[0002] Steel parts usually need to be inspected after welding to check whether they are damaged during the welding process and whether the welds meet the requirements. The existing technology usually uses digital ultrasonic detectors for inspection. Digital ultrasonic detectors are suitable for the inspection of internal defects of various low-carbon steel, low-alloy steel, austenitic stainless steel and some high-attenuation metal or non-metallic materials, plates, welded joints, forgings, castings, pipe fittings, etc. During the inspection, a clamping mechanism is required to fix the steel parts.

[0003] When clamping steel parts, the existing clamping mechanism usually cannot conveniently fix and loosen the steel parts, which makes it troublesome for people to take the steel parts out of the clamping mechanism. In addition, the steel parts cannot rotate on the clamping mechanism, and the detection device cannot detect the position between the steel parts and the clamping mechanism, which brings certain adverse effects to the steel part detection process. In order to solve the shortcomings of the existing technology, we propose a clamping mechanism for non-destructive testing of steel parts. Utility Model Content
