The invention discloses an ultrasonic automatic detection
system of
copper and stainless steel
dissimilar metal vacuum
brazing water connector, a hardware of which consists of a water connector automatic detection
system, a
single crystal immersion focusing probe and a
reference block; the detection device includes an industrial control
machine, a motor driver and motors which are controlled by the industrial control
machine and an ultrasonic flaw detection instrument which is respectively connected with the
single crystal immersion focusing probe and the industrial control
machine; the invention is characterized in that: one motor of the detection device drives a transmission shaft which is moved vertically, a probe angle adjuster is arranged on a shaft, the
single crystal immersion focusing probe is arranged at the lower end of a probe angle adjuster, the other motor drives a horizontal rotating disk which is provided with the water connector to be detected, the position of the probe in a water connector cavity body can be regulated by the regulation of the probe angle adjuster, and the ultrasonic
waves are transmitted for the detection of the
brazing quality of the water connector. The invention has the advantages that the probe structure is compact, the detection
system realizes the
automatic control, the detection sensitivity is high, the operation is simple, and the invention can automatically identify the defect, calculate the area of defect and provide the spreading picture of the detection results of the water connector rapidly, accurately and intuitively.
