Description
Technical field
A kind of cutter structure is the utility model is related to, more particularly to it is a kind of simple in structure, stock-removing efficiency can be improved, reduces and bores
Head process time, so as to reduce the cutter structure for oval hole machined of cutter loss.
Background technology
In existing NC Machining Process, the processing of slotted hole is usually first processed with drill bit on the position of the hole of slotted hole
Go out 8 word holes, then ream is except the surplus that has more between two 8 word holes, such as using Φ 30U brills need Drilling operation and slotted hole both ends and in
Between at corresponding three, hole wall leaves residual side, it is necessary to call milling cutter to be removed again after processing, power of giving up when useless, and bores machined parameters
Slowly, simultaneously because processing using intermittent type, easily occur burning knife phenomenon, cutter loss is big, shortens cutting-tool's used life.
The content of the invention
The utility model mainly there is provided a kind of simple in structure, can improve stock-removing efficiency, reduce drill bit process time, from
And the cutter structure for oval hole machined of cutter loss is reduced, solve long processing time existing in the prior art, imitate
Rate is low, and cutter loss is big, shortens the technical problem of cutting-tool's used life etc..
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：One kind is used for oval
The cutter structure of hole machined, including handle of a knife and the tool apron arranged on handle of a knife front end, the tool apron are connected to handle of a knife for coaxial integrated
The elongated cylinder structure of front end, the outer ring surface both sides of tool apron front end extend to form right angle locating slot respectively inwards, in side clockwise
To right angle locating slot side on fixed diamond shape jack blade, acute ends of jack blade extend to right angle positioning
Outside groove, and two jack blades outer surface it is coplanar and through tool apron shaft core line.The tool apron of elongated cylinder structure and handle of a knife one
Body formula connects, and bonding strength is high, and tool apron use elongated cylinder, during oval hole machined, need to only pass through drill bit one circular hole of processing, knife
Tool can deeply carry out jack processing in drilling, process slotted hole is processed and formed at one time, simple in structure, processing without residual side
Efficient, cutter loss is small, cutter life length；The jack blade of diamond shape, four cutting edges are all fully utilized, and save
Manufacture and processing cost；Two jack blades are symmetrical and coplanar setting, uniform force during cutter use, improve hole and add
Work precision.
Preferably, right angle locating slot side corresponding with the jack blade is downwardly extending blade positioning groove, insert
Hole blade is fixed in blade positioning groove.Jack blade is fixed in blade positioning groove, and fixed form is simple and reliable.
Preferably, the tool apron length is 1.5 to 2 times of 1 length of handle of a knife.Tool apron has enough length, it is ensured that knife
Seat deeply carries out jack processing in drilling.
Preferably, the right angle positioning groove length is 45mm to 55mm, and the medial extremity of right angle locating slot and tool apron
The connection that smoothly transits is kept by arcwall face between outer ring surface.Right angle locating slot keeps smooth by the outer ring surface of arcwall face and tool apron
Transition, improves intensity, avoids stress concentration；Right angle positioning groove length keeps enough length, ensures that chip removal is suitable in process
Profit.
Preferably, the tool apron outer ring surface close to the handle of a knife is equipped with cutter model identification.Cutter model identification is used for
Cutter model is identified, is used easy to distinguish.
Therefore, a kind of cutter structure tool for oval hole machined of the utility model has the advantage that：Oval hole machined
When, only need to by drill bit process a circular hole, cutter deeply drill in can carry out jack processing, process slotted hole is without residual
Side, is processed and formed at one time, simple in structure, and processing efficiency improves 35%, and cutter loss is small, cutter life length；Tool apron keeps foot
Enough length, it is ensured that tool apron deeply drill it is interior progress jack processing.
Brief description of the drawings：
Fig. 1 is a kind of structure diagram of cutter structure for oval hole machined of the utility model；
Fig. 2 is the left view removed shown in Fig. 1 after jack blade.
Embodiment：
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment：
As depicted in figs. 1 and 2, a kind of cutter structure for oval hole machined of the utility model, including handle of a knife 1 and one
The tool apron 2 of the coaxially connected elongated cylinder structure in 1 front end of handle of a knife of body formula, the outer ring surface both sides of 2 front end of tool apron are symmetrically inwardly prolonged
Stretch to form right angle locating slot 3, the jack blade 4 of fixed diamond shape on the side of right angle locating slot 3 in the clockwise direction, with inserting
Corresponding 3 side of right angle locating slot of hole blade 4 is downwardly extending blade positioning groove 5, and jack blade 4 is fixed by flat head screw
In blade positioning groove 5, an acute ends of jack blade 4 are extended to outside right angle locating slot 3, and two jack blades 4 is outer
Surface co-planar and the shaft core line for passing through tool apron 2, the wherein length of handle of a knife 1 are 90mm, and the length of tool apron 2 is 155mm, and right angle positions
The length of groove 3 is 50mm, and keeps smooth mistake by arcwall face 6 between the outer ring surface of the medial extremity of right angle locating slot 3 and tool apron 2
Cross connection.For the ease of identifying cutter model, cutter model identification 7 is carved with 2 outer ring surface of tool apron of handle of a knife 1.
Specific embodiment described herein is only the design explanation for example to the utility model.The utility model
Person of ordinary skill in the field can do various modifications or additions or using class to described specific embodiment
As mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
