Description

Technical Field

[0001] This utility model relates to the field of pipe welding, specifically a welding device for ventilation ducts. Background Technology

[0002] Ventilation ducts are widely used in various fields, such as buildings and factories, as ventilation facilities in industrial and civil buildings. These duct systems are usually made of metal and require welding technology to connect multiple pipe sections into a whole to ensure smooth airflow and system stability.

[0003] Current welding equipment often struggles to adapt to ventilation ducts of various specifications and shapes; for example, it cannot weld square and round pipes simultaneously, which significantly limits the improvement of welding efficiency. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a ventilation duct welding device.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A ventilation duct welding device includes a frame with a linear slide table mounted on it. Protruding plates are fixedly connected to the middle of the front and rear side walls of the frame. A first linear slide table is fixedly connected between the tops of the two protruding plates. The upper part of the first linear slide table is slidably engaged with the bottom of a second linear slide table. The second linear slide table extends vertically, and an extension rod is provided on the front side wall of the second linear slide table. A welding torch is mounted at the front end of the extension rod. Slide rails are fixedly connected to the front and rear sides of the top of the frame. The tops of two slide rails are slidably engaged with the bottoms of four movable frames. Two movable frames are located on each side of the first linear slide table. The walls are equipped with four-jaw chucks. The four-jaw chucks on both sides of the linear slide are arranged in the same direction and opposite to each other. The upper part of the moving frame is ring-shaped. The upper inner side of the moving frame is equipped with a bearing. The bearing is sleeved with a connecting pipe. The moving frame is connected to the connecting pipe through the bearing. The left and right ends of the connecting pipe extend through the outside of the moving frame. The four-jaw chucks are fixedly connected to the opposite ends of the left and right connecting pipes. Gear 1 is fixedly sleeved on the outer wall of the right end of the rightmost connecting pipe. The right side wall of the rightmost moving frame is fixedly installed with a motor. Gear 2 is fixedly sleeved on the outer wall of the output shaft of the motor. Gear 2 meshes with gear 1.

[0007] Locking nuts are rotatably installed at both the front and rear ends of the bottom of the mobile frame, and the outer wall of the locking nut abuts against the outer wall of the slide rail.

[0008] The beneficial effects of this utility model are:

[0009] The present invention comprises a linear slide table 1 and a linear slide table 2, which can move up and down and back and forth. This allows the welding torch to be flexibly adjusted in position, thus making it compatible with various specifications of pipes. Whether it is a round pipe or a square pipe, a suitable welding position can be found for welding, which greatly improves the versatility of the device.

[0010] The motor, through the transmission of gears one and two, enables the pipe clamped by the four-jaw chuck to rotate. During welding, the rotation of the pipe allows the welding torch to remain in a relatively fixed position, facilitating welding for the operator and improving welding quality and efficiency.

[0016] like Figure 1-4As shown: A ventilation duct welding device includes a frame 1, on which a linear slide is mounted; protruding plates 2 are fixedly connected to the middle of the front and rear side walls of the frame 1, and a linear slide 3 is fixedly connected between the tops of the two protruding plates 2. The upper part of the linear slide 3 is slidably engaged with the bottom of a second linear slide 4, which extends vertically. An extension rod 5 is provided on the front side wall of the second linear slide 4, and a welding torch 6 is provided at the front end of the extension rod 5. Slide rails 7 are fixedly connected to the front and rear sides of the top of the frame 1, and the tops of the two slide rails 7 are slidably engaged with the bottom of four movable frames 8. Two movable frames 8 are provided on each side of the linear slide 3, and four-jaw chucks 11 are provided on the side walls of the movable frames 8 on both sides of the linear slide 3. The four-jaw chucks 11 on both sides of the linear slide 3 are arranged in the same direction and opposite to each other. The upper part of the moving frame 8 is annular. A bearing 16 is provided on the inner side of the upper part of the moving frame 8. The bearing 16 is sleeved with the connecting pipe 12. The moving frame 8 is rotatably connected to the connecting pipe 12 through the bearing 16. The left and right ends of the connecting pipe 12 extend through the outer side of the moving frame 8. The four-jaw chucks 11 are fixedly connected to the opposite ends of the left and right connecting pipes 12. The right end of the rightmost connecting pipe 12 is fixedly sleeved with a gear 13. The right side wall of the rightmost moving frame 8 is fixedly installed with a motor 14. The output shaft of the motor 14 is fixedly sleeved with a gear 2 15. The gear 2 15 meshes with the gear 13.

[0017] Locking nuts 10 are rotatably installed at both the front and rear ends of the bottom of the movable frame 8, and the outer wall of the locking nut 10 abuts against the outer wall of the slide rail 7.

[0018] The motor 14 is a worm gear reducer motor and has a self-locking function.

[0019] Insert the pipe to be welded into the four-jaw chucks 11 on the left and right sides respectively. The pipe is clamped and fixed by the four-jaw chucks 11. By rotating the locking nut 10, the outer wall of the locking nut 10 is separated from the outer wall of the slide rail 7. At this time, the bottom of the moving frame 8 can slide freely on the slide rail 7. Adjust the distance between the left and right moving frames 8 according to the length of the pipe. After the pipe is in a suitable position, rotate the locking nut 10 again so that its outer wall abuts against the outer wall of the slide rail 7, thereby fixing the position of the moving frame 8 and ensuring that the pipe remains stable during the welding process.

[0020] Linear slide 3 and linear slide 4 together form a mechanism that can move up and down and back and forth. According to the specifications of the pipe to be welded, such as round pipe or square pipe, and the requirements of the welding position, the welding torch 6 is moved to the appropriate position for welding by controlling linear slide 3 and linear slide 4.

[0021] After a portion of the welding is completed, the two pipes are initially connected. The motor 14 is started, and the output shaft of the motor 14 drives the gear 15 to rotate. Since the gear 15 meshes with the gear 13, the gear 13 will rotate accordingly, which in turn drives the rightmost connecting pipe 12 to rotate. Because the connecting pipe 12 is fixedly connected to the four-jaw chuck 11, the rightmost four-jaw chuck 11 will drive the pipe it clamps to rotate. At the same time, the moving frames 8 on the left and right sides and the pipes will perform corresponding actions in sync to ensure that the pipes on both sides can rotate relative to each other during welding.

[0022] As the pipe begins to rotate, the welding torch 6 continues to weld the pipe in the appropriate position until the outer wall of the pipe is completely welded.

[0023] The linear slide 1 3, linear slide 2 4, and four-jaw chuck 11 in this utility model are existing technology devices, and their structures will not be described in detail. This utility model only protects the mechanical parts, and the functions implemented by the software control part are not within the scope of protection of this utility model.
