The utility model relates to a diamond roller for grinding hobbing cutters, which comprises a roller body, wherein at least one side edge of the outer circumference of the roller body is embedded with a circle of CVD diamond particles, and the embedding direction of each CVD diamond particle forms an included angle of 45 degrees with the central line of the roller body; the exposed part of the CVD diamond particles is in a diamond shape, namely the two surfaces of the CVD diamond particles exposed on the outer circumference and the side part of the roller body are in a triangle shape; according to the CVD diamond mosaic structure, when the diamond roller grinds the grinding wheel, the diamond-shaped corner in the CVD exposed surface is always contacted with the grinding wheel, and two triangular surfaces adjacent to the corner can play a role in removing the grinding and can enable the diamond-shaped using and correcting corner to be always in a self-sharpening state along with the abrasion of the diamond-shaped triangular surface; therefore, the abrasion resistance of the grinding wheel dressed by the roller can be met, and the roller can realize the shape correction processing of random modulus tools at any time, so that the service life of the diamond roller for hob grinding is prolonged by 4-5 times.
Description
Technical Field
The utility model relates to a gear hobbing cutter is diamond gyro wheel for grinding belongs to diamond gyro wheel technical field.
Background
The diamond roller is a grinding wheel dresser, and is a special tool for copying the special shape of the roller to the surface of a grinding wheel for grinding precision parts; the machining and grinding of hobbing tools in the tool industry are carried out by grinding a grinding wheel into a special shape through a diamond roller by a CNC (computerized numerical control) program of a machine tool and then grinding the machined tool through the special shape of the ground grinding wheel.
In the prior art, when a straight-strip inlaid CVD diamond is used for grinding a grinding wheel, after a tool is machined from a small module to a large module along with the grinding of the diamond shape in an initial state, a roller is almost worn to be incapable of grinding a complete tooth shape; therefore, the service life of the combined roller is basically only about 3 months.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a diamond roller for grinding hobbing cutter in order to overcome the defects of the prior art.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a diamond roller for grinding a hobbing cutter comprises a roller body, wherein a circle of CVD diamond particles is inlaid in at least one edge of the outer circumference of the roller body, and the inlaying direction of each CVD diamond particle forms an included angle of 45 degrees with the central line of the roller body; the exposed part of the CVD diamond particles is in a diamond shape, namely the two surfaces of the CVD diamond particles exposed on the outer circumference and the side part of the roller body are in a triangle shape.
Preferably, two surfaces of the CVD diamond particles exposed on the outer circumference and the side part of the roller body are isosceles right triangles, and the right angle is the opposite angle of the grinding edge of the CVD diamond particles.
Preferably, there is a space between adjacent CVD diamond particles, the space forming a cutting space.
Preferably, two circles of CVD diamond particles are inlaid on two side edges of the outer circumference of the roller body respectively, and the two circles of CVD diamond particles are symmetrical to each other.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the scheme breaks through the conventional CVD diamond mosaic structure, the diamond is inlaid by rotating an angle of 45 degrees when the CVD straight strips are arranged, and the diamond exposed surface rotating the angle of 45 degrees is ground into a diamond shape when the later-stage precision finishing is carried out; thus, when the diamond roller grinds the grinding wheel, the mosaic structure is always contacted with one diamond-shaped corner in the CVD exposed surface, and two triangular surfaces adjacent to the corner can play a role in removing the grinding and can enable the diamond-shaped using and correcting corner to be always in a self-sharpening state along with the abrasion of the diamond-shaped using and correcting corner; therefore, the abrasion resistance of the grinding wheel dressed by the roller can be met, and the roller can realize the shape correction processing of random modulus tools at any time, so that the service life of the diamond roller for hob grinding is prolonged by 4-5 times.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
FIG. 1 is a schematic view of a part of a diamond roller for grinding a hobbing cutter according to the present invention;
FIG. 2 is a schematic view of a cross-sectional structure of a diamond roller for grinding a hobbing cutter according to the present invention;
figure 3 is the utility model discloses a side local structure schematic diagram of gear hobbing cutter diamond roller for grinding.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figures 1-3, a gear hobbing cutter diamond roller for grinding, contain gyro wheel body 1, the both sides edge of the outer circumference of gyro wheel body 1 respectively inlays and has round CVD diamond particle 2, two rings of CVD diamond particle 2 mutual symmetries, leaves the interval between the adjacent CVD diamond particle 2, this interval forms cutting space 3.
The inlaying direction of each CVD diamond particle 2 forms an included angle of 45 degrees with the central line of the roller body 1; the exposed part of the CVD diamond particles 2 is in a diamond shape, namely two surfaces of the CVD diamond particles 2 exposed on the outer circumference and the side part of the roller body 1 are in isosceles right triangle shapes, and the right angle is the opposite angle of the grinding edge of the CVD diamond particles 2.
According to the scheme, the angle of 45 degrees is selected when the roller body 1 is inlaid with the CVD diamond, then the exposed surface of the CVD diamond is ground into the diamond-shaped CVD diamond layer during precision dressing, so that the R part of the CVD diamond layer part is always in contact with the grinding wheel when the diamond roller grinds the grinding wheel, and the arrangement and cutting space 3 is designed at the CVD diamond layer part, so that the R angle of the CVD diamond layer 2 part is always in a self-sharpening state, the abrasion resistance of the grinding wheel dressed by the roller can be met, and the roller can realize the dressing processing of a random modulus cutter at any time.
The product of this scheme is verified through trying at domestic many hobbing cutter processing producers and hobbing cutter lathe producers, and the diamond gyro wheel of this technology preparation has not only solved the technological blank that the superhard grinding wheel was maintained to the hobbing cutter trade, has prolonged the wearability of gyro wheel when maintaining ordinary grinding wheel more, and the diamond gyro wheel can both realize random modulus cutter's general processing at any time moreover.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
