Description
Technical field
The utility model relates to a kind of cutting-tool engineering field, particularly relates to a kind of concave arc milling cutter.
Background technology
In NC Machining Process, especially in some airplane parts digital control processings, the arc radius of some part sharp edge rounding is larger, the workload that these positions repaiied by pincers worker file is too large, quality also not easily ensures, need to adopt arc cutter digital control processing, existing arc cutter project organization is comparatively simple, the general employing Roound edge identical with part sharp edge arc radius completes digital control processing, Problems existing is that parts locally is when having micro-strain, some obvious surperficial jumps can be produced when part sharp edge processes, affect surface quality.
Summary of the invention
The utility model, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of chip removal effective, and milling fillet precision is high, the concave arc milling cutter resonating little.
The technical scheme solved the problems of the technologies described above is as follows:
Concave arc milling cutter, comprise cutter head and handle of a knife, cutter head is arranged on handle of a knife lower end, cutter head is provided with cutting edge and chip area, described cutter head is provided with some cutting edges, and be arranged on arcwall face and the chip area on each cutting edge both sides, cutting edge is at cutter head circumferentially not decile, the diameter of cutter head upper end is 17.8mm, lower end diameter is 22mm, described cutting edge is by a, b, c, d tetra-limit forms, a lower end is connected with cutter head bottom outside, upper end is connected with lower end, b limit, described a limit is one is the straight line of 3.0mm with cutter head center axle parallel length, b limit is be 3 ° of-5 ° of length with horizontal plane angle is the straight line of 1.0mm, upper end, b limit is connected with lower end, c limit, c limit is one section of radius is the circular arc of 0.93-1.0mm, upper end, c limit is connected with lower end, d limit, described d limit is one is the straight line of 3 °-5 ° with cutter head center axle clamp angle, upper end, d limit is connected with outside cutter head upper surface, arcwall face comprises arcwall face and arc lower face, upper arcwall face upper end is connected with cutter head upper surface, be connected by front cutting edge between upper arcwall face lower end with upper end, arc lower face.
Described chip area is made up of first surface and the second curved surface, and first surface is connected with the second curved surface, and the angle between first surface and the second curved surface is 30 °, and first surface another side is connected with cambered surface, and the second curved surface another side is connected with cutting edge.
Adopt such scheme, cutter head is provided with some cutting edges, cutting edge is at cutter head circumferentially not decile, make cutting edge unequal in distance each other circumferentially, Unequal distance cutting edge tooth pitch can reduce operationally the produced resonance of cutter, improve cutting-tool's used life, with the precision of processing work, arcwall face comprises arcwall face and arc lower face, upper arcwall face upper end is connected with cutter head upper surface, be connected by front cutting edge between upper arcwall face lower end with upper end, arc lower face, be provided with front cutting edge, the cutting quality of cutter can be mentioned and improve the surface quality of tool work piece machined surface.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model schematic diagram.
Detailed description of the invention
As shown in the figure, concave arc milling cutter, comprise cutter head 1 and handle of a knife 2, cutter head 1 is arranged on handle of a knife 2 lower end, cutter head 1 is provided with cutting edge 3 and chip area 4, cutter head 1 is provided with some cutting edges 3, and be arranged on arcwall face 5 and the chip area 4 on each cutting edge 3 both sides, cutting edge is at cutter head circumferentially not decile, make cutting edge circumferentially distance is each other unequal, Unequal distance cutting edge tooth pitch can reduce operationally the produced resonance of cutter, improve cutting-tool's used life, with the precision of processing work, the diameter of cutter head 1 upper end is 17.8mm, lower end diameter is 22mm, cutting edge 3 is by a, b, c, d tetra-limit forms, a lower end is connected with cutter head 1 bottom outside, upper end is connected with lower end, b limit, a limit is one is the straight line of 3.0mm with cutter head 1 central shaft parallel length, b limit is be 3 ° of-5 ° of length with horizontal plane angle is the straight line of 1.0mm, upper end, b limit is connected with lower end, c limit, c limit is one section of radius is the circular arc of 0.93-1.0mm, upper end, c limit is connected with lower end, d limit, described d limit is one is the straight line of 3 °-5 ° with cutter head 1 central shaft angle, upper end, d limit is connected with outside cutter head 1 upper surface, the cutting edge 3 of this structure, the machining accuracy of cutter when processing fillet can be improved, when preventing parts locally from having micro-strain, part sharp edge produces some obvious surperficial jumps when processing, affect surface quality, prevent milling cutter tip 1 from crumbling or to process fillet excessive, arcwall face 5 comprises arcwall face and arc lower face, upper arcwall face upper end is connected with cutter head 1 upper surface, be connected by front cutting edge 6 between upper arcwall face lower end with upper end, arc lower face, be provided with front cutting edge 6, the cutting quality of cutter can be mentioned and improve the surface quality of tool work piece machined surface.
Preferably, chip area 4 is made up of first surface and the second curved surface, first surface is connected with the second curved surface, angle between first surface and the second curved surface is 30 °, first surface another side is connected with cambered surface, and the second curved surface another side is connected with cutting edge, and chip area 4 liang of curved surface angles are more beneficial to chip removal more greatly, prevent chip from blocking chip area 4, thus affect the surface quality of machined surface.
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.
