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

Abstract

A general digital milling tool for small structural parts of aircraft, comprising a fixed base, a rotating support rod and a processing seat; two rotating support rods are symmetrically fixed and fixed on both sides of the mounting hole of the processing splint; the two rotating support rods are embedded respectively to both sides of the top of the fixed base; the positioning bolts are inserted into the fixed base and the rotating support bar from the top of the fixed base and fix the rotating support bar; the outside of the processing seat is provided with a number of mounting holes for processing splints; the processing press plate passes through The bolts are mounted on top of the mounting holes of the machining clamps. The setting of the processing seat in the present invention is conducive to the convenience of use. The processing seat is a rotatable device, and the processing seat is a cuboid structure. Before processing, the raw materials to be processed are respectively fixed on different processing surfaces of the processing seat through the processing platen. , when the structural parts on one surface are processed, the rotary processing seat can use the other surface to process different structural parts. The rotation process is relatively simple and effectively saves time.

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...

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.
