Specific embodiment
Name preferred embodiment, and become apparent from completely illustrating the utility model with reference to attached drawing.
As shown in Figs 1-4, a kind of fixture 10 for pipeline welding, includes：Two pedestals 100, two center-poles 200,
First connector 300 and the second connector 400, tightening piece 500 and fastening assembly 600.Pedestal 100 is equipped with V-shaped groove 110, center
Hole 120, tightening hole 130 and clamping portion 140.V-shaped groove 110 is used to accommodate pipeline 20.Centre bore 120 runs through pedestal 100.Tightening hole
130 is threaded hole and are connected with centre bore 120.Two center-poles 200 are slidedly arranged on the centre bore 120 of two pedestals 100 respectively.First
Connector 300 is fixedly arranged on one in two center-poles 200, and the second connector 400 is fixedly arranged on another in two center-poles 200,
First connector 300 is pivotably coupled to the second connector 400.Tightening piece 500 is connected through a screw thread with tightening hole 130, and
One end of tightening piece 500 holds out against center-pole 200.Fastening assembly 600 includes sequentially connected fixed part 610, restraint zone 620 and lives
Dynamic portion 630, fixed part 610 are fixedly arranged on pedestal 100, and movable part 630 is removably arranged in clamping portion 140, and restraint zone 620 is successively
Across two faces of V-shaped groove 110 for tightening pipeline 20.
More than, two tubing 21 of pipeline 20 can be respectively placed on V-shaped groove 110 and be tightened using fastening assembly 600, pipe fitting
22 two tubing 21 of connection.Advantageously realize positioning when pipeline 20 welds so that the welding of pipeline 20 is smoothed out；While first
Angle between 300 and second connector 400 of connector can adjust, convenient for the welding of bend pipe.
Also, the fixture 10 for pipeline welding in the present embodiment is not only to include two pedestals 100, but in total

Restraint zone 620 is simultaneously not located in trough of belt 150, that is to say, that trough of belt 150 does not play the role of limiting at this time.It is alternative to implement
In example, using the tubing of relatively small caliber, when tightening, restraint zone can pass through trough of belt, and two edges of restraint zone are limited by trough of belt
It lives calmly.Specifically, as shown in FIG., each pedestal 100 is equipped with two troughs of belt 150, the bottom surfaces of two troughs of belt 150 respectively with V-shaped groove 110
Two faces connection and be recessed respectively relative to two faces of V-shaped groove 110.In order to clamp the smaller pipeline 20 of caliber.
In the present embodiment, center-pole 200 is square pole.Pedestal 100 has the first wainscot wall area 160 and the second wainscot wall area 170,
First wainscot wall area 160 includes the periphery edge of centre bore 120 and the outline border of pedestal 100, and the second wainscot wall area 170 is connected to centre bore
Between 120 periphery edge and the outline border of pedestal 100, the thickness of the first wainscot wall area 160 is more than the thickness of the second wainscot wall area 170.The
One wainscot wall area 160 is used to strengthen the structure of corresponding region, and the second wainscot wall area 170 is used to mitigate weight.
In addition, as shown in Figure 2 and Figure 4, the first connector 300 and the second connector 400 are connected by connecting pin 350, with
Realize relative rotation.Fixture 10 for pipeline welding further includes spacer pin 700.First connector 300 is equipped with the first limit hole
310, the second connector 400 is equipped with several second limit holes 410 (being specially 3 in figure).In the first connector 300 relative to
During two connectors 400 rotate, the first limit hole 310 is aligned successively with several second limit holes 410.Spacer pin 700 is used
In being arranged in the first limit hole 310 and the second limit hole 410 to limit the opposite of the first connector 300 and the second connector 400
Rotation.In this way, the first limit hole 310 can be aligned from the second different limit holes 410, pass through, make for spacer pin 700 after alignment
It obtains the first connector 300 and the second connector 400 is located in different angles.
Specifically, spacer pin 700 has head 710, upper pole part 720 and the lower bar portion 730 that diameter becomes smaller successively, upper boom
Portion 720 is contacted with the outer surface of the first connector 300, specially the lower surface of upper pole part 720 and the upper table of the first connector 300
Face contacts.Lower bar portion 730 is arranged in the first limit hole 310 and the second limit hole 410.Spacer pin 700 can pass through from top to bottom
First limit hole 310 and the second limit hole 410, and desired location is rested on, it is facilitated to play position-limiting action, the head being relatively large in diameter
Portion 710 also allows for operating personnel and picks and places.
As shown in figure 3, tightening hole 130 is set on the bottom surface of pedestal 100, tightening piece 500 is interior hex head fastener.Tightening piece
500, which may be used allen wrench, conveniently realizes assembly and disassembly, and tightening piece 500 can be fully located in pedestal 100, do not influence bottom
Seat 100 is put.
More than, then pipeline 20 is placed in bottom by the angle of the first connector 300 adjustable first and the second connector 400
On the V-shaped groove 110 of seat 100, later again so that movable part 630 blocks buckling groove to tighten pipeline 20, clamping is completed, can be carried out
Welding job.In welding process, since tubing 21 is pinioned so as to exceptionally straight, tubing 21 is heated to the increased direction expansion of diameter,
Act on pipe fitting 22 so that the welding surface of pipe fitting 22 eliminates the gap between tubing 21 and pipe fitting 22, realize pipe close to tubing 21
Welding is completed in the combination of material 21 and pipe fitting 22.After the completion of welding, movable part 630 takes out from buckling groove, you can takes pipeline 20
Under.Operation is very simple, light, laborsaving；And it is easy to carry and not affected by environment, it is carried out convenient for construction and administrative staff
The operation of construction site；Use scope is wide, can be adapted for the electric fusion welding of common most of bore polyethylene pipes, not by
The limitation of outer diameter tube and wall thickness.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Under the premise of the principle and essence without departing substantially from the utility model, many changes and modifications may be made,
But these change and modification each fall within the scope of protection of the utility model.
