Abstract

The invention discloses a deformation control method for numerical control machining of an overall aircraft emergency gate. The deformation control method comprises the following steps that the machining deformation direction and deformation quantity of a to-be-machined part are analyzed, and a preliminary pre-judged result of machining deformation is obtained; the reversible deformation quantityrequired by the to-be-machined part is estimated according to the preliminary pre-judged result, and required preload is obtained; a preload clamping tool is designed and manufactured according to thecalculation result; preload clamping of the to-be-machined part is conducted through the preload clamping tool; and the to-be-machined part is machined in a preload clamping state. According to the deformation control method for numerical control machining of the overall aircraft emergency gate, the great deformation control effect is good, and the deformation control method further has the advantages of low implementation cost, easy realization and high feasibility and is suitable for large-scale industrial production and popularization.

Description

technical field [0001] The present invention relates to the technical field of numerical control processing of aviation integral structural parts, and the process method involved, in particular to a method for controlling the numerical control machining deformation of an integral emergency door of an aircraft by using preload clamping, specifically to a numerical control process for an integral emergency door of an aircraft Machining deformation control method. Background technique [0002] For aircraft, especially large passenger aircraft, emergency door is an important device necessary for escape in an emergency. Due to the complex structure of the parts related to emergency doors, there are high requirements for manufacturing. The domestic and foreign aviation manufacturing fields generally adopt the form of assembly parts for assembly and manufacturing. [0003] In order to further improve the overall structural performance of large aircraft, reduce the assembly workloa...
