Abstract

The invention belongs to a numerical control processing technology of an airplane, and provides a machining method of a thin-wall curved surface type part. The machining method comprises the following steps: laying a soft leather cushion on a curved surface of a machined part; filling gypsum into the region on one side of the machined part on which the leather cushion is laid; after uniformly hardening the gypsum, performing super-flat machining on the region, in which the gypsum is filled, on a numerical control machine tool to guarantee that the super-flat region of the gypsum is flush with the bottom surface of a tool.

Description

The processing method of Thin Walled Curved Noodles part
Technical field
The invention belongs to aircraft Computerized Numerical Control processing technology, relate to a kind of processing method of Thin Walled Curved Noodles part.
Background technology
Now, the processing of a lot of thin wall large curved surface part all can cause the crudy of part poor because the part vibration in process, distortion, overproof, even scraps.The vibration of part in process is sometimes unavoidable, and how the vibration in process being reduced to minimum level, is urgent problem.
Summary of the invention
Object of the present invention: the processing method providing a kind of Thin Walled Curved Noodles part, improves the crudy of thin wall large curved surface part.
Technical scheme of the present invention: a kind of processing method of Thin Walled Curved Noodles part, comprising:
The curved surface of the part machined is spread soft leather pad;
Gypsum is filled with in the part the machined one side region of completing leather packing;
Until after gypsum sclerosis is well-balanced, Digit Control Machine Tool carries out super flat processing to the region of filling with gypsum, ensure that the bottom surface one of the super flat region of gypsum and frock is flat.
Advantage of the present invention: the present invention's gypsum filling thin-walled curved surface class part, part is enriched fastening, be not easy to produce deformation man-hour adding, it is overproof that the processing vibration overcoming Thin Walled Curved Noodles part produces, and cause part cannot meet the problem of delivery quality.Not only cost is low, and economical and practical, serves positive facilitation to the processing of this class part.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram that the present invention pours into gypsum face.
Fig. 2 is installation way schematic diagram of the present invention.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The processing method of a kind of Thin Walled Curved Noodles part provided by the invention, comprising:
S101, on the curved surface of the part machined, spread soft leather pad.
S102, complete leather packing the part machined one side region in fill with on gypsum.
S103 until gypsum sclerosis well-balanced after, Digit Control Machine Tool carries out super flat processing to filling with the region of gypsum, and the bottom surface one of the guarantee super flat region of gypsum and frock is flat.
With embodiment 1, the present invention will be further described below.
Embodiment 1
According to lower Fig. 2 mode, clamping is carried out to part blank, after the complete first surface of complete fine finishining, on the machined surface processed, (see figure 1) spreads soft leather packing (conformal), cover in effective coverage (the piece surface exposed area of part as far as possible, except black skin), prevent from producing corrosion after perfusion gypsum.Then gypsum is poured into wherein, after waiting gypsum to harden completely, super flat process (injecting gypsum makes the curved surface after processing no longer unsettled, completely eliminates the overproof generation of the part caused due to vibration) is carried out to the side of paving gypsum.Require super flat after, gypsum face is consistent with black skin.Then by part turn-over left-hand thread on fixture, standby tight with bolt.Thick and fine finishining process are opened to opposite side.Such operation can avoid part completely after processing one side, and the part caused due to hollow trembles the overproof generation caused.Part after processing not only can well ensure final size requirement, and the surface quality of part also can improve a lot.All process Deng part, can very easily part be taken out when cutting off.This completes the process of whole part.

Claims (1)

1. a processing method for Thin Walled Curved Noodles part, is characterized in that, comprising:
