Description

Knockeout core cymbal shaped grinding apparatus

Technical field

The utility model relates to grinding tool, is a kind of Knockeout core cymbal shaped grinding apparatus.

Background technology

At present, the cymbal shaped grinding apparatus of producing in the grinding materials and grinding tool industry is mounted on the electric angle grinder, in fair speed rotation by the friction on machined object surface being played grinding, polishing action rubbing down instrument.The whole thing of the cymbals shape that cymbal shaped grinding apparatus adopts abrasive grain, bond and matrix to make, belong to expendable consumed product, the outward flange of the whole thing of cymbals shape will dwindle to centre bore gradually in the grinding, extend to the restriction that is subjected to sanding machine guard shield and work angle always and stop use, calculate to out of use diameter from the outward flange diameter, practical application efficient lower caused the bigger waste of social resources.

Cymbal shaped grinding apparatus is mainly used in the metallic article process industry, the electric angle grinder guard shield blocks owing to be subjected to operating machine, use China and foreign countries edge diameter is dwindled, can be subjected to making the work angle restriction again, its availability generally is lower than 60% of original volume, remainder is discarded because of not using, and causes the raising of production, use cost thus.Moreover making because of it that material belongs to substantially can not the natural decomposition thing, adds that the social demand amount is big, brings bigger problem of environmental pollution, does not cause the great attention of the industry so far as yet, in putting on the agenda.

In fact the global shape of cymbal shaped grinding apparatus can be decomposed into the outward flange abrasive disc of bearing the rubbing down effect and bear core grinding two major parts of bed hedgehopping, power transmission and integrated support effect, and the two becomes one existing cymbal shaped grinding apparatus, and is indivisible.Just caused the low reason place of utilization rate of this grinding tool.

Summary of the invention

For overcoming the deficiency of above-mentioned existence, the utility model purpose is to provide a kind of Knockeout core cymbal shaped grinding apparatus and preparation method to this area, make it can solve existing like product and constitute that design is owed rationally, preparation method is owed desirable technical problem, the purpose of this utility model realizes by the following technical solutions.

The utility model is analyzed by its each self-applying at first to the actual function of use of existing cymbal shaped grinding apparatus, can be divided into abrasive disc position and core grinding position.Existing cymbal shaped grinding apparatus has only an independent cymbals body, no matter the cymbal shaped grinding apparatus that adopts which kind of abrasive material, bond, matrix to make, its cymbals shape part and planar section all are non-removable integral body, after it finishes polishing or grinding function to greatest extent, about 40% the residue that stays and going out of use, but and these discarded objects parts exactly have the material that higher-value can't be recycled.The utility model is a kind of detachable assembly, and it is that abrasive disc by the peaceful shape of core grinding part of cymbals body partly combines.Wherein core grinding by descending core grinding, movable liner plate, last three assemblies of core grinding to synthesize, is born bed hedgehopping, power transmission and the integrated support effect of cymbal shaped grinding apparatus again.Core grinding partly adopts metal material to manufacture, can use repeatedly, and durable in use; The abrasive disc part of flat shape can adopt different abrasive materials, bond, matrix to make according to polishing or grinding process needs.

A kind of Knockeout core cymbal shaped grinding apparatus, this grinding tool comprises abrasive disc, its main points are that the core grinding abrasive disc is combined as cymbal shaped grinding apparatus, core grinding is divided into core grinding and last core grinding down, the internal diameter of abrasive disc is provided with the profile of tooth concave surface, and the external diameter of following core grinding is provided with the profile of tooth convex surface, and the profile of tooth concave surface of abrasive disc disjunctor is meshed with the profile of tooth convex surface of following core grinding disjunctor, promptly descending core grinding is initiatively transmission, the passive transmission of abrasive disc; The side of described abrasive disc, time core grinding is provided with movable liner plate, and the through hole of following core grinding, last core grinding is fixedlyed connected with the electric angle grinder main shaft.

The following core grinding of described Knockeout core cymbal shaped grinding apparatus and abrasive disc profile of tooth mesh or are made as trapezoidal engagement.

The following core grinding of described Knockeout core cymbal shaped grinding apparatus and abrasive disc profile of tooth mesh or are made as the engagement of other geometry.

The cymbal shaped grinding apparatus of described core grinding abrasive disc combination is made as flat shape grinding tool in addition, core grinding is divided into left core grinding and right core grinding, the internal diameter of abrasive disc is provided with the profile of tooth concave surface, and the external diameter of left core grinding is provided with the profile of tooth convex surface, and the profile of tooth concave surface of abrasive disc disjunctor is meshed with the profile of tooth convex surface of left core grinding disjunctor.

Above-mentioned described following core grinding, last core grinding, left core grinding, right core grinding are that the spy illustrates in addition by the name of practical operation orientation.

Polishing, the ablation of cymbal shaped grinding apparatus born in above-mentioned design.Keep the existing original function of cymbal shaped grinding apparatus, also effectively improve its operating characteristics and safety coefficient.

The described number of teeth is then according to diameter, the material of abrasive disc, and the workpiece that is ground is relevant, increases or reduces.

By connected mode, the preparation method of said structure, just high through abrasive disc utilization rate that grinding consumed, remainder is that abrasive disc matches with following core grinding near the profile of tooth concave, convex face of through hole.

Knockeout core cymbal shaped grinding apparatus is that the core grinding partial design that will bear bed hedgehopping, power transmission and integrated support effect becomes to use metallic object repeatedly, thereby the discarded object after grinding tool uses reduces to about 10% by original about 40%.The utility model reasonable in design, preparation method is feasible.Realized the effect of saving resource, reducing cost, reducing pollution, the social demand amount is big, and market prospects are good, have good social value and an economic worth.
