Abstract
The utility model discloses a numerical control indexable milling cutter for spiral bevel gears, which solves the problems of low processing hardness, narrow processing range and great errors. A blade 5 is embedded into a V-shaped groove of a cutter tooth 1, the blade 5 is tightly pressed and accurately positioned in the V-shaped groove through a taper screw 4, a pressure plate 2 presses the blade 5 onto the cutter tooth 1, and the pressure plate 2 is fixed onto the cutter tooth 1 through a connecting screw 3. The cutter tooth 1 of the milling cutter is small in structural size and fine in rigidity, the tooth cutters 1 are exchangeable, large end face contact guarantees high precision, the blade 5 and the cutter tooth 1 being damaged can be replaced on demand, and four angles of the blade 5 are available, thereby increasing utilization rate of the blade 5 and reducing machining cost.
Description
[technical field]
The utility model relates to a kind of milling cutter, particularly relates to a kind of numerically-controlled invertible spiral bevel gear cutter.
[background technology]
Curved tooth awl tooth milling cutter is with the gear teeth of milling cutter as the spade wheel when adding work gear, milling cutter cutting movement track is regarded the spade face as, utilize the conjugate movement of processed gear and shovel type wheel, form the flank of tooth of processed gear by the spade face, the awl sector tooth milling cutter of Shi Yonging was to be made by high-speed steel in the past, the not wear-resisting workhardness of high-speed steel cutter is low, and the range of work is narrow, and the quenching gear can not be processed.Another kind is a high-speed steel cutter tooth cutting edge welding carbide chip, and the welding carbide-tipped milling cutter can be processed the quenching gear, and power is low easily to burst the blade processed complex but be welded into.
CN201198056Y China, on February 25th, 2009 disclosed replaceable bevel gear curved tooth milling cutter, adopt the cuboid top that the tool rest that the built-in dovetail groove in inclined-plane and inclined-plane constitutes is set, tool rest is provided with the bottom for protruding dovetail, one end is provided with the triangle cutter tooth of cutter groove, and fixed blade is realized on cutter tooth.Dovetail groove connects the location and is forbidden error big, and rigidity is not good, and rigging error is big.Dovetail groove connects the processing difficulties complexity, increases processing cost, wastes big, uneconomical.
[utility model content]
Task of the present utility model is, provides a kind of spiral bevel gear cutter range of work wide, and the cutter tooth overall structure is made, the installation accuracy height, and easily assurance, and cutter tooth integral body processes good rigidly, and blade is not fragile.The technical solution of the utility model is that blade is embedded on the cutter tooth body in the V-shaped groove, and blade is by a tapering screw in compression blade accurate location in V-shaped groove, and on the cutter tooth body, pressing plate is by being bolted on the cutter tooth body with blade pressing for pressing plate.Blade is a rhombus, and the centre is provided with the hole, uses 4 angles, is indexable insert tip, throw away tip, and blade material adopts carbide alloy, pottery, cubic boron nitride, diamond.On the cutter tooth body installing hole is set, can be straight or oblique 10 ° the cutter tooth body is installed on the cutterhead, the cutter tooth body adopts whole processing, is made by alloy steel material.
The beneficial effects of the utility model are: cutter tooth overall structure volume is small and exquisite, good rigidly, and each cutter tooth body is interchangeable, the precision height when blade and cutter tooth body have damage, can be changed as required, blade can use 4 angles, has strengthened the blade utilization rate, cuts down finished cost.The exquisite large end face rationally of this milling cutter construction contact positioning accuracy height, the repeated disassembled and assembled precision is constant, processing characteristics is reliable and stable, convenient to disassembly, efficient is high, the range of work extensively from general hardness to HRC60 ° more than the quenching gear can process, suit large area to popularize.

[specific embodiment]
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done detailed description.
Fig. 1 is a structure chart of the present utility model.Wherein 1 is the cutter tooth body, and 2 is pressing plate, and 3 is attachment screw, and 4 is the tapering screw, and 5 is blade, and 6 is locating hole.Blade 5 is embedded on the cutter tooth body 1 in the V-shaped groove, and blade 5 is pressed in the V-shaped groove precisely location by a tapering screw 4, and pressing plate 2 is pressed on blade 5 on the cutter tooth body 1, and pressing plate 2 is fixed on the cutter tooth body 1 by attachment screw 3.To the cutter hub rigidity when less demanding, remove 2,3, can adopt the front wedge to compress blade 5, reduce cutter tooth body volume.Also can fill up a slice alloy pad below the blade 5, increase cutter groove rigid protective cutter tooth body.The cutter tooth body is that whole steel alloy is made, and volume is small and exquisite, good rigidly, and each cutter tooth body is interchangeable, the precision height.Fig. 4 is the structure chart of the utility model blade, and blade 5 adopts diamond structure, and the centre is provided with the hole, use 4 angles, be indexable insert tip, throw away tip, blade material can adopt carbide alloy, pottery, cubic boron nitride, diamond, blade are not fragile, have strengthened the blade utilization rate, processing quantity is big, reduces production costs; When blade and cutter tooth have damage, can change as required.Indexable milling cutter comprises that new old model cutterhead all can use, be directly installed on the cutterhead, connecting hole can be straight or oblique 10 ° of cutterheads that can be installed in new and old type on or on the spiral forming method cutterhead, the facing cutter structure adopts helical bevel gear milling cutter body structure, dilated diameter and thickness, increase the cutterhead rigidity, also can use ready-made new and old type cutterhead, can rough mill, finish-milling, climb cutting, upmilling.Fig. 1 is outer cutter tooth body, and interior cutter tooth body is identical with Fig. 1 structure, just the blade angle difference.During use a plurality of milling cutter teeth are fixed on the cutterhead by installing hole 6, and outer cutter tooth body and interior cutter tooth body are crisscross arranged, cutting is adopted axially and radially two negative rake, increase the impact resistance of blade 5, blade is blunt can to change the angle, needn't reduce the emery wheel use amount at sharpening, improve workman's production efficiency.Fig. 2 is the structure chart of the utility model cutter tooth body 1 and blade 5.Fig. 3 is the structure chart of the utility model pressing plate 2.Fig. 5 is an attachment screw 3.Fig. 6 is a tapering screw 4.
The utility model processing is simple.
