Description

Technical Field

[0001] This utility model relates to the field of automatic pipe welding machine technology, specifically an automatic pipe welding machine that facilitates pipe welding. Background Technology

[0002] An automatic pipe welding machine is a mechanical device that uses a welding torch to weld pipe joints, combining two pipes of different sizes to form a longer pipe. These operations usually require a pipe welding machine.

[0003] Early devices mostly used fixing mechanisms that could only fix corresponding sizes. If the pipe diameter was too long, it might not fit; if the diameter was too small, it might be unstable. Furthermore, they couldn't effectively support and fix pipes of different diameters, thus reducing the overall flexibility of the product. Additionally, during the welding process at the joints, the difficulty in flipping the two pipes after splicing to change the welding points resulted in poor welding quality and uniformity.

[0004] For example, the Chinese authorized patent CN 218556141 U (An Automatic Pipe Welding Machine for Facilitating Butt Welding) demonstrates that by adjusting the expansion and contraction of the rack, it can support pipe fittings of different diameters, offering excellent practicality. Rotating the lead screw moves the movable frame along its outer wall, allowing the two frames to move closer or further apart. This adjustment of the distance between the two frames, based on the required pipe fitting length, makes operation simple, convenient, and highly valuable. Starting the second motor drives a small transmission gear through its output shaft, which in turn rotates the pipe fitting held between the two large transmission gears, facilitating a one-time circumferential welding of the joint between the two pipe fittings, significantly improving work efficiency. This technical solution addresses the aforementioned problems.

[0005] However, the technical solution of this utility model still has some technical problems. When the automatic pipe welding machine welds long pipes, the two long pipes are too long, and the automatic pipe welding machine has certain requirements on the length range of the pipes to be placed and joined. As a result, the long pipes cannot be smoothly put into the automatic pipe welding machine, which makes the automatic pipe welding machine highly limited.

[0006] Therefore, an automatic pipe welding machine that facilitates butt welding of pipes is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide an automatic pipe welding machine that facilitates butt welding of pipes, in order to solve the problem mentioned in the background art that when welding long pipes, the two long pipes are too long and the automatic pipe welding machine has certain requirements on the length range for butt welding of the pipes, thus the long pipes cannot be smoothly put into the automatic pipe welding machine, resulting in the high limitation of the automatic pipe welding machine.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automatic pipe welding machine for easy butt welding of pipes, comprising a welding support:

[0009] A rotating clamping bracket is rotatably mounted on the outside of the welding bracket. The rotating clamping bracket has a boss inside and a limit rod inside. The limit rod is slidably connected to the welding bracket through a slot. A tensioning spring is installed on the outside of the end of the limit rod away from the rotating clamping bracket, and a clamping roller is fixedly installed on the end of the limit rod away from the rotating clamping bracket.

[0010] A storage platform is provided on both sides of the outside of the welding bracket. An extension rod is slidably installed inside the storage platform through a slot. A lifting bracket is fixedly installed at one end of the extension rod. An adjusting screw is installed inside the lifting bracket through a thread. A lifting plate is installed at the upper end of the adjusting screw.

[0011] Preferably, the outside of the rotary clamping bracket is fitted with a fixing screw, which is threadedly connected to the rotary clamping bracket.

[0012] Preferably, support legs are installed on both sides of the outside of the welding bracket, and the support legs are welded to the welding bracket.

[0013] Preferably, an mounting bracket is installed at the upper end of the welding bracket, and the mounting bracket is fixedly connected to the welding bracket.

[0014] Preferably, an automatic welding gun is mounted on the upper end of the mounting bracket.

[0015] Preferably, the lifting plate is rotatably connected to the adjusting screw, and the clamping spring is fixedly connected to the clamping roller and the welding bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model allows the lifting bracket to move when welding long pipes by installing an extension rod, thereby enabling the lifting bracket to work with the lifting plate to lift the pipes and ensure that they can be placed horizontally, preventing the pipes from tilting. This allows the device to weld pipes of different lengths, and allows pipes of various lengths to be placed inside the device, enhancing the device's practicality. At the same time, when welding shorter pipes, the extension rod can be retracted into the storage platform, reducing the device's footprint.

