[0024] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 7 The image shows an auxiliary welding device according to the first embodiment of the present invention, including a fixing component 20 rotatably connected to the steel pipe 10 to be welded, a longitudinal sliding component 30 disposed on the fixing component 20, a transverse sliding component 40 connected to the longitudinal sliding component 30, and a welding component 50 connected to the transverse sliding component 40. The longitudinal sliding component 30 is rotatably connected to the fixing component 20, the transverse sliding component 40 is rotatably connected to the longitudinal sliding component 30, and the welding component 50 is rotatably connected to the transverse sliding component 40. The fixing component 20 is detachably connected to the steel pipe 10 to be welded.

[0029] Understandably, by setting the fixing component 20, when welding the steel pipe is required, the fixing component 20 is rotated and positioned on the steel pipe 10 to be welded. Then, the longitudinal sliding component 30 and the transverse sliding component 40 are adjusted to adjust the longitudinal and transverse positions of the welding component 50 respectively. During this period, the position of the welding component 50 can also be further adjusted by adjusting the rotational positions of the longitudinal sliding component 30 and the fixing component 20, the transverse sliding component 40 and the longitudinal sliding component 30, and the welding component 50 and the transverse sliding component 40. The aim is that when the fixing component 20 is rotated around the steel pipe, the point of action is always facing the steel pipe. In this way, we can weld the steel pipe while rotating the fixing component 20, which greatly improves the welding accuracy.

[0030] Specifically, in this embodiment, the fixing component 20 includes a housing, which includes a bent portion 21 and an extension portion 22 integrally formed with the bent portion 21. The bent portion 21 is recessed with a receiving groove 27, and the extension portion 22 is provided with a receiving hole 29. The fixing component 20 also includes a plurality of contact posts 28 arranged in an arc shape in the receiving groove 27, and an adjustment structure that slides along the receiving hole 29. The adjustment structure includes a U-shaped shell 23, a threaded rod 25 rotatably disposed in the U-shaped shell 23, an adjustment knob 24 fixedly connected to the threaded rod 25, and a pulley 26 rotatably disposed at one end of the U-shaped shell 23 near the contact post 28. The receiving hole 29 is provided with a mounting block 291 threadedly connected to the threaded rod 25. The steel pipe 10 to be welded is located in the receiving space formed between the contact post 28 and the pulley 26.

[0031] Understandably, when the fixing component 20 needs to be rotatably mounted on the steel pipe, the steel pipe is placed between the bend 21 and the extension 22. Depending on the diameter of the steel pipe, it is pressed against the appropriate two contact posts 28. Then, by rotating the adjusting knob 24, the threaded rod 25 is moved along the mounting block 291 towards the steel pipe. The threaded rod 25 rotates forward, while the U-shaped shell 23, rotatably connected to the threaded rod 25, moves linearly with its inner wall conforming to the receiving hole 29, until the pulley 26 on the U-shaped shell 23 tightly presses against the outer wall of the steel pipe. This allows the contact posts 28 and the pulley 26 to be horizontally pressed and fixed onto the steel pipe, enabling only horizontal rotation and preventing lateral and longitudinal movement. There are four contact posts 28 arranged in an arc shape to accommodate steel pipes of different sizes. The steel pipe only needs to rest against two contact posts 28.

[0032] Furthermore, the longitudinal sliding assembly 30 includes a first fixing rod 31 fixed to the extension portion 22 and a first fixing block 34 detachably disposed on the first fixing rod 31. The first fixing block 34 has a first fixing hole 32 and a second fixing hole 36 at both ends. The first fixing rod 31 is located in the first fixing hole 32. The first fixing block 34 extends outward from the first fixing hole 32 to form a first slot 33, and the second fixing block 34 extends outward from the second fixing hole 36 to form a second slot 37. The first fixing block 34 has a first bolt 35 and a second bolt 38 at both ends for penetrating the first slot 33 and the second slot 37, respectively. The transverse sliding assembly 40 includes a second fixing rod 41 detachably disposed in the second fixing hole 36 and a second fixing block 44 detachably disposed on the second fixing rod 41. The second fixing block 44 is provided with a third fixing hole 42 and a fourth fixing hole 46 at its two ends respectively. The second fixing rod 41 is located in the third fixing hole 42. The second fixing block 44 extends outward from the third fixing hole 42 to form a third slot 43. The second fixing block 44 extends outward from the fourth fixing hole 46 to form a fourth slot 47. The two ends of the second fixing block 44 are provided with a third bolt 45 and a fourth bolt 48 for penetrating the third slot 43 and the fourth slot 47 respectively. The welding assembly 50 includes a third fixing rod 51 detachably provided in the fourth fixing hole 46, an annular buckle 52 connected to the end of the third fixing rod 51 away from the second fixing block 44, an air inlet 53 fixed in the annular buckle 52, and a welding torch 55 connected to the air inlet 53.

[0033] Understandably, when the position of the welding torch 55 needs to be adjusted, the first fixing rod 31 is positioned in the first fixing hole 32 in the first fixing block 34, and the longitudinal height and horizontal rotation position are adjusted. Then, the first bolt 35 is threadedly connected to the first fixing block 34. The first bolt 35 passes through the first slot 33 from one end of the first fixing block 34 and is threaded to the other end of the first fixing block 34 until the nut of the first bolt 35 abuts against the first fixing block 34. This tightens the first fixing blocks 34 at both ends of the first slot 33, thereby allowing the first fixing hole 32 to lock the first fixing rod 31, thus fixing the longitudinal length. Then, the second fixing rod 41 passes through the second fixing hole 36 on the first fixing block 34 and the third fixing hole 42 on the second fixing block 44. First, adjust the relative position and rotation angle between the second fixing block 44 and the second fixing rod 41, and then clamp the second fixing hole 36 and the third fixing hole 42 with the second bolt 38 and the third bolt 45 respectively to fix the second fixing rod 41. Next, pass the third fixing rod 51 through the third fixing hole 42 on the second fixing block 44, adjust the relative position and rotation angle between the second fixing block 44 and the third fixing rod 51, and clamp the fourth fixing hole 46 with the fourth bolt 48 to fix the third fixing rod 51. Finally, fix the air inlet cylinder 53 to the annular buckle 52 on the third fixing rod 51. In actual installation, the air inlet cylinder 53 can be fixed to the annular buckle 52 first, and the rest of the structure can be adjusted according to the position of the welding torch 55, which is more convenient.

[0034] Preferably, the free ends of the first fixing rod 31, the second fixing rod 41, and the third fixing rod 51 are all provided with anti-detachment sleeves 60.

[0035] Understandably, by setting anti-disengagement sleeves 60 at the free ends of the first fixing rod 31, the second fixing rod 41 and the third fixing rod 51, the fixing rods can be prevented from being pulled out when adjusting the position of the welding torch 55, thus avoiding affecting the installation efficiency.

[0036] Furthermore, the welding assembly 50 also includes an air inlet pipe 54 located at the end of the air inlet cylinder 53 away from the welding torch 55.

[0037] Understandably, the air inlet pipe 54 can be connected to an argon cylinder.

[0038] In use, the steel pipe is clamped between the contact post 28 and the pulley 26, and then the welding torch 55 is started. While welding, the end of the extension 22 is manually moved so that the relative distance between the torch head of the welding torch 55 and the steel pipe is always constant regardless of the angle, thereby greatly improving the welding accuracy.

[0039] In summary, the auxiliary welding device in the above embodiments of this utility model can weld steel pipes while rotating the fixing component, which greatly improves the welding accuracy.
