Background technology
General thin cylinder is rolled into cylinder by sheet metal and forms thin cylinder by after joint welding.When processing the thinner and cylinder that length is larger of wall thickness, can not realize integrally formed with a block plate.Its technical process is generally the short cylinder being first rolled into some sections of equal diameters, and then short cylinder butt welding is combined into long cylinder.Short cylinder is spliced into long cylinder, prior art is vertically stacked together by two cylindrical sections, manual type is adopted to align annular weld bond, because wall thickness of cylinder is too thin and internal diameter is larger, be difficult to upper and lower cylindrical wall to align during mounted on top, need a people to use screwdriver to adjust two cylindrical section walls in welding process and make its consistency from top to bottom, another people implements welding, there is welding labour intensity large, the low problem with welding length consuming time of welding production efficiency.
Summary of the invention
The invention provides a kind of major diameter thin cylinder of the same race docking swollen support device of rotary welding, the welding labour intensity solving prior art existence is large, the low technical problem with welding length consuming time of welding production efficiency.
The present invention solves above technical problem by the following technical programs:
A kind of major diameter thin cylinder of the same race docking swollen support device of rotary welding, comprise concentric support annulus and taper three-legged support, the bottom of three legs of taper three-legged support is fixedly installed on the annulus end face of concentric support annulus at equal intervals radian, tapped vertical tube is fixedly installed between the top of three legs of taper three-legged support, the axis of vertical tube coincides together with the axis of concentric support annulus, the hypomere of screw rod is bolted with in the top tube chamber of vertical tube, rotating disc is fixedly installed on the top of screw rod, the epimere of push rod is movably set with in the tube chamber of the bottom of vertical tube, the bottom of screw rod is together with the top apical grafting of push rod, the herringbone hinge seat support of level is fixedly installed in the bottom of push rod, on concentric support annulus, interval 120 degree is provided with swollen strut passing hole, a swollen strut of level is respectively movably set with in each swollen strut passing hole, the inner of the swollen strut of level is provided with swollen stay hinge seat, each hinge seat of three hinge seats on herringbone hinge seat support is provided with an interior bearing pin, each interior bearing pin is hinged with a transmission rod all separately, the other end of transmission rod is hinged by outer bearing pin with the swollen stay hinge seat that the inner of the swollen strut of corresponding level is arranged, the swollen support arc of level is provided with in the outer end of the swollen strut of level, three level swollen support arcs form that level is swollen to be held round, the swollen axis held round of level be made up of three level swollen support arcs coincides together with the axis of concentric support annulus.
The lateral surface of swollen support arc is provided with anti-welding adhesion cannelure.
The present invention can meet the larger butt-welded needs of cylinder of the same race of the thinner bore of wall thickness, the rapid alignment of the barrel of two sections of cylinders of the same race can be realized, by rotating rotating disc, axial straight line external force is applied to push rod group, can realize the function that two cylindrical section edges fit tightly alignment fast, thus when solving large diameter and thin wall cylinder use traditional approach docking, barrel is out of shape the problem causing edge not easily to align.Improve the welding quality of cylinder butt girth welding seam, ensure that the axiality after docking, greatly accelerate welding production speed.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of major diameter thin cylinder of the same race docking swollen support device of rotary welding, comprise concentric support annulus 1 and taper three-legged support 2, the bottom of three legs of taper three-legged support 2 is fixedly installed on the annulus end face of concentric support annulus 1 at equal intervals radian, tapped vertical tube 3 is fixedly installed between the top of three legs of taper three-legged support 2, the axis of vertical tube 3 coincides together with the axis of concentric support annulus 1, the hypomere of screw rod 4 is bolted with in the top tube chamber of vertical tube 3, rotating disc 5 is fixedly installed on the top of screw rod 4, the epimere of push rod 6 is movably set with in the tube chamber of the bottom of vertical tube 3, the bottom of screw rod 4 is together with the top apical grafting of push rod 6, the herringbone hinge seat support 7 of level is fixedly installed in the bottom of push rod 6, on concentric support annulus 1, interval 120 degree is provided with swollen strut passing hole 15, a swollen strut 10 of level is respectively movably set with in each swollen strut passing hole 15, the inner of the swollen strut of level 10 is provided with swollen stay hinge seat 12, each hinge seat 8 of three hinge seats on herringbone hinge seat support 7 is provided with an interior bearing pin 9, each interior bearing pin 9 is hinged with a transmission rod 14 all separately, the other end of transmission rod 14 is hinged by outer bearing pin 13 with the swollen stay hinge seat 12 that the inner of the swollen strut of corresponding level 10 is arranged, the swollen support arc 11 of level is provided with in the outer end of the swollen strut of level 10, three level swollen support arcs 11 form that level is swollen to be held round, the swollen axis held round of level be made up of three level swollen support arcs 11 coincides together with the axis of concentric support annulus 1.
The lateral surface of swollen support arc 11 is provided with anti-welding adhesion cannelure 16, before welding during two sections of short cylinder alignment, the annular weld bond of two short cylinder splicings is arranged on the anti-welding adhesion cannelure 16 that the lateral surface of swollen support arc 11 is arranged, welding fluid can not be sticked together with the lateral surface of swollen support arc 11.
The present invention, by rotating rotating disc 5, makes it produce axial movement thus promotes push rod 6 to move; When push rod 6 moves down, three hinge seats 8 on the herringbone hinge seat support 7 of its bottom also move down, power is converted to the extrapolability radially of level by each hinge seat 8 by transmission rod 14, namely push rod 6 move up and down the radial motion changing the swollen strut of level 10 and the swollen support arc 11 of level into, three level swollen support arcs 11 form that level is swollen to be held round, and realize the swollen support function to two sections of welding drums.The distance of stretch out and draw back of level of the present invention is swollen strut can reach more than 20 millimeters, can meet the butt welding requirement that barrel has the thin cylinder of the same type of the particular inside diameters of certain distortion.First, make two butt welding cylinder horizontal positioned, end contact, first swollen support end is loaded cylinder interior, make the swollen support arc 11 of level be positioned at the weld bond position of two cylindrical sections, then rotate rotating disc 5 and make three level swollen support arcs 11 form a swollen support diameter of a circle of level to strengthen gradually.Swollen for the level external diameter that holds round is expanded to two cylindrical section joints are combined closely and concordant time, stop applying external force.To guarantee that the seam of two cylindrical sections is positioned on anti-welding adhesion cannelure 16 that the lateral surface of swollen support arc 11 is arranged simultaneously, then weld at cylinder seam crossing.
