Technical field
The present invention relates to the detection technique field of bearing parts, specifically a kind of bearing ring outer-diameter accuracy is accurately examined Survey device.
Background technique
Bearing ring usually will be to its outer diameter single plane size, outer diameter single plane dimensional variations amount it is oval and Mean outside diameter variation, that is, outer diameter taper is detected.The inspection of outer diameter usually carries out on D051 measuring apparatus of diameter, and D051 is straight The testing principle of cable diameter gauge is the inspection completed using comparison method Mechanical measurement principle to outer diameter.Specific detection method is such as Under: standard component is pushed into from right to left along locating platform and is measured position, adjusting lower support and aiding support position makes standard component Positioning stablity is reliable, then carries out adjusting this ruler of instrument grip cycle basis to table according to the nominal dimension of standard component and actual deviation It is very little in instrument zero position, to meter setting after measure machined good part, according to the direction and number of instrument "+" or "-" Then value compares whether measured value meets art work sheet requirement, complete the detection of lasso outer diameter.
The measurement method is for measurement outer diameter single plane size and outer diameter single plane dimensional variations amount, that is, ovality It is very useful, but bearing ring outer diameter needs to measure at least three sections, the i.e. both ends of lasso and intermediate sizes, it is flat to determine Equal variation in diameter amount, that is, outer diameter taper.Following methods are generallyd use when using above-mentioned apparatus measures lasso average diameter variation:
1. when being measured on a D051 measuring apparatus of diameter, by being measured outside lasso both ends respectively on the basis of both ends of the surface Then diameter size increases by a gasket between one end face of lasso and locating platform, spacer height is the half of lasso height, so as to Lasso intermediate sizes are measured, and then obtain lasso outer diameter taper.
2. when being measured on two D051 measuring apparatus of diameter, wherein one is used to measure the both ends outer diameter of lasso, Another is used to measure lasso intermediate sizes, and then obtains outer diameter taper.
Since the requirement of bearing ring outer diameter is very strict, following ask usually there will be when measuring using above method Topic:
1. needing to increase point gasket when measuring intermediate sizes, but increase when measuring on a D051 measuring apparatus of diameter Measurement difficulty is not only increased after gasket, also produces bigger measurement error.
2. when using two D051 measuring apparatus of diameter measurements, since the different location of measurement Same Part is not in same instrument On device, and exist to Watch Error and measurement error, can not more really react lasso available accuracy.
3. the measurement of outer diameter small for flanged bearing, because the issuable outer diameter bus of processing method reason is not orthogonal to end Face, current measurement method can not be detected effectively.
