Developed treatment of a kind of boring to be opposite quickly knife device. With try the photograph that cut a way to compare, use this device but apparently managing bore hole pair of knife time when treatment, rise bore hole the productivity of treatment. In treatment of 1 foreword boring " try cut a way " machine in the spare parts namely be cut through trying ceaselessly in the process and undertake metrical to already machining dimension, cutting tool photograph is adjusted to machine exterior position to workpiece accordingly after be being measured every time, till achieve the treatment method of requirement of precision of spare parts dimension. Because try every time,cutting tool is adjusted after cutting (to the knife) should spend time, when processing the work with dimension more expensive precision especially, try cut, detect, this one process needs tone knife to undertake for many times repeatedly, the impact of opposite yield should consider when because this is used,trying the treatment that cut a way. Bore hole to batch treatment, should use try cut a law to win pair of knife measure, use next already the completes a batch of work to knife dimension treatment of mix up, when the dimension precision that scores this working procedure hole, because use,try the time that cuts a law to be cost to knife place to partake by every workpiece in batch, accordingly, use try cut a way very small to the influence of boring productivity. But to sheet for the boring treatment of aperture of small lot spare parts, use the influence that tries the time that cuts a law to be spent to knife place to machine productivity to aperture quite remarkable. In addition, the effect that the competence of handlers leads to machining effect is very apparent also. Develop treatment of a kind of boring to be opposite quickly knife device, can shorten significantly already cutting tool settling time, do not have special requirement to the skill level of handlers again, this is the problem that article place should solve. The 2 cutting tool when be being machined to the design boring of knife device quickly are right knife signal. Knowable, the treatment dimension that bore hole (be opposite namely knife dimension) it is 2 times what boring cutter needle nods A to go to boring lever center to be apart from, namely Ød1=2(Ød/2+ab) (1) criterion because Ab=(Ød1- Ød)/2(2) is foregone type (the Ød of boring shank diameter in 1) , because this wants to decide A of boring cutter point of a knife arrives outside boring lever only,round face is in the distance Ab on radius Oa, can decide pair of knife dimension Ød1 that bore hole. But the distance because of Ab uses measure directly hard or quantity appearance is measured, reason cannot direct basis type (1) decides pair of knife dimension Ød1. The boring treatment that the article designs can solve this one difficult problem to knife device quickly. Boring treatment is opposite quickly the design of knife device, this device by magnetic force V bolt of locking of staff guage of bracket of mat of form piece, insulation, staff guage, activity, staff guage, direct current source, right the composition such as knife indicator light. Form piece secures the magnetic force V in using device of magnetic force general to go up in boring lever, use magnetic force V the in be opposite action of form piece, make of boring lever outside round center is right in in V form piece on the symmetrical face of two cant, with assemble make sure mobile staff guage is located in form of magnetic force V piece on the symmetrical face of two cant, in order to no matter,assure form of magnetic force V piece the where at the circle outside boring lever, the central axle that can ensure face of mobile staff guage passes the circle outside boring lever is sectional, the radius that the osculatory dot that assures underside of mobile staff guage and apogee of point of a knife namely is located in A of point of a knife and O of boring lever center connects a line to go up, the current scale value that uses the designation on mobile staff guage thereby measures the space that gives Ab, again according to type (1) bores hole certainly pair of knife dimension Ød1 of the diameter; Lever of specific to some boring is returned can be directly according to the diametical dimension of boring lever on mobile staff guage the diametical scale value that line out place measures apogee of point of a knife, can give out directly so bore hole pair of knife dimension Ød1 of the diameter. Accordingly, this boring treatment has special sex already to knife device quickly, have versatility again. Survryor's rod of activity of locking of bolt of rear sight locking is used in device, prevent mobile staff guage to be in shift produces after determining pair of knife size; Form of magnetic force V piece with rear sight fill up with insulation between bracket undertake is isolated from; When mobile staff guage and boring cutter point of a knife are contacted, bright to knife indicator light, express to adjust reach pair of knife size (it is) of pair of power supply of knife indicator light with direct current source. 