Abstract
The utility model relates to a butt-welding assembly for a container component with an assembling demand on upper and lower flanges, which comprises a lower positioning plate (1), an upper positioning plate (3), a cylindrical skeleton (2) and a resisting bolt (4), wherein the cylindrical skeleton (2) is connected with the lower positioning plate and the upper positioning plate; the resisting bolt (4) is located on the upper positioning plate; the butt-welding assembly is characterized in that a bottom centering base is arranged on the lower positioning plate; and the upper positioning plate is also provided with a bottom centering base which is coaxial with the lower positioning plate. The butt-welding assembly can be used for welding the container component with the demand on welding the upper and lower flanges in a coaxial parallel form; under the condition of less processing and even no processing, the coaxial and parallel upper and lower flanges can be ensured; and compared with a manufacturing method of utilizing the mechanical processing to ensure the coaxial and parallel upper and lower flanges after a welding process, the butt-welding assembly has the advantages that the material is saved, the processing time is saved and the manufacturing cost is comprehensively saved.
Description
Technical field
The utility model relates to a kind of pressure vessel technological equipment for making, especially welding frock.
Background technology
The long-term dirt of our company produces a kind of a kind of pressure vessel that is applied in the nuclear power serial equipment.This pressure vessel integral body is the dock structure, and wherein the first half is called " going up the chamber ", and Fig. 1 is " going up the chamber " structural representation, and it is by lower flange 11, cylindrical shell 12. butterfly end sockets 13 and butterfly end socket opening flange-upper flange 14 compositions such as grade.Specification requirement is: the upper flange inner diameter d requires coaxial with the lower flange inside diameter D; Upper flange plane Y requires parallel with the lower flange plane X; The flat requirement of the Y2 face of upper flange is parallel with the Y face; The outside diameter d 2 of upper flange requires and 4 specification requirements of the coaxial grade of inner diameter d.In order to reach above-mentioned 4 specification requirements, common manufacturing approach is, the lower flange finish turning to size and the cylindrical shell of the burn-oning butterfly end socket of burn-oning; All stay allowance to rough turn 4 faces of upper flange, wait to accomplish manual welding after, be benchmark with the inside diameter D and the plane X of lower flange; Vehicle Processing upper flange inner diameter d, outside diameter d 2, last plane Y2; Four faces such as lower plane Y can satisfy above-mentioned 4 specification requirements.But, done two shortcomings like this, 1. because allowance all will be stayed in the upper flange four sides, so material consumption is too many; 2. because the upper flange four sides all will process, so machining period expends too much.
Summary of the invention
In order to overcome the shortcoming that goes up the above-mentioned manufacturing approach in chamber, the utility model provides a kind of welding frock, uses this frock welding upper flange can not only reach 4 specification requirements, also can reduce material consumption, reduces machining period.
The utility model solves the technical scheme that its technical problem adopted: a kind ofly be used for the container member welding frock that lower flange has matching requirements; By following location-plate (1); Last location-plate (3) connects the awl tubular skeleton (2) of upper and lower location-plate and is positioned at the puller bolt compositions such as (4) on the location-plate, it is characterized in that: the centering benchmark that a backing is arranged on the following location-plate; Its centering face of cylinder diameter is D ', and X ' is vertical with the support face; Centering benchmark with the coaxial backing of following location-plate is arranged on the last location-plate, and its centering face of cylinder diameter is that d ' is vertical with support face Y '; Plane X ' vertical range of Y ' is h ' to the plane; D ', three sizes of d ' and h ' are coincide respectively with by the corresponding size of the relevant position of group welding piece.Use this assembly welding frock; Earlier being welded earlier to size and with cylindrical shell, butterfly end socket by the lower flange finish turning of group welding piece; Postwelding is installed to it on location-plate under the assembly welding frock (1) X ' face, arrives size to three finish turnings again, and the upper flange group that only top (Y2) stays allowance is on location-plate (3) Y ' face on frock; Hold out against upper flange with puller bolt (4) and plain clamp and to be clamped on the location-plate.Postwelding need not be processed other three, only processes that (Y2) just can reach 4 specification requirements above the upper flange.
The beneficial effect of the utility model is, goes up the chamber with this frock assembling welding, can not only guarantee 4 specification requirements, and save material, saves machined man-hour, comprehensively reduces manufacturing cost more than 20%.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is pressure vessel member " upward chamber " structural representation that needs with the utility model welding.
Fig. 2 is the utility model example structure sketch map.
11 lower flanges among Fig. 1,12 cylindrical shells, 13 butterfly end sockets, 14 upper flanges.
1 time location-plate among Fig. 2,2 awl tubular skeletons, location-plate on 3,4 puller bolts, A is by the last chamber relative position sketch map of welding.
The specific embodiment
At Fig. 2, lower flange among Fig. 1 (11) inside diameter D and the little matched in clearance of following location-plate (1) centering face of cylinder diameter D ' employing are so that centering and installation.Upper flange (14) inner diameter d and last location-plate (3) the centering face of cylinder matched in clearance that diameter d ' employing is bigger are slightly measured gap during centering, hold out against with the puller bolt level, and postwelding unclamps bolt is convenient to withdraw from frock.
Claims (1)
1. one kind is used for the container member welding frock that lower flange has matching requirements; By following location-plate (1); Last location-plate (3) connects the awl tubular skeleton (2) of upper and lower location-plate and is positioned at puller bolt (4) composition on the location-plate, it is characterized in that: the centering benchmark that a backing is arranged on the following location-plate; Its centering face of cylinder diameter is D ', and X ' is vertical with the support face; Centering benchmark with the coaxial backing of following location-plate is arranged on the last location-plate, and its centering face of cylinder diameter is d ', and Y ' is vertical with the support face; Plane X ' vertical range of Y ' is h ' to the plane; D ', three sizes of d ' and h ' are coincide respectively with by the corresponding size of the relevant position of group welding piece.
