Two loading slides 81 are supported on the slide rails arranged above the bottom frame of the frame through rollers 22, so the symmetry plane of the loading slides 81 coincides with the longitudinal symmetry plane of the frame, one loading slide 81 is located on the side of the frame column away from the slide, and the other loading slide 81 is located on the side of the slide column away from the frame column. One end of the grabbing rod 821 of the grabbing head 82 is installed at the end of the flip arm 818 of the loading slide 81, and the axis of the grabbing rod 821 coincides with the symmetry plane of the loading slide 81, and the end of the flip arm 818 is installed on the side away from the grabbing rod 821, and the power output shaft of the grabbing drive 822 is coaxial with the grabbing rod 821; the two-way adjustment assembly 824 equipped with a two-way drive 824 is installed at the end of the grabbing rod 821 away from the grabbing drive 822, and two grabbing pins 826 equipped with electromagnets 825 are installed On the side of the two-way adjustment component 824 away from the grabbing rod 821; therefore, the two-way drive 824 can adjust the two grabbing pins 826 to be close to or away from the center of the two-way adjustment component 824 through the left-hand and right-hand screws of the two-way adjustment component 824 to meet the grabbing requirements of the different bolt hole diameters of the flange to be welded; in addition, the grabbing drive 822 can drive the two grabbing pins 826 to rotate around the grabbing drive 822 axis through the two-way adjustment component 824, so as to align with the bolt hole of the flange and insert it into the hole. The flange frame 83 is installed on the loading slide plate 811 of the loading slide 81, and the flange to be welded is placed horizontally in the flange frame 83.When the flipping drive 817 of the loading slide 81 drives the grabbing head 82 to rotate through the flipping arm 818 until the axis of the grabbing rod 821 is perpendicular to the surface of the loading slide plate 811, that is, it is in a grabbing state, the upward sliding drive 815 of the loading slide 81 drives the flipping drive 817, the flipping arm 818 and the entire grabbing head 82 to move down through the loading slider 816 until the ends of the two grabbing pins 826 contact the end faces of the flange, the grabbing drive 822 of the grabbing head 82 drives the two grabbing pins 826 to rotate around the axis of the grabbing drive 822 through the two-way adjustment assembly 824, and when the ends of the two grabbing pins 826 are aligned with the bolt holes of the flange, the two grabbing pins 826 are respectively inserted into the bolt holes of the flange; at the same time, the electromagnet 825 is energized to adsorb and grab the flange to be welded and send it to the clamping station.
[0011] Its working principle is: turn on the power, start the double adjustment drive of the grabbing head of the flange feeding device of the multi-gun steel pipe flange automatic welding machine according to the diameter of the flange to be welded, and adjust the two grabbing pins to approach or move away from the center of the two-way adjustment component at the same time through the left-hand and right-hand screws of the two-way adjustment component to adapt to the grabbing requirements of the circle diameters of the different bolt holes of the flange.
[0012] Start the control program of the multi-gun steel pipe flange automatic welding machine, the feeding platform drive of the feeding slide of the flange feeding device starts, and drives the flange feeding device to retreat to the frame and the welding slide away from the column; the flip drive of the feeding slide of the flange feeding device starts, and drives the flip arm and its grab head to rotate until the axis of the grab head is in a plumb state; the flange rack of the flange feeding device is filled with flanges to be welded. The upward sliding drive of the flange feeding device drives the feeding slider mounted on the feeding linear rail of the feeding slide and the flip drive and flip arm slidably mounted on the feeding slider to move downward, thereby driving the grab head to move downward together; at the same time, the grab drive of the grab head drives the two-way adjustment component, the electromagnet and the grab pin to rotate at a low speed; when the grab pin gradually approaches the flange to be welded in the flange frame and aligns with the bolt hole of the flange to be welded, the grab pin is inserted into the bolt hole of the flange to be welded, the grab drive rotates in the opposite direction, and stops at the set position; at the same time, the electromagnet is energized, so that the flange to be welded is adsorbed on the two-way adjustment component. The flipping drive of the grabbing head drives the grabbing head and the flange to be welded to rotate toward the flange positioning device of the flange clamping device through the flipping arm, and gradually rotates until the axis of the grabbing head tends to be horizontal; the upward sliding drive of the loading slide of the flange loading device is started again, and drives the grabbing head and the flange to be welded to move downward through the loading slider; the loading table drive of the loading slide of the flange loading device rotates in the opposite direction, and drives the flange loading device and the grabbed flange to be welded to be pushed toward the flange positioning device; when pushed to the top of the V-groove wheels of the positioning active component and the positioning driven component, the upward sliding drive is started again, and drives the loading slider as well as the grabbing head and the flange to be welded to move downward, and directly places the flange to be welded on the two V-groove wheels of the positioning active component and the positioning driven component.
[0013] After welding is completed, the loading table drive of the loading slide of the flange loading device starts in reverse, and drives the flange loading device to retreat to the frame and the welding slide away from the column; the flipping drive of the loading slide of the flange loading device starts in reverse, and drives the flipping arm and its grabbing head to rotate again until the axis of the grabbing head is in a plumb state, waiting to grab the flange to be welded again.
