The automatic Clamp for welding of the design's bellows half-wave welding, solved effectively in the prior art to flange bolt hole, two ends require tight, weld appearance is fair, weld seam is positioned at the technical barrier of bellows straight section, have reasonable in design, loading and unloading easily, and are easy to operate, appearance of weld is good, save time, laborsaving, labour intensity is low, the characteristics that welding efficiency is high.Through repetition test, succeed in developing at home, and reached the advanced level of international like product, wherein be welded as critical process, must satisfy weld strength, the requirement of presentation quality and flange bolt hole axiality.
Description of drawings
Fig. 1 is that the bellows half-wave welds automatic Clamp for welding structural representation;
The specific embodiment
The automatic Clamp for welding of a kind of bellows half-wave welding; see Fig. 1: comprise bottom deck assembly; the gentle guarantor's assembly of cover assembly; it is characterized in that: big alignment pin 7 and central shaft 8 two ends and bottom deck assembly 5 and cover assembly 15 assemblings support the space of bellows 13 to be welded; two assembly outer rims are fixed flange 10 to be welded respectively in opposite directions; the stage casing is provided with gas and protects the overcoat 12 gentle guarantors of assembly and encircle 20 bellows 13 is clipped between bottom deck assembly 5 and the cover assembly 15; clamp whole jig by nut 18; under gas is protected the protection of assembly and is supported; jig rotation under deflection machine drives; argon-arc welding gun 11 starts, and finishes whole weld job automatically.
Bottom deck assembly 5 and cover assembly 15 are welded with locating ring 6, periphery respectively, and hole, the circle centre position of putting little alignment pin 9 are arranged is spindle hole and big dowel hole, locating ring 6 in opposite directions and have living space, circle centre position central shaft 8, three big alignment pins 7 and positioning disk 16 are fixing therebetween, the center axle head that the spindle end in cover assembly 15 outsides is loaded onto packing ring 17, the two assemblies outside all has nut 18, fits tightly with the place to be welded that guarantees bellows 13 to be welded and flange to be welded 10,14.
Locating ring 6 is a tubulose, and its external diameter equates that with bellows 13 internal diameters bottom deck assembly 5 and cover assembly 15 opposite sides are welded with locating ring 6 respectively, on the bottom deck assembly 5, locating ring 6 is outer settles flanges 10 and have four circumferential little alignment pins 9 accurately fixing.Cover assembly 15 settles flange 14 identical with the mode of bottom deck assembly 5.
Bottom deck assembly 5 links to each other with bracing ring 3 by screw 4, and the journal stirrup 21 that is welded on the bracing ring 3 is fixed on the workbench 1 of deflection machine by bolt 2.Big alignment pin 7 and central shaft 8 closely cooperate with bottom deck assembly 5, non-dismountable, and connect into an integral body near a side of cover assemblies 15 by positioning disk 16 at equally distributed three the big alignment pins 7 of central shaft periphery, radially remain unchanged with circumferential position to guarantee relative between bottom deck assembly 5 and the cover assembly 15.
Place to be welded, bellows 13 two ends is provided with two gas and protects ring 20, is provided with in opposite directions, and the stage casing is provided with overcoat 12, and gas is protected ring 20 and overcoat 12, is two 180 ° semi-ring, and interlocking in twos is one group.Gas is protected the cross sectional shape of ring 20: the big footpath of semi-ring is less than overcoat 12, and the corner radian is consistent with the labyrinth of bellows external wave, and the path edge conforms to the bellows radial shape, enriches ripple in the bellows.
Each hole of little alignment pin 9 is set on bottom deck assembly 5 and the cover assembly 15, utilizes the drilling tool template of flange 10 bolts hole to process, to guarantee the positioning accuracy of alignment pin 9 and 19.
The operation principle and the operating procedure of this device are as follows
1, deflection machine workbench 1 is adjusted to horizontal level, the bracing ring 3 that is connected with bottom deck assembly 5 is fixed on the deflection machine workbench 1 by bolt 2.
