The assembly efficiency and yield of a workpiece are lower.
Therefore, a kind of boring cutter that can be processed and formed at one time stepped hole simultaneously of people's urgent need, to solve the prior art
In multiple single bore hole boring cutters cut possessed by drawbacks described above.
Utility model content
Technical problem to be solved in the utility model are as follows: a kind of ladder hole machined boring cutter is provided, the prior art can be overcome
Middle processing shoulder hole needs the problem of multiple single bore hole boring cutter cooperation processing, to overcome low efficiency in ladder hole machined, produce
Can be low, at high cost, it cuts a stepped hole needs and takes considerable time, and cause the assembly efficiency of entire workpiece and yield lower
Defect.
Used technical solution is to solve above-mentioned technical problem:
A kind of ladder hole machined boring cutter, including mounting head, knife handle, cutter head, boring blade, the mounting head, knife handle and cutter head
Be one of the forming part, and the mounting head is used to for boring cutter being installed on milling machine shaft, and the cutter head has multiple and all along knife handle
To being uniformly distributed, the cutter head has the ladder of at least two ranks, and each ladder side of cutter head is mounted on boring blade, the boring
Blade is cut along hole inner wall to be processed direction.
In a preferred embodiment, the knife handle is cylinder, and there are four the cutter heads, and cutter head is along knife handle circle
Cylindricality is circumferentially uniformly distributed.
In a preferred embodiment, the cutter head has the ladder of three ranks.
In a preferred embodiment, the boring blade includes heavy boring blade and half right boring blade, at least one
Each ladder side of cutter head is mounted on heavy boring blade, is mounted on half fine boring cutter in each ladder side of remaining cutter head
Piece.
In a preferred embodiment, it is respectively mounted heavy boring blade on two opposite cutter heads, in other two phase
To being respectively mounted half right boring blade on cutter head.
In a preferred embodiment, the ladder side of the cutter head has insert groove, and the insert groove is set to
The side of each ladder of cutter head, the boring blade is embedded in corresponding insert groove, and the insert groove has notch on one side, to protect
The side blade for demonstrate,proving boring blade exposes insert groove.
In a preferred embodiment, the boring blade is fixed in insert groove using screw.
The beneficial effects of the utility model are: by the way that multiple cutter heads are arranged on knife handle, and cutter head has at least two ranks
Ladder, ladder height are gradually decreased along direction of feed, and each ladder side of cutter head is mounted on boring blade, to guarantee one
In secondary aperture process, the ladder of sustained height cuts to form same aperture, and different pore size forms stepped hole.The utility model institute
Stepped hole can be processed and formed at one time by stating boring cutter, without multiple single bore hole boring cutter cooperations, to greatly improve the effect of hole machined
Rate and production capacity, and reduce cost, shorten the time of cutting stepped hole, thus greatly improve one-piece machine member assembly efficiency and
Yield.
Detailed description of the invention:
Fig. 1 is: the perspective view of boring cutter described in the utility model；
Fig. 2 is: the side view of boring cutter described in the utility model；
Fig. 3 is: explosive view of the boring cutter described in the utility model at cutter head；
Fig. 4 is: the partial enlarged view of the insert groove of boring cutter described in the utility model.
Each appended drawing reference in figure are as follows: 1: mounting head, 2: knife handle, 21: cutter head, 211: insert groove, 3: boring blade, 31: heavy boring
Blade, 32: half right boring blades, 4: screw.
Specific embodiment:
Below with reference to each attached drawing, the utility model is described in detail.
As shown in Figure 1, boring cutter described in the utility model includes mounting head 1, knife handle 2, cutter head 21 and boring blade 3, the peace
Dress head 1, knife handle 2 and cutter head 21 are one of the forming structure, can fully ensure that the stability of boring cutter structure, increase boring cutter to big cutting
The ability to bear of power, and mounting head 1 and knife handle 2 using it is integrally formed can avoid as hole internal friction it is excessive caused by dally
It does not cut.The cutter head 21 has the hierarchic structure of three ranks, and ladder height is gradually decreased along direction of feed, and in each cutter head 21
Ladder side be fixed with boring blade 3.
As shown in Fig. 2, knife handle 2 is cylinder, 4 cutter heads 21 are being evenly distributed with along cylindrical circumferential.Using above-mentioned knot
Structure can guarantee that each cutter head 21 is acted on by uniform and identical cutting force, to keep the surface roughness for the stepped hole to be formed equal
Even, circularity is more preferable.
As shown in figure 3, heavy boring blade 31 is fixedly installed in each ladder side of two opposite cutter heads 21, at remaining
Each ladder side of two cutter heads 21 is equipped with half right boring blade 32, and the heavy boring blade 31 and half right boring blade 32 are respectively mounted
In in insert groove 211, and it is fixed with screw 4.After using heavy boring blade 31 and the setting of half right boring blade 32 interval, formed compound
Type boring cutter combines the roughing of stepped hole and finishing, further increase the processing efficiency and yield of stepped hole, shortens and adds
Between working hour.
As shown in figure 4, there is the insert groove 211 of certain depth in each ladder side of cutter head 21, and insert groove 211 exists
The upper on one side of direction of feed has opening, when installing or replacing boring blade 3, boring blade 3 is embedded in insert groove 211, i.e. knife
The size of film trap 211 corresponds to corresponding boring blade 3, so that boring blade 3 be made to be embedded in insert groove 211.In replacement boring blade 3 every time
When, it is ensured that the position of boring blade 3 is constant, does not need to re-measure size with to knife, tool changing is convenient and efficient, can greatly save work
The measurement of people's tool changing with to the knife time.
The above is only the preferred embodiment of the present invention, not thereby limits the patent protection of the utility model
Range, it is all with equivalent structure transformation made by the utility model specification and accompanying drawing content, directly or indirectly it is used in it
His relevant technical field similarly includes within the protection scope of the present utility model.
