Abstract
The utility model relates to machining tooling equipment, in particular to a cast pipe and flange centering machine which comprises a left supporting plate and a right supporting plate. The cast pipe and flange centering machine is characterized in that two upper optical levers and two lower optical levers which are arranged horizontally are arranged on the left supporting plate and the right supporting plate; one ends of the four optical levers are provided with a vertical fixed template close to the supporting plate, while the other ends of the optical levers are provided with a vertical moving template which slides in the horizontal direction, and a plurality of positioning pins matched with welded flange bolt holes are arranged on two opposite surfaces of the fixed template and the moving template; and a left regulating support and a right regulating support which are used for supporting a processed cast pipe are also arranged. The utility model solves the problems of large error, large labor intensity, high required technical merit, and the like during welding and hot sleeving cast pipes and flanges manually and is mainly used for welding processes of cast iron pipes and flanges.
Description
(1) technical field: the utility model relates to the machining tooling device, is to be used for a kind of cast tube flange transducer that cast iron pipe and flange welding processing are used.
(2) background technology: be used for long distance water transfer or carry the pipeline of other medium, requiring that rear line is installed should be straight, and the sealing joint performance will be got well.If excessive for the pipeline two parallel flange deviations that flange connects, the situation as Fig. 1 will appear, as can be seen from the figure, and the uneven pipe of two flanges, pipeline can not be installed by straight line, pipeline deflection, angle appears in flange sealing surface.In this case, pipeline can be dressed up snakelike, has both influenced the water delivery effect, has increased pipeline again and has taken up an area of and operating expenses, and this is definitely unallowable.Even more serious is that interface can leak after angle appearred in two flanges, if the clamp flange bolt that transfinites is proofreaied and correct the sealing surface gap, probably causes flange and the drawing crack of body weld bond and great quality accident occurs.
Welding double plate flanged pipe has a lot of bolts hole on the flanged pipe, according to flange (DN value) different with pressure rating (the PN values) that vary in size, the diameter of flange hole is also different with quantity.When flange and body welding, the center of two flange holes must align, and not so is connected the mutual deflection of pipe fitting on the pipeline, and tap line can't be installed.The assembling of hot jacket method is normally adopted in cast tube and flange welding, promptly earlier flange is heated to uniform temperature.Again with cast tube assembling, welding.Flange and cast tube adopt interference fit.Assembling back two flange nonparallelism tolerances are ± 1.5mm.Flange hole nonconcentricity tolerance is ± 1.5mm.Domestic traditional hot charging method of completing the square is to adopt the method for " manually going offline " at present, and main detection method is to utilize face plate to detect.This assembly method not only the time long, and it is more influenced by human factors such as technical merit, working sense of responsibility, so rigging error is bigger, can not satisfy the demand of batch process.
(3) summary of the invention: the purpose of this utility model will solve manually-operated cast tube and the assembling of flange sweating heat cover exactly, and labour intensity is big, and the working time is long, and rigging error is big, requires the high problem of technical merit, and a kind of cast tube flange transducer is provided.
Concrete scheme of the present utility model is: design left and right sides support plate, it is characterized in that: horizontally disposed each two feed rod up and down are installed on the supporting plate of the left and right sides, end at four feed rods is equipped with vertically arranged fixed form near supporting plate, the other end at feed rod is equipped with the moving platen that is arranged vertically the horizontal direction slip, and on fixed form and moving platen two opposite faces, be provided with the some alignment pins that match with the flange bolt hole that is welded; The left and right adjusting supporting of the processed cast tube of supporting is equipped with and.
The two ends of upper and lower feed rod described in the utility model are processed with screw thread, and adopt nut to fixedly connected with left and right sides supporting plate.
For guarantee the accurate positioning of moving platen, the fairlead that the utility model is welded and cooperates with polished rod on described moving platen.
Regulating supporting described in the utility model, is to be made of v block, adjusting screw mandrel and cushion block.
For the welding assembling of big cast tube and flange, the utility model can also change hydraulic drive into by artificial promotion at moving platen one end.
The utility model is simple in structure, and is easy to operate, quick, the assembly precision height, and equipment interoperability is strong, and can satisfy production demand.
(4) description of drawings:
Fig. 1 is the not parallel pipeline state diagrams of cast tube two end flanges;
Fig. 2 is a front view of the present utility model;
Fig. 3 is the A-A view of Fig. 2.
Among the figure: 1-left socle plate, the 2-fairlead, the 3-moving platen, the 4-alignment pin, 5-left side flange, the 6-polished rod, the 7-cast tube, the right flange of 8-, the 9-fixed form, 10-right support plate, 11, the 12-nut, the 13-V sections, 14-regulates screw mandrel, 15-cushion block.
(5) specific embodiment:
Referring to Fig. 2, Fig. 3, the utlity model has left and right sides supporting plate 1 and 10, particularly: horizontally disposed each two feed rod 6 up and down are installed on left and right sides supporting plate 1,10, and polished rod 6 two ends are processed with screw thread, adopt nut 11,12 to fixedly connected with 10 with left and right sides supporting plate 1.Right-hand member at four feed rods 6 is equipped with vertically arranged fixed form 9 near supporting plate 10, left end at feed rod 6 is equipped with the moving platen 3 that is arranged vertically the horizontal direction slip, and on fixed form 9 and 3 liang of opposite faces of moving platen, be provided with four alignment pins 4 that match with the flange bolt hole that is welded; And be equipped with the left and right adjusting supporting of the processed cast tube of supporting, every group is regulated supporting is by v block 13, regulates screw mandrel 14, and cushion block 15 is formed.
For guaranteeing the accurate positioning of moving platen 3, the fairlead 2 that the utility model is welded and cooperates with polished rod 6 on described moving platen 3 promptly constitutes the utility model.
Operation principle of the present utility model is: at first left and right sides flange 5 and 8 is enclosed within cast tube 7 two ends, again cast tube 7 is placed in the left and right adjusting supporting, by regulating screw mandrel 13 smoothings, pushing away right flange 8 is close to fixed form 9, and by alignment pin 4 location, adjust cast tube 7 and keep design attitude with right flange 8, the right flange 8 of spot welding is fixing with cast tube 7.Regulate left flange 5 and be close to moving platen 3, and by alignment pin 4 location, promote template 3, make left flange 5 and cast tube 7 keep design attitude, spot welding left side flange 8 is fixing with cast tube 7, can finish the assembling of flange and cast tube.
