Abstract
The invention relates to the technical field of bearing grinding tools, in particular to a high-precision high-speed bearing plane grinding device which comprises an upper grinding wheel fixed to a grinding machine. The device is characterized in that an annular lower grinding plate is fixed to the position, corresponding to the right lower portion of the upper grinding wheel, of the grinding machine, the upper end face of the lower grinding plate is evenly provided with a plurality of filing discharging grooves in the circumferential direction, and the filing discharging grooves penetrate through the upper end face of the lower grinding plate in the radial direction. By means of technical improvement, the structure of a lower grinding wheel in an existing double-end-face bearing grinding device is improved, namely the lower grinding plate is used for replacing the existing lower grinding wheel and a lower grinding wheel bottom plate, structural design is carried out on the upper end face of the lower grinding plate, and filing discharging grooves are formed, so that metal filings generated in the bearing grinding process are discharged timely, influences caused by the accumulated filings on bearing grinding are effectively prevented, according to discoveries in practice, surface roughness of products machined by the device is improved by one grade, and hand feeling and appearance are good.
Description
Technical field
The present invention 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, the irregular situation of emery wheel often appears in production process, have influence on the depth of parallelism of institute's grinder part, cause the unstable product quality of processing, two emery wheels carry out grinding to two planes simultaneously, have destroyed the original precision of bearing.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of high-precision high-speed bearing plane lapping device is provided, adopt this lapping device grinding bearings lasso plane, can realize the stay-in-grade purpose of the lasso part depth of parallelism.
According to technical scheme of the present invention: a kind of high-precision high-speed bearing plane lapping device, comprise the upper emery wheel be 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 a further improvement on the present invention, locating hole is offered at the center of described lower abrasive sheet, and lower abrasive sheet bottom end face offers fixing threaded hole.
As a further improvement on the present invention, described lower abrasive sheet is provided with step corresponding to upper end, locating hole place.
As a further improvement on the present invention, described lower abrasive sheet is cast iron plate.
Technique effect of the present invention is: the present invention is by technological improvement, lower grinding wheel structure in existing Double End bearing grinding device is improved, replace existing lower grinding wheel and lower grinding wheel base plate by a lower abrasive sheet, and carry out structural design in lower abrasive sheet upper surface, offer place's chip area, the metal fragment produced in the bearing grinding process is discharged in time, the chip that effectively prevents accumulation impacts bearing grinding, find that in practice the product surface roughness that the present invention processes improves one-level, the feel outward appearance is good.
The accompanying drawing explanation
Fig. 1 is existing double-ended grinding machine grinding structure schematic diagram.
Fig. 2 is structural representation of the present invention.
The top view that Fig. 3 is Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention 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 present invention is a kind of high-precision high-speed bearing plane lapping device, comprise the upper emery wheel 6 be 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, the integral cast moulding.
The course of work of the present invention is as follows: before grinding grinding workpiece 5, at first upper emery wheel 6 is regulated with lower abrasive sheet 7, guarantee axially to beat in process and can not surpass 0.002mm, 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, with abrasive sheet 7, contact) after carrying out above-mentioned preparation, by technological requirement, ground, ground rear taking-up grinding workpiece 5, generally all in the 1um scope, (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, the feel outward appearance is good.
The present invention is by technological improvement, lower grinding wheel structure in existing Double End bearing grinding device is improved, replace existing lower grinding wheel and lower grinding wheel base plate by a lower abrasive sheet, and carry out structural design in lower abrasive sheet upper surface, offer place's chip area, the metal fragment produced in the bearing grinding process is discharged in time, effectively prevent that the chip of accumulation from impacting bearing grinding.
