Abstract
The utility model provides a general tool for automatic welding of a large pressure vessel saddle type connection pipe. The general tool for the automatic welding of the large pressure vessel saddle type connection pipe comprises a centre plate, four sliding plates and hinge pins. The sliding plates are provided with oblong holes, the centre plate is provided with oblong holes which match with the oblong holes on the sliding plates, outer diameters of the hinge pins match with the oblong holes on the sliding plates, and the hinge pins and the oblong holes on the sliding plates are fixed through bolts and nuts. A saddle type connection pipe automatic welder is widely used in the large pressure vessel manufacturing industry to weld a large diameter connection pipe, but a middle diameter of a large connection pipe flange is usually larger than that of a base seat of the saddle type connection pipe automatic welder in practice so that use of the saddle type connection pipe automatic welder is seriously limited. The size of the general tool for the automatic welding of the large pressure vessel saddle type connection pipe can be changed according to different sizes of diameters of center holes of flanges, inner diameters of hinge pins 3 are in various specifications in order to match with diameters of bolt holes of different flanges, and therefore demands of production diversity can be met. The general tool for the automatic welding of the large pressure vessel saddle type connecting pipe has the advantages of being strong in operability and convenient to assemble and disassemble, and design demands of strength and rigidity can be met.
Description
Technical field
The utility model is applicable to the welding that the large pressurized vessel saddle-shape is taken over.
Background technology
Using saddle-shape to take over automatic welder(welding machine) welds the major diameter adapter of diameter >=350mm; Be widely used in the large pressurized vessel manufacturing industry at present; But, saddle-shape is about about 350mm because taking over the base diameter of automatic welder(welding machine); And the footpath has seriously restricted the use of the automatic welded pipe welding machine of saddle-shape often all greater than 350mm in the large-scale pipe connecting flange.Therefore the flange of every kind of specification all must prepare a traditional welding tooling (see figure 4) according to the size of its ring flange and the size in flange bolt hole in the Lincoln weld termination process that major diameter is taken over, and is very serious to the waste of material.To choose suitable plate earlier during use; Cut off gripper shoe with the numerical control blanking then; Bolt hole on it also to use drilling machine or boring machine processing, the adapter of each Lincoln weld all will be carried out the operation of above-mentioned steps, if just the delay time at stop can influence next step welding; And owing to these frocks all are deposited in together, even other product has the identical flange of specification to ransack also very difficulty.
Summary of the invention
The purpose of the utility model is a kind of general frock of invention, solves the problems referred to above that prior art exists, with many-sided requirement such as satisfy economical with materials, conveniently produce, increase work efficiency.
The utility model provides a kind of large pressurized vessel saddle-shape to take over the general frock of welding automatically, mainly comprises 2, four slide plates 1 of central plate and bearing pin 3; Be processed with slotted hole on the described slide plate 1; Being processed with slotted hole on the described central plate 2 cooperates with slotted hole on the described slide plate 1; Described bearing pin 3 external diameters cooperate with slotted hole on the slide plate 1; Fix through bolt, nut, the internal diameter of bearing pin 3 has plurality of specifications to cooperate the diameter of bolt hole of different flanges; Described central plate 2, slide plate 1 and bearing pin 3, material is Q235A; Described slide plate 1 machining accuracy is 0.3-0.5 mm, and length is 650mm, and thickness is 40mm; Be carved with relative position and the center processing circular hole of graduation mark on the described central plate 2, in order to the saddle-shape automatic welder(welding machine) to be installed in order to confirm this frock and flange.
Technique scheme has following advantage:
1. this frock can varying in size and change self size with the center-hole diameter of different flanges;
2. the diameter of bolt hole of different flanges is different, and bearing pin 3 internal diameters of the utility model have plurality of specifications, can satisfy the requirement of product diversity;
3. this frock is workable, is convenient to installation and dismounting and intensity, rigidity meets design requirement.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done following description:
Referring to the Fig. 1 in the accompanying drawing, Fig. 4, the utility model provides a kind of large pressurized vessel saddle-shape to take over the general frock of welding automatically, mainly comprises 2, four slide plates 1 of central plate and bearing pin 3; Be processed with slotted hole on the described slide plate 1; Being processed with slotted hole on the described central plate 2 cooperates with slotted hole on the described slide plate 1; Described bearing pin 3 external diameters cooperate with slotted hole on the slide plate 1; Fix through bolt, nut, the internal diameter of bearing pin 3 has plurality of specifications to cooperate the diameter of bolt hole of different flanges; Described central plate 2, slide plate 1 and bearing pin 3, material is Q235A; Described slide plate 1 machining accuracy is 0.3-0.5 mm, and length is 650mm, and thickness is 40mm; Be carved with relative position and the center processing circular hole of graduation mark on the described central plate 2, in order to the saddle-shape automatic welder(welding machine) to be installed in order to confirm this frock and flange.
One of specific embodiment: the diameter of Fig. 1 central plate 2 in the accompanying drawing is φ 1200mm; At the external diameter of pipe connecting flange greater than 300mm during smaller or equal to 1200mm; Four slide plates 1 are removed; Central plate 2 is positioned on the pipe connecting flange, chooses 4 suitable bearing pins 3, bearing pin 3 is put in the bolt hole of slotted hole and flange of central plate 2 according to the size in flange bolt hole; With bolt and nut that the three is fixing after tight, the slotted hole of central plate 2 and the outer surface of bearing pin adopt tolerance fit to prevent owing to excesssive gap is swung.With its jaw means that carries the saddle-shape automatic welder(welding machine) is fixed on the central plate 2 near saddle-shape being taken over the centre bore of automatic welder(welding machine) centering plate 2, the adjustment orientation just can be welded.
Two of the specific embodiment: at the external diameter of pipe connecting flange during greater than 1200mm; Then need measure the diameter of a lower flange; On the ground that 4 slide plates 1 are first with hanging on ring flange with crane after the bolt with central plate 2; The outward flange that guarantees 4 slide plates 1 simultaneously equates with the outward flange of central plate distance, utilizes graduation mark adjustment central plate 2 and the position of ring flange on the central plate 2, and central plate 2 centers are overlapped with the ring flange center; The distance that fine setting central plate 2 and 4 slide plates are 1 makes the center of the slotted hole of slide plate 1 overlap with the center of pipe connecting flange bolt hole.Referring to the Fig. 1 in the accompanying drawing and Fig. 4, at this moment bearing pin 3 is placed the slotted hole and the bolt holes of (for) nozzle flange of slide plate 2, with bolt that bearing pin 3 is fixing.The saddle-shape automatic welder(welding machine) is fixed on the central plate 2, and the adjustment orientation just can be welded.
