Abstract
The utility model discloses a positioning device for assembling and welding a connecting pipe and a flange. The positioning device comprises a core rod and a core disc, wherein the core rod and the core disc are respectively cylindrical, the core rod is vertical to the end surface of the core disc, the core rod is fixedly connected at the center of the end surface of the core disc, and the core rod and the core disc are coaxial. According to the positioning device for assembling and wielding the connecting pipe and the flange, the connecting pipe and the flange are accurately positioned and then are welded and formed, so that the problems that in the traditional welding method of the flange and the connecting pipe, as the positions of the flange and the connecting pipe are determined by an angle ruler or naked-eye observation, the deviation is easily caused, the coaxiality of the flange and the connecting pipe as well as the verticality of a flange sealing surface and the pipe can not be ensured, and the quality of a product is reduced can be solved.
Description
Technical field
The utility model relates to a kind of pipe connecting flange assembly welding positioner.
Background technology
Flange is the equipment medium import and export, when the important component that pipeline connects, flange weld with adapter, guarantees that flange is vertical particularly important with the adapter center line with flange sealing surface with the axiality of adapter.Conventional flange and the way of taking over welding are to confirm that with angle square or naked-eye observation the position of flange and adapter welds, and so just deviation occurs easily, can't guarantee the axiality of flange and adapter and the perpendicularity of flange sealing surface and adapter, the reduction product quality.
The utility model content
The purpose of the utility model is to provide a kind of pipe connecting flange assembly welding positioner; Can be with taking over and flange accurate positioning welding fabrication again; Solved conventional flange and the way of taking over welding and be with angle square or naked-eye observation and confirmed that the position of flange and adapter welds; So just deviation occurs easily, can't guarantee the axiality of flange and adapter and the perpendicularity of flange sealing surface and adapter, reduce the problem of product quality.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of pipe connecting flange assembly welding positioner comprises plug and core dish, and plug and core dish are respectively cylindric, and plug is vertical with core dish end face, and plug is fixedly connected on the center of core dish end face, and plug and core dish are coaxial.This pipe connecting flange assembly welding positioner is the pipe connecting flange according to different size, a collection of positioner of making, and it is made up of plug and core dish, will take over flange to be enclosed within on the plug; Accurate positioning, welding fabrication again is after assembly is installed; Guaranteed that flange and flange, flange and valve etc. effectively make up, do not produced the gap, reduced internal stress; Guarantee security of operation, guaranteed the axiality of flange and adapter and the perpendicularity of flange sealing surface and adapter, guarantee product quality.
As preferably, said plug and core dish are structure as a whole.Guarantee the intensity of this pipe connecting flange assembly welding positioner, improve service life, and accurate plug and the axiality of core dish and the perpendicularity of plug and core dish end face, the quality of locating guaranteed.
As preferably, the diameter of said plug cooperates with the aperture of the flange of assembly welding and adapter.This pipe connecting flange assembly welding positioner is the pipe connecting flange according to different size, and the positioner of a collection of coupling of making guarantees the quality of locating.
The beneficial effect of the utility model is: (1), improved product quality has guaranteed the axiality of flange and adapter and the perpendicularity of flange sealing surface and adapter; (2), do not produce the gap, minimizing internal stress, assurance security of operation after flange and the adapter welding.
Description of drawings
A kind of structural representation when Fig. 1 is the utility model use;
Among the figure: 1, plug, 2, the core dish, 3, flange, 4, take over, 5, weld seam.
The specific embodiment
Pass through specific embodiment below, and combine accompanying drawing, the technical scheme of the utility model is done further to specifically describe:
Embodiment: shown in accompanying drawing 1, a kind of pipe connecting flange assembly welding positioner comprises plug 1 and core dish 2; Plug 1 is respectively cylindric with core dish 2; Plug 1 is vertical with core dish 2 end faces, and plug 1 is fixedly connected on the center of core dish 2 end faces, and plug 1 is coaxial with core dish 2; Plug 1 is formed in one with core dish 2, and the diameter of plug 1 cooperates with flange of assembly welding 3 and the aperture of taking over 4.
When this pipe connecting flange assembly welding positioner uses, through plug 1 and core dish 2 axiality accurately that has and the perpendicularity accurately that plug 1 and core dish 2 end faces have, will take over 4 and flange 3 be enclosed within on the plug 1; Accurately locate, welding fabrication forms accurate weld seam 5 again, after assembly is installed; Guaranteed that flange and flange, flange and valve etc. effectively make up; Do not produce the gap, reduce internal stress, guarantee security of operation; Guarantee flange 3 and axiality and flange 3 sealing surfaces and the perpendicularity of taking over 4 of taking over 4, guaranteed product quality.
Above-described embodiment is a kind of preferable scheme of the utility model, is not the utility model is done any pro forma restriction, under the prerequisite that does not exceed the technical scheme that claim puts down in writing, also has other variant and remodeling.
Claims (3)
1. a pipe connecting flange assembly welding positioner is characterized in that, said pipe connecting flange assembly welding positioner comprises plug and core dish; Plug and core dish are respectively cylindric; Plug is vertical with core dish end face, and plug is fixedly connected on the center of core dish end face, and plug and core dish are coaxial.
2. pipe connecting flange assembly welding positioner according to claim 1 is characterized in that said plug and core dish are structure as a whole.
