The working principle of the carburetor automatic detection machine of the present invention is as follows: the carburetor is installed on the carburetor positioning tool, and the oil squeeze cup device squeezes the oil cup to realize the replacement of the oil in the carburetor oil cup with the oil supply The consistency in the system, the oil supply system supplies oil to the carburetor; the swivel frame device pulls the swivel frame to the fully open position of the choke valve (plunger) to prepare for the detection of full-open negative pressure and full-open flow, And check the oil flow at this time to achieve full-open flow detection, and when the full-open flow does not meet the requirements, the full-open flow adjustment device rotates the full-open flow adjustment screw on the carburetor to achieve full-open flow adjustment; negative pressure The system sucks air into the carburetor, and detects the negative pressure value at this time to achieve full-open negative pressure detection; pull the suspension device to reset the carburetor upper swing frame, and do a good job for the detection of idle negative pressure and idle flow. Prepare, the oil supply system supplies oil to the carburetor, and detects the oil flow at this time to achieve idle flow detection, and when the idle flow does not meet the requirements, turn the main meter needle device to turn the main meter on the carburetor The hole achieves idle flow adjustment; the negative pressure system sucks air into the carburetor and detects the negative pressure value at this time to achieve idle negative pressure detection, and when the idle negative pressure does not meet the requirements, the idle screw device spins The idle speed screw on the oil tank can adjust the idle speed negative pressure. Each test data is tested, calibrated and debugged based on the stored data in the system as a benchmark.
