REMOTE CONTROLLED FREELY PIVOTAL NOZZLE

摘要

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.
