Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, and more specifically, to a continuous automated pipe welding equipment. Background Technology

[0002] In the field of pipe welding, with the continuous improvement of industrial production requirements for efficiency and quality, continuous automated welding technology has become a key direction for industry development.

[0003] Currently, pipe welding equipment on the market has achieved the function of welding pipes to a certain extent, but there are still significant technical defects in the continuous automated processing of welded pipes, which seriously restricts the efficiency and quality of welding operations.

[0004] In actual production, the dimensions and specifications of pipe fittings to be welded often vary, and parameters such as diameter and length may differ significantly between different batches or application scenarios. However, existing equipment typically employs a fixed clamping and feeding mechanism, which has limited clamping range and adjustment precision, making it difficult to flexibly fine-tune according to changes in pipe fitting dimensions. When encountering pipe fittings whose dimensions exceed the equipment's preset range, manual adjustments to the clamping mechanism or replacement with specialized clamps are often required. This not only increases operational difficulty and labor intensity but also prolongs production preparation time and reduces production efficiency. Moreover, because the clamping mechanism cannot precisely adapt to changes in pipe fitting dimensions, problems such as pipe loosening and displacement can easily occur during clamping, further affecting the stability and quality of the welding. Utility Model Content

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] Example 1 includes a housing 1 and a welding device 2 disposed beside the housing 1. The automated pipe welding equipment also includes a continuous feeding mechanism 3 and a rotating abutment mechanism 4. The continuous feeding mechanism 3 is disposed on the top of the housing 1 and includes a moving part 31, a fixing ring 32, a mounting frame 33, and a rotating abutment part 34. The moving part 31 is slidably disposed on the top of the housing 1. The fixing ring 32 is disposed on the top of the moving part 31, and the end face of the fixing ring 32 has a circular opening for the pipe to be welded to pass through. The mounting frame 33 is disposed on the top of the moving part 31 and is located beside the fixing ring 32. The rotating abutment part 34 is slidably disposed on the top of the mounting frame 33 and is used to abut against the side of the pipe to be welded. The rotating abutment mechanism 4 is disposed on the top of the housing 1.

[0029] To address the challenges of continuous, horizontally progressive welding of pipe fittings in existing technologies, and the inconvenience of adjusting the lateral rotational contact of the pipe fittings, this embodiment employs a pair of rotating contact parts 34. First, the pipe fitting to be welded is placed beside the pair of rotating contact parts 34 using a robotic arm. Then, the pair of rotating contact parts 34 move closer together until they have contacted both sides of the pipe fitting and stop moving. Next, the pair of rotating contact parts 34 rotate, allowing the pipe fitting to be welded to pass through a circular opening on the end face of the fixing part and move to the area below the welding device 2 for welding. Furthermore, as the pair of rotating contact parts 34 moves the pipe fitting to the area below the welding device 2, they can make fine adjustments based on changes in the pipe fitting's dimensions, improving the adaptability of the pipe fitting clamping and loading operation.

[0030] See Figures 3-5 The continuous feeding mechanism 3 also includes a first mounting plate 35, a first guide rail 36, and a first linear driver 37; the first mounting plate 35 is a pair and is respectively disposed on the top of the housing 1, and both of the first mounting plates 35 are located below the moving part 31; the first guide rail 36 is a pair and is respectively disposed between the pair of first mounting plates 35, and both of the first guide rails 36 are in clearance fit with the bottom of the moving part 31; the first linear driver 37 is disposed on the side of the first mounting plate 35, and the output end of the first linear driver 37 is connected to the moving part 31.

[0031] Specifically, the output end of the first linear actuator 37 is equipped with a lead screw threadedly connected to the moving part 31. When the first linear actuator 37 is activated, it drives the moving part 31 to move horizontally along the first guide rail 36. To address the issue of welding short pipe fittings, the moving part 31 can move the fixed part and the pipe fitting closer to the welding device 2, thereby further moving the pipe fitting below the welding device 2. This achieves continuous rotary feeding of the pipe fittings.

[0032] See Figure 4 and Figure 5 The continuous feeding mechanism 3 also includes a limiting plate 38, a first bearing sleeve 39, and a rotary driver 391; the limiting plate 38 has a pair and is respectively disposed on the side of the mounting frame 33, and the top of the pair of limiting plates 38 is provided with a stroke groove; the first bearing sleeve 39 is slidably disposed on the top of the limiting plate 38; the rotary driver 391 is disposed on the top of the first bearing sleeve 39, and the output end of the rotary driver 391 is connected to the rotary abutment part 34.

[0033] Specifically, in this embodiment, the rotary driver 391 is connected to the first bearing sleeve 39 via a coupling, and the output end of the rotary driver 391 is connected to the rotary abutment part 34. When the rotary driver 391 is started, it can drive the rotary abutment part 34 to rotate through the first bearing sleeve 39.

[0034] See Figures 4-6 The continuous feeding mechanism 3 also includes a second bearing sleeve 392, a limiting part 393, and a telescopic cylinder 394; the second bearing sleeve 392 is slidably disposed at the bottom of the limiting plate 38, and the second bearing sleeve 392 is located below the rotating abutment part 34; there is a pair of limiting parts 393 respectively disposed on the side of the mounting frame 33, and the pair of limiting parts 393 are clearance-fitted with the second bearing sleeve 392; there is a pair of telescopic cylinders 394 respectively disposed at the top of the mounting frame 33, and the output ends of the pair of telescopic cylinders 394 are connected to the first bearing sleeve 39.

[0035] Specifically, to ensure the movement of the rotating abutment part 34, the bottom of the rotating abutment part 34 is rotatably connected to the second bearing sleeve 392. When the telescopic cylinder 394 is activated, it can drive the first bearing sleeve 39 to move. When the first bearing sleeve 39 moves, it can drive the second bearing sleeve 392 to move synchronously along the clearance fit limiting part 393. Thus, the position of the rotating abutment part 34 can be moved stably.

[0036] See Figure 2The rotating contact mechanism 4 includes a mounting part 41, a first rotating part 42, and a second rotating part 43. The mounting part 41 has a pair and is respectively disposed on the top of the housing 1, and both mounting parts 41 are located below the welding device 2. The first rotating part 42 has a pair and is respectively disposed on the side of the mounting part 41. The second rotating part 43 has a pair and is respectively rotatably disposed on the side of the mounting part 41.

[0037] Specifically, in order to achieve the rotational grinding of the pipe fitting to be welded, when the pipe fitting to be welded is moved to the bottom of the welding device 2, the pipe fitting to be welded can be abutted by the first rotating part 42 and the second rotating part 43 respectively.

[0038] See Figure 2 The rotating abutment mechanism 4 also includes a rotating motor 44 and a connecting rod 45; the rotating motor 44 is disposed on the side of the mounting part 41, and the output end of the rotating motor 44 is connected to the first rotating part 42; the connecting rod 45 is disposed on the side of the mounting part 41, and the two ends of the connecting rod 45 are respectively connected to a pair of first rotating parts.

[0039] Specifically, when the rotary motor 44 starts, it can drive a pair of first rotating parts 42 to rotate through the connecting rod 45. When the first rotating part 42 rotates, it can rotate the pipe to be welded located at the top between the first rotating part 42 and the second rotating part 43, thereby realizing the rotary welding of the pipe to be welded.

[0040] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
