[0003] When the curved surface and thin wall of a thin-walled flange are precision welded to the flange end, it is necessary to first clamp the curved surface of the thin-walled flange with a clamping device. The currently commonly used clamping device usually adopts a three-point contact clamping method. Although it can firmly clamp the thin-walled flange to be precision-machined, the clamped area of ​​the thin-walled flange will be deformed due to excessive pressure, affecting the welding accuracy.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] A thin-wall clamping device for thin-wall flange welding comprises a sleeve body 1. The sleeve body 1 is a cylindrical structure with two ends open. The inner wall diameter of the sleeve body 1 is adapted to the outer diameter of the cylindrical thin-wall curved surface of the thin-wall flange.

[0023] The inner edges of the bottom of the sleeve body 1 extend horizontally inward to form an annular support portion 2, which is convenient for supporting one end of the cylindrical thin wall to be welded.

[0024] The outer edge of the top of the sleeve body 1 extends horizontally outward to form an annular limiting portion 3, which is convenient for limiting the position of an external manipulator when clamping and prevents the external manipulator from sliding when clamping.

[0025] A notch 4 is provided on the curved side wall of the sleeve body 1, and the notch 4 extends from the top of the sleeve body 1 to the bottom of the sleeve body 1, and the notch 4 passes through the upper and lower surfaces of the annular support part 2, and the notch 4 passes through the upper and lower surfaces of the annular limiting part 3; such an arrangement makes the sleeve body 1 have a certain elasticity.

[0026] In this embodiment, an elastic rubber layer 5 is provided on the inner wall of the sleeve body 1 to further ensure the surface quality of the clamped thin wall when the clamping device clamps the thin wall.

[0027] Furthermore, in this embodiment, Figure 1 and Figure 2 As shown, a slot 6 is provided on the inner wall of the sleeve body 1 around its circumferential direction; an inserting protrusion (not shown in the figure) adapted to the slot 6 is provided on the outer wall of the elastic rubber layer 5, and the elastic rubber layer 5 is inserted into the slot 6 on the inner wall of the sleeve body 1 through the inserting protrusion to achieve a detachable connection, which is convenient for subsequent disassembly and cleaning.

[0028] In this embodiment, if Figure 3 As shown, the top of the sleeve body 1 is provided with an annular slot 7, as shown in FIG. Figure 4 As shown, an elastic thin plate 8 is inserted into the annular slot 7; when the cylindrical thin wall is welded to the flange end, the elastic thin plate 8 effectively covers the outer wall of the cylindrical thin wall to avoid damage to the cylindrical thin wall during welding.

[0029] When the above-mentioned clamping device is in use, the elastic rubber layer 5 is inserted and mounted on the inner wall of the sleeve body 1, and the elastic thin plate 8 is inserted into the annular slot 7, and the cylindrical thin wall to be welded is sleeved on the assembled manipulator. The manipulator is started so that the clamping device firmly clamps the cylindrical thin wall to be welded, and then enters the next step of welding with the flange end.
