; however, it has an impact on products that need to be assembled together through assembly holes, and there will be a situation of misalignment of multiple hole positions, affecting the bolt installation at the hole positions of the products.
[0003] When solving the problem of hole position deviation during the assembly of composite material products, generally, methods such as prying bar extrusion, knocking correction, and hole repair correction are adopted; the deficiencies of the above correction methods are as follows:
[0004] 1. Prying bar extrusion: By using a special prying bar, inserting it into the corresponding bolt connection hole, correcting the deviated hole position, and then performing bolt connection installation. This method is prone to cause extrusion damage at the hole position of the product, and the hole position correction is inaccurate, and the assembly difficulty is relatively large.
[0005] 2. Knocking correction: Placing the connecting bolt in the deviated hole position, and using tools such as a hammer head to knock, forcing the bolt to penetrate into the connecting hole, and then tightening the bolt. This method is barbaric and rough, does not meet the conventional requirements, is extremely prone to causing damage to multiple parts of the product, and has relatively large potential hazards in the later stage.
[0006] 3. Hole repair correction: By using a grinding tool to ream the hole or reprocess, eccentric reaming or uniform reaming by reprocessing on the original hole position to remove the interfering part, and then using bolt connection. This operation is only applicable to the correction of a single hole position deviation. If it is used to correct the deviation of multiple hole positions, it will cause waste of working hours; at the same time, the gap between the reamed hole position and the bolt increases, and it is easy to have a misalignment situation at the mating part of the product in the later stage.

The correction tension rod 5 is fixed on the tooling bottom plate 2 through the bolts 3. A jack 10 slidably connected to the tooling bottom plate 2 is arranged at the rear side of the correction tension rod 5. With the jack structure, the operation is simple and labor-saving, and the operator can quickly get started, improving the assembly efficiency. A rubber pad 9 is fixed at the telescopic end of the jack 10. A rubber pad is added at the contact part with the product to avoid damaging the product. For the jacking structure, the jack 10 is placed on the tooling bottom plate 2 and locked and fixed through the jack fixing flange nut 1. Then the end of the rubber pad 9 is fixed at the jacking position of the jack 10. Two U-shaped groove through holes symmetrically arranged front and back are formed on the tooling bottom plate 2. A flange nut 1 is fixed at the right end of the jack 10. The jack 10 is fixed in the U-shaped groove through hole of the tooling bottom plate 2 through the flange nut 1. The flange nut 1 guides and fixes the jack 10. In the connection between the tooling bottom plate 2 and the jack 10, a U-shaped groove through hole structure is adopted, and there are fine adjustment structures in both the left-right and up-down directions, which is applicable to the correction of hole position deviations of different sizes and shapes and has strong versatility. A jacking adjustment bolt 7 is threadedly connected to the left end of the correction tension rod 5. A correction positioning pin 8 is slidably connected to the left end of the correction tension rod 5. For the correction positioning structure, the correction tension rod 5 is fixed on the tooling bottom plate 2 through the bolts 3 and locked. Then the reinforcing diagonal brace 4 is placed at the reserved reinforcing position of the correction tension rod 5 and locked and fixed with the bolts 3. Then the correction positioning pin 8 is inserted into the side fixing hole of the correction tension rod 5 and locked with the positioning pin fixing nut 6. At the same time, the jacking adjustment bolt 7 is installed at the top end of the correction tension rod 5. A positioning pin fixing nut 6 is threadedly connected to the front end of the correction positioning pin 8. A handle 11 is fixed at the upper end of the tooling bottom plate 2.
