Abstract
The utility model relates to a hardware machining tool, in particular to an annular bit, which comprises a cutter body, and a plurality of power-clamped blade groups on the cutter body. Each power-clamped blade group comprises two symmetrical power-clamped blades, and is respectively fixed on positions with different distances from the axis on the end surface of the cutter body; a drill chip channel is positioned in the middle of the cutter body; outer and inner blades are arranged on the power-clamped blades. The utility model has the advantages of simple structure, excellent application effect, leveled cutting, blades replacement, small drilling resistance, smooth chips removal, and excellent cooling effect for the cutter body.
Description
Technical field:
The utility model relates to a kind of five metals machining tool, especially relates to a kind of annular bit or clip type annular bit.
Background technology:
Present annular bit can not cut the periphery and the inner hole surface of processed parts usually simultaneously.In addition, the clamped cutting bit sheet is welded on the cutter hub, and the clamped cutting bit sheet will cause if any blade damage wholely to be scrapped cutter, and on the cutter hub cooling channel of chip removal is not set, has influenced raising working (machining) efficiency and service life.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, but and provides a kind of simple in structure, good layered cutting of result of use and the removable annular bit of blade.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this annular bit comprises cutter hub and four clamped cutting bit sheets, and an axial drilling cuttings passage is arranged under each clamped cutting bit sheet on the cutter hub, has a certain degree with the axle center; Four clamped cutting bit sheets are one group with two symmetrical clamped cutting bit sheets, be in respectively in the different radial positions of cutter hub end face, both two symmetry machine clip blades were arranged on outer circle place, and two symmetry machine clip blades are arranged on place, inner hole (geometry of four clamped cutting bit sheets, size are all consistent) in addition.The working range of two groups of clamped cutting bit sheets has overlapped part, when drilling each blade cut simultaneously and to institute's cutting tip be divided into periphery cutting and the cutting of inner hole surface; Convertible another unworn blade or change clamped cutting bit sheet and continue cutting when each clamped cutting bit sheet damages if any blade need not wholely be scrapped cutter because of the blade damage causes, and falls end cost; After each clamped cutting bit sheet was contained on the cutter hub, the axial line of its preceding edged surface and cutter hub formed an acute angle, and the relief angle that had of clamped cutting bit sheet itself, reduced resistance during all to drilling and chip removal plays a role.
But the utlity model has simple in structure, the good layered cutting of result of use and blade is replaceable and during drilling little, the chip removal of resistance smoothly, advantages such as cutter hub good cooling results.
Description of drawings:
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
Embodiment 1:
Referring to Fig. 1, Fig. 2, the present embodiment annular bit comprises cutter hub 5, cutter hub 5 is provided with two clamped cutting bit sheet groups, each clamped cutting bit sheet group comprises the clamped cutting bit sheet 1 of two symmetries, each clamped cutting bit sheet group is fixed on positions different apart from the axle center on cutter hub 5 end faces respectively, and both a clamped cutting bit sheet group was arranged on outer circle place, and another clamped cutting bit sheet group is arranged on place, inner hole, the working range of two clamped cutting bit sheet groups has overlapped part, is provided with drilling cuttings passage 2 in the middle of the cutter hub 5.
The clamped cutting bit sheet 1 of present embodiment can be provided with outer blade 3 and interior blade 4, be the annular cutting during 1 boring of clamped cutting bit sheet, central core is not cut, so that the efficient when improving boring, drilling cuttings passage 2 is set in the middle of cutter hub 5 handle end is used for into water, cooling in can carrying out is fully carried out cooling effect from the outside and will be got well much than general.Clamped cutting bit sheet 1 and angle normal direction are cutting edge inclination, and general angle is 0～10 °.The time be divided into two groups in cutting and cut, i.e. a clamped cutting bit sheet group turning part, bore portion in another clamped cutting bit sheet group cutting reduces cutting resistance, and vibration reduces.Clamped cutting bit sheet 1 adopts carbide alloy usually, and cutter hub 5 adopts structural steel or steel alloy usually.
Embodiment 2:
6 clamped cutting bit sheets 1 are housed on the cutter hub 5 in the present embodiment, three clamped cutting bit sheet groups just, other structure is with embodiment 1.In use can design more clamped cutting bit sheet 1, but must be that designing of certain rule arranged according to actual conditions.
The blade of the utility model embodiment also can be designed to several different shapes to be more conducive to cutting, and the design of drilling passage generally is dextrorotation, but also can be designed to left-handedly, and the fixed position of clamped cutting bit sheet group also can be adjusted according to actual conditions.The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
Claims (3)
1. annular bit, comprise cutter hub, it is characterized in that: cutter hub is provided with some groups of clamped cutting bit sheet groups, and each clamped cutting bit sheet group comprises the clamped cutting bit sheet of two symmetries, each clamped cutting bit sheet group is fixed on positions different apart from the axle center on the cutter hub end face respectively, is provided with the drilling cuttings passage in the middle of the cutter hub.
2. annular bit according to claim 1 is characterized in that: described clamped cutting bit sheet is provided with outer blade and interior blade.
3. annular bit according to claim 1 is characterized in that: described clamped cutting bit sheet group is more than two groups or two groups.
