Description

Shell ring plate welding tooling
Technical field
The utility model relates to metalwork auxiliary welding equipment technical field, particularly relates to a kind of shell ring plate welding tooling.
Background technology
The effect of shell ring is to provide the pressure-bearing space needed for technique, and be one of topmost pressure parts of pressure vessel, its interior diameter and volume often need to be determined by technology Calculation.Cylindrical shell ring (i.e. cylinder) and spherical shell ring are shell ring structures the most frequently used in engineering.Time shell ring diameter less (being generally less than 500mm), cylinder can make of seamless steel pipe, now shell ring does not have longitudinal seam; When diameter is larger, available steel plate is rolled into cylinder or on hydraulic press, is pressed into two semicircular cylinders with steel plate on veneer reeling machine, both is being welded together with weld seam, forms full circle cylinder.Because the longitudinal direction (namely axially) of the direction of this weld seam and cylinder is parallel, is therefore called longitudinal seam, is called for short longitudinal seam.If the diameter of container is not very large, generally only has a longitudinal seam; Along with the increase of container diameter, due to the restriction of steel plate book size, two or more longitudinal seam may be had.
In addition, the shorter container of length directly can connect end socket at the two ends of a cylinder, forms a closed pressure space, has also just made a pressure vessel enclosure.But when container is longer, due to the restriction of steel plate book size, also just need first to be welded into some sections of shell rings (a certain section of shell ring is called a shell ring) by roll of steel plate, then become the shell ring of Len req by two or more shell ring assembly welding.Attachment weld between shell ring and shell ring, between shell ring and end cap, because its direction is axially vertical with shell ring, is therefore called circumferential welded seam, is called for short girth joint.
When welding the shell ring of oversize, need that shell ring is divided into polylith to weld, owing to there is error between shell ring plate, when docking between shell ring plate with shell ring plate, the phenomenon of excesssive gap and misalignment between shell ring plate can be there is, need to adjust shell ring plate, but the precision of manual setting is lower and labour intensity is comparatively large, is not suitable for using in large-sized shell ring manufacturing process.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of shell ring plate welding tooling, described frock adopts two two-way leading screws and miscellaneous part combination, can correct the gap between shell ring plate and unfitness of butt joint simultaneously, facilitate the docking between shell ring plate, increase work efficiency, reduce labour intensity.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of shell ring plate welding tooling, it is characterized in that: described frock comprises the first clamping seats, first fishbolt, first connecting plate, first two-way leading screw, second clamping seats, second fishbolt, second connecting plate and the second two-way leading screw, described first clamping seats and the second clamping seats are U-shaped, described first fishbolt is threaded with the first clamping seats, described first clamping seats is fixed on one end of the first connecting plate, the other end of described first connecting plate is fixed with the first feed screw nut, match with described first feed screw nut in one end of first two-way leading screw, second feed screw nut's axle is connected to one end of the second connecting plate, described second clamping seats is fixed on the other end of the second connecting plate, described second fishbolt is threaded with the second clamping seats, the middle part axle of described first connecting plate is connected with the 3rd feed screw nut, the middle part axle of described second connecting plate is connected with the 4th feed screw nut, match with the 3rd feed screw nut in one end of described second two-way leading screw, the other end of described second two-way leading screw matches with the 4th feed screw nut.
Preferred technical scheme is further: described second connecting plate is L-type plate.
Preferred technical scheme is further: be equipped with gusset between described first clamping seats and the first connecting plate and between the second clamping seats and the second connecting plate.
Preferred technical scheme is further: described first fishbolt and the second fishbolt are throat bolt.
The beneficial effect adopting technique scheme to produce is: described frock adopts two two-way leading screws and miscellaneous part combination, can correct the gap between shell ring plate and unfitness of butt joint simultaneously, facilitate the docking between shell ring plate, increase work efficiency, reduce labour intensity.
