Abstract

The utility model provides a frock for hydroecium girth welding, it relates to a welding frock. The utility model provides a welding precision and the complicated problem of frock operation that current hydroecium girth welding dress card frock is unable when guaranteeing the automatic argon arc welding of hydroecium. Including clamp plate, bottom plate, barrel, and a plurality of stud, the clamp plate is circular flat board, has seted up a plurality of through -holes on the clamp plate, a plurality of internal thread holes have been offered for ring shape to the bottom plate on the bottom plate, the through -hole unanimously sets up with internal thread also quantity, and every through -hole and an internal thread pore pair should set up, the one end of barrel and a terminal surface rigid coupling of bottom plate, and the hydroecium head passes through the stud rigid coupling between clamp plate and bottom plate. The utility model discloses a frock for hydroecium girth welding is used for the welding of hydroecium circumferential weld.

Description

A kind of frock for hydroecium girth welding
Technical field
The utility model relates to a kind of frock for hydroecium girth welding.
Background technology
Major-diameter thick-wall hydroecium when automatic tungsten plate argon arc welding in order to reduce welding capacity, need to output two groove, weld in hydroecium inner side and outer side, very strict to the required distance of workpiece to head in argonaut welding termination process, just there will be blow-out or tungsten inclusion phenomenon comparatively greatly if there is distance fluctuation, thus cause weld defect.At present, a set of hydroecium girth welding frock that is installed cannot ensure that argonaut welding connects precision, to ensure precision, then needs two cover frocks to change, complicated operation.
Utility model content
The utility model is solve existing hydroecium girth welding to be installed the welding precision of frock when cannot ensure that hydroecium argonaut welding connects and the problem of frock complicated operation, and then provides a kind of frock for hydroecium girth welding.
The utility model for solving the problems of the technologies described above adopted technical scheme is: for the frock of hydroecium girth welding, comprise pressing plate, base plate, cylindrical shell, and some studs, described pressing plate is circular dull and stereotyped, pressing plate offers some through holes, described base plate is annular, base plate offers some internal thread holes, through hole is consistent with internal thread hole quantity to be arranged, each through hole is corresponding with internal thread hole to be arranged, one end of cylindrical shell and an end face of base plate affixed, water chamber head is fixed between pressing plate and base plate by stud.
The beneficial effects of the utility model are:
Hydroecium is fixed between pressing plate and base plate by stud, ensure that the stability of hydroecium in welding process, is installed compared with frock with existing hydroecium girth welding, effectively raises the rotating accuracy of hydroecium during hydroecium welding;
Hydroecium by being once installed, can realize the welding to outer ring seam in hydroecium, and without the need to carrying out secondary upset, centering, be installed compared with frock with existing hydroecium girth welding, frock is simple to operate, effectively raises operating efficiency.
