Abstract
The utility model discloses a high-efficiency indexing face-milling cutter which is a cutting tool. A cone cutter pad and a cutter ring with a groove are respectively connected and positioned with the two back ends of a blade, which solves that the traditional indexing face-milling cutter uses a main cutting edge to position and brings the indexing error. In addition, the blade adopts the design of a small subsidiary angle of declination. The utility model has the advantages of high precision, high durability, strong adaptability and high efficiency and is suitable for being used in the automatic machining production line.
Description
The utility model relates to the indexable milling cutter that a kind of cutting metal material is used, and particularly efficient indexable end face finish-milling cutter is a kind of cutting tool.
Along with the extensive use of machining automatic production line, the use amount of indexable tool is constantly increased, also strict more to the requirement of an index such as the machining accuracy of cutter, durability.Traditional indexable end mill(ing) cutter since blade to have adopted be the positioning clamping method of benchmark with the main cutting edge, caused after the transposition main cutting edge degree of wear of blade inconsistent and brought error for the location of other blades.The height of blade is uneven after the transposition, causes the end mill(ing) cutter end face run-out, thereby the durability of the cutting depth of cut and cutter is reduced, directly the efficient and the precision of influence processing.Especially to being used for the end mill(ing) cutter on the automation machined production line, the position error of cutter changes after this transposition, can produce bigger influence to processing.Increased the difficulty of adjusting, what influence was produced normally carries out.The defective of above prior art is that the utility model is wanted improved technical task.
Goal of the invention of the present utility model is to provide a kind of indexable end mill(ing) cutter that does not use blade main cutting edge location, makes the end mill(ing) cutter after the transposition still keep the precision of its end face, thereby improves the stock-removing efficiency and the precision of end mill(ing) cutter.The purpose of invention also is to improve to greatest extent the fine finishining ability of end mill(ing) cutter, to reach to mill the purpose of generation mill.
Figure of description 1 is a structure front view of the present utility model.Among the figure: 1 cutter hub, 2 edge bearings, 3 clamp mechanism, 4 blades, 5 cutter rings, 6 bolts.
Figure of description 2 is structural side views of the present utility model.Among the figure: 7 grooves.
Figure of description 3 is A-A profiles of the present utility model.
Figure of description 4 is B-B profiles of the present utility model.
Inventive features of the present utility model shows as the edge bearing that adopts cone (perhaps cylinder), and the back kissing of its conical surface and blade connects, and has realized the location, a side of blade; Outer surface at the cutter ring is dug the groove that connects cutter ring two sides, the main cutting edge of blade is placed among the groove, utilize tangent plane line of groove surfaces and cutter ring outer surface and the back kissing of blade to connect, realize the location of the another side of blade, traditional located existing defective with the blade main cutting edge thereby solved. Inventive features of the present utility model also shows as cutter tooth and adopts littler auxiliary angle, the to greatest extent roughness index on optimizing machining technology surface.
Following according to Figure of description, structure of the present utility model is done concrete introduction: efficient indexable end mill(ing) cutter is by cutter hub 1, edge bearing 2, clamp mechanism 3, blade 4, cutter ring 5 and bolt 6 constitute, it is characterized in that on the outer surface of cutter ring 5, having the groove 7 of a plurality of perforation cutter rings two sides, a main cutting edge of blade 4 places among the groove 7, a back of blade 4 and a tangent plane line kissing of groove surfaces and cutter ring outer surface connect, edge bearing 2 is a cone or cylindrical hard metal rod, place the bottom of cutter groove, another back kissing of its cone or cartridge outer surface and blade connects.Here the geometry that need to prove edge bearing 2 is selected problem, because for the selected square blade of the utility model, make blade keep a suitable major and minor drift angle, generally can adopt straight trough bed plate groove and cone edge bearing to cooperate, perhaps adopt the cooperation of skewed slot bed plate groove and cylinder edge bearing to constitute.Consider and simplify cutter groove processing technology, the utility model has adopted the technical scheme of cone edge bearing, clamp mechanism 3 can adopt the elasticity clamp mechanism that is made of spring, pull bar, pull bar tail end nut and voussoir, or multiple different clamp mechanism such as voussoir, screws clamp mechanism and pull bar voussoir clamp mechanism, the transposition of considering blade is convenient, and the utility model has selected the elasticity clamp mechanism to fix blade.The geometry of groove 7 cross sections on the cutter ring outer surface also is diversified, as del, trapezoidal, square or rectangle etc., adopted semicircular arc in the utility model, so not only processing technology is simple, can also make the tangent plane line of outer surface of itself and cutter ring more smooth-out, connect degree with the kiss that increases with the blade back.Consider the major and minor drift angle requirement of blade, the outer surface of cutter ring is advisable so that small tapering to be arranged.In order to reduce the ripple height on the finished surface, blade cut auxiliary angle φ
1Can be between 0 °～2 °.
The utility model compared with the prior art, it have accurate, simple in structure, the reliable clamping in location, easy to use, geometric angle rationally, be suitable for than roughing feed amount, durability height, can carry out characteristics such as thick, fine finishining.Can improve 2 times of work efficiency than general indexable end mill(ing) cutter, improve 2-3 doubly than the end mill(ing) cutter durability that has the smoothing tooth.Proof is used on the border factually, and cutting speed is≤150 meters/minute, and feed engagement can reach 0.5mm, and the cutting depth capacity can reach 6mm.The surface to be machined quality is: flatness 300mm:0.1, and surface roughness is better than 3.2, and durability per tooth stream time is more than 72 hours.
More than by Figure of description, an embodiment of the present utility model is done introduction, present embodiment is the efficient indexable end mill(ing) cutter that is used for the diameter 160mm of processing cast iron or non-ferrous metal and alloy.Cutter hub external diameter 161mm, equidistant 20 blades that distribute on the end face of cutter hub, the blade clamp mechanism is made of spring, pull bar, pull bar tail end nut and voussoir.The cutter ring outer surface be equally spaced 20 with the corresponding semicircular arc groove of blade, sectional dimension is R4 * 1.5mm.Edge bearing has adopted the cone metal bar, tapering≤1 °.The cutter ring outer surface is cone, and tapering≤1 ° is fixed together cutter ring and cutter hub by the hexagon socket head cap screw of four M6 * 25mm, and blade has adopted YG8 tungsten-cobalt alloy square blade, its tool cutting edge angle φ=89 °～90 °, auxiliary angle φ
1=0 °～1 °, transition blade drift angle φ
