Abstract
The utility model relates to a grinding wheel, which comprises a base body and a grinding layer, wherein a connecting groove with an inward notch is formed in the inner circumferential surface of the grinding layer, a connecting part inserted into the connecting groove in an anastomotic way is arranged on the outer edge of the base body, and the connecting groove and the connecting part are fixedly connected into an integral structure. The grinding wheel has the advantages that the connecting groove is formed in the grinding layer, and the connecting part is arranged on the base body, so the connecting part can be made of materials with higher structural intensity, the structural intensity of the connecting part can be ensured, and the connecting part cannot easily fracture when the grinding wheel is collided.
Description
Technical field
The utility model relates to grinding tool, relates in particular to a kind of emery wheel.
Background technology
Emery wheel is as common grinding tool, and it is widely used in daily productive life.Existing a kind of emery wheel as disclosed in Chinese patent literature CN201009169Y " mosaic type cubic boron nitride abrasive ", this emery wheel comprises matrix and grinding layer, the outer peripheral face of matrix offers bonding groove, and grinding layer is provided with the convex coordinating with bonding groove, and convex is adhesively fixed in bonding groove.Bonding groove can increase the connection area of grinding layer and matrix, thereby guarantees the bonding strength between matrix and grinding layer.The problem that existing this emery wheel exists is: convex is arranged on grinding layer, because grinding layer and convex are the overall structure being sintered together, convex must be used the material identical with grinding layer to make, grinding layer and convex itself have more crisp characteristic, when grinding layer is collided, the easily fracture and affect service life of emery wheel of this outstanding structure of convex; On the other hand, convex is arranged at the width that also makes the axial length of matrix must be greater than bonding groove and convex on grinding layer, and matrix often consists of metal or alloy, the increase of axial length has increased the weight of matrix greatly, this just causes the weight of whole emery wheel heavier, consumes energy more when reality is used.
Summary of the invention
The purpose of this utility model is to provide a kind of emery wheel, to solve the easily problem of fracture of convex in prior art.
In order to address the above problem, the technical solution of the utility model is:
A kind of emery wheel, comprises matrix and grinding layer, offers notch link slot inwardly on the inner peripheral surface of grinding layer, and the outer rim of described matrix is provided with to coincide inserts the connecting portion in described link slot, and described link slot and connecting portion are fixed into overall structure.
Described connecting portion is integrally formed on described matrix.
Described connecting portion is fixed into overall structure by bonding, welding or plating and link slot.
On the circumferencial direction perpendicular to matrix, the cross sectional shape of described link slot is rectangle, square, circular arc or taper.
On the outer peripheral face of described matrix, around being circumferentially arranged at intervals with multiple openings gap outwardly, described grinding layer comprises and described each gap multiple arc grinding blocks of corresponding setting one by one, and each arc grinding block is arranged at respectively between corresponding adjacent two gap.
The Breadth Maximum of described link slot is not less than the maximum ga(u)ge of described matrix.
The beneficial effects of the utility model are: the link slot in the utility model is opened on grinding layer, connecting portion is arranged on matrix, connecting portion can be made by the higher material of choice structure intensity like this, so just can guarantee the structural strength of connecting portion, emery wheel is when being collided, and connecting portion is easy fracture not.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is grinding layer in embodiment 2 of the present utility model and the schematic diagram that coordinates of matrix;
Fig. 4 is grinding layer in embodiment 3 of the present utility model and the schematic diagram that coordinates of matrix.
The specific embodiment
A kind of embodiment 1 of emery wheel is as shown in Figure 1: comprise matrix 3 and grinding layer, on the outer peripheral face of matrix around being circumferentially arranged at intervals with multiple openings gap 4 outwardly, grinding layer comprises and each gap multiple arc grinding blocks 1 of corresponding setting one by one, and each arc grinding block is arranged at respectively between corresponding adjacent two gap.On the inner peripheral surface of each arc grinding block, all offer notch link slot 1-1 inwardly, on the circumferencial direction perpendicular to matrix, the cross sectional shape of link slot is rectangle, the corresponding outer rim of matrix is provided with to coincide inserts the connecting portion 2 in corresponding link slot, matrix and connecting portion are one-body molded, matrix is slab structure, and the Breadth Maximum (being the width of link slot) of connecting portion is identical with the thickness of matrix, link slot with corresponding connection parts by being adhesively fixed into overall structure.
Connecting portion is arranged on matrix, just the width of connecting portion and the thickness of matrix can be accomplished to the same size, thereby greatly reduce the weight of matrix and whole emery wheel, reduced emery wheel power consumption in use.
In other embodiment of this emery wheel: each gap can also not established, now grinding layer can consist of the grinding block of an annular entirety; Connecting portion can also be wholely set by other techniques such as welding, sintering and matrix, and connecting portion also can be fixed on matrix by other syndetons such as bolts certainly; The width of connecting portion can also be greater than or less than the thickness of matrix; The shape of link slot can also be square; Connecting portion can also be by welding or plating and link slot are fixed into overall structure.
A kind of embodiment 2 of emery wheel is as shown in Figure 3: as different from Example 1, link slot 1-1 is shaped as circular arc to embodiment 2.
A kind of embodiment 3 of emery wheel is as shown in Figure 4: embodiment 3 as different from Example 1, the shape of link slot 1-1 and taper.
Claims (6)
