Abstract
The invention relates to the field of cutter machining, in particular to a four-edge chamfering cutter. The four-edge chamfering cutter comprises a cutter bit and a cutter handle. The cutter bit is arranged at the front end of the cutter handle, and the cutter bit and the cutter handle are integrally formed. The four-edge chamfering cutter is characterized in that the cutter bit comprises four cutting edge installation parts arranged on the cutter bit, cutting edges are arranged on the outer sides of the installation parts, the cutter bit is in a taper shape, chip removal grooves are formed between the installation parts, the taper of the cutter bit is 28 degrees, the upper side face of the cutter bit is provided with vent holes communicated with the upper surface of the cutter handle, circular holes communicated with the vent holes are formed in the side surface of the cutter handle, a plurality of grooves are formed in the upper end of the cutter handle, circular-arc-shaped protrusions are arranged in the grooves, and the bottom ends of the protrusions are connected with the bottoms of the grooves through springs. The four-edge chamfering cutter is good in heat dissipating effect and clamping effect and capable of reducing resonance produced when the cutter works.
Description
Technical field
The present invention relates to a kind of tool sharpening field, particularly relate to a kind of four sword rose reamers.
Background technology
In the time of tool sharpening, usually need to use rose reamer, in the time of chamfer machining, can produce a large amount of heat, a large amount of heat can reduce the service life of cutter, improves the wearing and tearing of cutter head, is adding man-hour, between cutter and clamping device, can produce resonance, resonance can affect the machining accuracy of cutter.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of good heat dissipation effect, and clamping is effective, can have four sword rose reamers of the resonance producing while reducing except cutter work.
The technical scheme solving the problems of the technologies described above is as follows:
Four sword rose reamers, comprise cutter head and handle of a knife, cutter head is arranged on handle of a knife front end, cutter head and handle of a knife are formed in one, cutter head comprises four cutting edge installation portions that are arranged on cutter head, cutting edge is arranged on installation portion outside, cutter head is taper, between described installation portion, be provided with chip area, the tapering of described cutter head is 28 °, described cutter head upper side offers passage, passage communicates with handle of a knife upper surface, on described handle of a knife side surface, offer the circular hole communicating with passage, described handle of a knife upper end is provided with some grooves, in groove, be equipped with arc-shaped convex, bump bottom ends is connected by spring with bottom portion of groove.
Between described chip area and handle of a knife, be provided with dovetail lead-over groove.
Described chip area is provided with limit clearly.
Adopt such scheme, cutter head is taper, the tapering of cutter head is 28 °, be convenient to chamfering, described cutter head upper side offers passage, passage communicates with handle of a knife upper surface, on described handle of a knife side surface, offer the circular hole communicating with passage, in the time that working, cutter can produce a large amount of heat, heat on cutter head can distribute by the passage on cutter head, improve the service life of rose reamer, reduce due to overheated produced wearing and tearing, handle of a knife upper end is provided with groove, groove kind is provided with arc-shaped convex, bump bottom ends is connected by spring with bottom portion of groove, in the time that rose reamer is worked, in the time clamping rose reamer, projection can hold out against clamping device under the effect of spring, prevent owing to filling the problems such as not clamping, make rose reamer in the time of work, produce resonance, reduce the crudy of rose reamer, affect machining accuracy.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in the figure, four sword rose reamers, comprise cutter head 1 and handle of a knife 2, cutter head 1 is arranged on handle of a knife 2 front ends, cutter head 1 and handle of a knife 2 are formed in one, cutter head 1 comprises four cutting edge installation portions that are arranged on cutter head 1, cutting edge 3 is arranged on installation portion outside, cutter head 1 is taper, between installation portion, be provided with chip area 4, the tapering of cutter head 1 is 28 °, be convenient to chamfering, facilitate tool sharpening chamfering, or be processed with the hole of tapering, cutter head 1 upper side offers passage 5, passage 5 communicates with handle of a knife 2 upper surfaces, on described handle of a knife 2 side surfaces, offer the circular hole communicating with passage 5, in the time that working, cutter can produce a large amount of heat, heat on cutter head can distribute by the passage 5 on cutter head 1, improve the service life of rose reamer, reduce due to overheated produced wearing and tearing, handle of a knife 2 upper ends are provided with some grooves 6, groove 6 is equipped with arc-shaped convex 7, projection 7 bottoms are connected by spring 8 with groove 6 bottoms, in the time that rose reamer is worked, in the time clamping rose reamer, projection 7 can hold out against clamping device under the effect of spring 8, prevent owing to filling the problems such as not clamping, make rose reamer in the time of work, produce resonance, reduce the crudy of rose reamer, affect machining accuracy.
Preferably, between chip area 4 and handle of a knife, be provided with dovetail lead-over groove 2, be convenient to chip removal, prevent that smear metal from piling up in chip area kind.
Further, chip area 4 is provided with limit clearly, is convenient to chip removal, ensures machined surface surface smoothness.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
