Description

Technical Field

[0001] This application relates to the field of welding processing. Specifically, it relates to a fixed fixture for welding annular cylinders. Background Art

[0002] The fixed fixture for welding annular cylinders is a tooling device used to fix and support annular workpieces (such as pipes, cylinders, etc.) for welding or other processing operations. Such fixed fixtures are very common in industrial manufacturing, mainly used to ensure the stability and precise position of the annular workpiece during the welding process, thus ensuring the welding quality and efficiency.

[0003] The patent document with the publication number CN216466300U discloses an energy-saving PE pipe welding fixture for water conservancy projects, which relates to the technical field of an energy-saving PE pipe welding fixture for water conservancy projects. This energy-saving PE pipe welding fixture for water conservancy projects includes a first annular shell and a second annular shell. The right side of the first annular shell is hinged to the second annular shell. A support seat is fixedly connected to the bottom of the second annular shell. An arc-shaped airbag is fixedly connected to the inner wall of the first annular shell. The left end of the arc-shaped airbag is communicated with an air pipe. One end of a torsion spring is fixedly connected to the inner wall of the air pipe. Although the arc-shaped airbag is inflated during use in the above application document to make the arc-shaped airbag expand and tightly fit the pipe, clamping the PE pipe while avoiding scratching the PE pipe, when it comes to the work that requires a long-term clamping force, manual pressing of the pressing block may increase the labor intensity and fatigue degree of the operator. Especially in large-scale production, this manual control may not be persistent or efficient enough. Summary of the Utility Model
