The utility model discloses a novel tool setting structure for a numerically-controlled
machine tool, which relates to the technical field of numerically-controlled
machine tools and comprises a
workbench, a mounting plate rotatably mounted on one side of the
workbench, a tool setting gauge mounted on the mounting plate through bolts, a worm gear fixedly mounted on a rotating shaft of the mounting plate, a worm rotatably mounted on one side of the
workbench, and a worm mounted on the other side of the workbench. A worm is installed on the workbench and meshed with the worm gear, a second motor is fixedly installed on the side, provided with the installation plate, of the workbench, the output end of the second motor is fixedly connected with one end of the worm, a fixing plate is fixedly installed on the side, provided with the installation plate, of the workbench, and a rotating plate is rotationally installed on the fixing plate. The second motor is used for driving the worm to rotate, the worm drives the worm gear to rotate, the worm gear drives the mounting plate and the tool setting gauge to rotate by 90 degrees, and therefore the tool setting gauge is hidden and stored on one side of the workbench, the space of the workbench cannot be occupied, and a tool cannot be cracked up.
