Apparatus, system and method for processing aerospace joints

Abstract

The invention provides a machining device, system and method of an aviation joint. The joint comprises fork lugs and a rotating structure. The machining device comprises a base, two outer supporting parts, an inner supporting part and a positioning part, wherein the two outer supporting parts, the inner supporting part and the positioning part are arranged on the base; the two outer supporting parts are arranged on the two sides of the positioning part; the inner supporting part is arranged between the two outer supporting parts and can do rotational movement along a middle axis face of the positioning part; the positioning part is used for positioning the rotating structure; the inner supporting part is used for performing rigid supporting on the interiors of the fork lugs; and the outersupporting parts are used for performing rigid supporting on the exteriors of the fork lugs. The machining device, system and method of the aviation joint can play a damage preventing role in helicopters placed in an external field, and guarantee the safety of parking in the airplane external field.

Description

technical field [0001] The invention relates to the technical field of aviation numerical control machining, in particular to an anti-deformation control device and a processing method for a joint fork lug with a rotary structure of an aviation belt. Background technique [0002] The structural components of the mechanical aviation system include many fork lug joint parts with rotary structures. The wall thickness of the fork lug part of these parts is thin, and affected by the assembly relationship, the dimensional accuracy requirements are high, but the rigidity of the overall processing system is poor. Easy to deform. [0003] According to the traditional processing method, manual scribing, ordinary milling machine milling are used, and the assembly and combination fixture is used for clamping and processing. The influence of deformation in the processing process is difficult to control. Repeated shape correction after processing often occurs. Product size and The accura...

Deformable

[0003] According to the traditional processing method, manual scribing, ordinary milling machine milling are used, and the assembly and combination fixture is used for clamping and processing. The influence of deformation in the processing process is difficult to control. Repeated shape correction after processing often occurs. Product size and Poor precision control consistency, low product qualification rate, and low processing efficiency, unable to meet normal production and assembly requirements
