Abstract

The utility model discloses a taper cup wheel and belongs to the technical field of grinding tools. The taper cup wheel comprises a grinding wheel base body in a taper-cup shape and a grinding layer fixed on the end face of a cup opening of the grinding wheel base body. Concave-convex abutting-connecting structures which are matched in a fitting-complementation mode are arranged on the binding face of the grinding wheel base body and the grinding layer, so that the contact area of the grinding wheel base body and the grinding layer is increased, accordingly, the binding force between the grinding wheel base body and the grinding layer is increased, the grinding layer can be bound on the grinding wheel firmly, and accordingly when the taper cup wheel is used for grinding a workpiece, the grinding layer cannot fall off easily.

Description

A kind of flaring cup wheel

Technical field

The utility model relates to a kind of flaring cup wheel, belongs to grinding tool technical field.

Background technology

Flaring cup wheel is a kind of conventional abrasive grinding wheel, it comprises the grinding wheel base body of bowl-type and is cemented in the grinding layer on grinding wheel base body, the bowl end of grinding wheel base body, is provided with installing hole, grinding wheel base body has the effect of support grinding layer, grinding layer is mainly comprised of abrasive material, bonding agent, filler etc., be in grinding tool, to carry out the part of grinding, grinding layer is directly bonded on the end face of grinding wheel base body the rim of a bowl by binding agent.Notification number is that CN202010943U, name are called in the Chinese utility model patent of " bowl-shaped abrasive wheel with end surface grinding layer " and disclose a kind of flaring cup wheel, this flaring cup wheel comprises and is the grinding wheel base body of bowl-type and is arranged on the annular grinding layer on grinding wheel base body the rim of a bowl end face, in this flaring cup wheel, the contact-making surface of grinding wheel base body and grinding layer is plane, adhesion between grinding wheel base body and grinding layer is less, emery wheel is high speed rotating when grinding work piece, and grinding layer is easy to come off from grinding wheel base body.

Summary of the invention

The flaring cup wheel that provides a kind of grinding layer to be not easy to come off from grinding wheel base body is provided the purpose of this utility model.

For achieving the above object, the utility model adopts following technical scheme: a kind of flaring cup wheel, comprise and be the grinding wheel base body of bowl-type and be cemented in the grinding layer on grinding wheel base body the rim of a bowl end face, on the faying face of described grinding wheel base body and grinding layer, be respectively equipped with the convex-concave docking structure of the complementary fit of coincideing.

Described convex-concave docking structure is annular breach and the corresponding annular boss that coincide and coordinate with annular breach being arranged on grinding layer being opened on grinding wheel base body the rim of a bowl end face neighboring.

Described convex-concave docking structure is annular breach and the corresponding annular boss that coincide and coordinate with annular breach being arranged on grinding layer being opened on grinding wheel base body the rim of a bowl end face inner rim.

Described convex-concave structure is annular groove and the corresponding annular boss that coincide and coordinate with annular groove being arranged on grinding layer being opened on grinding wheel base body the rim of a bowl end face.

The disc structure of atresia centered by described grinding layer.

The height that defines described annular boss is a, and the total height that defines described grinding wheel base body is b, and a is less than or equal to 0.25b.

The utility model by arranging convex-concave docking structure on grinding wheel base body and grinding layer faying face, the contact area of grinding wheel base body and grinding layer is increased, thereby the adhesion between grinding wheel base body and grinding layer is increased, can make more firm being cemented on grinding wheel base body of grinding layer, therefore, the utility model is when grinding work piece, and grinding layer is not easy to come off.

Further, centered by grinding layer, the disc structure of atresia has increased the grinding area of grinding layer.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is the structural representation of the utility model embodiment 2;

Fig. 4 is the structural representation of the utility model embodiment 3.

The specific embodiment

The structure of the utility model embodiment 1 as depicted in figs. 1 and 2, flaring cup wheel in the present embodiment comprises and is the grinding wheel base body 2 of bowl-type and is cemented in the grinding layer 3 on grinding wheel base body the rim of a bowl end face, the bowl end of grinding wheel base body, is provided with installing hole 1, the disc structure of atresia centered by grinding layer 3, on the faying face of grinding wheel base body 2 and grinding layer 3, be respectively equipped with the convex-concave docking structure of the complementary fit of coincideing, the convex-concave docking structure of the present embodiment is annular breach and the corresponding annular boss that coincide and coordinate with annular breach being arranged on grinding layer being opened on grinding wheel base body the rim of a bowl end face neighboring.

The height that defines described annular boss is a, and the total height that defines described grinding wheel base body is b, in order not affect the support strength of grinding wheel base body, a≤0.25b in the present embodiment; Certainly, in the specific implementation, the value of a and b can be determined according to actual conditions.

The contact area of the present embodiment medium plain emery wheel matrix and grinding layer increases, thereby the adhesion between grinding wheel base body and grinding layer is increased, can make more firm being cemented on grinding wheel base body, therefore of grinding layer, use the flaring cup wheel of the present embodiment when grinding work piece, grinding layer is not easy to come off.

The structure of the utility model embodiment 2 as shown in Figure 3, as different from Example 1, the convex-concave structure of the present embodiment is annular breach and the corresponding annular boss that coincide and coordinate with annular breach being arranged on grinding layer being opened on grinding wheel base body the rim of a bowl end face inner rim.

As shown in Figure 4, as different from Example 1, the convex-concave structure of the present embodiment is annular groove and the corresponding annular boss that coincide and coordinate with annular groove being arranged on grinding layer being opened on grinding wheel base body the rim of a bowl end face to the structure of the utility model embodiment 3.

In other embodiment of the present utility model, convex-concave structure can be also the circular hole of even branch on grinding wheel base body the rim of a bowl end face and be arranged on identical inserting on the grinding layer cylinder in circular hole; Certainly, convex-concave structure also can be also to be arranged on the tooth slot structure on grinding wheel base body outer peripheral face and to be arranged on the tooth-shape structure of identical inserting in teeth groove on grinding layer outer peripheral face.

In other embodiment of the present utility model, the bulge-structure in convex-concave structure also can be arranged on grinding wheel base body, and corresponding, sunk structure should be arranged on grinding layer.

In other embodiment of the present utility model, grinding layer can be also cirque structure.
