Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
As shown in Figure 1, the profile milling cutter for processing groove is used to process slot, the shape of slot such as Fig. 3 institute in workpiece surface
Show.
The definition left side Fig. 1 is front, the right is rear.
It as shown in Figure 1 and Figure 2, include knife handle 1 and cutter head 2 for the profile milling cutter of processing groove.Knife handle 1 for lathe at
The clamping of type milling cutter, cutter head 2 is for cutting workpiece.Running through in knife handle 1 and cutter head 2 has interior cold hole 3, interior cold 3 nothing of hole
Zhi Kong, interior cold hole 3 are through to the front end of cutter head 2 from the rear end of knife handle 1.Cutting fluid is imported into the slot of processing by interior cold hole 3,
Be conducive to cooling and row to cut.
1 back segment of knife handle is coarseer than leading portion, and back segment clamps profile milling cutter for lathe, and leading portion is used to support cutter head 2.
Cutter head 2 includes pedestal 21 and cutting unit 22.Cutting unit 22 is arranged in 21 border of pedestal.Pedestal 21 is used to support
Cutting unit 22.Pedestal 21 and knife handle 1 are integrally formed.In the present embodiment, there are three cutting unit 22(it is, of course, also possible to be one
A, two, the cutting unit of four or more), each cutting unit 22 includes 3 blade 221(it is, of course, also possible to be 2,4
A or more blade), the blade 221 in the same cutting unit 22 processes the same slot.The cutting list of 21 front and back ends of pedestal
Member 22 processes square groove (such as Fig. 3), and intermediate cutting unit 22 processes dovetail groove (such as Fig. 3) on pedestal 21.
As shown in figure 4, Fig. 4 shows the floor map of three groups of blades, i.e. (one) group, (two) group and (three) group, often
(namely the cutting by three blades 221 that group blade is made of the cutting edge of a blade 221 in three cutting units 22
Sword composition).Chain-dotted line in figure in every group is the axial line of profile milling cutter.
Such as Fig. 4, might as well define Far Left in every group is the first cutting unit, and centre is the second cutting unit, and rightmost is
Third cutting unit.
First cutting unit, third cutting unit process square groove, and the second cutting unit processes dovetail groove (such as Fig. 3).?
In one cutting unit, corresponding blade one slot of preliminary working in (two) group and (three) group, the width of slot has not been reached yet scheduled
Width, in (one) group corresponding blade in (two) group and (three) group blade 221 to the processing of slot on the basis of increase the width of slot
Degree.In the first cutting unit, that is, (one), (two), the corresponding blade of that blade of Far Left in (three), blade in (one)
The depth of processing groove does not have that (two), the depth of blade processing groove is big in (three), i.e., (two), Far Left blade adds slot in (three)
Work increases the depth of slot on the basis of being the Far Left blade processing groove in (one).
Certainly, in other technical solutions of the utility model, Far Left blade processing groove in (one) can also be set
Depth of the depth slightly larger than Far Left blade processing groove in (two), (three) group.Far Left blade adds slot in (one) group in this way
Work is exactly the width and depth for increasing slot on the basis of Far Left blade processing groove simultaneously in (two), (three) group.
The face a is respectively as follows: in (one) from " l " with a distance from profile milling cutter axial line in the second cutting unit, in figure is
6.5mm is 6.5mm in (two), is 6.7mm in (three), the blade 221 in (three) in corresponding second cutting unit is in dovetail groove
0.2mm is deepened at middle a, i.e., in same second cutting unit, the blade 221 in (three) is the blade in (one), (three)
The depth at dovetail groove a is deepened on the basis of the dovetail groove of processing, has made to have deepened 0.2mm at dovetail groove a.Certainly, (three) group
The right inclined cutting blade portion (namely the inclined-plane in the neighbouring face a) of intermediate blade 221 increase simultaneously dovetail groove width and
Depth.
The increase of increase or width either to the depth of slot is the cutting to the dimension enlargement of slot.Single institute
It states in cutting unit 22, it to be size on the basis of processing of another blade 221 to slot to the processing of slot that there are a blades 221
Widened cutting, this advantageously reduces the cutting resistance of blade；The either same cutting unit 22 preceding cutting blade also
It is the blade in rear cutting, can reduces the cutting resistance of the blade；Preceding cutting blade due to not having to slot time processing
To scheduled size, it only need to be worked into the size of a depth or reduced width, therefore cutting resistance can be reduced；In rear cutting
Blade due to only need preceding blade processing on the basis of to slot carry out size expansion, so can reduce cutting resistance
Power.The reduction of cutting resistance is conducive to improve processing efficiency and improves processing quality.
As shown in Figure 1, the side set on circumference is presented in the sword exterior feature of blade 221 using the direction of axis line of profile milling cutter as sight
Blade 221 in setting, namely different cutting unit 22 will not cutting workpiece simultaneously, always there is a time difference.Such as most
A blade 221 on the cutting unit 22 on the right starts cutting workpiece, and at this moment there are no blades 221 on intermediate cut unit 22
Workpiece is touched, after rightmost cutting unit 22 that blade 221 has cut a period of time or has completed cutting,
There is blade 221 just to touch workpiece on intermediate cut unit 22 and starts to cut.Such side set setting advantageously reduces whole
The cutting resistance of body formed milling cutter is conducive to further increase processing efficiency and processing quality.
As depicted in figs. 1 and 2, chip space 211, rake face of the chip space 211 adjacent to blade 221 are additionally provided on pedestal 21
2211, chip space 211 extends to 1 circumferential surface of knife handle.Being provided with for chip space 211 is conducive to discharge cutting.
As depicted in figs. 1 and 2, further, the axial line of the rake face 2211 neighbouring with chip space 211 and profile milling cutter
Between form angle, the formation of angle is more advantageous to export cutting, improves processing efficiency.
In the present embodiment, knife number is identical in each cutting unit 22, is 3, this is conducive to improve profile milling cutter
Dynamic balancing.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
