The technical scheme that its technical problem that solves the utility model adopts is: it comprises pressing plate, pipe box, pull bar, supporter, cone, piece, copper cushion block, sunk screw, garter spring, adjusting nut, packing ring, locking nut expand;
The front end of pull bar has external screw thread, and there is a limited step its rear end, and the rear end of pull bar is set in the centre bore of cone and fixes through welding;
The front end of pipe box has external screw thread, and there is a seam its rear end, and the rear end seam of pipe box is plugged in the centre bore bead of supporter and through being welded to connect;
The adjusting nut spinning is on the external screw thread of pipe box front end, and pressing plate is inserted in the front end of pipe box, and by being loaded on the outside of adjusting nut, there is a circle annular stopper outer of pressing plate, and the internal diameter of the external diameter of annular stopper and thin-walled hollow cylindrical shell to be welded equates;
The pull bar of the cone that is welded is threaded onto the pipe box from the rear end, and packing ring is inserted in the front end of pull bar and by being loaded on the outside of pressing plate, the locking nut spinning is on the external screw thread of pull bar front end;
Bloated piece is to be mutually 120 ° five equilibrium three-clove style structure; Two garter springs are loaded on respectively on the piece external cylindrical surface that expands in two cannelures radially; Garter spring makes the bloated piece of three-clove style form an integral body, and the inwall of the piece that expands has certain taper, and the tapering of its tapering and outer surface of cone is identical;
Copper cushion block is fixed in the external cylindrical surface of the piece that expands through sunk screw, and the surface of copper cushion block has a radial ringed groove.
The utility model is compared the beneficial effect that is produced with background technology:
1, owing to adopting pressing plate that workpiece is positioned,, can effectively solve the orientation problem that attaches together when being with seal end thin wall cylindrical shell and the butt welding of thin-walled hollow cylindrical shell, realize accurate coaxial positioning between the two through the bloated piece of the bloated three-clove style in cone top.
2, simple in structure, easy installation and removal, manipulate reliable.
