precise positioning of the pump technical solution, when the technical solution is used, the first double-shaft motor 416 drives the first wheel rod 415 to rotate, and causes the first wheel rod 415 to be placed above the two support rods 202 and press the elbow downwards, so that the support rod 202 cooperates with the support plate 201 to drive the tension spring 208 to be in a stretching state, and causes the elbow to be placed vertically upwards, when the first double-shaft motor 416 drives the first worm rod 415 to rotate and drive the first worm rod 414 to drive the first connecting block 403 to move upwards to clamp the connecting block 402, and drive the connecting block 402 to move the connecting block 402 to clamp the connecting block 402, and drive the connecting block 402 to move clockwise, until the detection value of the pressure sensor on the opposite surface of the clamping plate 3 reaches the target value, at this time, due to the particularity of the elbow, namely, two ends of the radial position of the elbow are located on the same plane, namely, when the elbow is stably clamped by the two clamping plates 3, and one end of the opposite surface of the clamping plate 3 is perpendicular to the ground, the elbow can be always vertically arranged with the ground after being clamped by the two clamping plates 3, so as to complete the clamping of the elbow, at this time, the driving gear 411 is powered on by the driving motor 413 to drive the driving gear 411 to rotate, and the driving gear 411 drives the driven gear 410 to rotate, and further the driven gear 410 drives the driving sleeve 409 to rotate, because the surface of the first driving column 408 and the inner wall of the driving sleeve 409 are respectively in a regular polygon structure, when the driving sleeve 409 rotates, the first driving column 408 is driven to rotate, and the first driving column 408 drives the clamping plates 3 to rotate through the first connecting column 407, so that the holding plate 3 drives the elbow to rotate around the first connecting column 407, and when the elbow rotates, the elbow drives the supporting rod 202 to move downwards, and further the supporting rod 202 drives the supporting plate 201 to move downwards, wherein the arc surface of the elbow drives the supporting plate 201 to move downwards by a distance following the above formula, i.e. y = sinx, and when the supporting plate 201 moves downwards, the supporting plate 201 drives the sliding contact 203 to move downwards along the surface of the metal rod 204, and the sliding piece 206 moves downwards on the surface of the coil set 205, wherein the sliding contact 203, the metal rod 204, the coil set 205 and the sliding piece 206 can form a sliding rheostat, i.e. by changing the connection mode at the two ends of the coil set 205, the voltage or current value in the line of the sliding rheostat can be in direct proportion to the value of the downward movement distance of the supporting plate 201, therefore, once the voltage or current value has a tendency of being separated from the y = sinx trigonometric function, it is indicated that the elbow and the support plate 201 are at the tangent edge at the moment, the angle sensor records the rotation angle of the elbow under the condition, and the driving motor 413 is controlled to drive the driving gear 411 to rotate in the reverse direction until the clamping plate 3 drives the elbow to move to the position where the voltage or current value is about to be separated from the y = sinx trigonometric function, that is, the elbow and the support plate 201 are at the tangent edge state at the moment, and the welding position of the elbow is aligned with the pipeline to be welded, so that the accurate positioning during the welding of the elbow is realized, the phenomenon that the welding angle of the elbow is not consistent with the actual requirement, the pipeline loading difficulty is caused, and the service life is influenced is avoided, the guide rod 207 is arranged to be matched with the tension spring 208, so that the support plate 201 is always tightly attached to the bottom of the elbow, meanwhile, the positioning groove 209 is matched with the push-pull type electromagnet 210 and the positioning block 211, so that when the elbow is positioned at the tangent edge with the surface of the supporting plate 201, the push-pull type electromagnet 210 drives the positioning block 211 to move towards the inner wall of the positioning groove 209, and the positioning block 211 is tightly attached to the inner wall of the positioning groove 209, thereby limiting the movement of the supporting plate 201, preventing the supporting plate 201 from accidentally moving downwards during welding to cause welding angle deviation, when a pipeline to be welded enters the top of the supporting rod 202 through the guide of the conveying device and the material guide plate 5, the first rotating column 604 is driven to rotate by the second double-shaft motor 625, the second worm wheel lever 624 drives the second worm wheel 623 to rotate, further the second worm wheel 623 drives the transmission column 610 to rotate, and when the transmission column 610 rotates, the transmission column 610 drives the driving bevel gear 609 to rotate, further, the driving bevel gear 609 drives the first bevel gear 607 and the second bevel gear 608 to rotate in opposite directions, since the first bevel gear 607 is rotationally connected to the first rotating column 604 through the bearing, the first bevel gear 607 is used for stabilizing the meshing state between the second bevel gear 608 and the driving bevel gear 609, at this time, the driving bevel gear 609 drives the second bevel gear 608 to rotate, so that the second bevel gear 608 drives the first toothed disc 617 to rotate through the second toothed disc 618, and when the first toothed disc 617 rotates, the first toothed disc 607 drives the second driving column 616 to rotate, since the surface of the second driving column 616 and the inner wall of the driving groove 615 are both regular polygon structures, when the second driving column 616 rotates, the second driving column 616 drives the second rotating arm 603 to rotate towards the top of the pipe to be welded through the driving groove 615, and the second rotating arm 603 drives the first rotating arm 602 and the upper feeding roller 614 to move towards the surface 611 of the pipe to be welded through the first connecting plate 621 and the second connecting plate 613, so that the upper rotating arm 613 and the upper feeding roller 614 are synchronously driven by the second rotating shaft 612 and the second rotating shaft 618, and the second rotating arm 610 can not be matched with the second rotating shaft 618, and the second rotating shaft 614, and the second rotating shaft 618 can not press against the upper rotating shaft 603 and the upper rotating shaft 614, and the second rotating shaft 603, and the second rotating shaft 614, and the second rotating shaft 603 can not be matched with each other rotating shaft, and the second rotating shaft 618. Until the driving bevel gear 609 is engaged to one sixth of the second bevel gear 608 without a tooth groove, idle rotation occurs between the driving bevel gear 609 and the second bevel gear 608, that is, the second bevel gear 608 cannot be driven to rotate any more by the rotation of the driving bevel gear 609, but the rotation of the driving bevel gear 609 drives the feeding roller 614 to rotate by the second connecting column 611 in cooperation with the universal shaft 612 and the transmission shaft 613, because the surfaces of the first rotating arm 602 and the second rotating arm 603 are smoothly arranged, and the surface of the feeding roller 614 is a rubber material member, so that the first rotating arm 602 and the second rotating arm 603 do not obstruct the movement of the pipe to be welded, and the feeding roller 614 drives the pipe to be welded to move towards one end of the elbow to be welded until the elbow is aligned with one end of the pipe to be welded, and then the welding work of the elbow and the pipe to be welded can be performed, and during the first rotating arm 602 and the second rotating arm 603 are attached to the surface of the pipe to be welded, the return spring 620 is in an axial and radial compression state, that is, when the elbow 608 and the second double-shaft motor is engaged with the second bevel gear 610 and the elastic force of the driving bevel gear can be used again, so that the elastic force of the second bevel gear 602 and the return can be used again.
