[0002] Before welding pipes, the tungsten needle must be aligned with the weld seam. Because accurate weld seam alignment directly impacts weld quality, the operator must visually confirm each alignment. This is particularly challenging in confined spaces, and some locations require a flashlight for clarity.

[0003] With the existing pipe bending welding equipment on the market, when welding pipes of the same specification, the operator has to re-align the weld every time a pipe is replaced, which makes the operation difficult for the operator and reduces production efficiency. Utility Model Content

[0004] In view of the problem that the operator has to re-align the weld every time a bend is replaced in the existing bend welding equipment, which is difficult for the operator to operate and has low production efficiency, the purpose of the utility model is to provide a welding equipment, including a base; a clamping part, which is arranged on the base and is used to clamp the pipe to be welded; and a bend positioning part, which is arranged on the base and is located on one side of the clamping part and is used to position the bend.

[0005] Furthermore, the bend pipe positioning member includes a bend pipe positioning support plate and a support plate locking member; wherein, the position of the bend pipe positioning support plate can be adjusted on the base to accommodate bends of different specifications; the support plate locking member is used to lock the bend pipe positioning support plate and the base after the position of the bend pipe positioning support plate is determined.

[0006] Furthermore, the bend pipe positioning support plate is slidably arranged on the base, and the support plate locking member is a screw arranged on the bend pipe positioning support plate.

[0007] Furthermore, a guide rail is provided on the base, and the bend pipe positioning member also includes a slider, which is fixedly connected to one end of the bend pipe positioning plate away from the clamping portion. The slider can slide along the guide rail to guide the sliding of the bend pipe positioning plate.

[0008] Furthermore, there are two guide rails, and the two guide rails are arranged in parallel on the base.

[0009] Furthermore, a guide rail mounting block is provided on the base, and the guide rail is mounted on the base through the guide rail mounting block, so that the slider is suspended on the base.

[0010] Furthermore, the guide rail mounting block includes a guide rail mounting block one and a guide rail mounting block two, the guide rail mounting block one is located on the side of the guide rail away from the clamping portion, and the guide rail mounting block two is located on the side of the guide rail close to the clamping portion; wherein, the slider is provided with a first opening, and the guide rail mounting block two is arranged in the first opening to limit the sliding distance of the slider.

[0011] Furthermore, a slide rail fixing hole is provided on the side of the guide rail mounting block, and a slide rail fixing member is installed into the slide rail fixing hole to fix the guide slide rail on the guide rail mounting block; wherein, a second mounting hole corresponding to the slide rail fixing hole is provided on the side of the slider, and the aperture of the second mounting hole is larger than the aperture of the slide rail fixing hole.

[0012] Furthermore, the back plate locking member includes: a hand-held portion and a locking body, wherein the hand-held portion is arranged at an end of the locking body away from the base, wherein the locking body passes through the slider to lock the slider and the base.

[0013] Furthermore, the backrest locking member also includes: a limiting member, which is connected to the end of the locking body away from the handheld part; wherein, the limiting member is located at the end of the slider close to the base, and is used to increase the locking force between the slider and the base.

[0014] Technical effects and advantages of this utility model:

[0015] 1. By arranging a bend locating piece for positioning the bend on one side of the clamping part, when welding bends of the same specification, the operator only needs to align the tungsten needle with the weld during the first welding, and then adjust the bend locating piece to a position leaning against the bend. Then, subsequent bends of the same specification can be positioned according to the bend locating piece. The operator does not need to repeat the weld operation, which can reduce the operator's operating difficulty and improve production efficiency.

[0016] 2. Compared with setting multiple mounting holes on the base, slidably setting the elbow positioning piece on the base can improve the applicability of the welding equipment and meet different specifications rather than only meeting a few specific specifications of the pipes to be welded.

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0024] See also Figure 1 , which is a structural diagram of a welding device provided by the present invention. Figures 1 to 4 The welding device, for example, includes a base 10, a clamping portion 20, and a pipe bend positioning member 30. The clamping portion 20 is provided on the base 10 for clamping the pipe to be welded; the pipe bend positioning member 30 is provided on the base 10 and is located on one side of the clamping portion 20 for positioning the pipe bend.

[0025] It can be understood that by providing a bend positioning piece 30 for positioning the bend on one side of the clamping portion 20, when welding bends of the same specification, the operator only needs to align the tungsten needle with the weld during the first welding, and then adjust the bend positioning piece 30 to a position leaning against the bend. Then, subsequent bends of the same specification can be positioned according to the bend positioning piece 30, and the operator does not need to repeat the weld operation, thereby reducing the operator's operating difficulty and improving production efficiency.

[0026] For example, the pipes to be welded include pipe 1 201 and pipe 2 202, where pipe 1 201 is a bent pipe. After the weld seam and the tungsten needle are aligned, the clamping portion 20 clamps pipe 1 201 and pipe 2 202 together. The elbow locator 30 is then adjusted to a position that abuts the elbow and supports it. Subsequent elbows of the same specification can be aligned with the weld seam using the elbow locator 30, eliminating the need to repeat the weld seam alignment process.

