Abstract
The utility model discloses a concave emery wheel of single face with metal matrix locating hole belongs to the grinding tool field, its characterized in that: the grinding wheel comprises a grinding wheel body and a metal matrix, wherein the grinding wheel body is of a cylindrical structure, a through hole is formed in the middle of the grinding wheel body, the metal matrix is of an annular structure, and the metal matrix is fixed on one side of the through hole of the grinding wheel body; the middle of the metal base body is provided with a positioning hole. Compared with the prior art have the characteristics of reducing the abrasive material waste and installing fast.
Description
Technical Field
The utility model relates to a grinding apparatus, especially a grinding wheel.
Background
Grinding wheels are a major type of grinding tool in grinding operations. One side of the single-side concave grinding wheel is provided with a recess, the outer side surface of the single-side concave grinding wheel is used for grinding the inner circle surface, and the outer end surface provided with the recess is used for grinding the inner hole and the end surface of the inner circle and the end surface of the outer circle. The working surface of the single-side concave grinding wheel is an outer circular surface and a front end surface. With the abrasion in the using process, the diameter and the thickness of the single-side concave grinding wheel are smaller and smaller, when the diameter and the thickness of the single-side concave grinding wheel are abraded to a certain size, the rest part cannot be used continuously and can only be discarded as industrial waste, and therefore the waste of resources is caused.
In the prior art, when the single-side concave grinding wheel is installed, the grinding wheel is firstly installed on the flange, and then the grinding wheel is installed on the central 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 above prior art not enough, provide a concave emery wheel of single face with metal matrix locating hole.
The technical proposal of the utility model for solving the technical problem is that: the utility model provides a concave emery wheel of single face with metal matrix locating hole which characterized in that: the grinding wheel comprises a grinding wheel body and a metal matrix, wherein the grinding wheel body is of a cylindrical structure, a through hole is formed in the middle of the grinding wheel body, the metal matrix is of an annular structure, and the metal matrix is fixed on one side of the through 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.
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.

As shown in fig. 2 and 3, the utility model discloses a grinding wheel body 1 and metal matrix 2, grinding wheel body 1 be the cylindrical structure, the centre of grinding wheel body 1 is the through-hole, metal matrix 2 fixes the one side at 1 through-hole of grinding wheel body. The middle of the metal base body 2 is provided with the positioning hole 3, the grinding material at the bottom of the groove is replaced by the metal base body 2, and the metal base body 2 can be recycled, so that the waste of resources is reduced as much as possible.
In embodiment 1, the metal substrate 2 is an annular structure, the positioning hole 3 of the metal substrate 2 is a straight hole, the size of the hole diameter is adapted to the flange, the metal substrate is mounted on the spindle of the grinding machine through the flange structure, and the mounting mode is the same as that in the prior art.
In the embodiment 2, a series of bolt locking holes 4 are arranged on the periphery of the positioning hole 3 of the metal base body 2, and the grinding wheel is fixed on the flange plate through bolts when in use. Other structures of this embodiment are the same as those of embodiment 1.
In embodiment 3, the metal base 2 is of an annular structure, the positioning hole 3 of the metal base 2 is a tapered hole, the tapered hole is adapted to a frustum at the end of a spindle of the grinding machine, the grinding wheel is mounted on the frustum of the spindle through the tapered hole, a nut is arranged at the end of the frustum, the nut is fixed on one side of the grinding wheel after being screwed down, and the other side of the grinding wheel abuts against a flange plate on the spindle. Other structures of this embodiment are the same as those of embodiment 1.
In embodiment 4, the positioning hole 3 of the metal substrate 2 is a tapered hole, and the structure thereof is the same as that of embodiment 3. The positioning holes 3 are provided at their peripheries with a series of bolt locking holes 4, which are constructed as in embodiment 2.
