Description
Technical field
The utility model belongs to emery wheel field, is specifically related to a kind of coreless grinding wheel be in groups arranged on centerless grinder.
Background technology
Centerless grinder does not need to adopt the axle center of workpiece and implements a class grinding machine of grinding, its in groups coreless grinding wheel adopt 2 to 3 emery wheels to combinationally use, dimension precision requirement is high, and difficulty of processing is large.Domestic centerless grinder uses emery wheel in groups to use the centerless grinder emery wheel in groups of Saint-Gobain, the Mitsui grinding of Japan, the warm top grade foreign well-known emery wheel manufacturing enterprise of Germany always, and cost is very high.Domestic processing producer is also trying every possible means to realize production domesticization, but domestic processing producer generally adopts multiple stage grinding machine to process respectively the thickness of monolithic emery wheel, aperture, outside dimension, and then assemble, so just occurred a lot of problem, one is that emery wheel dimensional discrepancy and form and position tolerance are inconsistent; Two is cannot install because the emery wheel after combination is too thick; Three is because the emery wheel static unbalance after combination dubs skewness and affects the static balance performance of emery wheel group.By analysis, the reason of the problems referred to above is processed respectively due to plane, aperture, external diameter, and the perpendicularity in abrasive wheel end face and aperture is bad (hole deviation), the reason such as cause the end face run-out of emery wheel excessive.
Utility model content
The purpose of this utility model is to solve prior art domestic coreless grinding wheel in groups and has that machining accuracy difference, assembly difficulty are large, the defect of static balance poor performance, provides the coreless grinding wheel in groups that a kind of machining accuracy is high, assembly difficulty is little, static balance performance is good.
The technical solution adopted in the utility model is:
One is coreless grinding wheel in groups, comprise 2-3 sheet emery wheel, it is characterized in that the installing hole place of every sheet emery wheel is all processed with inner groove, the excircle side of every sheet emery wheel is equipped with static balance tag line, emery wheel group shape in groups after, the static balance tag line of all emery wheels is positioned on 1 straight line.
Inner groove is positioned at the middle part of the installing hole of emery wheel, and the diameter of inner groove is the large 1-2mm of installing hole diameter, and the groove width of inner groove is the 50-60% of grinding wheel thickness.
Inner groove of the present utility model, the contact area (the more large more bad installation of contact area) between emery wheel aperture and grinding machine spindle can be reduced, thus the frictional force reduced between emery wheel aperture and grinding machine spindle, reduce the difficulty of processing of installing hole, alleviate assembly difficulty, convenient installation.
The utility model is made up of 2-3 sheet emery wheel, in order to ensure the static balance of emery wheel in groups, static balance tag line established separately by every sheet emery wheel, in groups during emery wheel assembling, the static balance tag line on the every a slice emery wheel in same group of emery wheel can be made all to be positioned on 1 straight line, the static balance of the every a slice in same group of emery wheel can be made to dub be evenly distributed in emery wheel group, thus ensure the overall static balance of emery wheel in groups.
Emery wheel dimensional accuracy of the present utility model is high, in one group of (2 ~ 3) emery wheel, outside dimension difference is not more than 1mm, gauge is not more than 0.2mm, end face run-out is not more than 0.05mm, static balance grams is strict in national regulations value 50%, and Wheel hardness, even tissue are consistent, can realize synchronous finishing, synchro-feed, synchronous grinding.Grinding workpiece shape retention is good, and dimensional accuracy is high.
Technological process of the present utility model:---fine finishining---is burnt till---in loading of kiln in bonding agent processing-mixed ingredients-shaping-drying.
The utility model has the advantage that machining accuracy is high, assembly difficulty is little, static balance performance is good.Use the utility model completely can the outer imported product of subrogate country, reduction use cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
As shown in FIG.: 1. emery wheel; 2. installing hole; 3. inner groove; 4. static balance marking line.
Detailed description of the invention
As shown in Figure 1 and Figure 2: the utility model in groups emery wheel is made up of 3 emery wheels 1, an inner groove concaved is processed with in the middle part of the installing hole of every sheet emery wheel 1, the excircle side of every sheet emery wheel 1 is provided with static balance marking line 4, and during assembling, the static balance marking line 4 of 3 emery wheels is positioned on 1 straight line.
When the utility model makes, step is as follows:
1, shaping: to adopt emery wheel industry state-of-the-art isostatic pressing process, consistent along the tissue in grinding wheel diameter direction, even density, balance grams adds tight 50% than national regulations value, and uniformity of hardness is only 40% of national regulations value.
Moulding press is installed magnetic railings ruler (our company's patented technology), controls grinding wheel thickness size, guarantee Wheel hardness accordance and stability.
Because this emery wheel belongs to high thickness product, for guarantee along the hardness in grinding wheel thickness direction and even density consistent, we have employed step feeding, stir material, pressing process, after feeding intake each time, all use isostatic pressing process to suppress.
2, size fine finishining
Adopt vertical numerical control diamond grinders' dop processing grinding wheel plane, aperture and cylindrical.Add man-hour, an end face of first processing grinding wheel on grinding machine, and then processing grinding wheel aperture, last processing grinding wheel external diameter.
The GB permissible value of grinding wheel characteristics and the actual index contrast table of the utility model
Can be found out by upper table, the utility model completely can imported product outside subrogate country.
