Railway cantilever assembly surface automatic flaw detection equipment and flaw detection method

The invention belongs to the technical field of railway cantilever production, and particularly relates to railway cantilever assembly surface automatic flaw detection equipment and a flaw detection method.The railway cantilever assembly surface automatic flaw detection equipment comprises an inverted-concave integrated box body used for part integration and a cantilever rod with the surface to be sprayed with liquid, and a transfer manipulator used for grabbing materials is arranged on the outer side of the integrated box body; a liquid spraying device is arranged in the integrated box body, a liquid circulating device is arranged below the liquid spraying device, and a detection device is arranged on the opposite side of the liquid circulating device. According to the automatic flaw detection equipment and method for the surface of the railway cantilever assembly, dropped flaw detection liquid enters the conveying cavity in a centralized mode to be collected, in order to recycle the flaw detection liquid co
