Abstract

The invention provides a boring-based cantilever shaft machining method for achieving large-size irregular appearances. Through cooperative use of a blade, a blade reinforcing plate, a diameter fine adjustment nut, a dial, a cutter body mounting mechanism, a machining arm, a cooling liquid channel, a balance arm, a rigid reinforcing ring, an avoiding hole and a cutter handle cone, a large-length-diameter-ratio cantilever shaft is precisely machined in a common machining center, the blade is cooled, the cutter rigidity is improved, workpiece vibration is restrained, the machining precision of parts of the type is improved, the cost is saved, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the field of machining, in particular to a cantilever shaft machining method based on boring to realize large-sized irregular shapes. Background technique [0002] Since the cantilever shaft in the aircraft rudder wing parts has the characteristics of precise size (diameter accuracy better than IT6, cylindricity better than 0.01mm), large aspect ratio (greater than 6), and large size irregular rudder surface (multi-angle plane Or curved surface, the external dimension is not less than 800mm)) as an integral structure. Traditional processing uses precision lathes or grinding to ensure the dimensional accuracy and cylindricity of the rudder shaft. Considering the large size of the rudder surface (greater than 800mm), large-scale turning or grinding equipment is required; the irregular structure of the rudder surface makes it difficult to clamp; the rudder shaft protrudes long and has poor rigidity; the special Scarcity of expen...
