Problems solved by technology

[0003] ①Inner main flaps and slide rails are important stress-bearing and moving parts of the aircraft, and they are always subject to alternating loads during the whole process of aircraft taxiing, take-off, flight, landing and landing. This alternating load requires the inner main flaps The connection surface with the slide rail has high fatigue resistance, and the method of adding pads does not meet the fatigue resistance requirements, and ca

Abstract

The present invention provides a portable three-coordinate milling machine and a machining method thereof, both of which are used for precision machining on high-accuracy mounting surfaces of some important parts on an aircraft assembly production line to meet the accuracy requirements of the mounting surfaces. The portable three-coordinate milling machine and the machining method thereof involve a flat plate assembly, an upright assembly, a sliding table assembly, a milling head and an integrated control system. When the portable three-coordinate milling machine is used for machining aircraft parts, machining can be implemented according to such steps as pre-tensioning, tool setting, cutting amount calculation and milling machining. The pneumatic milling head is compact in structure and thus can be mounted on a portable machine tool and an industrial robot in an adaptive manner. Compared with a motor milling head, the pneumatic milling head has higher cost performance.

Description

technical field [0001] The application relates to the field of machining and manufacturing equipment for aircraft parts, in particular to a portable three-coordinate milling machine. Background technique [0002] The Boring737MAX-IF inner flap part is composed of two main parts, the inner main flap and the inner rear flap, with a length of 3.6 meters and a width of 1.5 meters. The number of parts and components of a single product is 718. The assembly features of this product have the characteristics of high requirements for interchangeability, strict control of appearance requirements, narrow construction space, and relatively complicated internal structure. In the area of ​​281mmx307mm in the middle of the lower wing surface of the inner main flap, there are four installation surfaces that need to be finished. On the installation surface, the slide rail frame should be accurately installed. The sizes of these four installation surfaces are: 44mmx85mm, 45mmx87mm, 100mmx43mm...
