Description

Fountain type stringing exchanger tubes and tubesheets deep hole welding assembles positioning device
Technical field
The utility model relates to a kind of positioning devices, and in particular to the assembly of fountain type stringing exchanger tubes and tubesheets deep hole welding Positioning device belongs to heat exchange pressure vessel and equipment manufacturing technology field.
Background technique
After prior art exchanges heat pipe and the assembly of pipe sheet deep hole welding line position, without other safeguard measures, subsequent weldering is caused When connecing, rigging position variation is unable to satisfy welding requirements;Fountain type stringing causes tube bank spatial position irregular simultaneously, assembly Precision is difficult to ensure.
Utility model content
The purpose of the utility model is to provide fountain type stringing exchanger tubes and tubesheets deep hole weldings to assemble positioning device, with solution The problem of certainly fountain type cloth heat exchange tube lacks positioning tool when welding installation.
It includes casing, adjustment axis, top tight pieces, positioning that fountain type stringing exchanger tubes and tubesheets deep hole welding, which assembles positioning device, Plate, adjustable support and locating shaft;
Adjustment axis is horizontally arranged on the adjustable side of two adjustable supports, and the both ends of adjustment axis are mounted on positioning plate, Multiple mounting holes are equidistantly provided on positioning plate, the mounting hole on two positioning plates is oppositely arranged, and locating shaft is mounted on opposite set In two mounting holes set, pipe sleeve is covered in adjustment axis, and casing can slide in adjustment axis, top tight pieces are fixedly mounted on casing Outer wall on, the other end of top tight pieces leans with pipe fitting to be welded.
Preferred: top tight pieces are cylinder, hydraulic cylinder or electric pushrod.
Preferred: adjustable support is jack or electric pushrod.
The utility model has the effect that compared with existing product
Adjustment axis can by adjustable support adjust top tight pieces height, adjustment axis can by the mounting hole on positioning plate, Top tight pieces are adjusted at a distance from pipe fitting to be welded, after the output end of top tight pieces holds out against the curved end of pipe fitting to be welded, pipe fitting to be welded can be made Positioning is fitted close and realized with pipe sheet deep hole position while welding, meets the requirement of assemble welding size, to heat exchanger tube and pipe sheet deep hole After the completion of weldering, the spatial position of top tight pieces is adjusted, ressembles new heat exchanger tube.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of fountain type stringing exchanger tubes and tubesheets deep hole welding assembly positioning device;
Fig. 2 is the structural schematic diagram of specific embodiment.
In figure: 1- casing, 2- adjustment axis, 3- top tight pieces, 4- positioning plate, 5- adjustable support, 6- locating shaft.
Specific embodiment
The utility model preferred embodiment is elaborated below according to attached drawing.
As depicted in figs. 1 and 2, fountain type stringing exchanger tubes and tubesheets deep hole welding assembly positioning described in the utility model Device includes casing 1, adjustment axis 2, top tight pieces 3, positioning plate 4, adjustable support 5 and locating shaft 6;
Adjustment axis 2 is horizontally arranged on the adjustable side of two adjustable supports 5, and adjustment axis 2 can pass through bolt group activity It is mounted on adjustable support 5, can also be fixedly mounted on by welding on adjustable support 5, the both ends of adjustment axis 2 It is mounted on positioning plate 4, grafting can be used in the mounting means of adjustment axis 2 and positioning plate 4, and limits by bolt or pin shaft, can The spatial position of adjustment axis 2 is adjusted, is equidistantly provided with multiple mounting holes on positioning plate 4, the mounting hole on two positioning plates 4 is opposite Setting, locating shaft 6 are mounted in two mounting holes being oppositely arranged, and the mounting means of locating shaft 6 and positioning plate 4 can also be used slotting Connect, and limited by bolt or pin shaft, 1 set of casing in adjustment axis 2, and casing 1 can slide in adjustment axis 2, and top tight pieces 3 are solid Dingan County can be used on the outer wall of casing 1 and be bolted or weld, the other end of top tight pieces 3 leans with pipe fitting to be welded.
Further, top tight pieces 3 are cylinder, hydraulic cylinder or electric pushrod.
Further, adjustable support 5 is jack or electric pushrod.
Working principle: it is fixed on mounting plate after tube bank pipe support assembly, adjustable support 5 and locating shaft 6 is fixed on On platform, after heat exchanger tube penetrates tube bank pipe support, according to various heat exchange tube space position difference, adjustment axis 2 passes through on positioning plate 4 Mounting hole adjusts the position of top tight pieces 3, after position suitable, adjusts top tight pieces 3 and holds out against heat exchanger tube curved end, make heat exchanger tube and pipe Plate Deep Hole Welding position while welding is fitted close, and meets the requirement of assemble welding size, after the completion of heat exchanger tube and pipe sheet deep hole weldering, is adjusted This assembly positioning device, turns again with new heat exchanger tube, until whole heat exchanger tube welding are completed.
This embodiment is just an exemplary description of this patent, does not limit its protection scope, those skilled in the art Member can also be changed its part, as long as it does not exceed the essence of this patent, within the protection scope of the present patent.
