Description
Technical field
The invention belongs to welding technology field, more particularly to a kind of earth wire clamp.
Background technology
Submerged-arc welding is that a kind of electric arc burns the method welded under welding flux layer.Its intrinsic welding quality stable, weldering
Yield of delivering a child is high, without arc light and the advantages of seldom flue dust, becomes the important steel such as pressure vessel, pipeline section manufacture, box beam column
Main welding method in structure fabrication.Carrying out last one of girth welding technique of the tubular products such as pressure vessel, drum
When, it is that will be placed on the rolling wheel support being arranged symmetrically to carry out arc welding by welded tube body, quilt is reconnected using earth wire clamp ground wire
Welded tube body ensures that welding machine provides stable welding current, so as to ensure welding quality.In the prior art, earth wire clamp is clamped in and welded
Body end edge is realized to be rotated in connection, welding process by welded tube body under the drive of roller, and earth wire clamp is followed by welded tube body
Rotate, ground wire can be wrapped on earth wire clamp, earth wire clamp pulls generation loosening by ground wire or ground wire is pullled by earth wire clamp and departs from ground,
At this moment welding current will be caused unstable, so that occurring spark phenomenon causes to be welded tube surfaces burn.
The content of the invention
It is an object of the invention to provide a kind of earth wire clamp, earth wire winding is avoided in welding process around earth wire clamp, it is ensured that weldering
Connect electric current stable.
To achieve these goals, the present invention takes following technical scheme：A kind of earth wire clamp, including leading of being connected with ground wire
Torch, the in addition to fixed clamp mounting bracket on by welded tube body, contact rod and mounting frame are connected into rotating, and contact rod
Shaft core and the centerline parallel by welded tube body.
In above-mentioned technical proposal, mounting bracket is fixedly connected with by welded tube body, and one end of contact rod is contacted with mounting bracket, in addition
One end is connected with ground wire, and the shaft of contact rod and mounting frame are connected into rotating, when rotation by welded tube body, contact rod also phase
Mounting bracket is rotated, at this moment ground wire will not be wrapped on earth wire clamp, and mounting bracket, ground wire are all without pine in whole welding process
Move, come off, it is ensured that stable welding current is so as to ensure welding quality.
Brief description of the drawings
Fig. 1 is schematic perspective view of the present invention；
Fig. 2 is sectional view of the present invention.
Embodiment
Made further instructions with reference to accompanying drawing 1,2 couples of present invention：
A kind of earth wire clamp, including the contact rod 10 being connected with ground wire, in addition to fixed clamp the installation on by welded tube body A
Frame 20, contact rod 10 is constituted to rotate with mounting bracket 20 and is connected, and the shaft core of contact rod 10 and the centerline parallel by welded tube body A.
Mounting bracket 20 is fixedly connected with by welded tube body A, and one end of contact rod 10 is contacted with mounting bracket 20, and other end is connected with ground wire,
The shaft of contact rod 10 is constituted to rotate with mounting bracket 20 and is connected, and when rotation by welded tube body A, contact rod 10 is also mounted opposite frame
20 are rotated, and at this moment ground wire will not be wrapped on earth wire clamp, in whole welding process mounting bracket 20, ground wire all without loosening, it is de-
Fall, it is ensured that stable welding current is so as to ensure welding quality.
Bearing 21 is disposed between described mounting bracket 20 and contact rod 10.It is used to limit the phase of contact rod 10 using bearing 21
