Abstract
The utility model discloses a precision circular arc chamfer tool. The precision circular arc chamfer tool comprises a handle, a tool bit, a part with the largest outer diameter, a chip flute, a main cutting blade and a flank, wherein the handle is fixedly connected with the tool bit; the chip flute is located in the main cutting blade; the part with the largest outer diameter is located between the tool bit and the flank; the main cutting blade penetrates through the flank, the part with the largest outer diameter and the tool bit; the diameter of the chip flute increases from small to large and then decreases. According to the precision circular arc chamfer tool, chip removal is smooth, the service life is prolonged, and product precision is improved.
Description
Technical field
The utility model relates to a kind of rose reamer, particularly relates to a kind of accurate circular arc chamfering cutter.
Background technology
Limit, hole chamfering and right-angle side chamfering after rose reamer is processed as metal processing mesopore, development along with machinery industry, the roughness of user to limit, the hole right-angle side of rose reamer converted products, working (machining) efficiency, cutter life, all propose requirements at the higher level delivery dates etc., traditional rose reamer significant discomfort is answered Development of Machine Industry.Tradition rose reamer chip pocket adopts single linear, and front end chip space is too large, insufficient strength, and rear end chip space is too little, and bottom land is 90 degree, and right angle chip removal is not smooth, so the problem such as service life is short, and Product Precision is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of accurate circular arc chamfering cutter, and its chip removal is unobstructed, improves service life and Product Precision.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of accurate circular arc chamfering cutter, it is characterized in that, it comprises shank, cutter head, external diameter largest portion, holds and cut groove, main cutting edge, rear knife face, shank and cutter head are fixed, appearance is cut groove and is positioned at main cutting edge, external diameter largest portion is between cutter head and rear knife face, and main cutting edge is through rear knife face, external diameter largest portion and cutter head, holds the diameter of cutting groove and reduces after from small to large again.
Preferably, the angle of described rear knife face is 120 degree, and the angle of main cutting edge and horizontal plane is 12 degree, and the angle that appearance is cut groove is 60 degree.
Preferably, between described shank and cutter head, by a link, be fixed.
Preferably, the diameter of described link is less than the diameter of shank.
Positive progressive effect of the present utility model is: the accurate circular arc chamfering blade row bits of the utility model are unobstructed, improve service life and Product Precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of the accurate circular arc chamfering cutter of the utility model.
Fig. 2 holds the structural representation of cutting groove in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As depicted in figs. 1 and 2, the accurate circular arc chamfering cutter of the utility model comprises shank 1, cutter head 2, external diameter largest portion 3, holds and cut groove 4, main cutting edge 5, rear knife face 6, shank 1 and cutter head 2 are fixing, appearance is cut groove 4 and is positioned at main cutting edge 5, external diameter largest portion 3 is between cutter head 2 and rear knife face 6, main cutting edge 5 is through rear knife face 6, external diameter largest portion 3 and cutter head 2, holds the diameter of cutting groove 4 and reduces after from small to large again.Between shank 1 and cutter head 2, can be fixed by a link 7, be convenient for changing like this.The diameter of link 7 is less than the diameter of shank 1, increases like this bonding strength.
The angle A of rear knife face 6 is 120 degree, and main cutting edge 5 is 12 degree with the angle of horizontal plane, and the angle C that appearance is cut groove 4 is 60 degree, and such structure is the most reasonable, and intensity is maximum.
Hold the diameter cut groove 4 and reduce after from small to large again, guarantee that like this each cross section chip space is quite reasonable, cutter intensity is improved like this, and chip removal is also very smooth and easy, improves service life and Product Precision, reduction product cost.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
