This invention belongs to the field of machine tool processing technology, specifically a CNC machine tool workpiece clamping mechanism, including a main clamping shell and a pressure-applying component. The pressure-applying component clamps and secures a cylindrical part inserted into the axis of the main clamping shell. The pressure-applying component has an arc-shaped pressure plate, with a pressure sensor fixedly connected to the top of the inner cavity of the arc-shaped pressure plate, and a lower pressure inner shell slidably connected to the bottom of the inner cavity of the arc-shaped pressure plate via a thick spring band. During the turning process of cylindrical parts, if the clamping jaws are used directly to clamp and secure the cylindrical part, the outer wall of the shell will be concave, resulting in clamping marks. In severe cases, excessive deformation can lead to part scrap. Conversely, loose clamping jaws can prevent the cylindrical part from being clamped securely. Therefore, this device uses an inner support component inserted inside the part to cooperate with the external pressure-applying component, thereby ensuring that both the inner and outer sides of the cylindrical part are subjected to clamping force, preventing deformation of the cylindrical part due to external forces.
