Abstract
The utility model discloses a small-inner-diameter boring tool which comprises a toolbar and a tool bit, wherein an oblique positioning groove and a guiding groove communicated with the positioning groove are formed in the front end of the toolbar, and the tool bit is fixed in the positioning groove in the front end of the toolbar through a sunk screw. The small-inner-diameter boring tool solves the problem that according to the prior art, after the blade of a boring tool is damaged, the whole tool is discarded. The toolbar and blade of the small-inner-diameter boring tool are designed in a split mode, and the blade can be replaced after being abraded or broken. The small-inner-diameter boring tool has the advantages of being simple in structure, convenient to replace, economical, practical and the like.
Description
Technical field
The utility model relates to finding boring field, is specifically related to the interchangeable little internal diameter boring cutter of a kind of cutter head.
Background technology
Boring cutter is the one of cutting tool for boring, is generally circle handle, also has the larger workpiece user knife bar generally to see vertical car, the most frequently used occasion be exactly in hole process, reaming, profiling etc.For some findings, its hole slot to be processed is less, so little internal diameter boring cutter is widely used in finding processing, but little internal diameter boring cutter on the market has the following disadvantages at present:
1, knife bar diameter is larger, has interference with part to be processed hole.
2, cutter adopts global design, causes changing whole cutter because cutting the wearing and tearing that cause and collapsing to lack, and use cost is high.
3, point of a knife adopts spacing gradient radius, and point of a knife place easily collapses cutter.
4, chip area is more smooth, and chip removal performance is bad, easily, with the friction of processed hole, causes hole inner wall surface of poor quality.
Utility model content
For above-mentioned deficiency of the prior art, the little internal diameter boring cutter that the utility model provides has solved the problem that causes whole cutter to be scrapped after boring cutter blade damages, the knife bar of the boring cutter of this programme and blade adopt split-type design, replaceable after blade abrasion or collapse lacks, that this boring cutter has is simple in structure, be convenient to change and the advantage such as economical and practical.
In order to reach foregoing invention object, the technical solution adopted in the utility model is: a kind of little internal diameter boring cutter is provided, it comprises knife bar and cutter head, the gathering sill that described knife bar front end is provided with the locating slot of inclination and is communicated with locating slot, described cutter head is fixed in the locating slot of knife bar front end by sunk screw.
Preferably, described cutter head comprises cutter head body, one jiao of blade arranging of cutter head body and is arranged on the chip area of blade rear end.
Preferably, described blade comprises the main cutting edge, point of a knife and the wiper edges that connect as one.
Compared with boring cutter of the prior art, the beneficial effects of the utility model are:
Adopt this little internal diameter boring cutter to process, cutting resistance is little, and chip removal is smooth and easy; The little inner diameter hole processing, surface roughness is bright and clean; Point of a knife has higher intensity and good heat dispersion, and cutting adopts replaceable design with cutter head, reduces use cost, avoids because of blade wearing and tearing, collapses to lack and change whole cutter; Cutter head is fixed in the locating slot of inclination with sunk screw, has higher positioning precision.
Brief description of the drawings
Fig. 1 is the stereogram of little internal diameter boring cutter;
Fig. 2 is the stereogram of little internal diameter boring bar;
Fig. 3 is the stereogram of little internal diameter Boring head;
Fig. 4 is the enlarged drawing of A portion in Fig. 1.
Wherein, 1, knife bar; 2, locating slot; 3, gathering sill; 4, chip area; 5, main cutting edge; 6, wiper edges; 7, point of a knife; 8, cutter head.
Detailed description of the invention
As depicted in figs. 1 and 2, this little internal diameter boring cutter comprises knife bar 1 and cutter head 8, the gathering sill 3 that described knife bar 1 front end is provided with the locating slot 2 of inclination and is communicated with locating slot 2, described cutter head 8 is fixed on by sunk screw in the locating slot 2 of knife bar 1 front end, such locate mode and cutting adopt replaceable design with cutter head 8, avoid because of blade wearing and tearing, collapse to lack and cause whole boring cutter to scrap, thereby reduced production cost.
As shown in Figure 3, described cutter head 8 comprises cutter head body, one jiao of blade arranging of cutter head body and is arranged on the chip area 4 of blade rear end.Wherein, chip area 4 is made up of an inclined-plane and an arc surface.The cross section of described cutter head 8 is square.
As shown in Figure 4, described blade comprises the main cutting edge 5, point of a knife 7 and the wiper edges 6 that connect as one.Wiper edges 6 adopts shorter design, makes it have sharp cutting edge, ensures cutting " brisk ".
The front end of gathering sill 3 and chip area 4 rear ends fit together and form a channel of chip removal, have better chip removal performance, and in the time of deep hole machining finding, chip removal is smooth and easy, makes cutting resistance little, the bright and clean raising of surface roughness.
Described point of a knife 7 radiuses adopt the radial design such as space, have increased intensity and the heat dispersion of point of a knife 7, use in engineering and have reduced to collapse cutter number of times.
Although by reference to the accompanying drawings detailed description of the invention of the present utility model is described in detail, should not be construed as the restriction of the protection domain to this patent.In the described scope of claims, the various amendments that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
