DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 5 As shown, this embodiment provides a fully automatic two-way welding device for round tube U-shaped parts, including:

[0032] A frame 1, on which a number of cut steel pipes 2 are arranged obliquely;

[0033] The conveying mechanism includes a feeding assembly and a discharging assembly arranged on the frame 1 along the production process. The feeding assembly is used to feed the steel pipe 2, and the discharging assembly is used to send out the welded parts;

[0034] The feeding mechanism includes a first feeding assembly and a second feeding assembly provided on the frame 1, wherein the first feeding assembly is used to feed the steel pipe 2 into the feeding assembly, and the second feeding assembly is used to pick up the steel pipe 2 from the U-shaped member 3 and position it on the steel pipe 2;

[0035] The welding mechanism is arranged on the frame 1 and is located between the feeding assembly and the discharging assembly; the welding mechanism includes a positioning assembly and a welding assembly arranged on the frame 1, the positioning assembly is used to position the fed steel pipe 2, and the welding assembly is used to weld the U-shaped part 3 to the steel pipe 2.

[0036] The utility model discloses a fully automatic two-protection welding device for round tube U-shaped parts, which is mainly used for automatically welding a U-shaped part 3 to a steel pipe 2. During operation, the cut steel pipe 2 is placed on a frame 1, and the steel pipe 2 is automatically fed into a feeding assembly by a first feeding assembly, and then sent to a welding mechanism by the feeding assembly. The steel pipe 2 is positioned by a positioning assembly, and then the automatically fed U-shaped part 3 is picked up by a second feeding assembly and positioned on the steel pipe 2 fixed by the positioning assembly, and the U-shaped part 3 is welded to the steel pipe 2 by a welding assembly. The positioning assembly releases the welded steel pipe 2, allowing the steel pipe 2 to continue moving forward until the U-shaped part 3 is welded on the surface of the steel pipe 2 according to the design requirements. After welding is completed, the steel pipe 2 enters the discharging assembly and is transferred to the next process by the discharging assembly to complete the welding. The utility model has a compact structure and a high degree of intelligence. It can automatically complete the welding of the U-shaped part 3 with less human intervention and can continuously and efficiently complete the welding quality, thereby improving welding efficiency and welding quality, reducing labor costs, and improving worker protection.

[0037] Furthermore, the frame 1 of this embodiment adopts a frame structure, which can reduce material consumption, facilitate the falling of impurities during the production process, and reduce accumulation.

[0038] A further optimized solution is that the feeding assembly includes a plurality of first support wheels 4 adapted to the steel pipes 2. The steel pipes 2 fall onto the plurality of first support wheels 4. A feeding module slidably mounted on the frame 1 pushes the steel pipes 2 into the positioning assembly. The plurality of first support wheels 4 rotate on the frame 1. The first loading assembly lifts the arranged steel pipes 2, allowing them to fall onto the first support wheels 4, where they are supported. The rotation of the first support wheels 4 also reduces the resistance to the advancement of the steel pipes 2, facilitating the process. The feeding module is slidably connected to the frame 1. When the steel pipes 2 fall onto the first support wheels 4, the movement of the feeding module drives the steel pipes 2 toward the positioning assembly.

[0039] Further optimization scheme, the feeding module includes a feeding block 5 arranged on the frame 1, and a first pressing frame 8 for pressing the steel pipe 2 is provided on the feeding block 5. The feeding block 5 feeds the steel pipe 2 into the positioning assembly through the first pressing frame 8. A feeding motor 7 is provided on the feeding block 5, and the output shaft of the feeding motor 7 is engaged and triggered by a feeding rack 6 provided on the frame 1 through a gear, thereby enabling the feeding block 5 to slide on the frame 1; a first pressing frame 8 extending toward the steel pipe 2 is fixed on the feeding block 5, and the middle part of the first pressing frame 8 is rotatably connected to the feeding block 5, one end of which is in contact with the steel pipe 2 through the first pressing block 10, and the other end is fixed to the movable end of the first pressing push rod 9 installed on the feeding block 5. When the steel pipe 2 is placed in place, the first pressing push rod 9 extends, pushing the end of the first pressing frame 8 to rise, thereby pressing it on the steel pipe 2, achieving the fixation of the steel pipe 2, so that the movement of the feeding block 5 can drive the movement of the steel pipe 2.

