Description
Technical field
The present invention relates to machine tool field more particularly to a kind of boring hinge composite blades and cutter.
Background technique
In the finishing mode in current hole, by the way of generally being processed using boring or reamer, then it is more demanding when,
Using the Combined machining of the two.Boring processing is suitable for the processing of larger aperture, but its finishing is general by the way of single-blade,
Can just be effectively ensured the size and shape precision of processing, but since it is single-blade processing, efficiency is lower, surface roughness by
Its point of a knife fillet and feeding are affected, but bore hole can correct asking for the hole site low precision that preamble processing carries over
Topic.And traditional reamer, size-constrained, its manufacture difficulty of the reamer of larger size and economy are very poor, will lead to processing
Cost is high, but is also obvious the advantages of ream: high-efficient, form tolerance is good, and surface quality is excellent, still
Reamer cannot correct the problem of the position degree difference in hole caused by preamble processing.
Existing Compound Machining is usually two procedures, first presses boring processing arrangement technique, and the position of related features of trimming hole is stayed
Suitable reaning allowance, then one of ream process is arranged, guarantee the size and shape precision in hole.It so arranges, processing needs
Two procedures, the requirement to lathe and people has higher requirements, while efficiency also can decrease.The reamer system of another larger size
It is also higher to make also difficulty, cost.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of blade that can be achieved at the same time boring and ream.
In order to solve the above problem the technical solution adopted is that: boring cut with scissors composite blade include cutter blade, be provided on cutter blade
Boring structure and ream structure positioned at boring structure rear；After boring structure includes boring cutting edge and is located at boring cutting edge
The boring chip-breaker of side, 5 °≤λ≤25 ° of cutting edge inclination of boring cutting edge, 30 °≤Kr≤90 ° of tool cutting edge angle of boring cutting edge, boring
Cut 45 °≤β≤90 ° in inclination angle of the chip breaking reverse slope of chip-breaker；Ream structure includes ream support sword, and ream support sword is located at boring
Cut the outside in blade tip portion.
Further, ream support sword and boring cutting edge tip distance 0.025mm≤X≤0.5mm.
Further, ream structure include positioned at ream support sword in front of ream cutting edge, be located at ream support sword
The anti-scratch chamfering at rear and the ream chip-breaker on the inside of ream support sword.
Another technical problem to be solved by the present invention is that: a kind of blade can be achieved at the same time boring and ream is provided.
In order to solve the above problem the technical solution adopted is that: boring cut with scissors compound tool include cutter hub, be connected at least on cutter hub
Composite blade is cut with scissors in two borings, and boring cuts with scissors composite blade using cutter hub axis as center circumference uniform distribution.
The beneficial effects of the present invention are: 1, boring hinge composite blade has merged boring structure and ream structure enables blade
Boring and ream machining are realized simultaneously.The parameter of boring structure and ream structure is in zone of reasonableness, so that boring was cut
Cutting is discharged forward, avoids having an impact ream and scratching the smooth finish surface that ream obtains.
2, multiple boring hinge composite blades are connected on cutter hub, realize multiple tooth processing, effective raising efficiency.Since blade can be more
It changes, can easily realize the design and manufacture of larger spot facing cutter, reduce the manufacture difficulty and cost of cutter.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figures 1 to 7: it includes cutter blade 1 that composite blade is cut with scissors in boring, and boring structure 2 is provided on cutter blade 1 and is located at
The ream structure 3 at 2 rear of boring structure；Boring structure 2 includes boring cutting edge 21 and the boring positioned at 21 rear of boring cutting edge
Cut chip-breaker 22,5 °≤λ≤25 ° of cutting edge inclination of boring cutting edge 21,30 °≤Kr≤90 ° of tool cutting edge angle of boring cutting edge 21, boring
Cut 45 °≤β≤90 ° in inclination angle of the chip breaking reverse slope of chip-breaker 22；Ream structure 3 includes that ream supports sword 32, and ream supports sword
32 are located at the outside of 21 tip of boring cutting edge.
It wherein, is the boring hinge composite blade of paperback shown in Fig. 1 to Fig. 6.It is to found the boring hinge composite blade filled shown in Fig. 7, two
Person's structural parameters are identical.
Boring hinge composite blade installs multiple borings hinge composite cutters in use, as shown in figure 8, be installed on cutter hub 5 on cutter hub 5
Piece forms boring hinge compound tool.Mounting means is the setting mounting hole 4 on cutter blade 1, and composite cutter is cut with scissors in boring by fastener
Piece is fixed on cutter hub 5.
Boring hinge composite blade has merged boring structure 2 and ream structure 3 makes blade can be achieved at the same time boring and ream
Processing.The parameter of boring structure 2 and ream structure 3 is in zone of reasonableness, so that the cutting that boring is cut is discharged forward, is avoided
The smooth finish surface that ream obtains is had an impact and scratched to ream.Multiple boring hinge composite blades are connected on cutter hub 5, realize multiple tooth add
Work, effective raising efficiency.
After boring processing, it should which there are a small amount of surpluses to ream machining, therefore ream support sword 32 is located at boring cutting edge
The outside of 21 tips, ream supports sword 32 and 21 tip distance 0.025mm≤X of boring cutting edge≤0.5mm, to guarantee ream
It is machined with suitable processing capacity.
The other parameters of boring structure 2, such as anterior angle γ, relief angle α are identical as existing boring cutter blade.Boring structure 2 its
His structure is identical as existing boring cutter, and ream structure 3 includes positioned at the ream cutting edge 31 in 32 front of ream support sword, positioned at ream
Support the anti-scratch chamfering 33 at 32 rear of sword and the ream chip-breaker 34 positioned at 32 inside of ream support sword.Ream cutting edge 31 rises
Shear action, ream support sword 32, which serves, squeezes smoothing, and anti-scratch chamfering 33 avoids scratching machined surface.Ream supports sword 32
Flank can be plane and be also possible to arcwall face.The parameter of boring structure 2, such as inclination angle a, the ream branch of ream cutting edge 31
