Description
One, technical field
The utility model relates to metal product bevel for welding angle checking measurements instrument, is a kind of bevel for welding detection ruler.
Two, background technology
At present in the manufacturing processing of the product that has hardware, welding is modal processing technology, usually under the situation that the quality to welding joint has higher requirements, in the manufacturing as products such as boiler, pressure vessel, boats and ships and heavy-duty machineries, can do groove to the need welding position handles, as the edge to be welded of steel plate, tubing, to reach high-quality welding and the mutually unified purpose of efficient welding, this just relates to the form design and the check of the groove in the welding technique.Domestic a lot of manufacturers adopt numerical control cutting machine or other special cutting tool equipment to carry out the groove cutting at sheet material and tubing edge mostly at present, sometimes also adopt the manual gas welding bevel cut, but which kind of cutting form all needs the bevel cut angle after the cutting is tested, the bevel cut angle is controlled in certain deviation range, to guarantee welding quality.When carrying out bevel cut measurement of angle check at present at edge to sheet material and tubing, the most frequently used instrument of staff is a welding inspection ruler, can be used for detecting various angles and weld bead height, width, welded gaps and the weld seam undercut degree of depth etc. of weldment groove, it is multiple functional, and it is comparatively accurate to detect data.
According to GB986-2008 " basic pattern of submerged-arc welding seam groove and size ", the most frequently used bevel cut angle such as steel plate, pipe fitting mainly contains 120 degree, 112.5 degree and 115 are spent three kinds, the deviate of its permission is positive and negative 2.5 degree, and corresponding butt joint groove angle is 60 degree, 45 degree and 50 degree, and the deviate of its permission is positive and negative 5 degree.
As shown in Figure 1, main scale 1 frontal left is the guiding ruler 3 of band centimeter scale 2; Main scale 1 positive right side of face is equipped with the undercut pit gauge 4 that can move up and down, one side of undercut pit gauge 4 and main scale 1 correspondence position have undercut contrast scale 5, undercut pit gauge 4 lower ends are installed with probe 6, main scale 1 lower end has level to keep to the side 7,7 be close to surface of the work by level is kept to the side, move down probe 6 and contrast undercut contrast scale 5 and can detect weld seam undercut depth value; Main scale 1 positive middle part is equipped with can move up and down many with stock rod 8, a many side and main scale 1 correspondence positions with stock rod 8 have groove contrast scale 9, many lower ends with stock rod 8 are 60 degree butt joint groove test sides 10, are 50 to spend and dock groove test sides 11 with the upper end of stock rod 8 how.Put into the gap and the groove contrast scale 9 of butt joint groove and can be used for detecting butt joint groove angle value and butt joint groove depth by observing 10,50 degree butt joint groove test sides 11,60 degree butt joint groove test sides.
As shown in Figure 2, main scale 1 back side has many with rotation chi 12, how to be connected on the main scale 1 by hinge 13 with rotation chi 12, and there is angle index 14 at main scale 1 back side.
As shown in Figure 3, revolving multipurpose rotation chi 12, by will be how with rotate chi 12 keep to the side 15 and guiding ruler 3 be close on two limits of the bevel cut of workpiece for measurement 16, whether detect the bevel cut angle [alpha] qualified.
Whether as shown in Figure 4,60 degree butt joint groove test sides 10 are put into 60 degree butt joint grooves 17 to be measured can check the first butt joint groove angle β to be measured qualified.
Whether as shown in Figure 5,50 degree butt joint grooves 18 to be measured are put in 50 degree butt joint groove test sides 11 can check the second butt joint groove angle γ to be measured qualified.
As above-mentioned example as can be known, existing welding inspection ruler is being deposited following problem in actual use: 1, groove angle detects and to be modal work in the weldment check before the weldering, but all need adjust when using multipurpose ruler to check at every turn, and is loaded down with trivial details during operating cost; 2, on-the-spot steel plate or tubing to be checked often is placed on lower position, is not easy to observation post's angle measurement degree, often can cause the multipurpose ruler displacement and make data distortion and take off the detection ruler reading; 3, the butt joint groove angle after the weldment assembling detects, need determine its actual angle whether in critical field, and 50 degree at the height gauge two ends of welding inspection ruler and 60 degree angle squares are standard values of butt joint groove angle, generally all there is difference between actual butt joint groove angle and the standard value, but only can't determine with people's naked eyes whether difference is overproof, promptly whether in required standard is worth the deviation ranges of positive and negative 5 degree, can only detect according to the butt joint groove angle before the assembling and extrapolate big probable value, cause data inaccurate.
