Abstract
A processing machine includes a splash guard, a tool spindle that is provided inside a processing area and holds a tool, and an automatic tool changer that is movable between an internal-side tool changing position inside the processing area and a standby position outside the processing area and changes the tool held by the tool spindle at the internal-side tool changing position. The splash guard includes a cover body that is coupled to the automatic tool changer, defines and forms the processing area when the automatic tool changer is positioned at the standby position, and enters the processing area when the automatic tool changer moves from the standby position to the internal-side tool changing position.
Claims4
A processing machine comprising:
- a splash guard;
- a processing area in which a workpiece is processed;
- a tool holder that is provided in the processing area and that holds a first tool for processing the workpiece;
- a tool magazine that is provided outside of the processing area and that stores a plurality of tools;
- a first coupling mechanism;
- and
- an automatic tool changer that is movable in a linear direction between a first tool changing position located inside the processing area and a standby position located outside of the processing area and that changes the first tool held by the tool holder at the first tool changing position, the splash guard separating the processing area and an area where the standby position is,
- wherein the splash guard includes a cover body that is connected to the automatic tool changer and that is movable in the linear direction integrally with the automatic tool changer, the cover body separating the processing area from the area where the automatic tool changer is positioned at the standby position, and the cover body entering the processing area when the automatic tool changer moves from the standby position to the first tool changing position,
- wherein the automatic tool changer is further movable between the standby position and a second tool changing position located outside of the processing area, the automatic tool changer automatically changing the first tool between the tool magazine and the automatic tool changer at the second tool changing position,
- wherein the first coupling mechanism is operable between a first state in which the automatic tool changer and the cover body are coupled by the first coupling mechanism when the automatic tool changer is positioned at the standby position and a second state in which the automatic tool changer and the cover body are uncoupled when the automatic tool changer moves from the standby position to the second tool changing position.
