Description
Technical field
The utility model relates to a kind of grinding wheel more particularly to a kind of high thickness grinding wheels of combination.
Background technique
Grinding wheel is that abrasive material is consolidated into certain shapes, and the bonded abrasive tool with some strength by bonding agent；Its generally by
Abrasive material, bonding agent and stomata are constituted, this three parts 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；Grinding wheel is that dosage is maximum in grinding tool, uses
The most wide one kind in face, high speed rotation when use can outer circle, inner circle, plane and various type faces etc. to metal or non-metal workpiece
Roughly ground, partly refine and refine and slot and cut off etc.；Thickness with the development of mechanical processing industry, for centreless grinding
Greater than the high thickness grinding wheel of 500mm using increasingly extensive, but the thickness of grinding wheel is higher, and the difficulty and cost of production are also bigger, and one
It is the hydraulic press for needing large-tonnage, equipment investment is big；Second is that critical technological point is more, since pressure passes grinding wheel in molding pressing process
It passs and gradually lacks, it is difficult to ensure that the density and hardness at the upper, middle and lower position of grinding wheel is consistent, cause grinding wheel in grinding process
In each position consumption it is inconsistent, ideal ground effect is not achieved, and need to often modify, not only reduces labor productivity, but also
Cause grinding wheel consumption big, therefore, when production, usually feeds intake several times when molding feeds intake and smash pressure, and it is consistent in the hope of hardness,
But will cause the density of grinding wheel, nonuniform organization, balance quality does not reach requirement, meanwhile, high thickness grinding wheel in drying, be burnt into
It is easy to the defects of aliquation, crackle, deformation occurs in journey, seriously affects product quality and economic benefit, currently, producer is more mostly
It is ground together using the grinding wheel clamping of two panels or the above same size, but can be because of monolithic grinding wheel when the assembling of multi-disc grinding wheel
The depth of parallelism, balance, outer diameter and hole size etc. difference, assemble extremely difficult and time-consuming, and also needed after being completed
Secondary operation is carried out, working efficiency is influenced, is bonded together there are also grinding wheel manufacturing firm using multi-disc grinding wheel and constitutes height
Thickness grinding wheel, but since there are problems for its bonding plane adhesive strength, it is processing, in detection process, is being easy to happen phenomenon of rupture.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of high thickness grinding wheel of combination, and production is held
Easily, high, at low cost, using effect the is good high thickness grinding wheel of adhesive strength.
To achieve the above object, the technical solution of the utility model is: a kind of high thickness grinding wheel of combination, including top sand
Wheel, intermediate grinding wheel and bed load wheel, it is characterised in that: the top grinding wheel center is provided with heavy square hole and center round tube hole, the center
Round tube hole is located in heavy square hole, and the intermediate grinding wheel center is provided with square through hole, and bed load wheel center is equipped with convex block, bed load
It is provided with through-hole at the center of wheel and convex block, which is glued whole at one in the heavy square hole of intermediate grinding wheel insertion top grinding wheel
Body.
The bed load wheel and convex block casting are integral, and the cross section of the convex block is square.
The square through hole at the intermediate grinding wheel center is square through-hole, and side length is greater than convex block cross section side length 0.1mm.
The depth of the heavy square hole at the top grinding wheel center is the thickness of 1/2 top grinding wheel.
The diameter of the through-hole is less than the 1/2 of convex block cross section side length.
The beneficial effects of the utility model are: the utility model is designed reasonably, structure novel, due to the thin grinding wheel set of multi-disc
It is integral to connect bonding, solves the problems, such as that the manufacture difficulty of the high thickness grinding wheel of monoblock type is big, cost of investment is high, has been effectively ensured close
Degree, hardness, structural homogenity；Since high thickness grinding wheel is using bed load wheel, intermediate grinding wheel, top grinding wheel three parts composition, bed load
The convex block of wheel is formed with intermediate grinding wheel, top grinding wheel socket gluing, and the high thickness of grinding wheel can be high by changing the convex block of bed load wheel
The quantity of degree and intermediate grinding wheel arbitrarily adjusts, and can efficiently produce different high thickness grinding wheels, at the same adjacent thin grinding wheel socket with
It bonds together, effectively increases the bond strength of bonding plane, ensure that the success rate in processing, detection process, not only mention
High product quality, and the revolving strength of product has obtained effective raising, so that usage safety performance is further mentioned
It rises, and when pushing up grinding wheel and wearing, can replace top grinding wheel, in-between grinding wheel and bed load wheel can also continue to using avoiding entirely
Portion's replacement, reduces costs.
