Description

Radiology transillumination fixture for precision casting parts Technical Field The utility model relates to the technical field of radiation detection, in particular to a radiation transillumination tool for precision casting parts. Background The precision casting component has severe performance requirements due to the influence of factors such as working environment, temperature, working condition and the like. If metallurgical defects exist in the precision casting part, serious potential safety hazards are generated, so that the structural quality of the inside of the part is required to be checked in a radiology transillumination detection mode during production, 100% radiology detection is usually adopted in transillumination detection, the detection quantity is large, and the requirement on consistency of the negative film is high, so that the requirement on the placement position and angle of the workpiece is high. For example, for transmission detection of aviation precision casting blades, the blade edge plate and blade bodies and tenons usually form a complex T-shaped or L-shaped structure, no general tool is used when the blade edge plate is placed, a foam seat is used as a support to ensure the position and angle of a workpiece relative to a radiology transilluminator, defects (such as inclusions and looseness) of the blade edge plate mostly occur at the corner connected with the blade bodies or the cavity position inside the edge plate, the conventional vertical transillumination can enable the edge plate to overlap with the blade body images, and the edge plate is often provided with weight-reducing grooves or air film holes and is extremely sensitive to transilluminating angles.
