An automatic tool exchanger provided in a multi-functional processing machine, the multi-functional processing machine includes a tool main spindle device disposed at a center between a first spindle device and a second spindle device, the automatic tool exchanger comprising:
- a tool magazine that is disposed positioned at a front surface upper portion of a machine body of the multi-functional processing machine and is configured to house at least one tool for exchange with the tool main spindle device;
- a shift device configured to move the at least one tool between the tool magazine and a tool exchanging position;
- and
- a tool changer configured to exchange the at least one tool between the shift device and the tool main spindle device,
- wherein the tool changer is provided with a tool exchange arm fixed to an output shaft, the output shaft rotates and moves up and down,
- wherein the tool exchange arm has a pair of chucks, each of the chucks includes a respective fixed claw and a respective movable claw, wherein the chucks are configured to be symmetrical about a rotation axis, and wherein each of the movable claws is maintained in a constant open state by biasing force of a respective chuck spring, and
- wherein a respective gripping state of each of the movable claws, generated by pivoting the movable claws against the at least one tool, is maintained by a respective lock mechanism.
