Description

Grinding wheel for segment difference

Technical Field

The utility model belongs to the emery wheel field, concretely relates to poor emery wheel of using of section.

Background

The grinding wheel is a bonded grinding tool which is formed by bonding a common grinding material into a certain shape (mostly circular, with a through hole in the center) by a bonding agent and has certain strength. It is generally composed of abrasive, bond and air holes, which are often referred to as the three elements of a bonded abrasive tool. According to different classes of binders, ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels are common. The grinding wheel is the one with the largest use amount and the widest use range in the grinding tool, rotates at high speed when in use, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, the inner circle, the plane, various molded surfaces and the like of a metal or nonmetal workpiece.

According to the requirements of different working conditions, different requirements are needed for the design of a working layer, and in the process of processing the existing stage difference working conditions, the stage difference is usually manually shaken out by manpower, so that the method does not meet the precision requirement in many special working conditions.

In order to realize the purpose of the utility model, the technical method is as follows:

a segment difference grinding wheel comprising:

the middle part of the dish-shaped base body is provided with a hollow flange connecting part which is provided with double circular rings and is wide at the top and narrow at the bottom;

a grinding wheel working layer fixed on the outer ring of the wide end of the disc-shaped base body;

wherein the content of the first and second substances,

one end of the grinding wheel working layer is fixed with the wide end of the disc-shaped base body, the other end of the grinding wheel working layer is a step section surface with a wide upper part and a narrow lower part, the inward contraction angle of the step section surface is 10.9-11.1 degrees, a first inclined plane is arranged at the connecting part of a first horizontal plane of the grinding wheel working layer and the step section surface, and the inclination angle of the first inclined plane is 5-7 degrees.

The beneficial effects of the utility model reside in that:

the grinding requirements of precision under different working conditions are met by the specific segment difference structure arrangement of the grinding wheel working layer.

Detailed Description

The invention is further illustrated by the following examples:

a segment difference grinding wheel comprising: the steel base comprises a disc-shaped steel base body 100 with a wide upper part and a narrow lower part, wherein a hollow flange connecting part 110 with a wide upper part and a narrow lower part and arranged in a double circular ring is arranged in the middle of the disc-shaped steel base body 100; a grinding wheel working layer 200 fixed on the outer ring of the wide end 101 of the disc-shaped steel substrate 100; the inclined surface 104 formed between the wide surface 102 and the narrow surface 103 of the disc-shaped steel substrate 100 is inclined upward by 27 °.

The thickness of the upper ring 111 of the hollow flange connecting part 110 is the same as the thickness of the grinding wheel working layer 200 and the thickness of the wide end 101 of the disc-shaped steel substrate 100, so that the grinding wheel working layer 200 is better fixed and the grinding wheel working layer 200 is prevented from falling off during high-speed grinding.

The lower ring 112 of the hollow flange connection portion 110 is disposed along the central axis of the upper ring 111, and the lower ring 112 has a diameter shorter than that of the upper ring 111.

One end 210 of the grinding wheel working layer 200 is fixedly bonded with the wide end 101 of the disc-shaped steel substrate 100, the other end 220 of the grinding wheel working layer 200 is a step section surface 221 with a wide top and a narrow bottom, the inward contraction angle of the step section surface 221 is 11 degrees, in order to better improve the grinding precision, a first horizontal surface 230 of the grinding wheel working layer 200 is connected with the step section surface 221, a first inclined surface 231 is arranged at the connection position, and the first inclined surface 231 is inclined downwards at an inclination angle of 6 degrees.

Because the structure is adopted, the utility model discloses a theory of operation lies in:

the whole segment difference grinding wheel is connected to a frame (not shown in the figure) through a hollow flange connecting part 110, and then the frame is started to drive the grinding wheel to rotate for grinding. The grinding wheel working layer 200 is driven by the disc-shaped steel base body 100 to work, and the step section surface 221 enables a grinding object to form a relative inclined table surface, namely a section difference, through the inclined arrangement of the step section surface.

The arrangement of the first inclined surface 231 provides smaller step accuracy while ensuring the fixing fastness of the grinding wheel working layer 200.

In order to realize the step difference in different directions, the whole grinding wheel for the step difference grinding can be connected to a machine frame (not shown) in a forward connection or reverse connection mode through the lower ring 112 or the upper ring 111 of the hollow flange connecting part 110.
