[0002] In the field of metal valve accessory machining, the clamping devices of traditional machining equipment are mostly fixed structures, which can only adapt to standard circular or regular-shaped accessories. When facing arc-shaped valve accessories with different radii, there is generally a poor adaptability problem, and it is impossible to achieve close fitting and fixing, which leads to displacement of the accessories during cutting, directly affecting the machining precision and quality. At the same time, the driving mechanism of the traditional cutting device mostly adopts a linear moving design, and its cutting trajectory is fixed as a straight line, which cannot be dynamically adjusted according to the curved surface profile of the arc-shaped accessory. When cutting the arc-shaped groove or modifying the surface of the arc-shaped shell, the straight cutting trajectory cannot match the arc-shaped surface of the accessory, and the surface flatness is poor, which not only reduces the machining precision of the arc-shaped structure, but also leads to poor surface quality of the finished product.
