Description

Indexable brill boring chamfer compound cutting tool
Technical field
The present invention relates to a kind of indexable brill boring chamfer compound cutting tool, belong to the compound tool technical field.
Background technology
The hole of processing 8 class precisions on steel part about hardness is 30HRC adopts boring and bore hole two procedures to process usually, need to carry out chamfering at the place, aperture at last.
At present to the middle work in the hole of 8 class precisions, a kind of be by hole on the common high-speed steel drill work in-process heart or drilling machine and reaming after, then carry 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, need often to change cutter, so processing cost is high, and working (machining) efficiency is very low.Another kind is to adopt the shallow hole drilling compound tool, and the knife bar end is separately installed with inner edge blade and outside blade, by shallow hole drilling compound tool subdrilling through hole on steel part, then carries out bore hole with the right boring blade on the machining center of high rigidity or building-block machine.Although the shallow hole drilling cutter is easy to use, and working (machining) efficiency is higher, but boring and bore hole need to be divided into two procedures, and processing respectively, increased on the one hand the debug time of cutter, and twice processing also exists the problem that can't guarantee crudy stability, and can not further improve working (machining) efficiency.
Summary of the invention
The object of the invention is to provide a kind of rational in infrastructure, compact, and crudy is stable, can further improve the indexable brill boring chamfer compound cutting tool of working (machining) efficiency.
the present invention is that the technical scheme that achieves the above object is: 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 that is connected with tool rest, the front portion is provided with inner edge chip area and outside chip area, it is anterior that the inner edge blade is arranged on the inner edge chip area, it is anterior that the outside blade is arranged on the 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 equipped with adjustable cutter holder vertically, the right boring blade radially can be regulated and 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 equipped 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 the 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 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 iron filings of inner edge cutting that can make shallow hole drilling is little and to have a distortion large, make the iron filings rigidity weaker, reduce iron filings smaller on the impact of iron filings boring blade, inner edge chip area space is greater than the outside chip area in addition, can effectively avoid be subject to the holing impact of iron filings of right boring blade, guarantee accurately machined precision.Cutter holder of the present invention is arranged on knife bar, and can axial adjustment, and the right boring blade radially can be regulated and is arranged on cutter holder, therefore facilitates the keyhole degree of depth and bore hole aperture.The present invention adds the inner edge blade and the outside blade that utilize man-hour on shallow hole drilling, and the hole drill on steel part is logical, recycling right boring blade carries out bore hole, at last 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, can further improve working (machining) efficiency high, and can efficient high texture complete the processing in steel part 8 class precision holes.
