Description
【Technical field】
The present invention relates to bearing mnanufacture field, and in particular to a kind of measurement apparatus of bearing seal groove location and its measurement side
Method.
【Background technology】
Known, bearing has been widely applied in all trades and professions, in the process of bearing, in order to ensure bearing
Quality reaches design requirement, often the relative dimensions of bearing after processing is measured, and wherein survey crew is to bearing holder (housing, cover)
When seal groove on circle is measured, the method for generally adopting is " to be defined as β angles, hereinafter referred to as β in the bearing seal groove angle conical surface
Angle " diametrically " be defined as φ Dx, hereinafter referred to as φ Dx " survey height " being defined as height h, hereinafter referred to as height h "；At present originally
The measuring method that art personnel commonly use mainly has following several：
The first measuring method is test desk method：Special stepped measurement is processed first against the model of measurement bearing
Platform, is provided with the conical surface being engaged with bearing ring seal groove pyramidal plane, its frustoconical bevel angle etc. below test desk lower step
In β angles, the height of the lower step of test desk is ho, and external diameter is equal to φ Dx, secondly test desk is placed in the sealing of bearing ring
Behind the surface of groove conical surface φ Dx, the assembly of bearing ring and test desk is placed on the substrate of altitude meter, steadily pushes away its combination
Body makes assembly be placed under the gauge head of height survey table, and " i.e. test desk lower step is upper on the metering face of gauge head sensing test desk
On face ", now the aobvious apparent size of survey table is designated as hx, the hx=h+ho for measuring, so measurement target size h=hx-ho；Using this kind of
The shortcoming of survey method is：The test desk accuracy of manufacture has high demands, examines and determine difficult and manufacturing cost height；Simultaneously because test desk enters from great
And causing high labor intensive, inefficiency when measuring operation, operating personnel easily cause test desk and axle in measurement process
The bump injury of bearing ring and caused measurement misalignment；Because the conical surface of measured bearing lasso is Vehicle Processing, and then cause bearing
The lasso seal groove conical surface is poor with the stickiness of the test desk conical surface, reduces certainty of measurement, and main is due to the measurement of this kind of method
It is not direct measurement, and then cause measure error to increase etc..
Second measuring method is limit model mensuration：Design and manufacture sample plate by detection requirement first, measure
The side of model is big model, and another side is little model, when big model can fall bottom, little model fall not on earth when, then workpiece is qualified, this kind of survey method
Can only qualitatively judge with vision and tactile, the precision of detection is relatively low, it is strict to the skill set requirements of testing staff, will for precision
Higher workpiece is asked to measure using the method.
The third measuring method is that contourgraph surveys method：Tested bearing ring is placed on the substrate of contourgraph first, is adjusted
Head is picked up in survey, then from basal plane to impact point, measurement result intelligent digital, the certainty of measurement of above-mentioned metering system by machine quality
Determine, for the machine of different brands, its precision is widely different, and for the machine of some high precisions, acquisition expenses is prohibitively expensive,
And most of brands are technically still immature, it is only suitable at present for laboratory, should not be used in the batch inspection of working face.
【The content of the invention】
