Description
Technical field
It the utility model is related to pipeline and end socket product groove angle examine survey tool, particularly a kind of combined type
Weld groove detection ruler.
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 manufacture of pressure pipeline, pressure vessel, boiler product, often relate to big
The pressure parts such as bore, wall thickness part, require in welding procedure to do groove processing in advance to welding position, as pipeline, end socket treat toe
Edge, it can be related to groove to ensure welding quality, in welding procedure and open up and examine.Most domestic manufacturer uses at present
The groove that Numerical control cutting carries out tubing opens up, and also uses automatic cutting bevelling sometimes, but no matter which kind of cutting form is used, and all needs
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 high for detecting the angle of welding groove and weldering, and it is more accurate that it detects data.
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 3,1 positive right side of face of main scale 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 are stung with undercut contrast scale 5
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；1 positive Middle face of main scale 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 contrast scale 9 with groove, use stock rod 8
Lower end be 60 ° of butting grooves test sides 10, use stock rod 8 upper end be 50 ° of butting grooves test sides 11.By observing 60 °
The gap and groove contrast scale 9 that 10,50 ° of butting grooves test side butting grooves test side 11 is 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, it is whether qualified to detect bevel cut angle.
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 when root face size is smaller, 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 weldering, it is thus necessary to determine that go out actual angle whether in critical field, and weld
Connect 50 ° of the height gauge both ends of detection ruler and 60 ° of angle squares be butting grooves angle standard value, actual bevel angle and standard value
Between deviation be present, with being visually difficult to determine that difference whether in the range of, causes real data inaccurate.
