Description

Pipeline welding fixture
Technical field
The present invention relates to a kind of pipeline welding fixture.
Background technology
At present, in butt welding of pipelines, the general less pipeline of diameter manually hand-held butt welding, what is be relatively large in diameter is conventional Chain block adds the method for tripod to be welded again to adjust the position of two pipelines, and the error of the welding of both approaches is larger, together Heart degree is difficult to accurate control.It is relatively easy while can effectively control the pipeline of concentricity to weld it is therefore desirable to provide a kind of structure Welding fixture.
The content of the invention
The technical problem to be solved in the present invention is:Overcoming the deficiencies in the prior art, there is provided a kind of pipeline welding fixture.
The technical solution adopted for the present invention to solve the technical problems is:A kind of pipeline welding fixture, including fixed plate, institute The two ends for stating fixed plate are connected on rotatable first clamping bar and the second clamping bar, first clamping bar and opened along its length Provided with the first chute, offered along its length on second clamping bar and depression bar, the pressure are provided with the second chute, two clamping bars The two ends of bar are slidably arranged in the first chute and the second chute through bearing pin respectively, and adjusting screw rod is provided with the fixed plate, The lower end of the adjusting screw rod is connected through fixed plate with depression bar, and the adjusting screw rod rotational band dynamic pressure bar is moved up in two clamping bars It is dynamic;
The front end of first clamping bar is provided with the first chuck, and the front end of second clamping bar is provided with the second chuck, institute The lower end for stating depression bar is provided with the 3rd chuck, and the inner top side of three chucks is formed on bench port, three bench ports respectively respectively It is provided with fastening bolt.
Further, the front end of first clamping bar and the second clamping bar forms bending section, first chuck and respectively Two chucks are separately positioned on the bending section of two clamping bars.
Further, the upper end of the adjusting screw rod is provided with cross bar.
The beneficial effects of the invention are as follows:It can be clamped the pipeline of two need welding, it is to avoid to produce big concentricity and miss Difference, while improving weldquality.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of weld jig of the present invention;
Fig. 2 is schematic diagram when weld jig clamps two steel pipes;
Wherein, 1, fixed plate, the 2, first clamping bar, the 3, second clamping bar, 4, depression bar, 5, adjusting screw rod, the 21, first chuck, 31, Second chuck, the 41, the 3rd chuck.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of pipeline welding fixture, including fixed plate 1, the two ends of fixed plate 1 are connected to rotatably The first clamping bar 2 and the second clamping bar 3, offer along its length on the first chute, the second clamping bar 3 along length on the first clamping bar 2 Direction offers and depression bar 4 is provided with the second chute, two clamping bars, and the two ends of depression bar 4 are slidably arranged in the first cunning through bearing pin respectively In groove and the second chute, adjusting screw rod 5 is provided with fixed plate 1, the lower end of adjusting screw rod 5 connects through fixed plate 1 with depression bar 4 Connect, the rotational band dynamic pressure bar 4 of adjusting screw rod 5 is moved on two clamping bars.
The front end of first clamping bar 2 is provided with the first chuck 21, and the front end of the second clamping bar 3 is provided with the second chuck 31, depression bar 4 Lower end be provided with the 3rd chuck 41, the inner top side of three chucks is formed respectively to be set respectively on bench port, three bench ports There is fastening bolt.
The front end of first clamping bar 2 and the second clamping bar 3 forms bending section respectively, and the first chuck 21 and the second chuck 31 are set respectively Put on the bending section of two clamping bars.The upper end of adjusting screw rod 5 is provided with cross bar.
As shown in Fig. 2 work when, first first pipeline is placed between three chucks, then rotate adjusting screw rod 5 until The wall contacts of three chucks and first pipeline, now, the bench port of three chucks do not connect with first pipeline outer wall Touch, second pipeline is then now put between the bench port of three chucks, two duct end wall contacts rotate three respectively Fastening bolt on chuck again fixes second pipeline, now starts to weld two pipelines again, due to two pipes Concentricity between road passes through the regulation of three fastening bolts, therefore concentricity is protected, and will not be deformed because of chuck And be affected.
Using the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
