Description

The measurement mechanism of a kind of bearing seal groove position

[technical field]

The utility model relates to bearing and makes the field, is specifically related to the measurement mechanism of a kind of bearing seal groove position.

[background technology]

Known, bearing has been widely applied in all trades and professions, in the process of bearing, for the quality that guarantees bearing reaches designing requirement, often to measure the relative dimensions of processing rear bearing, wherein survey crew is when measuring the seal groove on the bearing ring, usually the method that adopts is " to be defined as φ Dx; hereinafter to be referred as φ Dx " to survey highly " being defined as height h, hereinafter to be referred as height h " on the diameter that the bearing seal groove angle conical surface " is defined as the β angle; hereinafter to be referred as the β angle "; The measuring method that present those skilled in the art use always mainly contains following several:

First kind of measuring method is the test desk method: at first at the special-purpose stepped test desk of model processing of measuring bearing, below the test desk lower step, be provided with the conical surface that matches with bearing ring seal groove pyramidal plane, its conical surface angle equals the β angle, the height of the lower step of test desk is ho, external diameter equals φ Dx, secondly after test desk being placed the surface of seal groove conical surface φ Dx of bearing ring, the assembly of bearing ring and test desk is placed on the substrate of altimeter, steadily pushing away its assembly places under the gauge head of height survey table assembly, gauge head points on the metering face of test desk " be test desk lower step top on ", survey this moment table shows apparent size and is designated as hx, so the hx=h+ho that records is measurement target size h=hx-ho; Use the shortcoming of this kind survey method to be: the test desk manufacturing accuracy requires height, calibrating difficulty and manufacturing cost height; Simultaneously since test desk from great, and then big, the inefficiency of labour intensity when causing measuring operation, operating personnel easily cause the bump injury of test desk and bearing ring and the measurement misalignment that causes in measuring process; Because the conical surface of measured bearing lasso is Vehicle Processing, and then causes the stickiness of the bearing ring seal groove conical surface and the test desk conical surface poor, measuring accuracy is reduced, main is because the measurement of this kind method is not direct measurement, and then causes measuring error increase etc.

Second kind of measuring method is limit model mensuration: at first design and manufacture the measurement model by detecting requirement, a side of measuring model is big model, side is little model in addition, when big model can be fallen at the end, when little model fell not on earth, then workpiece was qualified, this kind survey method can only qualitatively judge with vision and sense of touch, the precision that detects is lower, and is strict to testing staff's technical ability, can't use this method to measure at the higher workpiece of accuracy requirement.

The third measuring method is that contourgraph is surveyed method: at first tested bearing ring is placed on the substrate of contourgraph, adjust to survey and pick up head, then from basal plane to impact point, the measurement result intelligent digital, the measuring accuracy of above-mentioned metering system is determined by the quality of machine, its precision of machine at different brands is widely different, at the high machine of some precision, acquisition expenses is very expensive, and most of brand is technical still immature, only be suitable for the laboratory at present, should not be used for the batch check of workplace.

[summary of the invention]

[embodiment]

Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples;

The measurement mechanism of 1～4 described a kind of bearing seal groove position by reference to the accompanying drawings, comprise altimeter, meter 6 and location fork 10, side in substrate 5 upper side of altimeter is provided with vertical rod 4, the altimeter model is G904, the top movable of described vertical rod 4 is provided with slide block 3, described slide block 3 connects an end of cross bar 2, the other end at described cross bar 2 is provided with meter 6 by latch segment 1, described meter 6 is clock gauge, any side in substrate 5 upper side is provided with the measurement mechanism that V-shape location fork 10 forms described bearing seal groove position, angle between fork 10 both sides, described V-shape location is 120o, and the shape that the shape of described location fork 10 is set to have positioning function all can.

The measuring method of a kind of bearing seal groove position, described measuring method comprises the steps:

The first step: processing gauge block 7, related request according to bearing ring 8 during processing gauge block 7 designs, makes, detects gauge block 7, mark at the metering face place of gauge block 7 " namely making mark at the diameter place that is equal to bearing seal groove 9 pyramidal planes " with colouring then, mark the metering detection zone simultaneously;

Second step: his-and-hers watches, at first will locate fork 10 is fixed on the substrate 5, pitched 10 o'clock in stationary positioned, at first gauge block 7 is placed in the angle that fork 10 both sides in location form, gliding by slide block 3 drives meters 6 and descends, and makes the gauge head of meter 6 vertically refer to center in the metering face mark of gauge block 7, locking positioning fork 10, rotate gauge block 7 then gently, the gauge head of meter 6 is placed in the metering detection zone, reference point, his-and-hers watches point and qualified district are set in the card of meter 6 in the back as calculated;

The 3rd step: measure, after 6 pairs of meters are got well, with the handle of carrying that has pulled meter 6 tops, make on meter 6 gauge heads and move, take out gauge block 7, further bearing ring 8 is placed in the angle of location fork 10 both sides formation, and determine that the location is correct, the handle of carrying that puts down meter 6 tops this moment points on the measured point of bearing ring 8 its gauge head vertical, numerical value is the size of required measurement shown at this moment on meter 6 dial plates, behind the record that record data and process comparison step 2 are done, with the handle of carrying on portable meter 6 tops, move on the gauge head of meter 6, take out bearing ring 8 and namely finished one-shot measurement this moment.

The utility model is in implementation process, and influencing factors of accuracy has the following aspects:

1, the outside diameter tolerance Δ D of bearing ring 8;

2, the deviations of φ Dx.

Height about precision: do not consider φ Dx deviation, when measuring point on the middle separated time of 120 ° of location forks 10, outside diameter tolerance Δ D, this moment precision minimum=(Δ D*tg β)/2; When measuring point is on 30 ° of lines, outside diameter tolerance Δ D, this moment precision the highest=(Δ D*cos30 ° of * tg β)/2;

The case precision=(0.05*tg9 °)/2=0.004(is minimum)

The case precision=(0.05*cos30 ° * tg9 °)/2=0.003(is the highest)

In order to eliminate φ Dx deviation effects precision, when his-and-hers watches are located, adopt to " in ", put into practice confirmation through us, with synthesis precision≤0.008 of this method detection cylindrical 52≤D 〉=315 o'clock.

The utility model is not limited to the bearing manufacture field in implementation process, also can be used in the mechanical industry measurement at similar products.

The utility model does not describe part in detail and is prior art.

The embodiment that selects for use in this article for open the purpose of this utility model currently thinks to suit, and still, will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the interior embodiment of this design and invention scope.
