Embodiment 1

[0029] A surface processing method for honeycomb parts oriented to the serpentine ring core structure, such as Figure 4 As shown, it mainly includes the following steps:

[0030] Step S200: Based on the contour surface 3 of the formed part as a reference, the disc cutter 4 is selected to process the shape of the part in a manner of gradually removing material with a variable swing angle.

[0031] During the use of the present invention, the disc cutter 4 performs surface processing on the basis of the part contour surface 3, and the disc cutter 4 performs profile processing in a progressive manner with variable swing angles, and the profile processing includes successively processed α Shaped surface, β-shaped surface...γ-shaped surface; first, the disc cutter 4 forms an α angle 6 with the root of the part contour surface 3 and processes it, and the processing is in place to form an α-shaped surface; the disc cutter 4 along the part contour surface 3 The root forms a β angle 7 ...

Embodiment 2

[0034] This embodiment is further optimized on the basis of embodiment 1, as image 3 As shown, the cutting method of the disc cutter 4 in the step S200 is down milling, and the position of the cutter rotation reversal does not exceed 1 / 2 of the front and rear boundaries of the part. The present invention adopts the mode of down-milling to process profile by disc cutter 4, guarantees that the processing profile of the honeycomb part 1 of serpentine ring cell structure has high quality; Exceeding 1 / 2 of the front and rear boundaries of the part, the processed surface has higher precision and improves the quality of the 4-pair surface processing of the disc cutter.

[0035] Other parts of this embodiment are the same as those of Embodiment 1, so details are not repeated here.

Embodiment 3

[0037] This embodiment is further optimized on the basis of Embodiment 2. The position of the tool rotation reversal of the disc cutter does not exceed 1 / 3 of the front and rear boundaries of the part. The further limitation of the position of the rotation and reversing of the disc cutter 4 makes the processing of the profile more precise and makes the processed honeycomb part 1 more precise.

[0038] Other parts of this embodiment are the same as those of Embodiment 2, and will not be repeated here.

Abstract

The invention discloses a honeycomb part profile processing method facing a serpentine ring core lattice structure, which mainly includes step S200: based on the formed part profile surface as a benchmark, a disc cutter is selected, and the material is gradually removed with a variable swing angle. way to process the part surface. The invention uses a disc cutter to change the swing angle of the honeycomb parts with the serpentine ring core lattice structure to perform profile machining on the contour surface of the part, which effectively solves the problem that the honeycomb parts with the serpentine ring core lattice structure are processed on the profile surface. The phenomenon of core lattice tearing, lack of meat, and scrapping occurs when the core lattice is torn, which improves the processing quality of the honeycomb parts with the serpentine ring core lattice structure, improves the processing efficiency, and reduces the processing cost.

Description

technical field [0001] The invention belongs to the technical field of processing honeycomb parts with a serpentine ring cell structure, and in particular relates to a surface processing method for a honeycomb part facing a serpentine ring cell structure. Background technique [0002] Intelligent deformable aircraft can achieve higher aerodynamic efficiency by changing its shape, which has become an important development direction of aerospace vehicles. The traditional skin maintains the shape of the aircraft, directly bears the aerodynamic load and transmits it to the internal horizontal and vertical stress members of the aircraft, and at the same time bears the corresponding bending moment and shear force when the wing deforms. With the development of deformable aircraft, some new requirements have been put forward for the aircraft wing skin, which not only needs to have a low in-plane modulus in a specific direction to save deformation energy, but also have a higher load ...
