Abstract
The utility model discloses a step type precise surface milling cutter with fine teeth and capable of turning position, totally adopting double-faced countersunk head hole eight-edge fine cutter blades capable of turning position. The arrangement method is that one group of blades has two blades symmetrically arranged, and two groups of blades are successively arranged in step type. Two to three grades of step finishing surface are formed in primary advance of tool, so the surface process quality index is effectively improved. The utility model has the advantages of reasonable design, simple structure, good manufacturability, rapidity and convenience, high reliability, high positioning precision and high utilizing rate of the blade material.
Description
The utility model is used for the finish-milling processing on the big plane of machine components (as automobile, tractor cylinder body etc.).
Domestic big plane finish-milling generally adopts sharpening finish-milling cutter in the welded type body, or adds 1～2 precise cutter on the indexable face milling cutter at present, and there is subject matter in it; The cutter structure complexity, manufacture difficulty is big, and smart increment is jumped low precision, machined surface quality instability.Through consulting the smart face milling cutters data of external relevant cutter professional production factory; A kind of milling cutter all adopts precise cutter (being wiper insert), and its cutting edge is on same cutting plane; Another kind of milling cutter adopts and rough mills blade (most tooth), adds precise cutter (1～2 tooth), respectively on same cutting plane.These two kinds of finish-milling cuttves all belong to the one-level ladder finish-milling surface in one-pass, thereby are difficult to the stable predetermined suface processing quality requirement that reaches.
The purpose of this utility model is to provide the smart tooth of a kind of staged indexable smart face milling cutters, and this smart face milling cutters are not only simple in structure, economy, and the stock-removing efficiency height, and can stablize the surface quality requirement that reaches the processing of big plane.
The feature that the utlity model has is: in smart face milling cutters, all adopt the indexable precise cutter of two-sided counter sink eight swords.The method of its blades aligned: per two blades are to being called one group, and staged is arranged in pairs successively.In one-pass, form 2～3 grades of ladder finish-milling finished surfaces (the minor diameter milling cutter is two ladders, and the major diameter milling cutter is three ladders).The finish-milling of each ladder has all been established better finished surface basis for the next stage ladder, reaches the requirement of afterbody stepped surfaces crudy thereby effectively stablize.
Below in conjunction with accompanying drawing smart face milling cutters of the present utility model are described further: Fig. 1 is a front view of the present utility model, illustrates that smart face milling cutters are by cutter hub 1, locating shaft 2, and countersunk head holding screw 3, precise cutter 4, these four bare bones are formed.Fig. 2 is the side view of this Fig. 1, and the position of cutter hub 1 and precise cutter 4 is described.Fig. 3 is the partial sectional view along N-N line among Fig. 1, and locating shaft 2, the position of precise cutter 4 in cutter hub 1 are described.Fig. 4 is the partial sectional view along M-M line among Fig. 1, illustrates that countersunk head holding screw 3 clamps the position of precise cutter 4 in cutter hub 1.Fig. 5 is the partial schematic diagram of Fig. 1 cutter tooth, when cutter hub 1 rotation is described, and the lap position of precise cutter 4.Fig. 6 is the vertical view of Fig. 5 cutter tooth, when cutter hub 1 rotation is described, and the staged arrangement position that precise cutter 4 is overlapping.Numeral in Fig. 1 square frame is the prefix mark of beating on cutter hub 1, and Fig. 5, Fig. 6 are the expression precise cutter 4 ladder order and the positions of arranging in pairs successively.
The structure of the smart face milling cutters of the utility model: precise cutter 4 places the cutter groove right angle face of cutter hub 1 big cutting edge inclination to be close to and makes axial location, and is close to locating shaft 2 and does radial location.The aligning method of precise cutter 4 is the requirements according to the utility model feature, and locus in cutter hub 1 cutter groove and dimensional accuracy guarantee.
The characteristics that the utility model has are: 1. simple in structure, reasonable in design. 2. the smart tooth row row of staged are conducive to improve suface processing quality. 3. two-sided counter sink eight sword turnable finish-milling blades, the stock utilization height, transposition is convenient, reliable clamping. 4. anufacturability is good, and cost is low, suitable batch production.
Claims (2)
1, the indexable smart face milling cutters of the smart tooth of staged is characterized in that all adopting precise cutter, aligning method be per two blades to being called one group, staged is arranged in pairs successively.In one-pass, form 2～3 grades of ladder polished surfaces, thus the effectively stable afterbody stepped surfaces crudy that reaches.
2, smart face milling cutters as claimed in claim 1 is characterized in that precise cutter is the indexable formulas of two-sided counter sink eight swords.
