The utility model content

The utility model technical problem to be solved provides a kind of macropore boring cutter, can be used for the bigger hole of machining center boring diameter, and working (machining) efficiency is high, and the diameter of its bore hole is adjustable, and the bore hole precision is high.

For solving the problems of the technologies described above; The utility model provides a kind of macropore boring cutter; It is characterized in that, comprise a knife rest, be arranged at said knife rest one side a plurality of holders, with the boring head that said holder removably is connected, the end of said boring head is provided with the boring cutter of adjustable positions.

Said holder comprises base and free end, and the installing hole that is connected with said knife rest is set on the said base; Said free end is an open circles ring body, and said torus sidewall is provided with a through hole.

Said free end end face is provided with locating convex block.

Said boring head comprises the groove that can hold said locating convex block on the face of said holder.

Said boring head comprises the cylinder that can stretch in the said free end open circles ring body on the face of said holder, said cylinder be provided with said torus on the through hole that matches of through hole.

The end of said boring head is provided with a groove, is provided with two internal thread holes in the said groove.

Said boring cutter is provided with slotted hole, boring cutter is fixed in the groove of said boring head end through said slotted hole and said internal thread hole by securing member.

The mohs bush handle of a knife is connected in said knife rest opposite side and the machining center.

The beneficial effect that the utility model reached:

The macropore boring cutter of the utility model can be connected with mohs bush handle of a knife in the machining center, is used for the bigger hole of boring diameter, and working (machining) efficiency is high; According to bore diameter; Two boring heads adjustings on the macropore boring cutter are mounted on the holder of correct position; Thereby the diameter of scalable institute bore hole, and the boring cutter on each boring head can finely tune through regulating the installation site of boring cutter in slotted hole, makes the bore hole precision higher.

Among the figure, knife rest 1, holder 2, base 21, free end 22, fixing hole 23, through hole 24, end face 25, locating convex block 26, boring head 3, link 31, working end 32, end face 33, groove 34, boring cutter 4, slotted hole 41, bolt 5, bolt 6, securing member 7, mohs bush handle of a knife 8.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.

Like Fig. 1, Fig. 2 and shown in Figure 3, the macropore boring cutter of the utility model comprises a knife rest 1, is arranged at a row, a plurality of holder 2 of knife rest 1 one sides, on the holder 2 boring head 3 can be installed, and the end of boring head 3 is provided with the fine-tuning boring cutter in position 4.

Holder 2 comprises base 21 and free end 22, and fixing hole 23 is set on the base 21, and is corresponding with the fixing hole that is provided with on the knife rest 1, can holder 2 be connected with knife rest 1 through bolt 5 securing members such as grade.Free end 22 is an open circles ring body, and the torus sidewall is provided with a through hole 24, is used for fixing boring head 3, and free end 22 end faces 25 are provided with two locating convex blocks 26.

Boring head 3 comprises a link 31 and a working end 32; Free end 22 on link 31 and the holder 2 is connected; Be link 31 with 25 contacted of free end 22 end faces on comprise two grooves that can hold locating convex block; Also comprise one on link 31 end faces and can stretch into the interior cylinder of free end open circles ring body; Cylinder be provided with torus on the through hole that matches of through hole, can a bolt 6 be passed the torus of free end and the through hole on the link cylinder, boring head 3 is installed on the holder 2.Boring head 3 working ends 32 end faces 33 are provided with a

groove

34, and 34 are provided with two internal thread holes in the groove.

Boring cutter 4 is provided with at least two slotted holes; Boring head is provided with three slotted holes 41 in the present embodiment; Two slotted holes 41 that use securing members 7 such as screw, bolt to pass wherein are fixed in boring cutter 4 in the groove 34 of boring head 3 working ends 32 end faces 33, and boring cutter 4 is embedded in the groove 34 of working end end face 33 just.Through the fixed position of securing members such as adjustment screw, bolt 7 in slotted hole 41, can regulate boring cutter 4 and be fixed in the position on the boring head 3, realize fine setting to boring cutter 4 fixed positions.
