Abstract
The utility model discloses a high-stability end mill comprising an end mill (1) provided with a cutter bar and cutter teeth, wherein each cutter tooth is provided with an end blade (2) and a circumambient blade (3); the number of the cutter teeth of the end mill (1) is even; and the end blades (2) of the cutter teeth are distributed on a same circumference unequally, namely, an included angle between the end blade (2) of each cutter tooth and every one of the end blades (2) of the two adjacent cutter teeth is different, meanwhile, a helical angle (W1) of a helical groove of the circumambient blade (3) of each cutter tooth is not equal to each helical angle (W2) of each helical grooves of every one of the circumambient blades (3) of the two adjacent cutter teeth. The high-stability end mill not only has the advantages of being good in work stability, high in work efficiency and good in processing quality, but also has the advantages of being simple in structure, easy in production and long in service life.
Description
Technical field
The utility model relates to a kind of high stable slotting cutter, belongs to the slotting cutter manufacture technology field.
Background technology
At present, in the prior art, general all the cutter tooth of slotting cutter is made into odd number tooth or even number toothing by impartial angle distribution; The slotting cutter of this odd number tooth or even number toothing by impartial angle distribution usually can take place clocklike to vibrate the appearance of this vibration when processing work; Greatly reduce the stability of slotting cutter work; Because the instability of existing slotting cutter service behaviour tends to reduce the quality of converted products, but also can reduce operating efficiency.Therefore, the result of use of existing slotting cutter still is not ideal enough.
The utility model content
The purpose of the utility model is, a kind of high stable slotting cutter is provided, stability and operating efficiency and crudy when improving slotting cutter work, thus overcome the deficiency of prior art.
The technical scheme of the utility model is to constitute like this: a kind of high stable slotting cutter of the utility model does; This high stable slotting cutter comprises the slotting cutter that is provided with knife bar and cutter tooth; And on each cutter tooth, all be provided with end sword and Zhou Ren; The quantity of the cutter tooth of its slotting cutter is even number; And the end sword of cutter tooth is not distributed on the same circumference five equilibrium, and promptly the angle of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth is inequality, and the spiral fluted helical angle of the Zhou Ren of the spiral fluted helical angle of the Zhou Ren of each cutter tooth and adjacent both sides cutter tooth is unequal simultaneously.
The quantity of the cutter tooth of slotting cutter is 4, and the end sword of 4 cutters tooth is not distributed on the same circumference five equilibrium, and promptly the angle of the angle 1 of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth and angle 2 is 93.9 ° and 86.1 ° respectively.
The quantity of the cutter tooth of slotting cutter is 4, and all sword spiral fluted helical angle W1 of per two adjacent cutters tooth of slotting cutter and the angle difference of helical angle W2 are: 1 °～10 °.
Owing to adopted technique scheme; The utility model is made into even number with the quantity of the cutter tooth of slotting cutter; And the end sword of cutter tooth is distributed on the same circumference by five equilibrium not, even the angle of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth is inequality, can make the irregular distribution of effective cutting point (promptly putting cutting force) like this; Thereby centrality, the order of disperseing cutting force; Avoid clocklike periodic cutting force vibration, improved the stability and the stationarity of Milling Process greatly, improved working (machining) efficiency and crudy.It is unequal that simultaneously the utility model makes the spiral fluted helical angle of Zhou Ren of spiral fluted helical angle and adjacent both sides cutter tooth of Zhou Ren of each cutter tooth; Thereby make the helicla flute spacing (or tooth pitch) of Zhou Ren of Zhou Ren and adjacent both sides cutter tooth of each cutter tooth unequal; The utility model adopts this helicla flute spacing inequality (or different tooth pitches) structure; Can produce an out of phase (out-phase) thus cutting movement stop the generation of resonance; Can effectively contain the vibration of cutter, improve processing fineness greatly, and increase the cutting depth and the feed speed of cutter.So, the utility model compared with prior art, the utility model not only has the good advantage of good operating stability, high efficiency and crudy, but also have simple in structure, produce easily, the advantage of long service life.
Description of drawings
Fig. 1 is the high stable slotting cutter structural representation of the utility model;
Fig. 2 is the left TV structure sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The embodiment of the utility model: the utility model is to make up according to following a kind of method that improves the slotting cutter job stability; This method is earlier by traditional technology, method and material slotting cutter; When making; The quantity of the cutter tooth of slotting cutter is made into even number, and the end sword that makes cutter tooth is distributed on the same circumference by five equilibrium not, even the angle of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth is inequality; Make the spiral fluted helical angle of Zhou Ren of spiral fluted helical angle and adjacent both sides cutter tooth of Zhou Ren of each cutter tooth unequal simultaneously, can improve the job stability of slotting cutter when processing work like this.
The structural representation of a kind of high stable slotting cutter of the utility model that makes up according to the method described above is as depicted in figs. 1 and 2; This high stable slotting cutter comprises the slotting cutter 1 that is provided with knife bar and cutter tooth; On each cutter tooth, all be manufactured with the end sword 2 and all swords 3 of conventional structure; During making; The quantity of the cutter tooth of slotting cutter 1 is made even number; And by not being distributed on the same circumference, the end sword 2 that is about to each cutter tooth is inequality with the angle of the end sword 2 of adjacent both sides cutter tooth five equilibrium with the end sword 2 of cutter tooth, and the spiral fluted helical angle W2 with all swords 3 of the spiral fluted helical angle W1 of all swords 3 of each cutter tooth and adjacent both sides cutter tooth is made into the unequal helical angle of angle (as shown in Figure 1) simultaneously.During making; Preferably the quantity with the cutter tooth of slotting cutter 1 is made into 4; Be not distributed on the same circumference end sword 2 of 4 cutters tooth five equilibrium; The end sword 2 that is about to each cutter tooth is made as 93.9 ° and 86.1 ° respectively with the angle 1 of the end sword 2 of adjacent both sides cutter tooth and the angle of angle 2, simultaneously the angle difference of the spiral fluted helical angle W1 of all swords 3 of per two adjacent cutters tooth of slotting cutter and helical angle W2 is controlled at 1 °～10 ° scope.
