[0024] First, insert the steel pipe into the interior of the inclined elastic block 7, and then rotate the knob 11 so that the knob 11 drives the threaded ring 10 to rotate inside the screw groove 9, and the triangular clamping ring 12 moves downward to squeeze the inclined elastic block 7, so that the inclined elastic block 7 shrinks inward to fix the steel pipe, and then insert the steel pipe to the outside of the fixed cylinder 19, so that the arc-shaped elastic block 21 is squeezed and shrinks to the inside of the movable groove 20, thereby fixing the steel pipe, and the rectangular plate 16 moves inward to make the steel pipe contact, and the fixed cylinder 19 is driven to rotate by the servo motor 2 17 to rotate between the steel pipes, and the steel pipe drives the disc 4 to rotate inside the L-shaped plate 3.

[0025] By inserting the steel pipe into the interior of the inclined elastic block 7, the inclined elastic block 7 is contracted inward to fix the steel pipe, and then the steel pipe is inserted into the outside of the fixed cylinder 19, so that the arc-shaped elastic block 21 is squeezed and contracted to the inside of the movable groove 20, thereby fixing the steel pipe. Compared with the traditional welding device for steel pipe processing, this continuous welding device for steel pipe processing rotates the two steel pipes relative to each other so that they rotate synchronously, which facilitates welding between the steel pipes.

[0038] The insertion shaft 29 drives the card block 30 to move upward and out of the inside of the card slot 27, thereby squeezing the auxiliary spring 28, causing the auxiliary spring 28 to deform, and then the platform 31 is rotated to rotate the card block 30 to the bottom of the slot 26. At this time, the auxiliary spring 28 releases its elastic potential energy to push the card block 30 out of the inside of the slot 26.

[0039] The working principle and use process of this utility model:

[0040] First, insert the steel pipe into the interior of the inclined elastic block 7, and then rotate the knob 11 so that the knob 11 drives the threaded ring 10 to rotate inside the screw groove 9, and the triangular clamping ring 12 moves downward to squeeze the inclined elastic block 7, so that the inclined elastic block 7 shrinks inward to fix the steel pipe, and then insert the steel pipe to the outside of the fixed cylinder 19, so that the arc-shaped elastic block 21 is squeezed and shrinks to the inside of the movable groove 20, thereby fixing the steel pipe, and the rectangular plate 16 moves inward to make the steel pipe contact, and the fixed cylinder 19 is driven to rotate by the servo motor 2 17 to rotate between the steel pipes, and the steel pipe drives the disc 4 to rotate inside the L-shaped plate 3.

[0041] When the welding head 32 needs to be disassembled, just press the table 31 upwards so that the insertion shaft 29 drives the block 30 to move upward and out of the inside of the slot 27, thereby squeezing the auxiliary spring 28 and deforming the auxiliary spring 28. Then rotate the table 31 and rotate the block 30 to the bottom of the slot 26. At this time, the auxiliary spring 28 releases its elastic potential energy to push the block 30 out of the inside of the slot 26, thereby disassembling the welding head 32.
