Abstract

An automatic tool changer includes a cover that partitions a machining area and a non-machining area, and an opening/closing member that opens/closes an opening of the cover by turning in synchronization with rotation of a tool changer magazine. The opening/closing member includes a plate section partitions the machining area and the non-machining area at a position of the opening of the cover. In a case where the tool changer magazine performs tool replacement with respect to a tool storage magazine, the plate section closes the opening of the cover by taking a horizontal posture. In a case where the tool changer magazine performs tool replacement with respect to a main spindle, the plate section opens the opening of the cover by changing its posture from the horizontal posture to an inclined posture or a vertical posture.

Dependent claims

An automatic tool changer comprising:

a tool storage magazine that stores a tool to be attached to a main spindle of a machine tool;
a tool changer magazine that rotates, the tool changer magazine performing tool replacement with respect to the main spindle and with respect to the tool storage magazine;
a cover that partitions a machining area where the tool changer magazine performs tool replacement with respect to the main spindle, and a non-machining area where the tool changer magazine performs tool replacement with respect to the tool storage magazine;
an opening, disposed in the cover, that enables transfer of a tool between the tool changer magazine and the main spindle;
and
an opening/closing member that opens/closes the opening by turning in synchronization with rotation of the tool changer magazine, wherein
the opening/closing member comprises a plate section that partitions the machining area and the non-machining area at a position of the opening,
the plate section closes the opening by taking a horizontal posture or a vertical posture, in a case where the tool changer magazine performs tool replacement with respect to the tool storage magazine, and
the plate section opens the opening by changing a posture from the horizontal posture to an inclined posture or the vertical posture, or from the vertical posture to the inclined posture or the horizontal posture, in a case where the tool changer magazine performs tool replacement with respect to the main spindle.
