DETAILED DESCRIPTION

[0016] like Figures 1 to 6 As shown, the present invention provides a titanium alloy pipe welding wire feeding device that is convenient for the rapid positioning of the welding wire, comprising: a support platform 1, two clamping rings 3 for clamping the pipe 2 are fixedly provided on the support platform 1 and are symmetrical about the central axis of the support platform 1, and the two clamping rings 3 are rotatably connected on the side close to each other with an adjusting ring 4, and the adjusting ring 4 is provided with a slide groove 401 on the side away from the clamping ring 3, and a slider 402 that can slide along the radial limit of the adjusting ring 4 is slidably provided in the slide groove 401, and a splint 5 fixedly connected to the two oppositely arranged sliders 402 is provided between the two adjusting rings 4, and the splint 5 is used to clamp the welding wire conduit 6 and the welding gun (not shown in the figure), and an inclined strip hole 403 is provided on the slider 402, and a connecting rod 404 is slidably connected in the strip hole 403, and a connecting rod 404 is slidably provided in the slide groove 401. The connecting plate 405 can slide along the axial limit of the adjusting ring, and the connecting plate 405 is fixedly connected to the connecting rod 404. Sliding the connecting plate 405 can make the connecting rod 404 slide along the strip hole 403 to make the slider 402 slide radially along the adjusting ring 4. The connecting plate 405 is rotatably connected to the threaded rod 406 near the clamping ring 3 side, and the threaded rod 406 is threadedly connected to the adjusting ring 4. The clamping ring 3 is provided with an annular groove 301 near the adjusting ring 4 side, and the inner wall of the annular groove 301 is fixedly provided with an arc-shaped tooth 302. The adjusting ring 4 is rotatably connected to the gear 407 that meshes with the arc-shaped tooth 302 near the clamping ring 3 side, and a keyway 408 is provided in the gear 407. A sliding rod 409 is slidably connected in the keyway 408. The end of the sliding rod 409 extending out of the keyway 408 is coaxially fixedly connected to the threaded rod 406.

[0017] In this solution, the method for feeding wire by the wire feeding device includes the following steps: S1: Two titanium alloy tubes 2 are clamped and fixed by two clamping rings 3 so that the welding position between the two tubes 2 and the center plane of the clamping plate 5 are in the same plane; S2: Fix the welding wire conduit 6 on the clamping plate 5. During the welding process, the solder is fed into the groove between the two pipes 2 through the welding wire conduit 6. During the welding process, the welding wire conduit 6 is made to move in a circular motion with the axis of the pipe 2 as the center by rotating the adjusting ring 4. During the rotation of the adjusting ring 4, the adjusting ring 4 drives the gear 407 to rotate synchronously. When the gear 407 rotates to the arc-shaped tooth 302, the gear 407 is engaged with the arc-shaped tooth 302, which can When the arc-shaped tooth 302 rotates, the rotation of the gear 407 will drive the threaded rod 406 to rotate through the slide rod 409, so that the threaded rod 406 moves axially along the gear 407, thereby driving the connecting plate 405 and the connecting rod 404 to slide, and the connecting rod 404 slides along the inclined strip hole 403 to drive the slider 402 to slide radially along the adjustment ring 4, thereby driving the splint 5 to move radially, so that the distance between the discharge end of the welding wire conduit 6 and the welding position between the two pipes 2 is increased to adapt to layered gradient welding.

[0018] Among them, the setting position of the welding gun and the feeding method of the welding wire conduit 6 are conventional technical means in this field, and how to drive the adjustment ring 4 to rotate through the driving mechanism is also a conventional technical means in this field. I will not go into details here. This application only makes improvements on how to quickly adjust the position of the welding wire conduit 6 during the welding process.

[0019] This solution can automatically adjust the positions of the welding wire guide tube 6 and the welding gun when performing the second layer welding after the first layer welding is performed on the welding position by rotating the adjusting ring 4, so as to ensure fast and uniform material discharge during gradient welding, reduce errors caused by manual welding, and drive the welding wire guide tube 6 and the welding gun to rotate by adjusting the ring 4 to avoid the inconvenience caused by the need to tilt the head when welding the bottom of the pipe 2 during manual welding.

