Abstract
The invention relates to the technical field of nondestructive inspection of aluminum alloy die castings, in particular to a detection method of a cylindrical aluminum alloy die casting sandwich leather, which comprises an ultrasonic flaw detector (1), a water immersion probe (7), a water tank (2) and a turntable (3), the water tank (2) is filled with water, the turntable (3) is placed at the bottom of the water tank (2), a cylindrical aluminum alloy die casting (4) is placed on the turntable (3), and the ultrasonic flaw detector (1) is connected with the water immersion probe (7). The inner hole wall of the cylindrical aluminum alloy die casting (4) is attached to the profiling detection face of a profiling wedge block (5), a water immersion probe (7) is fixedly connected into an inner groove of the profiling wedge block (5) through a fixing screw (6), and the water immersion probe (7) is connected with an ultrasonic flaw detector (1) through a wiring harness. The problem that the aluminum die casting has the skin clamping defect can be accurately and efficiently found out, the skin clamping detection rate is 100% through actual application, and the detection requirement is met.
