[0003] However, due to the manual operation of the probe, it is difficult to achieve full-coverage inspection of the surface of the aircraft hub. In order to ensure full-coverage inspection of the aircraft hub, it is often necessary to scan the same area of the aircraft hub multiple times, and the detection efficiency is low.

The invention relates to the field of aircraft hub flaw detection, and particularly relates to an aircraft hub surface automatic flaw detection device which comprises a mounting base, a rotary table rotatably connected to the mounting base, a limiting device used for fixing the position of an aircraft hub and a probe used for carrying out flaw detection on the aircraft hub. A horizontal driving part is mounted on the mounting base, a vertical driving part is fixedly connected to the horizontal driving part, a mounting frame is arranged on the vertical driving part, and the probe is flexibly connected with the mounting frame so as to swing around the joint of the probe and the mounting frame; the horizontal driving part is configured to be capable of stopping when the probe abuts against the aircraft hub and the swing angle of the probe is larger than a set value, and is started when the swing angle is smaller than the set value; and the vertical driving part is started when the probe abuts against the aircraft hub and the swing angle of the probe is larger than the set value, and is stopped when the swing angle is smaller than the set value. According to the invention, full-coverage detection can be carried out on the surface of the aircraft hub during detection, and the detection efficiency is improved.
Description
technical field [0001] The present application relates to the field of flaw detection of aircraft hubs, in particular to an automatic flaw detection device for the surface of aircraft hubs. Background technique [0002] In the process of manufacturing aircraft hubs, it is necessary to perform flaw detection on the hubs. At present, when performing flaw detection on aircraft hubs, turbine flaw detection is generally used, and the probes of turbine flaw detection are generally rod-shaped. During flaw detection, the operator controls the rotation of the hub of the aircraft with one hand, and sweeps the surface of the hub evenly with the eddy current probe in the other hand. [0003] However, due to manual operation of the probe, it is difficult to achieve full-coverage detection of the aircraft hub, and in order to ensure full-coverage detection of the aircraft hub, it is often necessary to scan the same area of the aircraft hub multiple times, and the detection efficiency is...
