A rotating rod 102 is provided between the two bearing seats 101 of each group of bearing seats 101, and the rotating rod 102 can rotate between the two bearing seats 101. Friction rollers 103 are provided on the two rotating rods 102, and pipes of different diameters can be placed between the two friction rollers 103. A driving motor 103 is also fixed to the base plate 100 by bolts. 4. The output shaft of the driving motor 104 is connected to the end of one of the rotating rods 102, and the driving motor 104 can drive one of the rotating rods 102 to rotate. An L-shaped support frame 105 is also provided on the bottom plate 100. A linear slide 106 is longitudinally provided at the bottom of the support frame 105. The linear slide 106 includes a movable block 107 that can slide back and forth. A lifting rod 108 is vertically provided at the bottom of the movable block 107. The lifting rod 108 can be set as an electric push rod or a hydraulic push rod, etc. A welding gun 109 is provided at the bottom of the lifting rod 108, and the lifting rod 108 can drive the welding gun 109 to move up and down;

[0026] Two pipes to be welded are placed between two friction rollers 103, and then the driving motor 104 is controlled to work. When the driving motor 104 works, one of the rotating rods 102 can drive the friction roller 103 to rotate. When one of the friction rollers 103 rotates, the pipe can be driven to rotate between the two friction rollers 103 under the action of friction force. At the same time, the lifting rod 108 is controlled to move downward with the welding gun 109, and the welding gun 109 can perform circumferential seam welding on the rotating pipe. The lifting rod 108 is set on the support frame 105 through the linear slide 106, that is, the position of the welding gun 109 can be adjusted through the linear slide 106, so that the welding gun 109 can weld the pipe at different positions, and then two pipes of different lengths can be welded.

[0027] Positioning wheel 204 Figure 3 As shown,

[0028] Two slide grooves 200 are symmetrically arranged on the upper surface of the bottom plate 100. The slide groove 200 is located at the midline position between the two bearing seats 101. A threaded rod 201 is arranged in the slide groove 200 through a bearing. The threaded rod 201 can rotate in the slide groove 200. A slider 202 is arranged in the slide groove 200 corresponding to the threaded rod 201. A threaded hole is arranged on the slider 202 corresponding to the threaded rod 201. The threaded rod 201 passes through the threaded hole and is connected to the slider 202. The rotation of the threaded rod 201 can drive the slider 202 to move left and right in the slide groove 200. A telescopic component 300 is vertically arranged on the upper surface of the slider 202. A positioning rod 203 is horizontally arranged at the end of the telescopic component 300. The telescopic component 300 can drive the positioning rod 203 to move up and down. A positioning wheel 204 is arranged on the positioning rod 203 through a bearing. The positioning wheel 204 can rotate on the positioning rod 203.

[0029] After the two pipes are placed at the specified positions, the threaded rod 201 is controlled to rotate in the slide groove 200. The rotation of the threaded rod 201 can drive the slider 202 to move in the slide groove 200. The movement of the slider 202 toward the end of the pipe can drive the telescopic component 300 and the positioning rod 203 to rotate. After the positioning wheel 204 moves to the side of the pipe, the telescopic component 300 can pull the outer wall of the positioning wheel 204 to contact the inner wall of the pipe. When the pipe rotates, the positioning wheel 204 can contact the inner wall of the pipe to limit the pipe, thereby preventing the pipe from jumping during rotation.

[0030] A snap ring 205 is provided on the side of the positioning wheel 204; the positioning ring is arranged on the side of the positioning wheel 204 away from the pipe, that is, during the rotation of the positioning wheel 204, the snap ring 205 can contact the side of the pipe to limit the pipe, and the chicken will not move between the two friction rollers 103 during the rotation of the pipe.

[0031] The outer surfaces of the friction roller 103 and the positioning wheel 204 are both provided with a rubber layer; the rubber layer can increase the friction between the friction roller 103 and the positioning wheel 204 and the pipeline, thereby preventing the pipeline from slipping between the two friction rollers 103 when the friction roller 103 rotates.

[0032] Telescopic assembly 300 Figure 4 As shown,

[0033] The telescopic assembly 300 includes a fixed rod 301 arranged on the upper surface of the vertical slider 202, and a movable groove 302 is vertically provided on the upper surface of the fixed rod 301. A movable rod 303 is slidably provided in the movable groove 302. The movable rod 303 can slide up and down in the movable groove 302. The positioning rod 203 is arranged horizontally on the movable rod 303. The movable rod 303 can drive the positioning rod 203 to move up and down. A spring 304 is also provided in the movable groove 302, one end of the spring 304 is connected to the end of the movable groove 302, and the other end of the spring 304 is connected to the end of the movable rod 303; the spring 304 can always push the movable rod 303 to the end away from the base plate 100.

[0034] The movable rod 303 and the movable groove 302 are both T-shaped structures; that is, the movable rod 303 will not fall off from the movable groove 302 during the process of sliding up and down in the movable groove 302 .

[0035] The cross sections of the movable rod 303 and the movable groove 302 are both polygonal structures; that is, the movable rod 303 will not rotate in the movable groove 302 during the up and down sliding process, so the position of the positioning wheel 204 will not rotate, and the positioning wheel 204 can normally limit the pipeline.

[0036] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
