[0002] The utility model with authorization announcement number: CN214489663U discloses a special clamp for CNC lathes in the technical field of CNC lathes, including a slide rail and a slider that slides and is fixed on the slide rail. A clamp seat is installed on the slider, and a screw rod is connected to the clamp seat through a motor drive. The motor controls its forward and reverse rotation through a second switch. The screw axis is perpendicular to the moving direction of the slider. The left part of the screw is left-handedly screwed with a left-handed slide seat, and the right part of the screw is right-handedly screwed with a right-handed slide seat. Mounting seats with a V-shaped structure are symmetrically arranged on the top of the left-handed slide seat and the right-handed slide seat. The side walls of the two groups of mounting seats with a V-shaped structure are movably connected with rollers. The utility model supports a rotating body with a longer length through the rollers on the two groups of mounting seats with a V-shaped structure that are symmetrical to each other, so as to avoid bending when the length is long. The two groups of mounting seats are close to or away from each other at the same time, which is conducive to clamping rotating bodies with different outer diameters, and the movable rollers are prevented from being scratched by the rotating bodies.
