Abstract
A precise detecting instrument for a bearing ring comprises a five-pass joint, five measuring bars and a dial indicator. Five ports of the five-pass joint are in screw connection with the five measuring bars respectively, and the five measuring bars comprise a first measuring bar, a second measuring bar, a third measuring bar, a fourth measuring bar and a fifth measuring bar respectively. The dial indicator is fixed on the first measuring bar through a fastener. A support component is fixed on the second measuring bar through a fastener. The support component comprises a support and a measuring bearing bar which is arranged in a groove of the support, and the support and the measuring bearing bar are located through a nut arranged in a kidney-shaped hole. A support component is fixed on the third measuring bar through a fastener. A fastener is fixed on the fourth measuring bar. By means of the precise detecting instrument, the defect of the incapability to guarantee that the whole section plane is measured precisely can be overcome, and measuring results are accurate and stable. In a utilization process of the detecting instrument, the bearing ring is fixed, the instrument is rotated, measurement resistance caused by abrasion between the bearing ring and the instrument plane is reduced, and the stability of the measuring result is guaranteed.
Description
Technical field
The utility model belongs to bearing detection technique field, and particularly a kind of precision bearing lasso detecting instrument, can be applicable to the large-scale precision bearing collar precision and detect.
Background technology
Present bearing ring accuracy detection, mainly depend on the conventional bearing testers of special production bearing testers device manufacturer production, the measurement range great majority of the conventional domestic present maximum of bearing testers are that external diameter is less than 500mm, and for the precision bearing of external diameter greater than 500mm, also there is no special detecting instrument.Most bearings manufacturing enterprise mainly carries out rough measure, Measurement sensibility, poor accuracy with pipe chi, aligner etc.And have the part test item to measure, for example, end face is beated and the main projects such as prismatic roundness of interior outer fissure to endoporus.Can't measure after bearing ring processing, not guarantee the precision stability of bearing ring.The precision of lasso can not be guaranteed, and will directly affect the precision of complete bearing, and then affects the overall precision of corresponding plant equipment.Existing domestic detecting instrument is not suitable for the detection of large-scale precision bearing.
The utility model content
The purpose of this utility model is to provide a kind of precision bearing lasso detecting instrument, and three end face Pivot Distributions of this instrument are on same circumference, and measurement result is accurate, stable.
The technical scheme that adopts is:
A kind of precision bearing lasso detecting instrument comprises five-way joint, five sounding rods and clock gauge.
Its technical essential is:
Five interfaces of five-way joint are bolted with respectively five sounding rods, and described five sounding rods are respectively the first sounding rod, the second sounding rod, the 3rd sounding rod, the 4th sounding rod and the 5th sounding rod.
Fixedly be equiped with clock gauge by clamp on the first sounding rod.
Be fixed with mounting assembly by clamp on the second sounding rod.Described mounting assembly comprises bearing and measures push rod, measures push rod and is installed in the groove of bearing, locates by the nut that is installed in mounting hole between bearing and measurement push rod.
Be fixed with mounting assembly by clamp on the 3rd sounding rod.The 4th sounding rod is fixed with clamp.
This instrument can carry out accuracy detection to the large-scale precision bearing lasso, and this instrument can carry out to the bearing ring of external diameter 400mm～1600mm the accuracy detection of full phase.
This detecting instrument, with the datum end face of tested lasso up, three end face Pivot Distributions of instrument are on same circumference, and radial location is adjusted by two positioning supporting points of instrument.By adjusting the angle of positioning supporting point and measurement point, can realize the detection of disparity items, lasso is fixed in measuring process simultaneously, the overlooker the instrument rotation with hand push, because end face adopts supported at three point, so when measuring, frictional resistance is very little, measurement result is accurate, stable.
Its advantage is:
The contrast of this instrument has very large superiority with measuring methods such as pipe chi, aligners, adopted pipe chi, aligner measurement is to get point measurement in the past, can not guarantee that whole cutting plane all measures, this instrument can overcome above shortcoming, and measurement result is accurate, stable.
In the use procedure of this instrument, lasso is fixed, and the instrument rotation has reduced the measurement resistance that is produced by lasso and instrument planar friction, has guaranteed the stability of measurement result.
This instrument can be adjusted according to the difference of test item angle and the position of two positioning supporting points and measurement point, in testing process, lasso is motionless, the instrument rotation can realize that whole measurement of cutting plane puts in place, thereby completes the detection of the precision such as bearing ring size, ellipse, tapering, prismatic roundness, ditch pendulum, verticality.

Fig. 2 is the A section partial enlarged drawing in Fig. 1.
Embodiment
A kind of precision bearing lasso detecting instrument comprises five-way joint 6, five sounding rods and clock gauge 7.
Five interfaces of five-way joint 6 are bolted with respectively five sounding rods, and described five sounding rods are respectively the first sounding rod 1, the second sounding rod 2, the 3rd sounding rod 3, the 4th sounding rod 4 and the 5th sounding rod 5.
Fixedly be equiped with clock gauge 7 by clamp on the first sounding rod 1.
Be fixed with mounting assembly 11 by clamp on the second sounding rod 2.Described mounting assembly 11 comprises bearing 8 and measures push rod 9, measures push rod 9 and is installed in the groove of bearing 8, locates by the nut 10 that is installed in mounting hole between bearing 8 and measurement push rod 9.
Be fixed with mounting assembly 11 by clamp on the 3rd sounding rod 3.The 4th sounding rod 4 is fixed with clamp.
Between described the first sounding rod 1 and the second sounding rod 2, angle is 90 degree, and between the second sounding rod 2 and the 3rd sounding rod 3, angle is 60 degree.
Using method is:
Angle that can be by adjusting two positioning supporting points and measurement point or position are completed complete of bearing ring 12 precision and are detected, and in measuring process, bearing ring 12 is fixing, and the checker promotes the instruments rotation by the 5th sounding rod 5.
