Abstract

This invention discloses a fixed-length tool loading device for a CNC milling machine, comprising a support column and a conical head. The conical head is fixedly connected to the left side of the support column, and a first collar is fixedly sleeved on the left side of the outer wall of the support column. The first collar has first grooves at both its upper and lower ends. A second collar is fixedly sleeved on the middle of the outer wall of the support column, and a first sleeve is threadedly connected to the right side of the outer wall of the support column. This fixed-length tool loading device for a CNC milling machine, through the cooperation of the second sleeve and the first groove, allows the operator to easily control the tool insertion depth by controlling the extension length of the second sleeve, thereby controlling the tool extension to a certain length. This facilitates operation. Through the cooperation of a compression spring and a second washer, the tool is automatically held in place by the pressure of the compression spring after the jaws are released, facilitating easy and convenient tool replacement and meeting customer needs.
