Abstract
The utility model discloses a kind of milling cutter, comprise handle of a knife and cutter head, described handle of a knife is connected by optical axis with between cutter head, and the diameter of optical axis is less than the diameter of cutter head, and handle of a knife, optical axis and cutter head offer mutually through cooling liquid flowing channel along axis.The utility model is less than the optical axis of cutter head by arranging diameter, improve the rigidity of milling cutter, milling cutter is extended service life, does not need often to change milling cutter, and can process with more speed, improve working (machining) efficiency.Be provided with cooling liquid flowing channel, can coolant be saved, improve cooling effect, extend cutter head service life.
Description
Technical field
The utility model belongs to Machining Technology field, particularly relates to a kind of milling cutter.
Background technology
At present, industrial circle, when the narrow deep trouth of milling, often uses general elongated blade milling cutter.This milling cutter only includes cutter head and handle of a knife, in the occasion that some are more special, e.g., when the deep trench that the milling of disjunctor volute higher slice is not only narrow but also dark, there is larger defect.General elongated blade milling cutter holds bits property to fully ensure, so cutter head flute is comparatively dark, like this, sword core is comparatively thin, causes the rigidity of milling cutter greatly to reduce, and easily fracture man-hour adding, and the roughness of finished surface is large, processing effect is poor.Meanwhile, in order to reduce the concept that milling cutter fractures, extend the milling cutter life-span, adding the process velocity having to man-hour reduce milling cutter, cause the time of processing work long, efficiency is low.
In addition, generally all need to cool milling cutter in Milling Machining, common way is exactly an external coolant pipe, add cooling fluid at milling cutter place to cool, such complex structure, not easily the consumption of cooling fluid is regulated and controled, and the consumption of cooling fluid is very large, causes the waste of some cooling fluids.Also have present milling cutter to install when fixing, more difficult when dismantle, otherwise be exactly that milling cutter is fixed unstable, easily appearance is loosening, causes serious accident.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Utility model content
The purpose of this utility model is just to provide a kind of milling cutter, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model is realized by following technical proposals:
A kind of milling cutter, comprise handle of a knife and cutter head, described handle of a knife is connected by optical axis with between cutter head, and the diameter of optical axis is less than the diameter of cutter head, and handle of a knife, optical axis and cutter head offer mutually through cooling liquid flowing channel along axis.
As preferably, the spiral angle of described cutter head has at least two kinds of angles of inclination, and the spiral angle of milling cutter bottom is greater than the spiral angle on milling cutter top.
As preferably, described handle of a knife surface offers annular groove.
As preferably, the length of described optical axis is greater than the length of cutter head.
Compared with prior art, the beneficial effects of the utility model are:
1. being less than the optical axis of cutter head by arranging diameter, improve the rigidity of milling cutter, milling cutter is extended service life, does not need often to change milling cutter, and can process with more speed, improve working (machining) efficiency.
2. be provided with cooling liquid flowing channel, can coolant be saved, improve cooling effect, extend cutter head service life.
3. described in, the spiral angle of cutter head has at least two kinds of angles of inclination, and the spiral angle of milling cutter bottom is greater than the spiral angle on milling cutter top, can reach structure tough and facilitate the effect of chip removal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figure 1, a kind of milling cutter, comprise handle of a knife and cutter head, described handle of a knife 1 is connected by optical axis 3 with between cutter head 2, and the diameter of optical axis 3 is less than the diameter of cutter head 2, the length of optical axis 3 is greater than the length of cutter head 2, and handle of a knife 1, optical axis 3 and cutter head 2 offer mutually through cooling liquid flowing channel 4 along axis.
The spiral angle of described cutter head 2 has at least two kinds of angles of inclination, and the spiral angle of milling cutter bottom is greater than the spiral angle on milling cutter top.
Described handle of a knife 1 surface offers annular groove 5, can improve the fixing intensity of milling cutter.
The utility model is less than the optical axis 3 of cutter head 2 by arranging diameter, improve the rigidity of milling cutter, milling cutter is extended service life, does not need often to change milling cutter, and can process with more speed, improve working (machining) efficiency.By arranging cooling liquid flowing channel 4, cooling fluid can flow into cutter head 2 from cooling liquid flowing channel 4 quantitatively, and coolant is few, and good cooling results, extend the service life of cutter head 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
