Abstract
The utility model relates to the technical field of bearing grinding tools, in particular to a high-accuracy high-speed bearing plane grinding device. The high-accuracy high-speed bearing plane grinding device comprises an upper grinding wheel fixed on a grinding machine and is characterized in that an annular lower grinding plate is fixedly installed at the position, corresponding to the position right below the upper grinding wheel, of the grinding machine, a plurality of chip discharging grooves are evenly formed in the upper end face of the lower grinding plate in the circumferential direction, and the chip discharging grooves penetrate through the upper end face of the lower grinding plate in the radial direction. According to the high-accuracy high-speed bearing plane grinding device, the structure of a lower grinding wheel in an existing double-end-face bearing grinding device is improved through the technical improvement, namely the existing lower grinding wheel and an existing lower grinding wheel base plate are replaced by the lower grinding plate, the structural design is carried out on the upper end face of the lower grinding plate, the chip discharging grooves are formed to enable metal chips generated in the bearing grinding process to be timely discharged, influences, caused by the accumulated chips, on bearing grinding are effectively prevented, it is discovered that the surface roughness of products machined through the high-accuracy high-speed bearing plane grinding device is improved by one level in practice, and the handing feeling and the appearance are good.
Description
Technical field
The utility model relates to the mill processing tool technical field of bearing, specifically a kind of high-precision high-speed bearing plane lapping device.
Background technology
At a high speed, the processing of the mill of high-precision bearing is divided into thick, essence, grinds, at grinding step, the raceway groove of bearing forms, the datum level of bearing ring is not wished grinding again, but is that non-datum level also has the surplus of several to need reconditioning.As shown in Figure 1, what on double-ended grinding machine, make at present is each emery wheel (upper emery wheel 6 and be installed on the lower grinding wheel 4 on lower grinding wheel base plate 2) up and down, the correction of plane of grinding wheel degree repairs with diamond pen, in production process, often there is the irregular situation of emery wheel, have influence on the depth of parallelism of institute's grinder part, the unstable product quality that causes processing, two emery wheels carry out grinding to two planes simultaneously, have destroyed the original precision of bearing.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of high-precision high-speed bearing plane lapping device, adopts this lapping device grinding bearings lasso plane, can realize the stay-in-grade object of the lasso part depth of parallelism.
According to the technical solution of the utility model: a kind of high-precision high-speed bearing plane lapping device, comprise the upper emery wheel being fixed on grinding machine, it is characterized in that: abrasive sheet under annular corresponding to fixed installation under described upper emery wheel on grinding machine, described lower abrasive sheet upper surface is along the circumferential direction uniform offers some chip areas, and described chip area radially connects lower abrasive sheet upper surface.
As further improvement of the utility model, locating hole is offered at the center of described lower abrasive sheet, and lower abrasive sheet bottom end face offers fixing threaded hole.
As further improvement of the utility model, described lower abrasive sheet is provided with step corresponding to upper end, locating hole place.
As further improvement of the utility model, described lower abrasive sheet is cast iron plate.
Technique effect of the present utility model is: the utility model is by technological improvement, lower grinding wheel structure in existing Double End bearing grinding device is improved, by a lower abrasive sheet, replace existing lower grinding wheel and lower grinding wheel base plate, and carry out structural design in lower abrasive sheet upper surface, offer place's chip area, the metal fragment producing in bearing grinding process is discharged in time, the chip that effectively prevents accumulation impacts bearing grinding, the product surface roughness of finding in practice the utility model processing improves one-level, and feel outward appearance is good.
Accompanying drawing explanation
Fig. 1 is existing double-ended grinding machine grinding structure schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is the top view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1 ~ 3, comprise fixing threaded hole 1, lower grinding wheel base plate 2, locating hole 3, lower grinding wheel 4, grinding workpiece 5, upper emery wheel 6, lower abrasive sheet 7, chip area 8, abrasive sheet working face 9, grinding workpiece datum level 10, step 11 etc.
As shown in Figure 2 and Figure 3, the utility model is a kind of high-precision high-speed bearing plane lapping device, comprise the upper emery wheel 6 being fixed on grinding machine, abrasive sheet 7 under annular corresponding to fixed installation under described upper emery wheel 6 on grinding machine, lower abrasive sheet 7 upper surfaces are abrasive sheet working face 9, described lower abrasive sheet 7 upper surfaces are along the circumferential direction uniform offers some chip areas 8, and described chip area 8 radially connects lower abrasive sheet 7 upper surfaces.
Locating hole 3 is offered at the center of lower abrasive sheet 7 so that can be accurately by lower abrasive sheet 4 location and installation on grinding machine, lower abrasive sheet 7 bottom end faces offer fixing threaded hole 1.
Lower abrasive sheet 7 is provided with step 11 corresponding to locating hole 3 upper ends, place.
Lower abrasive sheet 7 is cast iron plate, integral cast moulding.
The utility model course of work is as follows: before grinding grinding workpiece 5, first upper emery wheel 6 is regulated with lower abrasive sheet 7, guarantee that axial runout can not surpass 0.002mm in process, grinding workpiece datum level 10 is contacted with the abrasive sheet working face 9 of lower abrasive sheet 7, (while grinding lasso, datum level down, contact with abrasive sheet 7) after carrying out above-mentioned preparation, by technological requirement, grind, ground rear taking-up grinding workpiece 5, generally all within the scope of 1um, (after grinding, the index plane size of lasso does not change the depth of parallelism substantially that find on inspection workpiece, just grind the burr of 1 to 2 micron), the surface roughness of datum level improves one-level simultaneously, feel outward appearance is good.
The utility model is by technological improvement, lower grinding wheel structure in existing Double End bearing grinding device is improved, by a lower abrasive sheet, replace existing lower grinding wheel and lower grinding wheel base plate, and carry out structural design in lower abrasive sheet upper surface, offer place's chip area, the metal fragment producing in bearing grinding process is discharged in time, effectively prevent that the chip of accumulation from impacting bearing grinding.
