Support rails are arranged along the length of the base frame. Several support devices are slidably mounted on the support rails to support horizontally placed pipe workpieces, allowing the pipe workpieces to rotate freely on the support devices. The lifting chuck device is mounted on the base frame and located at one end of the support rails, used to clamp the end of the pipe workpiece and drive it to rotate at a set angle. The clamping height of the lifting chuck device is adjustable. The welding device includes a movable platform slidably mounted on the support rails, on which a welding operation assembly is mounted. The welding operation assembly is used to extend into the pipe workpiece and weld its inner wall. This pipe welding device is suitable for pipe workpieces of various sizes, reducing welding difficulty, improving welding efficiency, and ensuring welding quality. However, the device has certain shortcomings in use: it is not convenient to adjust the relative angle between two pipes, making it difficult to weld two pipes at different angles; also, it is not convenient to clamp and fix pipes of different diameters. Therefore, improvements are needed. Utility Model Content

The support drives the connecting rod to rotate relative to the support shaft, causing the angle between the two support rings to change, thereby changing the included angle between the pipes within the two support rings, allowing adjustment of the welding angle. Simultaneously, by rotating the threaded ring and the sliding column to perform threaded movement, the limit pin is pressed against the base plate, facilitating limit positioning after support adjustment.

[0006] Preferably, a slider is fixedly connected to the lower end of the support, and the slider is slidably connected to the base plate. The support is supported by the slider.

By rotating the double-ended screw and the connecting plate to perform threaded movement, the connecting plate drives the square rod to move, thereby causing the clamping plate to move and contact the pipe, thus enabling clamping and limiting of pipes of different diameters.

[0010] Preferably, a limiting plate is fixedly connected to the upper end of the support ring, and the limiting plate is slidably connected to the bidirectional screw. By setting the limiting plate, the bidirectional screw is prevented from moving out of control.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

This utility model uses a support to drive a connecting rod to rotate relative to the support shaft, which causes the angle between the two support rings to change, and in turn, the included angle between the pipes inside the two support rings to change, thus adjusting the welding angle. At the same time, by rotating the screw ring and the sliding column to make threaded movement, the limiting pin is pressed against the base plate, making it easy to limit the position after the support is adjusted.

[0013] 2. This utility model uses the rotation of a bidirectional screw and a connecting plate to make a threaded motion, which in turn causes the connecting plate to move the square rod, thereby causing the clamping plate to move and contact the pipe, thus enabling clamping and limiting of pipes of different diameters.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 A pipe welding device includes a base plate 1, a support shaft 2 fixedly connected to the upper end of the base plate 1, an adjustment mechanism 3 provided on the support shaft 2, a sliding plate 4 provided on the adjustment mechanism 3, a support ring 5 fixedly connected to the upper end of the sliding plate 4, a clamping mechanism 6 provided on the support ring 5, and a welding machine 7 provided on the base plate 1.

[0021] Please see Figures 1-3 The adjusting mechanism 3 includes a connecting rod 31. The connecting rod 31 is slidably connected inside the support shaft 2, and a screw pin 32 is movably connected inside the support shaft 2. The screw pin 32 and the connecting rod 31 are connected by threads. A support 33 is fixedly connected to the end of the connecting rod 31. A slider 34 is fixedly connected to the lower end of the support 33. The slider 34 is slidably connected to the base plate 1. The slider 34 supports the support 33. A sliding column 35 is fixedly connected to the lower end of the support 33. The sliding column 35 is slidably connected to the base plate 1. A support plate 36 is fixedly connected to the outer side of the sliding column 35. The support plate 36 is slidably connected to the base plate 1. A threaded ring 37 is threadedly connected to the outer side of the sliding column 35. A limit pin 38 is slidably connected inside the support plate 36. One end of the limit pin 38 contacts the threaded ring 37, and the limit pin 38 contacts the base plate 1. The limit pin 38 facilitates adjustment of the support 33 after adjustment. The support 33 and the slide plate 4 are slidably connected. Inside the support 33, a lead screw 39 is installed via a bearing. The lead screw 39 and the slide plate 4 are movably connected. The outside of the lead screw 39 is connected to a pressure plate 310 via a thread. The pressure plate 310 and the support 33 are slidably connected. A spring 311 is provided on the outside of the lead screw 39. One end of the spring 311 is fixedly connected to the pressure plate 310, and the other end of the spring 311 is fixedly connected to the slide plate 4. By setting the spring 311, the slide plate 4 is elastically compressed. The support 33 drives the connecting rod 31 to rotate relative to the support shaft 2, causing the angle between the two support rings 5 ​​to change, and thus the included angle between the pipes inside the two support rings 5 ​​to change. This can adjust the welding angle. At the same time, by rotating the screw ring 37 and the sliding column 35 to make threaded movement, the limiting pin 38 is pressed onto the base plate 1, so that the support 33 can be easily limited after adjustment.

[0022] Please see Figures 1-4 The clamping mechanism 6 includes a square rod 61, which is slidably connected inside the support ring 5. One end of the square rod 61 is fixedly connected to a connecting plate 62, and a bidirectional screw 63 is threadedly connected inside the connecting plate 62. A limit plate 64 is fixedly connected to the upper end of the support ring 5, and the limit plate 64 and the bidirectional screw 63 are slidably connected. By setting the limit plate 64, the bidirectional screw 63 is prevented from moving. The other end of the square rod 61 is fixedly connected to a clamping plate 65. By rotating the bidirectional screw 63 and the connecting plate 62 to make threaded movements, the connecting plate 62 drives the square rod 61 to move, thereby causing the clamping plate 65 to move and contact the pipe. This allows for clamping and limiting pipes of different diameters.

[0023] The specific implementation process of this utility model is as follows: In use, the pipe is passed through the support ring 5, and the double-ended screw 63 is manually rotated. The rotation of the double-ended screw 63 and the connecting plate 62 make threaded movements, which in turn causes the connecting plate 62 to drive the square rod 61 to move, thereby causing the clamping plate 65 to move and contact the pipe. This allows for clamping and limiting of pipes of different diameters. Then, according to the pipe angle adjustment device, the support 33 is manually moved to drive the connecting rod 31 to rotate relative to the support shaft 2, causing the angle between the two support rings 5 ​​to change, which in turn causes the included angle between the pipes within the two support rings 5 ​​to change. The welding angle can be adjusted. At the same time, by rotating the screw ring 37 and the sliding column 35 to make threaded movement, the limiting pin 38 is pressed onto the base plate 1, so that the support 33 can be easily limited after adjustment. Then, the lead screw 39 is rotated, and the lead screw 39 rotates and the pressure plate 310 makes threaded movement, so that the pressure plate 310 elastically squeezes the spring 311, so that the slide plate 4 drives the support ring 5 to move, so that the support ring 5 moves through the clamping mechanism 6, and thus the pipe moves, so that the two pipes are elastically squeezed together, avoiding gaps between the two pipes during the welding process.
