Washing nozzle for machine tool and machine tool therein

A washing nozzle arranged on an upper surface or a side surface inside a machine tool, the washing nozzle configured to wash an inside of the machine tool with fluid, the machine tool having a supply port for the fluid in the upper surface or the side surface inside the machine tool,

• the washing nozzle comprising:
• a base portion having a tubular passage inside thereof, the base portion mounted to at least one of the upper surface or the side surface inside the machine tool, and communicates to the supply port through the tubular passage, the base portion arranged so as to extend perpendicular to the surface on which the base portion is mounted, the base portion rotatable about an axis perpendicular to a surface on which the base portion is mounted, the base portion having a nozzle jet port and a nozzle flow passage allowing communication between the tubular passage and the nozzle jet port;
• and
• a body portion rotatable about an axis of the base portion with respect to the base portion, the body portion including a jet port configured to jet fluid so as to cause the body portion to rotate about an axis of the base portion.

A washing nozzle arranged on a surface of a workpiece table in a machine tool, the washing nozzle configured to wash an inside of the machine tool with fluid, the machine tool having a supply port for the fluid in the surface of the workpiece table inside the machine tool,

• the washing nozzle comprising:
• a base portion having inside thereof a tubular passage, the base portion mounted to the workpiece table inside the machine tool;
• and
• a first rotary member rotatable in one direction about an axis parallel to a surface on which the base portion is mounted, and has inside thereof a nozzle jet port and a nozzle flow passage allowing communication between the tubular passage and the nozzle jet port.

A machine tool comprising a first washing nozzle and a second washing nozzle which are arranged on an upper surface or a side surface inside the machine tool,

• the first washing nozzle including:
• one base portion having inside thereof a tubular passage, the one base portion mounted to at least one of the upper surface or the side surface inside the machine tool, wherein the one base portion communicates to the supply port through the tubular passage;
• and
• a rotary member rotatable about an axis parallel to a surface on which the one base portion is mounted, and has inside thereof a nozzle jet port and a nozzle flow passage allowing communication between the tubular passage and the nozzle jet port, the jet port configured to allow fluid jetted from the jet port of the rotary member to hit the surface on which the one base portion is mounted and cause the jet of the fluid to be jetted so as to cause the rotary member to rotate about the parallel axis,
• the second washing nozzle including:
• another base portion having inside thereof a tubular passage, the another base portion mounted to the workpiece table inside the machine tool;
• a nozzle jet port rotatable in one direction about an axis parallel to the surface on which the another base portion is mounted;
• and
• a first rotary member having inside thereof the tubular passage and a nozzle flow passage allowing communication with the nozzle jet port.
