Description
Technical field
The utility model relates to a kind of indexable brill boring chamfering compound tool, belongs to the compound tool technical field.
Background technology
Be the hole of steel part processing 8 class precisions about 30HRC in hardness, adopt the processing of boring and bore hole two procedures usually, need locate carry out chamfering in the aperture at last.
At present to the middle worker 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 the drilling machine and reaming after, carry out bore hole and chamfer machining with boring cutter again.Though this cutter is cheap, high-speed steel drill is not wear-resisting, and service life is short, and cutter consumption is big, needs often to change cutter, so the processing cost height, 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, carries out bore hole with the right boring blade at the machining center of high rigidity or building-block machine again.Though the shallow hole drilling cutter is easy to use, and working (machining) efficiency is higher, but boring and bore hole need be divided into two procedures, and processing respectively, increased the debug time of cutter on the one hand, and twice processing also exists the problem that can't guarantee stable processing quality, and can not further improve working (machining) efficiency.
Summary of the invention
The utility model purpose provides a kind of rational in infrastructure, compact, and stable processing quality can further improve the indexable brill boring chamfering compound tool of working (machining) efficiency.
The utility model is that the technical scheme that achieves the above object is: a kind of indexable brill boring chamfering compound 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, the inner edge blade is installed in inner edge chip area front portion, the outside blade is installed in outside chip area front portion, 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 installed on the 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 the 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 utility model 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, can make the iron filings of the inner edge cutting of the shallow hole drilling minor diameter that curls little and to have a distortion big, make the iron filings rigidity relatively weaker, it is smaller to the influence of iron filings boring cutter sheet to reduce iron filings, inner edge chip area space is greater than the outside chip area in addition, can effectively avoid be subjected to the holing influence of iron filings of right boring blade, guarantee accurately machined precision.Cutter holder of the present utility model is installed on the knife bar, and can axial adjustment, and the right boring blade radially can be regulated and is installed on the cutter holder, therefore makes things convenient for the keyhole degree of depth and bore hole aperture.It is logical with the hole drill on the steel part that the utility model adds the inner edge blade and the outside blade that utilize man-hour on the shallow hole drilling, recycling right boring blade carries out bore hole, at last by the chamfering blade on the knife bar to the aperture chamfering, can once finish boring, bore hole and chamfering, multiple working procedure can be combined, reduce aided process, can further improve the working (machining) efficiency height, and can finish the processing in steel part 8 class precision holes by efficient high texture.
