Description
Technical field
The present invention relates to the machining field of pipeline valve, the rapid measurement device of specifically a kind of components symmetry.
Background technique
In the high pressures such as petroleum pipeline, the pipeline field of high temperature, the both ends of the surface of the valve seat orifice of valve body and middle flange hole need pole
High symmetry is just able to satisfy the sealing performance of valve, and the open and close that the sealing performance of valve is directly related to valve are turned round
The size of square.In the quality check process to valve valve seat orifice, measurement difficulty has two o'clock: 1, body cavity narrow space, general
Measuring device can not protrude into；2, middle flange hole diameter tolerance is big, can not cannot accurately measure symmetry as direct datum level.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, a kind of pair that can extend into inside parts small space is provided
Title degree measuring device.
In order to achieve the above object, the present invention is implemented as follows:
A kind of rapid measurement device of components symmetry, including bracket, magnet, lock screw and amesdial；Wherein, bracket is
Magnet is arranged in bottom end, that is, horizontal ends end of the support arm of one L shape, the bracket, and top, that is, vertical end end is opened
The probe in hole, amesdial is inserted into the aperture of cantilever tip, and the side of cantilever tip aperture is provided with lock screw, passes through
It fastens the lock screw and fastens amesdial.
The application method of the rapid measurement device, including
Rapid measurement device described in claim 1 is adsorbed on by the magnet of its bracket bottom end and puts valve seat orifice by step 1
On end face；
The telescopic head of amesdial is touched on middle flange aperture and moves left and right entire measuring device to find most by step 2
High point records numerical value；
Measuring device is removed and repeats to operate in the valve seat orifice of the other side by step 1, the sequence of step 2 by step 3；
Step 4 compares measurement result twice and calculates symmetry error numerical value.
Small in size, light weight of this measuring device, convenient for being operated in the small space inside components.Meanwhile this survey
It measures device and its measurement method to carry out using datum coincidence principle, and middle flange diameter size and tolerance values all will not influence
Symmetry detection accuracy, therefore this measuring device and measuring method also has measurement accuracy high, versatile, easy to use
The characteristics of, it can reflect symmetrical angle value to quicklook, have the characteristics that manufacturing cost is low, measurement effect is good.

Amesdial 4；Wherein, bracket 1 is the support arm of a L shape, and magnet 2 is arranged in bottom end, that is, horizontal ends end of the bracket 1,
The end aperture of top, that is, vertical end, the probe of amesdial 4 are inserted into the aperture on 1 top of bracket, in 1 top aperture of bracket
Side is provided with lock screw 3, is fastened amesdial 4 and fastening lock screw 3.
As shown in Fig. 2, the application method of the rapid measurement device, including
Rapid measurement device described in claim 1 is adsorbed on valve seat orifice 5 by the magnet 2 of its 1 bottom end of bracket by step 1
End face on；
The telescopic head of amesdial 4 is touched on middle flange aperture and moves left and right entire measuring device to find most by step 2
High point records numerical value；
Measuring device is removed and repeats to operate in other side valve seat orifice 5 by step 1, the sequence of step 2 by step 3；
Step 4 compares measurement result twice and calculates symmetry error numerical value.
Small in size, light weight of this measuring device, convenient for being operated in the small space inside components.Meanwhile this survey
It measures device and its measurement method to carry out using datum coincidence principle, and middle flange diameter size and tolerance values all will not influence
Symmetry detection accuracy, therefore this measuring device and measuring method also has measurement accuracy high, versatile, easy to use
The characteristics of, it can reflect symmetrical angle value to quicklook, have the characteristics that manufacturing cost is low, measurement effect is good.