[0018] 2. This utility model, by installing a limiting rod, can work in conjunction with a rotating clamping bracket with an internal boss and a tightening spring. When the rotating clamping bracket rotates, the limiting rod can push the clamping roller to simultaneously clamp pipes of different diameters, so that the pipes are clamped on the center line of the welding bracket. This makes it easier for workers to quickly position and align the two pipes, thus improving the welding efficiency of the pipes. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-4 One embodiment of this utility model is an automatic pipe welding machine that facilitates butt welding of pipes, including a welding support 1.

[0026] A rotating clamping bracket 2 is rotatably mounted on the outside of the welding bracket 1. The rotating clamping bracket 2 has a boss inside and a limit rod 12 inside. The limit rod 12, in conjunction with the rotating clamping bracket 2 with the boss inside and the clamping spring 13, allows the rotating clamping bracket 2 to rotate. The limit rod 12 can push the clamping roller 14 to clamp pipes of different diameters synchronously, so that the pipes are clamped on the center line of the welding bracket 1. This facilitates the workers to quickly position and align the two pipes, improving the welding efficiency of the pipes. The limit rod 12 is slidably connected to the welding bracket 1 through a slot. The clamping spring 13 is installed on the outside of the end of the limit rod 12 away from the rotating clamping bracket 2, and the clamping roller 14 is fixedly installed on the end of the limit rod 12 away from the rotating clamping bracket 2.

[0027] The storage platform 6 is located on both sides outside the welding bracket 1. An extension rod 7 is slidably installed inside the storage platform 6 through a slot. When welding long pipes, the extension rod 7 can move the lifting bracket 8, thereby allowing the lifting bracket 8 to work with the lifting plate 9 to lift the pipe to ensure that it can be placed horizontally and prevent it from tilting. This allows the device to weld pipes of different lengths, and all pipes of various lengths can be placed inside the device, enhancing its practicality. At the same time, when welding shorter pipes, the extension rod 7 can be retracted into the storage platform 6, reducing the footprint of the device. One end of the extension rod 7 is fixedly installed with the lifting bracket 8. An adjusting screw 10 is threadedly installed inside the lifting bracket 8, and the upper end of the adjusting screw 10 is installed with the lifting plate 9.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The rotating clamping bracket 2 is externally fitted with a fixing screw 3, which is threadedly connected to the rotating clamping bracket 2. Support legs 11 are installed on both sides of the welding bracket 1, and the support legs 11 are welded to the welding bracket 1. An installation bracket 4 is installed at the upper end of the welding bracket 1, and the installation bracket 4 is fixedly connected to the welding bracket 1. An automatic welding gun 5 is installed at the upper end of the installation bracket 4, which facilitates the welding of pipe fittings by the workers and ensures the integrity of the device's functionality. The lifting plate 9 is rotatably connected to the adjusting screw 10. The clamping spring 13 is fixedly connected to the clamping roller 14 and the welding bracket 1.

[0029] Working Principle: During use, the operator inserts two pipe fittings into the device from both ends of the welding bracket 1. The operator then adjusts the position of the two pipe fittings so that the joint is directly below the automatic welding torch 5. Next, the operator rotates the rotating clamping bracket 2, causing the boss inside the bracket 2 to push the limiting rod 12, which in turn clamps the pipe fitting with the clamping roller 14 at one end of the limiting rod 12. The operator then tightens the fixing screw 3 to fix the position of the rotating clamping bracket. Next, the operator pulls the lifting bracket 8 to extend the extension rod 7, thus lengthening the device. Then, the operator tightens the adjusting screw 10 to move the lifting plate 9 upwards, lifting the pipe fitting to ensure it is placed horizontally. Finally, the operator uses the automatic welding torch 5 to weld the pipe fitting. During welding, the operator only needs to use their hands... The device can be used to rotate pipe fittings. A limiting rod 12, in conjunction with a rotating clamping bracket 2 with an internal boss and a tightening spring 13, allows the rotating clamping bracket 2 to rotate. The limiting rod 12 then pushes the clamping rollers 14 to simultaneously clamp pipe fittings of different diameters, ensuring the fittings are clamped on the center line of the welding bracket 1. This facilitates quick positioning and alignment of two pipe fittings, improving welding efficiency. The extension rod 7 allows the lifting bracket 8 to move when welding long pipe fittings, enabling it to work with the lifting plate 9 to lift the pipe fitting horizontally, preventing tilting. This allows the device to weld pipe fittings of different lengths, enhancing its practicality. Furthermore, when welding shorter pipe fittings, the extension rod 7 can retract into the storage platform 6, reducing the device's footprint.
