Example Embodiment

[0056] Example 1

[0057] Please refer to image 3 with Figure 4 The clamping device includes a base 1, a first compression mechanism 2, a second compression mechanism 3, and a support fastening mechanism 4, and the first compression mechanism 2 and the second compression mechanism 3 are respectively disposed at both ends of the base 1, respectively. The support fastening mechanism 4 is disposed between the first compression mechanism 2 and the second compression mechanism 3, and an axial positioning mechanism 5 is provided between the first compression mechanism 2 and the second compression mechanism 3. The blanks include a square process table, mounting plate, blade, round counter, and a circular work desk. The first compression mechanism 2 is used to assemble a round counter or a circular process table that supports the fastening mechanism 4 for the blade of the clip, and the second compression mechanism 3 is used to load the mounting plate of the clip. And square craft table, a...

Abstract

The invention discloses a machining process of an aero-engine blade, and particularly relates to the technical field of aero-engine blade precision machining. The machining process of the aero-engine blade comprises a blank material, and the blank material comprises a square process table, a mounting plate, the blade, a circular table and a circular process table which are sequentially arranged; the machining process comprises the following steps that S1, the blade is clamped, and rough machining is conducted on the square/circular process table; S2, the square/circular process table is clamped, and the mounting plate, the blade and the circular table are roughly milled; S3, the blank material is subjected to destressing treatment; S4, re-clamping is carried out, and finish machining is carried out on the mounting plate, the blade and the circular table; S5, the mounting plate and the blade are clamped, and the circular table is repaired; and S6, the circular table and the mounting plate are clamped, the circular process table is machined to form an assembly shaft, the square process table is milled off, and machining is completed. The machining process can effectively solve the problems that when the aero-engine blade is machined, large deformation occurs, and the machining quality and precision of the blade are reduced.

Description

technical field [0001] The invention relates to the technical field of precision machining of aeroengine blades, in particular to a processing technology of aeroengine blades. Background technique [0002] The aviation industry is compared to the crown of modern industry, and the aero-engine is even called the jewel in the crown of modern industry, which is the heart of the aircraft. During the use of aero-engines, blades are the key components of aero-generators, and the processing quality of aero-engine blades determines the performance level and service life of aero-engines. [0003] Aeroengine blades include turbine blades, compressor blades and fan blades. Fan blades are generally made of titanium alloy or aluminum alloy. The traditional processing route of this type of blade is to process the blade after both ends of the blade are processed. When cutting the blade, it is easy to damage the blade structure, and it will also affect the structure of both ends of the proc...
