Technical Field

[0001] This utility model relates to a pipe welding machine, specifically a vertical pipe welding machine. Background Technology

[0002] Pipe welding machines are generally set up horizontally, rotating the pipes to achieve circumferential welds. However, when two pipes rotate, they are prone to displacement, resulting in poor concentricity and affecting the welding effect. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a vertical pipe welding machine. This utility model arranges the pipe vertically, eliminating the need to rotate the pipe while allowing the welding machine to rotate, which facilitates welding, reduces the error rate, and improves the welding effect.

[0004] To achieve the above technical objectives, this utility model adopts the following technical solution: a vertical pipe welding machine, comprising,

[0005] At least three pillars, each pillar having a long groove;

[0006] Two pipe connectors are provided, each with a pipe sliding block located in the long groove. Each connector is also provided with a pipe fastening bolt, which passes through the long groove and is fastened. Each connector is also provided with at least three fixing rods, the ends of which can fasten the pipe.

[0007] The welding machine connector includes a welding machine sliding block located within the elongated groove, a welding machine fastening bolt inserted into and fastened within the groove, and an annular rack capable of circular motion. The annular rack is fixedly connected to the welding machine and engages with a gear.

[0008] The pipe connector includes a pipe annular plate, and three pipe sliding blocks are fixedly disposed on the outer wall of the pipe annular plate.

[0009] The inner wall of the pipe annular plate is provided with a fastening gasket, and a threaded block is fixed on the inner wall of the fastening gasket. The pipe fastening bolt passes through the pipe annular plate and the fastening gasket and is then threaded to the threaded block. The pipe fastening bolt is also fitted with a pad.

[0010] The fixing rod is threaded to the pipe annular plate and a clamping plate is fixed at its inner end. The clamping plate has an arc-shaped structure.

[0011] The welding machine connector includes a welding machine annular plate, and three welding machine sliding blocks are fixedly disposed on the outer wall of the welding machine annular plate.

[0012] The outer edge of the annular plate of the welding machine is also fixed with three protrusions. The protrusions are located inside the long groove. The protrusions are threadedly connected to the fastening bolts of the welding machine. The fastening bolts of the welding machine are fitted with washers.

[0013] The inner wall of the welding machine's annular plate is provided with an annular track, the annular rack is located inside the annular track, the upper and lower walls of the annular track are provided with a first annular groove, the upper and lower walls of the annular rack are provided with a second annular groove, and the annular cavity formed by the first annular groove and the second annular groove is filled with a steel ball.

[0014] The outer wall of the annular plate of the welding machine has a through hole, and the gear meshes with the annular rack in the through hole.

[0015] In summary, this utility model achieves the following technical effects:

[0016] This invention utilizes two pipe connectors to fix the two pipes together, ensuring good stability. The welding machine connector, in conjunction with its own ring rack, allows the welding machine to rotate, replacing the pipe rotation method, resulting in better welding performance.
