Description
Technical field
The utility model belongs to process tool technical field, particularly relates to the polygon location structure of a kind of grooving cutter.
Background technology
The locate mode of existing grooving cutter blade is top locating surface, lower locating surface and rear end location face location directly.Each locating surface is all narrow, especially rear end locating surface.But the processing of each locating surface can not accomplish it is face contact completely, thus it is little that each locating surface is contacted, and locates insecure.In cutter grooving process, blade is stressed to shrink back, and causes locating surface easy conquassation in rear end even to forge a knife, shortens cutter life.
Utility model content
Technical problem to be solved in the utility model is to provide the polygon location structure of grooving cutter that a kind of locating effect is better, cutter life is longer.
The utility model solves the polygon location structure of grooving cutter that its technical problem adopts, comprise cutter hub, section groove blade and housing screw, described cutter hub there is locating slot, described locating slot comprises locating surface, lower locating surface and rear end locating surface, described section groove blade comprises the upper surface mated with described upper locating surface, the lower surface mated with described lower locating surface and the rear end face mated with described rear end locating surface, described section groove blade is fixed in described locating slot, extrude described cutter hub by described housing screw to make to fit tightly between described upper surface and described upper locating surface and between described lower surface and described lower locating surface, rear end locating surface on described cutter hub comprises the straight locating surface of planar shaped and the circular arc locating surface of arc, described straight locating surface and described circular arc locating surface arc transition.
Further, the radius of described circular arc locating surface is 10 to 20 degree.
The beneficial effects of the utility model are: the rear end locating surface due to the locating slot of cutter hub adopts the multiaspect location structure of straight locating surface and circular arc locating surface, and the rear end locating surface form fit of the rear end face of section groove blade and cutter hub, the Dual positioning of the rear end face of section groove blade can be realized, thus add the positioning intensity of cutter hub and section groove blade, improve cutting-tool's used life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the close-up schematic view of Fig. 1;
Parts, position and numbering in figure: cutter hub 1, section groove blade 2, housing screw 3, locating slot 11, upper locating surface 111, lower locating surface 112, rear end locating surface 113, straight locating surface 1131, circular arc locating surface 1132, upper surface 21, lower surface 22, rear end face 23.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.
As depicted in figs. 1 and 2, the utility model comprises cutter hub 1, section groove blade 2 and housing screw 3, described cutter hub 1 there is locating slot 11, described locating slot 11 comprises locating surface 111, lower locating surface 112 and rear end locating surface 113, described section groove blade 2 comprises the upper surface 21 mated with described upper locating surface 111, the lower surface 22 mated with described lower locating surface 112 and the rear end face 23 mated with described rear end locating surface 113, described section groove blade 2 is fixed in described locating slot 11, extrude described cutter hub 1 by described housing screw 3 to make to fit tightly between described upper surface 21 and described upper locating surface 111 and between described lower surface 22 and described lower locating surface 112, rear end locating surface 113 on described cutter hub 1 comprises the straight locating surface 1131 of planar shaped and the circular arc locating surface 1132 of arc, described straight locating surface 1131 and described circular arc locating surface 1132 arc transition.Rear end locating surface 113 is made up of straight locating surface 1131 and circular arc locating surface 1132, on the one hand, circular arc locating surface 1132 adds contact area when section groove blade 2 is located with locating slot 11, on the other hand, rear end locating surface 113 is made up of two faces, adopt multiaspect positioning principle, the factor of these two aspects can improve cutter hub 1 and the locating effect of section groove blade 2, can extend cutting-tool's used life.In actual mechanical process, first section groove blade 2 is placed in the locating slot 11 of cutter hub 1; Then housing screw 3 is slowly tightened, in the process of tightening housing screw 3, the position of section groove blade 2 is finely tuned, the upper locating surface 111 of upper surface 21 with locating slot 11 of section groove blade 2, the lower surface 22 of section groove blade 2 and the lower locating surface 112 of locating slot 11, the rear end face 23 of section groove blade 2 are fitted completely with the rear end locating surface 113 of locating slot 11; Finally, tighten after housing screw 3 reaches the limit of position, stop tightening action.
Concrete, in order to improve further cutter hub 1 rear end locating surface 113 can with the stablizing effect of the rear end face 23 of section groove blade 2, the radius of described circular arc locating surface 1132 is 10 to 20 degree.
