Description
Technical field
The present invention relates to a kind of cutter, more particularly to a kind of drilling tool.
Background technology
Mainly cutting end part bears cutting force when drilling tool is cut, and chip can only be arranged from cutting end part through chip pocket
Going out, cutting end part produces amount of deflection compared with the shank of clamping during cutting end part stress, while in order to which chip can be quickly from chip pocket
Discharge, chip pocket generally have core thick ratio the diameter of drilling tool between of the larger chip space so as to drilling tool
Smaller, the side face that the amount of deflection of change easily makes cutting end part follow intensity low vibrates, and cutting end part to shank, which overhangs, gets over jumping chisel
The rigidity of spot facing cutter is poorer, thus overhang long drilling tool processing when be more prone to occur vibration and more acutely, during cutting
Generation vibration cause drilling tool fracture, machined surface quality is poor, dimensional accuracy is low, while vibrational energy make cutting tip wear compared with
It hurry up, reduce the service life of cutting tip, in order to ensure the service life of blade, avoid drilling tool fracture from causing workpiece to scrap, bore
Spot facing cutter is generally only used for the use occasion that processing aperture ratio is little, machined surface quality is not high.
The problems such as bore edges flange, burr occurs in existing drilling tool with being difficult to avoid that.
The content of the invention
The present invention is in order to solve drawbacks described above and deficiency existing in the prior art, there is provided a kind of drilling tool.
In order to solve the above technical problems, the present invention provides a kind of drilling tool, including cutter hub and handle of a knife；
The cutter hub includes cutter head, blade and trimming knife, and the cutter head includes being arranged on operator and the auxiliary of blade end
Knife, the blade are made of helical form dregs guiding groove one and side face, and the auxiliary knife is fixed on the end of the side face, the modification
One end of knife is fixed on the other end of the blade, and the trimming knife includes umbrella-type modification knife face and is integrally formed with modification knife face
Modification blade, the other end of the trimming knife is fixed on connector one, and the handle of a knife end is equipped with connector two, the company
Fitting one is the cylinder with circular groove, the cylinder that the connector two matches for size with the circular groove, institute
Cutter hub is stated to be fixed together by the inserting mode of connector one and connector two.
Further, the handle of a knife includes integrally formed main handle and block, the cross-sectional area of the block and the connection
The cross-sectional area of part one is equal.
Further, integrally formed adapter, the cross section of the adapter are equipped between the main handle and the block
Cross-sectional area, cross-sectional area more than the main handle of the product less than the connector.
Further, the surface of the connector one and block is equipped with integral type dregs guiding groove two.
Further, the cutter further includes medium guiding subassembly.
Further, the medium guiding subassembly includes being applied in diversion trench inside the handle of a knife and cutter hub, is arranged on week
Cavity on face and the intercommunicating pore for connecting diversion trench and cavity.
Further, the diversion trench is U-shaped structure.
The advantageous effects that the present invention is reached：Drilling tool provided by the invention,.
Brief description of the drawings
Fig. 1 schematic structural views of the invention.
Wherein：1 operator；2 auxiliary knives；3 side faces；4 dregs guiding grooves one；5 cavitys；6 intercommunicating pores；7 modification knife faces；8 modification blades；
9 connectors one；10 dregs guiding grooves two；11 blocks；12 connectors two；13 adapters；14 diversion trenches；15 main handles.
Embodiment
With reference to specific embodiment, the invention will be further described.Following embodiments are only used for clearly illustrating
Technical scheme, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
Patent of the present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, the present invention provides a kind of drilling tool, including cutter hub and handle of a knife；
The cutter hub includes cutter head, blade and trimming knife, and the cutter head includes being arranged on the operator 1 of blade end and auxiliary
Knife 2, the blade are made of helical form dregs guiding groove 1 and side face 3, and the auxiliary knife 2 is fixed on the end of the side face 3, institute
The one end for stating trimming knife is fixed on the other end of the blade, and the trimming knife includes umbrella-type modification knife face 7 and with modifying knife face
Integrally formed modification blade 8, the other end of the trimming knife are fixed on connector 1, and the handle of a knife end is equipped with connection
Part 2 12, the connector 1 are the cylinder with circular groove, and the connector 2 12 is size and the circular groove
The cylinder of matching, the cutter hub are fixed together by the inserting mode of connector 1 and connector 2 12.
Cutter head by operating and aiding in knife to form, and aid in knife be distributed in around operator, so when in use, operate into
While row drilling, auxiliary knife device to hole around operator carries out widening cutting, substantially increases drilling efficiency.In blade and handle of a knife
Between be equipped with and be used for modifying the trimming knifes of bore edges, the technical barrier for solving bore edges flange in the prior art.
The handle of a knife includes integrally formed main handle 15 and block 11, cross-sectional area and the connector of the block 11
One 9 cross-sectional area is equal, can reinforce the connection between connector 1 and handle of a knife.
Integrally formed adapter 13, the cross section of the adapter 13 are equipped between the main handle 15 and the block 11
Cross-sectional area, cross-sectional area more than the main handle 15 of the product less than the connector 2 12.The connector 1 and block 11
Surface be equipped with integral type dregs guiding groove 2 10, in use, chip pass through dregs guiding groove 1 enter modification blade between gap enter
Dregs guiding groove 2 10, is discharged from dregs guiding groove 2 10.
The cutter further includes medium guiding subassembly.The medium guiding subassembly includes being applied in the handle of a knife and cutter hub
