The fitting 45 is arranged on the sleeve 44 and moves synchronously with the sleeve 44, the outer wall of the fitting 45 abutting against the inner wall of the window 101. The fitting piece 45 and the step 33 play a similar role, and the workpiece 1 cannot be freely moved through the limitation of the fitting piece 45, so that the positioning is realized.

The working principle is as follows:

during the overlaying operation, the output end of the welding gun is basically fixed.

When the surfacing operation is performed on the welding surface of the workpiece 1 far from the ground, the driving mechanism 8 drives the platform 31 and the workpiece 1 on the platform 31 to axially rotate through the main shaft 32, so that the welding gun continuously operates on the whole annular welding surface.

When surfacing operation is carried out on a welding surface of the workpiece 1 facing the ground, the swing arm 6 drives the support 7 to rotate circumferentially, so that the first movable part 2 and the second movable part 3 are turned over wholly, and the end surface of the platform 31 faces the ground; at this time, the welding surface of the workpiece 1 originally facing the ground is also turned over to face a direction away from the ground, so that the welding gun can continuously perform the operation on the welding surface.

When the plurality of workpieces 1 are operated, the welding surfaces of the plurality of workpieces 1 in the same direction are sequentially operated, and then the workpieces 1 are turned over, and then the other welding surfaces of the plurality of workpieces 1 are sequentially operated in the same manner.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
