Description
Technical field
Survey tool, particularly a kind of combined type weld seam are examined the present invention relates to pipeline and end socket product groove angle
Inspection of groove chi.
Background technology
At present in the manufacture processing of pipeline and end socket product, welding is most common processing technology, generally to welding
In the case that joint quality has higher requirements, in such as pressure pipeline, pressure vessel, the manufacture of boiler product, often relate to big
Require to do welding position in advance groove processing in the pressure parts such as bore, wall thickness part, welding procedure, such as pipeline, end socket treats toe
Edge, to ensure that can be related to groove in welding quality, welding procedure opens up and examine.Current most domestic manufacturer uses
The groove that Numerical control cutting carries out tubing is opened up, and automatic cutting bevelling is also used sometimes, but no matter which kind of cutting form is used, and is all needed
Bevel angle after cutting is tested, by bevel angle control in certain deviation range, to ensure welding quality.Mesh
It is preceding when carrying out bevel cut angle to the edge of large diameter pipeline, end socket and examining, the most frequently used instrument of Field Force is welding
Detection ruler, can be used for detecting the angle of welding groove and weld high, it detects that data are more accurate.
According to GB/T25198-2010《Pressure vessel head》, the most frequently used butting grooves angle of end socket is 30 °, and it is permitted
Perhaps deviation is ± 3 °.According to GB986-2008《The citation form and size of submerged-arc welding welding line groove》, pipe fitting is the most frequently used
Butting grooves angle have 60 °, 45 °, its allow deviation be ± 5 °.
As shown in Figure 1, the frontal left of main scale 1 be with a scale 2 secondary ruler 3, the positive right side of face of main scale 1 be provided with can on move down
Dynamic undercut depth measuring ruler 4, the side of undercut depth measuring ruler 4 and the correspondence position of main scale 1 contrast scale 5 with undercut, sting
The lower end of side depth measuring ruler 4 is installed with probe 6, and the lower end of main scale 1 has level to keep to the side 7, by the way that level is kept to the side 7 to be close to workpiece
Surface, undercut depth value can be detected by moving down probe 6 and compareing undercut contrast scale 5；The positive Middle face of main scale 1 is provided with energy
The multi-purpose stock rod 8 moved up and down, the side and the correspondence position of main scale 1 for using stock rod 8 contrasts scale 9 with groove, uses stock rod 8
Lower end be 60 ° of butting grooves test sides 10, it is 50 ° of butting grooves test sides 11 to use the upper end of stock rod 8.By observing 60 °
The gap and groove contrast scale 9 that butting grooves test side 10,50 ° of butting grooves test sides 11 are put into butting grooves can be used
To detect butting grooves angle value and butting grooves depth.
As shown in Figure 2, there is multi-purpose rotation chi 12 at the back side of main scale 1, and multi-purpose rotation chi 12 is connected to main scale 1 by bearing pin 13
On, the angled scale 14 in the back side of main scale 1.
As shown in Figure 3, revolving multipurpose rotation chi 12, by by it is multi-purpose rotation chi 12 keep to the side 15 and guiding ruler 3 be close to
The both sides of the bevel cut of part 16 to be measured, to detect whether bevel cut angle is qualified.
From above-mentioned example, in actual use, there is problems with existing welding inspection ruler：1st, when tubing to be checked
And often diameter is big for end socket, and root face size it is smaller when, welding inspection ruler can not be placed steadily, and when borrowing other rulers, meeting
Cause data distortion.2nd, weldment needs often to detect groove angle in examining, and need to often be adjusted when being examined using multipurpose ruler, grasps
Make cumbersome.3rd, the butting grooves angle detection after being assembled before welding, it is thus necessary to determine that go out actual angle whether in critical field, and weld
50 ° that connect the height gauge two ends of detection ruler and 60 ° of angle squares are the standard value of butting grooves angle, actual bevel angle and standard value
Between there is deviation, with naked eyes be difficult to determine difference whether in the range of, cause real data inaccurate.
The content of the invention
It is an object of the invention to provide the precision of bevel angle before a kind of easy to use and measurement pipeline and end socket weldering is high
