Description

A kind of flexible adjustable boring tool
Technical field
The present invention relates to a kind of flexible adjustable boring tool, belong to cutting-tool engineering field.
Background technology
At Field of Aviation Manufacturing, more and more higher to the specification requirement of aircraft, in order to eliminate the accumulated error forming due to reasons such as location and assembly deflections in aircraft assembling process, mainly adopt method for finishing manufactured, make assembly parts obtain the higher degree of accuracy.And the degree of accuracy of parts intersection point is the key factor that affects the rear overall aircraft profile degree of accuracy of parts docking.For eliminating the composition error of part manufacture and parts assembling, after having assembled, parts need the combination intersection point of large parts to carry out fine finishining.
Fine finishining adopts machining and manual processing conventionally, traditional true boring cutter in the past, length is long, outside diameter is larger, and the cutter head of boring cutter can not carry out repeatedly adjustable in time processing, and Boring head size is relatively fixing, weight is heavier, operator's labour intensity is large, and working (machining) efficiency is low, and the cost of charp tool is higher.
Summary of the invention
For above deficiency, the invention provides a kind of flexible adjustable boring tool, improve the production efficiency of aviation assembling, reduce the cost of charp tool, alleviate operator's production intensity.
Technical scheme of the present invention: a kind of flexible adjustable boring tool, comprise cutter hub, housing screw, front guide pad, blade, right boring unit, rear guide pad and straight pin, described cutter hub adopts duralumin 7050 materials, wherein cutter hub is axle shape and is connected with lathe, the mid portion of cutter hub is made into protrude round platform, front guide pad is arranged on the place ahead of protruding round platform, rear guide pad is arranged on the rear of protruding round platform, right boring unit is arranged on the side that protrudes round platform by screw, blade is triangular in shape and be arranged in the cutter groove on end, right boring unit by housing screw, described right boring unit comprises fixed body, elevating lever, six side's turn body and dials, fixed body is embedded in cutter hub, dial is arranged on the outer surface of fixed body, six side's turn bodies are hollow bolt shape, its outer surface is threaded with fixed body, its inner surface is fixedly connected with elevating lever.
The present invention has following technique effect: tool weight of the present invention is light, maximum working ability reaches 1mm cutting output, the depth of cut of the each processing of Common boring cutter is 0.1mm, when fine finishining amount is 1mm-2mm, need to use much knives tool, process Chengdu needs feed technique testing department to carry out boring cutter measuring outside diameter at every turn, then use, working (machining) efficiency is extremely low, and the range-adjustable of the flexible boring cutter of the present invention is 3mm-5mm, has reduced usage quantity and the tooling cost of cutter; Right boring unit is adjustable, accurate, can meet the processing request of different size precision, adopt numeral dish at quarter, read conveniently; Blade cut makes with product to be processed contact area little, the moment of torsion having produced while having reduced cutting; Wear-resistant guiding piece is arranged under the prerequisite that guarantees guiding, plays good chip removal function, can reduce again the contact area with drill jig cutter, has avoided the generation of additional torque; Blade is triangular form, and when a tool bit abrasion, adjustable clamp nut, changes another cutter head and use, and has reduced the usage quantity of blade, and it is convenient after blade abrasion, to change, and without returning, repair special cutting tool factory, correction work.
The flexible adjustable boring tool of the present invention, because the materials such as 40Cr that change in the past adopt duralumin 7050, has made to alleviate the weight of boring cutter, has alleviated working strength; Changed traditional boring cutter form, both realized the effect of traditional boring cutter, reduced again the number of cutters of processing same aperture size, blade is only reprocessed need to become flexible the direction that trip bolt turns blade, needn't deliver to special cutting tool factory and reprocess, reconditioning work.In addition, this flexibility adjustable boring tool can be realized boring cutter processing diameter dimension numerical value by right boring unit and read the advantages such as convenient.
