Fig. 1 is the dimensional structure diagram for the milling cutter that the utility model embodiment provides；
Symbol represents：
1- cutter bodies, 2- fixed seats, the locating slots of 3- first, 4- blades, the locating slots of 5- second, 6- grooves, 7- fixing holes.
Embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following description is related to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the utility model.On the contrary, they be only with such as
The example of the consistent apparatus and method of some aspects being described in detail in appended claims, of the present utility model.
Accompanying drawing 1 is refer to, accompanying drawing 1 shows the dimensional structure diagram for the milling cutter that the utility model embodiment provides.
The milling cutter that the utility model embodiment provides includes cutter body 1 and fixed seat 2, wherein, cutter body 1 is circle
Shape, fixed seat 2 are annular.Cutter body 1 is the body construction of milling cutter.Fixed seat 2 is the portion being fixed on milling cutter on knife bar
Part.Fixing hole 7 is set on the inside of the annulus of fixed seat 2, so that milling cutter is fixed on knife bar by fixing hole 7.To enable milling cutter
Fixed on knife bar, fixing hole 7 axially penetrates through fixed seat 2.Fixed seat 2 runs through the center of cutter body 1, and is embedded in milling cutter sheet
In body 1.Relative motion does not occur between cutter body 1 and fixed seat 2.
The periphery of cutter body 1 is provided with several the first locating slots 3.First locating slot 3 is used to fix blade 4, and then
It is easy to milling cutter to work pieces process.When first locating slot 3 places blade 4, the activity of blade 4 is positioned in the first locating slot 3.For ease of
The wedgewise of the first locating slot of placement 3 of blade 4.Workpiece is cut for ease of blade 4, the first locating slot 3 is arranged to inclined, i.e., and the
Angle between the center line of one locating slot 3 and the tangent line of cutter body 1 be present, and the center line of the first locating slot 3 is not orthogonal to
The tangent line of cutter body 1.Further, the angle of inclination of the first locating slot 3 is 75 °.When the angle of inclination of the first locating slot 3 is
At 75 °, the dynamics that blade 4 is acted on workpiece is relatively mild, will not produce deeper or shallower cut, is advantageous to workpiece and adds
Work.Further, for ease of by the installation and dismounting of blade 4, the first locating slot 3 perpendicular to two sides of cutter body 1 with
Two sides of cutter body 1 are connected, i.e., the first locating slot 3 leaks outside in cutter body 1.
Milling cutter runs at high speed under the drive of knife bar, if position distribution of the blade 4 on milling cutter is uneven, blade 4 is in height
Unbalance stress in the centrifugal motion of speed, cause blade 4 uneven to the cutting force degree of workpiece.Because blade 4 is to the cutting force of workpiece
Degree is uneven, thus the abrasion condition of blade 4 has differences, and then causes the workpiece within the regular hour to complete to process.For
The phenomenon that blade 4 wears inequality is avoided the occurrence of, is arranged in cutter body 1 symmetrical expression of the first locating slot 3 of fixed blade 4.
On same milling cutter, the quantity of the first locating slot 3 is even number.
In the milling cutter that the utility model embodiment provides, the periphery of cutter body 1 is provided with several the second locating slots
5.The shape of second locating slot 5 and the first locating slot 3, effect and quantity are identical.Likewise, the second locating slot 5 is also configured as
It is inclined.When the working depth of workpiece is deeper, to save process time, blade 4 needs once to mark deeper indentation, because
And the angle of inclination of the second locating slot 5 is 45 °.Based on the reason for identical with the setting of the first locating slot 3, the second locating slot 5
It is arranged in cutter body 1 symmetrical expression.On same milling cutter, the quantity of the second locating slot 5 is also even number.For ease of the second positioning
The arrangement of the locating slot 3 of groove 5 and first is set, and the second locating slot 5 is arranged at intervals successively with the first locating slot 3.It is fixed for ease of second
The interval setting of the position locating slot 3 of groove 5 and first and the use intensity for increasing cutter body 1, same second locating slot 5 are adjacent
Two the first locating slots 3 are different apart from the distance of second locating slot 5.
For ease of by the installation and dismounting of blade 4, the second locating slot 5 is perpendicular to two sides of cutter body 1 and milling cutter
Two sides of body 1 are connected.Further, the periphery of cutter body 1 is additionally provided with several grooves 6.Quantity of groove 6 etc.
In the first locating slot 3 and the summation of the quantity of the second locating slot 5.Groove 6 when setting, groove 6 respectively with the first locating slot 3 and the
The port of two locating slots 5 is in contact, in order to hand or it is other be affectedly bashful 4 one spaces of blade, and then can be relatively easy to tear open
Bottom knife 4.
Milling cutter provided by the utility model is fixed on knife bar by the fixed seat 2 of annular.The periphery of cutter body is set
Several locating slots 5 of the first locating slot 3 and second are equipped with, blade 4 is placed in the first locating slot 3.Several first locating slots 3
And second locating slot 5 be symmetrical arranged in cutter body, and the first locating slot 3 and the second locating slot 5 are arranged at intervals successively,
And then blade unbalance stress because of position asymmetry when milling cutter rotates can be prevented, avoid that blade is lost and influences workpiece to add
Work.Two sides of the side of first locating slot 3 and the second locating slot 5 with cutter body 1 are connected, in order to from milling cutter sheet
Removal of inserts 4 on body 1.Because blade 4 is movably arranged in the first locating slot 3 and second locating slot 5, thus when blade 4 is sent out
More allowing blade replacement 4 is only needed during raw abrasion, it is not necessary to changes whole milling cutter.The cost of blade 4 is far below the cost of milling cutter, because
And the cost of milling cutter can be reduced.
Those skilled in the art will readily occur to this practicality after considering specification and putting into practice the disclosure of utility model here
New other embodiments.The application is intended to any modification, purposes or adaptations of the present utility model, these
Modification, purposes or adaptations follow general principle of the present utility model and including undocumented skills of the utility model
