Universal numerical control milling tool for small-sized structural parts of aircraft

Abstract

A universal numerical control milling tool for small-sized structural parts of an aircraft comprises a fixed base, rotary supporting rods and a machining base, wherein the two rotary supporting rods are symmetrically and fixedly mounted on the two sides of a plurality of machining clamp plate mounting holes; the two rotary supporting rods are embedded in the two sides of the top of the fixed base separately; positioning bolts are embedded in the fixed base and the rotary supporting rods from the top of the fixed base and fix the rotary supporting rods; the machining clamp plate mounting holes are formed in the outer side of the machining base; machining pressing plates are mounted on the tops of the machining clamp plate mounting holes through bolts. The machining base is beneficial for use convenience, is a rotatable device and is of a cuboid-shaped structure, before machining, raw materials to be machined are first fixed on different machining surfaces of the machining base through the machining pressing plates, after the structural part on one surface is machined, the other surfaces can be utilized to machine different structural parts by rotating the machining base, the rotating process is simple, and time is effectively saved.

Description

technical field [0001] The invention relates to the technical field of mechanical tooling fixtures, in particular to a universal digital milling tooling for small aircraft structural parts. Background technique [0002] In the past, the main parts of the aircraft body were assembled from sheet metal parts. Later, with the continuous improvement of aircraft performance, the overall structure increased day by day. Due to the emergence of integral frames, beams, and ribs and the wide application of integral wall panels, the types and varieties of machined parts are increasing. In the production of certain types of aircraft, the proportion of labor in machined parts has exceeded that of sheet metal forming. Parts, and the aircraft factory equipment and plant layout have also changed accordingly. For example, the overall structural parts of some airliners account for 65% of the weight of the fuselage, so the overall structural parts play an increasingly important role in the aer...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of universal digital milling tool for small structural parts of aircraft, to solve the problem that the existing digital milling tool for small structural parts of aircraft proposed in the above background technology needs frequent replacement of tooling because there are many kinds of structural parts during processing, but The replacement process is complicated and wastes a lot of time. Although some fixtures are installed with different kinds of fixtures, it is still impossible to better avoid the problem of wasting time caused by replacement in the face of a large number of structural parts.
