Abstract
A liquid spraying apparatus for use in a machining tool or the like for spraying liquid, such as lubricant or washing water, over a desired location is provided. The apparatus generally includes a nozzle assembly and an orientation control unit operatively coupled to the nozzle assembly for controlling the orientation of its nozzle. The nozzle assembly includes a nozzle pipe which is pivotally supported. An L-shaped arm is operatively coupled to the nozzle pipe and also fixedly attached to a transmission member which is operatively coupled to a pair of motors. The transmission member is caused to move linearly back and forth by one of the motors and also caused to rotate back and forth by the other motor, so that the nozzle pipe may be oriented in a desired direction by the operation of the two motors.
Claims5
A liquid spraying apparatus for use in a machining tool comprising:
- an elongated nozzle pipe;
- supporting means for supporting one end of said pipe pivotally on a frame such that said pipe may pivot around a predetermined pivotal point defined by said supporting means;
- moving means operatively coupled to said pipe for moving said pipe pivotally around said predetermined pivotal point within predetermined limits;
- first driving means fixedly mounted on said frame and operatively coupled to said moving means for driving to move said moving means in a first direction back and forth;
- second driving means fixedly mounted on said frame and operatively coupled to said moving means for driving to move said moving means in a second direction different from said first direction back and forth;
- and
- wherein said moving means includes an arm operatively coupled to said pipe and an elongated and hollow transmission member to which said arm is also fixedly attached, said transmission member being operatively coupled to said first and second driving means.
