Abstract
The invention discloses a kind of measuring methods of steel pipe kerve Edge Distance, before measurement, first measure a calibrated bolck, calibrated bolck are placed on the V-groove of V-block, and is limited up and down, vertical lines guide rail moves down H distances, and obtains image above calibrated bolck and record；Tested steel pipe is replaced, first tested steel pipe is placed on V-block, selects one kind of different-diameter steel pipe, V-block is moved by lateral the linear guide, so that the center of steel pipe and the central coaxial of measuring apparatus, move vertical lines guide rail again at this time, kerve image above tested steel pipe is acquired；With calibrated bolck image comparison, if difference is Ho up and down for two images, then tested distance of the kerve apart from end face is exactly H+Ho.The advantage of the invention is that：Part is inserted into measuring apparatus lead by the measuring system, easy to operate simple, raising efficiency, the error that reduction personnel's measurement is brought, and in detection process, does not damage inner wall of cylinder.
Description
Technical field
The present invention relates to technology of instrument and meter field, more particularly to a kind of measuring method of steel pipe kerve Edge Distance.
Background technology
A kind of existing steel pipe, there are one kerves on inner wall, need to measure kerve to the distance of steel pipe end surface, present side
Method：Steel pipe is splitted, kerve is directly measured with slide calliper rule to the distance of end face.Efficiency is low, and part is all scrapped, and measurement accuracy
It is low.To solve the above-mentioned problems, the present inventor designs a kind of measuring method of steel pipe kerve Edge Distance.
Invention content
The technical problem to be solved in the present invention is to provide a kind of steel pipe kerves that can improve measurement accuracy and measurement efficiency
The measuring method of Edge Distance.
In order to solve the above technical problems, the technical scheme is that：A kind of measuring method of steel pipe kerve Edge Distance,
Its innovative point is：Including measurement standard block, tested steel pipe and calculating steel pipe kerve Edge Distance are measured, is as follows：
（1）Measurement standard block：
Before measurement, a calibrated bolck is first measured, calibrated bolck is placed on the V-groove of V-block, and is limited up and down, vertical lines
Guide rail moves down H distances, and obtains image above calibrated bolck and record；
（2）Measure tested steel pipe：
Tested steel pipe is replaced, first tested steel pipe is placed on V-block, selects one kind of different-diameter steel pipe, by laterally straight
Line guide rail moves V-block so that the center of steel pipe and the central coaxial of measuring apparatus move vertical lines guide rail, adopt again at this time
Kerve image above the tested steel pipe of collection；
（3）Calculate steel pipe kerve Edge Distance：
Kerve image and calibrated bolck image comparison above tested steel pipe, if difference is Ho to two images up and down, then tested to draw
The distance of slot distance end face is exactly H+Ho.
Further, steel pipe pull-up groove edge position is shown in the optical system of measuring system, the reflection of measuring apparatus
The location drawing picture of kerve is transferred to camera by mirror, according to the principle of image procossing, then image magnification, is shown by display
Come.
The advantage of the invention is that：
（1）Part is inserted into measuring apparatus lead by the measuring system, easy to operate simple, improves efficiency, is reduced personnel and is measured
The error brought realizes full-automatic non-contact detection, and by image procossing, AD conversion, data calculate, directly on the screen
Show specific distance value；In detection process, inner wall of cylinder is not damaged.
（2）Measuring apparatus, which does not need to change, is oriented to column diameter, as long as the outer diameter of lead is less than the internal diameter of minimum steel pipe
, outer diameter and length can be arbitrary dimension.
（3）By changing speculum axial position, part of the kerve apart from aperture any position can be measured.
（4）Each series is equipped with 1 master body and is calibrated for tooling, the position that the positioning of configuration calibration block is placed in cubing,
In order to avoid calibration lost block.
Specific embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
A kind of measuring method of steel pipe kerve Edge Distance including measurement standard block, measures tested steel pipe and calculating steel pipe
Kerve Edge Distance, is as follows：
（1）Measurement standard block：
Before measurement, a calibrated bolck is first measured, calibrated bolck is placed on the V-groove of V-block, and is limited up and down, vertical lines
Guide rail moves down H distances, and obtains image above calibrated bolck and record；
（2）Measure tested steel pipe：
Tested steel pipe is replaced, first tested steel pipe is placed on V-block, selects one kind of different-diameter steel pipe, by laterally straight
Line guide rail moves V-block so that the center of steel pipe and the central coaxial of measuring apparatus move vertical lines guide rail, adopt again at this time
Kerve image above the tested steel pipe of collection；
（3）Calculate steel pipe kerve Edge Distance：
Kerve image and calibrated bolck image comparison above tested steel pipe, if difference is Ho to two images up and down, then tested to draw
The distance of slot distance end face is exactly H+Ho.
When measurement standard block and tested steel pipe, steel pipe pull-up groove edge position is shown in the optical system of measuring system,
The location drawing picture of kerve is transferred to camera by the speculum of measuring apparatus, according to the principle of image procossing, then image magnification, is led to
Display is crossed to show.
Basic principle of the invention and main feature and advantages of the present invention has been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
