Description
Technical field
The present invention relates to a kind of indexable brill boring chamfer compound cutting tool, belong to compound tool technical field.
Background technology
In hardness be about 30HRC steel part on process the hole of 8 class precisions, usually adopt boring and bore hole two procedures to process, finally need to carry out chamfering at aperture place.
At present to work in the hole of 8 class precisions, one is by after the common high-speed steel drill work in-process heart or drilling machine carry out boring and reaming, then carries out bore hole and chamfer machining with boring cutter.Although this cutter is cheap, high-speed steel drill is not wear-resisting, and service life is short, and cutter consumption is large, and need often to change cutter, therefore processing cost is high, and working (machining) efficiency is very low.Another kind adopts shallow hole drilling compound tool, and knife bar end is separately installed with inner edge blade and outside blade, by shallow hole drilling compound tool first holes drilled through on steel part on the machining center or building-block machine of high rigidity, then carries out bore hole with right boring blade.Although shallow hole drilling cutter is easy to use, and working (machining) efficiency is higher, but need boring and bore hole to be divided into two procedures, and process respectively, add the debug time of cutter on the one hand, and twice processing also also exists the problem that cannot ensure crudy stability, and working (machining) efficiency can not be improved further.
Summary of the invention
The object of the invention is to provide a kind of rational in infrastructure, compact, and crudy is stablized, and can improve the indexable brill boring chamfer compound cutting tool of working (machining) efficiency further.
The present invention is the technical scheme achieved the above object: a kind of indexable brill boring chamfer compound cutting tool, comprise knife bar, inner edge blade and outside blade, knife bar is positioned at shaft shoulder rear portion and is provided with the handle of a knife be connected with tool rest, front portion is provided with inner edge chip area and outside chip area, it is anterior that inner edge blade is arranged on inner edge chip area, it is anterior that outside blade is arranged on outside chip area, it is characterized in that: the middle and upper part that described knife bar is positioned at inner edge chip area place is provided with adjustable cutter holder vertically, right boring blade is radial adjustable to be arranged on cutter holder, and the end face of right boring blade is lower than the groove bottom of inner edge chip area, the shaft shoulder front end face of knife bar is provided with chamfering blade, cooling water channel in knife bar respectively with right boring blade water channel, outside blade water channel and inner edge blade water channel communicate, and right boring blade water channel, the front end of outside blade water channel and inner edge blade water channel is separately positioned on right boring blade, outside blade and inner edge blade place.
The present invention is on the basis of former shallow hole drilling cutter, be positioned at inner edge chip area place at knife bar and cutter holder and right boring blade are installed, especially the end face of right boring blade is lower than the groove bottom of inner edge chip area, the curling minor diameter of the iron filings that the inner edge of shallow hole drilling can be made to cut is little and have distortion greatly, make iron filings rigidity weaker, reduce iron filings smaller on the impact of iron filings boring blade, in addition inner edge chip discharge groove is greater than outside chip area, right boring blade effectively can be avoided to be subject to the impact of boring iron filings, to guarantee accurately machined precision.Cutter holder of the present invention is arranged on knife bar, and can axial adjustment, and right boring blade is radial adjustable is arranged on cutter holder, therefore facilitates the keyhole degree of depth and bore hole aperture.The present invention adds inner edge blade on utilization of hour shallow hole drilling and the hole drill on steel part leads to by outside blade, recycling right boring blade carries out bore hole, finally by the chamfering blade on knife bar to orifice chamfer, can once complete boring, bore hole and chamfering, multiple working procedure can be combined, reduce aided process, working (machining) efficiency can be improved further high, and efficiently can complete the processing in steel part 8 class precision hole by high texture.