[0020] In one embodiment of the present invention, a connecting rod 410 is fixedly connected between the two sliders 402, the splint 5 is rotatably connected to the connecting rod 410, a support plate 7 is fixedly connected between the two adjustment rings 4, the support plate 7 is U-shaped, a rotating shaft 701 is rotatably connected inside the support plate 7, a driving ring 702 is fixedly sleeved on the rotating shaft 701, an arc-shaped groove 703 connected end to end is provided on the outer wall of the driving ring 702, and a protrusion 704 is fixedly provided on the splint 5 and is slidably connected to the arc-shaped groove 703.

[0021] In this embodiment, during welding, rotating shaft 701 rotates drive ring 702, thereby causing protrusion 704 to slide along arcuate groove 703. Since clamping plate 5 is rotatably connected to connecting rod 410, the sliding of protrusion 704 along arcuate groove 703 causes clamping plate 5 to swing, thereby performing swing welding. The rotation of shaft 701 is driven by a drive motor (not shown).

[0022] In one embodiment of the present invention, an insert block 411 is fixedly provided at the middle of the connecting rod 410 , a strip groove 501 is provided on the clamping plate 5 , and the insert block 411 is slidably connected in the strip groove 501 .

[0023] In this solution, during the welding process, when the adjusting ring 4 rotates, when the gear 407 rotates through the arc-shaped tooth 302, it drives the slider 402 to slide in a direction away from the axis of the adjusting ring 4, thereby driving the connecting rod 401 and the slider 402 to move synchronously, thereby driving the plug 411 to slide along the strip groove 501 to shorten the distance between the plug 411 and the protrusion 704, thereby changing the rotation point of the splint 5, so that the rotation amplitude of the discharge port end of the welding wire conduit 6 is increased to adapt to the groove gap between the two pipes 2.

[0024] In one embodiment of the present invention, an adjustment groove 412 is provided on the side of the slider 402 away from the clamping ring 3, and an adjustment block 413 that can slide radially along the adjustment ring 4 is slidably connected in the adjustment groove 412. The connecting rod 410 is fixedly connected to the adjustment block 413, and an adjustment rod 414 is rotatably connected to the adjustment block 413. The adjustment rod 414 is threadedly connected to the slider 412. Rotating the adjustment rod 414 can make the adjustment block 413 slide radially along the adjustment ring 4.

[0025] In this solution, before welding, the operator can rotate the adjustment rod 414 according to the groove gap to adjust the initial position of the adjustment block 413 to adapt to the welding of pipes with different groove gaps.

[0026] In one embodiment of the present invention, a first strip-shaped notch 705 for avoiding the connecting rod 410 is provided on the vertical side wall of the support plate 7, and a second strip-shaped notch 706 for avoiding the welding wire conduit 6 is provided on the horizontal side wall of the support plate 7.

[0027] In this solution, the strip-shaped notch is provided to ensure the sliding of the connecting rod 410 and the swing of the welding wire conduit 6, and to ensure the compactness and stability of the support plate 7 structure.

[0028] In one embodiment of the present invention, a gap is provided between the inner wall of the clamping ring 3 and the outer wall of the pipe 2. The clamping ring 3 is circumferentially provided with a plurality of clamping blocks 303 centered on the axis of the clamping ring 3. One end of the clamping block 303 is rotatably connected to an operating rod 304. The operating rod 304 is threadedly connected to the clamping ring 3. Rotating the operating rod 304 can make the clamping block 303 approach or move away from the pipe 2.

[0029] In this solution, after the pipe 2 is inserted into the clamping ring 3, the clamping block 303 can be moved close to the pipe 2 by rotating the operating rod 304 to clamp the pipe 2, so as to adapt to the clamping of pipes 2 with different diameters.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
