Background technique
The boring cutter used on machining center is one kind of aperture knife tool, usually round handle, and boring cutter is suitable for processing essence
Du Genggao, the bigger hole of diameter.High-precision hole need to carry out heavy boring, right boring, need to carry out chamfering after bore hole, go deburring, hair
Thorn, overlap, burr are fallen into hole during avoiding in use process, influence using.Existing scheme is that machining center uses one
After Common boring cutter right boring, then with one chamfering tool is carried out orifice chamfer, efficiency is lower, increases knife using two tool sharpenings
Have cost, extends single products process time, influence productive temp and production capacity.Bore dia as shown in Figure 1 requires positive and negative
0.01mm, since boring blade processing part tactical diameter is aperture, the installation accuracy of smart thorax blade is not often reached requirement.Together
When, when the tolerance of bore diameter is changed, and is such as changed to+0.01 to+0.02, since boring blade is not easy to adjust, need special
Door customization, processing cost are higher.
Summary of the invention
For above-mentioned deficiency present in the prior art, the technical problem to be solved by the present invention is to existing smart thorax boring cutters can not

Place, the chamfering blade cutting edge and the knife handle axis are in the angle a, and the angle a is 45 degree；
The heavy boring blade, chamfering blade are located at described cutter head the same side, and the essence thorax blade is mounted on the rough boring cutter
The opposite other side of piece is in 180 degree angle, and the essence thorax blade is mounted in blade mounting base, and the essence thorax blade passes through right side
The pressing plate of setting is fixed, the essence thorax blade towards being provided with adjusting threaded hole on the inside of the cutter head, the adjustings threaded hole and
The essence thorax blade flushes, and vertical with the face on the inside of the smart thorax blade, is equipped with interior hexagonal spiral shell in the adjusting threaded hole
Nail, the soket head cap screw can push the smart thorax blade when screwing in.
Further, the heavy boring blade, chamfering blade are mounted on the cutter head by the nut of M3X7.
Further, the heavy boring blade processing diameter is 0.2mm smaller than the smart thorax blade processing diameter.
Further, the heavy boring blade, chamfering blade use TPMT110304 triangle inner hole blade.
Further, the pressing plate model CPS-5V.
Further, the smart thorax blade uses tetra- jiaos of blades of CCMT060204.
Further, the adjusting threaded hole specification is M5.
Further, the adjusting threaded hole center passes through the Jing Tang blade center.
Further, the smart thorax blade is the depth for not doing desired bore portion at a distance from the cutter head end face.
Working principle of the present invention:
This essence thorax cutter is integrated with heavy boring blade, chamfering blade, smart thorax blade simultaneously, smart thorax is carried out after heavy boring, due to peace
Dress and processing problems, are extremely difficult to the precision of positive and negative 0.01mm and pass through cutter tune after smart thorax blade is mounted in blade mounting base
Whole instrument measures processing diameter, then screws in soket head cap screw by adjusting threaded hole, to pass through percentage sideways against smart thorax blade
Table controls actuating length, thus by the adjustment of smart thorax diameter in standard of tolerance.If adjusting instrument without stage property, measured after boring can also be tried
Bore hole actual diameter, then be adjusted.When bore hole tolerance variation or boring another kind equivalent diameter, when the discrepant hole of tolerance,
The use of boring cutter can be extended by fine tuning.
General essence bore only has orifice position precision prescribed higher, therefore smart thorax blade setting is located proximate to cutter head tail
Portion is only machined near the aperture of required precision.
Chamfering blade can be processed at one time with heavy boring, smart thorax process, and efficiency is higher.
The beneficial effects of the present invention are:
