Abstract
The utility model discloses a cubic boron nitride grinding wheel provided with an axial trough mortar, which comprises a grinding wheel base body that is provided with a central shaft. The cubic boron nitride grinding wheel is applicable to grinding a groove of a part cylinder in a rotating-type compressor of a domestic air conditioner. By adopting the grinding wheel with the structure, as the central shaft is directly arranged on the grinding wheel base body, the matching between an inner hole and a bearing and the matching between the bearing and the central shaft in the prior art are omitted, and the matching among parts of the grinding wheel is reduced, therefore, the stability and the clamping accuracy of the grinding wheel are improved, the quality of the grinding wheel is improved, the service life thereof is prolonged, the accuracy of the processed product is increased, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of axle groove and grinds cubic boron nitride abrasive wheel.
Background technology
A groove of a part cylinder will come grinding with the plating cubic boron nitride abrasive wheel, the required precision of this groove grinding height very in the domestic air conditioning rotary compressor.Technological requirement is: below the roughness 4um, below the parallel plane degree 4um, below the linearity 4um.The groove that present cylinder is used grinds emery wheel has endoporus not have axle, and the installation way of emery wheel is: cover one bearing in the emery wheel endoporus, in dead eye, overlap a central shaft then again, and rise with bearing holder (housing, cover) at the two ends of central shaft again, on the emery wheel bracket of packing at last.This emery wheel has passed through the emery wheel endoporus and has cooperated with bearing and emery wheel bracket with central shaft, central shaft with bearing, bearing, and one has four cooperations.Because the tolerance that cooperates that repeatedly cooperated invisible increase of part.Directly influenced the precision of emery wheel.And axle groove grinds the cubic boron nitride abrasive wheel work in-process and comes the stable equilibrium by hydraulic pressure, particularly when emery wheel is worked into mid-term or middle and later periods, the emery wheel sand grains is more and more blunt, the resistance of processing can be increasing, because of the cooperation between emery wheel too much, the stability that emery wheel quiver easily takes place has influenced emery wheel directly causes product parallel plane degree overproof, thereby causes emery wheel to be scrapped.Not only influence processing quality, also improved production cost.Therefore, how to address the above problem, become problem demanding prompt solution.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, long service life, axle groove that machining accuracy is high grinds cubic boron nitride abrasive wheel.
In order to solve the problems of the technologies described above, a kind of axle groove of the present utility model grinds cubic boron nitride abrasive wheel, and this emery wheel comprises grinding wheel base body, and wherein grinding wheel base body is provided with central shaft.
Above-mentioned axle groove grinds cubic boron nitride abrasive wheel, and described grinding wheel base body is provided with the axis hole of fixed center axis.
Above-mentioned axle groove grinds cubic boron nitride abrasive wheel, and described central shaft and grinding wheel base body are structure as a whole.
Above-mentioned axle groove grinds cubic boron nitride abrasive wheel, and the longitudinal section of described grinding wheel base body circumference is a V-type, and this circumferential surface is provided with cbn layer.
Axle groove of the present utility model grinds the groove that cubic boron nitride abrasive wheel is mainly used in a part cylinder in the grinding domestic air conditioning rotary compressor.The emery wheel that adopts this kind structure has saved that endoporus cooperates with central shaft with bearing, bearing in the prior art because central shaft is set directly on the grinding wheel base body, has reduced twice cooperation between the emery wheel parts; When central shaft is structure as a whole with grinding wheel base body, reduced between the emery wheel parts three times and cooperated, thereby improved the stability and the clamping precision of emery wheel, improved emery wheel quality, service life and converted products precision, reduce production costs.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, a kind of axle groove grinds cubic boron nitride abrasive wheel, comprises grinding wheel base body 1, and the longitudinal section of its circumference is a V-type, and this circumferential surface is provided with cbn layer 2, and grinding wheel base body 1 is provided with axis hole 4, is used for fixing central shaft 3.
Certainly, grinding wheel base body 1 of the present utility model can also and central shaft 3 do into a single integrated structure.
