Abstract
The invention discloses an indexable arc threaded milling cutter, which comprises a cutter body, eight blades and screws, wherein the cutter body comprises eight cutter teeth and a cutter blade structure, the eight cutter teeth are uniformly distributed on the cutter blades in an outward-screwing manner; a through hole is formed in the middle of the cutter blade; a groove shape is formed in the surface of the through hole and is used for arranging a flat key matched with a transmission shaft; a thread hole is formed in the top of each cutter tooth and a screw is arranged in the thread hole; a blade with a hole is fixed at the top of each cutter tooth through a screw. The cutter teeth are distributed in the outward-screwing manner and the eight indexable blades are arranged on the cutter body, the blades can be conveniently adjusted, the cutter does not need to be subjected to adjustment or alignment and the economic cost can be effectively saved.
Description
Technical field:
The present invention relates to machining tool technical field, relate to a kind of indexable circular thread milling cutter in particular.
Background technology:
Ball-screw is the actuated element that precision optical machinery the most often uses, its major function converts rotary motion to linear movement, or change torque axis into axial repeated action power, have high accuracy concurrently simultaneously, invertibity and high efficiency feature, owing to having very little frictional resistance, ball-screw is widely used in various industrial equipment and precision instrument, it is lathe, automobile and other industries critical component, general producer is manual to model sharpening head, with domestic inner-rotary type cyclone milling machine processing screw flight, quality and efficiency lower, the adjustment of cutter is also inconvenient, the technology how effectively improving the screw cutter of processing ball-screw is a problem demanding prompt solution.
Summary of the invention:
Object of the present invention be exactly the tool setting that exists for existing inner-rotary type Whirlwind milling cutter not easily, problem that working (machining) efficiency is low proposes improvement project, devise indexable circular thread milling cutter, achieve time processing and be shaped, effectively improve the production efficiency of ball-screw.
Technology solution of the present invention is as follows:
A kind of indexable circular thread milling cutter, comprise cutter hub, blade and screw, cutter hub is cutter tooth evolute disk, cutter tooth number is eight, axially be distributed on cutter hub outer, screwed hole cartridge screw is opened at cutter tooth top, and blade with holes is fixed by screws in the cutter tooth top of cutter hub.
Preferred as technique scheme, the material of described blade is 42CrMo.
Preferred as technique scheme, described blade is SPHW120408 side's blade.
Preferred as technique scheme, the cutting edge of described blade is bicircular arcs profile of tooth.
Preferred as technique scheme, the height of described blade cut sword should higher than cutter tooth outer 2mm.
Preferred as technique scheme, described screw adopts M6 sunk screw, tangent with cutter tooth bottom screw.
Beneficial effect of the present invention is: cutter tooth is evolute, and cutter hub installs eight indexable insert tip, throw away tips, blade easy to adjust, without toolsetting, tool setting, has saved financial cost.
Accompanying drawing illustrates:
The following drawings is only intended to schematically illustrate the present invention and explain, not delimit the scope of the invention.Wherein:
Fig. 1 is the present invention's indexable circular thread milling cutter front view;
Fig. 2 is the present invention's indexable circular thread milling cutter left view
Fig. 3 is the workpiece tooth-shape structure schematic diagram of the indexable circular thread milling cutter of the present invention;
In figure, 1, cutter hub; 2, blade; 3, screw; 4, leading screw; 5, ball.
Detailed description of the invention:
Embodiment: by particular specific embodiment, working of an invention mode is described below, those skilled in the art can understand other advantages of the present invention and effect easily by content disclosed in the present specification.
Indexable circular thread milling cutter is made up of cutter hub 1, blade 2 and screw 3.Cutter hub 1 has cutter tooth 101 and cutterhead 102 structure, and eight cutters tooth 101 are distributed on cutterhead 102 in evolute mode, and cutter tooth 101 external diameter is
width is 20, and cutterhead 102 external diameter is
width is 40, has in the middle of cutterhead 102
through hole, there is groove moulding in through hole face for placing the flat key coordinated with power transmission shaft, and screwed hole cartridge screw 3 is opened at cutter tooth 101 top, and blade 2 with holes is fixed on cutter tooth 101 top by screw 3.
As shown in Figure 1, blade 2 is positioned at cutter tooth 101 top and processes leading screw, as the quenching degree that the material require high strength of blade 2, high tenacity are become reconciled, and 42CrMo can meet above-mentioned requirements well, 42CrMo material is without obvious temper brittleness, and after modifier treatment, having higher fatigue limit and anti-this impact capacities many, low-temperature impact toughness is good, is the material of outstanding screw cutter.
As shown in Figure 2, blade 2 is positioned at cutter tooth 101 top and processes leading screw, and what its specification adopted is SPHW120408 side's blade, and centre has
through hole be used for mounting screw 3, the blade 2 of specification of the same race is fixed on eight cutter tooth 101 tops, so can easily tool changing, tool setting, saving process time.
As shown in Figure 2, the cutting edge of blade 2 is bicircular arcs profile of tooth, as shown in Figure 3, ball 5 is placed at leading screw 4 screw thread place, leading screw 4 is processed by blade 2 and is obtained two screw thread curved surface, and vertically center line is symmetrical along ball 5 for two curved surfaces, and the radius of curved surface is consistent with the cutting edge radius of square blade, be all R4, ball 5 is 20 ° with the contact angle A corresponding to leading screw 4 contact wire.
As shown in Figure 2, blade 2 is sole component leading screw 4 being carried out to machining, and it stretches out the depth of thread that cutter tooth 101 highly determines processed leading screw, and we go for the dark screw thread curved surface of 2mm therefore the height that blade 2 stretches out cutter tooth 101 is also 2mm.
As depicted in figs. 1 and 2, blade 2 is fixed on cutter tooth 101 top for the processing to leading screw by screw 3, screw 3 specification used is M6, in order to avoid screw 3 and leading screw contact and with other cutters tooth interfere may, moulding tangent with cutter tooth 101 is formed to, namely without the length of stretching out cutter tooth 101 bottom it.
Described embodiment in order to illustrative the present invention, but not for limiting the present invention.Any those skilled in the art all without prejudice under spirit of the present invention and category, can modify to described embodiment, therefore the scope of the present invention, should listed by claim of the present invention.
