Problems solved by technology
Because the spray boom is small, it is time-consuming and labor-intensive to place on the ground, and the efficiency is low. The air in the X-ray flaw detection machine room is degraded after being ionized by high-voltage X-rays. Staying for a long time will cause discomfort to the inspectors, and it cannot meet the 90° requirement. Precise rotation with large errors

The invention discloses a radiographic testing device and method for spray rod welds. The device comprises a base (1), wherein a row of round holes are distributed in one end surface of the base (1) in the length direction of the base (1), a left stop lever (2) and a right stop lever (6) are arranged in the round hole at the leftmost end and the round hole at the rightmost end respectively, a plurality of L-shaped rotating rods (3) are arranged in the round holes between the left stop lever (2) and the right stop lever (6), short sides of the plurality of L-shaped rotating rods (3) are connected through a connecting plate (5), and threads are formed in outer surfaces of the tail ends of long sides of the L-shaped rotating rods (3), and spray rod connecting holes are formed in the tail ends of the long sides of the L-shaped rotating rods (3). Spray rods (7) are arranged orderly outside a machine room by use of starting time, films are arranged when an X-ray machine shuts down, the spray rods (7) can be wholly rotated by 90 degrees instantly, the testing efficiency is improved, the testing accuracy is improved, and standing time of testing workers in the machine room is shortened.
Description
technical field [0001] The invention belongs to the technical field of radiation flaw detection of spray rod welds in aero-engine combustion chambers, in particular to a ray flaw detection fixture for spray rod welds in aero-engine combustion chambers and a use method. Background technique [0002] At present, when performing radiographic flaw detection on the spray rod weld seam of the aero-engine combustion chamber, it is necessary to place multiple spray rods on one X-ray film, perform transillumination, and then change another X-ray film to rotate the spray rods. Transilluminate at 90°, and finally develop and evaluate the exposed X-ray film. Because the spray boom is small, it is time-consuming and labor-intensive to place on the ground, and the efficiency is low. The air in the X-ray flaw detection machine room is degraded after being ionized by high-voltage X-rays. Staying for a long time will cause discomfort to the inspectors, and it cannot meet the 90° requirement....