[0027] Furthermore, the elbow positioning member 30 includes, for example, an elbow positioning support plate 31 and a support plate locking member 32. The elbow positioning support plate 31 is adjustably positioned on the base 10 to accommodate elbows of varying sizes. The support plate locking member 32 is used to lock the elbow positioning support plate 31 with the base 10 after the position of the elbow positioning support plate 31 is determined, preventing relative movement between the elbow positioning support plate 31 and the base 10. This ensures that the weld seams of the subsequently welded pipes are aligned, preventing the weld seam from shifting due to movement of the elbow positioning support plate 31 and affecting weld quality.

[0028] For example, the base 10 is provided with multiple mounting positions for the elbow positioning plate 31, each corresponding to a different specification of the elbow to be welded. When the specification of the elbow to be welded changes, the plate locking member 32 is loosened to release the locking member 32 between the elbow positioning plate 31 and the base 10, and the position of the elbow positioning plate 31 is readjusted. After the position of the elbow positioning plate 31 is re-determined, the plate locking member 32 is tightened again to re-lock the elbow positioning plate 31 with the base 10.

[0029] Preferably, a guide rail 41 is provided on the base 10, and the elbow positioning member 30 further includes a slider 33. The slider 33 is fixedly connected to the end of the elbow positioning plate 31 away from the clamping portion 20. The slider 33 can slide along the guide rail 41, so that the elbow positioning plate 31 can slide along the guide rail 41 through the slider 33, thereby achieving the guiding effect of the guide rail 41 on the elbow positioning plate 31.

[0030] It can be understood that compared with setting multiple mounting holes on the base 10, slidably setting the elbow positioning member 30 on the base 10 can improve the applicability of the welding equipment and meet different specifications rather than only meeting a few specific specifications of the pipes to be welded.

[0031] Furthermore, there are two guide rails 41, which are arranged in parallel on the base 10. Compared with only one guide rail 41, the provision of two parallel guide rails 41 can make the sliding of the slider 33 more stable.

[0032] Furthermore, a guide rail mounting block 42 is provided on the base 10. The guide rail 41 is mounted on the base 10 via two guide rail mounting blocks 42. The slider 33 is suspended on the base 10. When the slider 33 slides along the guide rail 41, no sliding friction is generated between the lower end surface of the slider 33 and the upper end surface of the base 10, thereby ensuring smoother sliding of the slider 33.

[0033] Furthermore, the guide rail mounting block 42 includes a first guide rail mounting block 421 and a second guide rail mounting block 422. The first guide rail mounting block 421 is located on the side of the guide rail 41 away from the clamping portion 20, while the second guide rail mounting block 422 is located on the side of the guide rail 41 closer to the clamping portion 20. The slider 33 is provided with a first opening 331, and the second guide rail mounting block 422 is disposed within the first opening 331. When the slider 33 slides along the guide rail 41, the second guide rail mounting block 422 and the first opening 331 limit the sliding distance of the slider 33. The maximum sliding distance of the slider 33 is the length of the first opening 331 along the sliding direction of the slider 33.

[0034] Furthermore, the guide rail mounting block 42 has a rail fixing hole 423 on its side. For example, if the guide rail 41 has a circular cross-section, after the guide rail 41 is mounted on the guide rail mounting block 42, a rail fixing member is required to secure the guide rail 41 to prevent relative rotation between the guide rail 41 and the guide rail mounting block 42. For example, the guide rail mounting block 42 has a rail fixing hole 423 on its side, and the rail fixing member is inserted into the rail fixing hole 423 to secure the guide rail 41 to the guide rail mounting block 42. In one specific embodiment, the side surfaces of both the guide rail mounting block 1 421 and the guide rail mounting block 2 422 have rail fixing holes 423.

[0035] For example, a second mounting hole 332 is formed on the side of the slider 33, corresponding to the rail fixing hole 423. The diameter of the second mounting hole 332 is larger than that of the rail fixing hole 423. When the guide rail 41 is fixed to the second rail mounting block 422 using the rail fixing member, the rail fixing member must first pass through the second mounting hole 332, as the second rail mounting block 422 is disposed within the first opening 331. By making the diameter of the second mounting hole 332 larger than that of the rail fixing hole 423, the rail fixing member can be more easily installed in the second rail mounting block 422, thereby improving assembly efficiency.

[0036] Furthermore, the back plate locking member 32 includes, for example, a hand-held portion 321 and a locking body 322. The locking body 322 is screwed onto the slider 33, and is used to lock the slider 33 and the base 10, thereby preventing relative sliding between the slider 33 and the base 10 and ensuring welding quality. The hand-held portion 321 is provided at the end of the locking body 322, and the operator can loosen or tighten the locking body 322 by holding the hand-held portion 321 and rotating it. For example, the back plate locking member 32 is a star-shaped screw. Compared to setting the shape of the hand-held portion 321 to a circle, the star-shaped shape is more ergonomic and less prone to slipping and rotation problems.

[0037] Furthermore, the back plate locking member 32 also includes, for example, a stopper 323. The stopper 323 is connected to the end of the locking body 322 away from the handle 321 and is located at the end of the slider 33 closer to the base 10. The cross-section of the stopper 323 is larger than that of the locking body 322. This increases the contact area between the slider 33 and the base 10, thereby increasing the locking force between the slider 33 and the base 10. Furthermore, the stopper 323 prevents the locking body 322 from falling off the slider 33.
