The effective utilization rate of the grinding wheel is determined to be about 0.65 times of the diameter of a finished product (different according to different purposes), for example, a grinding wheel with 900 outer diameters and 305 aperture is taken as an example, the effective utilization part is a ring with the diameter of 900-585, and the part with the diameter of 585-305 can only be used as industrial waste, so that the waste of resources is caused.
In the prior art, when the grinding wheel is installed, the grinding wheel is firstly installed on the flange, and then the grinding wheel is installed on the spindle of the grinding machine through the flange. Because the two different shafts make the mounted grinding wheel unbalanced, the grinding wheel is easy to vibrate after being mounted on a grinding machine, and the main shaft is easy to damage during high-speed operation, so that the processing precision of a ground part is influenced, therefore, the grinding wheel mounted on the flange plate is firstly trimmed before being mounted on the grinding machine, the trimming time is usually 1-2 hours, and the time is long. Particularly, in small-lot production, the grinding wheel needs to be replaced every time one or a plurality of parts are machined, sometimes the replacement time of the grinding wheel even exceeds the working time of the grinding wheel, and therefore the working efficiency can be greatly improved if the dressing of the grinding wheel can be reduced.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a disc emery wheel of tapering location to the not enough of above prior art.
The technical proposal of the utility model for solving the technical problem is that: a taper positioning disc-shaped grinding wheel is characterized in that: the disc-shaped grinding wheel types comprise a parallel grinding wheel, a shaft end grinding wheel and a cylindrical gear molding grinding wheel; the disc-shaped grinding wheel structure comprises a grinding wheel body and a metal base body, the grinding wheel body is of an annular structure, a hole is formed in the middle of the grinding wheel body, the metal base body is of an annular structure, and the metal base body is fixed in the hole of the grinding wheel body; the middle of the metal base body is provided with a positioning hole.
The positioning hole of the metal substrate is a straight hole.
A series of bolt locking holes are arranged on the periphery of the metal matrix positioning hole.
The positioning hole of the metal base body is a tapered hole.
A series of bolt locking holes are arranged on the periphery of the metal matrix positioning hole.
The diameter of the metal base is equal to the minimum diameter of the effective utilization part of the grinding wheel.
The metal substrate is fixed to one side of the hole.
Compared with the prior art, the utility model discloses following outstanding beneficial effect has:
1. the waste of the grinding materials is reduced;
2. the phenomenon of unbalance of the grinding wheel caused by installation errors is basically eliminated, the dressing time is reduced, and the quick installation of the grinding wheel is realized;
3. the metal matrix replaces part of abrasive materials, so that the weight of the grinding wheel is reduced, and the grinding wheel is more convenient to carry and mount. After installation, a balance locking flange and a positioning sleeve are not arranged, the weight of a grinding wheel of a non-use part is saved, and the rotation load is reduced by more than 1/2.
