The technical scheme of the invention is as follows:
general quick location detection frock of welded structure spare ray detection includes: the device comprises a base body, a base, a top block, a right-angle supporting surface and a groove;
the base body is fixed in an included angle formed by the right-angle supporting surfaces and forms an included angle of 45 degrees with both supporting surfaces of the right-angle supporting surfaces, a groove is formed in the middle position of the included angle, and the width of an opening at the lowest end of the groove is larger than the outer diameter of the part, so that the ray incidence angle and the part fixing can be flexibly adjusted; each supporting surface is respectively provided with a top block; the bottom of each supporting surface is provided with 1 base.
The upper surface of the base is herringbone; the included angle between the upper surface of each base and the horizontal plane is between 10 degrees and 15 degrees, so that the ray incidence angle and the fixed parts can be flexibly adjusted.
The opening width of the lowest end of the groove is 1mm-2mm larger than the outer diameter of the part.
The matrix consists of two triangular plates and two rectangular plates.
The groove and the top block are used for positioning the part.
The shape of the positioning block is matched with the angle of the part.
Two positioning blocks are arranged on the same supporting surface.
The invention has the advantages that: the device can be quickly installed and positioned, and the ray incidence angle can be quickly adjusted, so that the ray detection efficiency is improved, and the detection cost is reduced. The test proves that the detection efficiency is improved by more than 3 times, and the detection requirement of batch production of welding parts is met.
