Abstract
The invention relates to the technical field of mechanical tools, in particular to a circular-arc milling cutter. The circular-arc milling cutter comprises a cylindrical part which is connected with a cutter handle by a cutter bit, and cutting parts which are connected with the cylindrical part and are in an umbrella shape; the circumference of each cutting part is in a circular arc shape; a plurality of V-shaped grooves are uniformly formed in the circumference of the cutter bit; a plurality of convex ribs are formed on the cutting parts between the V-shaped grooves; blades are arranged on the end faces, which face the clockwise direction, of the convex ribs of the cutting parts; the outer edges of the blades adapt to the outer edges of the cutting parts; and cutting edges are arranged on the bottom faces and the outer side faces of the blades. By virtue of the circular-arc milling cutter, the machining precision of the circular-arc milling cutter is high and the bottom surface roughness of the circular-arc grooves is high.
Description
Technical field
The present invention relates to machinery knives technical field, particularly relate to arc cutter.
Background technology
Along with the development of mechanical field, part shape is more and more diversified; When bottom current milling being the rectangular channel of arc groove, after needing first milling rectangular channel, again after tool changing tool setting, then process the circular arc bottom rectangular channel further with rose cutter, cause production efficiency low, in the process of tool changing tool setting again, easily occur error; Further, due to spherical in shape bottom ball cutter, during milling arc groove, can not the bottom surface of Machining Arc groove, cause arc groove bottom surface roughness not high; Further, for the arc groove of umbrella, because radian is excessive, adopt rose cutter, can not machining accuracy be ensured.
Summary of the invention
The object of this invention is to provide a kind of machining accuracy high, the arc cutter that arc groove bottom surface roughness is high.
Technical scheme of the present invention is as follows:
Arc cutter, comprises handle of a knife, the cutter head that handle of a knife connects; It is characterized in that, described cutter head comprises the cylindrical portion be connected with handle of a knife, is connected and is the cutting portion of umbrella shape with cylindrical portion; Described cutting portion periphery is circular arc; Described cutter head periphery is evenly equipped with some " V " connected in star, the cutting portion be somebody's turn to do between " V " connected in star forms some ridges; Described cutting portion ridge is equipped with blade on clockwise end face, this limit, blade outer and limit, cutting portion outer suitable; Described blade bottom surface and lateral surface are cutting edge.
Described blade is fixed on cutting portion end face.
Described blade is detachably connected on cutting portion end face.
Described blade is the poly-golden diamond compact of upper strata diamond layer and lower floor's cemented carbide substrate.
The invention has the beneficial effects as follows: due to cutter head ridge being equipped with blade on clockwise end face, and limit, blade outer and limit, cutter head outer suitable, and cutter head comprises cylindrical portion and cutting portion, it blade lateral surface is cutting edge, therefore, the arc groove of rectangular channel and rectangular channel bottom surface can be processed when milling simultaneously, make its one-shot forming, avoid repeating processing, enhance productivity; Because cutting portion is umbrella shape, therefore when processing the arc groove of umbrella shape, machining accuracy is high; Owing to blade bottom surface being cutting edge, when milling, can the bottom surface of simultaneously milling arc groove.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is handle of a knife, and 2 is cylindrical portion, and 3 is cutting portion, and 4 is " V " connected in star, and 5 is ridge, and 6 is blade, and 7 is cutting edge, and 8 is diamond layer, and 9 is hard alloy layer.
Detailed description of the invention
Embodiment 1
Shown in Figure 1, arc cutter, comprises handle of a knife 1, the cutter head that handle of a knife connects; Described cutter head comprises the cylindrical portion 2 be connected with handle of a knife, is connected and is the cutting portion 3 of umbrella shape with cylindrical portion; Described cutting portion periphery is circular arc; Described cutter head periphery is evenly equipped with some " V " connected in star 4, the cutter head periphery be somebody's turn to do between " V " connected in star forms some ridges 5; Described cutter head ridge is equipped with blade 6 on clockwise end face, this limit, blade outer and limit, cutter head outer suitable; Described blade is welded on cutter head end face; Described blade bottom surface and lateral surface are cutting edge 7.
Due to cutter head ridge being equipped with blade on clockwise end face, and limit, blade outer and limit, cutter head outer suitable, and cutter head comprises cylindrical portion and cutting portion, it blade lateral surface is cutting edge, therefore, the arc groove of rectangular channel and rectangular channel bottom surface can be processed when milling simultaneously, make its one-shot forming, avoid repeating processing, enhance productivity; Because cutting portion is umbrella shape, therefore when processing the arc groove of umbrella shape, machining accuracy is high; Owing to blade bottom surface being cutting edge, when milling, can the bottom surface of simultaneously milling arc groove; After adopting welding, do not have gap between blade and cutter head end face, structural strength is high, and blade and cutter head can adopt different materials to make.
Embodiment 2
On the basis of embodiment 1, described blade is connected on cutting portion end face by screw.Removably connect owing to adopting, when turned and tipping occur blade, be convenient for changing, reduce production cost.
Embodiment 3
On the basis of embodiment 1, described blade is the poly-golden diamond compact of upper strata diamond layer 8 and lower floor's cemented carbide substrate 9.Due to the poly-golden diamond compact that described blade is upper strata diamond layer and lower floor's cemented carbide substrate, diamond hardness is large, not easy to wear, thus increases the service life of blade.
Embodiment 4
On the basis of embodiment 1, described ridge is coated with titanium nitride undercoating.Due to when milling ridge also can with absorption surface, apply anti abrasive coating, be conducive to reduce wearing and tearing, increase the service life.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
Claims (4)
1. arc cutter, comprises handle of a knife, the cutter head that handle of a knife connects; It is characterized in that, described cutter head comprises the cylindrical portion be connected with handle of a knife, is connected and is the cutting portion of umbrella shape with cylindrical portion; Described cutting portion periphery is circular arc; Described cutter head periphery is evenly equipped with some " V " connected in star, the cutting portion be somebody's turn to do between " V " connected in star forms some ridges; Described cutting portion ridge is equipped with blade on clockwise end face, this limit, blade outer and limit, cutting portion outer suitable; Described blade bottom surface and lateral surface are cutting edge.
