The sliding mold is provided with a gap adjustment device used for adjusting the joint gap of the pipe I and the pipe II. According to the joint gap locating device for welding the pipeline openings of the utility boiler, the pipes can be coaxially and quickly clamped, the joint gap can be conveniently adjusted, operation is simple, and the work efficiency is improved.

Description

A kind of station boiler pipeline mouth of pipe welding alignment clearance positioner
Technical field
The present invention relates to positioning tool technical field, be specifically related to a kind of station boiler pipeline mouth of pipe welding alignment clearance positioner.
Background technology
At present in station boiler installing area, the adjustment counterpart work that the many uses of counterpart operation during small-bore loose pipe welding are docked the mouth of pipe to brank, although brank is carried out to the concentricity that counterpart can guarantee to dock the mouth of pipe but utilize, but be difficult to guarantee the alignment clearance between two mouths of pipe, if the too small problems of welded quality such as not weld penetration, undercut, pore that easily cause of the alignment clearance between two mouths of pipe, and buy higher to the expense of brank.
Summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides a kind of structure to add station boiler pipeline mouth of pipe welding alignment clearance positioner single, that can guarantee alignment clearance.
The present invention overcomes the technical scheme that its technical problem adopts:
This station boiler pipeline mouth of pipe welding alignment clearance positioner, comprise fixed die, be vertically fixed on support on fixed die, by adjusting device, can move up and down the sliding die being fixed on support and be installed on respectively the some arcs in fixed die and sliding die, the axis of each arc in described fixed die and sliding die coincides, fixed die and sliding die fix the pipe I of two needs welding and pipe II by arc, are provided with for adjusting the gap adjusting device of pipe I and pipe II alignment clearance in described sliding die.
Above-mentioned adjusting device comprises the seat tube that is fixed on support, be arranged at screwed hole in seat tube, be vertically combined on the screw rod in seat tube screwed hole and be installed on the Connection Block in sliding die, and the lower end of described screw rod is rotated and is installed in Connection Block.
Above-mentioned gap adjusting device comprises the nut that is installed in sliding die, is combined on the bolt in nut, and the lower end of described bolt is provided with conical conehead.
For simple operation, the upper end of above-mentioned screw rod is laterally fixed with cross bar.
The invention has the beneficial effects as follows: will need the pipe I of butt welding to be placed on the arc of fixed die with pipe II, by adjusting device, drive sliding die to move down afterwards, arc and the arc on fixed die finally realized in sliding die will be managed I and manage II clamping and fix, because the axis of each arc in fixed die and sliding die coincides, therefore fixing pipe I with manage II and can guarantee coaxial.The alignment clearance with pipe II by gap adjusting device adjustment pipe I, makes it adjust to the required satisfied rational position of welding afterwards, can carry out butt welding to pipe I and pipe II afterwards.Therefore by this station boiler pipeline mouth of pipe welding alignment clearance positioner, can meet fast pipe is carried out to coaxial quick-clamping, can conveniently adjust alignment clearance again, simple to operate, improved operating efficiency.

In figure, 1. support 2. fixed die 3. sliding die 4. arc 5. Connection Block 6. screw rod 7. cross bar 8. nut 9. bolt 10. pipe I 11. are managed II 12. alignment clearance 13. conehead 14. seat tubes.
The specific embodiment
Below in conjunction with accompanying drawing 1, accompanying drawing 2, the present invention will be further described for accompanying drawing 3.
This station boiler pipeline mouth of pipe welding alignment clearance positioner, comprise fixed die 2, vertically be fixed on the support 1 on fixed die 2, by adjusting device can move up and down the sliding die 3 being fixed on support 1 and be installed on respectively fixed die 2 and sliding die 3 in some arcs 4, the axis of each arc 4 in described fixed die 2 and sliding die 3 coincides, fixed die 2 and sliding die 3 fix the pipe I 10 of two needs welding and pipe II 11 by arc 4, in described sliding die 3, be provided with for adjusting pipe I 10 and the gap adjusting device of managing II 11 alignment clearances 12.To need the pipe I 10 of butt welding to be placed on the arc 4 of fixed die 2 with pipe II 11, by adjusting device, drive sliding die 3 to move down afterwards, the arc 4 of finally realizing in sliding die 3 will be managed I 10 with the arc 4 on fixed die 2 and manage II 11 clampings and fix, because the axis of each arc 4 in fixed die 2 and sliding die 3 coincides, therefore fixing pipe I 10 with manage II 11 and can guarantee coaxial.The alignment clearance 12 with pipe II 11 by gap adjusting device adjustment pipe I 10, makes it adjust to the required satisfied rational position of welding afterwards, can carry out butt welding to pipe I 10 and pipe II 11 afterwards.Therefore by this station boiler pipeline mouth of pipe welding alignment clearance positioner, can meet fast pipe is carried out to coaxial quick-clamping, can conveniently adjust alignment clearance 12 again, simple to operate, improved operating efficiency.
Adjusting device can be for following structure it comprise the seat tube 14 that is fixed on support 1, be arranged at screwed hole in seat tube 14, be vertically combined on the screw rod 6 in seat tube 14 screwed holes and be installed on the Connection Block 5 in sliding die 3, the lower end of described screw rod 6 is rotated and is installed in Connection Block 5.By rotary screw 6, can make the relative seat tube 14 of screw rod 6 move up and down, thereby drive sliding die 3 to move down by Connection Block 5, final realization clamps fixing by pipe I 10 and pipe II 11.Simple in structure, convenient manufacture.
As shown in Figure 3, gap adjusting device can be for following structure it comprise the nut 8 that is installed in sliding die 3, be combined on the bolt 9 in nut 8, the lower end of described bolt 9 is provided with conical conehead 13.After the pipe I 10 of needs welding and pipe II 11 being clamped with sliding die 3 by fixed die 2, swivel bolt 9, makes the conehead 13 Inserting Tube I 10 of bolt 9 lower ends and alignment clearance 12 places between pipe II 11.Because conehead 13 is conical, therefore in the process that is inserted into alignment clearance 12, can gradually the width of alignment clearance 12 be increased, realized the object of progressively adjusting, convenient to operation.
The upper end of screw rod 6 can laterally be fixed with cross bar 7.By the light rotary screw 6 of cross bar 7, improved comfort.
