Abstract
The utility model relates to a grindstone, which belongs to a grinding tool, the cap of which is divided into three layers. The upper layer is made from non-woven fabric mixed resin, the middle layer is made of glass fiber reinforcement nets, and the lower layer is made of the combination of carborundum and phenolic resin. The carborundum is made by mixing adamantine spar and carbofrax. A mounting hole which is prepared for a mechanical axis to pass and extend and in the centre of the cap of the grindstone is a ring of galvanized iron. The cap of the grindstone is compactly and firmly bonded with the P V A sponge grindstone ring by the adhesion of the epoxy resin mixed curing agent. The mixed carborundum in the lower layer of the cap of the grindstone can still grind the work piece after the grindstone ring is used. The grindstone has the characteristics of long service life, material saving, etc.
Description
Technical field
The utility model relates to a kind of grinding tool, particularly a kind of emery wheel.
Background technology
Existing emery wheel grinding tool mainly is made up of with the emery wheel ring the emery wheel lid, and its emery wheel lid generally all is paper lid or vinyl cover, and this emery wheel is easy to generate spot stripping phenomenon in use, and service life is shorter.Chinese patent notification number CN2164342Y, open day on May 11st, 1994, invention and created name is " structure of abrasive wheel ", this application case discloses the emery wheel lid and has constituted reticulate body by cross one another glass fibre, adopt binding agent and grinding ring to combine, reach the prolongation emery wheel effect in service life.No matter be that paper lid, vinyl cover or glass fibre lid closes with the emery wheel loops, that its emery wheel lid only plays is fixing, and for the effect of stretching through of mechanical axostylus axostyle, do not have other new use value.
Summary of the invention
Technical problem to be solved: the utility model provides a kind of can playing with the emery wheel ring to bond firmly at the prior art deficiency, and has the emery wheel lid that grinds function again.
Technical scheme: the utility model is made of PVA sponge emery wheel ring and multi-functional emery wheel lid, described emery wheel lid divides three-decker, the upper strata is the adhesive-bonded fabric hybrid resin, the intermediate layer is that glass fibre strengthens net, lower floor is diamond dust and phenolic resins mixed structure, and this diamond dust is made of corundum, carborundum mixing; Described emery wheel lid installing hole central, that stretch through for mechanical axostylus axostyle is the tinplate ring, this emery wheel lid combines by the bonding close and firm that makes it of epoxy resin mixed hardening agent with PVA sponge emery wheel ring, after this emery wheel ring used, the lower floor of described emery wheel lid mixed diamond dust and still can grind workpiece.
The utility model has following advantage:
1, described emery wheel lid is by upper strata adhesive-bonded fabric hybrid resin, and the intermediate layer is that glass fibre strengthens net, and lower floor is that diamond dust and phenolic resins mix formation, and this emery wheel lid combines by the epoxy resin mixed hardening agent with the emery wheel ring, has the characteristics of long service life.
2, described emery wheel lid replaces paper lid, vinyl cover or the glass fibre lid of use in the past, has increased its new performance, and after the emery wheel ring used up, this emery wheel lid still had the grinding function, has saved material.
Fig. 1 is that the utility model emery wheel ring combines schematic diagram with the emery wheel lid.
Fig. 2 is the emery wheel lid structural representation among Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: described emery wheel lid 1 is made up of three-decker, the upper strata is an adhesive-bonded fabric hybrid resin 6, the intermediate layer is that glass fibre strengthens net 4, and lower floor is diamond dust and phenolic resins mixed structure 5, and described diamond dust is mixed and formed by corundum, carborundum.Cover 1 central authorities at described emery wheel and establish a tinplate ring 2, supply the axostylus axostyle of mechanical body to stretch through; When this emery wheel lid 1 combines with PVA sponge emery wheel ring 3, use the epoxy resin mixed hardening agent to be adhesive, Here it is the utility model emery wheel grinding tool.Because described emery wheel covers 1 lower floor and is made up of diamond dust and phenolic resins mixed structure 5, so after PVA sponge emery wheel ring 3 had been ground, remaining emery wheel lid 1 still had grinding use value.
Claims (4)
1, a kind of emery wheel comprises the emery wheel ring, it is characterized in that: it is that glass fibre strengthens net, lower floor is that diamond dust and phenolic resins mixed structure constitute for adhesive-bonded fabric hybrid resin, intermediate layer that emery wheel covers layer.
2, emery wheel according to claim 1 is characterized in that: it is the tinplate toroidal ring structure that emery wheel covers central installing hole.
3, emery wheel according to claim 1 is characterized in that: the emery wheel ring is a PVA sponge emery wheel ring structure, and the adhesive between this emery wheel ring and the emery wheel lid is the epoxy resin mixed hardening agent.
4, emery wheel according to claim 1 is characterized in that: diamond dust is corundum, carborundum mixed structure.
