Description
Technical field
The invention belongs to bend welding tool fields, and in particular to a kind of elbow pipe welding fixture.
Background technique
Often use some pipe connecting devices with camber in certain special product facilities, and part bend pipe
Connection need to be realized with welding, however when welding each section of pipe fitting, operator would generally be by each section of pipe fitting by drawing
It is required that putting on the table, spot welding positioning is then carried out, finally turns the welding for carrying out another side again, in certain
The bend pipe of angle connects, and can only weld by pipe section to fetching, this welding manner can greatly increase operator
Working strength, and do not ensure that whether the angle after welding meets drawing requirement, to reduce welding quality.
Summary of the invention

Inventive technique solution
In order to achieve the above-mentioned object of the invention, the present invention uses following technical solutions:
A kind of elbow pipe welding fixture, including bottom plate, the bottom plate both ends are provided with cushion block, offer axis on the cushion block
The hole of line in the horizontal direction is provided with welding bolt in hole, is detachably connected between the cushion block at the bottom plate both ends useful
In the positioning device of fixation jointed tubular workpieces to be welded.
Preferably, the positioning device includes several V-blocks being set on the bottom plate, and the V-block top surface is opened
Equipped with V-groove, the V-block top is rotatably connected to pressing ring, and the pressing ring and V-groove corresponding position offer arc groove, when
Pressing ring turns to the fixed part that V-groove and arc groove when one side is bonded with V-block top surface collectively form fixed jointed tubular workpieces to be welded；Institute
V-block is stated to be detachably connected with opposite side at pressing ring rotation connection.
Preferably, the axis in the hole on the cushion block and the V-block top surface are located at same level.
Preferably, the cushion block and V-block are existed by the hole being opened on bottom plate and the screw or pin connection that cooperate with hole
On bottom plate.
Preferably, hole site is determined according to each section of angle intersection point of bend pipe on the bottom plate, so as to more accurately assembly positioning
Device, the angle position of each section of bend pipe of centering.
Preferably, welding bolt is provided in the hole on cushion block.
Preferably, the bottom plate two opposite side walls are provided with handle.
Advantages of the present invention
The present invention has the advantages that
A kind of elbow pipe welding fixture of the invention, clamping pipe fitting to be welded that can be quick, stable, clamped one time and can
More piece bend pipe is positioned well, accurately and reliably, so as to avoid position degree deviation caused by artificial butt welding, reduces zero
Time used in part docking, butt welding, welding quality is improved, improves solder yield.

Specific embodiment
In conjunction with summary of the invention general introduction and attached drawing, the specific embodiment that the present invention will be described in detail.
A kind of elbow pipe welding fixture, including bottom plate 2,2 left and right side walls of bottom plate are provided with handle 13.2 liang of the bottom plate
End is provided with cushion block 1, and the hole of axis in the horizontal direction is offered on the cushion block 1, and welding bolt 12, Kong He is provided in hole
Bushing 11 is additionally provided between welding bolt 12, when use, the welding bolt 12 was inserted into the both ends of bend pipe to be welded respectively,
To avoid the contraction distortion of nozzle after welding.Be removably connected between the cushion block 1 at 2 both ends of bottom plate for it is fixed to
The positioning device of weld-end fittings.
The positioning device includes the V-block 3 that several are set on the bottom plate 2, and 3 top surface of V-block offers V
Type groove, 3 top of V-block are rotatably connected to pressing ring 6, and the pressing ring 6 offers arc groove with V-groove corresponding position, works as pressure
Circle 6 turns to the fixed part that V-groove and arc groove when one side is bonded with 3 top surface of V-block collectively form fixed jointed tubular workpieces to be welded；Institute
It states V-block 3 and is detachably connected with opposite side at 6 rotation connection of pressing ring using eyelet bolt 4 and wing nut 5.It will when use
Jointed tubular workpieces to be welded are respectively disposed on V-block 3, are compressed it and are reinforced by pressing ring 6, then will be pressed with eyelet bolt 4 and wing nut 5
Circle 6 is fixed on V-block 3.
The axis in the hole on the cushion block 1 and 3 top surface of V-block are located at same level.
The cushion block 1 and V-block 3 are connect by the hole that is opened on bottom plate 2 and the screw 8 cooperated with hole or straight pin 10
On a base plate 2.Hole site is determined according to each section of angle intersection point of bend pipe on the bottom plate 2, more accurately to assemble positioning device,
The angle position of each section of bend pipe of centering.The angle of pipe fitting to be welded can be adjusted, by rotating V-block 3 to guarantee between each part