[0040] To further optimize the solution, a retrieving rack 11 corresponding to the discharging assembly is provided on one side of the frame 1. A retrieving arm 12 that can be lifted and lowered is provided on the retrieving rack 11. A transfer claw 13 for grabbing the welded steel pipe 2 is provided at the bottom end of the retrieving arm 12. The retrieving rack 11 is provided in correspondence with the discharging assembly. When the steel pipe 2 after the welder enters the discharging assembly, the transfer motor 14 on the retrieving rack 11 engages with the transfer rack 15 through the gear, and the retrieving arm 12 can be raised and lowered on the retrieving rack 11, driving the transfer claw 13 to descend, grab the steel pipe 2, and then grab the steel pipe 2 and transfer it to the next process.

[0041] A further optimization scheme involves a discharge assembly comprising second support wheels 16 rotatably connected to the frame 1. The welded steel pipe 2 lands on a plurality of these second support wheels 16. A traction module is provided on the frame 1 for pulling the welded steel pipe 2. Driven by the feed block 5, the welded steel pipe 2 passes through the positioning assembly before landing on the second support wheels 16, reducing the forward resistance of the steel pipe 2. The traction module slides on the frame 1, pulling the end of the steel pipe 2 forward, allowing the steel pipe 2 to advance and enter the next process.

[0042] A further optimized solution is provided, in which the traction module includes a traction block 17 slidably mounted on the frame 1. The traction block 17 is provided with a traction frame 20 for traction of the steel pipe 2, which is used to traction the welded steel pipe 2. A traction motor 18 is mounted on the traction block 17. The output end of the traction motor 18 is meshed with a traction rack 19 on the frame 1 through a gear for transmission. The middle portion of the traction frame 20 on the traction block 17 is rotatably connected to the traction block 17, and one end is in transmission connection with a second pressing push rod 21 provided on the traction block 17. When the second pressing push rod 21 is extended or retracted, it drives the second pressing block 22 to press and release against the steel pipe 2. Thus, when the traction block 17 moves, the steel pipe 2 can be driven to move.

[0043] A further optimization scheme includes a positioning assembly including a positioning plate 23 corresponding to the first support wheel 4. Two symmetrically arranged positioning brackets 24 are movably mounted on the positioning plate 23. The two positioning brackets 24 are used to secure the steel pipe 2. The positioning plate 23 is located below the steel pipe 2. The two positioning brackets 24 slide on the positioning plate 23. The extension and retraction of the positioning telescopic rod 25 drives the positioning brackets 24 to position the steel pipe 2, preventing deviation during positioning and welding of the U-shaped member 3.

[0044] In a further optimization, the welding assembly includes welding guns 26 mounted on a positioning frame 24. Two welding guns 26 weld the two sides of the U-shaped member 3 to the surface of the steel pipe 2. Two corresponding welding guns 26 are located on the two sides where the U-shaped member 3 contacts the steel pipe 2. When the positioning frame 24 clamps the steel pipe 2, the welding guns 26 also contact the joint. Then, as the steel pipe 2 moves forward, the steel pipe 2 and the U-shaped member 3 are welded.

[0045] In a further optimized solution, the second loading assembly includes a loading rack 27 provided on the frame 1, and a loading clamp 28 is interactively provided on the loading rack 27 for picking up the U-shaped piece 3 and transferring it to the steel pipe 2. The loading clamp 28 on the loading rack 27 slides, and then can reciprocate to pick up the U-shaped piece 3 and place the U-shaped piece 3 on the steel pipe 2. At the same time, it can be fixed during welding to avoid dislocation caused by welding.

[0046] Furthermore, the loading clamp 28 of this embodiment is retractable, and a mechanical claw that can be opened is provided at its bottom end to grab the U-shaped part 3.

[0047] A further optimized solution is that the first loading assembly includes a mounting plate 29 provided at the bottom end of the frame 1, on which a loading telescopic rod 30 is mounted. The output end of the loading telescopic rod 30 is transmission-connected to a loading plate 31 for lifting the steel pipe 2 and placing it onto the first support wheel 4. The mounting plate 29 is provided below the frame 1, and the platform for placing the steel pipe 2 is tilted, so that the steel pipe 2 can continuously move toward the feed block 5 and above the loading plate 31. During loading, the loading telescopic rod 30 pushes the loading plate 31 upward, pushing up the steel pipe 2, and then dropping it onto the first support wheel 4.

[0048] Furthermore, an annular groove is formed on the outer wall of the first supporting wheel 4 and the second supporting wheel 16 for positioning the steel pipe 2 to prevent the steel pipe 2 from shaking.

[0049] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0050] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
