Description
Technical field
The utility model relates to abrasive grinding wheel technical field, especially a kind of sphere emery wheel electric mill.
Background technology
Emery wheel abrasive material and adhesive mixing through pressed compact, drying, roasting and making, the grinding tool of the loose various shape such as plate-like, colyliform.There are the circular bonded abrasive tool of through hole in the central authorities that emery wheel abrasive material and adhesive resin etc. are made.Emery wheel is the one that in grinding tool, consumption is maximum, applicable surface is the widest, High Rotation Speed during use, can roughly grind, half fine grinding and fluting and cut-out etc. to the cylindrical of metal or non-metal workpiece, inner circle, plane and various profiles etc.Grinding wheel structure is generally made up of working lining and matrix two parts.Working lining is made up of abrasive material, bonding agent and filler, is the working portion of emery wheel.Matrix, for accepting grinding layer, and is clamped on grinding machine spindle with ring flange in use securely, and generally meeting aluminium alloy, bakelite make matrix, and matrix also can be processed by aluminium, steel or bakelite, plays supporting working lining and the grinding tool that is installed.The quality of abrasive wheel forming quality and the height of service precision all have much relations with matrix.
In prior art, emery wheel is all generally the emery wheel of plane, cylinder or conical surface shape, and when carrying out sanding operation to spherical metal or non-metal workpiece, polishing precision is difficult to grasp, and defect rate is high, adds polishing cost, reduces operating efficiency.
Utility model content
The technical problems to be solved in the utility model is: in order to the emery wheel solving existing electric mill is all generally the emery wheel of plane, cylinder or conical surface shape, when carrying out sanding operation to spherical metal or non-metal workpiece, polishing precision is difficult to grasp, defect rate is high, add polishing cost, reduce the problem of operating efficiency, the utility model provides a kind of sphere emery wheel electric mill, the emery wheel main body of electric grinder has a concave spherical surface, in concave spherical surface, there is frosted layer, perfectly can polish to spherical work-piece, polishing precision is high, and yield rate is high.
The utility model solves the technical scheme that its technical problem adopts: a kind of sphere emery wheel electric mill, comprise electric mill and be fixedly installed on the electric grinder on electric mill output shaft, electric grinder comprises emery wheel main body and frosted layer, described emery wheel main body has a concave spherical surface, the shape of described frosted layer and concave spherical surface mating shapes, the ratio of the height H of described concave spherical surface and the radius R of concave spherical surface is not more than 1.
In order to improve the operability of sphere emery wheel, the ratio of the height H of described concave spherical surface and the radius R of concave spherical surface is 0.5.
For the ease of installing emery wheel, described emery wheel main body axle center place is provided with the installing hole being convenient to install emery wheel.
For the ease of institute's concave spherical surface of frosted layer and emery wheel main body is fitted, state frosted layer and be spliced by some fan-shaped abrasive segments.
As preferably, described frosted layer is spliced by 8 fan-shaped abrasive segments.
The beneficial effects of the utility model are: a kind of sphere emery wheel electric mill that the utility model provides, the emery wheel main body of electric grinder has a concave spherical surface, in concave spherical surface, there is frosted layer, perfectly can polish to spherical work-piece, polishing precision is high, yield rate is high, effectively can reduce production cost, increase work efficiency.
