[0023] The lower end of the fixed ring is provided with support rods 10 connected with the ring seat 5 and arranged in an annular array;

[0024] The inner part of the upper end of the ring seat 5 is provided with a rolling groove 18, and the lower end of the rotating ring 7 is rotatably installed with a ball 22 rollingly installed in the inner part of the rolling groove 18;

[0025] The telescopic end of the hydraulic rod 6 is provided with a connecting block 21 connected with the toothed plate 20;

[0026] One side of the upper end of the ring seat 5 is provided with a guide rail 19, and the lower end of the toothed plate 20 is provided with a sliding groove slidingly installed with the guide rail 19;

[0027] The mounting ring 8 is internally embedded with sliding sleeves 16 arranged in an annular array, and one end of the clamping rod 11 is slidingly inserted into the sliding sleeves 16;

[0028] The clamping rod 11 is provided at one end with a clamping block 17 with an arc-shaped inner wall and coinciding with the center of the mounting ring 8, and is provided at one end with a positioning seat 13, and the positioning seat 13 is internally rotatably mounted with a positioning bead 14;

[0029] The clamping block 17 is internally provided with a rubber pad, the mounting frame 1 is provided at the upper end with a motor 2, the motor 2 is provided at the upper end with a rotating disc 3, and the rotating disc 3 is provided at the upper end with a conical cylinder 4 located directly below the annular seat 5;

[0030] Based on the implementation steps of Example 1: The annular metal part is inserted into the outer wall of the conical cylinder 4 and supported by the conical cylinder 4, and another annular metal part to be welded is placed on the annular metal part when it is connected. At this time, the hydraulic rod 6 operates, the hydraulic rod 6 drives the gear plate 20 to move, because the gear plate 20 is engaged with the gear ring 23, and the rotating ring 7 is rotatably mounted in the annular seat 5 through the ball 22, which drives the rotating ring 7 to rotate, and the rotating ring 7 drives the arc block 9 to rotate. Because the inner wall thickness of the sliding block gradually increases towards one side, the positioning bead 14 is gradually subjected to extrusion force when passing through the positioning bead 14, and the clamping rod 11 is forced to move the clamping block 17. Because multiple clamping rods 11 cooperate with the arc block 9, the clamping rods 11 are synchronously stressed, and in this process, the spring 15 is stressed to shrink, and the clamping rod 11 synchronously displaces the clamping block 17 to clamp the outer wall of the annular metal part, achieving convenient clamping of the annular metal part. The annular seat 5 is provided with two annular seats 5 for separately clamping two annular metal parts to be welded, and after clamping, the gap between the annular seats 5 corresponds to the joint surface of the annular metal part, which is used as a welding operation space for the welded assembly. During the welding process, the annular metal part is conveniently positioned, and after welding a piece of area, the clamping block 17 ends the clamping of the annular metal part, and the rotating disc 3 is driven to rotate by the motor 2, thereby driving the conical cylinder 4 to rotate. Because the lowermost annular metal part is sleeved on the outer wall of the conical cylinder 4, and the annular metal part has already been welded with part of the structure at this time, the conical cylinder 4 rotates while driving the two annular metal parts to rotate, thereby adjusting the position of the un-welded annular metal part, and achieving convenient adjustment of the position of the annular metal part during the welding process;

[0032] The above specific embodiments are only several preferred embodiments of the present application, and based on the technical solutions of the present application and the related inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
