Description
Technical field
The utility model relates to a kind of cutter apparatus field, particularly relates to a kind of two sword rose reamers.
Background technology
When tool sharpening, usually need to use rose reamer, can produce a large amount of heat and burr when chamfer machining, a large amount of heat can reduce cutting-tool's used life, improve the wearing and tearing of cutter head, and the fineness of burr to finished surface also exists adverse influence.
Summary of the invention
The utility model, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of good heat dissipation effect, can remove two sword rose reamers of burr.
The technical scheme solved the problems of the technologies described above is as follows:
Two sword rose reamers, comprise cutter head and handle of a knife, cutter head is arranged on handle of a knife leading portion, cutter head and handle of a knife are formed in one, cutter head comprises two the cutting edge installation portions be arranged on cutter head, cutting edge is arranged on outside installation portion, cutter head is taper, chip area is provided with between described installation portion, the tapering of described cutter head is 28 °, described cutter head upper side offers passage, passage communicates with handle of a knife upper surface, described handle of a knife side surface offers some circular holes communicated with passage, cavity is provided with in the middle part of handle of a knife, cavity side offers opening, opening part is provided with arc-shaped convex, handle of a knife inside is arranged on inside arc-shaped convex, described arc-shaped convex inner side edge is connected by the inner surface of spring with handle of a knife inner chamber, described arc-shaped convex is provided with cutting edge.
Dovetail lead-over groove is provided with between described chip area and handle of a knife.
Described chip area is provided with limit clearly.
Adopt such scheme, cutter head is taper, the tapering of cutter head is 28 °, facilitate chamfering, or be processed with the hole of tapering, cutter head upper side offers passage, passage communicates with handle of a knife upper surface, described handle of a knife side surface offers some circular holes communicated with passage, a large amount of heat can be produced when cutter works, heat on cutter head can be distributed by the passage on cutter head, improve the service life of rose reamer, reduce due to overheated produced wearing and tearing, cavity is provided with in the middle part of handle of a knife, cavity side offers opening, opening part is provided with arc-shaped convex, handle of a knife inside is arranged on inside arc-shaped convex, arc-shaped convex inner side edge is connected by the inner surface of spring with handle of a knife inner chamber, arc-shaped convex is provided with cutting edge, rose reamer is moved downward, arc-shaped convex is made to encounter machined surface upper surface, when cutter continues down to move, by the effect of downward force, make arc-shaped convex to handle of a knife internal motion, by the cutting edge on circular arc and circular arc, burr on machined surface upper surface is removed, when arc cam is when workpiece machining surface is inner, by the top of arc cam by the burr removing of machined surface inside, when arc cam is through work pieces process lower surface, arc-shaped convex is outwards moved under the action of the spring, burr below machined surface is also removed totally.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in the figure, two sword rose reamers, comprise cutter head 1 and handle of a knife 2, cutter head 1 is arranged on handle of a knife 2 leading portion, cutter head 1 and handle of a knife 2 are formed in one, cutter head 1 comprises two cutting edge 3 installation portions be arranged on cutter head 1, cutting edge 3 is arranged on outside installation portion, cutter head 1 is taper, chip area 4 is provided with between installation portion, the tapering of described cutter head 1 is 28 °, cutter head 1 upper side offers passage 5, passage 5 communicates with handle of a knife 2 upper surface, described handle of a knife 2 side surface offers some circular holes 6 communicated with passage 5, a large amount of heat can be produced when cutter works, heat on cutter head 1 can be distributed by the passage 5 on cutter head 1, improve the service life of rose reamer, reduce due to overheated produced wearing and tearing, cavity is provided with in the middle part of handle of a knife, cavity side offers opening, opening part is provided with arc-shaped convex 7, handle of a knife inside is arranged on inside arc-shaped convex 7, arc-shaped convex 7 inner side edge is connected with the inner surface of handle of a knife 2 inner chamber by spring 8, arc-shaped convex 7 is provided with cutting edge, arc-shaped convex 7 comprises and is provided with the transition arc that circular arc plays 7 both sides, transition arc facilitates projection to enter work pieces process face, when rose reamer processing through hole, rose reamer is moved downward, arc-shaped convex 7 is made to encounter machined surface upper surface, when cutter continues down to move, by the effect of downward force, make arc-shaped convex 7 to handle of a knife internal motion, by the cutting edge on circular arc and circular arc, burr on machined surface upper surface is removed, when arc-shaped convex 7 is when workpiece machining surface is inner, by the top of arc-shaped convex 7 by the burr removing of machined surface inside, when arc-shaped convex 7 is through work pieces process lower surface, under the effect of spring 8, arc-shaped convex 7 is outwards moved, burr below machined surface is also removed totally.
Preferably, be provided with dovetail lead-over groove 9 between chip area 4 and handle of a knife 2, be convenient to chip removal, prevent chip from piling up in chip area kind.
Further, chip area is provided with limit 10 clearly, is convenient to chip removal, ensures machined surface surface smoothness.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
