A mounting seat 9 is sleeved on the outer side of the screw rod 8, and a placement plate 10 is fixedly connected to the top of the mounting seat 9.

[0033] Among them, a slide groove 11 is opened inside the placement plate 10, a slide rod 12 is fixedly connected inside the slide groove 11, a slider 13 is sleeved on the outside of the slider 12, a mounting tube 14 is fixedly connected to the top of the slider 13, a thread is set on the outside of the mounting tube 14, and a threaded sleeve 16 is installed on the outside of the mounting tube 14.

[0034] By setting the mounting seat 9, the placement plate 10, the slide groove 11, the slide bar 12, the slider 13, the mounting tube 14, the tightening bolt 15, the threaded sleeve 16 and the fixed suction cup 17, when it is necessary to weld the metal parts, the metal parts are placed on the top of the mounting seat 9, and the position of the fixed suction cup 17 is adjusted according to the shape of the metal parts. The fixed suction cup 17 is unscrewed so that the threaded sleeve 16 and the threads on the mounting tube 14 are rotated and disengaged, and the tightening bolt 15 is loosened to release the pressure of the tightening bolt 15 on the slide bar 12, and then the mounting tube 14 is slid, and the mounting tube 14 drives the slider 13 to slide on the slide bar 12, and then adjusted to a suitable position.

[0035] Next, tighten the tightening bolt 15 to limit the slider 13, and then screw the threaded sleeve 16 onto the outside of the mounting tube 14 and install it, so that the multiple fixed suction cups 17 can be adjusted to different positions, which is convenient for adjustment according to different shapes of metal parts. The metal parts are then adsorbed and positioned by the multiple fixed suction cups 17, which improves the convenience and stability of positioning irregular-shaped metal parts, reduces the displacement of irregular metal parts during welding, improves welding accuracy, and solves the problem of poor clamping effect when positioning irregular-shaped metal parts, which may cause metal parts to shift during welding and affect the accuracy of subsequent welding.

[0036] The mounting seat 9 is threadedly connected to the screw rod 8 , there are no less than three slide grooves 11 , the slider 13 is slidably connected to the slide rod 12 , the threaded sleeve 16 is adapted to the thread, and a tightening bolt 15 is installed inside the mounting tube 14 .

[0037] The tightening bolt 15 is threadedly connected to the mounting tube 14 , and the tightening bolt 15 passes through the slider 13 and abuts against the top of the slide rod 12 . Two positioning plates 18 are symmetrically arranged up and down.

[0038] Among them, the top of the threaded sleeve 16 is fixedly connected with a fixed suction cup 17, one side of the placement plate 10 is fixedly connected with a positioning plate 18, and the other side of the placement plate 10 is internally provided with a positioning groove 19, the number of the positioning grooves 19 matches the positioning plate 18, and the positioning plate 18 is snap-connected with the positioning groove 19.

When the position of the fixed metal part needs to be adjusted, the servo motor 7 is started, and the servo motor 7 drives the screw 8 to rotate. The limit block 22 slides on the limit rod 21 to limit the mounting seat 9, so that the mounting seat 9 moves left and right, thereby facilitating the adjustment of the welding position. At the same time, when the metal part to be welded is large, the positioning groove 19 of another placement plate 10 can be stuck to the positioning plate 18 on one side of the existing placement plate 10, thereby realizing the area extension of the placement plate 10, which is convenient for positioning metal parts with larger area sizes.

[0041] Working principle:

[0042] Before using this metal structure welding device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6 As shown, when it is necessary to weld metal parts, place the metal parts on the top of the mounting seat 9, adjust the position of the fixed suction cup 17 according to the shape of the metal parts, unscrew the fixed suction cup 17, so that the threaded sleeve 16 and the thread on the mounting tube 14 are rotated and disengaged, loosen the tightening bolt 15, release the pressure of the tightening bolt 15 on the slide rod 12, and then slide the mounting tube 14. The mounting tube 14 drives the slider 13 to slide on the slide rod 12, and then adjusts it to a suitable position, then tightens the tightening bolt 15 to limit the slider 13, and then screws the threaded sleeve 16 on the outside of the mounting tube 14 and installs it, so that multiple fixed suction cups 17 can be adjusted to different positions, which is convenient for adjustment according to different shapes of metal parts, and then the metal parts are adsorbed and positioned by multiple fixed suction cups 17.

[0043] During welding, the exhaust device draws air through the exhaust pipe 6, thereby reducing the impact of smoke during welding and facilitating the subsequent welding process. When it is necessary to adjust the position of the fixed metal parts, the servo motor 7 is started, and the servo motor 7 drives the screw rod 8 to rotate. The limit block 22 slides on the limit rod 21 to limit the mounting seat 9, so that the mounting seat 9 moves left and right, thereby facilitating the adjustment of the welding position.

[0044] When the metal parts to be welded are relatively large, the positioning groove 19 of another placement plate 10 can be snapped onto the positioning plate 18 on one side of the existing placement plate 10, thereby extending the area of ​​the placement plate 10 and facilitating the positioning of metal parts with larger areas.
