Abstract
Disclosed is a detecting sample of a bearing raceway position, which is composed of sample bodies 1, curvature disks 2, measuring arms 3, screw nails 4 and height blocks 5. The detecting method is that a height block valued Lmax (or called the large range of the sample) is located between the curvature disk and the sample body, which is subject to that the height block doesn't drop off, then, the screw nails of the measuring arm and the sample is fastened, another height block valued Lmin (or called the small range of the sample plate) is located between the curvature disk and the sample body which are located at another side, which is subject to that the height block doesn't drop off, similarly, the screw nail of another measuring arm and another sample, thereby the sample of combined raceway position can be used. When using, the sample body is abutted against the end surface of the benchmark of the bearing parts, when using the large range of the sample plate to measure, the sample body should be abutted against the seam of the benchmark surface of the parts, when using the small range of the sample to measure, the sample should be abutted against the seam of the benchmark surface of the parts, thereby changing the fixing sample of the raceway position to a combine sample which is movable and demountable, and not changing the design principle of the origin sample of the raceway position.
Description
Technical field
The invention belongs to bearing detection technique field, specially refer to a kind of raceway method for detecting position and detect model.
Background technology
In Production of bearing processing, the raceway processing of bearing is an indispensable procedure, add the position that to measure raceway man-hour at raceway, usually use fixing raceway position model to measure raceway position, the raceway position model is processed more complicated, and the cycle is long, and general manufacturer is difficult for accomplishing, and the cost height, some special raceway position sample need possess the secondary instrument and the professional just can process.Particularly change or raceway position when changing when the radius-of-curvature of raceway, the raceway position model just can not use, and needs making again, tends to delay production.
Summary of the invention
At above-mentioned defective, the purpose of this invention is to provide a kind of raceway method for detecting position and detect model, to overcome the model difficult processing, the shortcoming that the cycle is long is increased work efficiency effectively.
In order to realize the foregoing invention purpose, the present invention adopts following technical scheme:
Described raceway method for detecting position, choose suitable height piece according to Lmax and Lmin value, with value is the height piece of Lmax or the centre that the big model of title model is placed on curvature disk and model body, does not fall down with the height piece to be as the criterion, and tightens the screw of gage beam and model body then; With another piece value height piece that is Lmin or claim the little model of model to be placed on the centre of the curvature disk and the model body of another side, do not fall down with the height piece and be as the criterion, tighten the screw of another gage beam and model body equally, combination raceway position model just can use; With the datum end face of model body near bearing parts, when measuring with the big model of model, should be to stitch thoroughly by the part reference field during use, when measuring with the little model of model, should be to stitch thoroughly by the non-reference field of part; So fixing raceway position model is changed into movable dismountable combination model, do not change the design concept of original raceway groove position model.
Described raceway method for detecting position, the value of two height piece Lmax and Lmin is as follows:
Lmax＝Hmax-Rmin
Lmin＝Hmin-Rmin
Hmax=H+ Δ H in the formula, Hmin=H-Δ H; H is that raceway position nominal value, Δ H are that raceway position deviate, Rmin are the minimum limit value of raceway radius-of-curvature.
Described raceway position probing model is made up of model body, curvature disk, gage beam, screw and height piece, wherein the curvature disk is by the elbow end of screw retention at gage beam, two gage beams are separately fixed on the model body by screw, and the spacing between two gage beams is determined by different height pieces; Curvature disk top on one gage beam limits apart from the height piece of model body edge value by Lmax, and the curvature disk top on another gage beam limits apart from the height piece of model body edge value by Lmin.
Owing to adopt technical scheme as mentioned above, the present invention has following superiority:
1, this measuring method greatly facilitates the inspection work of raceway position, and the raceway position model is become simply by complexity, and each processing curvature disk that only needs has improved work efficiency effectively, has reduced cost.Be particularly suitable for the manufacturer that bearing species is many, quantity is few.
2, it is simple to operate that this raceway position detects model, and sensing range is wide, and lengthening model body can be checked the raceway position of larger size range, different model specification.Raceway position is an important control project in the Production of bearing industry, and therefore making up the raceway position model seems particularly important, can produce good economic benefit.
3, this raceway position detect model have easy to process, efficient is high, effect such as easy to use.

Embodiment
Raceway method for detecting position of the present invention, choose suitable height piece according to Lmax and Lmin value, with value is the height piece of Lmax or the centre that the big model of title model is placed on curvature disk and model body, does not fall down with the height piece to be as the criterion, and tightens the screw of gage beam and model body then; With another piece value height piece that is Lmin or claim the little model of model to be placed on the centre of the curvature disk and the model body of another side, do not fall down with the height piece and be as the criterion, tighten the screw of another gage beam and model body equally, combination raceway position model just can use; With the datum end face of model body near bearing parts, when measuring with the big model of model, should be to stitch thoroughly by the part reference field during use, when measuring with the little model of model, should be to stitch thoroughly by the non-reference field of part; So fixing raceway position model is changed into movable dismountable combination model, do not change the design concept of original raceway groove position model.
: raceway position probing model is made up of model body 1, curvature disk 2, gage beam 3, screw 4 and height piece 5 as shown in Figure 1, 2, wherein curvature disk 2 is fixed on the elbow end of gage beam 3 by screw 4, two gage beams 3 are separately fixed on the model body 1 by screw 4, and the spacing between two gage beams 3 is determined by different height piece 5; Curvature disk 2 tops on one gage beam 3 limit apart from the height piece 5 of model body 1 edge value by Lmax, and curvature disk 2 tops on another gage beam 3 limit apart from the height piece 5 of model body 1 edge value by Lmin.The value of two height piece Lmax and Lmin is as follows:
Lmax＝Hmax-Rmin?Lmin＝Hmin-Rmin
Hmax=H+ Δ H in the formula, Hmin=H-Δ H; H is that raceway position nominal value, Δ H are that raceway position deviate, Rmin are the minimum limit value of raceway radius-of-curvature.
The present invention changes fixing raceway position model into movable dismountable, do suitable adjustment according to the size of the radius-of-curvature of raceway and the variation of raceway position, both solved processing problems, saved cost again, do not need integral manufacturing again even processing technology has changed yet, only need processing part part again.This improved application does not change the design concept of original raceway groove position model, just fixing raceway position model is decomposed and makes the combination model, has just solved problem.
