Description

Supporting device for X-ray detection of narrow weld joint of aero-engine casing support plate Technical Field The invention relates to a supporting device, in particular to a supporting device for X-ray detection of a narrow weld joint of a support plate of an aero-engine box, and belongs to the technical field of design and manufacture of aero-engine maintenance process equipment. Background The air inlet channel is a channel for sucking air of the aero-engine, and belongs to one of five parts of the aero-engine. The air inlet casing component is an important component of an air inlet channel of an aeroengine, and mainly comprises a support plate, adjustable blades and a bearing ring at the forefront end of the aeroengine. Therefore, the quality of the air inlet casing assembly is directly related to the normal operation of all parts of the aeroengine, and if the air inlet casing assembly has faults such as crack and block falling of a support plate, falling of an adjustable blade and the like in the use process, the engine is easily damaged seriously, and further, grade flight accidents are caused, so that the loss is immeasurable. Because the repair of the replacement support plate of the air inlet casing assembly is to perform in-situ electron beam welding, the quality of the welding seam is detected by the X-ray of the replacement support plate of the air inlet casing assembly, the length of the welding seam is detected to be about 10mm, the width is about 1mm, and the thickness is about 1.5 mm.
