A clamping assembly and a flexible jig 4 are provided on the upper side of the base plate 3. The flexible jig 4 drags the special-shaped metal parts, and the clamping assembly clamps from all sides to ensure that the special-shaped metal parts are clamped reliably. The clamping assembly includes a cam column 1 and an adjustment seat 2. The cam column 1 is made of rubber to effectively protect the surface of the parts. Copper or iron can be used as needed to improve the clamping reliability. The flexible jig 4 includes a fixed seat 41 and a top shaft 42, the top shaft 42 is provided with multiple groups and is evenly arranged on the fixed seat 41, the top of the top shaft 42 is in the shape of a spherical surface, the flexible fixture 4 is also called a universal fixture, which can reliably resist the surface of the part and provide support or clamping force, the top shaft 42 and the fixed seat 41 are slidably connected to facilitate fitting the complex surface of the part, the adjustment seat 2 and the fixed seat 41 are detachably connected to the bottom plate 3, which is convenient for adjusting the clamping and support position, and more stably clamping and fixing the parts, when the mass of the parts to be processed is large and the force generated by the processing is extremely large, different specifications of flexible fixtures 4 can be selected, and a thicker cam column 1 can be selected to stably clamp the parts;

[0029] In addition, an anti-skid groove 11 is provided on the protruding part of the cam column 1. There are multiple groups of anti-skid grooves 11, which are evenly arranged on the cam column 1 to ensure that the clamping between the cam columns 1 is more stable and reliable to avoid slipping. A frustum 12 is provided at the lower end of the cam column 1 for clamping parts with regular edges, such as flanges or end covers with flanges. The frustum 12 cooperates with the cam column 1 to clamp the parts. A rotating shaft 13 passes through the center of the base circle of the cam column 1. The cam column 1 and the rotating shaft 13 are fixedly connected. The rotation of the rotating shaft 13 is controlled to change the direction of the cam column 1, adapt to the complex surface structure of the parts, and stably clamp the parts.

[0030] Furthermore, the adjustment seat 2 includes a magnetic seat 21, a coarse adjustment screw 23 and a sliding seat 24. The sliding seat 24 is slidably connected to the magnetic seat 21.
