おける工具交換装置。 The tool supported on the spindle and the tool from the tool magazine can be exchanged simultaneously by the back-and-forth stroke movement and rotational movement of the exchange arm between the spindle and the tool magazine using the arm axis parallel to these axes. In the device, a camshaft is provided in a direction perpendicular to the arm axis, and the camshaft includes a first cam element for causing clockwise and counterclockwise rotational movement of the exchange arm; A second cam element for causing a back and forth stroke movement of the exchange arm and a third cam element for operating a tool clamping cylinder on the main shaft.
A cam member integrally having a cam element is attached,
Between this cam member and the arm shaft, the first
a first engaging member that is operated by engaging with the cam element to transmit rotational motion to the arm shaft; and a first engaging member that is operated by engaging with the second cam element to transmit forward and backward motion to the arm shaft. A second engaging member is provided, and a pressure increasing cylinder is connected to the tool clamping cylinder, and the pressure increasing cylinder is engaged with the third cam element between the piston rod of the pressure increasing cylinder and the cam member to operate. A tool for a machine tool, characterized in that a third engagement member is provided for moving the piston rod forward and backward, and rotation of the cam member by a motor causes the tool exchange operation of the exchange arm and the tool clamp/unclamp operation of the main shaft to be performed. Exchange device.
