Description
Technical field
The utility model relates to a kind of device of measuring cylindrical shell two ends flange coaxial degree, belongs to detection technique field.
Background technology
After the flange welding at cylindrical shell two ends, due to factors such as part tolerance accumulation and welding deformations, the flange at two ends there will be the situation of decentraction conventionally, and especially some major diameters, more piece assembly welding arrive ultra-long barrel together, and axiality is poorer. Because flange is hollow work-piece, its position, center of circle does not have entity to locate, so axiality cannot directly be measured, up to the present also there is no a set of measuring method accurately and efficiently and device.
Utility model content
The utility model object is to provide a kind of device of measuring cylindrical shell two ends flange coaxial degree, and equipment is simple, cheap, and flexible operation solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of device of measuring cylindrical shell two ends flange coaxial degree, comprise center of circle positioning tool, steel wire and tensiometer, center of circle positioning tool is strip shape body, length is greater than the diameter of cylindrical shell, center has centre bore, on the strip shape body of centre bore both sides, symmetry has flange connecting hole, and the flange hole on position and the end face of flange of flange connecting hole matches; Center of circle positioning tool is fixed in cylindrical shell one end flanges by flange connecting hole and flange hole, and steel wire one end is fixed on the centre bore of center of circle positioning tool, and the other end is moved opposite flange to through inner barrel, ties up on the hook of tensiometer.
Described center of circle positioning tool, on the strip shape body of centre bore both sides, symmetry has multipair flange connecting hole, adapts to the flange of different-diameter.
Cylindrical shell two ends be respectively equipped with left end flange and right-hand member flange; Use bolt center of circle positioning tool to be fixed on by flange connecting hole and flange hole on the left end flange of cylindrical shell, on the right-hand member end face of flange circumference of cylindrical shell, mark respectively eight equal parts point; Steel wire one end is fixed on the centre bore of center of circle positioning tool, the other end is moved opposite right-hand member flange to through inner barrel, ties up on tensiometer hook; In eight equal parts point mark, use same value of thrust taut wire respectively, on steel wire, mark one by one the position overlapping with any Along ent, on steel wire, obtain eight marks; Ultimate range on steel wire between two marks, is approximately cylindrical shell two ends flange coaxial degree.
The beneficial effects of the utility model are: center of circle positioning tool can accurately be determined the flange center of circle, multipair connecting hole on the positioning tool of the center of circle, applicable to different-diameter flange, uses same value of thrust tension finer wire can avoid measure error while measuring eight equal parts position coincide point; Easy to carry, easy and simple to handle, be suitable in factory and the different work occasion such as field.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model center of circle positioning tool schematic diagram;
In figure: left end flange 1, center of circle positioning tool 2, steel wire 3, cylindrical shell 4, right-hand member flange 5, end face of flange Along ent 6, tensiometer 7, measurement coincide point 8, flange connecting hole 9, centre bore 10.
Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
A kind of device of measuring cylindrical shell two ends flange coaxial degree, comprise center of circle positioning tool 2, steel wire 3 and tensiometer 7, center of circle positioning tool 2 is strip shape body, length is greater than the diameter of cylindrical shell 4, center has centre bore 10, on the strip shape body of centre bore both sides, symmetry has flange connecting hole 9, and the flange hole on position and the end face of flange of flange connecting hole matches; Center of circle positioning tool 2 is fixed in cylindrical shell one end flanges by flange connecting hole and flange hole, and steel wire 3 one end are fixed on the centre bore 10 of center of circle positioning tool, and the other end is moved opposite flange to through inner barrel, ties up on the hook of tensiometer 7.
Described center of circle positioning tool, on the strip shape body of centre bore both sides, symmetry has multipair flange connecting hole 9, adapts to the flange of different-diameter.
With reference to accompanying drawing 1,2, a kind of device of measuring cylindrical shell two ends flange coaxial degree, comprises center of circle positioning tool 2, steel wire 3, tensiometer 7, and steel wire 3 one end are fixed on centre bore 10 places of center of circle positioning tool 2, and the other end catches on tensiometer 7. On center of circle positioning tool 2, have centre bore 10 and multipair flange connecting hole 9.
Use bolt through the connecting hole 9 on center of circle positioning tool 2, be fixed on cylindrical shell left end flange 1, on the right-hand member flange 5 end face circumference of cylindrical shell 4, mark eight end face of flange Along ents 6; Steel wire 3 one end are fixed on center of circle positioning tool centre bore 10, and the other end is moved right-hand member flange 5 places, opposite to through cylindrical shell 4 inside, ties up on tensiometer 7 hooks; At eight equal parts point E place, use fixing value of thrust L taut wire, the measurement coincide point 8 at mark steel wire and E place on steel wire; Use same steps on finer wire, to mark other several Along ent coincidences position, the distance on finer wire between 2 marks of outermost is approximately cylindrical shell two ends flange coaxial degree.
