Abstract
The utility model relates to a measure device of barrel both ends flange depth of parallelism belongs to and detects technical field. Technical scheme is: base (1) is big end down's round platform type structure, and base round platform (8) its end face centre rigidity has pull ring (9), and steel wire (3) one end is fixed on pull ring (9) of base (1), and tensiometer (5) is connected to the other end. It is downthehole to insert the barrel flange with the base, with steel wire one end system on the pull ring, the other end passes barrel (4), opposite flange hole and catches on tensiometer (5), correspond branch departments such as eight at two flanges and use the taut steel wire of same pulling force value, on the steel wire one by one the mark steel wire with etc. The coincident position of branch, two dot marks of outermost size within a definite time is depth of parallelism numerical value promptly. The beneficial effects of the utility model are that: it is simple and convenient effective, use same pulling force value to strain the steel wire when measuring eight partition position coincide points, can avoid measuring error, portable, simple and practical is suitable for different operation occasions such as interplant and field.
Description
Technical field
The utility model relates to a kind of device measuring cylindrical shell two ends parallel flange 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 uneven situation usually; especially some major diameters, many shell rings assembly welding are to ultra-long barrel together; the depth of parallelism is poorer, there will be crooked phenomenon after overall like this assembling.Background technology uses the method for the laser measurement depth of parallelism, and equipment manufacturing cost is expensive, complicated operation, is only applicable to high-precision applications occasion, can not meet convenient, measure requirement accurately and efficiently.
Utility model content
The utility model object is to provide a kind of device measuring cylindrical shell two ends parallel flange degree, and equipment is simple, cheap, flexible operation, measures accurately, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of device measuring cylindrical shell two ends parallel flange degree, comprise base, steel wire and tautness meter, base is up-small and down-big circular platform type structure, and its end face center of base round platform is fixed with draw ring, steel wire one end is fixed on the draw ring of base, and the other end connects tautness meter.
Described base round platform is welded with draw ring.
Cylindrical shell two ends be respectively equipped with left end flange and right-hand member flange, end face of flange has eight flange holes, the end face of left end flange and right-hand member flange marks eight equal parts point respectively, and the position of Along ent is exactly the central point of flange hole; Steel wire is passed simultaneously the Along ent of left end flange and right-hand member flange correspondence position; Base round platform diameter is inserted the flange hole of a side flange compared with small end, steel wire passes from inner barrel, passes the Along ent of left end flange and right-hand member flange correspondence position simultaneously; Steel wire one end is fixed on the draw ring of base, and the other end ties up on the hook of tautness meter; Respectively at eight pairs of Along ent index aperture places, use same value of thrust taut wire, and on steel wire, mark the position that to overlap with Along ent one by one, steel wire obtains eight marks; Ultimate range on steel wire between two marks, is namely approximately cylindrical shell two ends parallel flange degree.
The beneficial effects of the utility model are: simple and effective, and use same value of thrust taut wire when measuring eight equal parts position coincide point, can avoid measuring error, up-small and down-big base frustum cone structure can be applicable to different pore size flange.Be easy to carry, simple and practical, be suitable in factory and the different work occasion such as field.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model base schematic diagram;
In figure: base 1, left end flange 2, steel wire 3, cylindrical shell 4, tautness meter 5, right-hand member flange 6, end face of flange Along ent 7, base round platform 8, draw ring 9.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
A kind of device measuring cylindrical shell two ends parallel flange degree, comprise base 1, steel wire 3 and tautness meter 5, base 1 is up-small and down-big circular platform type structure, and its end face center of base round platform 8 is fixed with draw ring 9, steel wire 3 one end is fixed on the draw ring 9 of base 1, and the other end connects tautness meter 5.
Measure a method for cylindrical shell two ends parallel flange degree, comprise following steps:
With reference to accompanying drawing 1,2, a kind of device measuring cylindrical shell two ends parallel flange degree, comprises base 1, steel wire 3, tautness meter 5, and steel wire 3 one end is fixed on the draw ring 9 of base 1, and the other end catches on tautness meter 5.Base round platform 8 is welded with draw ring 9.
The left end flange 2 and right-hand member flange 6 of cylindrical shell 4 mark eight equal parts point 7 respectively, by steel wire 3 simultaneously through the Along ent C point of two the flange correspondence positions in left and right; Steel wire 3 passes from cylindrical shell 4 inside, and its one end is fixed on draw ring 9, base 1 taper end is inserted the C location hole of left end flange 2, and the steel wire other end passes the C location hole of right-hand member flange 6 and ties up on tautness meter 5 hook; Use fixing value of thrust L taut wire 3, steel wire 3 marks the position that to overlap with Along ent C, measures other Along ents such as two flange A-A, B-B, D-D by same method; Namely distance on steel wire 3 between outermost 2 mark is approximately cylindrical shell two ends parallel flange degree.
Claims (2)
