Because the outer diameters of the oil pipes 101 are different, when aiming at the oil pipes 101 with different outer diameters, the distance between the welding head 12 and the oil pipe 101 needs to be adjusted in advance so as to ensure the optimal position for subsequent welding, and the specific operation is as follows: in the initial state, the right side of the L-shaped rack 1803 is clamped into the clamping groove 14061, the L-shaped rack 1803 is meshed with the third gear 1804, when the oil pipe 101 is fixed, the fixing block 1406 moves rightwards, the L-shaped rack 1803 is driven by the clamping groove 14061 to move rightwards, the third gear 1804 drives the third gear 1804 to rotate the first threaded rod 1505, the first threaded rod 1505 drives the U-shaped rack 1504 to move forwards, the U-shaped rack 1504 drives the two lantern rings 1503 and the fixing plate 1601 to move forwards, the two lantern rings 1503 drive the two limit frames 1502 to move forwards, the two limit frames 1502 drive the two fixing columns 1501 to move forwards, the welding head 12 drives the slide rail 11 to move forwards, when the two limit frames 1502 move forwards, the two limit frames 1603 drive the two rectangular frames 1603 to move forwards, the threaded rod 1605 drives the second threaded rod 1602 to move forwards through the clamping blocks 1604, the fixing plate and the second threaded rod 1602 to move forwards synchronously, and the second annular frame 1504 drives the two limit frames 1502 to move forwards, and the distance between the two limit frames is kept to be smaller than the optimal distance between the welding head 12 and the welding head 101 is guaranteed.
Because the section of the oil pipe 101 is elliptical, the moving track of the welding head 12 should be similar to the ellipse, so as to ensure the optimal welding distance, and the specific operation is as follows: in the initial state, the left and right sides of the folded rack 1901 are respectively meshed with the fifth gear 1903 and the fourth gear 1902, during the process of rotating the oil pipe 101, the fixed sleeve 1306 drives the Y-shaped frame 1304 at the rear side to rotate anticlockwise, the Y-shaped frame 1304 drives the fourth gear 1902 to rotate, the fourth gear 1902 drives the fifth gear 1903 to rotate through the folded rack 1901, the fifth gear 1903 drives the second threaded rod 1602 to rotate, the second threaded rod 1602 moves backwards under the limit of the threads on the fixed plate 1601, the second threaded rod 1602 drives the rotating rod 1605 to move backwards, the rotating rod 1605 drives the two clamping blocks 1604 to move backwards, the two clamping blocks 1604 respectively drive the rectangular frame 1603 and the limiting frame 1502 to rotate with the fixed column 1501 as the rotation center, when the oil pipe 101 is not rotated any more, the lower side of the limit frame 1502 is not further away from the oil pipe 101, the deflection angle of the limit frame 1502 and the rotation angle of the oil pipe 101 are in a linear relationship, the rotation angle of the oil pipe 101 is equal to the inclination angle of the tangential plane of the oil pipe 101 (the included angle of the tangential plane and the cross section of the oil pipe 101), and the larger the inclination angle of the tangential plane (ellipse) of the oil pipe 101 is, the longer the major axis of the ellipse is, so when the welding head 12 rotates to the lower side of the joint of the two oil pipes 101, the rotation radius of the welding head 12 should be increased to ensure the distance between the welding head 12 and the joint of the two oil pipes 101.
After the sections of the two oil pipes 101 are parallel, the control terminal starts the two telescopic brackets 3, so that the central line point of the rotating ring 7 coincides with the connecting line of the central points of the sections of the two oil pipes 101, then, the control terminal 2 closes the two telescopic brackets 3 and starts the third electric push rod 1801, the telescopic end of the third electric push rod 1801 drives the limiting block 1802 to move backwards, the limiting block 1802 drives the L-shaped rack 1803 and the folded rack 1901 to move backwards, the right side of the L-shaped rack 1803 is moved out of the clamping groove 14061, the left side of the L-shaped rack 1803 moves backwards and loses engagement with the third gear 1804, and at the same time, the dog bone 1901 moves backward and loses the engagement with the fourth gear 1902 and the fifth gear 1903 respectively, then, the control terminal 2 stops the third electric push rod 1801 and starts the two first electric push rods 1301, the telescopic ends of the two first electric push rods 1301 drive the adjacent push blocks 1302 to be close to each other respectively, the push blocks 1302 drive the parts thereon and the oil pipes 101 to be close to each other, when the tangential surfaces of the two oil pipes 101 are in contact with each other and are located on the same plane with the welding head 12, the control terminal 2 stops the two first electric push rods 1301, the two oil pipes 101 are not close to each other any more, and then the joint of the two oil pipes 101 is welded, and the following specific operations are performed: the control terminal 2 starts the servo motor 5, the output shaft of the servo motor 5 drives the first gear 6 to rotate, the first gear 6 drives the rotating ring 7 to rotate through the first gear ring 8, the rotating ring 7 drives the L-shaped rod 9 and the speed reducer 1702 to rotate clockwise (right view direction of fig. 1), the L-shaped rod 9 drives the parts thereon and the welding head 12 to rotate clockwise, simultaneously, the control terminal 2 starts the welding head 12 to weld the joint of the two oil pipes 101, because the initial welding position of the welding head 12 is positioned at the short axis of the joint (ellipse) of the two oil pipes 101, during the clockwise rotation of the welding head 12, the welding position of the welding head 12 moves from the short axis of the joint (ellipse) of the two oil pipes 101 to the long axis, therefore, the welding head 12 needs to be far away from the oil pipes 101, during the clockwise rotation of the speed reducer 1702, the speed reducer 1702 rotates the second gear 1703 clockwise, and the second gear 1703 is meshed with the second gear ring 1701, so that the second gear 1703 rotates clockwise, the second gear 1703 rotates the turntable 1704 clockwise through the speed reducer 1702, the turntable 1704 rotates the eccentric shaft 1705 clockwise, the eccentric shaft 1705 moves the L-shaped plate 1506 upward, the L-shaped plate 1506 moves the third gear 1804 and the fifth gear 1903 upward, the third gear 1804 and the fifth gear 1903 move the U-shaped frame 1504 and the fixing plate 1601 upward through the first threaded rod 1505 and the second threaded rod 1602, the U-shaped frame 1504 moves the two limiting frames 1502 upward through the two collars 1503, the limiting frames 1502 keep the inclined state upward, the inner rings of the two limiting frames 1502 move upward to press the two fixing columns 1501 away from the oil pipe 101, the two fixing columns 1501 drive the welding head 12 away from the oil pipe 101, therefore, when the welding head 12 rotates from the rear side to the lower side, the welding head 12 is gradually far away from the oil pipes 101, so that the distance between the welding head 12 and the two oil pipes 101 is maintained in an optimal range, and the welding quality is ensured.
When the welding head 12 rotates to the lower side, the eccentric shaft 1705 rotates to the upper side of the turntable 1704, at this time, the limiting frame 1502 does not move upwards any more, as the welding head 12 continues to weld, the welding head 12 rotates from the lower side to the front side, the eccentric shaft 1705 rotates from the upper side of the turntable 1704 to the lower side, the limiting frame 1502 gradually moves downwards to press the fixing column 1501 so that the welding head 12 approaches the oil pipe 101, then the above steps are continuously repeated to weld the upper side of the joint of the two oil pipes 101, the speed reducer 1702 makes the welding head 12 rotate for one turn and the turntable 1704 rotate for two turns, after the welding head 12 rotates for one turn, the welding head 12 rotates to the initial position, and the welding process is completed.
