Abstract
In the form of annular discs the invention discloses a kind of diapsid concretion abrasive wheel, there is through hole in center, and through hole through-thickness part is circular hole, is partly polygonal hole；The circle of circular hole is the polygonal inscribed circle of polygonal hole.Reasonable in design, structure of the invention is novel.Because the hole portion of emery wheel uses diapsid, during assembling, main shaft is passed through from through hole, it is another to there is special fixture to be embedded in polygonal hole and be fixed on main shaft, so that the circular runout of emery wheel is limited, will not be because fit clearance is big and produces vibration when high speed rotates, both the precision of grinding had been improved, security performance is improved again, the effect of accurate grinding is reached, economic benefit is obvious.
Description
Technical field
The present invention relates to a kind of machining concretion abrasive wheel, particularly a kind of diapsid concretion abrasive wheel.
Background technology
Emery wheel is that abrasive material is consolidated into definite shape by bonding agent, and the bonded abrasive tool with some strength.Its it is general by
Abrasive material, bonding agent and stomata are constituted, and this three part is frequently referred to the three elements of bonded abrasive tool.According to the different classifications of bonding agent, often
That sees has vitrified bonded grinding wheel, resin bond wheel, rubber bonded grinding wheel.Emery wheel is that consumption is maximum in grinding tool, used
Face most wide one kind, rotates at a high speed when using, can be to metal or the cylindrical of non-metal workpiece, inner circle, plane and various type faces etc.
Roughly ground, half refines and fine grinding and fluting and cut-out etc..Emery wheel majority is circle, and center has through hole to be circular hole, in disk
Shape, is typically what is used under high speed rotation status.Therefore the cooperation of hole and assembled shaft is particularly significant, and fit clearance is too small in dress
Timing can cause emery wheel porous dehiscence, using dangerous；Fit clearance is excessive to produce vibration when in use, can not only influence grinding to imitate
Really, and between emery wheel and workpiece collide, explosion can be caused when serious, is damaged to personnel and equipment.Therefore, no matter
It is that international standard and national standard have all made strict requirements to emery wheel hole size.It is accurate with the development of mechanical processing industry
Grinding be increasingly widely used, the requirement of international standard and national standard to emery wheel hole size oneself can not meet demand.
But excessively accurate aperture size requirement, manufacture difficulty is larger for emery wheel manufacturing firm.
The content of the invention
Hold present invention aim to address the weak point that existing emery wheel aperture is present there is provided a kind of rational in infrastructure, making
Easily, the good diapsid concretion abrasive wheel of using effect.
The technical scheme is that：A kind of diapsid concretion abrasive wheel, in the form of annular discs, there is through hole in center, its improvements
It is that the through hole through-thickness part is circular hole, is partly polygonal hole；The circle of the circular hole is the polygonal hole
Polygonal inscribed circle.
Further scheme is：The height of the circular hole is the 1/2 of the diapsid concretion abrasive wheel thickness；The polygon
The polygon in hole is even-numbered polygons.
Reasonable in design, structure of the invention is novel.Because the hole portion of emery wheel uses diapsid, during assembling, main shaft is from through hole
Pass through, separately there is special fixture to be embedded in polygonal hole and be fixed on main shaft, so that the circular runout of emery wheel is limited, in height
It will not both be improved the precision of grinding because fit clearance is big and produces vibration, security performance improved again, reached essence during speed rotation
The effect of close grinding, economic benefit is obvious.
Brief description of the drawings
Accompanying drawing is schematic structural view of the invention.
Embodiment
Referring to accompanying drawing, further structure of the present invention is illustrated, diapsid concretion abrasive wheel 1-250*25*32-A/
F60K7V-35m/s, emery wheel external diameter is that 250mm, thickness are that 25mm, aperture are 32mm, by emery wheel body 1, octagon hole 2, circular hole
3 are constituted, and a diameter of 32mm of circular hole 3, are highly 12.5mm, and the octagon inscribe 32mm in octagon hole 2 circle is highly
12.5mm。
Claims (3)
1. a kind of diapsid concretion abrasive wheel, in the form of annular discs, there is through hole in center, it is characterized in that the through hole through-thickness part is
Circular hole, partly be polygonal hole；The circle of the circular hole is the polygonal inscribed circle of the polygonal hole.
2. the diapsid concretion abrasive wheel as described in claim 1, it is characterized in that the height of the circular hole is the diapsid containing consolidated sand
Take turns the 1/2 of thickness.
3. the diapsid concretion abrasive wheel as described in claim 1, it is characterized in that the polygon of the polygonal hole is even-numbered polygons.
