Description
Technical field
The utility model belongs to cutting-tool engineering field more particularly to a kind of cylinder cap fuel injector aperture knife tool.
Background technique
In cylinder head preparation, the processing of the oil injector hole in cylinder head is needed with slotting cutter, cornish bit and rose reamer.It is first
First oil injector hole inner wall is milled one time with slotting cutter, circular hole is then diffused into designed size with cornish bit, it then will with rose reamer
Chamfering is made on the outside of oil injector hole.Above-mentioned preparation method has the following deficiencies: first, the above method needs three process, processing
Low efficiency, processing cost is high, energy waste is serious；Second, the row of universal cutter deep since oil injector hole diameter is small, and relatively
Bits slot is V-shaped, and waste iron filing is readily retained in chip space, it is not easy to be discharged, with the increase of the waste iron filing in chip space, give up
Iron filings between blade and cavity wall, can cause the inner wall of cavity wall with scratch, and finish is poor, increase the resistance of cutter rotation
Power wastes the energy, but also will cause the damage of cutter.
Utility model content
The technical problems to be solved in the utility model be just to provide it is a kind of it is high in machining efficiency, processing cost is low, energy consumption
Less, the good cylinder cap fuel injector aperture knife tool of the finish of the inner wall of long service life, cavity wall.
To solve the above problems, the technical solution that the utility model cylinder cap fuel injector aperture knife tool uses are as follows: including
Knife tail, cutter hub and cutter head, it is characterised in that: the cutter head includes preceding cutter head, middle cutter head and rear blade；Before the preceding cutter head includes
The section of blade before bit body, at least two, the preceding bit body is gear-like, and the preceding blade is fixed on nipper,
Front clearance slot is formed between the blade side and adjacent nipper of the preceding blade；The middle cutter head includes middle bit body, extremely
The section of few two middle blades, the middle bit body is gear-like, and the middle blade is fixed on middle tooth, the middle blade
Chip space in being formed between blade side and adjacent middle tooth, with jagged on the middle tooth of the blade side far from middle blade；
The rear blade includes rear blade ontology and rear blade, and the rear blade is fixed on rear blade ontology, the blade of rear blade
Chip space after being formed between side and adjacent rear tooth, the rear blade includes straight knife piece and oblique blade.
Its additional technical feature are as follows:
The preceding blade is four, and the middle blade is two.
Cylinder cap fuel injector aperture knife tool provided by the utility model compared with prior art, has the advantage that
First, due to including knife tail, cutter hub and cutter head, it is characterised in that: the cutter head includes preceding cutter head, middle cutter head and rear blade；Institute
Cutter head includes blade before preceding bit body, at least two before stating, and the section of the preceding bit body is gear-like, the preceding blade
It is fixed on nipper, forms front clearance slot between the blade side and adjacent nipper of the preceding blade；The middle cutter head includes
The section of middle bit body, blade at least two, the middle bit body is gear-like, and the middle blade is fixed on middle tooth
On, chip space in formation between the blade side of the middle blade and adjacent middle tooth, in the blade side far from middle blade
With jagged on middle tooth；The rear blade includes rear blade ontology and rear blade, and the rear blade is fixed on rear blade ontology
On, chip space after being formed between the blade side of rear blade and adjacent rear tooth, it is described after blade include straight knife piece and oblique blade,
During advance, the function of slotting cutter was both realized, but also the function of reaming can be played, in rear blade close to cylinder head
When surface, with the advance of cutter, chamfering is formed on the outside of oil injector hole, a procedure is completed at the same time three functions, processing effect
Rate greatly improves, and has saved the energy, with jagged on the middle tooth of the blade side far from middle blade, so that far from middle blade
In blade side under chip removal trough slope, in cutter rotation process, waste iron filing is easy to be discharged, and avoids waste iron filing and is deposited in
Between middle chip space and blade and cavity wall, the energy is saved, the inner wall of cavity wall is more smooth；Second, due to the preceding blade
It is four, the middle blade is two, and waste iron filing discharge is more thorough.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model cylinder cap fuel injector aperture knife tool；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the B-B sectional view of Fig. 1.
Specific embodiment
With reference to the accompanying drawings and detailed description to the structure of the utility model cylinder cap fuel injector aperture knife tool and
It is described in further details using principle.
As shown in Figure 1, Figure 2 and Figure 3, the structural schematic diagram of the utility model cylinder cap fuel injector aperture knife tool, this reality
It include knife tail 1, cutter hub 2 and cutter head 3 with novel cylinder cover oil injector hole process tool, cutter head 3 includes preceding cutter head 4,5 and of middle cutter head
Rear blade 6；Preceding cutter head 4 includes blade 42 before preceding bit body 41, at least two, and the section of preceding bit body 41 is gear-like,
Preceding blade 42 is fixed on nipper 43.Front clearance slot 45 is formed between 44 side of blade of preceding blade 42 and adjacent nipper.In
Cutter head 5 includes blade 52 in middle bit body 51, at least two, and the section of middle bit body 51 is gear-like, and middle blade 52 is solid
It is scheduled on tooth 53, chip space 55 in formation between 54 side of blade and adjacent middle tooth of middle blade 52, far from middle blade
With jagged 56 on the middle tooth 53 of 52 54 side of blade.Rear blade 6 includes rear blade ontology 61 and rear blade 62, rear blade 62
It is fixed on rear blade ontology 61, formation and chip space 65 between 63 side of blade and adjacent rear tooth 64 of rear blade 62, after
Blade 6 includes straight knife piece 7 and oblique blade 8.During advance, the function of slotting cutter was both realized, but also expansion can be played
The function in hole, with the advance of cutter, forms chamfering when rear blade is close to cylinder cap surface on the outside of oil injector hole, together
Process is completed at the same time three functions, and processing efficiency greatly improves, and has saved the energy.Middle tooth in the blade side far from middle blade
Upper band is jagged, so that in cutter rotation process, waste iron filing holds very much in the blade side far from middle blade under chip removal trough slope
It is easily discharged, avoids waste iron filing and be deposited between middle chip space and blade and cavity wall, saved the energy, the inner wall of cavity wall is more
Add smooth.
Preceding blade 42 is four, and middle blade 52 is two, and waste iron filing discharge is more thorough.
The protection scope of the utility model is not limited solely to above-described embodiment, as long as structure and the utility model cylinder head
Oil injector hole process tool structure is same or similar, just falls in the range of the utility model protection.
