Embodiment Construction

[0031] A method for processing special-shaped thin-walled shell parts, including several steps of plate preparation, rough milling, alignment, aging treatment, finishing cavity end face, finishing milling bottom surface and shape, finishing cavity and removing blank, the specific steps are as follows :

[0032] S1. Spare board: Select a square board 1 with regular shape, thickness and appropriate size according to the parts selection. The material thickness of the square board 1 is at least 5mm greater than the thickness of the part, and the length and width of each side are at least 40mm greater than the length and width of the part; that is, first supplement the special shape It is square; it is convenient for clamping, alignment, and strength in subsequent processing, saving special tooling.

[0033] S2. Rough milling: Roughly mill the ring groove 21 of the contour shape of the part on the square plate 1 to release the stress and prevent the deformation of the part after fi...

Abstract

The invention discloses a machining method for a specially-shaped thin-wall shell body part. The machining method for the specially-shaped thin-wall shell body part comprises the steps of plate preparation, rough milling, alignment, aging treatment, finish machining for an end surface of a cavity, finish milling for a bottom surface and a shape, finish milling for the cavity, and blank removal. According to the machining method for the specially-shaped thin-wall shell body part, accurate location is carried out in a machining process through a location pin hole, the part is installed on a fixed clamp in a clamping manner to be fixed, and the effects of supporting and preventing vibration are acted by reserving a process cylinder in the cavity, so that complete machining for the specially-shaped thin-wall shell body part can be realized; and the machining method for the specially-shaped thin-wall shell body part has the advantages of facilitating to clamping, and being capable of preventing the part from being deformed, saving production for a special fixture, and increasing the machining efficiency, the machining accuracy, the production efficiency and the product qualification ratio.

Description

technical field [0001] The invention relates to the technical field of parts cutting and processing, and more particularly relates to a method for processing special-shaped thin-walled shell parts. Background technique [0002] At present, thin-walled shell parts are widely used in the field of aerospace parts processing. They have the characteristics of irregular shape, thin structure, and large margin for removing blanks. In the prior art, special-shaped thin-walled shell parts are The conventional clamping method cannot fix the part and it is not easy to align. During the cutting process, vibration and deformation are easily generated. After processing, the part finish is poor and the size is seriously out of tolerance. [0003] Usually, some special tooling will be made, but in actual production and processing, the processing cycle is long and the production efficiency is low. Contents of the invention [0004] The technical problem to be solved in the present inventi...
