Description
Technical field
The utility model is related to core testing equipment technical field, especially relates to a kind of core test measuring device.
Background technology
O-shaped ball valve is the sizable valve of present control valve field occupancy volume, and its core is that whole valve is the most key
One part, so requirement on machining accuracy is very high, in core wherein as shown in Figure 1, A face and B identity distance from the size of the centre of sphere are also
One critical size, the height of its precision directly affects assembly qualified rate and the service life of valve.
Generally, the distance of this two identity distance centre ofs sphere all to ensure, measuring method typically has two kinds by indirect measurement：
First method, step 1, measures the size of sphere diameter；Step 2, measure the distance apart from end face for the core axle circular arc top；Step
Rapid 3, the distance away from end face for the core axle circular arc top, the size of as required guarantee are deducted with the radius of core.Second side
Method, step 1, measures the size in core runner hole；Step 2, measure the size in end face distance core runner hole；Step 3, two
The size that individual size ensures required for being added as.
But, two kinds of methods indirectly measuring have its drawback.As the measuring method of the first scheme, if core axle
Core circular arc car is fallen by top, and measuring process 2 cannot be realized, so cannot ensure end face with this kind of measuring method
Apart from the centre of sphere apart from dimensional accuracy.The measuring method of second scheme, if there is no guarantee that in car core end face end face with
The depth of parallelism in runner hole, being differently sized from the measurement of runner hole two ends in measuring process 2, so this kind of measuring method is not yet
Ensure well the distance of the end face distance centre of sphere.
Utility model content
The technical problems to be solved in the utility model is：There is asking of its drawback in order to solve above two measuring method
Topic, now provides a kind of core test measuring device.
The utility model solves its technical problem and be employed technical scheme comprise that：A kind of core test measuring device, including pedestal,
Main scale, slide block and dial gauge, described main scale has cross bar and montant, and one end of described montant is connected with pedestal, described montant
The other end is fixedly connected with described cross bar, and described cross bar is vertically arranged with described montant, and described slide block is slidably arranged in described horizontal stroke
On bar, described dial gauge is fixedly connected on described slide block, and the side of described cross bar is provided with main scale mark, the side of described slide block
Face is provided with subscale mark.It is close to the end face of core, the measurement end of dial gauge and the sphere-contact of core by pedestal, slide simultaneously
Movable slider, by observing the reading of inspection dial gauge, when the reading of dial gauge reaches maximum, then this position is that core end face is parallel
Centre of sphere section on, by count reference position, that is, the end face that contacts with core of pedestal to cross bar zero graduation line away from
From, and by being calculated the distance of the centre of sphere, can be protected with the distance of direct detection core end face to the centre of sphere by this measuring method
Demonstrate,prove accuracy of detection.
Testing staff determines reference position for convenience, facilitates testing staff's reading, further, described pedestal one end
End face is alignd with the zero graduation line on described cross bar.By the end contact of pedestal and core, on the basis of the end face of core, more
Plus facilitating testing staff's reading, the measurement end of dial gauge and the sphere-contact of core, sliding slider simultaneously, by observing test side
Reading, when the reading of dial gauge reaches maximum, then this position is on the parallel centre of sphere section of core end face, reads horizontal simultaneously
Reading on bar, the reading of reading is core end face to the distance of the centre of sphere.
In order that measurer facilitates reading in detection, further, in the measurement end of described dial gauge and described slide block
Zero graduation line aligns.By the measurement end of dial gauge is alignd with the zero graduation line on slide block, convenient staff's reading,
Improve detection efficiency.
In order that measurer also can facilitate reading after sensing, further, also include carrying on the back tight screw, described slide block passes through
Carry on the back tight screw to be fastened on described main scale.By carrying on the back tight screw, slide block is consolidated on cross bar, when light is poor, can will measure
Tool is taken well-lighted place and is carried out reading, facilitates staff to detect.
The beneficial effects of the utility model are：The utility model core test measuring device, when using, is close to ball by pedestal
The end face of core, the measurement end of dial gauge and the sphere-contact of core, sliding slider simultaneously, by observing the reading of inspection dial gauge,
When the reading of dial gauge reaches maximum, then this position is on the parallel centre of sphere section of core end face, by baseline position
Put, that is, the end face that contacts with core of pedestal is to the distance of cross bar zero graduation line, and by being calculated the distance of the centre of sphere, lead to
Crossing this measuring method can be with the distance of direct detection core end face to the centre of sphere it is ensured that accuracy of detection, and the utility model has inspection
Survey high precision, simple to operate, convenient reading, can direct measurement core end face to the centre of sphere distance.
