Abstract

This utility model discloses a multi-size adaptable machine tool chuck, belonging to the field of machine tool processing technology. It includes a chuck with four grooves at its four equal division points on its upper surface, each groove facing one of the four directions. Four linkage screws are rotatably connected to each of the four grooves, and sliders are threaded onto the outer walls of the linkage screws. This multi-size adaptable machine tool chuck, through the configuration of linkage screws, sliders, and chucks, allows the sliders on their outer walls to move under the action of the threads during workpiece processing. The four sliders drive the four chucks to adjust the clamping distance according to the size of the workpiece, moving them closer or further apart. Furthermore, it can automatically adjust the clamping contact surface based on the workpiece size. In this way, it can automatically adapt to the clamping requirements of different workpiece sizes without changing components, improving workpiece processing efficiency and reducing processing costs.
