Description
Technical field
The utility model relates to machining tool, is specifically related to the cross recess process tool of the key components and parts typical structure of automobile steering system.
Background technology
Power shaft is the forging part of medium carbon steel, and because forging part after the distortion and recrystallization due to metal, becomes crystal grain thinner after forging method thermal processing distortion, the axle recrystallized structure that waits of uniform size, has improved plasticity and the mechanical property of metal.In to power shaft processing cross recess process, exist tool wear fast, cross recess is overproof to the position degree of benchmark endoporus, and machined surface roughness does not reach the problem of designing requirement, causes product to scrap in a large number, and economic loss is serious.
Utility model content
The technical problem that the utility model solves is to provide a kind of cross recess process tool, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Cross recess process tool, comprises cutter hub, cutter tooth and positioning through hole, and described cutter hub is disc, and cutter hub edge is evenly distributed with described cutter tooth, and cutter hub center has described positioning through hole.
Described positioning through hole is manhole and is not with keyway.
The cutting edge profile of described cutter tooth is circular arc.
The anterior angle of described cutter tooth is 7 °, and relief angle is 5 °, and cutter hub both sides are with the angle, blade rear flank of 0.5 ° ~ 1 °, and all there is the gradient of 0.5 ° ~ 1 ° cutter hub both sides.
Described cutter hub and cutter tooth are the monolithic constructions that adopts commaterial, and its material adopts YS2T sintered-carbide tool steel.
The angle at the angle, blade rear flank of described cutter tooth is 0.5 °, and the diameter of described cutter hub is 80mm, and thickness is 6.5mm, and the diameter of described positioning through hole is 27mm, and the sheet number of described cutter tooth is 40, and the cutting edge profile arc radius of cutter tooth is 3.25mm.
Beneficial effect: the utility model cross recess process tool has the advantage of grooving cutter and R cutter concurrently, the dimensional accuracy of processing R groove is high, and surface roughness can reach Ra0.8, and cutter hub center is provided with the fixing locating hole of available bolt, realizes quick-clamping and fixes.Angle, blade rear flank is beneficial to chip removal and reduces to rub and facilitate chip removal, cutter hub, cutter tooth adopt whole YS2T sintered-carbide tool steel, reconditioning cutting edge repeatedly, cutter life is long, manufactures and to reprocess cost low, simple to operate, reliable and stable, can realize to part 100% measurement, working (machining) efficiency is high, and result of use is good.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the cross recess process tool of Fig. 1 ~ Fig. 4, comprise cutter hub 1, cutter tooth 2 and positioning through hole 3, cutter hub 1 is disc, and cutter hub 1 edge is evenly distributed with cutter tooth 2, and cutter hub 1 center has positioning through hole 3.
Positioning through hole 3 is for manhole and be not with keyway, and available bolt fixes cutter through positioning through hole 3 and realizes quick change location, adopts the bolt of M20 * 1.5 to fix in the utility model.
The cutting edge profile of cutter tooth 2 is circular arc, can process R forming surface.
The anterior angle of cutter tooth 2 is 7 °, and relief angle is 5 °, and cutter hub both sides are with the angle, blade rear flank of 0.5 ° ~ 1 °, and all there is the gradient of 0.5 ° ~ 1 ° cutter hub both sides, and angle, described blade rear flank is beneficial to chip removal and reduces friction, guarantees the surface roughness of having processed groove face.
Cutter hub 1 is the monolithic constructions that adopt commaterial with cutter tooth 2, and its material adopts YS2T sintered-carbide tool steel, the repeatedly cutting edge of reconditioning cutter tooth.Improve the actual life of cutter, reduce the purchase cost of dedicated tool.
The angle at the angle, blade rear flank of cutter tooth 2 is 0.5 °, the diameter of cutter hub 1 is 80mm, thickness is 6.5mm, the diameter of positioning through hole 3 is 27mm, the sheet number of cutter tooth 2 is 40, and the cutting edge profile arc radius of cutter tooth 2 is 3.25mm, and multiple tooth participation cutting can reduce the resistance to cutting of each tooth in working angles, extend the life-span of cross recess process tool, improve the surface roughness of machined surface.，
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
