Detailed description of the invention
As shown in Figure 1 and Figure 2, steel pipe flange positioning fixture for welding of the present invention comprises radial location block 12, radial pressure block 4, nut 2, pad 3, alignment pin 1, axial location block 11, flange block plate 5, short alignment pin 6, pad 7, nut 8, rotary handle 9.Radial pressure block 4, radial location block 12, axial location block 11 and flange block plate 5 are arranged in alignment pin 1 from left to right successively, and axial location block 11 is placed between radial location block 12 and flange block plate 5, and its external diameter is greater than steel pipe 13 internal diameter, and is close to flange 10; Radial location block 12 external diameter is less than steel pipe 13 internal diameter and be close to steel pipe inner wall, is provided with conical central hole in the middle part of it; Radial pressure block 4 is provided with the male cone (strobilus masculinus) forming taper fit with the inner conical surface of radial location block 12, and is provided with the centre bore forming interference fits with alignment pin 1, and one end of radial pressure block 4 is inserted in the conical central hole of radial location block 12 also to be formed and closely cooperated; Nut 2 and the pad 3 of locking are housed at the left end of alignment pin 1, at the right-hand member of alignment pin 1, nut 9 and pad 8 are housed; Flange block plate 5 is provided with the centre bore with alignment pin 1 interference fits, circumference is distributed with the pin-and-hole of 3 groups of different sizes, correspond to the flange of 3 kinds of specifications that flange bolt hole center circle diameter is respectively Φ B, Φ C, Φ D, every 3 one group, locate short pin 6 through flange 3 bolts hole wherein and 3 locating holes of flange block plate, realize flange radial location.
Radial location block 12 of the present invention by three shapes identical, the arc block that can be separated from each other encloses to connect and forms, its circumference is evenly equipped with 6 through holes, can weight reduction, sees shown in Fig. 3 and Fig. 4.
One end that alignment pin 1 of the present invention stretches out flange block plate 5 is provided with the through hole can extracting and insert rotary handle 9 at any time.
The external diameter of axial location block 11 of the present invention is less than flange inner diameter, larger than pipe diameter, by axial location block, limits the distance of steel pipe right side and flange right side, realizes steel pipe flange axial location.
The operation principle of steel pipe flange positioning fixture for welding of the present invention is as follows:
First steel pipe 13 left end clamping on the chuck of automatic soldering device, then flange 10 is pressed in flange block plate 5 left side of fixture of the present invention, and inserts short alignment pin 6 pairs of flanges 10 and carry out radial location.Steel pipe is put in the one end of then fixture of the present invention being equipped with radial location block 12, and makes axial location block 11 near steel pipe 13 right side, and axial location block 13 also just limits the distance of steel pipe right side and flange right side, thus realizes steel pipe flange axial location.On the other hand, artificial use spanner fastening nut 8, avoids the rotation of alignment pin 1 by fixing rotary handle 9 in the process of fastening nut 8.Along with nut 8 is constantly tightened, the nut 2 of left end and pad 3 constantly will compress radial pressure block 4 to the right, radial pressure block 4 produces radial pressure to radial locating piece 12 makes it outwards open and hold out against steel pipe inner wall, thus makes steel pipe, alignment pin and flange coaxial, i.e. steel pipe and flange coaxial.Steel pipe and flange position are all fixed, and during the startup of automatic soldering device, steel pipe, flange and fixture all synchronous axial system, carry out automatic welding to steel pipe and flange.
