Abstract
The invention relates to the technical field of grinding wheels, in particular to a spherical grinding wheel. The spherical grinding wheel comprises a grinding wheel main body and a grinding layer which are fixedly arranged, wherein the grinding wheel main body comprises a concave spherical surface; the shape of the grinding layer is matched with that of the concave spherical surface; the ratio of the height H to the radius R of the concave spherical surface is not larger than 1. The spherical grinding wheel has the advantages that as the grinding wheel main body comprises the concave spherical surface and the grinding layer is arranged in the concave spherical surface, a spherical workpiece can be perfectly grinded; the grinding precision and the rate of finished products are high.
Description
Technical field
The present invention relates to abrasive grinding wheel technical field, especially a kind of sphere emery wheel.
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.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the emery wheel that existing emery wheel is all generally plane, cylinder or conical surface shape, when carrying out sanding operation to spherical metal or non-metal workpiece, polishing precision is difficult to grasp, and defect rate is high, add polishing cost, reduce the problem of operating efficiency, the invention provides a kind of sphere emery wheel, emery wheel main body 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 technical solution adopted for the present invention to solve the technical problems is: a kind of sphere emery wheel, comprise the emery wheel main body and frosted layer that are fixedly installed, 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 invention has the beneficial effects as follows: a kind of sphere emery wheel provided by the invention, emery wheel main body has a concave spherical surface, has frosted layer in concave spherical surface, perfectly can polish to spherical work-piece, polishing precision is high, and yield rate is high, effectively can reduce production cost, increase work efficiency.
