Now hereinafter in conjunction with Fig. 1 a and 1b, and Fig. 2 a and Fig. 2 b pipe fitting external diameter positioner that comes the example explanation to use according to the interior Welding machine of circumferential weld system of an embodiment of the utility model.

Fig. 2 a and Fig. 2 b illustrate the part cutout front view and the vertical view of a kind of pipe fitting external diameter positioner that the interior Welding machine of circumferential weld system according to an embodiment of the utility model uses.Need to understand, these figure only are schematic diagrames, and it is also drawn not according to actual ratio, and for the sake of clarity may partly cut or not draw some parts open.And wherein with dashed lines is drawn the lines that are blocked for integrality.

According to an embodiment of the present utility model, shown in Fig. 2 a and Fig. 2 b, lay the pipe fitting external diameter positioner 17 that is provided with on the platform 6 at this pipe fitting and can comprise V-type locating piece device 25 and oblique-wedge clamping system 26.For diagram more clearly, V-type locating piece device 25 is cut open along the line B-B ' among Fig. 2 b in Fig. 2 a, and the flange part 15 that in Fig. 2 b, not have drafting to weld together with pipe fitting 14.

As among Fig. 2 a as seen, V-type locating piece device 25 can comprise main part and two V-type locating pieces of layout spaced apart up and down.Main part is fixed on pipe fitting in detachable and/or adjustable mode and lays on the platform 6.Oblique-wedge clamping system 26 can comprise column 28 and the wedge slide plate 29 with pass chute 30.Column 28 is fixed on pipe fitting in detachable and/or adjustable mode and lays on the platform 6.Wedge slide plate 29 has certain width in vertical direction, and its first half has towards away from an end of the column wedge structure of taper (attenuation) gradually.Alternatively, the part of wedge slide plate 29 in the outside of column 27 is a transverse handle 27, so that the operator operates.

Wedge slide plate 29 can slide front and back in pass chute 30.Alternatively, pass chute 30 is in vertical direction roughly between two V-type locating pieces of V-type locating piece device 25.When loading pipe fitting 14, can spur transverse handle 27 earlier wedge slide plate 29 is slided backward, expose two V-type grooves between the V-type locating piece.Pipe fitting 14 is placed within this V-type groove subsequently, and push transverse handle 27 with wedge slide plate 29 to front slide, its first half is contacted with pipe fitting 14 also gradually pipe fitting 14 is pressed to the V-type groove, thus by the chucking power between wedge slide plate 29 and the V-type groove that pipe fitting 14 is fixing when slide plate 29 stops.

When welding is finished, also can slide backward slide plate easily, thereby unclamp pipe fitting 14 and take off pipe fitting 14 from the V-type groove.

Now hereinafter in conjunction with Fig. 1 a and 1b, and Fig. 3 a and Fig. 3 b come the example explanation according to the interior Welding machine of circumferential weld system of an embodiment of the utility model use can three-dimensional regulation welding gun.

Fig. 3 a and Fig. 3 b illustrate that interior Welding machine of circumferential weld system according to an embodiment of the utility model uses can three-dimensional regulation the front view and the vertical view of welding gun.Need to understand, these figure only are schematic diagrames, and it is also drawn not according to actual ratio, and for the sake of clarity may partly cut or not draw some parts open.And wherein with dashed lines is drawn the lines that are blocked for integrality.

Shown in Fig. 3 a, in embodiment of the present utility model, pneumatic welding gun 24 is fixed to rotation base plate 35.Shown in Fig. 3 b, have a plurality of annular slotted holes 36 on this rotation base plate 35, screw thread column cap on the inclined floor 32 and so on can pass these annular slotted holes 36, be fixed together with inclined floor 32 thereby can will rotate base plate 35 by nut.Annular slotted hole 36 extends certain width in a circumferential direction, thereby can be so that rotation base plate 35 can rotation two-dimensionally in the plane of inclined floor 32.Overlooking of Fig. 3 b there is shown four annular slotted holes 36 and two column caps, however of the present utility model in this respect without limits.

In addition, shown in Fig. 3 b, an end of inclined floor 32 is pivotably connected to horizonal base plate 31 by mandrel 37.The other end centre position of inclined floor 32 has the elongate slot 33 that extends along its length.The thread pillar 34 that one end is fixed to horizonal base plate 31 pivotly can pass this elongate slot, thereby can cooperate suitable pads that inclined floor 32 is fixed on different angles with two nuts in inclined floor both sides about in the of 32 on the thread pillar 34.

Therefore,, realized the adjustment of pneumatic welding gun 24 on three dimensions, so that be fit to dissimilar and big or small pipe fitting and flange part by above configuration.

The welding operation according to Welding machine of circumferential weld system in the double of the utility model embodiment is used in following simple declaration.Electric rotating machine drives two pipe fittings and lays platform 6 and be rotated in this system, rotates simultaneously thereby drive two pipe fittings 14.

At first, on the station in double in the Welding machine of circumferential weld system, pulling transverse handle 27 slides backward wedge slide plate 29, exposes two V-type grooves between the V-type locating piece.Pipe fitting 14 is placed within this V-type groove subsequently, and push transverse handle 27 with wedge slide plate 29 to front slide, its first half is contacted with pipe fitting 14 also gradually pipe fitting 14 is pressed to the V-type groove, thus by the chucking power between wedge slide plate 29 and the V-type groove that pipe fitting 14 is fixing when slide plate stops.Repeat said process for a station in the Welding machine of circumferential weld system in the double subsequently, thereby fix another pipe fitting 14.

Afterwards, can carry out three-dimensional regulation and send to each welding gun, thereby its arc welding gun head 23 be located in the position of weld seam.

Set various operating parameters by switch board 4, such as rotary speed etc.

Finish can starter motor after setting rotation and the welding of air gun, thereby finish girth welding by the rotation of motor.

When welding is finished, also can slide backward slide plate easily, thereby unclamp pipe fitting 14 and take off the pipe fitting 14 that has welded flange part 15 from the V-type groove.

Although the utility model is described in conjunction with its concrete illustrative embodiments, what easily see is, multiple alternative, revise and distortion is easily seen for those skilled in the art.Thus, be schematically and also non-limiting in this illustrative embodiments of the present utility model of illustrating.Can under the situation that does not break away from spirit and scope of the present utility model, modify.

Employed in this disclosure measure word " one ", " a kind of " etc. do not get rid of plural number.Any Reference numeral in claims all should not be construed as the restriction to scope.
