Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, specifically to an auxiliary tool for pipe cutting. Background Technology

[0002] Pipeline installation, maintenance, and renovation projects often require pipe cutting. Currently, engineers commonly use abrasive wheel cutting machines for this purpose. Abrasive wheel cutting machines offer advantages such as high cutting speed and precision.

[0003] In the existing technology, when abrasive wheel cutting machines cut pipes, they usually use manual fixing or simple clamps for fixing. These methods are prone to loosening during the cutting process, especially for round pipes, which are not easy to fix, resulting in a decrease in cutting quality. Due to the unstable fixing of the pipe, deviations are prone to occur during the cutting process, resulting in inaccurate cutting dimensions.

[0004] Therefore, an auxiliary tool for pipe cutting is needed to improve the above problems. Utility Model Content

[0030] The base plate 1 connects with the base of the abrasive wheel cutter through the clamping groove 2 at its lower end. The support structure supports the pipe 9, which is divided into a middle support 8 and a side support 6, which support the two ends and the middle of the pipe 9 respectively. At the same time, the fixing belt assembly at both ends passes through the side support 6 to limit and fix the two ends of the pipe 9, ensuring the stability of the pipe 9 during the cutting process.

[0031] Please refer to Figure 1 , 2 3, 4, 5 and 6, the clamping assembly includes a set of adjusting rods a4 that pass through the end of the base plate 1.
