Abstract
The utility model relates to an installation base structure for collet and chuck free switching of a row knife numerical control machine tool. A cylinder shaft hole and a circular cone shaft hole are formed in an installation base body in the axial direction, a big opening of the circular cone shaft hole faces toward the right side, the circular cone shaft hole is coaxially connected to the right end of the cylinder axis hole, and a main shaft front end disc positioning ring is coaxially connected to the left end face of the installation base body in an integrated mode, and the diameter of the inner circle of the main shaft front end disc positioning ring is larger than that of the cylinder shaft hole. The diameter of the outer circle of the main shaft front end positioning ring is larger than that of the outer circle of the installation base body. Stepped holes are formed in the installation base body and penetrate through the main shaft front end disc positioning ring, and chuck installation screw holes are formed in the installation base body and are blind holes. The installation base structure not only can be used for installing a collet, but also can be used for installing a chuck, resource loss of raw materials is reduced, the collet or the chuck is convenient to freely install on a machine tool main shaft component, installation time is shortened, working efficiency is improved, and the machining capacity of the machine tool is improved.
