Abstract

A measuring device for the sealing surface of a flange relates to the measuring device for machine elements. The measuring device solves the problem that a machine tool needs to be used in the traditional measuring method. The measuring device is composed of inner hole supporting tubes, adjusting screw rods, bearing supports, conical roller bearings, center rods, measuring rods, sliders, a steel wire, spherical end sockets, leveling blocks and dial indicators, wherein the three leveling blocks are distributed along the periphery of the inner hole of the flange by 90 degrees; the long sides of the leveling blocks are clung to the inner hole of the flange; the short sides of the leveling blocks are clung to the sealing surface of the flange; the inner hole supporting tubes are T-shaped; the spherical end sockets are in contact with the three leveling blocks; adjusting screw rods are arranged in the three inner hole supporting tubes; the bearing supports are vertically fixed in the centre positions of the inner hole supporting tubes; the bearings are arranged between the bearing supports and the center rods; the measuring rods are vertically fixed at the upper parts of the center rods; and the sliders with the dial indicators are arranged on the measuring rods. The measuring device is used for measuring the sealing surface of the flange; the machine tool does not need to be used due to the adoption of the measuring device; the structure of the measuring device is reasonable in design; measuring data is accurate; and the measuring device is simple and convenient to operate.

Description

A kind of measurement mechanism of flange sealing surface
Technical field
The present invention relates to the measurement mechanism of mechanical component, particularly a kind of measurement mechanism of vessel flange sealing surface.
Background technology
Generally there are many nozzle flanges the periphery of tankage, and flange face has in use played the effect of sealing.And in manufacture process, welding and thermal treatment meeting make flange sealing surface cause distortion.If distortion surpasses certain limit, will influence the sealing effectiveness of flange sealing surface.At present, factory is that flange part is installed on the lathe in the measurement to flange sealing surface, rotates with dial gauge through lathe and measures, and need take lathe.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of measurement mechanism of flange sealing surface is provided, solve the problem that existing measuring method need take lathe.
The present invention realizes through following technical scheme.
A kind of measurement mechanism of flange sealing surface; It is characterized in that: said measurement mechanism is made up of endoporus stay pipe, adjustment screw mandrel, bearing bridge, taper roll bearing, center-pole, sounding rod, slide block, steel wire, spherical termination, leveling piece and dial gauge; Said leveling piece is the long limit square vertical with minor face; 3 said leveling pieces are close to the flange endoporus along the 90 degree distributions of flange endoporus circumference, long limit, and minor face is close on the flange sealing surface, and said endoporus stay pipe is " T " shape; 3 spherical terminations of said endoporus stay pipe contact with 3 said leveling pieces; Be provided with the adjustment screw mandrel in 3 said endoporus stay pipes, said endoporus stay pipe centre vertical fixing has bearing bridge, between said bearing bridge and its center-pole taper roll bearing is set; Said sounding rod is vertically fixed on said center-pole top, and the slide block that has dial gauge is installed on the said sounding rod.
Between said center-pole top and said sounding rod termination, strain with steel wire.
Adjustment bolt, set nut are set on the said leveling piece.
The present invention compared with prior art owing to utilized special tooling that flange sealing surface is measured, does not only take lathe, and because reasonable in design, measurement data is accurate, and is easy and simple to handle.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to view.
The present invention is elaborated through preferred embodiment below in conjunction with accompanying drawing.
Embodiment
Like Fig. 1, shown in 2; A kind of measurement mechanism of flange sealing surface; Be made up of endoporus stay pipe 1, adjustment screw mandrel 2, bearing bridge 3, taper roll bearing 4, center-pole 5, sounding rod 6, slide block 7, steel wire 8, spherical termination 9, leveling piece 10 and dial gauge 11, said leveling piece 10 is the long limit square vertical with minor face, and 3 said leveling pieces 10 are close to the flange endoporus along the 90 degree distributions of flange endoporus circumference, long limit; Minor face is close on the flange sealing surface; Said endoporus stay pipe 1 is " T " shape, and 3 spherical terminations 9 of said endoporus stay pipe 1 contact with 3 said leveling pieces 10, is provided with adjustment screw mandrel 2 in 3 said endoporus stay pipes 1; Said endoporus stay pipe 1 centre vertical fixing has bearing bridge 3; Between said bearing bridge 3 and its center-pole 5 taper roll bearing 4 is set, said sounding rod 6 is vertically fixed on said center-pole 5 tops, and the slide block 7 that has dial gauge 11 is installed on the said sounding rod 6.
Between said center-pole 5 tops and said sounding rod 6 terminations, strain with steel wire 8.
Adjustment bolt 10-1, set nut 10-2 are set on the said leveling piece 10.
Endoporus stay pipe 1 has 3 supports, guarantees stable being supported in the flange endoporus of survey instrument ability; Endoporus stay pipe 1 middle part is a bearing bridge 3, and bearing bridge is vertical with the endoporus support bar.Bearing 4 adopts taper roll bearings, leans on last lower flange regulating shaft to hold the gap, guarantees that center-pole 5 can smooth-goingly rotate, and does not exist radially again, end play.Sounding rod 6 is fixed on the center-pole 5 and vertical and center-pole, for preventing sounding rod vibration in the use, holds with steel wire 8, during the instrument calibration steel wire 8 is regulated.Adjustment bolt 10-1, set nut 10-2 are set on the leveling piece 10, and the adjustment bolt is also used nut lock during calibration, does not allow loosening set nut during measurement.
The principle of work of the present invention and the course of work:
At first measurement mechanism will be calibrated on standard flange, guarantees 3 the adjustment pieces 10 and sounding rod 6 surfaces of revolution on same plane, and the calibration back just can have been measured flange sealing surface.With the flange horizontal positioned, be installed in measurement mechanism in the flange endoporus that needs to measure, regulate adjustment screw mandrel 2,3 leveling pieces 10 are all withstood in the flange endoporus, the adjustment bolt 10-1 on the leveling piece 10 all is fitted on the flange sealing surface.Moving slider 7 is contained in dial gauge 11 on the slide block 7 to the flange sealing surface place, locking slide block 7.Adjustment dial gauge 11 makes pointer to zero.360 ° of wheel measuring bars 6 are observed dial gauge 11 readings and record.Can draw the deformation data of flange sealing surface to the interpretation of records analysis.
