Specifically, special-shaped parts refer to structural parts whose dimensions, shapes or structures are different from those of standard parts or commonly used parts. Among them, the most common are special-shaped tubes. In the production and processing of special-shaped tubes, it is often necessary to use clamping tools to limit the position of the special-shaped tubes so that they can be polished, drilled, sprayed, etc.

[0044] S5, when it is necessary to convert different faces of the octagonal special-shaped tube 5, a certain workpiece frame 303 is driven to rotate by the servo motor 6, thereby driving the clamping mechanism 4 and the entire octagonal special-shaped tube 5 to rotate, so as to realize the adjustment conversion of different faces of the octagonal special-shaped tube 5;
