Automobile oil nozzle cleaning detector

The invention discloses a washing and detecting instrument for an automobile oil spray nozzle, and relates to a detecting device of the automobile oil spray nozzle free of ultrasonic cleaning, which aims to solve the problems of the existing devices that the washing and detecting of the automobile oil spray nozzle cannot be operated on the same machine and that the cost is high. A plurality of measuring cylinders are positioned on the upside of an auxiliary oil tank; the bottoms of a plurality of measuring cylinders mutually communicate with each other; both ends of an oil valve respectively communicate with a plurality of measuring cylinders and the auxiliary oil tank; the auxiliary oil tank is positioned on the upside of a main oil tank; both ends of the connecting pipe of the oil tank respectively communicate with the auxiliary oil tank and the main oil tank, a suction side of an oil pump communicates with the main oil tank; the discharge side of the oil pump communicates with an oil distributor; one output end of a controller is connected with the power end of the oil pump; the other output end of the controller is connected with the input end of a square wave generator; the square wave generator outputs the square wave of 10Hz to 120Hz when cleaning and detection are carried out. The cleaning and detection of the automobile oil spray nozzle can be completed by one instrument. Therefore, the operation is simple and the cost is low.
