As shown in Figure 1, a kind of two-side synchronous tension mechanism for argon arc welding circular weld, including bearing 1, left cover
2nd, right cover plate 3, a left side rise block 4, the right side rise block 5, draw cone 6 and pressure cone 7；The bearing 1 is disc-shaped structure, the left cover 2 and the right side
Cover board 3 is cirque structure, and left cover 2 and right cover plate 3 are symmetrically packed in 1 both sides of bearing, and bearing 1, left cover 2 and right cover
Plate 3 is coaxially disposed；Some left sides are offered between the bearing 1 and left cover 2 to rise block installation pilot hole, bearing 1 and right cover plate 3 it
Between offer some right sides rise block installation pilot hole, the left side rise block installation pilot hole and the right side rise block installation pilot hole it is circumferentially equal
Cloth is set；A left side is mounted in the block that on each left side rises installation pilot hole to rise block 4, and 4 the inner of block of rising on a left side is provided with
Left power transmission roller 8；A right side is mounted in the block that on each right side rises installation pilot hole to rise block 5, and 5 the inner of block of rising on the right side is set
It is equipped with right power transmission roller 9；It is described to draw cone 6 and pressure cone 7 rises by block 4 with a left side respectively and the right side block 5 that rises synchronizes tensioner and coordinates.
6 points of the drawing cone is conehead and pull rod two parts, and the conehead for drawing cone 6 is circular cone structure, and pull rod is positioned at drawing cone 6
Conehead miner diameter end.
The pressure cone 7 is circular cone structure, and pull rod is offered at the center of pressure cone 7 and passes through hole, pressure cone 7 is passed through by pull rod
Hole is sleeved on the pull rod for drawing cone 6, and draws the miner diameter end face of the miner diameter end and pressure cone 7 of 6 coneheads of cone to set.
Offer through hole 10 at the center of the bearing 1, it is another that the pull rod for drawing cone 6 through through hole 10 extends to bearing 1
Side, draws 6 coneheads of cone and pressure cone 7 to be in contact respectively with left power transmission roller 8 and right power transmission roller 9.
Drawing in 7 outside of pressure cone is bored is set with hollow hydraulic cylinder 11, the cylinder rod top of hollow hydraulic cylinder 11 on 6 pull rods
It is in contact with pressure 7 bigger diameter ends of cone, passes through clamp nut 12 and gasket between the cylinder barrel bottom of hollow hydraulic cylinder 11 and drawing 6 pull rods of cone
