Description
Technical field
The present invention relates to metal cutting technology field, more particularly to a kind of drilling machining cutter.
Background technology
Drilling machining cutter is mainly cutting end part and bears cutting force when cutting, helicla flute and finished surface form enclosed area
Domain, chip can only be discharged from cutting end part through helicla flute, and chip removal is difficult, in order to ensure the working depth in hole, drilling processing
Tool in Cutting end typically has larger overhanging, and when cutting end part unbalance stress, cutting end part can be produced compared with the shank of clamping
Big amount of deflection, at the same when chip can not pole when discharge workpiece outside, the chip for accumulating and helicla flute, finished surface are formed and acutely scraped
Extruding is wiped, cutter hub can not only reduce machined surface quality, and can make drilling because circumferential stress is unbalance so as to produce vibration
The process tool life-span is greatly reduced.
In the prior art, in order to reduce cutter use cost, drilling machining cutter is generally designed into split-type structural, end
Cutting zone is separated from cutter hub and forms single cutting unit, and clamping part independently forms cutter hub, the repeatable handling of cutting unit
In on cutter hub, cutting unit is made up of inner blade, outer blade two panels blade, is respectively completed the path central post region in hole, big footpath
The processing in circumferential circular row region, because drilling machining cutter requirement has blind hole working ability and one group of inner blade, outer set of blades
Conjunction is applied to various different-diameter drilling machining cutters, thus, the requirement of inner blade cutting edge is set across the central shaft of cutter, and
Outer blade is set adjacent to finished surface, by inner blade, outer blade unit into a complete cutting edge, due to such hole machined
Tool uses asymmetric cutting blade structure, the machining area that inner blade, outer blade are completed to differ, so that inner blade, outer blade
Circumferential stress relatively has much difficulty in healing weighing apparatus, and the moment of torsion produced during cutting is asymmetric, is also easy to produce deflection deformation and cutting vibration, causes to process Kong Zhi
Footpath error is big, machined surface quality is poor.
Inner cutting inserts, outer cutting insert are used with the square blade of a substantially linear tooth shape, due to that can reduce
Blade species, the drilling tool equipped with the blade is in industry used widely.But with cutting speed, cutting feed requirement
Raising, become big using the inside and outside cutting tip radial force gap of straight line tooth shape, during cutting easily there is deflection deformation in cutter hub,
Cause vibration aggravation, surface quality difference and processing dimension uniformity poor, simultaneously because drilling tool diameter specifications are more, for the ease of
Use and manage, a specification blade will complete the application of the different drilling tool of multiple diameter, radially moved by outer cutting insert
During dynamic change Tool in Cutting diameter, the amount of material removed difference of inside and outside cutting tip is amplified, inside and outside using straight line blade structure
The radial force of cutting tip is weighed compared with having much difficulty in healing and chip breaking effect is undesirable, easily causes machined surface quality, shape and size precision
The problems such as difference, chip removal be not smooth, blade cut performance inconsistency is big.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, there is provided one kind incision stabilization, cutting vibration
Small, machined surface quality drilling machining cutter.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of drilling machining cutter, including cutter hub, the cutter hub include shank, cutting end part and positioned at the shank, cutting
Side face between end, on the substantially symmetrical about its central axis of the cutter hub, the cutting end part is provided with and week for the shank, side face
Central channel and circumferential slot that helicla flute on face is communicated, the central channel are set adjacent to central shaft, and the circumferential slot is adjacent to side face
Set, identical hole machined blade is equiped with the central channel and circumferential slot, the hole machined blade includes being in quadrangle
The blade body of tabular, the blade body is surrounded by the side of upper surface, lower surface and connection upper and lower surface, institute
State upper surface and side and be crossed to form four identical main cutting edges and the cutting of four turnings between adjacent major cutting edge
Sword, is installed in the hole machined blade in the central channel for inner blade, and the hole machined blade for being installed in the circumferential slot is outer knife
The main cutting edge of piece, the main cutting edge of the inner blade and the outer blade combines the complete cutting edge to be formed for processing hole,
The main cutting edge is provided with waveform cutting edge in wave shape in the lateral direction, during processing, in the central shaft side of the cutter hub
Upwards, the waveform cutting edge of the inner blade continuously cuts workpiece, and the waveform cutting edge of the outer blade discontinuously cuts workpiece.
As the further improvement of above-mentioned technical proposal：
The main cutting edge includes linear cutting edge and curved arc milling sword on the direction of upper surface, the waveform cutting
The crest of sword is respectively positioned on the arc milling sword.
The main cutting edge of the inner blade produces overlap around the rotation of the central shaft and the main cutting edge of the outer blade
Cutting zone, in the region, the linear cutting edge of inner blade prior to the outer blade arc milling sword and absorption surface and
Minimum preferential distance is d on central axis direction, and is met：0.02mm≤d≤0.3mm.
The waveform cutting edge includes multiple identical waveform elements, and the waveform element includes crest, trough and position
Ripple tooth between crest, trough, on the upper surface direction, the crest, trough are circular arc line, and the ripple tooth is straight
Line.
When the outer blade participates in the waveform cutting edge incision workpiece of cutting, on the central axis direction, the waveform
Unit discontinuously cuts workpiece.
Be provided between the arc milling sword and adjacent comer cutting edge tooth shape it is different with the arc milling sword
Three cutting edges, length of the 3rd cutting edge on the main cutting edge bearing of trend is H, and is met：0.2mm≤H≤
1.2mm。
3rd cutting edge of the outer blade adjacent bores finished surface is parallel with central shaft on the direction of rotation of central shaft,
And the 3rd the ultimate range of cutting edge and hole surface be d1, should meet：0.002mm≤d1≤0.03mm.