3 be opposite quickly the use of knife device to afore-mentioned already but special but current boring treatment is opposite quickly knife device, its are used from time to tome two kinds adjust a circumstance. The scale value when line out of place of mobile staff guage is according to some place of direct line out measures the diameter of specific boring lever when the diametical scale of apogee of point of a knife is worth, boring cutter is suddenly to the tone synchronization of knife dimension: Presetting is right the mobile staff guage of knife device, make its scale is equal to the diametical dimension that is bored hole, use survryor's rod of activity of locking of bolt of rear sight locking next; With magnetic force V device secures pair of knives with form good preliminary adjustments piece in boring lever outside round apparently, adjust boring cutter point of a knife carefully to make its and underside of mobile staff guage are contacted, when boring cutter point of a knife adjusts the diametical dimension that is bored hole, to the knife indicator light will shine slightly, use boring tool of locking of bolt of boring cutter locking right now, the process ends pair of knives that bore hole. To the boring lever of different diameter dimension, boring cutter goes to entering above all when the knife preliminary adjustments: magnetic force V form piece is secured in boring lever outside round apparently, be down mobile activity staff guage carefully, when round face is contacted outside rear sight underside and boring lever, to the knife indicator light will shine slightly, note the current scale cost of next mobile staff guage right now; It is start with this scale, activating staff guage moves up by type (the Ab distance that 2) computation gets, next locking activity staff guage, preliminary adjustments process ends. Repeat after preliminary adjustments (1) is planted the adjustment of the circumstance process, till achieve pair of knife requirements. The error of device of 4 pairs of knives is analysed (the generation of 1) error uses this device to the ideal of the knife the position is bottom of mobile staff guage form piece of C dot and magnetic force V the symmetrical axis of two cant is sectional on B nods coincide, but the existence as a result of all sorts of errors, positional B nods ideal of deviate of dot of C of bottom of activating staff guage and produce pair of knife errors, among them because mobile staff guage and aperture of rear sight bracket use clearance fit,the mainest reason is, make C nods positional happening to change, affect pair of knife errors that cause thereby to knife dimension. (The computation of 2) error sets ideal diameter to be Ød1 to knife dimension, r=Ød1/2, error of pairs of the biggest knives is Δ Max, criterion Cd is be opposite actually the 1/2 of knife dimension, ob=r=Ød1/2, the biggest gap of mobile staff guage and aperture of rear sight bracket is δ Max, √ of knowable Δ Max=2(ob-cd)=2(r- ) 2max of R2- δ criterion 2max of δ of Max+4 R2=4r2- 4 of 2max- 4r Δ of Δ of 2max of δ of R2- of Δ Max-2r=-2 √ because Δ 2max value is very little can ignor, type of 2maxr(3) basis of δ of ≈ of reason Δ Max (3) , like the graph to Max of knife error Δ and the relation to knife dimension 5 are shown, can see Max of pair of knife error Δ be reduced as the addition to knife dimension R. Computational example: Be like pair of knife dimension R=10mm, the Max=0 of δ of the biggest gap of mobile staff guage and aperture of rear sight bracket. 01mm, according to type (3) , have Δ Max=(0.
01)2/10=0.
00001 (mm) passes afore-mentioned computation knowable, max of pair of knife error Δ that use clearance fit place to cause by mobile staff guage and aperture of rear sight bracket and mobile staff guage and hole of rear sight bracket are the largest photograph of clearance δ Max is smaller than wanting much, enough satisfies the precision requirement of pair of knife dimension. 5 epilogue are in bore hole in machining a process, use boring treatment to be opposite quickly knife device, can decrease significantly adjust bore hole the time of pair of knife dimension. When the many opening that attend in boring coaxial especially, use pair of knife measure that adjust each aperture quickly to knife device originally, can make poriferous treatment of a boring, rise greatly bore hole treatment productivity.
