Abstract

The invention provides a pipe centering assembly platform. Coaxial semi-circular supports longitudinally aligned are distributed on the platform, and two radial scale bolts pointing to the axes of the supports are arranged on each support. The pipe centering assembly platform is suitable for various pipe diameter matching conditions, particularly the accurate centering of large pipes, is simple to operate, convenient to disassemble and convenient to carry, improves the work efficiency and ensures the pipe assembly quality.

Description

Pipe fitting centering assembly or fitting table
Technical field
The present invention relates to a kind of pipe fitting centering assembly or fitting table, belong to machinery manufacturing technology field.
Background technology
In the manufacture process of various electromechanical equipment, often relate to the assembling between various pipe fitting.Owing to considering the factor such as know-why, design cost, instructions for use in design process, coordinate between such as, caliber shown in Fig. 1 and just may there is multiple situation: (1) D=dH>h or H<h; (2) D>d or D<dH=h; (3) D>dH>h; (4) D>dH<h; (5) D<dH<h; (6) D<dH>h; (7) D=dH=h.This brings difficulty with regard to giving the centering in assembling process between pipe fitting.During on-the-spot pipe fitting assembling, such as, butt welding between pipe fitting, owing to not having suitable centralising device, often relies on the experience of welding personnel only to judge to carry out centering welding with naked eyes.Because method is rigorous not, centering effect is very unreliable, and in welding process, skew easily appears in interface tube end face, and throat depth is uneven, causes weld strength uneven.In use, channel interior pressure drag easily produces sudden change, occurs tearing, touching disconnected, leakage, and weld seam weak location even there will be the phenomenons such as explosion.The applicant proposes a kind of pipe fitting welding centralising device in application publication number CN104057234A, utilize cooperatively interacting of auxiliary body and left and right auxiliary block, accurate centering when making pipe and flange welding, especially pipe fitting internal diameter is greater than the cooperation of flange inner diameter, not only even weld, and after assembling be easy to centralising device to remove.But the centering of situation about coordinating for multiple caliber particularly large-size pipe, still needs the pipe fitting assembling centering scheme that a kind of adaptability is stronger, operation is more simple and easy to do.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of pipe fitting centering assembly or fitting table.
The object of the present invention is achieved like this: a kind of pipe fitting centering assembly or fitting table, comprises a platform, it is characterized in that coaxial semi-circular seatings platform being furnished with longitudinally alignment, each bearing is arranged the radial scale bolt in two sensing bearing axle center.
In order to better realize object of the present invention, described platform is provided with the slideway for bearing location, slideway is furnished with locating hole, bearing can be fixed on slideway by alignment pin.
In order to realize object of the present invention better, arrange a semicircle flap isometrical with bearing above described each bearing, the two ends of flap are docked with bearing by fastening bolt, flap are arranged the radial scale bolt that is pointed to axle center downwards.
In order to realize object of the present invention better, one end that one end of described flap can be corresponding to bearing is hinged.
In order to realize object of the present invention better, the inner that described radial scale bolt points to axle center is provided with roller.
Technical scheme of the present invention, be applicable to the accurate centering of various caliber mated condition especially large-size pipe, simple to operate, easy accessibility, is easy to carry, and improves work efficiency, ensure that the quality that pipe fitting is assembled.
