Abstract
The utility model relates to a combined inner groove cutter, mainly aiming at solving problems of poor quality and low processing efficiency caused by high relative error when processing a plurality of inner holes differing in diameter. The combined inner groove cutter comprises a cutter handle and a cutter body, wherein cutter edges are sequentially distributed on the cutter body at intervals with same circumferential array, thus forming at least four cutting parts; each cutter edge includes a first inclined edge, a second inclined edge and a third inclined edge which are sequentially connected; the first inclined edge is parallel with the third inclined edge, and rear root parts thereof are fixed on the cutter body; the parts connected to the cutter bodies, form arcs through shovel backs; and the first inclined edges of the various cutting parts are kept on a same inclined line. According to the combined inner groove cutter disclosed by the utility model, by increasing quantities of the cutting parts and the edges, multiple processing holes are simultaneously processed; and so that product quality is improved, relative error is reduced and processing efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of bite, particularly a kind of combination inside groove cutter.
Background technology
Along with the development of industry, accuracy to product, machined surface roughness, working (machining) efficiency etc. require more and more higher, and in prior art, need multiple working procedure, and want frequent tool changing, especially for same processing endoporus, need to process the workpiece of the endoporus that multiple diameters are not identical, this makes crudy not high, and relative error also can be larger, and working (machining) efficiency is slow.
Utility model content
Relative error causes greatly deficiency of low quality, working (machining) efficiency is low when solving the not identical endoporus of the multiple diameters of processing, and the utility model provides a kind of combination inside groove cutter.
The technical scheme that the utility model adopts is: a kind of combination inside groove cutter, it comprises handle of a knife and cutter hub, the identical blade of interval circumferential array quantity successively on described cutter hub, form at least two cutting portions, described blade comprises the first oblique sword, the second oblique sword and the 3rd oblique sword that connect successively, the first oblique sword is parallel with the 3rd oblique sword, and be fixed on cutter hub, form circular arc with the coupling part of cutter hub through back-off, between the first oblique sword and the 3rd oblique sword, be provided with the second oblique sword, the oblique sword of described each cutting portion first remains on same oblique line L.
Described array blade is at least 4.
Described cutting portion adopts left-handed left sword.
There is a helical angle in the relative central shaft of the described first oblique sword.
Described helical angle angular range is 8 °-10 °.
Described blade and cutter hub are integral type structure.
The beneficial effects of the utility model are: this combination inside groove cutter has increased the quantity of cutting portion and blade, especially for same processing endoporus, can first process the endoporus that diameter is little, then need to it be reprocessed according to the size of space on the endoporus having processed, process the endoporus that multiple diameters are larger, in process, multiple cutting portions are worked simultaneously, the interior hole dimension that guarantee processes is identical, so reduce to a great extent the error between aperture, when improving the quality of products, improve working (machining) efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of combination inside groove cutter, it comprises handle of a knife 1 and cutter hub 2, 4 blades of interval circumferential array successively on described cutter hub 2, form the first cutting portion 3, the second cutting portion 4, the 3rd cutting portion 5 and the 4th cutting portion 6, described each cutting portion all adopts left-handed left sword, described blade comprises the first oblique sword 31 connecting successively, the second oblique sword 32 and the 3rd oblique sword 33, the first oblique sword 31 is parallel with the 3rd oblique sword 33, and be fixed on cutter hub 2, form circular arc with the coupling part of cutter hub 2 through back-off, due to blade and cutter hub 2 integral structures, round and smooth fixing point, can reduce the huge friction producing when inside groove cutter runs up on machining hole, improve the service life of combination inside groove cutter, between the first oblique sword 31 and the 3rd oblique sword 33, be provided with the second oblique sword 32, the oblique sword 31 of described each cutting portion first remains on same oblique line L, the path that the second cutting portion 4 can be processed along the first cutting portion 3 enters machining hole, ensure that combination inside groove cutter there will not be the phenomenon breaking in machining hole, 4 cutting portions, 4 blades on each cutting portion, proper alignment according to certain rules, ensure machining hole dimensionally stable, improve working (machining) efficiency and quality.
Inside groove as shown in Figure 4, formed by 2 kinds of different-diameter endoporus, with this combination inside groove cutter, can first process the endoporus that diameter is little, then need to it be reprocessed according to the size of space on the endoporus having processed, process the endoporus that multiple diameters are larger, in process, 4 cutting portions are worked simultaneously, the interior hole dimension processing is identical, so reduce to a great extent the error between aperture, when improving the quality of products, improved working (machining) efficiency.
On cutting portion and cutter hub 2, the quantity of the blade of circumferential array can change to optimal number according to actual processing.
There is a pitch angle alpha will in the relative central shaft of the described first oblique sword 31, gets 8 ° to 10 °, as cutting angle, make easy to process, laborsaving, according to the difference of actual machining hole and material, helical angle choose angle difference, in the present embodiment, be preferably 8 °.
Below described embodiment is only preferred embodiment of the present utility model by reference to the accompanying drawings, and the not restriction to protection domain of the present utility model, any improvement of doing based on the utility model spirit all ought to be within the utility model protection domain.
