Description

Diamond grinding wheel for grinding hard alloy balls

Technical Field

The utility model mainly relates to the field of grinding tools for grinding hard alloy balls, in particular to a diamond grinding wheel for grinding hard alloy balls.

Background

The hard alloy precision ball has the characteristics of high strength, high precision, high temperature resistance, corrosion resistance and the like, and is widely applied to the aspects of valve ball sealing in the petroleum industry and the like.

Generally, the grinding disk on the emery wheel adopts plane resin diamond emery wheel, and lower grinding disk channel adopts V-arrangement groove cold pressing impregnated diamond, and the main problem that this kind of processing grinding apparatus exists is: the diamond layer thickness of upper and lower abrasive disc is thinner, and diamond layer consumes soon, need frequently to change the diamond emery wheel of upper abrasive disc and the diamond of impregnated abrasive disc down again.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a diamond grinding wheel for grinding a hard alloy ball, which comprises a grinding wheel disc 1, wherein the grinding wheel disc 1 is of a bowl-shaped structure, a diamond grinding layer 2 is sleeved on the upper end of the grinding wheel disc 1, the grinding wheel disc 1 and the diamond grinding layer 2 are bonded through resin, and a semicircular groove 3 is formed in the outer side wall of the diamond grinding layer 2.

Preferably, the semicircular groove 3 has a circular ring structure.

Preferably, the semicircular groove 3 is located at the center of the outer side wall of the diamond abrasive layer 2.

Preferably, the center of the lower end of the grinding wheel disc 1 is provided with a mounting hole 4.

Preferably, the upper edge and the lower edge of the mounting hole 4 are chamfered.

The utility model has the beneficial effects that: simple structure can dismantle the change, easy maintenance, and the terminal surface of diamond grinding layer can be used for the carbide of grinding conventional form, and the side of diamond grinding layer is used for the grinding carbide ball, and a part is dual-purpose, has avoided changing the emery wheel time promptly, has improved grinding efficiency again.
