Description
Technical field
The invention belongs to measuring equipment and measuring method, relate to a kind of measurement mechanism and measuring method of bearing washer inner arc surface.
Background technology
External centre-adjusting thrust ball bearing belongs to the one of thrust ball bearing, and unidirectional external centre-adjusting thrust ball bearing can bear unidirectional axial load, and two-way external centre-adjusting thrust ball bearing can bear bi-directional axial load.Can in production run, the Measurement accuracy of the packing ring arc size of external centre-adjusting thrust ball bearing be an industry difficult problem always, and whether the accuracy of measurement is related to product qualified, thus affect product and assemble and use.
Detection method is in the past, because arc surface is made up of numerous circle, can not measure one by one, so select two circles of specified diameter as measurement point on arc surface, such as diameter is two circles of 23 and 26 millimeters, measure the height dimension of these two circles, but be difficult to determine that diameter is the position of 23 and 26 millimeters of two circles on circular arc, be also just difficult to measure accurately required height dimension.Diameter is the position of 23 and 26 millimeters of two circles and height dimension is by calculating one to one, and circle all above circular arc all one_to_one corresponding a height dimension, and two selected circles are two representative circles.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of structure measurement mechanism that is simple, easy to use, bearing washer inner arc surface accurately and reliably and measuring method.
The present invention is achieved through the following technical solutions:
The measurement mechanism of bearing washer inner arc surface of the present invention, its special character is: comprise support, the curvature standard steel ball identical with bearing washer inner arc surface and measuring point is faceted dial test indicator, support comprising flat table platform for placing bearing washer, being upwards arranged on the vertical rod on flat table platform and being arranged on the cross bar on vertical rod top, and dial test indicator is arranged on cross bar.
Preferred version is, with the standard steel ball Measurement accuracy bearing washer inner arc surface height dimension lacking a part.Standard steel ball bottom surface lacks a part, avoids contact plane table platform below standard steel ball.
The measuring method of bearing washer inner arc surface of the present invention, its special character is: comprise the following steps:
(1) bearing washer is placed on flat table platform;
(2) contact completely inside inner arc surface standard steel ball being placed on bearing washer, allow the part that lacks of standard steel ball avoid contact plane table platform below;
(3) dial test indicator is arranged on cross bar, and dial test indicator and standard steel ball contact portion are a facet, and dial test indicator contact, at the peak of standard steel ball, records the reading of dial test indicator; This reading represents that in margin tolerance between the Inner arc of this bearing washer and lower plane, height dimension is qualified.
The invention has the beneficial effects as follows, structure is simple, easy to use, accurately and reliably, by contacting completely of standard steel ball and bearing washer Inner arc, utilize the facet with the dial test indicator measurement point of standard steel ball tip contact, read the reading of dial test indicator, and contrast with standard-required, judge that whether bearing washer inner arc surface qualified, like this can Measurement accuracy normal method be difficult to measure bearing washer inner arc surface and lower plane between height dimension whether qualified.
Accompanying drawing explanation
Fig. 1 is use schematic diagram of the present invention.
In figure, 01: standard steel ball, 02: bearing washer, 03: flat table platform, 04: dial test indicator, 05: cross bar, 06: vertical rod.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
The measurement mechanism of bearing washer inner arc surface of the present invention, comprise support, bearing washer 02, the curvature standard steel ball 01 identical with bearing washer inner arc surface and measuring point is faceted dial test indicator 04, support comprising flat table platform 03 for placing bearing washer, being upwards arranged on the vertical rod 06 on flat table platform and being arranged on the cross bar 05 on vertical rod top, and dial test indicator 04 is arranged on cross bar.With the standard steel ball Measurement accuracy bearing washer inner arc surface height dimension lacking a part.Standard steel ball bottom surface lacks a part, avoids contact plane table platform below standard steel ball.
The measuring method of bearing washer inner arc surface of the present invention, comprises the following steps:
When 1, measuring, bearing washer 02 is placed on flat table platform 03;
2, contact completely inside inner arc surface standard steel ball 01 identical with bearing washer circular arc for curvature being placed on bearing washer 02, allow standard steel ball 01 lack part and avoid contact plane table platform below;
3, dial test indicator 04 is arranged on cross bar 05, dial test indicator and standard steel ball 01 contact portion are a facet, dial test indicator contact is at the peak of standard steel ball, can make to guarantee during measurement to measure the peak at standard steel ball, the reading of record dial test indicator; Between the Inner arc of this bearing washer of expression of this reading in margin tolerance and lower plane, height dimension is qualified.
4, standard steel ball and bearing washer is taken off, according to the reading of dial test indicator corresponding to above other bearing washer of step survey record.
First the distance X from bearing washer lower plane to steel ball top is calculated during measurement, dial test indicator 04 is arranged on cross bar 05, dial test indicator and standard steel ball 01 contact portion are a facet, with the gauge block his-and-hers watches equally high with result of calculation, generalized case is to 0 scale by the reading of table, directly can measure the height at bearing washer Inner arc place like this, solve the problem that bearing washer crown height size is difficult to Measurement accuracy.
This project is a kind of external centre-adjusting thrust ball bearing measuring method, and survey instrument is that faceted dial test indicator 04 6 major part forms by flat table platform 03, vertical rod 06, cross bar 05, bearing washer 02, standard steel ball 01 that curvature is identical with bearing washer circular arc, measuring point.By contacting completely of standard steel ball and bearing washer circular arc, utilize the facet with the dial test indicator measurement point of standard steel ball tip contact, can the Measurement accuracy normal method size of bearing washer inner arc surface that is difficult to measure whether qualified, namely whether the round place height of all diameters of inner arc surface qualified.
This detection method is that standard steel ball and arc surface fit like a glove, such as diameter is two circles of 23 and 26 millimeters, their place height can be calculated by theoretical value, and the theoretical value of the overall height dimension X of steel ball and bearing washer is that the height of the circle of 23 and 26 millimeters and two diameter of a circles of regulation calculate by diameter.When therefore measuring, if size X meets the requirements, the height dimension of two circles of regulation just necessarily meets the requirements.
