Description
Technical field
Cover is taken turns the present invention relates to one kind, a kind of new grinding wheel cover is referred in particular to.
Background technology
Traditional sanding and polishing piece, covers and combines by being bonded at plastics or web.There is many weak points in it,
1）Because motor rotates at a high speed, heat is largely produced, traditional fibre square or plastics cover are easily caused radiating deficiency, so that
Plant equipment temperature is too high to cause failure；2）Traditional cover upper surface is some ring type deep troughs or is plane, due to glue tool
There is permeability, the depth of ring type deep trough is deeper, the glue on groove is largely penetrated into ring type deep trough, on the one hand influence is pasted
Quality, on the other hand needs to consume more glue, cost is higher, and the cover bonding strength of plane is inadequate；3）Traditional grinds
Mill class product is used and installation method is：On the threaded rod for slice, thin piece being put into machine electrician tool；Pass through multiple nut checks
Mode fastens abrasive disk；After product is finished, nut must be unclamped again, unloaded using the product finished.This is not only being used
In considerably increase abrasive product using install time.And if the nut on machine was even lost in last time using rear damage
Lose, whole grinding and polishing wheel will be unable to use, and cause its short life；4）Traditional sanding and polishing piece realizes nut lock to coordinate
Tight mounting means, internal aperture is larger, so that milling area reduces, influences grinding quality.
The content of the invention
The invention provides a kind of new grinding wheel cover, its object is to solve traditional abrasive wheel cover mounting means not
Easy heat radiation and glue do not consume many technical problems to preferable, cover.
A kind of new grinding wheel cover, including cover body, the center of the cover body offer through hole, around the through hole
Protrude to form circular protrusions to downside, the circular protrusions upper side is formed in corresponding annular groove, the through hole provided with interior
Screw thread, all portions of the circular protrusions uniformly offer heat emission hole, and the heat emission hole is oblique type heat emission hole.
Wherein, a convex tendon is provided with the annular groove between two neighboring heat emission hole, the two ends of the convex tendon connect respectively
Two madial walls of annular groove are connected to, each convex tendon is uniformly arranged along through hole is circumferential.
Wherein, all portions of the circular protrusions include being formed between several oblique type blades, the adjacent oblique type blade of each two
One oblique type heat emission hole.
Wherein, the cover body upper side is staggered to form latticed rhombus shallow slot by some raised lines being uniformly arranged.
Wherein, end face offers some annular size tubs by the center of circle of cover center on the upside of the cover body.
Wherein, the cover body is connected in dark fund steel wheel, wool wheel or sponge wheel.
Wherein, the plastics cover that the cover body is formed in one.
The utility model lead to more traditional abrasive wheel cover for have it is easy for installation, thermal diffusivity is good, and bonding effect is good, save
The characteristics of glue quantity.On the inside of groove be provided with internal thread, can easily enable abrasive wheel cover directly with external screw thread
Rotating shaft be directly attached, and it is straight to reduce the endoporus of the sanding and polishing pieces such as NCC abrasive wheel, wool wheel, sponge wheel
Footpath, so as to increase milling area, lifts grinding effect.Oblique type heat emission hole is formed by multiple oblique type blades, can effectively be made
Heat in rotation process is discharged from heat emission hole.And the setting of oblique type blade can reduce what gas in rotation process was discharged
Resistance, improving radiating effect and the speed for being difficult influence rotation.Latticed rhombus shallow slot is designed to glue by rhombus shallow slot
Water is held, make glue be uniformly distributed in groove and raised line on, and by experimental results demonstrate, it is this design on the one hand can save
Glue quantity is saved, the intensity of bonding is on the other hand improved.
