Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] Such as Figure 1-5 As shown, the present invention provides a technical solution: a special positioning and clamping device for aircraft skins, including a molded tire 1 and a vacuum sealing structure 2 and a quick pressing member 3 arranged on the molded tire 1 .
[0029] The top surface of the molded tire 1 is provided with a concave arc surface, which is the same as the curvature of the aircraft skin to be processed, so that the molded...

The invention provides a special positioning and clamping device for aircraft skin, which comprises a mould, a vacuumizing sealing strip, an auxiliary pressure applying mechanism and a quick pressing piece, and a vacuumizing sealing structure is arranged in the arc-shaped surface of the mould; the vacuumizing sealing structure comprises a sealing strip groove and six vacuumizing areas, and the multiple quick pressing pieces are fixed to the two sides of the sealing strip groove in the long axis direction of the top face of the mold body respectively. When the device is used, an aircraft skin to be machined is hoisted to the mold and pre-positioned, the auxiliary pressure applying mechanism is moved to a preset area according to a preset program to assist in applying pressure, meanwhile, partitioned vacuumizing operation is conducted, after vacuumizing, the aircraft skin is in large-area contact with the strip-shaped contact face of the skin mold, only the vacuumizing strip-shaped air groove is not in contact, and the vacuumizing strip-shaped air groove is not in contact with the skin mold. And then the periphery of the edge of the aircraft skin is tightly pressed through the rapid pressing pieces arranged on the die tire to guarantee sealing, so that aircraft skin machining operation can be carried out, and convenience and practicability are achieved.
Description
technical field [0001] The invention belongs to the technical field of aircraft skin processing devices, and in particular relates to a special positioning and clamping device for aircraft skins. Background technique [0002] After the aircraft skin is subjected to aerodynamic action, the force is transmitted to the connected fuselage and wing frame. The force is complex, and the skin is in direct contact with the outside world. Therefore, not only the skin material is required to have high strength and good plasticity, but also a smooth surface. , have higher corrosion resistance. [0003] In the field of aircraft hyperbolic large skin milling, large-scale skin positioning tooling mostly adopts a dot-matrix support positioning method, the support surface is small, and flutter is prone to occur during processing, and most mold tooling cannot be reused, and the tooling cost is high. Affect the efficiency of aircraft skin processing. Contents of the invention [0004] The ...
