The invention has the beneficial effects as follows: the present invention is by using the cutter structure of twolip cutting so that cutter can be once
Property process the profile of boss, and due to dismountable broach shell and blade, therefore use the broach shell of different model and specification with
Blade just can process the boss of required various profiles, also has only to more allowing blade replacement when wear and aging occurs in milling cutter, significantly
Reduce operation and cost.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is milling cutter construction schematic diagram of the present invention；
Fig. 2 is milling cutter right view of the present invention；
Fig. 3 is milling cutter fundamental diagram of the present invention.
Detailed description of the invention
The milling cutter shaped for boss as shown in Figure 1-2, including knife bar 1 and broach shell 2, knife bar 1 rear portion is provided with and lathe phase
Connecting portion even, this connecting portion is provided with flat key groove, and knife bar 1 is fixed on the scroll chuck of lathe and by machine by this connecting portion
Bed main shaft drives.
Broach shell 2 rear portion is a hollow ring structure, makes broach shell 2 can be set in knife bar 1 anterior, it is ensured that knife bar 1 and cutter
Overlapping 2 concentrics, for removably connecting between broach shell 2 and knife bar 1, the hollow ring structure of broach shell 2 is provided with two handle of a knifes 3.
Above-mentioned handle of a knife 3 is circular arc platy structure, and its thickness is equal with hollow ring thickness, the Knife handle structure energy of circular arc
Enough strengthening the working strength of handle of a knife 3, the front end of two handle of a knifes 3 is respectively provided with dismountable main blade 4 and auxiliary-blade 5, main blade 4
As auxiliary-blade 5 symmetrical for line of symmetry with the common axis line of broach shell 2 with knife bar 1, and two blades all with knife bar 1 and cutter
The common axis line of set 2 be arranged in parallel, it is ensured that during milling, two blades are with the direction feeding of the most to be processed, it is ensured that
Big work efficiency.
In the present embodiment, main blade 4 uses diamond shaped insert, mainly processes between basic profile and the boss of boss
Plane；Auxiliary-blade 5 uses circular knife, mainly processes the excessive fillet on boss, and the milling radius of auxiliary-blade 5 is relative to main blade
4 is slightly smaller.
Preferably, main blade 4 is all connected with handle of a knife 3 by blade screw with auxiliary-blade 5, and insert screw is high intensity
Screw, it is possible to ensure the blade stability when milling, be also convenient for removing and installing of blade simultaneously.
Preferably, knife bar 1 is connected by two flat keys 7 with broach shell 2, by flat key 7, the kinetic energy of lathe is delivered to broach shell 2
On.
Preferably, equipped with anti-return nut ring 8 on knife bar 1, anti-return nut ring 8 front end abuts in broach shell 2 rear end, to broach shell 2
The effect of support is played in rear end.
Preferably, threaded on knife bar 1 have round nut 9, and anti-return nut ring 8 is clamped between round nut 9 and broach shell 2,
Anti-return nut ring 8 is played the effect of fixing support, it is ensured that the stability that milling cutter is overall in milling process.
Preferably, floor clip 10 it is provided with between round nut 9 and anti-return nut ring 8.
The work process of above-mentioned milling cutter processing boss is as follows:
First choose broach shell 2, main blade 4 and the auxiliary-blade 5 being consistent with required processing boss specification, main blade 4 and auxiliary-blade 5 with
Respective handle of a knife 3 is connected, and then machine tool chief axis starts rotate and drive milling cutter to rotate, along with machine tool chief axis drives milling cutter feeding,
Main blade 4 processes the plane between basic profile and the boss of boss on workpiece to be added, due to the milling radius of auxiliary-blade 5
Main blade 4 relatively is slightly smaller, and auxiliary-blade 5 will process the excessive angle of boss circular arc on boss.
In preferred embodiment, with reference to Fig. 1, knife bar 1 nose threads connects guide post 6, guide post 6 with in advance to be added
The prebored hole phase configuration of processing on work face, guide post 6 external diameter is equal to or slightly less than the internal diameter of prebored hole.Guide post 6 external diameter is smaller
Refer in prebored hole internal diameter: both can guarantee that guide post inserts prebored hole smoothly, also can reduce shaking of cutter in the course of processing
Dynamic, improve the quality of processing.The guide post 6 of various outer diameter can be chosen according to the size of prebored hole simultaneously.
The work process of the milling cutter processing boss of this embodiment is as follows:
First choose the guide post 6 of appropriate size according to prebored hole internal diameter size and be connected with knife bar, outside selected guide post 6
Footpath equals to or slightly less than prebored hole internal diameter, chooses broach shell 2, main blade 4 and the auxiliary-blade being consistent with required processing boss specification
5, main blade 4 is connected with respective handle of a knife 3 with auxiliary-blade 5, is then directed to bar 6 by control machine tool chief axis feeding and stretches into preboring
Kong Zhong, after guide post 6 stretches into prebored hole, main shaft starts rotate and drive milling cutter to rotate, and main shaft continues to drive milling cutter feeding, feeding
During guide post 6 can reduce milling cutter vibration in the course of processing, along with the feeding of milling cutter, main blade 4 is at workpiece to be added
On process the plane between basic profile and the boss of boss, owing to the milling radius of auxiliary-blade 5 is slightly smaller relative to main blade 4,
Auxiliary-blade 5 will process the excessive angle of boss circular arc on boss.
The above is the preferred embodiment of the present invention, and it is not intended that limiting the scope of the invention.
