[0022] In the following description, embodiments of the welding device for connecting pipes of the ventilator in the steel structure workshop of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a welding device for connecting pipes of a ventilator in a steel structure factory, comprising a guide rail 1. A linear slide block 2 is slidably connected to the surface of the guide rail 1. An operating rod 9 is fixedly connected to the top of the linear slide block 2. A welding machine 3 is installed on the front side of the linear slide block 2. Support components 4 are provided on both sides of the bottom of the guide rail 1. Each support component 4 includes a sliding tube 41 fixedly connected to the bottom of the guide rail 1. A support tube 42 is slidably connected to the surface of the sliding tube 41. A base 43 is welded to the bottom of the support tube 42. Foot 7 is fixedly connected to both ends of the front side of the bottom of the base 43. Pulleys 8 are installed on both ends of the rear side of the bottom of the base 43. Through the cooperation of the foot 7 and the pulleys 8, the guide rail 1 can be positioned at rest, and the welding device can be moved quickly by the user, allowing the welding device to quickly reach the designated welding position and reducing the welding position calibration time. Bolts 44 are threaded to the top of the opposite sides of the two support tubes 42. Multiple threads are provided on the opposite sides of the two sliding tubes 41. Hole 45, one end of bolt 44 passes through the inner cavity of support tube 42 and is threaded into the inner cavity of threaded hole 45. Through the setting of support assembly 4, the sliding tube 41, support tube 42 and base 43 work together to support guide rail 1. At the same time, with the cooperation of bolt 44 and threaded hole 45, the working height of guide rail 1 can be adjusted, thereby allowing for preliminary adjustment of the welding height of welding machine 3. A fine adjustment assembly 5 is set on the front side of linear slide 2. The fine adjustment assembly 5 includes a sliding... The sliding frame 51 and the linear slide block 2 are provided with limiting grooves 53 at both ends of the front side, which are adapted to the sliding frame 51. A connecting plate 52 is welded to the front side of the sliding frame 51. The front side of the connecting plate 52 is fixedly connected to the welding machine 3 by bolts. A threaded rod 54 is rotatably connected to the bottom of the inner cavity of the sliding frame 51 through a bearing. The top end of the threaded rod 54 extends to the top of the sliding frame 51 and is fixedly connected to a handle. The linear slide block 2 is threadedly connected to the surface of the threaded rod 54. Laser emitters 6 are fixedly connected to both sides of the welding machine 3.

[0024] Working Principle: When using this utility model, the user first rotates the bolt 44, causing it to disengage from the inner cavity of the threaded hole 45. At this time, the support tube 42 and the sliding tube 41 slide relative to each other. The operating height of the guide rail 1 is adjusted according to the actual height of the welding connecting tube, adjusting it so that the welding machine 3 is close to the top of the connecting tube. Then, the bolt 44 is rotated back into the inner cavity of the current threaded hole 45 to limit and fix the operating height of the guide rail 1. Subsequently, the user turns on the laser emitter 6, causing the laser beam of the laser emitter 6 to irradiate the surface of the connecting tube. Then, the guide rail 1 is tilted so that the base 7 is lifted off the ground, leaving only the surface of the pulley 8 in contact with the ground. Pull the guide rail 1 back and forth, following the laser beam indication, until the laser beam coincides with the welding position. Keep the welding head of the welding machine 3 and the welding position on the same horizontal and vertical line. Then, the user rotates the handle at the top of the threaded rod 54, causing the threaded rod 54 to drive the sliding frame 51 to move downward through the pushing action of its surface threads. This allows the connecting plate 52 to drive the welding machine 3 to move downward. Finally, the user's welding head of the welding machine 3 contacts the welding position. Then, the user turns on the welding machine 3 and holds the operating lever 9 to slide the linear slide 2 left and right. Finally, the running welding machine 3, driven by the linear slide 2, performs linear welding on the welding position of the connecting pipe.

[0025] In summary, the welding device for the connecting pipe of the ventilator in this steel structure workshop, through the setting of the support component 4, provides high support for the guide rail 1. Then, through the cooperation of the guide rail 1, the linear slide 2 and the laser emitter 6, the welding machine 3 is calibrated for sliding horizontally. Finally, with the cooperation of the fine-tuning component 5 and the welding machine 3, the connection of the connecting pipe is horizontally welded, thus achieving the purpose of wide applicability to various sizes and calibrable welding positions.
