Abstract
The invention discloses a clamping method of a spool welding side. When the acting force on the inner walls of pipes from a swing arm becomes the largest, a cutting knife on a lathe begins machining the edges of the pipes in a rotating mode, and the swing arm capable of being freely adjusted can be used for beveling of the pipes of different diameters. An upper swing rod, a lower swing rod, a lower pulling rod and a fixing rod form a triangular frame. According to the principle that the stability of a triangle is the best, the swing arm can provide stable clamping force for the inner walls of the pipes, and the beveling efficiency of the pipes can be guaranteed.
