DETAILED DESCRIPTION
[0026] In order to make the purpose, technical scheme and advantages of the embodiment of the application more clear, the embodiments of the application are described in detail below with reference to the drawings, but the described embodiments of the application are part of the embodiments of the application, not all the embodiments of the application.
[0027] The embodiment of the application provides a pipe welding auxiliary device, as shown in the figure, comprising a first rotating roller 1, a second rotating roller 3, a linear mechanism 7 and the like. Figures 1-8 The embodiment of the application provides a pipe welding auxiliary device, as shown in the figure, comprising a first rotating roller 1, a second rotating roller 3, a linear mechanism 7 and the like.
[0028] Specifically, the first rotating roller 1 is a pair of rollers arranged in the horizontal direction and rotatably connected to the top of a pair of first supporting plates 101. The bottom of each first supporting plate 101 is provided with a strip-shaped vertical plate 2 parallel to the first supporting plate 101. An opening is formed through the two sides of the strip-shaped vertical plate 2, and a guide block 6 is arranged in the opening. An upper guide groove 201 is formed between the top of the guide block 6 and the wall of the opening. The height of the upper guide groove 201 gradually increases and then gradually decreases from one end to the other end. Specifically, the upper guide groove 201 can be in an inverted V shape or an arc shape. The two ends of the upper guide groove 201 are located directly below a pair of first rotating rollers 1, and the heights of the two ends of the upper guide groove 201 are matched. The highest point of the upper guide groove 201 is located between the two pairs of first rotating rollers 1. The second rotating roller 3 is a pair of rollers rotatably connected to the top of a pair of second supporting plates 301. The pair of second supporting plates 301 are arranged between the pair of strip-shaped vertical plates 2. A vertical sliding groove 3011 is formed in the inner side of each second supporting plate 301. An outer side of each second supporting plate 301 is provided with a guide column 3012. The two guide columns 3012 are slidably arranged in the pair of upper guide grooves 201. When the guide column 3012 is at the highest point of the upper guide groove 201, the top of the second rotating roller 3 is higher than the top of the first rotating roller 1, so that the pipe 8 on the second rotating roller 3 does not contact the first rotating roller 1. When the guide column 3012 is at either end of the upper guide groove 201, the top of the second rotating roller 3 is lower than the top of the first rotating roller 1 by a predetermined distance. When the pipe 8 abuts against the top of the first rotating roller 1, the second rotating roller 3 is below the pipe 8. The pipe 8 on the first rotating roller 1 can be lifted and transferred by slightly moving the second rotating roller 3 upward. A linear mechanism 7 is arranged between the pair of second supporting plates 301. The moving direction of the movable end of the linear mechanism 7 is parallel to the length direction of the strip-shaped vertical plate 2. The movable end of the linear mechanism 7 is provided with a sliding block 7011 on each side. The two sliding blocks 7011 are slidably connected to the sliding grooves 3011, respectively.
[0029] In actual use, a pipe conveying device 8 is arranged at one end of the strip-shaped vertical plate 2, which can be a power roller bed for conveying the pipe 8, and the top height of the power roller bed is matched with the top height of the first rotating roller 1, and then the movable end of the linear mechanism 7 is controlled to move to the end of the upper guide slot 201 close to the power roller bed, and when the pipe 8 is conveyed to the pair of first rotating rollers 1 closest to the power roller bed by the power roller bed, the movable end of the linear mechanism 7 is controlled to move to the end of the upper guide slot 201 away from the power roller bed, and in the process, the pair of second rotating rollers 3 is initially arranged between the pair of first roller beds close to the power roller bed, and the movable end of the linear mechanism 7 pushes the pair of second supporting plates 301 below the second rotating roller 3 to move to the other pair of first rotating rollers 1 through the sliding block 7011, and because the guide column 3012 is arranged in the upper guide slot 201, the guide column 3012 is first moved upward along the upper guide slot 201 to move the second supporting plate 301 and the second rotating roller 3 upward to push the pipe 8 above to be separated from the first rotating roller 1, and then the guide column 3012 is moved downward along the upper guide slot 201 to move the second rotating roller 3 below the pair of first rotating rollers 1 away from the power roller bed to realize the transfer of the pipe 8, and when the subsequent pipe 8 on the power roller bed reaches the first rotating roller 1 closest to it, the two pipes 8 can be aligned, and finally the two pipes 8 are close to each other to be welded, and in the welding process, when the pipe 8 is rotated, the pipe 8 and the first rotating roller produce rolling friction to reduce the friction force on the pipe 8, and after the welding is completed, the pipe 8 is removed, the movable end of the linear mechanism 7 is reset, and the above steps are repeated to weld the subsequent pipe 8.
[0030] Preferably, referring to Figure 2 、 Figure 3The bottom of the guide block 6 and the wall of the opening bottom are provided with a horizontal lower guide groove 202, and the two ends of the guide block 6 are respectively arranged in the wall of the two ends of the opening, so that the guide column 3012 can fall from the two ends of the upper guide groove 201 into the lower guide groove 202. The outer side of the guide block 6 is connected to the outer side of the same side of the strip-shaped vertical plate 2 through a connecting plate 601, and one end of the guide block 6 is hinged with a guide plate 602. The rotation axis of the guide plate 602 is perpendicular to the strip-shaped vertical plate 2. When the guide column 3012 moves to one end of the lower guide groove 202 close to the guide plate 602, the bottom of the guide plate 602 abuts against the bottom of the lower guide groove 202, so that the guide column 3012 can move along the top surface of the guide plate 602 into the upper guide groove 201 after being subjected to horizontal pushing force. In actual use, the power roller is arranged at one end of the strip-shaped vertical plate 2 close to the guide plate 602. When the movable end of the linear mechanism 7 drives the guide column 3012 on the second support plate 301 to move to one end of the upper guide groove 201 away from the guide plate 602, the guide column 3012 will move downward into the lower guide groove 202 due to its own gravity. At this time, the movable end of the linear mechanism 7 can be controlled to reset, so that the guide column 3012 reaches one end of the lower guide groove 202 close to the power roller, and prepares for the next transfer of the pipe 8. The movable end of the linear mechanism 7 can be reset only after the pipe 8 is welded and unloaded, which can further improve the alignment efficiency of the pipe 8.
